The aim of the study was to investigate factors relating to calcium and bone metabolism which might explain the low incidence of osteoporotic fracture among Africans. Adult bone mineral status, hip axis length and biochemical indices were investigated in 20 Caucasians (10 male, 10 female) and 19 Gambians (12 male, 7 female) living in the UK. Bone mineral content (BMC), bone mineral density (BMD...

AIM To review and study the effect of lengthening along the anatomical axis of long bones and its relation to the mechanical axis deviation. METHODS We try in this review to calculate and discuss the exact clinical impact of lengthening along the anatomical axis of the femur on affecting the limb alignment. Also we used a trigonometric formula to predict the change of the femoral distal anato...

Patients with complete paraplegia after spinal cord injury (SCI) are unable to stand or walk on their own. Standing exercise decreases the risk of decubitus ulcers, osteoporosis, and joint deformities in patients with SCI. Conventional gait training for complete paraplegia requires excessive upper limb usage for weight bearing and is difficult in cases of complete quadriplegia. The purpose of t...

OBJECTIVE The purpose of this work was to analyze the relationship between intensity and duration of physical activity and composite indices of femoral neck strength and bone-mineral content of the femoral neck, lumbar spine, and total body. METHODS Physical activity was assessed by accelerometry in 143 girls and 150 boys (mean age: 9.7 years). Measurement of bone-mineral content, femoral nec...

In 1909, several years before the famous `Organizer’ experiments of Spemann and Mangold, Ethel Browne demonstrated induction of a secondary axis in hydra by grafting a hypostome. Based on this and subsequent work, in the late sixties, Lewis Wolpert proposed the theory of morphogen gradients and positional information. We have studied secondary axis induction by hypostome and foot tissue using t...

Hip-to-ankle radiographs have been used to evaluate lower limb alignment before and after total knee arthroplasty. However, earlier studies have inappropriately used correlation to assess the reproducibility of the radiographs. We determined the reliability of the hip-to-ankle radiograph using the Bland-Altman analysis. Two consecutive hip-to-ankle radiographs were obtained in 52 patients (52 k...

INTRODUCTION A misdiagnose and inadequate treatment of neonatal septic arthritis of the hip has multiple sequelae and causes a severe disability. The aim of this study is evaluation of treatment of residual deformity after type IVA neonatal septic arthritis of the hip by Pelvic support osteotomy. CASE PRESENTATION A 11-year-old, white girl, was treated surgically by pelvic support osteotomy. ...

The experimental result of hypothesis test for hip roof model with = 3:0 is shown in gure 3,where the x axis represents the statistic used in the test and the y axis represents 10, where is the signicance level. Figure 3 shows the result of test mean and covari-ance simultaneously. sample density sample distribution null distribution function null density function Figure 3: Test mean and covari...

BACKGROUND Instability of the hip joint is a source of great discomfort to the patient due to pain, limp and leg-length discrepancy. Pelvic support osteotomy with Ilizarov hip reconstruction, along with its various modifications, has emerged as a standard treatment modality for this difficult problem. We present a series of patients with unstable hips treated with a modification of the monolate...
