De Quervain's Tenosynovitis Release With Excision of the First Dorsal Compartment: Novel Surgical Technique and a Case Series.

Incision of the dorsal side of the tendon sheath in release of De Quervain's tenosynovitis has traditionally been advocated to prevent the risk of volar tendon subluxation. We describe a novel technique of complete excision, rather than simple incision, of the first dorsal compartment tendon sheath. Over a 10-year period, 147 patients (154 wrists) underwent first dorsal compartment release using this technique of complete excision of the sheath.

Nonoperative treatment of distal humerus fractures in the elderly yields satisfactory functional outcomes and low conversion to delayed surgery: a systematic review.

Background: Distal humerus fractures (DHFs) pose a treatment challenge in elderly patients. We sought to systematically review and report the clinical outcomes of the nonoperative approach (eg, "bag of bones") for the treatment of these injuries and the rate of conversion to delayed surgery.

Methods: A comprehensive review of the literature using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines was conducted.

The Thrower's Fracture A Case Report and Literature Review.

There is a paucity of literature regarding atraumatic distalthird humeral shaft fractures, or "thrower's fracture." We report on a case of a healthy adult male, amateur athlete, who suffered an atraumatic fracture of the humerus while throwing a softball with his dominant arm. He underwent operative repair and developed a radial nerve palsy postoperatively that recovered 4/5 strength by 6 weeks and 5/5 strength by 12 weeks.

Ulnar-Sided Digital Nerve Tumor of the Thumb in the Professional Baseball Player Who Uses Grip-Adjusting Batting Equipment: A Report of 2 Cases.

Neuropathy of the ulnar digital nerve of the thumb is a relatively rare clinical entity. We report 2 cases of ulnar-sided digital nerve tumors of the thumb in 2 professional baseball players who routinely used grip-adjusting batting equipment. Symptomatic relief was achieved with nonsurgical treatment that allowed both players to continue playing during critical times during their season.

Deep Penetrating Kerosene Exposure in the Hand Mimicking Deep Space Infection.

In this case report, we review the clinical course of an adolescent who sustained a low-velocity, low-pressure, penetrating wound to the midpalmar aspect of the hand with a kerosene containing thermometer. The exposure led to a clinical picture of an acute midpalmar abscess within 24 hours. Despite irrigation and debridement of frank purulent material, cultures and pathology remained negative for infection.

Return to play and performance after surgical repair of distal biceps tendon ruptures in National Football League athletes.

Background: The purpose of this study was to determine whether surgical repair of distal biceps tendon ruptures in professional football players would lead to a decrease in postinjury performance when compared to preinjury performance and control-matched peers. We also sought to define return to sport, postinjury career length, and games played per season in National Football League players following surgical repair of distal biceps tendon ruptures.

Methods: Data for National Football League players who underwent surgical repair of distal biceps tendon ruptures during a 20-year time period were collected.

The Essex-Lopresti Injury.

The Essex-Lopresti injury is caused by a high energy mechanism and consists of a characteristic triad: a comminuted radial head fracture, disruption of the distal radioulnar joint, and tearing of the interosseous membrane. These injuries are often difficult to diagnosis on initial evaluation, and the majority are missed acutely. Chronic Essex-Lopresti injuries lead to radioulnar longitudinal instability, proximal radius migration, ulnocarpal impaction, and chronic elbow pain.

The naked capitellum: a surgeon's guide to intraoperative identification of posterolateral rotatory instability.

Hypothesis: This study's purpose was to provide a reproducible way for surgeons to intraoperatively assess the elbow's lateral ulnar collateral ligament origin and determine whether there is posterolateral rotatory instability (PLRI) despite an intact common extensor origin (CEO). We hypothesized that we could re-create clinically relevant disruption of lateral supporting structures despite an intact CEO and illustrate progressive elbow PLRI.

Methods: The relationship of the lateral capsule to the capitellum articular surface was noted in 8 cadaveric upper extremities.

Performance outcomes after medial ulnar collateral ligament reconstruction in Major League Baseball positional players.

Background: We sought to determine whether professional baseball positional players who underwent medial ulnar collateral ligament (MUCL) reconstruction demonstrate decreases in performance on return to competition compared with preoperative performance metrics and their control-matched peers.

Methods: Data for 35 Major League Baseball positional players who underwent MUCL reconstruction during 31 seasons were obtained. Twenty-six players met inclusion criteria.

Scaphoid Healing Required for Unrestricted Activity: A Biomechanical Cadaver Model.

Purpose: To determine if scaphoid fractures with bridging bone of 50% of their width treated with a centrally placed screw will restore biomechanical integrity equivalent to that of the intact scaphoid.

Methods: Twenty-four fresh cadaver scaphoids were used. Six were left intact to serve as the control group.

Microsurgery Case Volume During Orthopedic Surgery Residency: A 7-Year Assessment.

Background: Microsurgery is a specialized surgical technique with wide clinical application. The purpose of this study was to analyze case logs of graduating orthopedic surgery residents to assess trends in case volume for microsurgery procedures.

Methods: Accreditation Council for Graduate Medical Education case log reports were analyzed for microsurgery experience from 2007 to 2013.

Accelerated Degenerative Joint Disease After Staged Hip Arthroscopy and Periacetabular Osteotomy in a Patient with Hip Dysplasia.

Hip dysplasia, when significant, is effectively treated with periacetabular osteotomy. There have been good results reported with hip arthroscopy when dysplasia is mild. However, when dysplasia is significant, hip arthroscopy with labral repair alone has led to poor results and even rapid decline to end stage arthritis.

Performance Outcomes After Hook of Hamate Fractures in Major League Baseball Players.

Background: Basketball players are at risk for foot injuries, including Jones fractures. It is unknown how this injury affects the future play and performance of athletes.

Hypothesis: National Basketball Association (NBA) players who sustain Jones fractures of the base of the fifth metatarsal have high rates of return to play and do not experience a decrease in performance on return to competition when compared with preinjury and with control-matched peers.

Evaluation of Automated Volumetric Cartilage Quantification for Hip Preservation Surgery.

Automating the process of femoroacetabular cartilage identification from magnetic resonance imaging (MRI) images has important implications to guiding clinical care by providing a temporal metric that allows for optimizing the timing for joint preservation surgery. In this paper, we evaluate a new automated cartilage segmentation method using a time trial, segmented volume comparison, overlap metrics, and Euclidean distance mapping. We report interrater overlap metrics using the true fast imaging with steady-state precession MRI sequence of 0.
