A 47-year-old woman was presented to the emergency department. The limb of the patient was shortened, and her hip was mildly flexed, adducted, and internally rotated. Initially, the patient was misdiagnosed as posterior hip dislocation. However, after careful history taking and radiologic evaluation, her final diagnosis was developmental dysplasia of hip, which was a sequelae of poliomyelitis.

INTRODUCTION The anterior dislocation of the hip represents only a small percentage of all hip dislocations: 85% are posterior. Most commonly associated with this dislocation is a fracture of the femoral head and, in rare cases, a femoral neck fracture. We have found in literature no report of an anterior dislocation of the hip associated with femoral neck fracture, pelvic retention of the head...

Developmental dysplasia of the hip refers to a continuum of abnormalities in the immature hip that can range from subtle dysplasia to dislocation. The identification of risk factors, including breech presentation and family history, should heighten a physician's suspicion of developmental dysplasia of the hip. Diagnosis is made by physical examination. Palpable hip instability, unequal leg leng...

A prerequisite for the development of congenital dislocation of the hip is ligamentous laxity of the hip-joint, which is demonstrable shortly after birth when the hip can be easily dislocated and reduced. This situation is described as dislocatable hip. Ligamentous laxity naturally tends to disappear, and 90% of all dislocatable hips in fact stabilize spontaneously. No dislocation develops unle...

The term "developmental dysplasia or dislocation of the hip" (DDH) refers to the complete spectrum of abnormalities involving the growing hip, with varied expression from dysplasia to subluxation to dislocation of the hip joint. Unlike the term "congenital dysplasia or dislocation of the hip," DDH is not restricted to congenital problems but also includes developmental problems of the hip. It i...

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...

As early as 1678 Pare stated that lame people beget lame children, and in 1882 KrUnlein compiled the family trees of many generations of children with congenital dislocation of the hip. In series of patients with congenital hip dislocation a hereditary factor was noted in 20 2 per cent by Isigkeit (1928), in 227 per cent by Scaglietti (1932) and in 6l per cent by Francillon (1937). Mercer (1950...

Despite the widespread introduction of neonatal screening programmes, the late presentation of congenital dislocation of the hip remains a considerable problem. Important gaps in our understanding of the natural history of this condition make it difficult to assess the effectiveness of screening. An audit of late presenting cases of congenital dislocation of the hip in south Bedfordshire betwee...

INTRODUCTION Recurrent dislocation of a total hip replacement prosthesis is a frustrating complication for both the surgeon and the patient. For positional dislocations with no indications for revision surgery, the current best treatment is physiotherapy, the use of abduction braces and avoidance of unsafe hip positions. Abduction braces can be cumbersome and have poor compliance. We report the...
