Metacarpal lengthening was performed by callus distraction in six children with brachydactyly. Four of the patients were girls and two were boys, with ages ranging from 10 to 14 years (mean age: 12 years). Four of the patients had brachydactyly resulting from injury to the hand and damage to the epiphysis related to infection, while the other two had congenital brachymetacarpia. Two patients ha...

Objectives. We evaluated the results of digital lengthening by distraction and second-stage bone graft. Methods. We treated finger deficiency of 201 digits in 104 patients (68 males, 36 females) by digital distraction and second-stage bone graft. The distraction was performed with a rate of 1 mm/day (for the first ten days) and 0.5 mm/day followed by using a self-designed bilateral tubal-helica...

Materials and methods The reconstructed site was the humerus in 15 cases, the radius, the ulna or the wrist joint in 22 cases, carpal or metacarpal bone in 52. The etiologies consisted of three traumatic bone defects, 13 traumatic nonunions of long bone, two osteonecroses of the humeral head, eight osteomyelitis, nine case after resections of bone tumor, two congenital pseudoarthroses of the ul...

Introduction Myxoid chondrosarcoma is a distinct subtype of chondrosarcoma with several key differences from conventional chondrosarcoma of bone. Our review of the literature and have found that myxoid chondrosarcoma is typically extra skeletal in presentation. Very few cases of myxoid chondrosarcoma of the hand or wrist have been reported and they were extra skeletal in presentation [1-10]. We...

Stress fractures of the third metacarpal bone (McIII) are a common cause of lameness in Thoroughbred racehorses. The most commonly described location is the mid-dorsolateral cortex (Copelan 1979; Richardson 1984, 1999; Stashak 1987; Stover et al. 1988; Cervantes et al. 1992; Pilsworth and Shepherd 1997; Stover 1998; Sullins 1998), but they also occur distally and proximally in the dorsal cortex...

Capuchin monkeys present a wide variety of manipulatory skills and make routine use of tools both in captivity and in the wild. Efficient handling of objects in this genus has led several investigators to assume near-human thumb movements despite the lack of anatomical studies. Here we perform an anatomical analysis of muscles and bones in the capuchin hand. Trapezo-metacarpal joint surfaces ob...
