Studies of congenital dislocation of the hip have ranged in their conclusions from the words of Hey Groves (1928) : “ Congenital dislocation of the hips is a deformity which is mysterious in its origin, insidious in its course and relentless in its final crippling results,’ ‘ to those of Brewster (1945) : “ The etiology of the congenital dislocated hip is unknown. Many theories have been advanc...

BACKGROUND Congenital dislocation of the knee (CDK) is a very rare condition that comprises a spectrum of deformities from subluxation to complete dislocation. The incidence of CDK is estimated at 1 per 100,000 live births, which is 1% of the incidence of developmental dysplasia of the hip (DDH). Moreover, 40-100% of patients with CDK have additional musculoskeletal anomalies, the most common b...

developmental dysplasia of the hip (ddh) and flatfoot are common pediatric orthopedic disorders, being referred to and managed by both general and pediatric orthopedic surgeons, through various modalities. our study aimed to evaluate their consensus and perspective disagreements in terms of diagnostic and therapeutic approaches of the mentioned deformities. forty participants in two groups of g...

Old neglected dislocation of knee joint is a rare injury. Any orthopaedic surgeon would have faced only a few cases of unreduced neglected dislocation in his life time practice. We report the case of a 30-year old male patient with one month old unreduced knee dislocation which was managed with open reduction and stabilization with two intra-articular crossed Steinman pins for six weeks, follow...

We carried out three total knee replacements with proximal realignment in two patients with severe osteoarthritis of the knee and congenital dislocation of the patella. During the operation, the femur and the tibia were cut according to the recommendations of the manufacturer of the implant. The femoral component was placed in external rotation and the centre of the tibial component aligned in ...

Dislocation after total knee arthroplasty is a difficult problem and is even more challenging if it occurs following revision. We report the case of a 82 year old male presenting after a frank posterior dislocation (Cam Jump) in a posterior stabilized revision knee arthroplasty without trauma. Flexion space instability with extensor insufficiency was presumed to be the cause of the dislocation ...

During an eight month prospective study, 8240 newborns were examined for detection of congenital dislocation of the hip from Oct. 23, 1991 to June 22, 1992. On fIrst examination we found 1302 neonates (158/1000 live births) to have abnormal hips 1063 (81.6%) were prone to subluxation (subluxatable), 218 (16.81 %) prone to dislocation (dislocatable), 17 (1.3%) were dislocated and 4 (0.3%) w...

The rotating hinge knee prosthesis is a popular intervention in patients lacking stability with highly constrained total knee arthroplasty. Despite improvements in design, nonmechanical and mechanical complications continue to be a problem. Dislocation of the hinge has been widely described, mainly due to the component fracture. Few reports describe isolated dislocation of the rotating stem. We...
