An anatomic study of the morphologic characteristics of the dorsal capitolunate ligament.

Purpose: There is consensus in favor of a description of the dorsal ligaments of the carpus as not including a direct ligament between the lunate and capitate. On the other hand, there is an anatomical formation which, according to the currently accepted description, corresponds to the dorsal midcarpal capsule, itself thickened by the dorsal intercarpal ligament. The question is whether the capsule at this point deserves to be called an individualizable ligament.

Treatment of 2-part, 3-part, and 4-part proximal humerus fractures from 2016 to 2020: A nationally-representative database.

Introduction: Complex proximal humerus fractures pose challenges in elderly patients, as this common scenario can lead to unpredictable outcomes, regardless of treatment method. Given the evolving nature of the treatment for 3-and-4-part proximal humerus fractures, an epidemiological analysis offers a way to minimize the gap between appropriate understanding and effective intervention. As such, we aimed to i) evaluate the trends of nonoperative and operative management; and ii) compare the complication rates of ORIF to conversion ORIF (to RTSA).

Elevated risk of prosthetic infections in cannabis users after shoulder arthroplasty.

Introduction: An increasing number of states are beginning to legalize recreational cannabis use, and as such, more patients using cannabis are undergoing shoulder arthroplasty procedures. The present study sought to examine the impact of cannabis use on post-operative outcomes. The primary outcomes of interest were postoperative complications, which included infection, periprosthetic fractures, periprosthetic joint infections (PJI), dislocations, and aseptic loosening as well as medical complications.

Postoperative Opioid Dependence in Patients Undergoing Either Total or Reverse Shoulder Arthroplasty for Proximal Humerus Fracture Fixation.

Introduction: In elderly patients who have proximal humerus fractures, treatment commonly involves total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (RSA). Following these procedures, patients often require opioids for postoperative analgesia. This common scenario is of clinical and societal importance, as increased postoperative opioid usage has been shown to worsen outcomes and increase the likelihood for dependence.

Comparative analysis of open versus endoscopic carpal tunnel release in a comprehensive national database.

Purpose: Carpal tunnel syndrome is the most common compressive neuropathy. There is limited evidence to support endoscopic compared to open carpal tunnel release according to the 2016 American Academy of Orthopaedic Surgeons Clinical Practice Guideline on carpal tunnel syndrome. The purpose of the present study was to assess differences between the two procedures by comparing 30- and 90-day complications and mean hospital costs in a large patient population.

Cannabis Use in Patients With Distal Radius Fractures: A Moment of Unity?

Background: As legalization of cannabis spreads, an increasing number of patients who use cannabis are being seen in the clinical setting. This study examined the impact of cannabis and tobacco use on postoperative complications following open reduction and internal fixation (ORIF) of distal radius fractures.

Methods: A national, all-payer database was queried to identify patients who underwent ORIF of a distal radius fracture between 2015 and 2020 (n = 970 747).

Preoperative Corticosteroid Injections Within 4 Weeks of Arthroscopic Shoulder Procedures Are Associated With Increased Postoperative Infection Rates.

Purpose: To refine the understanding of the effect of timing of corticosteroid injections (CSIs) and shoulder arthroscopy on postoperative infection.

Methods: An insurance database was used to determine all patients who underwent shoulder arthroscopy for a 5-year period with an associated preoperative ipsilateral corticosteroid injection. Patients were stratified into cohorts based on timing of preoperative CSI: (1) 0-<2 weeks, (2) 2-<4 weeks, (3) 4-<6 weeks, and (4) 6-<8 weeks.

Selective Thumb Carpometacarpal Joint Denervation Versus Trapeziectomy and Ligament Reconstruction With Tendon Interposition for Painful Arthritis: A Prospective Study With 2 Years of Follow-Up.

Purpose: Thumb carpometacarpal (CMC) joint denervation is a relatively novel method for the management of osteoarthritis-associated pain by selective transection of articular nerve branches of the CMC joint. This study compared functional/patient-reported outcomes after CMC denervation with those after trapeziectomy and ligament reconstruction with tendon interposition (T + LRTI) over a 2-year follow-up period. We hypothesized that the outcomes of denervation and T + LRTI would be similar over the course of the study and at the final 2-year follow-up.

Open versus arthroscopic elbow arthrolysis for primary osteoarthritis: A comparison of demographics and complications at two years.

Introduction: Open techniques have traditionally been utilized in the surgical management of elbow osteoarthritis (OA). However, advances in elbow arthroscopy, in conjunction with the movement towards minimally invasive surgery, have led to an increase in the utilization of an arthroscopic approach. The primary aim of this investigation was to compare demographics and complication rates between patients undergoing open or arthroscopic arthrolysis for elbow OA with a secondary objective of identifying risk factors for infection with each treatment.

The temporal effect of corticosteroid injections into large joints prior to trigger finger release on infection.

Background: Trigger finger may be treated with open surgical release. Local corticosteroid injections have also demonstrated success. Studies suggest recipients of flexor sheath corticosteroid up to 90-days prior to open surgery are at increased risk of post-operative infection.

Rare peripheral nerve tumor of the median nerve.

Peripheral nerve tumors of the median nerve are uncommon. We present a case of a large atypical intraneural perineurioma of the median nerve. In our case, a 27-year-old man with a history of Asperger's and Autism who was diagnosed with a lipofibromatous hamartoma of the median nerve after a biopsy and treated conservatively presented to clinic due to the slowly growing size of his lesion.

Operative Versus Nonoperative Treatment for Closed Displaced Midshaft Clavicle Fractures.

Background: Nonoperative treatment for clavicle fractures has historically been standard of care, but with a concomitant rise in recent operative fixation for displaced midshaft clavicle fractures (MCF), a re-evaluation of treatment modalities is necessary. The purpose of this study was to compare nonunion rates among operative and nonoperative treatment of closed displaced MCF. Specifically, we assessed the following between operative and nonoperative management: (1) 90-day to 1-year nonunion and malunion incidence; (2) 90-day medical complications; and (3) 90-day to 1-year total costs of care.

Partial Resection of First Dorsal Compartment Extensor Retinaculum in De Quervain's Stenosing Tendovaginitis Release.

Various surgical techniques exist to treat de Quervain's stenosing tendovaginitis. Specific surgical techniques for de Quervain's are designed to avoid complications including injury to branches of the superficial branch of the radial nerve, inadequate decompression, reflex sympathetic dystrophy, and palmar subluxation of the released tendons. A simple dorsal incision through the extensor retinaculum is advocated by many as a means to release the compartment while preventing postoperative subluxation.

Rare septic arthritis of the wrist and carpus primary osteoarticular manifestation of : A case report.

is one of the oldest and most studied infections, yet it remains one of the most common causes of infection-related death worldwide. The majority concern pulmonary tuberculosis. Therefore, extrapulmonary cases are rare and are often neglected in the differential diagnosis, especially in chronic musculoskeletal complaints.

Impact of Missing Data on Identifying Risk Factors for Postoperative Complications in Hand Surgery.

Background: The mismanagement of missing data in large clinical databases may lead to inaccurate findings. The purpose of this study was to demonstrate the effects of missing data on hand surgery research findings using an analysis of postoperative morbidity in patients undergoing hospital-based hand surgery.

Methods: The National Surgical Quality Improvement Program database was queried for patients undergoing common hand and upper extremity surgery between 2011 and 2016.

Relative Value Unit Compensation Rates for Hospital-Based Shoulder/Elbow Surgery Versus Hand Surgery.

Upper extremity surgeons perform diverse operations, including hand surgery, microsurgery, and shoulder/elbow arthroscopy and arthroplasty. Declining orthopedic reimbursement rates may encourage surgeons to adjust their case mix, favoring a shift toward procedures with higher compensation. To determine whether upper extremity surgeons and hand-fellowship trainees may be financially incentivized to perform more shoulder/elbow procedures than hand procedures in a hospital-based setting, relative value unit (RVU) compensation rates were compared for these 2 fields.

Equivalent PROMIS Scores after Nonoperative or Operative Treatment of Trapeziometacarpal Osteoarthritis.

Background: Patient-Reported Outcomes Measurement Information System (PROMIS) scores can quantify symptoms and limitations after upper extremity surgery. Our objective was to determine how these scores compare amongst patients with trapeziometacarpal osteoarthritis treated either nonoperatively or operatively.

Methods: In this retrospective comparative study, we compared PROMIS scores (upper extremity function [UEF], pain interference, and depression) between 43 patients who underwent nonoperative treatment (nonsteroidal anti-inflammatory drugs/splinting/injections) and 33 patients who underwent trapeziectomy with ligament reconstruction and tendon interposition for trapeziometacarpal osteoarthritis (minimum 6-month recovery period) by 4 surgeons from 2014-2018.

Peripheral nerve repair throughout the body with processed nerve allografts: Results from a large multicenter study.

Background: Peripheral nerve damage resulting in pain, loss of sensation, or motor function may necessitate a reconstruction with a bridging material. The RANGER® Registry was designed to evaluate outcomes following nerve repair with processed nerve allograft (Avance® Nerve Graft; Axogen; Alachua, FL). Here we report on the results from the largest peripheral nerve registry to-date.

Collagenase Clostridium Histolyticum Injection for Dupuytren Contracture: 2-Year Follow-up.

Background: Dupuytren disease is characterized by the development of palmar fibrous tissue that can lead to fixed flexion contracture (FFC) and contribute to functional loss of the involved digits. Our goal was to investigate rates of contracture resolution and recurrence in patients who underwent enzymatic fasciotomy for Dupuytren contracture consisting of collagenase clostridium histolyticum (CCH) injection followed by passive manipulation combined with splinting and home-based therapy.

Methods: We prospectively enrolled 34 patients (44 metacarpophalangeal [MCP] and 33 proximal interphalangeal [PIP] joints) treated by one orthopaedic hand surgeon between November 2010 and November 2014.

Exposure of the brachial plexus in complex revisions to reverse total shoulder arthroplasty.

Background: Excision of extensive scar tissue (EEST) may be required in certain cases of revision reverse total shoulder arthroplasty (RTSA). Neurovascular structures are at a higher risk of iatrogenic direct injury in these cases. We describe a technique to expose and protect the musculocutaneous and axillary nerves in a series of revision RTSA cases that required EEST.

Autologous Osteoarticular Transfer From the Lateral Femoral Condyle to the Scaphoid Facet in the Treatment of a Malunited Pediatric Distal Radius Fracture With Physeal Bar.

Injury to the articular surface of the distal radius commonly occurs after a fall onto an outstretched hand. Intra-articular fractures that cause joint depression require operative intervention and can be especially challenging in skeletally immature patients. This case report describes the use of an osteoarticular autograft in the treatment of a 13-year-old boy with a malunited distal radius fracture.
