Our purpose was to report the use of an interlocking nail-hybrid external fixator construct to correct distal femoral deformities in three dogs. Radiographs, computed tomography and a three-dimensional model were used to plan the surgical procedure. A femoral osteotomy or ostectomy was performed at the level of the centre of rotation of angulation in all three dogs. Angular and rotational defor...

BACKGROUND Previous studies have suggested that compensatory valgus deformity of the femur is common in patients with tibia vara, or Blount disease. The availability and routine use of standing long-cassette radiographs of the lower extremities to assess angular deformities has allowed quantitative evaluation of this hypothesis. METHODS The cases of all patients with tibia vara, two years of ...

Six pairs of human cadaver femora were divided equally into two groups one of which received a non-cemented reference implant and the other a very short non-dependent experimental implant. Thirteen strain-gauge rosettes were attached to the external surface of each specimen and, during application of combined axial and torsional loads to the femoral head, the strains in both groups were measure...

The objective of this study was to evaluate the torsion stiffness of locked and unlocked distal fixation of long cephalomedullary nail constructs, in both a fresh fracture and healed, stable intertrochanteric fracture model. Samples were tested in both internal and external rotation (0±3 Nm) for a duration of 10 cycles. Each femur was tested without instrumentation (intact femur), with instrume...

The forces exerted by the soft and hard tissues of the thigh together represent a system in equilibrium. This balance of loads must be considered when the system components are examined independently. However, in many biomechanical analyses of the thigh, the femur is studied without considering soft tissue loading. To improve the understanding of femoral loading a three-dimensional model was de...

Chronic osteomyelitis involving the distal femur often results in amputation or arthrodesis. This article presents three cases of chronic osteomyelitis treated with a staged approach culminating in endoprosthetic reconstruction. Stage one involved resection of infected bone and placement of an intramedullary nail spanning the bony defect between proximal femur and tibia, with antibiotic cement ...

Giant cell tumour of bone (GCTB) is a rare benign tumour noted before physeal closure. GCTB cases in patients younger than 10 years are especially uncommon. The authors report the case of a 9-year-old girl with a GCTB of the distal femur. After initial intralesional excision and curettage of the tumour, local recurrence occurred, which needed two more additional surgeries to treat. The primary ...

Surgical reconstruction of the anterior cruciate ligamentdeficient knee has become very common, with the majority of reconstructions performed using the semitendinosusgracilis tendon autograft construct or the central third bonepatellar tendon-bone autograft construct. Although generally uncommon, complications after anterior cruciate ligament reconstruction occur, and may include fractures of ...

A fitly-one year old man reported to the outpatients department, Liaquat National Hospital, with a painful nodule on the distal end of the femur. The slowly growing nodule had grown to roughly 2 ems, in the last decade. The plain film radiographs showed a well-defined lytic lesion diagnosed as osteoid osteoma. The radiograph of the femur also showed a radiolucent mass with lobulated margins and...

Primary osteosarcoma of the bone with rhabdoid features is a rare malignant tumor of bone, not previously described in the literature. Here we report a 69-year-old female who originally presented with a right femur pathologic fracture. Radiographs of the injury showed an aggressive-appearing lesion of the distal femur. Initial biopsy was done, which was not diagnostic; additional advanced imagi...
