The polymorphonuclear leukocyte: has it a role in fracture healing?
The aim of the present study was to assess whether the presence of polymorphonuclear leukocytes in the first stage of fracture repair was of any importance. In anesthetized male Wistar rats, a transverse osteotomy was performed at midshaft in one femur and immediately stabilized by an intramedullary Kirschner nail. The animals were allowed unprotected weight bearing immediately. ⋯ There were no differences in the amount of callus measured or in radiological healing. However, there was a significantly higher bending moment in femurs from animals treated with ANS than in those given NSS (P less than 0.02). No differences were observed in rigidity or total energy absorption.

Case ReportsIncomplete avulsion of the femoral attachment of the posterior cruciate ligament with an osteochondral fragment in a twelve-year-old boy.
Isolated avulsion of the posterior cruciate ligament from the femoral attachment of the knee as a hyperextension injury is rare. We saw a young child with an incomplete avulsion of the posterior cruciate ligament that occurred after a blow to the anterior tibial surface of a flexed knee; the child revealed a lack of knee extension due to a pinch of the osteochondral fragment connected to the anterior band of the posterior cruciate ligament in the knee joint. Arthroscopic extirpation of a fragment was undertaken.

Arthrography of the wrist joint as a dynamic examination aids in confirming lesions of interosseous ligaments of the triangular fibrocartilage complex and soft tissue. The results of arthrography in 185 wrists, classified according to age of patients and pathological disorders with or without trauma demonstrate mostly post-traumatic discus lesions in younger patients. ⋯ Pathological changes of biomechanics of the hand and wrist are noticed more often and consequently are treated surgically. Arthrography of the wrist joint is a valuable means of diagnostic imaging.

The incidence of fractures of the proximal femur and the distal radius in Tottori prefecture, Japan.
We report the incidence of proximal femur and distal radius fractures in Tottori prefecture, Japan. In 1986 and 1987, 573 proximal femoral fractures and 1576 distal radial fractures were registered in this district. The age- and sex-specific incidence rates of these two fractures are lower among Japanese than among European or North American whites, according to previous reports. Thus, it was concluded that the incidence rates of these two fractures are lower in Japanese than in Caucasians.
