Abstract To present our clinical experience with a volar scapholunate (SL) ligament reconstruction using a strip of the long radiolunate ligament. This was a single-institution observational study (2004–2022) of SL ligament injuries with evidence of a torn volar component on arthroscopy that received volar capsulodesis with/without a dorsal repair. The postoperative range of motion (ROM), grip strength, complications, and secondary surgery (e.g., four-corner fusion or total wrist fusion), and radiographic changes were reported. Disabilities of arm, shoulder, and hand/patient-rated wrist evaluation (DASH/PRWE) scores were prospectively collected. Patients were stratified by static versus dynamic/predynamic SL diastasis and by isolated volar versus volar and dorsal ligament injury. Twenty-eight patients (15 females and 13 males) with a mean age of 35.1 years (± 15.7) met the inclusion criteria. The follow-up was 86.3 months (± 53.4; minimum 11 months). Most (26/28) patients were right-handed. The majority (20/28) of the patients presented ≥ 6 weeks postinjury. Few (4/28) used tobacco. Most (20/28) patients had dynamic/predynamic injuries. Postoperatively, the mean pronation/supination was 83 degrees/83 degrees, flexion/extension was 56 degrees/61 degrees, ulnar deviation was 30 degrees, and radial deviation (RD) was 19 degrees (n = 13). The mean grip strength was 78.8% (± 30.4) of the contralateral normal side (n = 14). Except for increased RD in patients with dynamic/predynamic injuries (p = 0.02), there were no other ROM differences. SL widening (>3 mm) postoperatively was observed in 33.3% (2/6) of static versus none of the dynamic/predynamic injuries (p = 0.165). There were only two postoperative complications, both surgical site infections. Two patients had persistent pain and required secondary surgery at a median of 48 months. At 86.9 months, patients reported a mean DASH of 16.4 (± 17.8) and a PRWE of 24.6 (± 23.6), and 78.9% (15/19) returned to prior work. We report long-term functional outcomes after a volar capsulodesis for volar SL injuries. This appears to be a safe procedure with an acceptable complication rate and low disability after 7 years. Most (approximately 79%) patients returned to their previous employment. A larger comparative study will be required to prove superiority to other types of repairs. Level IV, Case series.

Background: A cohort of patients with traumatic brachial plexus injuries (BPIs) underwent elective amputation following unsuccessful surgical reconstruction or delayed presentation. The results of amputation with and without a myoelectric prosthesis (MEP) using nonintuitive controls were compared. We sought to determine the benefits of amputation, and whether fitting with an MEP was feasible and functional. Methods: We conducted a retrospective review of patients with BPI who underwent elective upper-extremity amputation at a single institution. Medical records were reviewed for demographics, injury and reconstruction details, amputation characteristics, outcomes, and complications. Prosthesis use and MEP function were assessed. The minimum follow-up for clinical outcomes was 12 months. Results: Thirty-two patients with BPI and an average follow-up of 53 months underwent elective amputation between June 2000 and June 2020. Among the cases were 18 transhumeral amputations, 12 transradial amputations, and 2 wrist disarticulations. There were 29 pan-plexus injuries, 1 partial C5-sparing pan-plexus injury, 1 lower-trunk with lateral cord injury, and 1 lower-trunk injury. Amputation occurred, on average, at 48.9 months following BPI and 36.5 months following final reconstruction. Ten patients were fitted for an MEP with electromyographic signal control from muscles not normally associated with the intended function (nonintuitive control). Average visual analog scale pain scores decreased post-amputation: from 4.8 pre-amputation to 3.3 for the MEP group and from 5.4 to 4.4 for the non-MEP group. Average scores on the Disabilities of the Arm, Shoulder and Hand questionnaire decreased post-amputation, but not significantly: from 35 to 30 for the MEP group and from 43 to 40 for the non-MEP group. Patients were more likely to be employed following amputation than they were before amputation. No patient expressed regret about undergoing amputation. All patients in the MEP group reported regular use of their prosthesis compared with 29% of patients with a traditional prosthesis. All patients in the MEP group demonstrated functional terminal grasp/release that they considered useful. Conclusions: Amputation is an effective treatment for select patients with BPI for whom surgical reconstruction is unsuccessful. Patients who underwent amputation reported decreased mechanical pain, increased employment rates, and a high rate of satisfaction following surgery. In amputees with sufficient nonintuitive electromyographic signals, MEPs allow for terminal grasp/release and are associated with high rates of prosthesis use.

» Management of tetraplegia should be individualized to a patient’s particular deficiencies and functional goals. » Surgical decision-making for upper-extremity reconstruction in patients with tetraplegia relies on a thorough physical examination to determine which nerves and muscles remain under volitional control with adequate strength for transfer. » Peripheral nerve transfers, either in conjunction with or in place of traditional tendon transfers, enable providers to offer an expanded set of surgical options for patients with tetraplegia who are seeking upper-extremity reconstruction. » All upper-extremity reconstructive efforts should be carefully considered with regard to their potential effects on the availability of future reconstructive efforts.
