Data Trace Editor – Discussion: – most common error is non isometric anterior tunnel placement within intercondylar notch rather than at its normal posterior insertion; – ACL graft should pull up into tibial tunnel by about 2mm with extension when fixed on femoral side; – this represents the closest reconstitution of … Read more

Poor results of dynamization. – Femoral-shaft fractures and nonunions treated with intramedullary nails: The … Read more
– Discussion: – External Fixation – ref: External fixation of pediatric femoral fractures. – IM Nailing: (flexible vs rigid) – avascular necrosis is a reported complication in young adolescents; – consider IM entry point anterior to piriformis fossa; – children w/ coxa … Read more
– Discussion: – child abuse: 30% of femoral frx in children < 4 yrs are 2nd to child abuse; – Over-riding of Fracture Fragments: – in children between the ages of 2-10 yrs, overgrowth averages 0.9 cm; – in kids between 2 & 10 yrs, side to side apposition … Read more
– Discussion: – child abuse: child abuse occurs in 50-80% of children < 2 yrs w/ femoral frx; – limb length inequality are seldom a problem since frx does not shorten excessively; – acceptable reduction: – in children younger than 2 yrs, shortening of … Read more
– Measurement of Length: – its essential to plan ahead to achieve proper leg length; – w/ comminuted frx, use opposite leg to determine leg length; – one method is to obtain long cassette radiograph of opposite side w/ radiographic ruler included on the film; … Read more
– Discussion: – performed to correct either anteversion / valgus deformity of femoral neck in patients w/ dysplasia that reduces w/ abduction and medial rotation; – if hip is not reducible, then open reduction is performed prior to osteotomy; – the procedure is most useful when the acetabular dyspasia … Read more
– Discussion: – physeal bone bridges – methods to estimate growth potential – anatomy of distal femoral physis – distal femoral physis grows roughly at a rate of 9 mm/year (girls finish growing at age 14) – growth arrest, partial or complete, w/ progressive angulation &/or shortening ranges from 30% & 80% of pts; … Read more
– Discussion: – goal: ream close to endosteal cortex, which has strongest cancellous bone; – enter medullary canal w/ curet, & ensure that there are no perforations; – this is esp important w/ osteoporotic bone; – to enlarge medullary canal of diaphysis, use … Read more
