Rupture of the deep transverse metacarpal ligament (DTML) can result in pain, impaired grip strength, and undermine functional performance of the hand. We describe the case of a patient whose right hand came into contact with a boat propeller. He sustained a complete disruption of the DTML between the second and third ray in addition to soft tissue injury and open metacarpal fractures. Although other techniques describe a reconstruction of the DTML, our technique describes an adjunctive technique that strongly augments the A1 pulley reconstruction and nullifies the requirements of palmaris longus graft...

We present two cases of pathologic fractures extended to the metacarpal head related with enchondromas at the metacarpal neck treated by surgery. The timing of surgery varied between the two cases. The first was operated without delay, using tumor curettage and β-TCP (tricalcium phosphate) packing in the cavity, followed by internal fixation of the fracture using a screw and Kirshner wires. In the second case, tumor curettage and β-TCP packing was performed after fracture union. Favorable clinical outcomes were obtained for both cases...

BACKGROUND: We compared 3 surgical approaches to the MP joint: a dorsal extensor tendon-splitting approach, a dorsal extensor tendon-reflecting parasagittal approach, and the volar A1 pulley approach. We quantitatively compared each of these approaches by measuring the amount of articular cartilage exposed on the base of the proximal phalanx. We hypothesize that visualization of the articular cartilage of the proximal phalangeal base is enhanced with the volar approach. METHODS: The MP joints of the 32 available digits were randomly assigned to 1 of 3 surgical approaches: extensor tendon splitting (A), extensor tendon reflecting (B), or volar approach (C)...

INTRODUCTION: The treatment of the flexor tendon adhesions following phalanx and metacarpal fractures, in closed or open injuries, is a great challenge for the hand surgeon. The outcomes are often poor, because of the severity of the lesion and the aggressiveness of the surgical procedure of the secondary tenolysis. MATERIALS AND METHODS: The authors describe the technical findings and the results of a new mini-invasive tenolysis in order to treat the adhesions in zone 1 and 2 of the fingers, following phalangeal and metacarpal fractures...

BACKGROUND: During the surgery for a distal radius fracture, we encountered a large anomalous muscle lying across the distal radius. The muscle was identified as a flexor carpi radialis brevis muscle (FCRB), based on its location, function, and innervation. This experience led us to clarify its prevalence in living subjects and alert surgeons of its presence. METHODS: We reviewed wrist MRI scans of 515 hands of 379 patients with carpal tunnel syndrome (CTS). The prevalence of the FCRB was calculated...

A detailed histopathological study of the distal third metacarpal bone of Thoroughbred racehorses was undertaken to characterize lesions observed previously on magnetic resonance imaging (MRI). The bones were selected and grouped on the basis of MRI features. Representative sections in different planes were processed for histopathology. All lesions observed in the articular cartilage (AC) and subchondral bone (SCB) were recorded and graded with a scoring system, based partially on the Osteoarthritis Research Society International grading system...

BACKGROUND: Management of Bennett fractures has been controversial. Early reports supported closed reduction and casting with or without percutaneous pinning. Later, open reduction and internal fixation was advocated. The purpose of this article is to assess the surgical treatment using a direct volar approach. METHODS: Between March 2008 and December 2014, 21 patients with intra-articular first metacarpal fractures displaced more than 1 mm were operated on using a direct volar approach...

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°...
