Total hip arthroplasty for primary osteoarthritis in patients fifty-five years of age or older. An analysis of the Finnish arthroplasty registry.
According to the long-term results obtained from the Scandinavian arthroplasty registries, cemented total hip replacement has been the treatment of choice for osteoarthritis of the hip in elderly patients. The aim of the present study was to analyze population-based survival rates of the cemented and cementless total hip replacements performed for primary osteoarthritis in patients fifty-five years of age or older in Finland. ⋯ Therapeutic Level III. See Instructions to Authors for a complete description of levels of evidence.

Distal tibial reconstruction with use of a circular external fixator and an intramedullary nail. Surgical technique.
Distal tibial reconstruction with use of an external fixator when there is bone loss, limb-length discrepancy, and/or ankle instability is associated with many problems. The technique of limb-lengthening, ankle arthrodesis, and segmental transfer over an intramedullary nail has been introduced to overcome these problems. The present study investigates this combined technique. ⋯ The combined technique is an improvement over the classic external fixation techniques of distal tibial reconstruction with ankle arthrodesis. It reduces the duration of external fixation, thus increasing patient acceptance, and it is associated with a low complication rate facilitating more rapid rehabilitation.

There have been few prospective studies that have documented the outcome of surgical treatment of hallux valgus deformities. The purpose of this investigation was to evaluate the effect of operative treatment of hallux valgus with use of a proximal crescentic osteotomy and distal soft-tissue repair on the first metatarsophalangeal joint. ⋯ A proximal crescentic osteotomy of the first metatarsal combined with distal soft-tissue realignment should be considered in the surgical management of moderate and severe subluxated hallux valgus deformities. First ray mobility was routinely reduced to a normal level without the need for an arthrodesis of the metatarsocuneiform joint. Plantar gapping is not a reliable radiographic indication of hypermobility of the first ray in the sagittal plane.

rhBMP-12 accelerates healing of rotator cuff repairs in a sheep model.
The success rate of rotator cuff repairs is variable. This study was performed to evaluate the ability of recombinant human bone morphogenetic protein-12 (rhBMP-12), administered in several carriers, to accelerate healing in a sheep model of rotator cuff repair. ⋯ Delivery of rhBMP-12 in several sponge carriers has the potential to accelerate healing of rotator cuff repairs. Accelerated repair may allow shorter rehabilitation and an earlier return to occupational and recreational activities.

Multicenter StudyOutcome after surgery for the treatment of hip fracture in the extremely elderly.
As a consequence of changes in population demographics, the extremely elderly represent one of the fastest growing groups in Western society. Previous studies have associated advanced age with increased mortality after hip fracture; however, this finding has not been consistent. ⋯ Although the extremely elderly exhibited a higher prevalence of prefracture indicators of poor outcome, statistical control for these case-mix variables showed further age-related deterioration in survival and outcomes after surgery for the treatment of a hip fracture.
