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...

Background For the flat foot deformity, the custom made foot orthosis supported medial longitudinal arch using the navicular pad. And we experienced many cases that addition the metatarsal pad which supported transverse arch of the forefoot was more effective treatments. However, the flexibility of the transverse arch in the flat foot deformity was unclear. The aim of this study was to clarify ...

Spinal tuberculosis (Pott disease) can produce severe deformities when it is not properly treated. Long instrumentations through single or combined double approaches are usually required to prevent and correct the deformity. The authors present a case of severe deformity secondary to tuberculous spondylodiscitis in the lumbar spine treated with a monosegmental instrumentation through a double a...

The aim of this study was to estimate the burden of childhood rickets-like bone deformity in a rural region of West Africa where rickets has been reported in association with a low calcium intake. A population-based survey of children aged 0.5-17.9 years living in the province of West Kiang, The Gambia was conducted in 2007. 6221 children, 92% of those recorded in a recent census, were screened...

Bad Sobernheim Stress Questionnaire (BSSQ)-Deformity and BSSQ-Brace are the most widely used instruments for evaluating stress levels in adolescent idiopathic scoliosis (AIS) patients under brace treatment, and good reliability and validity have been demonstrated across different cultures. Great stress has been found among many adolescents, becoming a major concern for professionals. However, n...

The Synthes Spine Vertical Expandable Prosthetic Titanium Rib (VEPTR) allows new growth sparing surgical procedures for treatment of spine deformity in early childhood. The prime FDA indication for its use is the presence of thoracic insufficiency syndrome [1], which is the inability of the thorax to support normal respiration or lung growth. This syndrome is most often due to three-dimensional...
