Dysplasia of the hip is characterized by malpositioning of the proximal femur in a shallow acetabulum, providing deficient femoral head coverage. This abnormal relationship leads to altered biomechanics of the hip joint, as predicted by measurement of kinematic parameters such as increased load over reduced acetabular weight-bearing area, leading to increased joint contact stresses, which subse...

AIMS We report a prospective cohort study of the midterm results of surgical dislocation of the hip (according to Ganz) to perform resection of osteochondromas involving the femoral neck in patients with multiple hereditary exostoses (MHE). METHODS Hip range of movement (ROM) was assessed pre- and post-operatively. Patients' judgment of post-operative reduction of pain, symptoms, the Rand 36-...

Retained intramedullary femoral nails can pose a problem for the implantation of the femoral component during total hip arthoplasty (THA) and they must often be removed. A patient with a retained Küntscher femoral nail implanted 47 years previously presented in our outpatient clinic for a THA. Since removal of the nail was impossible without severe damage to the femur, we chose to perform an ex...

Rotational deformity following intramedullary nailing may cause symptoms and require surgical correction by osteotomy. Reamed, locked intramedullary nailing may be performed, but concern about cortical blood supply and potential pulmonary dysfunction from reaming have led many surgeons to limit this and use smaller diameter nails. Slotted nails are commonly used but are less stiff in torsion th...
