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.

Comparative StudyBlood levels of active metabolites of vitamin D3 in fracture repair in humans. A preliminary report.
Blood levels of the active metabolites of vitamin D3, 25-hydroxycholecalciferol [25(OH)D3], 1,25-dihydroxycholecalciferol [1,25(OH)2D3] and 24,25-dihydroxycholecalciferol [24,25(OH)2D3] were determined in seven patients. Two subjects suffered from delayed union of tibial fractures; one showed a delayed union after a proximal tibial osteotomy; one patient suffered from bilateral femoral neck fractures, of which one failed to unite and the other united late; two patients had multiple fractures that united normally; and one patient exhibited staged bilateral femoral neck fractures whose occurrence was separated by a short interval and which united without undue delay. ⋯ A decrease in 1,25(OH)2D3 levels was noted in only two patients. We postulate that these changes reflect the consumption of these metabolites during healing at the fracture site.

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.

Pigmented villonodular synovitis is a benign disease of the synovial membrane of joints, tendon sheaths, or bursae, which nevertheless can cause marked local destruction. Its diagnosis is often delayed because complaints and symptoms are nonspecific. Familiarity with the disease may ensure an earlier diagnosis and consequently early onset of therapy, which may prevent serious damage. ⋯ Findings possibly suggestive of pigmented villonodular synovitis include hemarthrosis, soft tissue swelling, radiological evidence of cyst formation at a distance from the weight-bearing area of a joint, an increased triglyceride concentration, and a positive bone scan. A normal appearance on arthroscopy does not rule out the disease. Therapeutic results are better in the localized than in the diffuse form of the disease.

Femoral shaft perforation at arthroplasty: to treat or not to treat.
Femoral shaft perforation at total hip arthroplasty is a complication that is being noted more frequently, and it is often associated with femoral shaft fracture below the prosthesis. This study examines the anatomic and biomechanical effects of femoral shaft perforation at arthroplasty, and the effects of supporting the perforated bone with Partridge plates and bands. ⋯ Testing the bone models to failure in tensile mode showed that the perforations weakened the bone and that the Partridge plates and bands decreased the weakening effects of the perforation. The strengthening effect of the Partridge plates and bands on the bone with a perforation, allied with the presence of an internal splint in the event of a fracture through the perforation, suggests the benefit of using Partridge plates and bands if a cortical perforation is found at arthroplasty and revision is not feasible.
