Iliopsoas tenotomy at the lesser trochanter versus at the pelvic brim in ambulatory children with cerebral palsy.

Background: Progressive hip flexion deformity is a common problem in ambulatory children with spastic cerebral palsy, causing static and dynamic deformity. The iliopsoas muscle is recognized as a major deforming force in the development of this problem. Many clinicians address this problem by lengthening the iliopsoas, either in an intramuscular location at the pelvic brim or by complete tenotomy at the lesser trochanter.

Performance characteristics of ultrasound of the knee in a general radiological setting.

Ultrasound of the musculoskeletal system is an attractive imaging modality due to the lack of ionising radiation, cost and ease of availability. A role has been established in the shoulder and pediatric hip but not in the knee. Ultrasound studies of the knee performed at six general radiological practices without established musculoskeletal expertise were compared with clinical examination in 56 patients.

Positive leukocyte and negative bone scintigraphy in extensive arthroplasty infection.

An 85-year-old male resident of a nursing home presented after a fall with a painful left hip, confusion, and fever. He had multiple medical problems including severe vascular disease and poor vision as a result of macular degeneration. An Austin Moore left hip prosthesis had been inserted for a fractured femoral neck several years before.
