Randomized Controlled Trial Clinical TrialSlotted versus non-slotted locked intramedullary nailing for femoral shaft fractures.
Experimentally, two slotted nails, the Grosse-Kempf nail and the AO/ASIF universal femoral nail, were compared to the non-slotted Grosse-Kempf nail and control bone using a cadaver femoral osteotomy. The stiffnesses and strengths of the osteotomies fixed with slotted nails in 10-30 degrees torsion were 6-8% and the values of non-slotted nails 40% of control bone. The maximal moments were 14-18% and 48%, respectively. ⋯ Four complications in the slotted nail group and three in the non-slotted nail group were considered to be independent of the choice of nail and did not affect the end result. Three splinterings of the distal fragment, one resulting in a change of the osteosynthesis implant to a condylar plate, were considered to result from the high stiffness of the non-slotted nail. Osteosynthesis of femoral shaft fractures using slotted nails has not resulted in healing disturbances, which could be accounted for by the high torsional elasticity of the nail; there seems to be no indication for high-stiffness nails in femoral fractures.

Three- to five-year results with the cementless Harris-Galante acetabular component used in hybrid total hip arthroplasty.
In this paper we present our 3- to 5-year results after hybrid total hip replacement using the cementless porous coated Harris-Galante acetabular component and the cemented Griss femoral component in 39 patients with 40 implantations. Postoperatively, mild to moderate pain was experienced by 16.1% of patients, mostly following hard activity. A slight to moderate limp occurred in 24.2%. ⋯ The postoperative range of motion was increased in 93.9%. Radiographically, none of the acetabular or femoral components had to be classified as unstable. Only one acetabular component displayed complete (i.e., along all interface zones) radiolucency and was therefore classified as possibly unstable.

Case ReportsTraumatic hemipelvectomy. A case report and comments on associated injuries.
The twenty-fifth reported case of survival following traumatic hemipelvectomy is presented. Our patient is the fourth female survivor and the second who escaped associated injuries to either the genito-urinary system or the rectum.

Intra-articular injections and articular cartilage metabolism. An experimental study in rabbits.
We studied the effects of repeated intra-articular injections of sterile 140 mM NaCl solution on articular cartilage in adult rabbits. After 20 injections into the knee joints over a period of 4 weeks, chondrocyte glucosaminoglycan synthesis was evenly reduced in all cartilage layers, accompanied by a significant proteoglycan depletion of the matrix which was most marked in the superficial half of the cartilage. ⋯ Our data underline the need for a clear-cut indication for intra-articular injections. The microtrauma caused by injection, in conjunction with the introduction of a carrier solution into the joint, may, at least when repeated at short intervals, lead to measurable damage to the articular cartilage.

Case ReportsIdiopathic Charcot's arthropathy. Report of one case.
The authors describe a case of idiopathic Charcot's joint in a 67-year-old lady. The diagnosis was made after a careful screening that ruled out all the common causes, known so far, of Charcot's joint.
