Analysis of plantar loading parameters pre and post surgical intervention for hallux vargus.
INTRODUCTION:: The purpose of the study was to compare range of motion (ROM) and plantar loading parameters pre and post surgical intervention for hallux valgus (HV). Fifteen female patients volunteered for the study, providing 27 feet with a diagnosis of moderate or severe HV deformity (greater than 26 degrees HV angle). All participants were screened by the same orthopaedic surgeon to ensure that no other foot deformities or neuromuscular diseases were present that would alter lower extremity biomechanics. ⋯ Dorsiflexion ROM for the MP joint were decreased post surgically but were still adequate for gait (Hetherington et al., 1990). Loading variables indicated that, post surgically, the foot was loaded more laterally with less load on the hallux. Further research is needed to assess if the lateral loading pattern continues long term after Chevron-Aikin Osteotomy surgical correction for HV.

Comparative Study
Differences in physician compensation for cardiovascular services by age, sex, and race.
The purpose was to determine whether physicians receive substantially less compensation from patient groups (women, older patients, and nonwhite patients) that are reported to have low rates of utilization of cardiovascular services. Over an 18-month period we collected information on payments to physicians by 3,194 consecutive patients who underwent stress testing an 833 consecutive patients who underwent percutaneous coronary angioplasty at the Yale University Cardiology Practice. ⋯ Similar differences were observed for stress testing. These associations were largely explained by differences in insurance status.

Knee injuries in children and adolescents often involve the growth plate (physis), as well as the adjacent bony areas of the femur, tibia, or patella. Young patients who have injured knees require careful clinical and radiographic assessment to determine the extent of their injuries, with specific management to minimize the potential for growth arrest and resultant deformity. This article discusses distal femoral physeal, proximal tibial physeal, tibial eminence, patellar sleeve, and tibial tubercle fractures in skeletally immature patients.
