PURPOSE Metacarpal fractures are common in hand surgery. Metacarpal shortening ranging from 2 mm to as much as 10 mm has been deemed acceptable in the literature. We examined the effect of metacarpal shortening on interosseous muscle architecture and predicted force production capacity based on the standard muscle length-tension curve (commonly known as the Blix curve). METHODS The dorsal int...

Suday, Sptem er 5, 2016 CONCLUSION: Dorsal bridge plate fixation of distal radius fractures restores preoperative physiologic measures of the radius, ulna, and carpus. No significant carpal translocation occurred during distal bridge plate fixation to the 2nd or 3rd metacarpal bone. While additional studies are needed, fixation to the 2nd metacarpal is preferred as it does not translocate the w...

Among 227 chronic renal disease patients, micrometer caliper radiogrammetric measurements of the second metacarpal at midshaft showed the right metacarpal to be larger (with greater bone area) and with a greater cortical area than the left second metacarpal, both in 208 right-handed individuals and in 19 left-handed individuals. This direction of asymmetry was individually characteristic of the...

Introduction: Failures in total wrist arthroplasty (TWA) can be most often attributed to three main factors: improper prosthesis centering, component loosening and soft tissue imbalance (1). Of these, one of the most often reported complications is metacarpal loosening with dorsal protrusion of the stem (2). Abnormal load transfer through the prosthesis is believed to contribute to component lo...

offerosclerosis and osteoporosis are major causes of morbidity and mortality in postmenopausal women and have been suggested to be associated. No study has examined whether progression of atherosclerotic calcification is associated with bone loss. In the present study, we examined progression of aortic calcification, diagnosed by radiographic detection of calcified deposits in the abdominal aor...

Metacarpal fractures were more common than metatarsal fractures in this retrospective study of 37 dogs. Fractures of one metacarpal or metatarsal bone occurred in 24 per cent of the dogs, two metacarpal bones in 16 per cent, three metacarpal or metatarsal bones in 19 per cent, and four metacarpal or metatarsal bones in 41 per cent. Eighty-seven per cent of the dogs with fractures of four bones ...

BACKGROUND Metacarpal fractures are common in football players and lead to time away from competition, but current operative treatment data is limited. The purpose of this study was to examine demographics and outcomes of football players who underwent operative fixation for metacarpal fractures. METHODS Retrospective review from 2009 to 2012 of any football player surgically treated at one i...

We present two patients with a displaced fracture of the small finger metacarpal base, where the shaft of the small finger metacarpal was wedged between the bases of the ring and small finger metacarpals. The striking appearance on radiographs led to initial recommendations for surgery, but both patients preferred non-operative treatment and did well in the short term without surgery

OBJECTIVE To report long‐term follow‐up outcomes on 4 patients who underwent Osteochondral Autologous Transplantation (OAT) for isolated cartilage defects of the metacarpal (MP) head. CONCLUSION Long‐term results suggest that OAT may be a viable surgical option for treatment of cartilage defects of the metacarpal head. METHODS IRB approval was obtained. Six to 8mm grafts obtained from the knee ...

Formulae for the estimation of stature from metacarpal lengths are presented. Two samples of metacarpal specimens were employed in the analysis: one of 212 individuals from the Terry Collection, and one of 55 modern males, all of whom had measured statures. One measurement, the midline length, was taken on each metacarpal. Stature was regressed on the basis of the metacarpal length to derive eq...
