Lengthening of the humerus is now an established technique. We compared the complications of humeral lengthening with those of femoral lengthening and investigated whether or not the callus formation in the humerus proceeds at a higher rate than that in the femur. A total of 24 humeral and 24 femoral lengthenings were performed on 12 patients with(More)
This study evaluated the effect of limb lengthening on longitudinal growth in patients with achondroplasia. Growth of the lower extremity was assessed retrospectively by serial radiographs in 35 skeletally immature patients with achondroplasia who underwent bilateral limb lengthening (Group 1), and in 12 skeletally immature patients with achondroplasia who(More)
BACKGROUND Use of the Ilizarov technique for limb lengthening in patients with achondroplasia is controversial, with a high risk of complications balancing cosmetic gains. Although several articles have described the complications of this procedure and satisfaction of patients after surgery, it remains unclear whether lengthening improves the quality of(More)
BACKGROUND AND PURPOSE Ilizarov's technique and intramedullary rodding have often been used individually in congenital pseudarthrosis of the tibia. In this series, we attempted to combine the advantages of both methods while minimizing the complications. METHODS We reviewed 15 cases of congenital pseudoarthrosis of the tibia (CPT) who were treated with a(More)
SUMMARY Convergent type radioulnar translocation is an extremely rare form of injury occurring in a growing child. We report a case of convergent radioulnar translocation along with a radial head fracture in a young child. Open reduction of the elbow and internal fixation of the radial head fragment helped in achieving concentric reduction and good(More)
BACKGROUND Femoral rotation on AP radiographs affects several parameters used to assess morphologic features of the proximal femur but its effect on femoroacetabular impingement parameters remains unknown. QUESTION/PURPOSES We therefore evaluated and characterized the potential effect of femoral rotation on (1) AP alpha angle, (2) lateral-center edge(More)
We applied a comprehensive set of clinical and radiological criteria for the diagnosis of hypochondroplasia (HCH) in 160 patients with short stature 58 of whom were diagnosed to have HCH. Taking into account the genotypic and phenotypic variations in HCH, we conducted a study with these 58 patients and tested them for mutations in the fibroblast growth(More)
BACKGROUND Multiple radiographic parameters used for diagnosis and quantification of morphologic pincer features have emerged, but the degree to which pelvic tilt or rotation affects conventional radiography and EOS(®) is unknown. QUESTION/PURPOSES We asked: (1) What is the reliability of EOS(®) and conventional radiography at increasing sizes of(More)
BACKGROUND AND PURPOSE Complications related to the fibula during distraction osteogenesis could cause malalignment. Most published studies have analyzed only migration of the fibula during lengthening, with few studies examining the effects of fibular complications. PATIENTS AND METHODS We retrospectively reviewed 120 segments (in 60 patients) between(More)
