Post-operative complications were compared between subjects who underwent the procedure with regional versus general anesthesia.Results: Ninety-one ulnar nerve in situ decompressions were included in the study, which were performed under regional anesthesia in 55 and general anesthesia in 36 cases. The occurrence of post-operative complications was not significantly different between patients who received regional (n = 7) anesthesia and general (n = 8) anesthesia. None of the complications were directly attributed to the type of anesthesia administered. The change in pre- and post-operative McGowan scores were not significantly different between anesthesia groups (p = 0.81).Conclusion: In situ ulnar nerve decompression at the cubital tunnel under regional anesthesia does not result in increased post-operative complications compared to those surgeries performed under general anesthesia. In situ ulnar nerve decompression performed under regional anesthesia is a safe and reliable option for patients who wish to avoid general anesthesia.Level of Evidence: III.Keywords: cubital tunnel, regional anesthesia, ulnar neuropathy

Small joint arthroplasty of the hand is a well-established surgery that can preserve motion and provide reliable pain relief, joint preservation, and improvement in hand function. Soft-tissue integrity is critical in patient and implant selection to avoid postoperative joint instability. Although instability is more common in nonconstrained implants such as pyrocarbon, silicone arthroplasty is associated with high rates of late implant fracture and failure with resultant recurrent deformity and instability. Additional complications such as stiffness, extension lag, and intraoperative fractures may be mitigated by alterations in surgical technique and postoperative rehabilitation protocols. Revision arthroplasty with soft-tissue stabilization procedures have reliable outcomes and can avoid conversion to arthrodesis. This article will review the surgical indications, outcomes of small joint arthroplasty in the hand, and common complications and their management., (Copyright © 2023 by the American Academy of Orthopaedic Surgeons.)

Background: The loss of extensor mechanism continuity that occurs with patellar and quadriceps tendon rupture has devastating consequences on patient function., Purpose: To describe a treatment strategy for extensor mechanism disruption and evaluate the outcomes of 3 techniques: primary repair, repair with semitendinosus tendon autograft augmentation, and reconstruction with Achilles tendon allograft., Study Design: Case series; Level of evidence, 4., Methods: The authors reviewed surgeries for extensor mechanism disruption performed by a single surgeon between 1999 and 2019. Patient characteristics, imaging studies, surgical techniques, and outcomes were recorded. Primary ruptures with robust tissue quality were repaired primarily, and first-time ruptures with significant tendinosis or moderate tissue loss were repaired using quadrupled semitendinosus tendon autograft augmentation. Patients with failed previous extensor mechanism repair or reconstruction and poor tissue quality underwent reconstruction with Achilles tendon allograft. The primary outcome was extensor mechanism integrity at a minimum 1-year follow-up, with extensor mechanism lag defined as >5° loss of terminal, active knee extension. Secondary outcomes included postoperative knee range of motion, International Knee Documentation Committee (IKDC) and Tegner activity scores, and the radiographic Caton-Deschamps Index., Results: Included were 22 patellar tendon and 21 quadriceps tendon surgeries (patients: 82.5% male; mean age, 48.1 years; body mass index, 31). Seventeen (39.5%) cases underwent primary tendon repair, 13 (30.2%) had repair using semitendinosus tendon autograft augmentation, and 13 (30.2%) underwent reconstruction using an Achilles tendon allograft. Seventeen (39.5%) cases had at least 1 prior failed extensor mechanism surgery performed at an outside facility. At the last follow-up, 4 (9.3%) cases had an extensor mechanism lag, no cases required additional extensor mechanism surgery, and all cases were able to achieve >90° of knee flexion. Postoperative IKDC scores were significantly improved with all methods of extensor mechanism surgery, and postoperative Tegner activity scores were significantly improved in patients who underwent primary repair and Achilles tendon allograft reconstruction ( P < .05 for all)., Conclusion: Primary repair alone, repair using quadrupled semitendinosus tendon autograft augmentation, and reconstruction using Achilles tendon allograft were all effective methods to restore extensor mechanism and knee function with the proper indications. Persistent knee extensor lag was more common in chronic extensor mechanism injuries after failed surgery, although patients still reported significantly improved postoperative functional outcomes., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: M.J.S. and A.J.K. received support from the Quattrone-Foderaro Musculoskeletal-Orthopaedic Surgery Research Innovation Fund and the National Institute of Arthritis and Musculoskeletal and Skin Diseases for the Musculoskeletal Research Training Program (T32AR56950).

Although anterior shoulder instability is most commonly treated with arthroscopic fixation, open labral repair with capsular shift may be best for select patients and in cases of revision stabilization without significant bone loss. The technique described in this article uses the deltopectoral interval; it involves careful dissection of the subscapularis from the anterior capsule, repair of the Bankart lesion, and a lateral and superior capsular shift using all-suture anchors in the humeral head. Advantages of this technique include meticulous control of anchor placement and the ability to provide additional stability via a lateral and superiorly directed capsular shift. This operation can be performed in a reliable, efficient, and reproducible manner.
