The article presents author's comments on the medial femoral condyle (MFC) bone graft for scaphoid nonunion, osteonecrosis, and failed surgery. It focuses on the patients with a nonunion of the scaphoid with a proximal fracture line, osteonecrosis and unsuccessful attempt in achieving surgical union. It focuses on nonoperative treatment, with the expectation that a salvage procedure to relieve pain and maintain motion.

Purpose To compare the tensile properties of 4-strand modified Kessler flexor tendon repairs using a looped or single-stranded suture. Methods We evaluated the mechanical properties of 4-strand Kessler zone II core suture repairs using either looped or single-stranded suture in human flexor digitorum profundus and flexor pollicis longus tendons. Forty repairs were performed on tendons from bilateral cadaveric hands: 20 matched tendons were divided into equal groups of 3-0 looped and 3-0 single-strand repairs and 20 additional matched tendons were divided into equal groups of 4-0 looped and 4-0 single-strand repairs. Repaired tendons were tested in uniaxial tension to failure to determine mechanical properties and failure modes. Data were analyzed to determine the effect of repair type (ie, looped vs single-stranded) for each suture caliber (ie, 3-0 and 4-0). Results Single-strand repairs with 3-0 suture demonstrated a significantly greater maximum load to failure and a significantly higher force at 2-mm gap compared with repairs with looped 3-0 suture. All 8 looped repairs with 3-0 suture failed by suture pullout whereas 7 of 8 repairs with 3-0 single-stranded suture failed by suture breakage. The mechanical properties of looped versus single-stranded repairs with 4-0 caliber suture were not statistically different. Repairs with 4-0 caliber suture failed by suture breakage in 8 of 10 single-strand repairs and failed by suture pullout in 6 of 10 repairs with looped suture. Conclusions In a time-0 ex vivo human cadaveric core suture model, the mechanical properties of a 4-strand repair using 3-0 single-stranded suture were significantly better than the same 4-strand repair performed with looped suture. Clinical relevance Four-strand flexor tendon repairs with 3-0 suture are mechanically superior when performed with single-strand suture versus looped suture. [ABSTRACT FROM AUTHOR]

Background: Although cubital tunnel syndrome is the second most common peripheral mononeuropathy (after carpal tunnel syndrome) encountered in clinical practice, its prevalence in the population is unknown. The objective of this study was to evaluate the prevalence of cubital tunnel syndrome in the general population.Methods: We surveyed a cohort of adult residents of the St. Louis metropolitan area to assess for the severity and localization of hand symptoms using the Boston Carpal Tunnel Questionnaire Symptom Severity Scale (BCTQ-SSS) and the Katz hand diagram. We identified subjects who met our case definitions for cubital tunnel syndrome and carpal tunnel syndrome: self-reported hand symptoms associated with a BCTQ-SSS score of >2 and localization of symptoms to the ulnar nerve or median nerve distributions.Results: Of 1,001 individuals who participated in the cross-sectional survey, 75% were women and 79% of the cohort was white; the mean age (and standard deviation) was 46 ± 15.7 years. Using a more sensitive case definition (lax criteria), we identified 59 subjects (5.9%) with cubital tunnel syndrome and 68 subjects (6.8%) with carpal tunnel syndrome. Using a more specific case definition (strict criteria), we identified 18 subjects (1.8%) with cubital tunnel syndrome and 27 subjects (2.7%) with carpal tunnel syndrome.Conclusions: The prevalence of cubital tunnel syndrome in the general population may be higher than that reported previously. When compared with previous estimates of disease burden, the active surveillance technique used in this study may account for the higher reported prevalence. This finding suggests that a proportion of symptomatic subjects may not self-identify and may not seek medical treatment.Clinical Relevance: This baseline estimate of prevalence for cubital tunnel syndrome provides a valuable reference for future diagnostic and prognostic study research and for the development of clinical practice guidelines.

An abstract of the article ''Educating Medical Students in Musculoskeletal Surgery and Medicine--How to Get a Course Up and Running at Your Institution," by Charles S. Day, Joseph Bernstein, and Martin I. Boyer is presented.

Background: Prior studies have suggested that patient-rated hand function is impacted by depression and pain catastrophization. We studied the impact that these comorbidities have on treatment outcomes. Methods: Two hundred and fifty-six patients presenting to an orthopaedic hand clinic were followed in this prospective cohort investigation. Patients who were prescribed treatment for atraumatic hand/wrist conditions were eligible for inclusion. At enrollment, all patients completed the Center for Epidemiologic Studies Depression (CES-D) scale, the Pain Catastrophizing Scale (PCS), and the Michigan Hand Outcomes Questionnaire (MHQ; scale of 0 to 100, with 100 indicating the best hand performance). One month and three months after treatment, patients again completed the MHQ. Participants' psychological comorbidity status was categorized as either affected (a CES-D score of ⩾16, indicating depression, or a PCS score of ⩾30, indicating catastrophization) or unaffected (a CES-D score of <16 and a PCS score of <30). Diagnoses and treatments for both the affected and unaffected groups were examined. The effect of time and patient status, and their interaction, on MHQ scores was evaluated by mixed modeling. Results: Fifty patients were categorized as affected and 206 as unaffected. Diagnoses and treatments differed minimally between the two groups. At the time of enrollment, themeanMHQ score of the unaffected group (64.9; 95% confidence interval [CI], 62.5 to 67.3) was significantly higher than that of the affected group (48.1; 95% CI, 43.3 to 53.0). Both groups demonstrated similar significant absolute improvement over baseline at three months after treatment (an increase of 12.5 points [95% CI, 7.5 to 17.4] in the affected group and 12.8 points [95% CI, 10.4 to 15.3] in the unaffected group). Thus, at the time of final follow-up, the rating of hand function by the affected patients (60.6 [95% CI, 55.0 to 66.2]) was still significantly poorer than the rating by the unaffected patients (77.7 [95% CI, 75.0 to 80.5]). Conclusions: Although patients affected by depression and/or pain catastrophization reported worse self-rated hand function at baseline and at the time of follow-up, these patients showed similar absolute improvement in self-rated hand function following treatment compared with patients with unaffected status.

The article presents the American Academy of Orthopaedic Surgeons (AAOS) recommended guidelines on the clinical practice of treating distal radius fractures. It says that the AAOS can not recommend against or in support of several clinical practices including nerve decompression, casting as treatment of unstable fractures, and operative treatment of patients aged 55 years and above. However, they suggest fracture operative fixation and rigid immobilization and recommends radiographic evaluation.

Background: Over 60% of patients with carpal tunnel syndrome present with symptoms and findings of nerve compression in both hands. Our goal was to compare patient-rated difficulties in performing activities of daily living in the early postoperative period between those undergoing bilateral carpal tunnel release and those undergoing unilateral carpal tunnel release.Methods: This prospective cohort study enrolled consecutive patients with bilateral carpal tunnel syndrome undergoing bilateral carpal tunnel release (n = 47) or unilateral carpal tunnel release (n = 41). Patient function and disease severity were measured by an abbreviated form of the Disabilities of the Arm, Shoulder and Hand questionnaire, QuickDASH, and the Boston Carpal Tunnel Questionnaire at baseline, at postoperative visit 1 at a mean time (and standard deviation) of 10 ± 3 days, and at postoperative visit 2 at a mean time (and standard deviation) of 30 ± 6 days. Patients rated their difficulty in completing fifteen activities of daily living each day for the first postoperative week. Patients reported the factors that influenced their choice of surgery.Results: There was no difference in baseline function or disease severity between the two groups with regard to QuickDASH and the Boston Carpal Tunnel Questionnaire. Patients in both groups improved after carpal tunnel release with no difference between groups either at postoperative visit 1 for QuickDASH (p = 0.97) and the Boston Carpal Tunnel Questionnaire (p = 0.86) or at postoperative visit 2 for QuickDASH (p = 0.43) and the Boston Carpal Tunnel Questionnaire (p = 0.34). Patients undergoing bilateral carpal tunnel release had more difficulty only during postoperative days 1 to 2 in opening jars (p = 0.03), cooking (p = 0.008), and doing household chores (p = 0.02). Patients in the two groups did not differ (p > 0.05) in their abilities to perform activities of daily living necessary for personal hygiene or independence on any day during the first seven days following surgery with regard to using the bathroom, bathing, dressing, or eating. Although the most common reason why patients chose bilateral carpal tunnel release was to avoid two surgical procedures (42%), the most common reason why patients chose unilateral carpal tunnel release was concern for self-care (36%).Conclusions: Patients with bilateral carpal tunnel syndrome can anticipate more severe functional impairment during the first few postoperative days with bilateral carpal tunnel release compared with unilateral carpal tunnel release, but limitations beyond postoperative day 2 or 3 are similar for bilateral and unilateral carpal tunnel release.Level Of Evidence: Therapeutic Level II.

To improve the functional outcomes of intrasynovial tendon suture, prior experiments evaluated individual technical modifications used in the repair process. Few studies, however, have assessed the combinatorial effects of those suture modifications in an integrated biomechanical manner, including a sample size sufficient to make definitive observations on repair technique. Two hundred fifty-six flexor tendon repairs were performed in human cadavera, and biomechanical properties were determined. The effects of five factors for flexor tendon repair were tested: core suture caliber (4-0 or 3-0), number of sutures crossing the repair site (four- or eight-strand), core suture purchase (0.75 or 1.2 cm), peripheral suture caliber (6-0 or 5-0), and peripheral suture purchase (superficial or 2 mm). Significant factors affecting the properties of the repair were the number of core suture strands and the peripheral suture purchase. The least significant factors were core suture purchase and peripheral suture caliber. The choice of core suture caliber affected the properties of repair marginally. Based on these results, we recommend that surgeons continue to focus on multi-strand repair methods, as the properties of eight-strand repairs were far better than those of four-strand repairs. To resist gap formation and enhance repair strength, a peripheral suture with 2 mm purchase is also recommended. Finally, since core suture caliber affected some biomechanical properties, including the failure mode, a 3-0 suture could be considered, provided that future in vivo studies can confirm that gliding properties are not adversely influenced. © 2012 Orthopaedic Research Society.

Purpose: We performed a randomized controlled trial assessing patient-reported outcome measures following trapeziectomy with ligament reconstruction and tendon interposition (LRTI) or suture tape suspensionplasty (STS) for treatment of thumb carpometacarpal joint osteoarthritis., Methods: Patients undergoing surgery for thumb carpometacarpal joint osteoarthritis were prospectively randomized to LRTI or STS. Outcome measures were collected at 2 weeks, 4 weeks, 3 months, and 1 year and included visual analog scale pain, Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity, return to work/activity, range of motion, grip/pinch strength, and complications., Results: Thirty-one patients (32 thumbs) were randomized from 51 patients offered participation over two years. One-year follow-up was 97%. Both groups had a decrease in visual analog scale pain scores at all postoperative time points. The trajectory of postoperative Patient-Reported Outcomes Measurement Information System Upper Extremity scores was similar, and both groups achieved the meaningful clinically important difference for improvement in PROMIS Upper Extremity by three months. Grip strength was substantially increased in both groups at one year. Return to work/activity and surgical complications favored the LRTI group., Conclusions: Our study did not suggest any clinically relevant differences in the postoperative patient-reported outcome measures or objective clinical measurements between LRTI and STS, although LRTI patients had a faster return to work/activity and lower complication rates., Type of Study/level of Evidence: Therapeutic IIB., 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.

Purpose: Trapeziectomy with tendon reconstruction/suspensionplasty (TRS) is the most commonly performed surgical procedure in the United States for treatment of thumb carpometacarpal (CMC) osteoarthritis (OA). Trapeziectomy with suture tape suspensionplasty (STS) has been used recently at the study institution as an alternative surgical treatment option with perceived benefits of earlier return to function and reduced operative time. The purpose of this study was to compare patient outcomes following TRS versus STS for treatment of thumb CMC OA., Methods: All patients who underwent primary, isolated TRS or STS for treatment of thumb CMC OA between 1/1/2014 and 9/1/2020 were analyzed. We assessed demographics and preoperative and postoperative patient-rated outcome scores including Patient-reported outcomes measurement information system scores as well as pain outcomes, satisfaction, and appearance at a mean of 2.6 years after surgery (minimum 6 months). Time to return to work and activities was compared between groups. Bivariate statistics compared outcomes between groups., Results: Ninety-four patients were included in the final study cohort, of which 53 underwent TRS and 41 underwent STS. There were no differences in preoperative, postoperative, or final patient-rated outcome scores between groups. Patients reported high global and appearance satisfaction scores at final follow-up in both groups. Mean tourniquet time was 15 minutes (26%) shorter and return to work was on average 3 weeks faster for the STS group., Conclusions: There were no differences in postoperative patient-rated outcome scores between the STS and TRS groups. The STS group had a shorter surgical time and faster return-to-work after surgery., Type of Study/level of Evidence: Therapeutic III., (© 2023 The Authors.)

Metacarpal nonunion is a rare outcome of metacarpal injury, and little has been published about its management. Care typically includes open reduction and internal fixation with a possible bone graft, similar to the treatment of other nonunions. However, there is no literature guidance if traditional methods do not lead to union. To improve the treatment of these recalcitrant metacarpal diaphyseal nonunions, we proposed a new surgical technique using a "top hat" bone graft harvested from the iliac crest. The graft is carefully shaped to create a cancellous "crown," which is inserted into the nonunion site, and cortical "brims," which are used to secure the graft to the metacarpal. This has been successful in treating 2 cases of metacarpal nonunion that failed to heal with first-line intervention., (Copyright © 2022. Published by Elsevier Inc.)

Case: A 61-year-old woman presented with a failed proximal ulna allograft-prosthetic composite after revision total elbow arthroplasty (TEA). The ulnar deficiency was addressed using an osteomuscular flap from the distal radius pedicled on the radial artery. At final follow-up, she had minimal pain and a flexion-extension arc of 0° to 130°. Radiographs demonstrated graft incorporation and a stable TEA construct., Conclusion: This demonstrates utilization of a vascularized osteomuscular flap from the radius for treatment of proximal ulnar deficiency in the setting of revision TEA. This technique offers an alternative option for the challenge of a failed TEA with ulnar bone loss., 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/B784)., (Copyright © 2022 by The Journal of Bone and Joint Surgery, Incorporated.)

Mutilated upper limbs suffer loss of substance of various tissues with loss of prehension. The most important factor in salvage of a mutilated hand is involvement of a senior surgeon at the time of initial assessment and debridement. A regional block given on arrival helps through assessment and investigations in a pain-free state. Infection still remains the important negative determinant to outcome and is prevented by emergent radical debridement and early soft tissue cover. Radical debridement and secure skeletal stabilization must be achieved on day one in all situations. Dermal substitutes and negative pressure wound therapy are increasingly used but have not substituted regular soft tissue cover techniques. Ability to perform secondary procedures and the increased use of the reconstructed hand with time keeps reconstruction a better option than prosthesis fitting. Toe transfers and free functioning muscle transfers are the two major secondary procedures that have influenced outcomes.

Purpose: Enthusiasm for peripheral nerve transfers increased over the past several years, but further studies are still needed to establish the role of these procedures in peripheral nerve reconstruction. The primary goal of this study was to describe the frequency of nerve transfer surgery among newly trained orthopedic surgeons., Methods: We queried the American Board of Orthopaedic Surgery Part II case log database for all nerve reconstruction Current Procedural Terminology codes for examination years 2004 to 2018 for surgeries performed between 2003 and 2017. Information collected for each patient included examination year, year of surgery, surgeon fellowship training subspecialty, geographic region (as defined by the American Board of Orthopaedic Surgery Part II case log database), patient age, and patient sex., Results: A total of 3,359 nerve reconstruction cases were logged by 1,542 individual candidates from examination years 2004 to 2018. Of the nerve reconstruction codes, 2.1% were nerve transfer codes. There was a statistically significant increase in the proportion of nerve transfer codes over the study period, from 0% of nerve reconstruction codes in examination years 2004 to 2006 to 4.1% of nerve reconstruction codes in examination years 2016 to 2018 (Z = -6.82; P < .001)., Conclusions: There has been an increase in the number of nerve transfer procedures relative to all nerve reconstruction codes for peripheral nerve conditions., Clinical Relevance: There is a modest but significant increase in nerve transfer procedures over time among newly trained orthopedic surgeons, which suggests the need for long-term outcomes studies for nerve transfers procedures performed in the setting of peripheral nerve conditions., Competing Interests: Declaration of interests: No benefits in any form have been received or will be received by the authors related directly or indirectly to the subject of this article.

Giant cell tumor of the distal radius is a rare, locally destructive, and frequently recurrent tumor. We present a case of Campanacci Grade III giant cell tumor of the distal radius with pathologic fracture and cortical destruction which was treated with neoadjuvant denosumab. This facilitated en-bloc resection of the entire distal radius, including the articular surface, while minimizing tumor contamination. Reconstruction was accomplished using a vascularized ulnar transposition flap to facilitate radioulnoscapholunate fusion, which was fixated using a long-stem contralateral variable angle locking volar distal radius plate in a dorsal position. This case illustrates multidisciplinary management of a challenging reconstructive problem and demonstrates a novel strategy for fixation which repurposes familiar and readily available hardware to provide optimal osteosynthesis.

Targeted muscle reinnervation after upper-extremity amputation has demonstrated improved outcomes with myoelectric prosthesis function and postoperative neuropathic pain. This technique has been established in the setting of shoulder disarticulation as well as transhumeral and transradial amputations, but a detailed technique of targeted muscle reinnervation with free tissue transfer from the volar forearm after forequarter amputation has not yet been described. Here, we describe a technique using a volar forearm filet flap to achieve simultaneously satisfactory soft tissue coverage after resection of a tumor from the chest wall and targeted muscle reinnervation of the brachial plexus., (© 2020 The Authors.)

Purpose: Although volar plating of the distal radius is performed frequently, the necessity of distal bicortical fixation in the metaphyseal and epiphyseal areas of the distal radius has not been proven. This study aimed primarily to quantify the ability of unicortical distal screws to maintain operative reduction of adult distal radius fractures and secondarily to determine if unicortical screw lengths could be predicted based on anatomical measurements., Methods: This prospective trial enrolled 75 adult patients undergoing volar locking plate fixation of a unilateral distal radius fracture at a tertiary center. Study inclusion required screw fixation in the distal rows of the plate performed with unicortical screw placement. The primary outcome was maintenance of operative reduction, according to predefined parameters, quantified by comparing initial operative reduction to final reduction after fracture healing. Repeated measures analysis of variance analyzed for systematic change in radiographic parameters between injury, operative, and healed images. Correlation coefficients quantified the relationship of screw lengths with lunate width and other anatomical measurements., Results: Seventy-five patients (mean age, 54 years ± 15 years; 79% women) were enrolled and followed to fracture union. Fracture severity varied and included AO type A (40%), B (12%), and C (48%) fractures. There was no significant change in mean lateral translation, intra-articular gap, intra-articular stepoff, radial inclination, or lateral tilt of the radius between the time of fixation and union for the cohort. Two patients lost reduction (increased dorsal tilt, 10°, 20°, respectively), potentially attributable to provision of unicortical fixation (3%; 95% confidence interval [95% CI], 0%-9%). No extensor tenosynovitis or extensor tendon ruptures occurred. Eighty percent of screws were 18 mm or less and screw lengths were not correlated with lunate width or any other anatomical measurements., Conclusions: Unicortical distal fixation during volar locking plate fixation effectively maintains operative reductions of distal radius fractures while potentially minimizing the incidence of extensor tendon ruptures., Type of Study/level of Evidence: Therapeutic IV., (Copyright © 2018 American Society for Surgery of the Hand.

Purpose: Prescription opioid abuse is an epidemic in the United States; multimodal analgesia has been suggested as a potential solution to decrease postoperative opioid use. The primary aim of this study was to determine the effect of perioperative celecoxib on opioid intake. Secondary goals were to determine whether perioperative administration of celecoxib decreased postoperative patient-reported pain and whether patient demographic characteristics could predict postoperative pain and opioid intake., Methods: This prospective cohort study enrolled patients undergoing mass excision or carpal tunnel, trigger finger, or de Quervain release by 1 of 3 fellowship-trained hand surgeons. Patients in the experimental group were given 200 mg celecoxib tablets taken twice a day starting the day before surgery and continued for 5 days after surgery. Both groups received hydrocodone-acetaminophen tablets 5 mg/325 mg as needed after surgery. After surgery, patients completed daily opioid consumption and pain logs for 7 days and underwent a pill count. Outcomes included morphine milligram equivalents (MME) consumed and postoperative pain., Results: A total of 123 patients were enrolled: 68 control patients and 54 celecoxib patients. Fifty (74%) and 37 (69%) patients, respectively, completed the study. Overall, the median number of MMEs consumed was 25 (range, 0-330). During the first postoperative week, patients in the celecoxib and control groups were similar with respect to postoperative pain experienced (median visual analog scale score, 2.0 vs 1.4, respectively) and amount of opioid taken (median MMEs = 30 vs 20, respectively)., Conclusions: Patients taking perioperative celecoxib had similar postoperative pain and opioid intake compared with patients not prescribed celecoxib in the study. Regardless of study group, 4 to 10 hydrocodone tablets were sufficient to control postoperative pain for most patients undergoing soft tissue ambulatory hand surgery. This may be the result of the limited duration and mild nature of pain after outpatient elective hand surgery., Type of Study/level of Evidence: Therapeutic II., (Copyright © 2018 American Society for Surgery of the Hand.

Background: Trapeziometacarpal arthrodesis (TMA) has been complicated by nonunion and hardware failure., Questions/purposes: We hypothesized that modification of the TMA technique with a locking cage plate construct would afford reliable bony union while producing greater hand function than trapeziectomy with ligament reconstruction and tendon interposition (LRTI) at early follow-up., Methods: We enrolled 36 consecutive patients with trapeziometacapal osteoarthritis (14 TMA patients (15 thumbs), 22 LRTI patients (22 thumbs)). The study was powered to detect a minimal clinically important difference on the QuickDASH questionnaire between groups. Secondary outcomes included Michigan Hand Questionnaire (MHQ), VAS-pain, and EQ-5D-3L scores. Patients were examined to evaluate thumb motion and strength. TMA patients were evaluated clinically and radiographically for union., Results: Mean follow-up was 15.6 months, and the mean age was 59.2 years. Union was achieved in 14/15 (93%) of TMA thumbs. Improvement in QuickDASH scores was similar after TMA and LRTI (49 to 28 and 50 to 18, respectively). Postoperative patient-rated upper extremity function, health status, and pain were similar between groups. Pinch strength was significantly greater after TMA (5.9 vs 4.7 kg). No differences in thumb or wrist range of motion were observed postoperatively with the exception of greater total metacarpophalangeal joint motion after TMA. Complications after TMA included nonunion (7%), development of symptomatic scaphotrapezotrapezoidal (STT) arthrosis (7%), symptomatic hardware (7%), and superficial branch of the radial nerve (SBRN) paresthesia (7%). Complications after LRTI included subsidence (5%), MP hyperextension deformity (5%), and SBRN paresthesias (5%)., Conclusions: At early follow-up, patient-rated function was similar among patients undergoing TMA and LRTI. TMA produced 25% greater pinch strength compared with LRTI. Despite historical concerns regarding global loss of ROM with arthrodesis, motion was similar between groups. Our observed TMA nonunion rate of 7% is low relative to historically reported nonunion rates (7-16%). Locking cage plate technology affords rigid fixation for TMA with promising early results noting reliable bony union while minimizing complications., Competing Interests: Nikolas H.

Background: Double crush syndrome, the association between proximal and distal nerve lesions, has been established. This investigation compares the outcomes of nerve surgery in patients with isolated peripheral compression versus those with double crush syndrome treated with peripheral nerve and cervical spine operations., Methods: This case-controlled study enrolled 80 patients: 40 underwent carpal or cubital tunnel surgery and cervical spine surgery (double crush group); and 40 controls, matched by age and sex, underwent only peripheral nerve decompression (peripheral nerve group). A minimum of 18 months was required after peripheral nerve and cervical spine surgery for office assessment (mean, 4.9 years and 6.0 years, respectively). Statistical analysis compared postoperative function and symptom severity questionnaires, physical examination, and patient-reported satisfaction between groups., Results: Patients in the double crush group reported significantly more disability and persistent symptoms on the QuickDASH questionnaire (29 versus 13) and Levine Katz symptom severity (2.0 versus 1.4) and functional status scales (1.9 versus 1.4). Double crush patients reported significantly lower satisfaction. The double crush group exhibited a greater frequency of persistent signs of nerve irritability and muscle weakness compared with the control group., Conclusions: At a minimum of 18 months after peripheral nerve surgery, patients with a history of cervical spine surgery are likely to have inferior patient-reported outcomes, persistent nerve dysfunction, and lower satisfaction after peripheral nerve release compared with patients following isolated peripheral nerve surgery. Double crush syndrome was associated with poorer outcome after peripheral nerve surgery despite treatment of cervical spine nerve compression., Clinical Question/level of Evidence: Therapeutic, III.

Orthopedic surgery lacks racial and sexual diversity, which we hypothesized stems from absence of exposure to orthopedics during medical school. We conducted a study to determine whether diversity of matched orthopedic surgery residency applicants increased after introduction of a required third-year rotation. We compared 2 groups: precurriculum and postcurriculum. The postcurriculum group was exposed to a required 1-month musculoskeletal rotation during the third year of medical school. Comparisons were made of percentage of total students exposed to orthopedics, percentage who applied to and matched to orthopedic surgery, and proportion of women and underrepresented minorities. A prospective survey was used to determine when students chose orthopedics and what influenced their decisions. The required rotation increased the percentage of third-year students rotating on orthopedics (25%) with no change in application rate (6%). It also led to an 81% relative increase in the proportion of female applicants and a 101% relative increase in underrepresented minority applicants. According to survey data, 79% of students chose orthopedics during their third year, and 88% thought they were influenced by their rotation. A required third-year rotation exposes more medical students to orthopedics and increases the diversity of matching students.

Purpose: To determine the impact of uninterrupted use of warfarin on hand and wrist surgery., Methods: This single-center, prospective cohort trial enrolled adult patients undergoing hand and wrist surgery. Between May 2009 and August 2014, 47 surgical patients receiving uninterrupted warfarin (50 procedures) were enrolled and matched as a group by age and procedure type to 48 surgical patients (50 procedures) who were not prescribed warfarin. Complications, defined as bleeding, infection, or wound dehiscence requiring reoperation, were recorded for each group. Surgical outcome measures were composed of objective findings affected by surgical site bleeding (ie, ecchymosis extent, hematoma presence, 2-point discrimination) and standardized patient-rated assessments (Quick-Disabilities of the Arm, Shoulder, and Hand, and visual analog scales: pain and swelling). We collected data preoperatively and at 2 and 4 weeks postoperatively. Statistical analyses contrasted complications and outcomes data between patient groups., Results: One procedure (2%; 95% confidence interval, 0% to 11%) in a patient taking warfarin was complicated by hematoma requiring reoperation resulting from an elevated postoperative international normalized ratio of 5.4. There were no complications among controls (0%; 95% confidence interval, 0% to 7%). At 2 weeks postoperatively, patients receiving warfarin more frequently had hematomas (28% vs 10%) and demonstrated a greater extent of ecchymosis from the surgical incision (50 vs 19 mm). At 4 weeks, no differences existed in hematoma presence or extent of ecchymosis between groups. The incidence of transiently elevated 2-point discrimination was not different between groups (10% warfarin; 6% controls). Visual analog scores for pain and swelling were not significantly different between groups at any time. Differences in Quick-Disabilities of the Arm, Shoulder, and Hand scores between groups did not exceed a minimal clinically important difference., Conclusions: Uninterrupted use of warfarin in patients undergoing surgery of the hand and wrist was associated with an infrequent risk of bleeding complication requiring reoperation. Increased rates of hematoma and ecchymosis in patients taking warfarin normalized by 4 weeks postoperatively., Type of Study/level of Evidence: Therapeutic II., (Copyright © 2015 American Society for Surgery of the Hand.

Purpose: To determine whether vibratory stimulation would decrease pain experienced by patients during corticosteroid injection for trigger finger., Methods: A total of 90 trigger finger injections were randomized to 1 of 3 cohorts. With the injection, patients received no vibration (control group), ultrasound vibration (sham control group), or vibration (experimental group). We used a commercial handheld massaging device to provide a vibratory stimulus for the experimental group. We obtained visual analog scale (VAS) pain scores before and after injection to assess anticipated pain and actual pain experienced., Results: Anticipated pain and actual pain did not differ significantly among groups. Anticipated VAS pain scores were 45, 48, and 50 and actual VAS pain scores were 56, 56, and 63 for the vibration, control, and sham control groups, respectively. When normalized using anchoring VAS pain scores for "stubbing a toe" or "paper cut," no between-group differences remained in injection pain scores., Conclusions: Concomitant vibratory stimulation does not reduce pain experienced during corticosteroid injections for trigger finger., Type of Study/level of Evidence: Therapeutic I., (Copyright © 2014 American Society for Surgery of the Hand.

Purpose: To quantify diabetic patients' change in blood glucose levels after corticosteroid injection for common hand diseases and to assess which patient-level risk factors may predict an increase in blood glucose levels., Methods: Patients were recruited for this case-crossover study in the clinic of fellowship-trained hand surgeons at a tertiary care center. Patients with diabetes mellitus type 1 or 2, who received a corticosteroid injection, recorded the morning fasting blood glucose levels for 14 days after the injection. Fasting glucose levels on days 1 to 7 after injection qualified as case data; levels on days 10 to 14 provided control data. A mixed model with a priori contrasts was used to compare postinjection blood glucose levels with baseline levels. We used a linear regression model to determine patient predictors of a postinjection rise in blood glucose levels., Results: Of 67 patients recruited for the study returned, 40 (60%) completed blood glucose logs. There was a significant increase in fasting blood glucose levels after injection limited to postinjection days 1 and 2. Among patient risk factors in the linear regression model, type 1 diabetes and use of insulin each predicted a postinjection increase in blood glucose levels from baseline, whereas higher glycated hemoglobin levels did not predict increases., Conclusions: Corticosteroid injections in the hand transiently increase blood glucose levels in diabetic patients. Patients with type 1 diabetes and insulin-dependent diabetics are more likely to experience this transient rise in blood glucose levels., Type of Study/level of Evidence: Therapeutic III., (Copyright © 2014 American Society for Surgery of the Hand.

There are many options for nonmicrosurgical soft tissue coverage of hand wounds, ranging from split thickness skin grafting to pedicled soft tissue transfer, depending on the size, location, blood supply, and depth of the wound. Although many of these techniques have been available for decades, recent advancements in wound management include synthetic dermal substitution, new dressing materials, and variations on previously described or novel pedicled flaps.The goals of coverage include maximizing healing, function, aesthetic appearance, and patient satisfaction, while minimizing donor site morbidity. Optimal management often relies on an individual surgeon's assessment and judgment, as hand wounds can vary greatly and pose unique challenges, and multiple coverage options often exist for each wound. Here, we aim to present useful and up-to-date information on nonmicrosurgical soft tissue coverage for hand reconstruction focusing on recent findings of interest to provide an update on areas with evolving evidence.

Purpose: To compare the tensile properties of a 3-0, 4-strand flexor tendon repair with a 4-0, 4-strand repair and a 4-0, 8-strand repair., Methods: Following evaluation of the intrinsic material properties of the 2 core suture calibers most commonly used in tendon repair (3-0 and 4-0), we tested the mechanical properties of 40 cadaver flexor digitorum profundus tendons after zone II repair with 1 of 3 techniques: a 3-0, 4-strand core repair, a 4-0, 8-strand repair, or a 4-0, 4-strand repair. We compared results across suture caliber for the 2 sutures and across tendon repair methods., Results: Maximum load to failure of 3-0 polyfilament caprolactam suture was 49% greater than that of 4-0 polyfilament caprolactam suture. The cross-sectional area of 3-0 polyfilament caprolactam was 42% greater than that of 4-0 polyfilament caprolactam. The 4-0, 8-strand repair produced greater maximum load to failure when compared with the 2 4-strand techniques. Load at 2-mm gap, stiffness, and work to yield were significantly greater in the 4-0, 8-strand repair than in the 3-0, 4-strand repair., Conclusions: In an ex vivo model, an 8-strand repair using 4-0 suture was 43% stronger than a 4-strand repair using 3-0 suture, despite the finding that 3-0 polyfilament caprolactam was 49% stronger than 4-0 polyfilament caprolactam. These results suggest that, although larger-caliber suture has superior tensile properties, the number of core suture strands across a repair site has an important effect on time zero, ex vivo flexor tendon repair strength., Clinical Relevance: Surgeons should consider using techniques that prioritize multistrand core suture repair over an increase in suture caliber., (Copyright © 2014 American Society for Surgery of the Hand.

Purpose: To quantify the performance of the verbally administered Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire by assessing its replication of self-administered scores, its test-retest reliability, and its rate of scorable completion compared with its self-administered, written administration., Methods: Fifty patients presenting for initial visits to a hand clinic were enrolled regardless of diagnosis. All patients completed a written and a verbal QuickDASH 1 day apart (25 patients written first; 25 patients verbal first). Intraclass correlation coefficients quantified the verbal questionnaire's ability to reproduce written scores. Participants verbally completed the questionnaire a final time, 5 months later, to assess test-retest reliability. To quantify the usability of survey data, we compared percentages of scorable surveys between written and verbally administered QuickDASH questionnaires in this study and in prior studies within our division., Results: The intraclass correlation coefficient between the 2 QuickDASH administration types for the entire sample was 0.91. Across all participants, there was a minimal change in mean score from a patient's written QuickDASH to that patient's first verbal QuickDASH score. Scoring consistency between QuickDASH administrations was similar for each administration sequence (phone followed by written vs. written followed by phone) and by diagnosis. Test-retest reliability between the 2 verbal administrations demonstrated good reliability and a minimal difference between scores. In this study, no written or verbal surveys were incomplete. Reviewing our practice, 17% of 258 written questionnaires produced unscorable data compared with 0% of 239 verbally administered surveys., Conclusions: Our results indicate that verbal administration of the QuickDASH replicates clinically relevant scores of the written QuickDASH, has good test-retest performance, and may minimize unusable data. These data allow researchers greater flexibility in gathering patient outcome data in both retrospective and prospective studies., Type of Study/level of Evidence: Diagnostic II., (Copyright © 2014 American Society for Surgery of the Hand.

Purpose: To determine whether symptomatic dorsal wrist ganglions are associated with generalized ligamentous hyperlaxity., Methods: Ninety-six patients (61 females) presenting to hand surgeons for a symptomatic dorsal wrist ganglions were prospectively enrolled in this case-control investigation. Beighton scores were calculated to quantify generalized ligamentous laxity in each patient, and a scaphoid shift test (scapholunate capsuloligamentous laxity evaluation) was performed. A positive scaphoid shift test was defined by both pain and a palpable clunk. Ninety-six individuals without ganglions were then enrolled to form an age and sex frequency-matched control cohort. The control group was similarly assessed for Beighton score and scaphoid shift test. Binary logistical regression was performed to assess the association of ganglions with generalized ligamentous hyperlaxity (Beighton score ≥ 4) while accounting for effects of age and sex., Results: Patients with symptomatic dorsal wrist ganglions demonstrated significantly increased rates of generalized ligamentous hyperlaxity. Among those with ganglions, 27 of 96 (28%) patients exhibited generalized ligamentous hyperlaxity, compared with 12 of the 96 (13%) age- and sex-matched individuals in the control group. Patients with symptomatic dorsal wrist ganglions were also significantly more likely to demonstrate localized scapholunate hyperlaxity with a positive scaphoid shift test (25% positive scaphoid shift test with ganglions vs 1% in controls). In logistical modeling, patients with dorsal wrist ganglions had 2.9 (95% confidence interval [CI] 1.3-6.2) times greater odds of generalized ligamentous hyperlaxity compared with patients without a dorsal wrist ganglion after accounting for patient age and sex., Conclusions: Symptomatic dorsal wrist ganglions were associated with both generalized ligamentous hyperlaxity and a positive scaphoid shift test. Although an association between wrist ganglions and ligamentous hyperlaxity does not prove causation, the possibility of the same underlying pathological entity causing both can be envisioned (ie, abnormal formation or organization of dense regular connective tissue)., Type of Study/level of Evidence: Prognostic III., (Copyright © 2013 American Society for Surgery of the Hand.

Purpose: To quantify the impact of maintaining antiplatelet medication during hand and wrist surgery on bleeding and functional outcomes., Methods: This prospective cohort trial compared operative outcomes and complications of hand and wrist surgery in patients without interruption of daily antiplatelet medications (n = 107 procedures) with control patients (n = 107 procedures). We determined rates of complications requiring reoperation for each group. We compared measures of surgical site bleeding (extent of ecchymosis or hematoma formation), patient-rated outcome assessment (Quick Disabilities of the Arm, Shoulder, and Hand score and visual analog scales of pain and swelling), and 2-point discrimination between groups. Data were collected preoperatively and postoperatively at 2 and 4 weeks. We confirmed control and antiplatelet populations to be similar for data analysis according to health status (Short Form-12) and percentage of bony procedures., Results: One patient receiving antiplatelet medication required reoperation for surgical site bleeding after wrist arthrodesis (0.9%). There were no complications in the control group. The extent of postoperative ecchymosis was similar in the antiplatelet and control patients at 2 weeks (16 vs 19 mm) and 4 weeks (1 vs 1 mm). Hematoma rates were not increased for patients receiving antiplatelet medication (17% vs 14% at 2 wk). Patient-rated function scores were equivalent at baseline and at follow-up between groups. A total of 22 control patients and 20 patients receiving antiplatelet medication had transiently increased 2-point discrimination (≥ 2-mm change) postoperatively., Conclusions: Bleeding-related perioperative complications were rare when continuing antiplatelet medications without interruption for hand and wrist surgery. Maintenance of antiplatelet medication does not appear to negatively affect patient-rated or objective measures of function, although surgical-site bleeding may be greatest in patients taking higher-dose antiplatelet medication and undergoing bony procedures., Type of Study/level of Evidence: Therapeutic II., (Copyright © 2013 American Society for Surgery of the Hand.

In this article, a group of international leaders in tendon surgery of the hand provide details of their current methods of primary flexor tendon repair. They are from recognized hand centers around the world, from which major contributions to the development of methods for flexor tendon repair have come over the past 2 decades. Changes made since the early 1990s regarding surgical methods and postoperative care for the flexor tendon repair are also discussed. Current practice methods used in the leading hand centers are summarized, and key points in providing the best possible clinical outcomes are outlined., (Copyright © 2013 Elsevier Inc.

Purpose: Previous studies have identified the association between trigger digit and carpal tunnel syndrome (CTS). However, whether the presence of multiple trigger digits affects the prevalence of CTS is unknown. The purpose of this study was to determine the incidence of carpal tunnel symptoms in patients treated for single versus multiple trigger digits., Methods: We performed a retrospective review of 300 patients treated for trigger digit by injection or surgical release and recorded CTS symptoms, signs, and treatment for either the ipsilateral or contralateral hand documented within 24 months before trigger digit treatment and for an average of 35 months (range, 7- 66 mo) after treatment. Patients were categorized as having single (n = 160) or multiple (n = 140) trigger digits. Binary logistic regression modeled risk factors for development of CTS. Patient age, sex, number of trigger digits (single or multiple), and presence of diabetes, gout, thyroid disease, or thumb osteoarthritis were considered independent variables., Results: A total of 58 of 140 patients (41%) who presented with multiple trigger digits exhibited concomitant carpal tunnel symptoms, compared with 26 of 160 (16%) patients who presented with a single trigger digit. Significant independent predictors of CTS associated with trigger digits in the final regression model included multiple trigger digits (odds ratio = 3.6; subjects with multiple trigger digits had significantly higher odds of carpal tunnel presentation than subjects with a single trigger digit) and diabetes (odds ratio = 1.9; diabetic subjects had significantly higher odds of carpal tunnel presentation than nondiabetics)., Conclusions: A greater than 3-fold increase in the relative risk of CTS development exists in patients undergoing treatment for multiple trigger digits, compared with those undergoing treatment for a single trigger digit. Awareness of this association may aid in the early diagnosis and treatment of CTS in patients presenting with multiple trigger digits., Type of Study/level of Evidence: Prognostic III., (Copyright © 2013 American Society for Surgery of the Hand.

We conducted this study to evaluate the hypothesis that the need for a higher level of care is the most important reason for the transfer of patients with hand trauma to a level I trauma center. We prospectively assessed 53 patients transferred to our level I trauma center for evaluation of an acute hand injury. Specialty of referring physician, case complexity as assessed with visual analog scale, and patient insurance status were obtained before transfer and were reassessed after arrival. Only 9 patients were examined by a surgeon before transfer. On the basis of injury severity, we judged that 40 of the 53 patients required the immediate care of a hand surgeon but that only 13 required the resources of a level I trauma center. Most of the patients were transferred without prior evaluation by a hand surgeon, despite there being an on-staff surgeon at many of the hospitals.

The clinical practice guideline is based on a systematic review of published studies on the treatment of distal radius fractures in adults. None of the 29 recommendations made by the work group was graded as strong; most are graded as inconclusive or consensus; seven are graded as weak. The remaining five moderate-strength recommendations include surgical fixation, rather than cast fixation, for fractures with postreduction radial shortening >3 mm, dorsal tilt >10 degrees , or intra-articular displacement or step-off >2 mm; use of rigid immobilization rather than removable splints for nonsurgical treatment; making a postreduction true lateral radiograph of the carpus to assess dorsal radial ulnar joint alignment; beginning early wrist motion following stable fixation; and recommending adjuvant treatment with vitamin C to prevent disproportionate pain.

Objective: The purpose of this study was to analyze the sonographic appearance of a large series of pathologically proven ganglia., Materials and Methods: A computer search of sonography and pathology reports for hand and wrist ganglia was performed. All sonography reports and images were reviewed for ganglion size, location, presence of a neck, echogenicity, acoustic enhancement, locules, color Doppler flow, margins, wall thickness, and calcifications and to determine if the ganglion was palpable or collapsed. All pathology reports were reviewed for histologic features that were then correlated with the sonographic images. Ganglia were categorized into three groups: simple, complex cystic, and solid-appearing., Results: Of 60 ganglia, 34 were complex, 91% of which were located within the dorsal or volar wrist; 97% had well-defined margins; 76%, locules; 68%, acoustic enhancement; 47%, a thick wall; 15%, internal reflectors; and 12%, blood flow. Of the 23 simple ganglia, 11 involved the extensor or flexor tendon sheath, 73% of which were simple. Complex ganglia had a larger mean volume than simple. Three ganglia were solid-appearing. A visible neck was seen in 25% of ganglia., Conclusion: Most ganglia are complex rather than simple on sonography. Complex ganglia are larger than simple ganglia; located within the dorsal or volar wrist; and usually have well-defined margins, thick walls, locules, and acoustic enhancement. A small percentage have blood flow and internal reflectors. Simple ganglia are smaller and can occur within the volar or dorsal wrist, or flexor tendon sheath. Most flexor tendon sheath ganglia are simple rather than complex. Solid-appearing ganglia, although unusual, may mimic a benign neoplasm or synovitis.

Purpose: To evaluate the timing of improvement after extra-articular steroid injection, the incidence of a postinjection pain flare (a delayed postinjection transient increase in pain), and the role of the injection acidity in the postinjection flare., Methods: One hundred twenty-five patients with trigger finger (88 patients) or de Quervain's tenosynovitis (37 patients) were prospectively randomized in this double-blind study to receive either an injection of steroid, lidocaine, and bupivacaine alone (standard injection, acidic pH) or an injection of steroid, lidocaine, bupivacaine, and bicarbonate (balanced injection, neutral pH). All patients completed a visual analog scale for pain before and immediately after the injection, daily for 7 days, and then again at 6 weeks. A flare reaction was defined as an increase in the visual analog scale score by 2 or more points any time after the injection., Results: All patients immediately responded to the steroid injection, but pain rebounded to preinjection levels by day 1. In both groups the pain then gradually declined over the course of 7 days. In the balanced group, 23 of the 68 patients had flare reactions. In the standard group, 18 of the 57 patients had flare reactions. The difference between groups was not significant., Conclusions: Patients respond to extra-articular steroid injections with gradual improvement over the course of the first week. An increase in pain, or flare reaction, in the days following a steroid injection was noted in 33% of patients. A pH-balanced injection did not significantly decrease the risk of a flare reaction., Type of Study/level of Evidence: Therapeutic I.

Purpose: To explore the course of the radial nerve in the brachium and to identify practical anatomic landmarks that can be used to avoid iatrogenic injury during humerus fracture fixation., Methods: Data were collected from 27 adult cadaveric specimens, including 18 embalmed cadavers and 9 fresh-frozen limbs. Measurements were taken using osseous landmarks to define the relationship of the radial nerve and the posterior and lateral humerus. The extremities were studied further to determine the association of the radial nerve and anatomic landmarks on both longitudinal and cross-sectioned specimens., Results: A 6.3 cm +/- 1.7 segment of radial nerve was found to be in direct contact with the posterior humerus from 17.1 cm +/- 1.6 to 10.9 cm +/- 1.5 proximal to the central aspect of the lateral epicondyle, centered within 0.1 cm +/- 0.2 of the level of the most distal aspect of the deltoid tuberosity. The radial nerve lay in direct contact with the periosteum in all specimens, without evidence of a structural groove in the humerus in any specimen. On entering the anterior compartment, the radial nerve had very little mobility as it was interposed between the obliquely oriented lateral intermuscular septum and the lateral aspect of the humerus. As it extended distally, the nerve coursed anterior to the humerus and became protected by brachialis muscle at the level of the proximal aspect of the lateral metaphyseal flare., Conclusions: The radial nerve is at risk of injury with fractures of the humerus and with subsequent operative fixation in 2 areas. The first is along the posterior midshaft region for a distance of 6.3 cm +/- 1.7 centered at the distal aspect of the deltoid tuberosity. The second is along the lateral aspect of the humerus in its distal third from 10.9 cm +/- 1.5 proximal to the lateral epicondyle to the level of the proximal aspect of the metaphyseal flare. The deltoid tuberosity is a consistent and practical anatomic landmark that can be used to determine the level of the radial nerve along the posterior aspect of the humerus during operative fixation from an anterior approach.

Sound peer-reviewed data on the surgical treatment of distal radius fractures, in terms of patients' functional outcome, ability to return to work, complications, and radiographic results, are few. At present, treatment of distal radius fractures is focused on the restoration of articular alignment, radial length, and volar inclination of the articular surface. Early diagnosis and treatment of fracture complications, such as type II complex regional pain syndrome, is encouraged based on published peer-reviewed data.

The complex anatomy of the hand means that injuries result in substantial loss of function. The damage must be repaired to regain the lost function. Fractures need to heal in anatomic position, and the soft tissues must be supple so that the fingers can move through a useful range of motion. Evaluation and management of malunion, nonunion, bone loss, and stiff fingers are important factors in posttraumatic reconstruction of the hand.

Compromised function of an epiphyseal plate caused by trauma, tumor, infection, or congenital malformation can result in significant musculoskeletal deformity. Techniques used to correct or minimize the extent of these deformities include autogenous or allogeneic cancellous bone grafts, nonvascularized cortical allografts, vascularized bone and composite tissue transfers, and distraction osteogenesis. These solutions are not ideal for children because they do not adequately address the actively growing nature of the extremity. Microvascular techniques have enabled the experimental transplantation of vascularized epiphyseal plates with high levels of postoperative viability and subsequent growth and offer a potential advantage over conventional treatments.

Purpose: To prospectively evaluate the subjective and objective functional outcome of patients treated with a pyrolytic carbon proximal interphalangeal (PIP) joint arthroplasty for posttraumatic arthritis., Methods: Five patients (7 joints) with traumatic injuries to the PIP joint were followed up for more than 1 year after pyrolytic carbon arthroplasty. All patients were treated with surgical reduction and stabilization at the time of the initial injury, but at a minimum of 6 months after the initial injury they had persistent pain, loss of motion, and functional limitations. All patients had a stable PIP joint with a satisfactory extensor mechanism but had radiographic evidence of posttraumatic arthritis. Patients were evaluated before and after arthroplasty with the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and visual analog scale and by radiographic and physical examination., Results: At an average of 17 months, the mean DASH questionnaire score was unchanged. The pain rating on the visual analog scale was 6 out of 10 before surgery and 4 out of 10 after surgery; this change was not statistically significant. The average range of motion of the PIP joint decreased by 10 degrees at the last evaluation. Grip strength improved from an average of 47 lb to 63 lb after surgery., Conclusions: The subjective and objective functional outcomes in 5 patients more than 1 year after pyrolytic carbon PIP joint arthroplasty for PIP joint trauma were disappointing. For posttraumatic patients, we no longer use pyrolytic carbon PIP joint arthroplasty.
