BACKGROUND Late-onset tibia vara (Blount disease) can be difficult to treat because of frequent morbid obesity and associated deformities, including distal femoral varus, proximal tibial procurvatum, and distal tibial valgus, that contribute to lower extremity malalignment. We present a comprehensive approach that addresses all components of the deformity and allows restoration of the anatomic ...

OBJECTIVE Although it is a cause of osteoarthritis (OA) in animal models, laxity in human knee OA has been minimally evaluated. Ligaments become more compliant with age; whether this results in clinical laxity is not clear. In theory, laxity may predispose to OA and/or result from OA. Our goals were to examine the correlation of age and sex with knee laxity in control subjects without OA, compa...

background: the aim of this study is to evaluate the geometry of the distal femur and the proximal tibia in the osteoarthritic knee using 3d reconstructive ct scan imaging. methods: 449 patients with knee osteoarthritis were treated surgically in our center with patient-specific technology total knee arthroplasty. preoperatively, all the patients underwent a ct scan according to a standard prot...

OBJECTIVES To evaluate valgus subtrochanteric osteotomy for the treatment of trochanteric non-union. METHODS A retrospective study of cases series. From 1998 September to 2009 January, seventeen (17) cases with a diagnosis of non-union of trochanteric fracture were re-operated by the hip group of the Ortophaedic And Traumatology service of the Hospital Geral de Goiania (HGG). The patients pre...

AIMS The aim of this study was to report a single surgeon series of consecutive patients with moderate hallux valgus managed with a percutaneous extra-articular reverse-L chevron (PERC) osteotomy. PATIENTS AND METHODS A total of 38 patients underwent 45 procedures. There were 35 women and three men. The mean age of the patients was 48 years (17 to 69). An additional percutaneous Akin osteotom...

BACKGROUND Members of the Maasai tribe spend their days either barefoot or wearing traditional shoes made from recycled car tires. Although they walk long distances (up to 60 km) daily, they do not generally experience foot ailments. Here, we compared parameters associated with the feet, ankles, and gait of middle-aged women in Korea and the Maasai tribe. METHODS Foot length, calf circumferen...

The Austin procedure is primarily a transpositional V osteotomy of the head of the first metatarsal for the management of hallux valgus. The procedure was first reported in the podiatric literature and attributed to Dr. Austin by Miller and Croce. The procedure was presented initially by Dr. Dale Austin in his 1981 publication. The procedure as described is a horizontally directed V osteotomy p...

BACKGROUND In 3D gait analysis, the knee joint is usually described by the Eulerian way. It consists in breaking down the motion between the articulating bones of the knee into three rotations around three axes: flexion/extension, abduction/adduction and internal/external rotation. However, the definition of these axes is prone to error, such as the "cross-talk" effect, due to difficult positio...

Background and Aims The present study aims to investigate the effect of a neuromuscular training program on knee valgus angle, range motion (ROM) muscle strength hip ankle in male adolescent football players with dynamic (DKV). Valgus is one most common abnormalities that involved causing non-contact damage anterior cruciate ligament (ACL). Methods This quasi-experimental study. Participants we...
