BACKGROUND A common pathologic finding in the knee associated with congenital longitudinal deformity is aplasia of one or both cruciate ligaments. We performed a radiographic analysis to assess the changes in the femoral intercondylar notch and the tibial eminence in relation to the status of the cruciate ligaments. METHODS Thirty-four knees in thirty-one(More)
Congenital pseudarthrosis of the tibia is a rare disease with a variable history. The pseudarthrosis is usually not present at birth (and therefore is not truly congenital) but occurs during the first decade of life. Paget in 1891 was the first to describe a case. The etiology is unknown. Neurofibromatosis plays a role in approximately 50% of patients. In(More)
PURPOSE Circular external fixators have several advantages over other surgical options in the treatment of limb length discrepancy and axial deformity. The innovative Taylor Spatial Frame (TSF) combines a rigid hexapod fixation system with the support of a web-based software program, and thus offers the possibility of simultaneous corrections of(More)
BACKGROUND Osteonecrosis (ON) of the femoral head is one of the main complications associated with treatment of developmental dysplasia of the hips (DDH). The reported rates of ON vary widely between 6% and 48%, suggesting varying factors in these studies influence the rate. Several studies suggest open reduction combined with femoral shortening provides(More)
A multicenter study on fibrous dysplasia of bone (FD) was promoted by the European Pediatric Orthopaedic Society in 1999 in order to gain insight into the natural history of the disease and to evaluate current diagnostic and therapeutic approaches. We collected and reviewed clinical, radiographic, pathological, and molecular genetic data when possible, from(More)
The results of functional treatment using the Pavlik harness in congenital dislocation and congenital dysplasia of the hip in children aged less than 11 months were examined by an EPOS study group. This study was conducted on 3,611 hips in 2,636 patients for a period of 1-9 years after treatment. The reduction rate was 92% in grade Tonnis 2 and 3; the(More)
BACKGROUND The Ponseti method for treatment of idiopathic clubfeet involves the use of serial casts, percutaneous Achilles tenotomy in most cases, and bracing with an abduction orthosis to prevent relapse. Although Ponseti recommended evaluation of the infant clubfoot strictly by palpation, many orthopaedic surgeons still rely on radiographs for(More)
BACKGROUND Diagnosis and early treatment of developmental dysplasia of the hip (DDH) continue to be issues of discussion. In 1992, a nationwide general ultrasound screening program using Graf technique was introduced to detect DDH in Austria. We investigated the effects of this program on the rates of operative and conservative interventions and the(More)
This study was designed to analyze the different therapeutic methods used by European Paediatric Orthopaedic Society members from 13 countries for congenital pseudarthrosis of tibia. The treatment data of 340 patients who underwent 1287 procedures for this condition were analyzed. The essential findings were that the method of choice needed to approach the(More)
