Traditionally, correction of femoral deformity has been performed with osteotomies through the center of rotation of angulation (CORA), but the CORA location is not always practical. If the osteotomy is created at a site adjacent to the CORA, an additional translation must be performed to accurately correct the deformity. However, at times, the ideal osteotomy site may require an unfeasible amo...

background: high tibia osteotomy (hto) is a common surgical operation for correction of genu varum deformity. in some patients,there are concurrent tibia vara and genu varum (bow leg). this study aimed to consider the possibility of better correction of bow leg deformity after double level tibial osteotomy (dlto). materials and methods: a case series of 10 patients of genu varum in addition to ...

skeletal deformities are a common problem in fish hatcheries and commercial farms that affect growth, development and survival as well as the market value of the final product. among the nutritional components, phosphorus (p) and calcium (ca) are of special interest as they are directly involved in the development and maintenance of the skeletal system. hence, the present study was carried out ...

the purpose of this study is to summarize the treatment options for scoliosis and spine deformities from antiquity through medieval times up to the renaissance. furthermore, it is to present the contribution of “the father of modern surgery”, ambroise paré (1510-1590), to this field. paré was a distinguished surgeon of the renaissance with many contributions to surgery, including war trauma, ob...

spine surgery began its evolution in the beginning of the 19th century in order to reach nowadays the point of being considered an important subspecialty of neurosurgery and orthopaedics. the purpose of this historical review is the search and evaluation of the progress in spine surgery in the second half of the 20th century. this review concerns the evolution of this field in greece. special r...

An opening-wedge osteotomy is well recognised for the management of limb deformity and requires an understanding of the principles of geometry. Translation at the osteotomy is needed when the osteotomy is performed away from the centre of rotation of angulation (CORA), but the amount of translation varies with the distance from the CORA. This translation enables proximal and distal axes on eith...

BACKGROUND Adolescent girls treated with a brace for scoliosis are submitted to prolonged stress related to both the disease and the therapy. Currently proposed quality of life questionnaires are focused on the outcome of therapy. Bad Sobernheim Stress Questionnaire (BSSQ) enables monitoring of patients being under treatment with a brace or exercises. The aim of the study was to assess the stre...

BACKGROUND Cam-type femoroacetabular deformity in acetabular dysplasia (AD) has not been well clarified. The primary purpose of this study was to determine the prevalence and characteristics of femoroacetabular deformity in symptomatic AD patients. METHODS We retrospectively reviewed the cases of 86 women (92 hips) and eight men (eight hips) with symptomatic AD. The mean patient age was 37.9 ...

OBJECTIVE Cam deformity and acetabular dysplasia have been recognized as relevant risk factors for hip osteoarthritis (OA) in a few prospective studies with limited sample sizes. To date, however, no evidence is available from prospective studies regarding whether the magnitude of these associations differs according to sex, body mass index (BMI), and age. METHODS Participants in the Rotterda...

The progression of post-tubercular kyphosis in 61 children who received ambulatory chemotherapy was studied prospectively. The angles of deformity and kyphosis were measured for each patient at diagnosis, 3, 6, 9, 12 and 18 months later and every year thereafter for 15 years. During the course of the disease signs of instability appeared on the radiographs of some of the children. These were di...
