VOL. 75-B, No. 2, MARCH 1993 (Fig. 1). The usual below-knee amputation would have left too short a stump. We therefore decided to amputate the bone, 6 cm below the knee, and turn up a section of the healthy distal tibia on a long posterior flap to lengthen the stump. We excised the middle two-thirds of the tibia, with the anterior and lateral compartments, and disarticulated the foot at the ank...

In this paper, a three-dimensional Boundary Element model of the proximal tibia of the human knee is described and stresses and displacements in the tibial plateau under static loading are computed. The geometry is generated via three-dimensional reconstruction of Computerized Tomographies and Magnetic Resonance Imaging. Various models of different lengths from the tibia plateau are calculated....

normal 0 false false false en-us x-none ar-sa unicameral bone cysts (ubcs) are benign, osteolytic lesions which are often asymptomatic and are commonly seen in the proximal of humerus and femur. the average age at diagnosis is 9-11 years and there is a male preponderance with a male-to-female ratio of approximately 2-2.5 to 1. we describe a case of 5-year-old girl who presented to orthopedic cl...

  Congenital dislocation of the knee (CDK) is a rare disorder. We report the case of a 7-year-old girl with bilateral knee stiffness, marked anterior bowing of both legs, and inability to walk without aid. Radiologic investigation revealed bilateral knee joint dislocation accompanied by severe anterior bowing of both tibia proximally and posterior bowing of both femur distally, demonstrating ...

Bone loss from the paralysed limbs after spinal cord injury (SCI) is well documented. Under physiological conditions, bones are adapted to forces which mainly emerge from muscle pull. After spinal cord injury (SCI), muscles can no longer contract voluntarily and are merely activated during spasms. Based on the Ashworth scale, previous research has suggested that these spasms may mitigate bone l...

The objective of the following study was to determine the incidence of tibial dyschondroplasia (TD) among 4 crosses (crosses A, B, C, and D) of male meat-type commercial broilers and its relationship to gait score at 6 wk of age. At 38 and 39 d of age, 360 birds were evaluated individually for gait score. Three male chickens/pen with good walking ability (gait score of 0 or 1) and 3 male chicke...
