Abstract Objective Guyon’s canal syndrome is caused by compression of the ulnar nerve at the wrist, occasionally requiring decompression surgery. In recent times, minimally invasive approaches have gained popularity. The aim of this study was to assess the efficacy and safety of ultrasound-guided thread release for transecting the palmar ligament in Guyon’s canal without harming surrounding structures, in a cadaveric specimen model. Methods After ethical approval, thirteen ultrasound-guided thread releases of Guyon’s canal were performed on the wrists of softly embalmed anatomic specimens. Cadavers showing injuries or prior operations at the hand were excluded. Subsequently, the specimens were dissected, and the outcome of the interventions and potential damage to adjacent anatomical structures as well as ultrasound visibility were evaluated with a score from one to three. Results Out of 13 interventions, a complete transection was achieved in ten cases (76.9%), and a partial transection was documented in three cases (23.1%). Irrelevant lesions on the flexor tendons were observed in two cases (15.4%), and an arterial branch was damaged in one (7.7%). Ultrasound visibility varied among specimens, but essential structures were delineated in all cases. Conclusion Ultrasound-guided thread release of Guyon’s canal has shown promising first results in anatomic specimens. However, further studies are required to ensure the safety of the procedure. Relevance statement Our study showed that minimally invasive ultrasound-guided thread release of Guyon’s canal is a feasible approach in the anatomical model. The results may provide a basis for further research and refinement of this technique. Key points • In Guyon’s canal syndrome, the ulnar nerve is compressed at the wrist, often requiring surgical release. • We adapted and tested a minimally invasive ultrasound-guided thread release technique in anatomic specimens. • The technique was effective; however, in one specimen, a small anatomic branch was damaged.

Postoperative ulnar neuropathy (PUN) is an injury manifesting in the sensory or motor distribution of the ulnar nerve after anaesthesia or surgery. The condition frequently features in cases of alleged clinical negligence by anaesthetists. We performed a systematic review and applied narrative synthesis with the aim of summarising current understanding of the condition and deriving implications for practice and research. Electronic databases were searched up to October 2022 for primary research, secondary research, or opinion pieces defining PUN and describing its incidence, predisposing factors, mechanism of injury, clinical presentation, diagnosis, management, and prevention. We included 83 articles in the thematic analysis. PUN occurs after approximately 1 in 14 733 anaesthetics. Men aged 50–75 yr with pre-existing ulnar neuropathy are at highest risk. Preventative measures, based on consensus and expert opinion, are summarised, and an algorithm of suspected PUN management is proposed, based upon the identified literature. Postoperative ulnar neuropathy is rare and the incidence is probably decreasing over time with general improvements in perioperative care. Recommendations to reduce the risk of postoperative ulnar neuropathy are based on low-quality evidence but include anatomically neutral arm positioning and padding intraoperatively. In selected high-risk patients, further documentation of repositioning, intermittent checks, and neurological examination in the recovery room can be helpful. [ABSTRACT FROM AUTHOR]

Background The clinical results of conservative treatment options for ulnar compression at the elbow have not been clearly determined. The aim of this review was to evaluate available conservative treatment options and their effectiveness for ulnar nerve compression at the elbow. Methods In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, a systematic review and meta-analysis of studies was performed. Literature search was performed using Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL). Results Of the 1,079 retrieved studies, 20 were eligible for analysis and included 687 cases of ulnar neuropathy at the elbow. Improvement of symptoms was reported in 54% of the cases receiving a steroid/lidocaine injection (95% confidence interval [CI], 41–67) and in 89% of the cases using a splint device (95% CI, 69–99). Conclusions Conservative management seems to be effective. Both lidocaine/steroid injections and splint devices gave a statistically significant improvement of symptoms and are suitable options for patients who refuse an operative procedure or need a bridge to their surgery. Splinting is preferred over injections, as it shows a higher rate of improvement.

The ulnar nerve (UN) is the main nerve responsible for innervation of the intrinsic musculature of the hand. It is of great importance to have a deep anatomical knowledge of the UN. The aim of this study is to enrich the knowledge of the UN anatomy at the wrist and provide useful reference information for clinical and surgical applications. In this descriptive cross-sectional study, 44 upper limbs of fresh cadavers were evaluated. The UN, the superficial branch of the ulnar nerve (SBUN), and the deep branch of the ulnar nerve (DBUN) were evaluated. Morphometric variables were measured using a digital caliper, and samples of nervous tissue were taken to evaluate the histomorphometry. Before entering the Guyon's canal, the UN had a diameter of 3.2 ± 0.4 mm. In 36 samples (82 %) the UN presented a bifurcation pattern and in the remaining 8 samples (18 %) a trifurcation was shown. The diameter of the DBUN was 1.9 ± 0.33 mm and that of the SBUN was 1.29 ± 0.22 mm. In the bifurcation patterns, the SBUN had a trunk of 5.71 ± 1.53 mm before bifurcating into the common digital nerve (fourth and fifth fingers) and an ulnar digital collateral nerve (fifth finger). The DBUN had an area of 2.84 ± 0.7 mm2 and was made up of 8 ± 1.4 fascicles and 3595 ± 465 axons. The SBUN area was 1.31 ± 0.27 mm2, it was made up of 6 ± 1.1 fascicles and 2856 ± 362 axons. The reported findings allow the hand surgeon to improve his understanding of the clinical signs of patients with UN pathologies at the wrist level and thus achieve greater precision while planning and performing surgical approaches and dissections.

- Abstract
Guyon canal (GC) syndrome is a rare peripheral neuropathy involving the distal part of the ulnar nerve. Several causes are associated with GC syndrome, including anatomic variations, space-occupying tumors, and trauma. Because of disease rarity, the only reported studies of GC syndrome are case series with small sample size. We conducted a multicenter study to identify the basic characteristics of patients with surgically treated GC syndrome and the risk factors for the disease. This retrospective multicenter study was conducted between January 2001 and December 2020. We screened 70 patients who underwent GC release surgery by seven hand surgeons at six institutes. A total of 56 patients were included in this study, including 38 patients (67.9%) who underwent isolated GC decompression and 18 (32.1%) who underwent combined peripheral nerve decompression. The mean patient age was 48.4 years (range: 20–89 years), and 40 patients (71.4%) were male. The average preoperative symptom duration was 18.5 months, and most patients were office workers. Ultrasound was positive for GC syndrome in 7/10 patients evaluated, CT in 2/5, MRI in 17/23, and electrodiagnostic studies in 35/44. The most common cause of GC syndrome was tumor (n = 23), followed by idiopathic (n = 17), trauma (n = 12), anatomic variants (n = 3), and inflammation (n = 3). In conclusion, most patients with GC syndrome in this study were male and had symptoms in one wrist. The most common cause of GC syndrome in this study was a tumor, including a ganglion cyst.

This study provides an overview on occupational demographics of a population with surgically treated carpal tunnel syndrome (CTS) and ulnar nerve entrapment at the elbow (UNE). Manual workers with CTS had more symptoms preoperatively than non-manual workers, which might be useful information for treating physicians when counseling patients. Objective: We investigated whether certain occupations were over-represented among surgically treated carpal tunnel syndrome and ulnar entrapment at the elbow, and if manual occupation affected surgical outcome. Methods: We included 9030 patients operated for CTS and 1269 for UNE registered in the Swedish National Quality Register for Hand Surgery (HAKIR) 2010–2016. Occupational data was retrieved from Statistics Sweden. Outcome was assessed using the QuickDASH questionnaire. Results: In patients operated for CTS, there were more assistant nurses, attendants/care providers/personal assistants, nannies/student assistants, carpenters/bricklayers/construction workers, cleaners, nurses, and vehicle mechanics than in the general population. In the UNE population, assistant nurses and attendants/care providers/personal assistants were over-represented. Manual workers with CTS scored the preoperative QuickDASH higher than non-manual workers. Conclusions: Manual workers are overrepresented among surgically treated CTS and UNE. Manual workers with CTS have more symptoms preoperatively than non-manual workers. [ABSTRACT FROM AUTHOR]

A recent study from Tamil Nadu, India, focuses on cubital tunnel syndrome (Cu TS), which is the second most common upper extremity compressive neuropathy after carpal tunnel syndrome. The study highlights the potential role of the anconeus epitrochlearis (AE) muscle in causing Cu TS and emphasizes the importance of magnetic resonance imaging (MRI) for accurate diagnosis. The researchers present a case of a 17-year-old male patient with Cu TS symptoms, including pain in the left elbow and paresthesia in the left hand. MRI imaging revealed compression of the ulnar nerve by the AE muscle. This research contributes to raising awareness about the causes and imaging findings of Cu TS. [Extracted from the article]

Background: Nerve compression disorders, such as carpal tunnel syndrome (CTS) and ulnar entrapment at the elbow (UNE), may be associated with apoptosis and neuroprotective mechanisms in the peripheral nerve that may be detected by biomarkers in the blood. The relationships between CTS and UNE and two biomarkers of apoptosis, i.e., caspase-3 and caspase-8, and the neuroprotective factor Heat Shock Protein 27 (HSP27) in plasma were examined in a population-based cohort. Method: The biomarkers caspase-3, caspase-8 and HSP27 were measured in plasma at inclusion of 4,284 study participants aged 46–68 years in the population-based Malmö Diet and Cancer study (MDCS). End-point retrieval was made from national registers concerning CTS and UNE. Independent t -test was used to examine the association between caspase-3, caspase-8 and HSP27 plasma levels and incidence of CTS and UNE. Cox proportional hazards regression was used to investigate if plasma levels of caspase-3, caspase-8 and HSP27 affected time to diagnosis of CTS or UNE. Results: During the mean follow-up time of 22 years, 189/4,284 (4%) participants were diagnosed with CTS and 42/4,284 (1%) were diagnosed with UNE. No associations were found between incident CTS or UNE and the biomarkers caspase-3, caspase-8 and HSP27 in plasma. Conclusion: The apoptotic biomarkers caspase-3 and caspase-8 and the neuroprotective factor HSP27 in plasma, factors conceivably related to a nerve injury, are not associated with the nerve compression disorders CTS and UNE in a general population.

A patient presented with an ulnar-sided left wrist injury that was sustained while batting. Advanced imaging was obtained to rule out common causes of nerve compression and evaluate the patient’s anatomy. Dynamic nerve conduction studies were necessary to confirm a diagnosis of nerve compression. Failing conservative treatments, the patient underwent exploration of Guyon canal and decompression of the ulnar nerve with complete symptom resolution. The patient presented a unique diagnostic challenge because he did not display the typical findings of chronic nerve entrapment syndromes. To the best of our knowledge, dynamic nerve compression at Guyon's canal has not previously been described. It is important to use a systematic approach to diagnosis, eliminating all other sources of compression. With appropriate diagnostic tools, nerve decompression can result in symptom relief.

A recent study conducted by the Department of Neurological Rehabilitation examined the effectiveness of physiotherapy in the treatment of cubital tunnel syndrome (CuTS). The researchers reviewed 18 studies that met the eligibility criteria, which included randomized controlled trials, case series, and case reports. The analysis of the literature suggests that physiotherapy can have a beneficial effect in reducing symptoms and improving function for patients with CuTS. However, due to the small number of randomized clinical trials and their heterogeneity, the researchers concluded that firm conclusions about the effectiveness of physiotherapy in the conservative treatment of CuTS cannot be drawn.

24. Sechenov First Moscow State Medical University Researchers Update Current Data on Cubital Tunnel Syndrome (Cubital tunnel syndrome due to an elbow injury. Case report).
- Abstract
Researchers from Sechenov First Moscow State Medical University have presented data on cubital tunnel syndrome, a condition caused by compression of the ulnar nerve within the walls of the tunnel. This syndrome leads to sensory disturbances, muscle weakness, trophic disorders, and the formation of secondary contractures. The researchers observed a 35-year-old male with compression ischemic neuropathy of the ulnar nerve and found that microsurgical decompression and neurotization led to a complete regression of symptoms. The article discusses the diagnosis, conservative, and surgical treatment of cubital tunnel syndrome. [Extracted from the article]

25. Research Results from Shandong Provincial Hospital Affiliated to Shandong First Medical University Update Knowledge of Cubital Tunnel Syndrome (Cubital Tunnel Syndrome Due to Intraneural Ganglion Cysts of the Ulnar Nerve With Joint-Cyst...).
- Abstract
A study conducted at Shandong Provincial Hospital in China examined the relationship between intraneural ganglion cysts and cubital tunnel syndrome. The researchers found that these cysts, which are connected to the ulnar nerve through an articular branch, originate from the elbow joint. The study analyzed 13 patients who underwent surgery for cubital tunnel syndrome caused by these cysts. After surgery, all patients experienced a disappearance of symptoms and improvements in pain levels, muscle function, and nerve conduction. The researchers concluded that disconnecting the articular nerve branch from the ulnar nerve during surgery eliminated the pathway for cyst recurrence and led to positive long-term outcomes.

- Abstract
A recent systematic review conducted at RWTH Aachen University Hospital in Germany has provided updated information on nerve compression syndrome, specifically focusing on the treatment of peripheral nerve compression syndromes of the upper extremities. The review found that carpal tunnel syndrome is the most common nerve compression syndrome, followed by cubital tunnel syndrome. The researchers analyzed randomized controlled trials and found that surgical treatment is considered superior to conservative treatment for carpal and cubital tunnel syndromes. However, more controlled studies are needed to establish evidence-based therapeutic recommendations for less common nerve compression syndromes. [Extracted from the article]

Ulnar tunnel syndrome (UTS) is relatively uncommon compared to the carpal tunnel or cubital tunnel syndromes. Few reports dedicated to the functional outcomes after surgical intervention of the UTS exist. Herein we compare the outcomes of patients with UTS of different etiologies.Patients diagnosed with UTS between 2016 and 2020 were recruited. Ulnar tunnel release was performed in all patients, along with other necessary osteosynthesis or reconstructive procedures in the traumatic group. Patients were followed-up every six months post-operatively. Outcomes measured include: objective evaluations, subjective questionnaires, records of clinical signs, and grading of the British Medical Research Council scale for intrinsic muscle strength.21 patients were recruited, and favorable results were noted in all of them after surgery. Traumatic UTS patients had a worse initial presentation than the non-traumatic cases, but had a greater improvement after surgery and yielded outcomes comparable with those of the patients without trauma. Patients with aberrant muscles in their wrists had better outcomes in some objective measurements than those without aberrant muscles.Ulnar tunnel release improves the outcome of patients regardless of the etiology, especially in patients with trauma-induced UTS. Thus, a proper diagnosis of the UTS should be alerted in all patients encountering paresthesia in the ulnar digits, ulnar-sided pain, weakness of grip strength, or intrinsic weakness to ensure good outcomes.

- Abstract
Background: The purpose of this study was to compare the demographic differences of the most common peripheral nerve compressions in the upper extremity-carpal tunnel syndrome (CTS), ulnar nerve compression (UNC) at the elbow, combined CTS and UNC, radial tunnel syndrome (RTS), and posterior interosseous nerve syndrome (PINS)-as a means to better understand the etiologies of each., Methods: A retrospective chart review was performed of all patients over the age of 18 years seen at our institution in the 2018 calendar year. International Classification of Diseases, Tenth Revision codes were used to identify patients with diagnoses of upper extremity peripheral nerve compressions. Demographic details and relevant comorbidities were recorded for each patient and compared with controls, who were seen the same calendar year with no neuropathies. χ
2 analyses, independent-samples t tests, and multivariate logistic regressions were performed ( P < .05)., Results: A total of 7448 patients were identified. Those with CTS were mainly women, former smokers, and diabetic (all P < .001) and with a greater average body mass index (BMI) ( P = .006) than controls. Patients with UNC were more often men and younger when compared with controls (both P < .001). A history of smoking, diabetes, and average BMI were similar between patients with UNC and controls (all P > .05). Those patients with combined CTS/UNC were mainly men, former smokers, and diabetic (all P < .001) when compared with controls. Patients with RTS/PINS were also mostly men ( P = .007), diabetic ( P = .042), and were more often current smokers ( P < .001)., Conclusions: The demographics of patients with various compressive neuropathies were not homogeneous, suggesting different etiologies., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.- Published

- Abstract
Background: Ulnar nerve entrapment at the elbow (UNE) is the second most prevalent entrapment neuropathy after carpal tunnel syndrome. The objective of this study was to evaluate the expert opinion of different surgical disciplines regarding the need for electrodiagnostic or ultrasound confirmation of UNE and, if so, which test was preferred for confirmation., Methods: A questionnaire was sent to all neurosurgeons and plastic or hand surgeons in the Netherlands to evaluate the current practice in planning surgical treatment of UNE., Results: The response rate was 36.4 % (134 out of 368). 94 % of surgeons reported that > 95 % of their patients had EDX or ultrasound studies before surgery. 80.6 % of all surgeons who responded reported that they seldom operated on UNE without electrodiagnostic confirmation. Hand surgeons (25.9 %) were more willing to operate on clinically diagnosed UNE without EDX than neurosurgeons (9.4 %) CONCLUSIONS: Dutch surgeons prefer diagnostic confirmation of UNE either by ultrasound or EDX, with a preference for EDX and the vast majority of operated patients do have either EDX or ultrasound or both before surgery. Compared to neurosurgeons, hand surgeons are more willing to operate on patients with clinically defined UNE but normal electrodiagnostic studies., Competing Interests: Conflict of interest On behalf of all authors, the corresponding author states that there is no conflict of interest., (Copyright © 2023 Elsevier B.V.

Introduction: Peripheral nerve tumors are usually benign, rare, slow-growing and little symptomatic. The objective is to describe strategies for the diagnosis and treatment of patients with benign tumors of the ulnar nerve. Methods: This retrospective study of patients who underwent surgery between 2010 and 2015 for the treatment of benign tumor of the ulnar nerve analyzed patient symptoms and demographic characteristics, complementary examinations, and surgical techniques performed. Results: The study included 17 (8%) patients, with a prevalence of women (65%) in the fourth decade of life. The tumors tended to be extrinsic, with lipoma in 6 cases (35%); others were intrinsic, including schwannoma in 17% and hamartoma in 11% of the cases. Tumor excision was complete in 83% of cases and partial in 17% of cases; nerve decompression was performed in 12 cases. Conclusion: The strategies performed here yielded good functional results in 88% of patients. The worst results were in tumors of vascular origin.

Ulnar neuropathy at the wrist is an uncommon disease and pure ulnar sensory neuropathy at the wrist is even rarer. It is difficult to diagnose pure ulnar sensory neuropathy at the wrist by conventional methods. We report a case of pure ulnar sensory neuropathy at the hypothenar area. The lesion was localized between 3 cm and 5 cm distal to pisiform using orthodromic inching test of ulnar sensory nerve to stimulate at three points around the hypothenar area. Ultrasonographic examination confirmed compression of superficial sensory branch of the ulnar nerve. Further, surgical exploration reconfirmed compression of the ulnar nerve. This case report demonstrates the utility of orthodromic ulnar sensory inching test.

Guyon canal (GC) syndrome is a rare peripheral neuropathy involving the distal part of the ulnar nerve. Several causes are associated with GC syndrome, including anatomic variations, space-occupying tumors, and trauma. Because of disease rarity, the only reported studies of GC syndrome are case series with small sample size. We conducted a multicenter study to identify the basic characteristics of patients with surgically treated GC syndrome and the risk factors for the disease. This retrospective multicenter study was conducted between January 2001 and December 2020. We screened 70 patients who underwent GC release surgery by seven hand surgeons at six institutes. A total of 56 patients were included in this study, including 38 patients (67.9%) who underwent isolated GC decompression and 18 (32.1%) who underwent combined peripheral nerve decompression. The mean patient age was 48.4 years (range: 20-89 years), and 40 patients (71.4%) were male. The average preoperative symptom duration was 18.5 months, and most patients were office workers. Ultrasound was positive for GC syndrome in 7/10 patients evaluated, CT in 2/5, MRI in 17/23, and electrodiagnostic studies in 35/44. The most common cause of GC syndrome was tumor (n = 23), followed by idiopathic (n = 17), trauma (n = 12), anatomic variants (n = 3), and inflammation (n = 3). In conclusion, most patients with GC syndrome in this study were male and had symptoms in one wrist. The most common cause of GC syndrome in this study was a tumor, including a ganglion cyst. Level of Evidence: Level IV case series.

We investigated whether certain occupations were over-represented among surgically treated carpal tunnel syndrome and ulnar entrapment at the elbow, and if manual occupation affected surgical outcome.We included 9030 patients operated for CTS and 1269 for UNE registered in the Swedish National Quality Register for Hand Surgery (HAKIR) 2010-2016. Occupational data was retrieved from Statistics Sweden. Outcome was assessed using the QuickDASH questionnaire.In patients operated for CTS, there were more assistant nurses, attendants/care providers/personal assistants, nannies/student assistants, carpenters/bricklayers/construction workers, cleaners, nurses, and vehicle mechanics than in the general population. In the UNE population, assistant nurses and attendants/care providers/personal assistants were over-represented. Manual workers with CTS scored the preoperative QuickDASH higher than non-manual workers.Manual workers are overrepresented among surgically treated CTS and UNE. Manual workers with CTS have more symptoms preoperatively than non-manual workers.

Lymphoma is a malignant tumour of the lymphatic system. Neurolymphomatosis occurs when lymphoma cells invade the peripheral nervous system (PNS). Neurolymphomatosis has been reported involving the sciatic nerve, nerve roots and within the axilla and the upper arm. It can cause nerve dysfunction depending on the involved nerve. Neurolymphomatosis involving the ulnar nerve is rare. We report a patient with neurolymphomatosis of the ulnar nerve around the elbow that presented with features of cubital tunnel syndrome. A high index of suspicion is necessary in patients with cubital tunnel syndrome that present with uncommon symptoms such as sudden onset, rapid progression and/or severe pain.

Summary Ulnar nerve (UN) entrapment is a common peripheral neuropathy and can lead to dysfunction of both sensory and motor function of the hand. Surgical release is the mainstay of treatment, but post-operative rehabilitation of UN innervated intrinsic muscles is lacking evidence. This cohort study utilized surface electromyography (EMG) and assessed the activation of UN innervated intrinsic and extrinsic hand muscles during four exercises in healthy participants. Exercises included rotating baoding balls, squeezing a stress ball or grip device every second, and repetitive finger abduction against a rubber band. Normalized percent activation of each muscle was calculated for each exercise. It was demonstrated that rubber band resistance (RBR) finger abduction showed significantly increased activation in both intrinsic muscles tested, while minimizing activation of the one tested UN innervated extrinsic muscle. Thus, to best target the intrinsic hand muscles without fatiguing extrinsic muscles, the inexpensive and practical RBR exercise is beneficial in post-UN release rehabilitation.

A study conducted at Princess Margaret Hospital in Hong Kong, China, has found that ultrasound (USG) can be used as an adjunct for the diagnosis of cubital tunnel syndrome (CuTS) with high accuracy and patient safety. The researchers compared the ultrasound size of the ulnar nerve between CuTS patients and control subjects and derived a cut-off size for diagnosis. They also found a strong negative correlation between the size of the ulnar nerve and nerve conduction velocity. The study suggests that USG can be used to diagnose CuTS and identify possible anatomical causes at the cubital tunnel. [Extracted from the article]

The ulnar nerve can be subject to numerous types of compression. The most common are cubital tunnel and ulnar tunnel syndromes, but there are many others with more uncommon etiologies. The existence of additional communicating branches, median nerve involvement, various types of injuries, and unusual anatomical variations can be a challenge for both diagnosis and treatment. This review presents a comprehensive depiction of ulnar nerve entrapment syndromes with particular reference to their anatomical background, risk factors, and clinical evaluation. Even common disorders can result from atypical morphological changes. It is important to be familiar with them as it is a key ability in daily medical practice.

Repetitive vibratory trauma in cyclists is one of the most common causes of ulnar nerve compression at the wrist. This study describes five cases of clinically suspected compression syndrome of the deep terminal branch of the ulnar nerve (DBUN) defined by high-resolution ultrasound (HRUS) with a 18-MHz linear transducer. Reliable HRUS visualization of the DBUN was feasible in all patients. The affected nerves had focally swollen and hypo-echoic changed segments. HRUS is a good imaging tool for the evaluation of a suspicious DBUN neuropathy if no electrodiagnostic testing is available or in patients with mild to moderate clinical symptoms with inconclusive electrodiagnostic results.

- Abstract
Knowledge about risks for overuse of psychoactive analgesics in patients having primary surgery for carpal tunnel syndrome (CTS) or ulnar nerve entrapment (UNE), or both, is limited. We investigated if patients with those nerve entrapment disorders have a higher risk of overuse of psychoactive analgesics (i.e., opioids and gabapentinoid drugs) before, after, and both before and after surgery than observed in the general population after accounting for demographical and socioeconomic factors. Using a large record linkage database, we analysed 5,966,444 individuals (25-80 years), residing in Sweden December 31st, 2010-2014, of which 31,380 underwent surgery 2011-2013 for CTS, UNE, or both, applying logistic regression to estimate relative risk (RR) and 95% confidence interval (CI). Overall, overuse of the psychoactive analgesics was low in the general population. Compared to those individuals, unadjusted RR (95% CI) of overuse ranged in patients between 2.77 (2.57-3.00) with CTS after surgery and 6.21 (4.27-9.02) with both UNE and CTS after surgery. These risks were only slightly reduced after adjustment for demographical and socioeconomic factors. Patients undergoing surgery for CTS, UNE, or both, have a high risk of overuse of psychoactive analgesics before, after, and both before and after surgery., (© 2023. Springer Nature Limited.)

Chang, Ke-Vin, Wu, Wei-Ting, Han, Der-Sheng, and Özçakar, Levent
- Abstract
Objective To examine the performance of sonographic cross-sectional area (CSA) measurements in the diagnosis of cubital tunnel syndrome (CuTS). Data Sources Electronic databases, comprising PubMed and EMBASE, were searched for the pertinent literature before July 1, 2017. Study Selection Fourteen trials comparing the ulnar nerve CSA measurements between participants with and without CuTS were included. Data Extraction Study design, participants' demographic characteristics, diagnostic reference of CuTS, and methods of CSA measurement. Data Synthesis Among different elbow levels, the between-group difference in CSA was the largest at the medial epicondyle (6.0mm 2 ; 95% confidence interval [CI], 4.5–7.4mm 2 ). The pooled mean CSA in participants without CuTS was 5.5mm 2 (95% CI, 4.4–6.6mm 2 ) at the arm level, 7.4mm 2 (95% CI, 6.7–8.1mm 2 ) at the cubital tunnel inlet, 6.6mm 2 (95% CI, 5.9–7.2mm 2 ) at the medial epicondyle, 7.3mm 2 (95% CI, 5.6–9.0mm 2 ) at the cubital tunnel outlet, and 5.5mm 2 (95% CI, 4.7–6.3mm 2 ) at the forearm level. The sensitivities, specificities, and diagnostic odds ratios pooled from 5 studies, using 10mm 2 as the cutoff point, were .85 (95% CI, .78–.90), .91 (95% CI, .86–.94), and 53.96 (95% CI, 14.84–196.14), respectively. Conclusions The ulnar nerve CSA measured by ultrasound imaging is useful for the diagnosis of CuTS and is most significantly different between patients and participants without CuTS at the medial epicondyle. Because the ulnar nerve CSA in healthy participants, at various locations, rarely exceeds 10mm 2 , this value can be considered as a cutoff point for diagnosing ulnar nerve entrapment at the elbow region.

Submuscular transposition (SMT) for treatment of ulnar nerve entrapment is commonly performed, however published comparisons of surgical techniques exclude a high proportion of the at-risk population encountered in real world practice. To examine the influence of risk factors on the clinical outcome following SMT we performed a retrospective review of all patients who underwent SMT, including patient self-reported outcome and Louisiana State University Medical Centre ulnar nerve grading scale. A total of 403 ulnar nerves were operated, with follow-up data available for 385 cases (359 patients). Risk factors (including smoking, diabetes, previous elbow trauma/pathology, subluxation, workers’ compensation) were reported in 266 of 385 surgeries (69.09%). SMT was the primary procedure in 339 nerves (88.05%), revision procedure in 46 nerves (11.95%). At last follow up 91.05% reported symptomatic improvement. Nerve grade improvement in 71.09% of primary and 67.39% revision surgery (p = 0.605). No significant difference in improvement was identified between demographic and risk categories, except for patient reported improvement in those without peripheral neuropathy (90.59% vs 73.33%, p = 0.027), and those not improved were on average older than those improved (62.94 vs. 55.68 years, p = 0.012). Superficial infection occurred in 2.6% and there were no deep infections. Application of published exclusion criteria would have resulted in exclusion of ½–⅔ of our cohort. SMT in patients with a history of elbow trauma, diabetes, workers compensation, smoking history, nerve subluxation or revision surgery have similar outcomes compared to those without these factors, whilst improved results were observed in younger patients and those without peripheral neuropathy.

Carpal tunnel syndrome and ulnar nerve compression at the elbow (e.g., cubital tunnel syndrome) are the most common upper extremity compressive neuropa- thies treated by hand surgeons. The aim of this study was to determine demographic factors and comorbidities that can help predict those patients most likely to undergo concurrent release of both the carpal tunnel and ulnar nerve at the elbow. We hypothesized that certain comorbidities, such as diabetes, would be associated with an increased risk for the necessity of concomitant procedures.Using Truven Marketscan® database, all patients who underwent carpal tunnel release were identified from 2010 to 2017 using Current Procedural Terminology (CPT) codes. Patients were only included if they had continuous enrollment in the database for 12 months preoperatively. Preoperative comorbidities and concurrent procedures were collected us- ing CPT and ICD-9 and 10 codes. Patients who underwent simultaneous carpal tunnel and ulnar nerve at the elbow release on the same day were compared to those patients who underwent carpal tunnel release alone. Additionally, patients who underwent either procedure initially and then went on to have the other procedure at a later date were compared. Univariate analysis and binomial logistic regression were performed to assess the contribution of patient demographics and comorbidities on the necessity of simultaneous release.259,574 patients underwent carpal tunnel release surgery and were included in the study. 24,401 (7.9%) of pa- tients also underwent simultaneous ulnar nerve release at the elbow on the same day. Significant risk factors associated with the need for simultaneous release, were male gender [(Odds Ratio (OR): 2.05, Confidence Interval (CI): 2.00-2.11, p0.001)], chronic pain (OR: 1.78, CI: 1.68-1.87, p0.001), diabetes (OR: 1.29, CI: 1.25-1.33, p0.001), history of al- coholism (OR: 1.23, CI: 1.10-1.38, p0.001), chronic renal disease (OR: 1.26, CI: 1.18-1.34, p0.001), tobacco use (OR: 1.49, CI: 1.42-1.56, p0.001), and patients with congestive heart failure (OR: 1.26, CI: 1.17-1.35, p0.001). Patients with consumer driven health plans and high deductible health plans (HDHP) were 1.5 times more likely to have simultane- ous release compared to those with comprehensive plans (OR: 1.46, CI: 1.37-1.56, p0.001; OR: 1.45, CI: 1.34-1.57, p0.001; respectively). For necessity of subsequent carpal or ulnar nerve release after either primary procedure, patients with a minimum of 3 years enrollment in the database were analyzed. Of the 113,505 patients who underwent initial carpal tunnel release, 1,746 (1.5%) went on to undergo release of the ulnar nerve at the elbow. Of the 12,673 patients who had initial ulnar nerve releases at the elbow, 721 (5.7%) required additional release of the carpal tunnel.Identification of patient demographic factors and comorbidities that can help predict the likelihood of si- multaneous release of both the carpal tunnel and ulnar nerve at the elbow can help direct management of these patients. Combining the two procedures can help save resources, minimize patient burden, and help reduce excess health care utilization.
