Etidronate does not suppress periprosthetic bone loss following cemented hip arthroplasty.

Periprosthetic bone loss after arthroplasty may threaten prosthesis survival. The current study investigated the effect of etidronate therapy on periprosthetic, contralateral hip, and spine bone mineral density (BMD) in a one-year, prospective, randomized, double-blind study on 46 patients after cemented hip arthroplasty. BMD was measured with dual-energy X-ray absorptiometry (DXA). There were no significant differences between mean BMD measurements of the etidronate and placebo groups, with the exception of the mean percent change in the spine at six months and 12 months and in Gruen zone 3 at six months; in all three cases, the etidronate group had significantly greater mean values. These findings suggest that cyclic etidronate therapy has no significant effect in suppressing periprosthetic bone loss following cemented hip arthroplasty.

Patella fractures associated with injuries of the knee ligament.

Concurrent fractures of the patella and knee ligament ruptures are rare. From September 1985 to November 1989, 112 fractures of the patella were treated operatively at the Department of Traumatology at Celje General Hospital. In six patients (5%), associated badly injured ligaments of the knee joint were noted. During the operation, osteosynthesis of the patella was performed after the injured ligaments had been reconstructed. It is essential to examine the knee ligaments under general anesthesia before performing osteosynthesis of the patella. We have found no reports on this uncommon injury in the literature.

[Bridging an extensive bone defect with cortico-spongious transplants in femoral fracture caused by gunshot injury].

The treatment of a 12-cm bone defect after shotgun fracture of the femur is described. Semitubular corticospongious bone grafts from both iliac crests, 6 cm long and 0.8 cm wide, were tied into two bundles with an absorbable suture and were laid successively into the diaphyseal defect. With another absorbable suture the bundles were anchored to the condylar 95-deg plate. Two months later the condylar plate was removed and an external fixator placed because of inflammation; the bone implants survived. By 18 months after the injury the bone defect was cured, no inflammation was present, and the patient was able to walk with full weight bearing. Four conditions have to be fulfilled in the treatment of an open comminuted fracture with soft tissue defect: thorough necrectomy, rigid fixation, bone grafting and improvement of the blood supply by means of a microvascular musculocutaneous flap.
