Carpometacarpal (CMC) fracture-dislocations of the fifth ray are common. For chronic injuries, Dubert proposed combining resection arthroplasty of the base of the fifth metacarpal (M5) with synostosis with the fourth metacarpal (M4). Our aim was to evaluate the results of this procedure. Between 1994 and 2014, 7 men and 1 woman with an average age of 36 years (range, 27 to 45) were operated on. The right hand was involved in 6 of the 8 cases. All patients had symptomatic osteoarthritis secondary to isolated articular malunion and subluxation of the 5th CMC joint...

In the published literature there are controversial data to the biomechanical stability of monocortical comparing to the bicortical fixation of metacarpal fractures. The aim of this study was to compare the biomechanical stability of monocortical and bicortical locking osteosynthesis in quasi-static and dynamic 4-point bending tests of composite third metacarpal bone (4th Gen third metacarpal, Sawbones, Malmö, Sweden) fixed with 7-hole locking plate (XXS System, Biotech-Ortho, Wright, Memphis, TN). The tests to determine quasi-static yield and bending strength as well as fatigue strength were conducted in 4 groups of 10 samples after creating standardized mid-shaft transverse osteotomies using a diamont belt grinder (0...

BACKGROUND: It is possible that some hamate hook fractures are not diagnosed or treated, thereby affecting the study of their natural history. Study of the prevalence of incidental hamate hook fractures, nonunions, and other abnormalities on computed tomography (CT) ordered for another reason could document a subset of undiagnosed and untreated hamate hook fractures which might change our understanding about the natural history. METHODS: Reports of 2489 hand, wrist, and forearm CT scans for hamate hook abnormalities were searched...

Helen Liley, Helen Davies, Elwyn Firth, Thor Besier, Justin Fernandez
Fatigue failure of bones of the metacarpo-phalangeal (fetlock, MCP) joint is common in thoroughbred racehorses. Stresses within the fetlock joint cartilages are affected by the morphology of the third metacarpal bone (MC3) and proximal phalangeal bone, and the steepness of the median sagittal ridge of MC3 is believed to be associated with fracture. This study investigated the influence of the steepness of the sagittal ridge on cartilage stress distribution using a finite element model of the joint. Changes to the steepness of the sagittal ridge were made by applying a parabolic function to the mesh, creating four different models with sagittal ridge angles ranging from 95° to 105°...

Metacarpal fractures account for 10% to 35% of all pediatric hand fractures. Pediatric metacarpal fractures commonly occur in patients aged 13 to 16 years, with most injuries sustained during sports activities. Pseudoepiphyses can be confused with metacarpal fractures; however, a careful physical examination can help physicians distinguish the two. Thumb metacarpal base fractures that involve the physis warrant special attention. Thumb metacarpal base fractures with lateral metaphyseal fragments and pediatric Bennett fracture variants (Salter-Harris type III and type IV fractures) are unstable and require surgical management...

The aim of our study was to evaluate an original surgical technique for the treatment of fifth metacarpal neck fractures: elastic retrograde intramedullary percutaneous pinning (ERIPP). From January 2014 to January 2016, patients with a fifth metacarpal neck fracture with greater than 30° volar displacement and/or clinodactyly were included. All patients underwent an ERIPP procedure. With this technique, K-wires are used as joysticks to assist reduction when the Jahss maneuver is insufficient. Clinical evaluation incorporated the DASH score, range of motion and grip strength at 3months...
