BACKGROUND Conventional technique of valgus osteotomy of the proximal femur involves removal of a partial or full thickness lateral based wedge from the peritrochanteric region. The purpose of this article is to describe a novel technique of valgus subtrochanteric osteotomy for proximal femur nonunion. METHODS 11 patients with proximal femur nonunions {intracapsular fractures--7, extracapsula...

OBJECTIVE To determine whether knee arthrodesis with simultaneous lengthening using the Ilizarov method for a nonreconstructable knee joint with bone loss and infection is a successful salvage procedure. DESIGN Retrospective review of patients. SETTING University hospital-based orthopaedic practice. PATIENTS From 1999 to 2001, 4 consecutive patients with a nonreconstructable knee joint, b...

Permanent dislocation of the patella in adults is a rare condition that presents with complete irreducible lateral dislocation of the patella, combined with secondary changes, such as valgus deformity and leg-length discrepancy. Because these secondary changes cannot heal spontaneously after skeletal maturation if left untreated, the patients frequently possess pathology not limited to the knee...

Long distance, overground locomotion in the dog was observed and analyzed using the two dimensional gait diagram method. Though the velocity of locomotion chosen by the animals over a 1,000 m course varied, a preferred speed generally emerged and was used during most of the experiment. This animal-specific preferred overground velocity was strongly correlated with the animal's limb lengths, and...

Leg-length discrepancy greater than 2 to 2.5 cm can potentially have an adverse effect on our walking and standing mechanisms and requires proper correction involving surgical treatment. However, for minor leg-length discrepancy in childhood, decision making for the indications for and timing of epiphysiodesis is difficult because of unpredictable final discrepancy. The purpose of this study wa...
