The purpose of the present study was to assess the results of reconstruction of the rheumatoid forefoot with arthrodesis of the metatarsophalangeal joint of the great toe, resection arthroplasty of the metatarsal heads of the lesser toes, and open repair of hammer-toe deformity (arthrodesis of the proximal interphalangeal joint) of the lesser toes when this deformity was present. ⋯ In the present study, arthrodesis of the first metatarsophalangeal joint, resection arthroplasty of the lesser metatarsal heads, and repair of fixed hammer-toe deformities with intramedullary Kirschnerwire fixation resulted in a stable repair with a high percentage of successful results at an average of six years after the procedures.

Simultaneous femoral osteotomy and total knee arthroplasty for treatment of osteoarthritis associated with severe extra-articular deformity.
In the presence of large extra-articular deformity, complex imbalance of the collateral ligaments may result if standard techniques of soft-tissue releases and intra-articular bone resection are used during total knee arthroplasty. The purpose of this paper is to review our experience with simultaneous corrective osteotomy and total knee arthroplasty for the treatment of severe extra-articular femoral deformity associated with ipsilateral osteoarthritis of the knee. ⋯ Simultaneous femoral osteotomy and total knee arthroplasty is a technically difficult but effective treatment for patients with severe femoral deformity associated with ipsilateral osteoarthritis of the knee. We recommend that the femoral osteotomy site be secured with a plate or a locked intramedullary nail, depending on the location of the deformity and the subsequent osteotomy.

Comparative StudyElectromyographic and gait analysis of forty-three patients after rotationplasty.
Rotationplasty is considered to be a treatment option for patients who have had a primary malignant bone tumor of the distal part of the femur or the proximal part of the tibia. The present study was performed to evaluate the muscle activity, the kinetics (range of motion of the hip and knee joints), and the kinematics (joint moments) after rotationplasty and to determine whether there was an association between these parameters and the functional outcome. ⋯ The results of the electromyographic and gait analyses demonstrated good functional restoration of gait following rotationplasty.

Comparative StudyCiprofloxacin inhibition of experimental fracture healing.
Fluoroquinolones, such as ciprofloxacin, have an adverse effect on growing cartilage and endochondral ossification in children. This study was carried out to determine whether ciprofloxacin also has an adverse effect on the healing of experimental fractures. ⋯ These data suggest that experimental fractures exposed to therapeutic concentrations of ciprofloxacin in serum demonstrate diminished healing during the early stages of fracture repair. The administration of ciprofloxacin during early fracture repair may compromise the clinical course of fracture-healing.

Comparative StudyLong-term disability and return to work among patients who have a herniated lumbar disc: the effect of disability compensation.
Low-back problems are one of the most frequent reasons for disability compensation claims by workers. However, the effect of Workers' Compensation status on the long-term outcome for workers with sciatica has not been studied in detail, to our knowledge. Therefore, we believe that it is important to describe the long-term outcomes for patients who have herniation of a lumbar disc and sciatica according to the Workers' Compensation status at the time of the preoperative consultation. ⋯ Even after adjustment for the initial treatment of the sciatica and for other clinical factors, patients who had been receiving Workers' Compensation at baseline were more likely to be receiving disability benefits and were less likely to report relief from symptoms and improvement in quality of life at the time of the four-year follow-up than patients who had not been receiving Workers' Compensation at baseline. Nonetheless, most patients returned to work regardless of their initial disability status, and those who had been receiving Workers' Compensation at baseline were only slightly less likely to be working after four years. Whether or not they had been receiving Workers' Compensation at baseline, patients who had been managed with an operation reported greater relief from symptoms and improvement in functional status at the time of the four-year follow-up compared with patients who had been managed nonoperatively, even though the outcomes with regard to disability and work status in these two groups were comparable.
