Follow-up results 17 years after resection arthroplasty of the great toe.
Resection arthroplasty of the first metatarsophalangeal joint is a well-known operation. The follow-up results more than 17 years after arthroplasty for hallux valgus are reported and discussed. Between 1971 and 1980, 335 resection arthroplasties were performed on 205 patients. ⋯ The average hallux valgus angle was 23 degrees at follow-up and 34 degrees prior to surgery. The unacceptably high rate of hallux valgus relapse, especially due to a high intermetatarsal angle, emphasizes the unsatisfactory long-term results of the resection arthroplasty. We now recommend this operation for older patients only, and a differentiated approach using reconstructive procedures according to the clinical and radiographical situation for younger patients.

Comparative StudyRadial and lumbar bone mineral density after wrist synovectomy in rheumatoid arthritis. A minimum 2-year follow-up in 10 unilaterally operated patients.
Bone mineral density (BMD) of both radii and lumbar vertebrae was measured by single-photon absorptiometry and dual X-ray absorptiometry, respectively, before and 2.1-4.8 years after a unilateral wrist synovectomy in 10 patients with rheumatoid arthritis. Radial BMD on the operated side significantly increased after synovectomy, while that on the non-operated side did not change. ⋯ The grip strength of the operated side increased significantly after synovectomy, while there were no changes in the grip strength on the non-operated side. These findings suggest that wrist synovectomy results in pain relief and improves use, thereby increasing the BMD of the operated radius.

Comparative StudyEffects of percutaneous and conventional plating techniques on the blood supply to the femur.
A cadaveric arterial injection study was performed to study the effects of percutaneous and conventional surgical plating techniques on femoral vascularity. Sixteen-hole dynamic condylar screw and condylar buttress plates were applied on the proximal and distal shafts, respectively, of intact femora in ten human cadavers. On one side, the plate was inserted using a lateral conventional plate osteosynthesis (CPO) technique with elevation of the vastus lateralis muscle to expose the shaft. ⋯ The pattern of periosteal filling of the injected dye was analyzed. The MIPPO technique maintained the integrity of the PAs and exhibited superior periosteal perfusion. The results of this study indicate that the MIPPO technique maintains femoral vascularity and perfusion better than the CPO technique.

We present a case of a Galeazzi-type of fracture dislocation with an irreducible distal radioulnar joint. This is illustrated by intraoperative pictures which may assist others who find themselves faced with this injury.

Measurement of skeletal flow with positron emission tomography and 18F-fluoride in femoral head osteonecrosis.
Positron emission tomography (PET) with 18F-fluoride was utilized to determine the regional blood flow to the femoral head in early osteonecrosis. Five patients with a history of unilateral hip trauma and a normal contralateral side were selected. ⋯ A minimum flow of 0.04 ml/min/ml was measured in one patient whose affected femoral head healed conservatively. Our preliminary study indicates that this type of highly technical investigation appears feasible in clinical practice and permits prediction of the outcome depending upon regional skeletal flow measurements in vivo.
