- Abstract
Case: We report a case of intraneural nodular fasciitis in the forearm initially suspected as a schwannoma, emphasizing the importance of accurate diagnosis. A 40-year-old woman presented with mass on the lateral aspect of her right forearm and radial neuropathy symptoms for 2 months. An excisional biopsy and histopathological examination confirmed nodular fasciitis. Postoperative evaluation at 4.5 years found no pain, paralysis, or recurrence., Conclusion: Awareness of nodular fasciitis is crucial to prevent misdiagnosis and unnecessary treatment. Despite its rapid growth, nodular fasciitis generally has an excellent prognosis without long-term consequences., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/C419)., (Copyright © 2024 by The Journal of Bone and Joint Surgery, Incorporated.)

- Abstract
Case: We present a 67-year-old woman with long finger extrinsic extensor tightness and a 56-year-old man with limited index finger flexion due to extrinsic extensor tightness secondary to tendon transfers for radial nerve palsy. Both patients underwent prior surgical procedures that led to limited range of motion (ROM). Subsequently, they elected for central tendon tenotomy (CTT), which demonstrated postoperative ROM improvement and satisfactory patient outcomes., Conclusion: Surgical management of extrinsic extensor tendon tightness of the hand is generally addressed by performing tenolysis to improve tendon excursion. We present a novel and simple technique of CTT with pertinent anatomy, descriptive cases, and a cadaveric video., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/C391)., (Copyright © 2024 by The Journal of Bone and Joint Surgery, Incorporated.)

- Abstract
The upper limb has a complex anatomy comprised of many nerve and vascular structures, making humeral shaft fractures extremely important. Injury to the humeral shaft commonly occurs due to trauma and affects younger male or older female patients. The radial nerve travels along the spiral groove of the humerus, placing it at an increased risk of damage in humeral shaft fractures. If injured, there are a variety of classifications of radial nerve injury, different indications for exploration, and treatment methods that orthopedic surgeons have available in treating these injuries. This review aims to discuss the etiology of humeral shaft fracture-associated radial nerve palsy, tools for diagnosis, and treatment., Competing Interests: Conflicts of Interest No benefits in any form have been received or will be received related directly to this article., (Copyright © 2024 American Society for Surgery of the Hand.

- Abstract
Case: This case report describes a patient with paresthesia in the distribution of the superficial sensory branch of the radial nerve that was treated with surgery. Intraoperatively, there was a unique cause of internal compression by a rare superficial radial artery variant running adjacent to it. The nerve was mobilized from the artery with fascial releases. The patient had symptom resolution postoperatively., Conclusion: To our knowledge, this cause of compression has not been described before and should be considered in a differential diagnosis. In addition, clinicians should be aware of this anatomical variant during venipunctures and surgical approaches., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/C370)., (Copyright © 2024 by The Journal of Bone and Joint Surgery, Incorporated.)

- Abstract
This article reports a case of a female patient admitted with swelling and subcutaneous mass in the right forearm, initially suspected to be multiple nerve fibroma. However, through preoperative imaging and surgery, the final diagnosis confirmed superficial thrombophlebitis. This condition resulted in entrapment of the radial nerve branch, leading to noticeable nerve entrapment and radiating pain. The surgery involved the excision of inflammatory tissue and thrombus, ligation of the cephalic vein, and complete release of the radial nerve branch. Postoperative pathology confirmed the presence of Superficial Thrombophlebitis. Through this case, we emphasize the importance of comprehensive utilization of clinical, imaging, and surgical interventions for more accurate diagnosis and treatment. This is the first clinical report of radial nerve branch entrapment due to superficial thrombophlebitis., (© 2024. The Author(s).)

- Abstract
We report the case of a 58-year-old man who developed radial palsy three months after surgical reinsertion of the distal biceps brachii through a single anterior approach. Radiographs and ultrasound examinations revealed heterotopic ossification compressing the deep branch of the radial nerve. Surgical excision and neurolysis were performed. At the two-month follow-up, the patient was asymptomatic. Practitioners and orthopedic surgeons should be aware of the risk of heterotopic ossification after distal biceps reinsertion and its possible atypical clinical presentation., (Copyright © 2023 SFCM.

- Abstract
The association of radial nerve palsy and humeral shaft fracture is well known. Primary exploration and fracture fixation is recommended for open fractures and vascular injury while expectant management remains the standard of care for closed injuries. In the absence of nerve recovery, exploration and reconstruction is recommended 3 to 5 months following injury. When direct repair or nerve grafting is unlikely to achieve a suitable outcome, nerve and tendon transfers are potential options for the restoration of wrist and finger extension.

- Abstract
Rationale: Radial nerve palsy in the newborn and congenital radial head dislocation (CRHD) are both rare disorders, and early diagnosis is challenging. We reported a case of an infant with concurrent presence of these 2 diseases and provide a comprehensive review of the relevant literature. The purpose of the study is to share diagnostic and treatment experiences and provide potentially valuable insights., Patient Concerns: A newborn has both radial nerve palsy and CRHD, characterized by limited wrist and fingers extension but normal flexion, normal shoulder and elbow movement on the affected side, characteristic skin lesions around the elbow, and an "audible click" at the radial head. The patient achieved significant improvement solely through physical therapy and observation., Diagnoses: The patient was diagnosed with radial nerve palsy in the newborn combined with CRHD., Interventions: The patient received regular physical therapy including joint function training, low-frequency pulse electrical therapy, acupuncture, paraffin treatment, as well as overnight splint immobilization., Outcomes: The child could actively extend the wrist to a neutral position and extend all fingers., Lessons: If a neonate exhibits limited extension in the wrist and fingers, but normal flexion, along with normal shoulder and elbow movement, and is accompanied by skin lesions around the elbow, there should be a high suspicion of radial nerve palsy in the newborn., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

- Abstract
Radial neuropathy is the third most common upper limb mononeuropathy after median and ulnar neuropathies. Muscle weakness, particularly wrist drop, is the main clinical feature of most cases of radial neuropathy, and an understanding of the radial nerve's anatomy generally makes localizing the lesion straightforward. Electrodiagnosis can help confirm a diagnosis of radial neuropathy and may help with more precise localization of the lesion. Nerve imaging with ultrasound or magnetic resonance neurography is increasingly used in diagnosis and is important in patients lacking a history of major arm or shoulder trauma. Radial neuropathy most often occurs in the setting of trauma, although many other uncommon causes have been described. With traumatic lesions, the prognosis for recovery is generally good, and for patients with persistent deficits, rehabilitation and surgical techniques may allow substantial functional improvement., (Copyright © 2024 Elsevier B.V.

- Abstract
Background: This is the first systematic review of the relationship between humeral shaft fractures and radial nerve palsy in children. The present comprehensive review is aimed at identifying important clinical findings between humeral diaphysis fractures and radial nerve injuries and assessing the effects of treatment., Methods: We searched electronic bibliographic databases, including PubMed, the Cochrane Library, Scopus, and Web of Knowledge, until March 2022. This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the patients, interventions, comparisons, outcomes guidelines., Results: We identified 23 original papers, of which 10 were eligible for further analysis. Cases of 32 young patients with radial nerve palsy were identified and analyzed. The prevalence of radial nerve palsy was 4.34% (eight cases out of 184 patients with humeral shaft fractures). The radial nerve was most often associated with a simple transverse fracture (12A3, 17 cases (65.4%))., Conclusions: Radial nerve injury in humeral shaft fractures in children is rare, with a frequency of 4.34%. We highly recommend early surgical nerve exploration with transverse fractures in the distal third segment combined with primary radial palsy. Furthermore, we recommend making thoughtful decisions regarding early nerve exploration in the Holstein-Lewis fractures. In addition, consideration of early surgical nerve exploration in fractures resulting from high-energy trauma and open fractures despite their morphology is recommended., Competing Interests: All authors declare that they have no conflict of interest., (Copyright © 2023 Wiktor Łukasz et al.)

- Abstract
Introduction: With an incidence of 2-16%, radial nerve palsy is one of the common forms of nerve injuries globally. Radial nerve palsy causes debilitating effects including loss of elbow extension, wrist drop and loss of finger extension. Reparative surgical pathways range from primary repair and neurolysis, to nerve grafting, nerve transfers, and tendon transfers. Due to ease of performance and acceptability and reproducibility of outcomes, tendon transfers are considered the gold standard of radial nerve palsy repair. However, independent finger function cannot be achieved and as such may not give truly desirable results. In lower-middle income countries, the question of nerve transfer versus tendon transfer for patients who are keen to get back to work is key. While tendon transfer recovery is faster, the functional loss is often considered devastating for fine hand function due to loss of grip secondary to lack of wrist and finger extension. In this study, we present our experience of performing median nerve transfers for radial nerve palsy in Pakistan., Methods: We performed a retrospective case-series of patients undergoing median to radial nerve transfer for radial nerve palsy over a period of 6 y, from 2012 to 2019. Patients with radial nerve palsy were diagnosed via electromyography and nerve conduction studies. The procedure involved coapting the branches of the flexor carpi radialis and flexor digitorum superficialis (long and ring finger) nerves to the posterior interosseous nerve and extensor carpi radialis brevis, respectively. Patients were assessed using the Medical Research Council scale for muscle strength of wrist, finger and thumb extension separately at 1 y time. Our results were then compared to results from similar nerve transfer studies., Results: We operated on 10 right-hand dominant patients, eight males and two females with a median age of 33 y (6-63 y). four sustained injury to the right hand and six to the left. Causes of the injuries included road traffic accident (n = 3), firearm injury (n = 4), shrapnel (n = 1), iatrogenic injury (injection in deltoid region (n = 1) and fall (n = 1). Types of fracture included mid humerus fracture, fracture of the surgical neck of the humerus, and supracondylar fracture of the humerus. Median time to surgery since injury was 4 mo (1-8 mo). Independent wrist extension was M4+ in all patients and independent finger extension was M4+ in seven and M4-in two patients. However, a patient who presented late at 8 mo had poorer finger outcomes with extension at M2-. All patients had independent movement of fingers., Conclusions: Nerve transfer is a reliable method of post traumatic nerve repair and reinnervation, particularly in lower-middle income countries, even in cases where the nerve damage is severe and extensive and up to 6 mo may have elapsed between injury and presentation. Timely median to radial nerve transfer is a highly recommended option for radial nerve palsy, with regular follow-ups and physical therapy added to ensure positive outcomes., (Copyright © 2023 Elsevier Inc.

- Abstract
Radial tunnel syndrome (RTS) is caused by compression of the posterior interosseous nerve and consists of a constellation of symptoms that have previously been characterized as aspects of other disease processes, as opposed to a distinct diagnosis. First described in the mid-20th century as "radial pronator syndrome," knowledge regarding the anatomy and presentation of RTS has advanced markedly over the past several decades. However, there remains notable controversy and ongoing research regarding diagnostic imaging, nonsurgical treatment options, and indications for surgical intervention. In this review, we will discuss the anatomic considerations of RTS, relevant physical examination findings, potential diagnostic modalities, and outcomes of several treatment options., (Copyright © 2023 by the American Academy of Orthopaedic Surgeons.)

- Abstract
Introduction: Humeral shaft fractures can be treated non-operatively or operatively. The optimal management is subject to debate. The aim was to compare non-operative and operative treatment of a humeral shaft fracture in terms of fracture healing, complications, and functional outcome., Methods: Databases of Embase, Medline ALL, Web-of-Science Core Collection, and the Cochrane Central Register of Controlled Trials (CENTRAL) were systematically searched for publications reporting clinical and functional outcomes of humeral shaft fractures after non-operative treatment with a functional brace or operative treatment by intramedullary nailing (IMN; antegrade or retrograde) or plate osteosynthesis (open plating or minimally invasive). A pooled analysis of the results was performed using MedCalc., Results: A total of 173 studies, describing 11,868 patients, were included. The fracture healing rate for the non-operative group was 89% (95% confidence interval (CI) 84-92%), 94% (95% CI 92-95%) for the IMN group and 96% (95% CI 95-97%) for the plating group. The rate of secondary radial nerve palsies was 1% in patients treated non-operatively, 3% in the IMN, and 6% in the plating group. Intraoperative complications and implant failures occurred more frequently in the IMN group than in the plating group. The DASH score was the lowest (7/100; 95% CI 1-13) in the minimally invasive plate osteosynthesis group. The Constant-Murley and UCLA shoulder score were the highest [93/100 (95% CI 92-95) and 33/35 (95% CI 32-33), respectively] in the plating group., Conclusion: This study suggests that even though all treatment modalities result in satisfactory outcomes, operative treatment is associated with the most favorable results. Disregarding secondary radial nerve palsy, specifically plate osteosynthesis seems to result in the highest fracture healing rates, least complications, and best functional outcomes compared with the other treatment modalities., (© 2023.

- Abstract
Background: Historically, humeral shaft fractures have been successfully treated with nonoperative management and functional bracing; however, various surgical options are also available. In the present study, we compared the outcomes of nonoperative versus operative interventions for the treatment of extra-articular humeral shaft fractures., Methods: This study was a network meta-analysis of prospective randomized controlled trials (RCTs) in which functional bracing was compared with surgical techniques (including open reduction and internal fixation [ORIF], minimally invasive plate osteosynthesis [MIPO], and intramedullary nailing in both antegrade [aIMN] and retrograde [rIMN] directions) for the treatment of humeral shaft fractures. The outcomes that were assessed included time to union and the rates of nonunion, malunion, delayed union, secondary surgical intervention, iatrogenic radial nerve palsy, and infection. Mean differences and log odds ratios (ORs) were used to analyze continuous and categorical data, respectively., Results: Twenty-one RCTs evaluating the outcomes for 1,203 patients who had been treated with functional bracing (n = 190), ORIF (n = 479), MIPO (n = 177), aIMN (n = 312), or rIMN (n = 45) were included. Functional bracing yielded significantly higher odds of nonunion and significantly longer time to union than ORIF, MIPO, and aIMN (p < 0.05). Comparison of surgical fixation techniques demonstrated significantly faster time to union with MIPO than with ORIF (p = 0.043). Significantly higher odds of malunion were observed with functional bracing than with ORIF (p = 0.047). Significantly higher odds of delayed union were observed with aIMN than with ORIF (p = 0.036). Significantly higher odds of secondary surgical intervention were observed with functional bracing than with ORIF (p = 0.001), MIPO (p = 0.007), and aIMN (p = 0.004). However, ORIF was associated with significantly higher odds of iatrogenic radial nerve injury and superficial infection than both functional bracing and MIPO (p < 0.05)., Conclusions: Compared with functional bracing, most operative interventions demonstrated lower rates of reoperation. MIPO demonstrated significantly faster time to union while limiting periosteal stripping, whereas ORIF was associated with significantly higher rates of radial nerve palsy. Nonoperative management with functional bracing demonstrated higher nonunion rates than most surgical techniques, often requiring conversion to surgical fixation., Level of Evidence: Therapeutic Level I .

- Abstract
Background: Intramedullary humeral nailing is a common and reliable procedure for the treatment of humeral shaft fractures. Radial nerve palsy is a common complication encountered in the treatment of this pathology. The radial nerve runs from posterior to anterior at the lateral aspect of the distal humerus. Hence, there is reason to believe that due to the anatomic vicinity of the radial nerve in this area, lateral-medial distal locking in intramedullary nailing of the humerus may be associated with a greater risk for iatrogenic radial nerve injury compared to anterior-posterior locking., Questions/purpose: To assess whether the choice of distal locking (lateral-medial versus anterior-posterior distal locking) in intramedullary humeral nailing of humeral shaft fractures affects the risk for iatrogenic radial nerve injury., Patients and Methods: Overall, 203 patients (116 females, mean age 64.3 ± 18.6 years), who underwent intramedullary nailing of the humerus between 2000 and 2020 at a single level-one trauma center, met the inclusion criteria and were analyzed in this retrospective case-control study. Patients were subdivided into two groups according to the distal locking technique., Results: Anterior-posterior locking was performed in 176 patients versus lateral-medial locking in 27 patients. We observed four patients with iatrogenic radial nerve palsy in both groups. Risk for iatrogenic radial nerve palsy was almost 7.5 times higher for lateral-medial locking (OR 7.48, p = 0.006). There was no statistically significant difference regarding intraoperative complications, union rates or revision surgeries between both groups., Conclusions: Lateral-medial distal locking in intramedullary nailing of the humerus may be associated with a greater risk for iatrogenic radial nerve palsy than anterior-posterior locking. Hence, we advocate for anterior-posterior locking., Level of Evidence: Level III retrospective comparative study., (© 2022. The Author(s).)

- Abstract
Humeral fractures in arm wrestling are rarely reported entities in the orthopedic literature and can present with significant pain and debilitation. These injuries are even more uncommon in female practitioners of the sport. Rotational forces applied to the humerus during competition can result in the transmission of stress into the distal part of the humerus, thereby causing a spiral fracture. Common complications that can arise from such an injury can include radial nerve palsy and butterfly fragments of the humerus. These can occur in arm wrestling and can present with prominent pain, weakness, and functional impairment. Treatment often varies according to the presenting case and are often operative in cases with displaced fractures, and non-operative in those of nondisplaced fractures. Prognostic outcomes are often favorable and uneventful. In this article, we explore a distal humeral fracture in a female arm wrestler and discuss the mechanism, presentation, and management of such an injury, based on a thorough yet concise review of literature., Competing Interests: Disclaimers: Dr. Abboud receives royalties from DJO Global, Zimmer-Biomet, Smith and Nephew, Stryker, Global Medical, Inc., (Copyright © 2023 Marshfield Clinic Health System.)

- Abstract
Introduction: The radial tunnel syndrome (RTS) is an entrapment of the radial nerve in the forearm. It is characterized by pain focused on the trapping area in the proximal forearm as well as pain radiated down the forearm. The syndrome is more common in men and in our estimation, there is a circumstantial connection to the continuous use of the computer keyboard. Radial tunnel syndrome is a consequence of nerve entrapment in the tunnel, which is formed from a covering consisting of the supinator muscle and the distal margins of this muscle. There is a clear association between radial tunnel syndrome and the occurrence of tennis elbow. The sensitivity in nearby locations along with the lack of familiarity of some of the clinicians with RTS lead to misdiagnosis and therefore, even to mistreatment in some cases. The physical examination is the most important means of making the correct diagnosis. The treatment of radial tunnel syndrome is divided into the conservative one in which emphasis is placed on physiotherapy and mobilizations of the nerve and the surgical one during which decompression of the radial canal is performed and in fact release of pressure at the exact anatomical location.

- Abstract
The radial nerve is the biggest branch of the posterior cord of the brachial plexus and one of its five terminal branches. Entrapment of the radial nerve at the elbow is the third most common compressive neuropathy of the upper limb after carpal tunnel and cubital tunnel syndromes. Because the incidence is relatively low and many agents can compress it along its whole course, entrapment of the radial nerve or its branches can pose a considerable clinical challenge. Several of these agents are related to normal or variant anatomy. The most common of the compressive neuropathies related to the radial nerve is the posterior interosseus nerve syndrome. Appropriate treatment requires familiarity with the anatomical traits influencing the presenting symptoms and the related prognoses. The aim of this study is to describe the compressive neuropathies of the radial nerve, emphasizing the anatomical perspective and highlighting the traps awaiting physicians evaluating these entrapments., (© 2023.

- Abstract
Hereditary neuropathy with liability to pressure palsy (HNPP) is a rare autosomal dominant disease characterized by focal, recurrent, demyelinating peripheral neuropathies. It is caused by deletions of the gene encoding for peripheral myelin protein 22 (PMP22) on chromosome 17. While it may range widely, the most common clinical presentation is an acute, focal mononeuropathy with numbness or muscle weakness after trauma or compression. Diagnostic tools include electrophysiological studies, genetic tests and nerve biopsies. There is no standard surgical or pharmacological treatment. The course of the disease is usually benign, with spontaneous improvement after most episodes of peripheral nerve palsy. HNPP is best managed by early detection, preventative measures, and subsequent treatment of symptoms. According to the medical literature, operative treatment was undertaken in few cases and limited to decompression of the nerve at the classic entrapment sites of the carpal or cubital tunnels. We present a case of multiple tendon transfer (pronator teres to extensor carpi radialis brevis and flexor carpi radialis to extensor digitorum communis) with a two-year follow-up in a 24-year-old woman with HNPP who was affected by irreversible radial nerve palsy, and conclude with a review of the medical literature related to the disease., Competing Interests: The authors declare that they have no conflicts of interest.

- Abstract
Background: The purpose of this study is to determine if a standardized protocol for radial nerve handling during humeral shaft repair reduces the incidence of iatrogenic nerve palsy post operatively., Methods: Seventy-three patients were identified who underwent acute or reconstructive humeral shaft repair with radial nerve exploration as part of the primary procedure for either humeral shaft fracture or nonunion. All patients exhibited intact radial nerve function pre-operatively. A retrospective chart review and analysis identified patients who developed a secondary radial nerve palsy post-operatively. In each case, the radial nerve was identified and mobilized for protection, regardless of whether the implant necessitated the extensile exposure., Results: Fractures were classified according to AO/OTA guidelines and included 23 Type 12A, 11 Type 12B, and 3 Type 12C. Eight patients had periprosthetic fractures and 28 fractures could not be classified. All patients in the cohort were fixed with locking plates. Surgery was indicated for 36 patients with humeral nonunions and 37 patients with acute humeral shaft fractures. Of the 73 patients, 2 (2.7%) developed radial nerve palsy following surgery, one from the posterior approach and one from the anterolateral approach. Both patients exhibited complete recovery of radial nerve function by 6-month follow-up. No significant differences (p > 0.05) were found in any demographic or surgical details between those with and without radial nerve injury., Conclusions: Nerve exploration identification and protection leads to a low incidence of transient radial nerve palsy compared to the rate reported in the current literature (2.7% compared to 6-24%). Thus, radial nerve exploration and mobilization should be considered when approaching the humeral shaft for acute fracture and nonunion repairs., Level of Evidence: Level III., (© 2021.

- Abstract
Radial tunnel syndrome (RTS) is an uncommon controversial entity thought to cause chronic lateral proximal forearm pain due to compression of the deep branch of the radial nerve, without paralysis or sensory changes. Diagnostic confusion for pain conditions in this region results from inconsistent definitions, terminology, tests, and descriptions in the literature of RTS and "tennis elbow," or lateral epicondylitis. A case of bilateral RTS with signs discordant with traditionally used clinical diagnostic tests was successfully relieved with surgical decompression and led us to perform a comprehensive critical review of the condition. We delineate the controversy surrounding its diagnosis and aim to facilitate appropriate management and identify other areas for further study in this controversial condition. Clinical validity and evidence of anatomical rationale for the traditionally used Maudsley's provocative test is unclear in diagnosis of RTS or in chronic lateral elbow pain, if at all. Neither imaging nor electrophysiological studies contribute to a clinical diagnosis which is supported by short-term improvement after an injection with long-acting local anesthetic and corticosteroid. Accurate diagnosis and treatment of RTS can significantly improve quality of life, but validity and evidence for traditional clinical tests and definitions must be clarified.

- Abstract
Background: Although many studies have investigated iatrogenic radial nerve palsy (RNP) in humerus shaft fracture, there is inconsistent evidence on which approach leads to iatrogenic RNP. Moreover, no meta-analysis has directly compared the anterolateral and posterior approaches regarding iatrogenic RNP., Methods: In this systematic review and meta-analysis, the MEDLINE, Embase, and Cochrane Library databases were searched systematically for studies published before March 30, 2021. We included studies that (1) assessed the RNP in the surgical treatment of humerus shaft fracture and (2) directly compared the anterolateral and posterior approaches regarding the RNP. We performed synthetic analyses of the incidence of iatrogenic RNP and the recovery rate of iatrogenic RNP in humerus shaft fracture between the anterolateral and posterior approaches., Results: Our study enrolled nine studies, representing 1303 patients who underwent surgery for humerus shaft fracture. After exclusion of traumatic RNP, iatrogenic RNP was reported in 35 out of 678 patients in the anterolateral approach and in 69 out of 497 patients in the posterior approach. Pooled analysis revealed that the incidence of iatrogenic RNP was significantly higher in the posterior approach than in the anterolateral approach (OR = 2.72; 95% confidence interval (CI), 1.70-4.35; P < 0.0001, I
2 = 0%), but there was no significant difference in the recovery rates of iatrogenic RNP between the two approaches (OR = 1.55; 95% CI, 0.26-9.18; P = 0.63, I2 = 0%)., Conclusion: In this meta-analysis, the posterior approach showed a higher incidence of iatrogenic RNP than the anterolateral approach in the surgical treatment of humerus shaft fracture. With limited studies, it is difficult to anticipate if any particular approach favors the recovery of iatrogenic RNP., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2021 The Japanese Orthopaedic Association.

- Abstract
Background and Objectives : Due to the rarity of radial nerve palsy in humeral shaft fractures in the paediatric population and the lack of data in the literature, the purpose of our study was to report the treatment results of six children who sustained a radial nerve injury following a humeral shaft fracture. Materials and Methods: We treated six paediatric patients with radial nerve palsy caused by a humeral shaft fracture in our department from January 2011 to June 2022. The study group consisted of four boys and one girl aged 8.6 to 17.2 (average 13.6). The mean follow-up was 18.4 months. To present our results, we have used the STROBE protocol designed for retrospective observational studies. Results: We diagnosed two open and four closed humeral shaft fractures. Two simple transverse AO 12A3c; one simple oblique AO 12A2c; two simple spiral AO 12A1b/AO 12A1c and one intact wedge AO 12B2c were recognized. The humeral shaft was affected in the distal third five times and in the middle third one time. In our study group, we found two cases of neurotmesis; two entrapped nerves within the fracture; one stretched nerve over the bone fragments and one case of neuropraxia. We found restitution of the motor function in all cases. For all patients, extensor muscle strength was assessed on the grade M4 according to the BMRC scale (except for a patient with neuropraxia-M5). The differences in patients concerned the incomplete extension at the radiocarpal and metacarpophalangeal (MCP) joints. Conclusions: In our small case series, humeral shaft fractures complicated with radial nerve palsy are always challenging medical issues. In paediatric patients, we highly recommend an US examination where it is possible to be carried out to improve the system of decision making. Expectant observation with no nerve exploration is reasonable only in close fractures caused by low-energy trauma. Early surgical nerve exploration related with fracture stabilisation is highly recommended in fractures after high-energy trauma, especially in open fractures and where symptoms of nerve palsy appear at any stage of conservative treatment., Competing Interests: The authors declare no conflict of interest.

- Abstract
The global coronavirus disease 2019 (COVID-19) pandemic spurred an urgent need for vaccination and herd immunity. Recently, mRNA vaccines for COVID-19 have been used widely despite reports of several adverse events. Most adverse effects are mild, although a few are associated with neurological complications. Unfortunately, there is a scarcity of information on peripheral nerve complications after COVID-19 mRNA vaccination. We report the case of an immunocompetent young male patient who suffered from ipsilateral wrist drop with multiple lymphadenopathy in the cervical and axillary region after Pfizer-BioNTech vaccination. He experienced unilateral wrist drop, which significantly improved with corticosteroid treatment. Based on knowledge of this adverse effect, careful surveillance and increased awareness are needed for early diagnosis. To the best of our knowledge, this is the first reported case in the English literature of radial neuropathy resulting in wrist drop in a recently vaccinated and young immunocompetent patient., Competing Interests: The authors have no potential conflicts of interest to disclose., (© Copyright: Yonsei University College of Medicine 2022.)

- Abstract
Background: Postoperative radial nerve palsy (RNP) is a well-known complication of nonunion reconstruction of the humerus. The purpose of the current study is to determine if the surgical approach for nonunion reconstruction of the humerus influences the rate of postoperative radial nerve palsy., Methods: A retrospective case-control study of all humeral shaft and extraarticular distal humerus nonunion reconstructions performed between January 1, 2004, and August 31, 2021, was conducted. Patients included were over 18 years of age, had a non-pathologic humerus fracture nonunion and had intact radial nerve function prior to nonunion reconstruction. Exclusion criteria consisted of nonunions involving the proximal humerus, intraarticular fractures, and reconstructive treatment procedures with either intramedullary nail or external fixation methods. Perioperative variables were recorded and analyzed in regard to the development of postoperative RNP. A subgroup analysis was performed to assess the interaction of significant variables on the development of postoperative RNP., Results: The overall rate of postoperative RNP in this series was 6/53 (11%). However, no cases of postoperative radial nerve palsy were observed in patients who underwent nonunion reconstruction with a lateral paratricipital approach. A new RNP was seen in 4/9 (44%) of those patients who underwent a triceps splitting approach, which was significantly higher than those utilizing either an anterolateral approach (2/28, 7%) or a lateral paratricipital approach (0/16, 0%, p = 0.007)., Discussion and Conclusion: Our data suggests that the lateral paratricipital exposure decreases the risk of radial nerve injury with nonunion reconstruction of the humerus. The lateral paratricipital exposure offers the benefit of radial nerve exploration, decompression, neurolysis and protection prior to fracture manipulation and instrumentation. This study shows conventional approaches may predispose patients to a high rate of postoperative RNP, similar to that in the literature., Competing Interests: Declaration of Competing Interest Dr. Ivan Tarkin is a consultant for Stryker.

- Abstract
Supracondylar fracture of the humerus is one of the most common fractures seen in children, and posteromedial displacement of the distal fragment in extension-type supracondylar humerus fractures can cause injury to the radial nerve. A 6-year old girl who presented with symptoms of radial nerve injury after a supracondylar fracture of the right humerus with complete posteromedial displacement of the distal fragment (Gartland type III) underwent surgery where closed reduction and percutaneous pinning was performed. The patient was routinely followed up and at 6 months postoperatively no neurological improvement was seen. Exploratory surgery revealed complete discontinuation of the radial nerve at the fracture site and entrapment of the nerve stumps in healed bone callus. A gap of 2 cm was observed between nerve stumps, and sural nerve cable grafting was performed with good results. If neurological symptoms do not improve over time, appropriate differential diagnosis and, if necessary, exploratory surgery should be considered. Despite limited reports and their conflicting outcomes, sural nerve cable grafting could be a useful option to bridge the gap of discontinued nerve injury. Level of Evidence: Level IV, Case Report.

- Abstract
Background: Many patients with achondroplasia experience functional impairments because of rhizomelic upper extremities (proximal limb shortening). Bilateral humeral lengthening may overcome these functional limitations, but it is associated with several risks, such as radial nerve palsy and insufficient bone regeneration. Only a few studies have reported on patient satisfaction and functional outcome after humeral lengthening in patients with achondroplasia. Furthermore, the reported numbers of adverse events associated with lengthening procedures using external fixators vary widely., Questions/purposes: (1) Does bilateral humeral lengthening with a monolateral external fixator in patients with achondroplasia reliably improve patient function and autonomy, and what proportion of patients achieved at least 8 cm of humeral lengthening? (2) What adverse events occur after bilateral humeral lengthening with monolateral external fixators?, Methods: Between 2011 and 2019, 44 patients underwent humeral lengthening at our institution. Humeral lengthening was performed in patients with severe shortening of the upper extremities and functional impairments. In humeri in which intramedullary devices were not applicable, lengthening was performed with monolateral external fixators in 40 patients. Eight patients were excluded because they underwent unilateral lengthening for etiologies other than achondroplasia, and another four patients did not fulfill the minimum study follow-up period of 2 years, leaving 28 patients with bilateral humeral lengthening to treat achondroplasia available for analysis in this retrospective study. The patients had a median (interquartile range) age of 8 years (8 to 10), and 50% (14 of 28) were girls. The median follow-up time was 6 years (4 to 8). The median humeral lengthening was 9 cm (9 to 10) with a median elongation of 73% (67% to 78%) from an initial median length of 12 cm (11 to 13). To determine whether this treatment reliably improved patient function and autonomy, surgeons retrospectively evaluated patient charts. An unvalidated retrospective patient-reported outcome measure questionnaire consisting of nine items (with answers of "yes" or "no" or a 5-point Likert scale) was administered to assess the patient's functional improvement in activities of daily living, physical appearance, and overall satisfaction, such that 45 points was the highest possible score. The radiographic outcome was assessed on calibrated radiographs of the humerus. To ascertain the proportion of adverse events, study surgeons performed a chart review and telephone interviews. Major complications were defined as events that resulted in unplanned revision surgery, nerve injury (either temporary or permanent), refracture of the bone regenerate, or permanent functional sequelae. Minor complications were characterized as events that resolved without further surgical interventions., Results: On our unvalidated assessment of patient function and independence, all patients reported improvement at their most recent follow-up compared with scores obtained before treatment (median [IQR] 24 [16 to 28] before surgery versus 44 [42 to 45] at latest follow-up, difference of medians 20 points, p < 0.001). A total of 89% (25 of 28) of patients achieved the desired 8 cm of lengthening in both arms. A total of 50% (14 of 28) of our patients experienced a major complication. Specifically, 39% (11 of 28) had an unplanned reoperation, 39% (11 of 28) had a radial nerve palsy, 18% (5 of 28) had a refracture of the regenerate, and 4% (1 of 28) concluded treatment with a severe limb length discrepancy. In addition, 82% (23 of 28) of our patients experienced minor complications that resolved without further surgery and did not involve radial nerve symptoms. Radial nerve palsy was observed immediately postoperatively in eight of 13 segments, and 1 to 7 days postoperatively in five of 13 segments. The treatment goal was not achieved because of radial nerve palsy in 5% (3 of 56) of lengthened segments, which occurred in 7% (2 of 28) of patients. Full functional recovery of the radial nerve was observed in all patients after a median (IQR) of 3 months (2 to 5). Refractures of bone regenerates were observed in 11% (6 of 56) of humeri in 18% (5 of 28) of patients. Of those refractures, 1 of 6 patients was treated nonsurgically with a hanging cast, while 5 of 6 patients underwent revision surgery with intramedullary rodding., Conclusion: Most patients with achondroplasia who underwent humeral lengthening achieved the treatment goal without permanent sequelae; nonetheless, complications of treatment were common, and the road to recovery was long and often complicated, with many patients experiencing problems that were either painful (such as refracture) or bothersome (such as temporary radial nerve palsy). However, using a subjective scale, patients seemed improved after treatment; nevertheless, robust outcomes tools are not available for this condition, and so we must interpret that finding with caution. Considering our discoveries, bilateral humeral lengthening with a monolateral external fixator should only be considered in patients with severe functional impairments because of rhizomelic shortening of the upper extremities. If feasible, internal lengthening devices might be preferable, as these are generally associated with higher patient comfort and decreased complication rates compared with external fixators., Level of Evidence: Level IV, therapeutic study., Competing Interests: All ICMJE Conflict of Interest Forms for authors and Clinical Orthopaedics and Related Research® editors and board members are on file with the publication and can be viewed on request., (Copyright © 2022 by the Association of Bone and Joint Surgeons.)

- Abstract
Purpose: This meta-analysis compares open reduction and internal fixation with a plate (ORIF) versus nailing for humeral shaft fractures with regard to union, complications, general quality of life and shoulder/elbow function., Methods: PubMed/Medline/Embase/CENTRAL/CINAHL was searched for observational studies and randomised clinical trials (RCT). Effect estimates were pooled across studies using random effects models. Results were presented as weighted odds ratio (OR) or risk difference (RD) with corresponding 95% confidence interval (95% CI). Subgroup analysis was performed stratified for study design (RCTs and observational studies)., Results: Eighteen observational studies (4906 patients) and ten RCT's (525 patients) were included. The pooled effect estimates of observational studies were similar to those obtained from RCT's. More patients treated with nailing required re-intervention (RD 2%; OR 2.0, 95% CI 1.0-3.8) with shoulder impingement being the most predominant indication (17%). Temporary radial nerve palsy secondary to operation occurred less frequently in the nailing group (RD 2%; OR 0.4, 95% CI 0.3-0.6). Notably, all but one of the radial nerve palsies resolved spontaneously in each groups. Nailing leads to a faster time to union (mean difference - 1.9 weeks, 95% CI - 2.9 to - 0.9), lower infection rate (RD 2%; OR 0.5, 95% CI 0.3-0.7) and shorter operation duration (mean difference - 26 min, 95% CI - 37 to - 14). No differences were found regarding non-union, general quality of life, functional shoulder scores, and total upper extremity scores., Conclusion: Nailing carries a lower risk of infection, postoperative radial nerve palsy, has a shorter operation duration and possibly a shorter time to union. Shoulder impingement requiring re-intervention, however, is an inherent disadvantage of nail fixation. Notably, absolute differences are small and almost all patients with radial nerve palsy recovered spontaneously. Satisfactory results can be achieved with both treatment modalities., (© 2021.

- Abstract
Purpose: The aim of this study was to present our experience of treating humerus fracture sustained during arm wrestling., Methods: Data of patients treated in our clinic with the diagnosis of humeral shaft fracture due to arm wrestling between 2000 and 2020 was retrospectively reviewed. Data collected included age, sex, dominant arm, history of professional or experienced participation, type and laterality of fracture, presence of radial nerve palsy, other surgical complications, management (surgical or conservative), duration of union defined as the time from injury until callus was evident on the radiograph, and the range of motion of the elbow joint at the last follow-up., Results: Nineteen patients with humeral shaft fracture as a result of the arm wrestling were included. All had right arm fracture and all had right as the dominant side. All of the fractures were spiral at the distal third of the humerus and medial butterfly fragment was present in eleven (57.9%). Seven (36.8%) were treated surgically. Five (26.3%) had radial nerve palsy on admission. At last follow-up, no patient had neural deficit and none had significant loss of range of movement., Conclusion: Arm wrestling is an important cause of humerus shaft fracture. The dominant side is invariably affected. In this series all fractures were spiral type and occurred in the distal third of the humerus. One quarter of patients experienced radial nerve palsy, which can resolve spontaneously. Satisfactory results can be obtained with both conservative and surgical treatment., Level of Evidence: IV., (© 2021. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany.)

- Abstract
Purpose: The aims of the present study were to describe atraumatic proximal radial nerve entrapment (PRNE) and potential strategies for management., Materials and Methods: We performed a comprehensive search of 4 electronic databases for studies pertaining to patients with atraumatic PRNE. Studies published between 1930 and 2020 were included. Clinical presentation, nerve conduction studies, electromyography, and treatment methods were reviewed. In order to outline management strategies, 2 illustrative cases of acute PRNE were presented., Results: We analyzed 12 studies involving 21 patients with 22 PRNE (15 acute and 7 progressive). Sudden or repetitive elbow extension with forceful muscle contraction (n = 16) was the primary mechanism of injury. The two main sites of entrapment were the fibrous arch (n = 7) and hiatus of the lateral intermuscular septum (n = 7). Conservative treatment was performed in 4 patients and allowed for complete clinical recovery in all cases. The remaining 18 patients underwent epineurolysis (n = 16) or resection/repair of hourglass-like constriction (n = 2) between 1.5- and 120-months following diagnosis. Twelve patients experience complete recovery, while partial or no clinical recovery was reported in 1 and 4 cases, respectively; the outcome was unknown in 1 case., Conclusions: Atraumatic PRNE is rare and remains challenging with respect to diagnosis and treatment. Current literature suggests that primary sites of entrapment are the fibrous arch and hiatus of the radial nerve at the time of forceful elbow extension., Level of Evidence: Case series (IV) & systematic review (I)., (© 2021.

- Abstract
One of the most common complications associated with a diaphyseal humeral fracture is the development of a radial nerve injury. We conducted a study to analyze the degree of recovery and prognostic factors associated with radial nerve palsy in patients with diaphyseal humerus fractures. We retrospectively analyzed 28 patients who presented to the Hospital La Fe, Valencia, Spain, with a diaphyseal humerus fracture associated with radial nerve injury between 2010 and 2020. A total of 14.3% (n = 4) of the patients in our cohort had open fractures and 85.7% (n = 24) had closed fractures. There were no statistically significant differences between the type of treatment and the type of fracture (p = .13). There were also no significant differences between the type of treatment and recovery time (p = .42). There was a statistically significant difference (p = .04) in the mean recovery time for patients with preoperative radial nerve injuries (11.9 months) compared with patients who sustained a radial nerve injury secondary to surgical repair of the fracture (8.6 months). The difference in recovery time between patients with open and closed fractures was not statistically significant (p = .3). Results of the study showed that the type of fracture (i.e., open or closed) did not affect radial nerve palsy recovery time. Patients who sustain radial nerve injuries secondary to a surgical repair have a shorter recovery time than patients who sustain primary radial nerve injuries., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 International Society of Plastic and Aesthetic Nurses.

- Abstract
While high-voltage electrical injuries usually cause severe burn wounds and axonal polyneuropathy, low-voltage electrical injuries cause limited cutaneous wounds and demyelinating mononeuropathy, of which the median and ulnar nerves are the most commonly involved. We present the case of a 42-year-old man who suffered a 480-voltage electrical injury at his right elbow, resulting in a 24 × 10 cm fourth-degree burn wound and immediate radial nerve palsy. The burn wound was debrided with confirmation and preservation of radial nerve continuity. The wound was covered with a free anterolateral thigh flap and it healed uneventfully. The Tinel's sign continued to advance at follow-up, and electrodiagnostic studies showed progressive reinnervation. His radial nerve function recovered completely in 9 months. This is a rare case of low-voltage electrical injury with a fourth-degree burn wound and immediate radial nerve palsy. We treated the wound aggressively with early debridement and prompt flap coverage, but conservatively treated the radial nerve injury. The nerve recovery course indicates that it had a "shocked-cooked" injury and served itself as a well-placed nerve graft for the subsequent regeneration. We believe that our successful outcome in this case can provide more insights into the management of such injuries., (© The Author(s) 2022.

- Abstract
Background: Humeral shaft fractures are relatively rare in the paediatric population. The purpose of our study was to retrospectively evaluate all humeral shaft fractures treated at a children's trauma centre and assess cases involving radial nerve injury., Material and Methods: We retrospectively evaluated a group of 5 skeletally immature patients with radial nerve palsy out of a total of 104 patients with humeral shaft fractures treated in our hospital between January 2011 and December 2021., Results: The study group consisted of four boys and one girl aged 8.6 to 17.2 years (average age 13.6). Mean follow-up duration was 18.4 months. We diagnosed two open and three closed fractures. There were two cases of neurotmesis, two cases of nerve entrapment within the fracture site and one case of neuropraxia. Bone union and functional recovery was achieved in all five patients., Conclusions: 1. Humeral shaft fractures complicated with radial nerve palsy are a challenging medical problem; 2. The incidence of radial nerve injury in the paediatric population is significantly lower than in adults; in our study, it accounted for 4.8% of all humeral shaft fractures; 3. Expectant observation without nerve exploration is reasonable in fractures caused by a low-energy trauma; 4. Early surgical nerve exploration combined with fracture stabilisation is highly recommended in fractures due to a high-energy trauma.

- Abstract
Background: A palmaris longus (PL) to extensor pollicis longus (EPL) is a standard tendon transfer used to restore thumb extension in patients with radial nerve palsy. This transfer is done by withdrawing the EPL from the third compartment and passing it subcutaneously to reach the PL. We modified this transfer by rerouting the EPL through the second extensor compartment to improve the retropulsion of the thumb. The aim of this study is to report the outcomes of this modified transfer. Methods: Four patients with traumatic radial nerve palsy underwent the modified PL to EPL transfer. They also underwent transfer of the pronator teres (PT) to extensor carpi radialis brevis (ECRB) and flexor carpi radialis (FCR) to extensor digitorum communis (EDC). Patients were followed up for at least 1 year after surgery. The data with regard to age, gender, cause of radial nerve palsy, duration between injury and surgery, and duration of follow-up was recorded. At final follow-up, the arc of motion at the interphalangeal joint (IPJ), metacarpophalangeal joint (MCPJ), palmar and radial abduction and retropulsion were measured for the reconstructed thumb and contralateral normal thumb. Results: All patients were male, with a mean age of 34.3 (range, 19-46) years. The mean duration between the injury and surgery was 15.9 (7-27) months, and the mean post-operative follow-up period was 16.8 (12-25) months. All patients recovered good thumb function. The mean arc of motion of the affected and contralateral thumb were IPJ flexion: 52°/80°; IPJ extension: 21°/14°; MCPJ flexion: 30°/33°; MCPJ extension:24°/31°; radial abduction: 70°/74°; palmar abduction: 68°/75° and retropulsion: 4.8cm/5.0cm. Conclusion: Rerouting the PL to EPL tendon transfer through the second extensor compartment in radial nerve palsy can restore good thumb function especially retropulsion. Level of Evidence: Level IV (Therapeutic).

- Abstract
Background: In many cases the treatment of humeral shaft fractures is challenging and despite the large diversity of available approaches, no standard treatment exists. In addition to conservative treatment, intramedullary nails and plate osteosynthesis are competing methods for healing humeral shaft fractures. Furthermore, cerclage is considered to be an additive treatment for spiral fractures; however, this also increases the risk of radial nerve neuropathy and is said to compromise the perfusion of bone fragments. The goal of this study was to investigate secondary radial nerve neuropathy using additive and limited invasive cerclages for nail osteosynthesis of humeral shaft fractures., Methods: In the present study a total of 102 patients with humeral shaft fractures were clinically and neurologically re-examined after having been treated with nail osteosynthesis and additive cerclage via a limited invasive access over the past 5 years. In total 193 cerclages with limited invasive access were inserted during this time period., Results and Conclusion: Of the patients four (3.9%) showed a secondary radial neuropathy during operative stabilization. Neurophysiological and neurosonographic examinations revealed that this had not been caused by compromising, embedding or severance of the radial nerve due to the cerclage. Two out of these nerve lesions recovered spontaneously within 3 and 6 months, respectively. The other two cases could not be documented over a period of 12 months due to death of the patient. With 3.9% of iatrogenic radial nerve lesions the rate of nerve lesions falls into the lower range of that which has previously been described in the literature for nerve lesions due to operative treatment of humeral shaft fractures (3-12%). We thus conclude that there is no increased risk for iatrogenic injury of the radial nerve using additive and limited invasive cerclage., (© 2021. The Author(s).)

- Abstract
Introduction: Nerve palsy is common after humeral shaft fracture, with the radial nerve being the most commonly injured nerve. Isolated nerve injuries usually recover spontaneously, and operative intervention is rarely indicated. Our goal was to study the predictors of traumatic nerve injury and recovery in a large cohort of patients with humeral shaft fractures., Methods: A total of 376 patients with humeral shaft fracture, including 96 patients with documented traumatic nerve palsy and 280 with intact neurovascular examination on presentation, were retrospectively included in the study. The primary outcome was incidence of a traumatic nerve palsy, and the secondary outcome was nerve recovery., Results: Nerve palsy was present in 96 patients (25.5%) at the time of injury. Radial nerve was the most commonly injured nerve (93.6%), followed by the ulnar (5.1%) and axillary (1.2%) nerves. Seventeen patients (17.7%) had multiple nerves palsies. A multivariable regression analysis revealed that the concomitant vascular injury (odds ratio [OR] 52, 95% confidence interval [CI] 5.6-480.6), distal one-third fractures (OR 6.3, 95% CI 2.7-14.7), and middle one-third (OR 2.8, 95% CI 1.2-6.5) vs. proximal fractures, open fracture (OR 2.1, 95% CI 1.1-4.4), and high-energy trauma (OR 1.7, 95% CI 1.1-2.9) were independent predictors of nerve palsy. Iatrogenic nerve injury was detected in 7 patients (4.6%), all affecting the radial nerve. Spontaneous recovery of traumatic nerve injuries was detected in 87 patients (91%), with 19% partial and 72% complete recovery. The initial sign of recovery was observed at median times of 7 and 9 weeks for those managed conservatively or fracture fixation. Operative treatment of the fracture had no effect on the outcome of nerve recovery (88.5% vs. 100%, P = .14). Ten patients (14.1%) had transected nerves at the time of exploration and open fractures (22.7% vs. 6.8%, P = .04), and concomitant vascular injury (33.3% vs. 7.3%, P = .02) were associated with nerve transection, portending a worse prognosis for nerve recovery compared with nerves in continuity (40% vs. 95.3%, P = .004)., Discussion: The incidence of nerve injury after humeral shaft fracture was 25%, reflecting an abundance of high-energy and open injuries in this cohort. Ninety-one percent of patients experienced improvement in their nerve function with a median time to recovery of 7-9 weeks. Operative treatment of the fracture did not change the rate of nerve recovery. Patients with multiple nerve palsies and concurrent vascular insult had worse nerve recovery. We recommend nerve studies if no sign of recovery is observed by 9 weeks., (Copyright © 2021 Journal of Shoulder and Elbow Surgery Board of Trustees. Published by Elsevier Inc. All rights reserved.)

- Abstract
Background: Radial nerve palsy is a common complication associated with humeral shaft fractures. The purposes of this study were (1) to evaluate the status of primary radial nerve palsy in patients with humeral shaft fracture according to injury mechanism, (2) to estimate the risk factors of primary RNP, and (3) to evaluate whether early exploration is helpful for radial nerve recovery., Methods: This study analyzed 162 patients with humeral shaft fractures from January 2014 to December 2019. All patients were surgically treated in our hospital. Of these, 109 high-energy injuries were identified and compared with 53 low-energy injuries. The risk factors of radial nerve palsy were analyzed, and the prevalence of radial nerve palsy and status of radial nerve exploration according to injury mechanism were evaluated. Nerve recovery rate according to early nerve exploration was investigated., Results: There were 31 cases of radial nerve palsy among 162 patients: 27 in the high-energy humeral shaft fracture group and 4 in the low-energy humeral shaft fracture group. Logistic regression analysis for risk factors showed that the injury mechanism was significantly associated with primary radial nerve palsy. Among 31 radial nerve palsy patients, 21 radial nerves were explored and 19 radial nerves recovered completely (80.6%). In the high-energy humeral shaft fracture group, 18 radial nerves were explored during surgery among 27 radial nerve palsy cases, and 16 cases recovered (88.9%). The other 9 radial nerves were not explored, and only 5 cases recovered (55.6%)., Conclusions: This study confirmed that the incidence of radial nerve paralysis was higher in high-energy humeral shaft fractures than in low-energy fractures. The more common fracture patterns were oblique, transverse, wedge, and comminuted in high-energy humeral shaft fracture. This study suggests that these patterns are not directly associated with radial nerve palsy, but that high-energy injury is associated with a specific fracture pattern. Early nerve exploration during surgical treatment in patients with radial nerve palsy associated with humeral shaft fracture was helpful especially after high-energy injury., (Copyright © 2021 Journal of Shoulder and Elbow Surgery Board of Trustees.

- Abstract
Wrist drop post-venepuncture is uncommon. There has been reported cases of direct injury to the radial nerve during venepuncture but to our knowledge, there has never been a case of posterior interosseous nerve (PIN) injury. A 34-year female, right hand dominant homemaker, with a newly diagnosed diabetes mellitus, was admitted for diabetic ketoacidosis. There was difficult access with multiple attempts in her blood taking over the antebrachial fossa and forearm. Thereafter, she was unable to fully extend her wrist, fingers and thumb with an intact sensation. The electrophysiological study was suggestive of demyelinating right radial neuropathy at the elbow. Despite the transient blood taking session, patient developed neuropraxia, which only resolved after four months. We wish to report this case of unusual presentation of a PIN palsy post- routine venepuncture, which can result in high morbidity to a patient. Key Words: Posterior interosseous nerve syndrome, venepuncture, neuropraxia, wrist drop.

- Abstract
Background: The aim of this study was to retrospectively evaluate patients who underwent surgery in our department for radial nerve lesions in terms of surgical outcomes., Methods: Thirty-eight patients were admitted to our department with radial nerve lesion. Twenty-seven of the patients had entrapment neuropathy and 11 had radial nerve injury secondary to other traumas. Various factors such as surgical results, time to surgical intervention, injury mechanism, and reconstruction technique were analyzed., Results: In all of 27 patients who were operated for radial nerve entrapment neuropathy, a complete improvement in wrist dorsal flexion was detected at postoperative 3rd month. Seven of the 11 patients who were operated for radial nerve lesion had different degrees of improvement in wrist dorsal flexion at the postoperative 3rd month. Two of the seven patients underwent anastomosis using a sural nerve graft. The recovery rate in our series was 89%. Three of the 4 patients who did not recover after the radial nerve injury were the patients who were operated within the 1st month after the trauma., Conclusion: Better functional results were obtained in the postoperative period in patients who were operated after the 1st month, underwent internal neurolysis and used a short nerve graft for anastomosis in the radial nerve lesions. In patients with entrapment neuropathy, the earliest surgery revealed satisfactory results in the postoperative period.

- Abstract
Background: Retrospective study to examine secondary radial nerve palsy after humeral shaft fixation with closed locked intramedullary nailing., Materials and Methods: Patients were identified from the hospitals' registration systems for humeral shaft fractures, nerve lesions, plating, nailing and external fixation during a 10-year period from January 2007 to December 2016. All radial nerve lesions were registered and followed-up in patient files., Results: 89 patients with locked intramedullary nailing were available for an outpatient follow-up. Mean age was 67 years at the time of injury. 72 fractures were non-pathological. Of these, 31 were nonunions. 28, 61 and zero were identified in the proximal, middle and distal thirds of the humeral shaft respectively. 76 procedures were closed and 13 were with open reduction. Six radial nerves had nerve exploration. Eight patients developed immediate postoperative radial nerve palsies. Of these, six developed after closed surgery, two after nerve exploration. Of seven available patients with a radial nerve palsy, six of these remitted. Two patients were later surgically explored. One patient out of 89 sustained a verifiable permanent radial nerve paralysis., Conclusions: In this study, the risk of a radial nerve palsy was 7.9 % with closed locked intramedullary nailing. This study suggests that exploration of the radial nerve is not necessary routinely in order to prevent radial nerve lesions when performing closed intramedullary nailing for humeral shaft fractures in adults with a preoperative normal radial nerve function., Level of Evidence: Level IV.
