RESUMO
PURPOSE: Nerve transfers to restore or augment function after spinal cord injury is an expanding field. There is a paucity of information, however, on the use of nerve transfers for patients having undergone spine surgery. The incidence of neurologic deficit after spine surgery is rare but extremely debilitating. The purpose of this study was to describe the functional benefit after upper extremity nerve transfers in the setting of nerve injury after cervical spine surgery. METHODS: A single-center retrospective review of all patients who underwent nerve transfers after cervical spine surgery was completed. Patient demographics, injury features, spine surgery procedure, nerve conduction and electromyography study results, time to referral to nerve surgeon, time to surgery, surgical technique and number of nerve transfers performed, complications, postoperative muscle testing, and subjective outcomes were reviewed. RESULTS: Fourteen nerve transfers were performed in 6 patients after cervical spine surgery. Nerve transfer procedures consisted of a transfer between a median nerve branch of flexor digitorum superficialis into a biceps nerve branch, an ulnar nerve branch of flexor carpi ulnaris into a brachialis nerve branch, a radial nerve branch of triceps muscle into the axillary nerve, and the anterior interosseous nerve into the ulnar motor nerve. Average patient age was 55 years; all patients were male and underwent surgery on their left upper extremity. Average referral time was 7 months, average time to nerve transfer was 9 months, and average follow-up was 21 months. Average preoperative muscle grading was 0.9 of 5, and average postoperative muscle grading was 4.1 of 5 ( P < 0.00001). CONCLUSIONS: Upper extremity peripheral nerve transfers can significantly help patients regain muscle function from deficits secondary to cervical spine procedures. The morbidity of the nerve transfers is minimal with measurable improvements in muscle function.

ABSTRACT: Synovial lipomatosis is a rare condition characterized by adipocyte proliferation within joint synovial tissue. It most commonly affects the knee and is typically intra-articular. Only 5 published case reports describe extra-articular synovial lipomatosis of the wrist. We present a case of a sexagenarian patient seen for his wrist arthropathy. His x-ray revealed pan-wrist arthritis and inflammatory soft tissue swelling. The patient was slated for a wrist fusion and Darrach procedure. Following the dorsal skin incision in the operating room, an unusual adipose mass was identified infiltrating all extensor compartments: midcarpal, radiocarpal, and distal radioulnar joints. The mass was excised and sent to pathology prior to proceeding with the slated surgery. Synovial lipomatosis was diagnosed postoperatively based on histopathology. Six weeks postoperatively, the wrist fusion had healed clinically and radiographically, and his pain had improved. There was no evidence of recurrence. Synovial lipomatosis is a rare entity that may imitate multiple other pathologies. It is possible that synovial lipomatosis may represent a secondary occurrence following degenerative articular disease or trauma in older patients. This is the first case report to date describing synovial lipomatosis of the wrist with extra-articular extension in the setting of pan-carpal wrist arthritis.

PURPOSE: Proximal interphalangeal joint (PIPJ) fracture dislocations are complex injuries that can result in persistent pain, stiffness, and angulation. Hemihamate arthroplasty (HHA) can be used to reconstruct the base of the middle phalanx in cases of unstable PIPJ fracture dislocations. Despite previous case series describing good outcomes with HHA, it has not gained widespread use. The purpose of this study is to describe our straightforward, reproducible technique and to demonstrate the benefit in motion after the procedure in chronic unstable PIPJ fracture dislocations. METHODS: All patients with chronic, unstable PIPJ fracture dislocations requiring joint resurfacing of greater than 40% of the base of the middle phalanx treated with HHA were retrospectively reviewed. Patient demographics, injury features, surgical technique, preoperative and postoperative PIPJ range of motion and arc of motion, time to surgery, and complications were reviewed. Any fracture amenable to fixation or cases with radiographic evidence of arthritis or injury to the head of the proximal phalanx were excluded. RESULTS: Eleven cases were reviewed. The mean patient age was 35 years. The mean time from injury to surgery was 6 months. The mean joint surface involved was 64%. The mean PIPJ arc of motion was 17 degrees preoperatively and 63 degrees postoperatively. The mean bone block size required was 8 × 8 × 8 mm. The mean follow-up was 26 months. Postoperative pain at the PIPJ on the visual analog scale was 0.4 (scale of 0 to 10). Complications included 2 patients requiring tenolysis. CONCLUSIONS: Despite the lack of a perfect geometric recreation of the base of the middle phalanx with the hamate, patients recover acceptable PIPJ motion and have minimal pain. Hemihamate arthroplasty is a good option for any patient with minimal motion of their PIPJ and a chronic, unstable fracture dislocation.

INTRODUCTION: The incidence of malignant peripheral nerve sheath tumors (MPNSTs) is 0.001%. Commonly, MPNST arise in neurofibromatosis; however, they can occur sporadically, de novo or from a preexisting neurofibroma. Malignant peripheral nerve sheath tumors are aggressive tumors with high rates of local recurrence and metastasis. The prognosis is poor with 5-year survival rates of 15% to 50%. Unfortunately, given the rarity of these tumors, it is not clear how to best manage these patients. The purposes of this study were (1) to discuss our experience with MPNST and particularly our difficulties with diagnosis and management, and (2) to review the literature. MATERIALS AND METHODS: We report on all tumors of the brachial plexus excised between 2013 and 2019. We report 3 cases of MPNST, their treatment, and their outcomes. RESULTS: Thirteen patients underwent surgical excision of an intrinsic brachial plexus mass. Three of these patients (2 male, 1 female; average age, 36 years) were diagnosed with an MPNST. Two patients with an MPNST had neurofibromatosis type 1. All patients with an MPNST had a tumor >8 cm, motor and sensory deficits, and pain. All 3 patients with MPNST underwent a magnetic resonance imaging (MRI) before diagnosis. The average time from initial symptom onset to MRI was 12.3 months. Only 1 of the MRIs suggested a malignant tumor, with no MRI identifying an MPNST. One patient underwent an excisional biopsy, and 2 had incisional biopsies. Because of the lack of diagnosis preoperatively, all patients had positive margins given the limited extent of surgery. Returning for excision in an attempt to achieve negative margins in a large oncologically contaminated field was not possible because defining the boundaries of the initial surgical field was unachievable; therefore, the initial surgery was their definitive surgical management. All patients were referred to oncology and received radiation therapy. CONCLUSIONS: Malignant peripheral nerve sheath tumors must be suspected in enlarging masses (>5 cm) with the constellation of pain, motor, and sensory deficits. Computed tomography- or ultrasound-guided core needle biopsy under brachial plexus block or sedation is required for definitive diagnosis to allow for a comprehensive approach to the patient's tumor with a higher likelihood of disease-free survival.

ABSTRACT: Parsonage Turner syndrome (PTS) is the development of severe, spontaneous pain with subsequent nerve palsy. Unfortunately, many patients never achieve full functional recovery, and many have chronic pain. The use of nerve transfers in PTS has not been reported in the literature. We present 4 cases of PTS treated surgically with primary nerve transfer and neurolysis of the affected nerve following the absence of clinical and electrodiagnostic recovery at 5 months from onset. In addition, we present a cadaver dissection demonstrating an interfascicular dissection of the anterior interosseous nerve (AIN) into its components to enable a fascicular transfer in partial AIN neuropathy. Two patients with complete axillary neuropathy underwent a neurorrhaphy between the nerve branch to the lateral head of the triceps and the anterior/middle deltoid nerve branch of the axillary nerve. Two patients with partial AIN neuropathy involving the FDP to the index finger (FDP2) underwent a neurorrhaphy between an extensor carpi radialis brevis nerve branch and the FDP2 nerve branch. All patients had neurolysis of the affected nerves. All subjects recovered at least M4 motor strength. The cadaver dissection demonstrates 3 separate nerve fascicles of the AIN into FPL, FDP2, and pronator quadratus that can be individually selected for reinnervation with a fascicular nerve transfer. Functional recovery for patients with PTS with neurolysis alone is variable. Surgical treatment with neurolysis and a nerve transfer to improve functional recovery when no recovery is seen by 5 months is an option.

BACKGROUND: A femoral nerve injury may result in cutaneous sensory disturbances of the anteromedial thigh and complete paralysis of the quadriceps femoris muscles resulting in an inability to extend the knee. The traditional mainstay of treatment for femoral neuropathy is early physiotherapy, knee support devices, and pain control. Case reports have used the anterior division of the obturator nerve as a donor nerve to innervate the quadriceps femoris muscles; however, a second nerve transfer or nerve grafting is often required for improved outcomes. We suggest a novel technique of combining an innervated, pedicled gracilis transfer with an adductor longus to rectus femoris nerve transfer to restore the strength and stability of the quadriceps muscles. METHODS: This is a case series describing the use of a pedicled gracilis muscle transposed into the rectus femoris position with a concomitant nerve transfer from the adductor longus nerve branch into the rectus femoris nerve branch to restore quadriceps function after iatrogenic injury (hip arthroplasty) and trauma (gunshot wound). RESULTS: With electrodiagnostic confirmation of severe denervation of the quadriceps muscles and no evidence of elicitable motor units, 2 patients (average age, 47 years) underwent a quadriceps muscle reconstruction with a pedicled, innervated gracilis muscle and an adductor longus to recuts femoris nerve transfer. At 1 year follow-up, the patients achieved 4.5/5 British Medical Research Council full knee extension, a stable knee, and the ability to ambulate without an assistive aid. CONCLUSIONS: The required amount of quadriceps strength necessary to maintain quality of life has not been accurately established. In the case of femoral neuropathy, we assumed that a nerve transfer alone and a gracilis muscle transfer alone would not provide enough stability and strength to restore quadriceps function. We believe that the restoration of the quadriceps function after femoral nerve injury can be achieved by combining an innervated, pedicled gracilis transfer with an adductor longus to rectus femoris nerve transfer with low morbidity and no donor defects.

ABSTRACT: Peroneal intraneural ganglia are rare, and their management is controversial. Presently, the accepted treatment of intraneural ganglia is decompression and ligation of the articular nerve branch. Although this treatment prevents recurrence of the ganglia, the resultant motor deficit of foot drop in the case of intraneural peroneal ganglia is unsatisfying. Foot drop is classically treated with splinting or tendon transfers to the foot. We have recently published a case report of a peroneal intraneural ganglion treated by transferring a motor nerve branch of flexor hallucis longus into a nerve branch of tibialis anterior muscle in addition to articular nerve branch ligation and decompression of the intraneural ganglion to restore the patient's ability to dorsiflex. We have since performed this procedure on 4 additional patients with appropriate follow-up. Depending on the initial onset of foot drop and time to surgery, nerve transfer from flexor hallucis longus to anterior tibialis nerve branch may be considered as an adjunct to decompression and articular nerve branch ligation for the treatment of symptomatic peroneal intraneural ganglion.

PURPOSE: Treatment patterns of carpal tunnel surgery by members of the American Society of Surgery of the Hand (ASSH) have recently been published. The majority of cases in this study were performed in the general operating room with intravenous (IV) sedation or a Bier block. Patients were most commonly prescribed hydrocodone for postoperative pain. The majority of carpal tunnel releases at our center are performed under local anesthesia alone, with plain acetaminophen (Tylenol) or codeine prescribed for postoperative pain. The authors were interested in determining whether these differences were specific to our center or whether there were nationwide differences among the Canadian Society of Plastic Surgery (CSPS) members compared to the ASSH members. We aimed to conduct a similar study to assess current trends across members of the CSPS to assess similarities and differences compared with current practices by members of the ASSH. METHODS: A 10-question survey, modeled after a previously published study, was sent electronically to Canadian plastic surgeons (n = 400). A description and a link to the survey was sent via e-mail and data were anonymously submitted and analyzed using descriptive statistics. RESULTS: The online survey was completed by 183 surgeons (46%). The local procedure room is used by 161 (surgeons 88%), whereas 15 surgeons (8%) used the general operating room. Subcutaneous local anesthetic is used by 98 surgeons (54%), a median nerve block by 68 (7%), a full wrist block used by 6 (3%), local anesthesia with IV sedation used by 6 (3%), a Bier block used by 3 (2%), and a general anesthetic used by 1 (0.5%). After surgery, 70 surgeons (38%) prescribed codeine, 49 (27%) prescribed plain paracetamol, 24 (13%) prescribed nonsteroidal anti-inflammatories, 21 (12%) prescribed tramadol, and 21 (12%) prescribed a narcotic stronger than codeine. CONCLUSIONS: Compared with data obtained from ASSH members, differences in practice by Canadian plastic surgeons responding to this survey appear to be related to type of anesthetic used and postoperative analgesia provided. The majority of procedures in this study were performed in a local procedure room under local anesthetic alone and the majority of patients are discharged with codeine or paracetamol. CLINICAL RELEVANCE: This study draws comparisons between Canadian plastic surgeons and members of the ASSH with respect to carpal tunnel surgery and adherence to the American Academy of Orthopaedic Surgeons Clinical Practice Guideline on the Diagnosis and Treatment of Carpal Tunnel Syndrome.

INTRODUCTION: "Morton neuroma" is a common cause of forefoot pain with numbness frequently occurring in the distribution of the third common digital nerve. After the failure of nonoperative measures, decompression with excision of the neuroma is common practice. Residual numbness and recurrent pain has been reported as a consequence of this treatment option. This study describes excision of the neuroma with interpositional nerve grafting as a treatment option for Morton neuroma. This proposed technique has the benefit of reducing pain, reducing recurrent secondary neuromas and restoring postexcision sensory deficits. METHODS: A retrospective chart review of patients who underwent elective primary excision of a Morton neuroma with interpositional nerve grafting was undertaken. Patient demographics, surgical technique, and clinical outcomes, such as pain, neuroma recurrence, 2-point discrimination, numbness, and weight-bearing status at minimum of 1 year postoperation, are reported. RESULTS: Eight patients (9 neuromas) underwent excision of the Morton neuroma with interpositional nerve grafting after failing nonoperative measures. At final follow-up, all patients had improvement of pain and there were no neuroma recurrences. Sensation to the grafted hemi-toe returned in all but 1 case. All patients returned to full weight-bearing status. Although no major complications were reported, wound dehiscence secondary to a hematoma occurred in 1 case. CONCLUSIONS: Excision and interpositional nerve grafting is an effective treatment for Morton neuroma as it alleviates pain, numbness and restores sensation with minimal morbidity and complications.

BACKGROUND: Modern oncologic surgery aims not only to obtain tumor-free margins but also to spare or reconstruct limb function and preserve quality of life. A negative tumor margin in the digit generally requires amputation; therefore, function is preserved with reconstruction. We report results of simultaneous ablative tumor resection and reconstruction with a great toe transfer in patients requiring surgery for aggressive benign and malignant thumb tumors. METHODS: Between 2000 and 2009, three patients with extensive soft tissue tumors of the distal thumb underwent amputation to obtain wide negative surgical margins. In each case, an immediate trimmed toe-to-thumb transfer was performed. Results, evaluated retrospectively, included a review of perioperative complications, donor-site morbidity, oncologic status, objective functional outcomes, and subjective patient satisfaction. RESULTS: Three patients were found with either locally aggressive benign (n = 1) or malignant (n = 2) tumors of the thumb. All patients underwent immediate reconstruction after amputation through the base of the proximal phalanx for tumor eradication. No perioperative complications were encountered, and all toes survived. Full thumb opposition and protective sensation were achieved in all patients. All patients returned to their previous occupation without functional limitations. There is no local or distant tumor recurrence. Delayed wound healing at the ipsilateral foot donor site occurred in all 3 patients. Wet-to-dry dressing changes were successful in 2 patients, whereas the third patient required full-thickness skin grafting. All patients were satisfied with their reconstruction. CONCLUSIONS: An immediate great toe-to-thumb transfer should be considered when thumb amputation is required to satisfy adequate oncologic margins. Such a transfer provides simultaneous restoration of digit length, position, sensation, and acceptable esthetics. This procedure is technically demanding and requires an experienced microsurgical team as well as appropriate patient counseling and consent before surgery.

PURPOSE: To evaluate a surgical technique of treating nondisplaced waist and proximal pole scaphoid nonunions without avascular necrosis (AVN). METHODS: We performed a retrospective review of all patients with nondisplaced, scaphoid waist or proximal pole nonunions without AVN treated with the following technique. Two K-wires are positioned along the scaphoid axis to stabilize the proximal and distal poles. Debridement with a curette or burr is performed parallel to the nonunion site until the K-wires are visualized and punctate bleeding of the proximal and distal fragments is encountered. The volar, radial fibrous union is left intact. Distal radius cancellous bone graft is packed into the nonunion site. A headless screw is placed perpendicular to the fracture and the K-wires are removed. RESULTS: Between 2012 and 2014, 12 patients (ages 13-29 y) with clinical and radiographic evidence (10 had computed tomography or magnetic resonance imaging; 2 had radiographs only) of scaphoid nonunion were identified (10 transverse waist and 2 proximal pole fractures). Median interval from injury to surgery was 38 weeks (range, 3 mo to 9 y). Four patients were active smokers and 2 had failed previous iliac crest bone grafting. All patients healed as confirmed by computed tomography. Average time to union was 14 weeks (range, 6-31 wk). Four patients had delayed union requiring a bone stimulator. All patients had resolution of pain and there were no complications. CONCLUSIONS: The technique described is an effective and efficient method of treating nondisplaced scaphoid nonunions without AVN. We suggest that complete debridement of the nonunion is not essential to achieve union. In addition, pinning the proximal and distal scaphoid poles initially and maintaining the volar fibrous union of the scaphoid nonunion stabilizes the fracture fragments, increasing the technical ease of grafting and fixation. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

BACKGROUND: Four-corner fusion (4CF) is a common treatment for midcarpal arthritis; however, alternatives including 2-corner fusion (2CF) and 3-corner fusion (3CF) have been described. Limited literature suggests 2CF and 3CF may improve range of motion but have higher complication rates. Our objective is to compare function and patient-reported outcomes following 4CF, 3CF, and 2CF at our institution. METHODS: Adult patients undergoing 4CF, 3CF, and 2CF from 2011 to 2021 who attended at least one follow-up were included. Four-corner fusion patients were compared with those who underwent either 3CF or 2CF using staple fixation. Outcomes include nonunion rate, reoperation rate, progression to wrist fusion, range of motion, and patient-reported pain, satisfaction, and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. RESULTS: A total of 58 patients met inclusion criteria. There were 49 4CF and 9 2CF or 3CF patients. Nonunion rates, progression to wrist fusion, and repeat surgery for any indication were not significantly different among groups. Range of motion (flexion-extension, radial-ulnar deviation) and grip strength at postoperative visits were not significantly different. Significantly more 4CF patients required bone grafting. Pain, overall satisfaction, and DASH scores were similar. CONCLUSIONS: Although prior studies suggest increased risk of nonunion and hardware migration after 2CF/3CF, we did not observe higher complication rates compared with 4CF. Range of motion, strength, and patient-reported outcomes were similar. While 4CF is traditionally the procedure of choice for midcarpal fusion, we found that when using a staple fixation technique, 2CF and 3CF have comparable clinical and patient-reported outcomes yet decrease the need for autologous bone grafting.
RESUMO
BACKGROUND: Injuries to the deep peroneal nerve result in tibialis anterior muscle paralysis and associated loss of ankle dorsiflexion. Nerve grafting of peroneal nerve injuries has led to poor function; therefore, tendon transfers and ankle-foot orthotics have been the standard treatment for foot drop. QUESTIONS/PURPOSES: We (1) describe an alternative surgical technique to obtain ankle dorsiflexion by partial tibial nerve transfer to the motor branch of the tibialis anterior muscle; (2) evaluate ankle dorsiflexion strength using British Medical Research Council grading after nerve transfer; and (3) qualitatively determine factors that influence functional success of surgery. METHODS: We retrospectively reviewed 11 patients treated with partial tibial nerve transfers after peroneal nerve injury. Pre- and postoperative motor strength was measured. Patients completed questionnaires regarding pre- and postoperative gait and disability. RESULTS: One patient regained Grade 4 ankle dorsiflexion, three patients regained Grade 3, one patient regained Grade 2, and two patients regained Grade 1 ankle dorsiflexion. Four patients did not regain any muscle activity. Clinically apparent motor recovery occurred an average 7.6 months postoperatively. A majority of patients (nine) could walk and participate in activities. Seven patients did not wear ankle-foot orthotics and four patients did not limp. The donor deficits included weak toe flexion (two patients) and reduced calf circumference (seven patients). CONCLUSION: Our observations suggest nerve transfers to the deep peroneal nerve provide inconsistent ankle dorsiflexion strength, possibly related to the mechanism of peroneal nerve injury or delays in surgery. Despite variable strength, four patients achieved M3 or greater motor recovery, which enabled them to walk without assistive devices. LEVEL OF EVIDENCE: Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Injuries to the common peroneal nerve can be functionally debilitating with few treatment options. Traditionally, tendon transfers and ankle-foot orthotics have been the standard treatment of foot drop with satisfactory patient outcomes. The purpose of this manuscript is to describe an alternative surgical technique option to obtain ankle dorsiflexion in patients with foot drop using a partial nerve transfer from the tibial nerve to the motor branch of the tibialis anterior.

PURPOSE: Wrist arthrodesis, first carpometacarpal joint arthrodesis, and thumb interphalangeal joint arthrodesis can be used in conjunction with other reconstructive measures to improve function and grasp in patients with complete brachial plexus injuries. This study evaluates wrist arthrodesis, first carpometacarpal joint arthrodesis, and thumb interphalangeal joint arthrodesis as measured by fusion rate, complications, and clinical outcomes. METHODS: A retrospective chart review was performed for 24 skeletally mature patients with brachial plexus injuries treated with wrist arthrodesis by a dorsal plating technique, first carpometacarpal joint arthrodesis by staples, and thumb interphalangeal joint arthrodesis by a tension band wiring technique. Nineteen patients were subjectively evaluated using prearthrodesis and postarthrodesis Disabilities of the Shoulder, Arm, and Hand scores, visual analog pain scores, and a visual analog scale assessing appearance, function, hygiene, ease of daily care, pain, and overall satisfaction. RESULTS: There was 100% union rate with 1 postarthrodesis complication. One patient required wrist fusion plate removal because of painful hardware. Subjective patient assessments showed a statistically significant (P < .001) improvement in Disabilities of the Shoulder, Arm, and Hand scores (from 51 to 28) and pain scores (from 5.3 to 3.2) before and after arthrodeses. The visual analog questionnaire results revealed improvements in appearance, function, daily cares, hygiene, pain, and satisfaction. CONCLUSIONS: Wrist arthrodesis, first carpometacarpal joint arthrodesis, and thumb interphalangeal joint arthrodesis had high union rates with minimal complications. Patients benefited from the improved function of their upper extremities and were satisfied with the surgery. The use of wrist, first carpometacarpal joint, and thumb interphalangeal joint arthrodeses in combination should be considered one of the reconstructive possibilities for patients with complete or nearly complete brachial plexus injuries.

The use of the free functioning, innervated gracilis muscle has evolved to become an invaluable tool in the restoration of elbow flexion and prehension in patients undergoing reconstruction following brachial plexus injuries. Although there are many different methods of the gracilis muscle harvest, most if not all harvest methods begin proximally. The purpose of this article is to describe a novel distal harvest technique of the gracilis myocutaneous flap for brachial plexus patients requiring restoration of elbow or finger flexion. A harvest method commencing with a distal dissection either at the distal insertion of the gracilis at the pes anserine or at the distal medial thigh at the myotendinous junction will be described. The advantage of this novel method is to ensure that the entire gracilis muscle and its tendon are harvested to maximize the length of tendon that can be secured by a Pulvertaft weave into the biceps tendon or the finger flexors for elbow flexion and finger flexion respectively.

Background: Transfer of the anterior interosseous nerve (AIN) into the ulnar motor branch improves intrinsic hand function in patients with high ulnar nerve injuries. We report our outcomes of this nerve transfer and hypothesize that any improvement in intrinsic hand function is beneficial to patients. Methods: A retrospective review of all AIN-to-ulnar motor nerve transfers, including both supercharged end-to-side (SETS) and end-to-end (ETE) transfers, from 2011 to 2018 performed by 2 surgeons was conducted. All adult patients who underwent this nerve transfer for any reason with greater than 6 months' follow-up and completed charts were included. Primary outcome measures were motor function using the British Medical Research Council (BMRC) grading system and subjective satisfaction with surgery using a visual analog scale. Secondary outcome measures included complications and donor site deficits. Results: Of the 57 patients who underwent nerve transfer, 32 patients met the inclusion criteria. The average follow-up and average time to surgery were 12 and 15.6 months, respectively. The overall average BMRC score was 2.9/5, with a trend toward better recovery in patients who received earlier surgery (<12 months = BMRC 3.7, ≥12 months = BMRC 2.2; P < .01). Patients with an SETS transfer had better results that those with an ETE transfer (SETS = 3.2, ETE = 2.6). There were no donor deficits after operation. One patient developed complex regional pain syndrome. Conclusions: Patients with earlier surgery and an in-continuity nerve (receiving an SETS transfer) showed improved recovery with a higher BMRC grade compared with those who underwent later surgery. Any improvements in intrinsic hand function would be beneficial to patients.

We report a case of bilateral ulnar neuropathy after bilateral open carpal tunnel release. Displacement of the flexor tendons anterior to the hook of hamate caused impingement on the ulnar nerve. Symptoms resolved after hook of hamate resection.
