METHODS: Seventy thumb CMC arthroscopic hemitrapeziectomies with a mean age of 59 and 18 months of follow-up were performed in our center during a 13-year period. All of them followed the same protocol. Surgical technique is described. RESULTS: All patients were arthroscopically classified as Badia's III stage...

OBJECTIVE: To determine the influence of screw configuration on the reduction and stabilization of simulated complete lateral condylar fracture. STUDY DESIGN: Randomized experimental crossover study. METHODS: A lateral condylar fracture was simulated in 18 cadaver limbs from nine horses. Each limb underwent repair with 4.5 mm diameter cortex screws, tightened to 4 Nm, in a linear and triangular configuration. Computed tomography (CT) of each repair was performed with the limbs in unloaded and loaded conditions...

A 15-year-old Cocker Spaniel was referred to for the evaluation of left forelimb lameness. Radiographic and computed tomography examinations revealed osteolysis of the proximal left third, fourth and fifth metacarpal bones and pathological fractures of the proximal left fourth metacarpal bone. Histopathological examination via bone biopsy did not provide a definitive diagnosis, and the owner elected limb-sparing surgery. The fourth metacarpal bone and digits were amputated. Subsequently, autologous bone grafts were performed on the lytic area of the third and fifth metacarpal bones...

BACKGROUND: Low bone mineral density affects 53% of women over age 65 in the US, yet many are unaware and remain untreated. Underdiagnosis of forearm osteoporosis and related fragility fractures represent missed warning signs of more deadly, future fractures. This study aimed to determine if hand radiographs could serve as early, simple screening tools for predicting low forearm bone mineral density (BMD). METHODS: We evaluated posterior-anterior (PA) hand radiographs (x-rays) and Dual-energy X-ray absorptiometry (DXA) scans of 43 participants...

INTRODUCTION: The photodynamic bone stabilization system (PBSS) was was developed in 2010, and in 2018 gained FDA approval in the United States. Given its relative novelty, our analysis sought to analyze the available literature exploring the indications, outcomes, and complications of the PBSS. METHODS: We performed a systematic review (PROSPERO registration of study protocol: CRD42022363065, October 8th, 2022). PubMed, EBSCOHost, and Google Scholar electronic databases were queried to identify articles evaluating PBSS in the treatment of pathologic or traumatic fractures between January 1 2010 and 15 October 2022...

PURPOSE: Metacarpal fractures are common injuries of the hand that often require operative repair. However, there is a paucity of data regarding the rate of reoperation and circumstances following metacarpal repair. METHODS: A retrospective review of all metacarpal fracture cases performed at a single academic institution between 2017 and 2021 was performed. All patients with isolated, acute metacarpal fractures were included for review. Data on patient demographics, fracture morphology, surgical technique, rate of early reoperation, and reason for reoperation were collected...

PURPOSE: The purpose of this study is to generate validated prediction rules for metacarpal lengths that can be applied without the need for computation tools to assist with restoration of anatomic length after fracture and utilizes only ipsilateral metacarpals. METHODS: The anatomic lengths of all hand bones in 50 hands (25 men, 25 women) were used along with linear regression subset analysis to determine which metacarpals are the most predictive of each other...

PURPOSE: Intramedullary screw fixation has emerged as a popular approach for the treatment of displaced metacarpal fractures. The purpose of this study was to investigate the functional and radiographic outcomes of a newly designed, headless noncompressive fully threaded intramedullary nail (TIMN) for the treatment of metacarpal fractures. METHODS: A retrospective chart review was performed on patients who were treated with the INnate TIMN (ExsoMed) at a single academic institution with a minimum of 1-year follow-up...

We present a novel treatment for post-traumatic arthritis of the hand and fingers using joint resurfacing with cadaveric meniscus. A 20-year-old man presented to the clinic with chronic pain and stiffness after an intra-articular fifth metacarpal fracture. Meniscus allograft, which has been used successfully in treatments for thumb carpometacarpal and radiocarpal degenerative osteoarthritis, was used to reconstruct the joint surface with complete resolution of stiffness and pain.

Scaphoid dislocation represents a rare injury with only a few case reports and limited case series reported in the literature. The majority of scaphoid dislocations result from a high-energy trauma causing hyperextension and ulnar deviation of the wrist. The severity of a scaphoid dislocation depends on the degree of periscaphoid ligamentous injury as well as the presence of concomitant injuries, such as axial carpal dissociation. The most common complication after a scaphoid dislocation is scapholunate dissociation, which emphasizes the importance of scapholunate ligament repair/reconstruction in these cases...

INTRODUCTION: Avulsion fractures of the extensor carpi ulnaris (ECU) from its insertion are rare injuries that are rarely reported in the literature. Most of the case reports detailed closed ruptures. We present avulsion fractures of the bilateral ECU from the base of the 5th metacarpal. Not much of the literature has been published in this regard. CASE REPORT: A 33 year old male presented with pain around both wrists and hands following a fall from a bike. Following evaluation and radiological investigation, he was found to have a volar Barton fracture with an undisplaced avulsed 5th metacarpal base fracture on the right side and a displaced avulsed fracture of the left 5th metacarpal base...

INTRODUCTION: "Joota Chori" is a traditional Indian wedding ritual which involves playful competition between the bride's and the groom's friends, with the aim of hiding and retrieving the groom's shoes. CASE REPORT: We describe a rare case scenario wherein an orthopedic surgeon sustained a metacarpal shaft fracture while gripping the shoe and engaging in a tussle with the groom's friends. Despite feeling a sudden snap and experiencing pain, the surgeon held onto the shoe...

Most fractures in the third metacarpal bone of equine athletes occur due to repeated cycles of high load magnitudes and are commonly generated during fast-training workouts. These repetitive loads may induce changes in the microstructure and mechanical properties that can develop into subchondral bone (SCB) injuries near the articular surface. In this study, we investigated the fatigue behaviour of local regions in SCB (near the articular surface i.e., 2 mm superficial SCB and the underlying 2 mm deeper SCB) under a simulated fast-training workout of an equine athlete...

Objective  Hamate dislocations are rare lesions of the carpus, which make their diagnosis difficult or even missed, and their management non-standardized. Case Description  We report the case of a 34-year-old victim of a high kinetic traffic accident. The initial evaluation revealed multiple fractures of both upper limbs, including a palmar fracture dislocation fracture of the hamate, without any vascular or nerve complications. Open surgical treatment via a dorsal approach allowed reduction and fixation of the hamate by temporary multiple pinning...

Background  Intramedullary screw fixation is a commonly used technique for the management of metacarpal fractures. However, compression across the fracture site can lead to unintentional shortening of the metacarpal. Questions/Purposes  Our aim was to evaluate the risk of overshortening with differing intramedullary device designs for fixation of metacarpals. Methods  The small finger metacarpal of nine fresh-frozen cadavers were included. A metacarpal neck fracture was simulated with a 5-mm osteotomy...

The purpose was to compare clinical and radiological outcomes between two fixation techniques used to treat extra-articular fractures involving the base of the thumb metacarpal: retrograde intramedullary cannulated headless screw (RICHS) and locking plate (LP). Fifty-one patients who underwent RICHS (n = 22) or LP fixation (n = 29) from January 2010 through 2020 were included in this retrospective case-control study with mean follow-up 39 months. No inter-group differences were observed comparing mean time to radiological union, grip strength, range of motion, pain severity or QuickDASH scores...

INTRODUCTION: Metacarpal fractures are common sports-related injuries, often requiring tailored treatment strategies, especially in athletes. The management of oblique diaphyseal fractures poses unique challenges due to their inherent instability. This case report discusses a non-surgical approach in treating such fractures in a professional athlete. CASE PRESENTATION: A 26-year-old professional soccer player sustained oblique diaphyseal fractures of the fourth and fifth metacarpals during training...

Fractures of the phalanges may result in a challenging complication known as malrotation, which can adversely affect the functionality of the fingers during flexion, leading to scissoring. The standard surgical approach for correcting this condition involves open corrective osteotomy and derotation, often at the level of the metacarpal, which includes the use of different techniques for osteotomy and fixation. However, postoperative complications such as finger stiffness and hardware irritation are common. To overcome these limitations, we present a novel and minimally invasive corrective osteotomy technique for malunited proximal phalanx fractures with rotational malalignment, which offers several advantages, such as accelerated rehabilitation and no prominent hardware...

PURPOSE: Hamate fractures are infrequent and often overlooked wrist injuries. Our objective is to present the Shish-Kebab method, a surgical approach utilized in the treatment of intra-articular Hamate body fractures occurring concurrently with fourth metacarpal base fractures and dislocations. METHODS: This study was conducted at a single-center using a prospective design. It included patients aged 16-65 with Kim Type IIB fractures affecting the dominant side. Patients with the same features of fracture and carpometacarpal (CMC) instability findings were divided into two groups according to the success of the closed reduction procedure...

BACKGROUND Fracture of the fifth metacarpal of the hand is due to trauma to the clenched fist. The non-displaced fracture can be treated by splinting and immobilization, but fracture dislocation requires individualized management to ensure the return of function. The Jahss maneuver for reduction of volar displaced metacarpal neck fractures involves flexion of the metacarpophalangeal and proximal interphalangeal joint at 90°, with the proximal phalanx used to reduce the metacarpal head. This report is of a 25-year-old male Italian pianist with a displaced fifth metacarpal neck fracture successfully treated by reduction using the Jahss maneuver and K-wire attachment of subchondral bone to the metacarpal...
