Limb lengthening by callus distraction (callotasis).

Abstract: Callotasis is a new technique of limb lengthening involving slow distraction of the callus formed in response to a proximal submetaphyseal corticotomy. Using a dynamic axial fixator with telescoping capabilities, distraction begins after 2 weeks. When the required length is attained, the fixator is held in the rigid mode until radiographic evidence of callus is observed. The locking screw is then released, and dynamic axial loading is instituted to promote corticalization. One hundred bony segments have been lengthened; 50 patients had limb length inequality, and 23 had achondroplasia. The mean lengthening achieved was 22% (maximum, 58%). There were 14 complications (14%).

The POSNA pediatric musculoskeletal functional health questionnaire: report on reliability, validity, and sensitivity to change. Pediatric Outcomes Instrument Development Group. Pediatric Orthopaedic Society of North America.

Abstract: The goal of orthopaedic interventions is to improve the functional health of patients, particularly physical function. The American Academy of Orthopaedic Surgeons and the Pediatric Orthopaedic Society of North America (POSNA) commissioned a work group to construct functional health outcomes scales for children and adolescents, focusing on musculoskeletal health. The work group developed scales assessing upper extremity function, transfers and mobility, physical function and sports, comfort (pain free), happiness and satisfaction, and expectations for treatment. Parent and adolescent self-report forms were developed and tested on 470 subjects aged 2-18 years. The POSNA scales demonstrated good reliability, construct validity, sensitivity to change over a 9-month period, and ability to outperform a standard instrument, the Child Health Questionnaire physical functioning scale. They were useful for a wide variety of ages and diagnoses. They appear to be ideally suited for orthopaedic surgeons to assess the functional health and efficacy of treatment of their patients at baseline and follow-up.

Titanium elastic nails for pediatric femur fractures: a multicenter study of early results with analysis of complications.

Abstract: Titanium elastic nailing is used instead of traction and casting in many European centers, but limited availability has prevented widespread use in North America. Before a planned general release in America, titanium elastic nails (TENs) were trialed at several major pediatric trauma centers. This multicenter study is a critical analysis of early results and complications of the initial experience. Overall, TENs allowed rapid mobilization with few complications. The results were excellent or satisfactory in 57 of the 58 cases. No child lost rotational alignment in the postoperative period. Irritation of the soft tissue near the knee by the nail tip occurred in four patients, leading to a deeper infection in two cases. As indications, implantation technique, and aftercare are refined, TENs may prove to be the ideal implant to stabilize many pediatric femur fractures, avoiding the prolonged immobilization and complications of traction and spica casting.

Management and complications of anterior cruciate ligament injuries in skeletally immature patients: survey of the Herodicus Society and The ACL Study Group.

Abstract: Expert opinion regarding experience with the management and complications of pediatric anterior cruciate ligament (ACL) injuries was studied by surveying members of The Herodicus Society and The ACL Study Group. There was large practice variation in initial management and ACL reconstruction technique. There were 15 reported cases of growth disturbance: 8 cases of distal femoral valgus deformity with arrest of the lateral distal femoral physis, 3 cases of tibial recurvatum with arrest of the tibial tubercle apophysis, 2 cases of genu valgum without arrest, and 2 cases of leg length discrepancy. Associated factors included fixation hardware across the lateral distal femoral physis in 3 cases, bone plugs of a patellar tendon graft across the distal femoral physis in 3 cases, large (12 mm) tunnels in 2 cases, fixation hardware across the tibial tubercle apophysis in 3 cases, lateral extra-articular tenodesis in 2 cases, and over-the-top femoral position in 1 case. Based on this experience, we recommend a guarded approach to ACL reconstruction in the skeletally immature patient with careful attention to technique and follow-up.
