Children with limited or no ability to ambulate frequently sustain fragility fractures. Joint contractures, scoliosis, hip dysplasia, and metallic implants often prevent reliable measures of bone mineral density (BMD) in the proximal femur and lumbar spine, where BMD is commonly measured. Further, the relevance of lumbar spine BMD to fracture risk in this population is questionable. In an effor...

BACKGROUND Few studies have looked into age-related variations in femur shape. We hypothesized that three-dimensional (3D) geometric morphometric analysis of the distal femur would reveal age-related differences. The purpose of this study was to show that differences in distal femur shape related to age could be identified, visualized, and quantified using three-dimensional (3D) geometric morph...

Osteoporosis (OP) in spinal cord injury (SCI) patients is a secondary process in which numerous factors are involved. Diagnosing OP and the threshold for fractures in this population, based on bone mineral density (BMD) measured by double energy X-ray absorptiometry (DXA), is still a challenge. The aim of this study was to evaluate bone mineral loss by DXA, its relationship with body compositio...

BACKGROUND There is no accepted landmark for the mechanical axis of the femoral axis in sagittal plane in conventional total knee arthroplasty. METHODS As palpable anatomic landmarks of the femur, lateral epicondyle, and anterior margin of the greater trochanter were identified. The line connecting these two landmarks was defined as the "palpable sagittal axis". The mechanical axis of the fem...

Trifocal femur fractures are those of the femoral neck, diaphysis, and distal femur. These high-energy injuries predominantly occur in young people with the potential for long-term complications and disability. We present the cases of two men who were treated with proximal dynamic hip screws and distal periarticular locking plates to effectively manage trifocal femur fractures. Our cases have s...

BACKGROUND Distal femur wedge osteotomies for varus or valgus alignment of the lower extremity could be done in either uniplanar or biplanar fashion.Union time and stability of the osteotomy site has been considered important in this anatomic region. In this study, clinical and radiographic findings of biplane distal femur osteotomy were reported. METHODS Clinical, functional, and radiologica...

The patient was a 27-year-old man currently serving in the military who was evaluated by a physical therapist in a direct-access mode of care for a chief complaint of worsening left distal medial thigh pain. Given the traumatic mechanism of injury, worsening symptoms, and the presence of a painful, firm mass in the left distal medial thigh region, the physical therapist ordered radiographs of t...
