Aim: The purpose of this study was to evaluate the results of transphyseal ACL reconstruction technique in skeletally immature patients.

Material & Methods: Between 2002 and 2008, twenty knees in twenty skeletally immature patients with a mean chronological age of 13.2 years (range, 7 to 16.2 years) underwent transphyseal reconstruction of the anterior cruciate ligament with use of an autogenous quadrupled hamstrings-tendon graft with metaphyseal fixation. Ten knees had additional meniscal surgery. The functional outcome, graft survival, radiographic outcome, and any growth disturbance were evaluated at a mean of 2.2 years (range, 1.0 to 5.9 years) after the surgery.

Results: No patient underwent revision anterior cruciate ligament reconstruction. The mean International Knee Documentation Committee subjective knee score (SD) was 90.5 (10.0) points and the mean Lysholm knee score was 92.2 (10.0) points. The result of the Lachman examination was normal in 18 knees and nearly normal in two; it was not abnormal or severely abnormal in any knee. The mean increase in total height was 7.2 cm (range, 1.2 to 20.4 cm) from the time of surgery to the time of final follow-up. No angular deformities of the lower extremity were measured radiographically, and no lower-extremity length discrepancies were measured clinically. Complications included one case of knee stiffness requiring physiotherapy, one case of persistent pain leading to medial menisectomy for tear and one case of re-injury five months post ACL reconstruction requiring medial meniscus repair.

Conclusion: Excellent functional outcome was noted in skeletally immature patients after transphyseal reconstruction of the anterior cruciate ligament with use of an autogenous quadrupled hamstrings-tendon graft with metaphyseal fixation. There were very few complications and no growth disturbance.

Aim: The purpose of the study was to report the outcome of Flexible elastic nailing for femoral shaft fractures in children

Materials and Methods: Sixty-three femoral shaft fractures in 62 children treated with titanium flexible elastic nailing over a 10 year period (1998–2007). There were 44 boys and 18 girls aged 7.4 to 15.6 yrs (mean 11.2 yrs). Their body weight ranged from 22 to 64.80 kg (mean 40.99 kg). The right side was involved in 36 and the left in 27 children (including 1 bilateral fracture). The mechanism of injury varied from Road traffic accidents (RTA) in 42, Sports in 2 and Falls in 18 children. The proximal third shaft was involved in 3, middle third in 50 and distal third in 10 children. The fracture pattern varied from Transverse in 28, Oblique in 21, Spiral in 12 and Comminuted in 2 children.

Results: All fractures united with a mean union time of 15 weeks (range 6 to 30 weeks). The average follow-up was 72 weeks (range 52–104 weeks). Outcome assessment using the Titanium Elastic Nailing (TEN) Score showed 63% excellent, 32% satisfactory and 5% poor results. The minor complications varied from transient knee stiffness in 8 children, prominent nail ends in 7 children, extensor lag in 2 children, and acceptable facture angulation in 2 children. The major complications were fracture malunion, non-union, delayed union in 1 child each and re-fracture at different level in one child. The mean leg length discrepancy after union was 8mm (range 0–13 mm). There were no cases of infection. This method of treatment provided stable fixation, early mobilization and discharge.

Conclusion: We found that good surgical technique with attention to surgical details resulted in 95% excellent to satisfactory outcome.

Elastic stable Intramedullary nailing (ESIN) is a method of treating femoral fractures in older children.

The purpose of this study is to report our results over a 9 year period. Between 1998 and 2007, 62 children with femoral shaft fracture were managed at our institution with flexible titanium nailing. There were 44 boys and 18 girls with a mean age of 12.4 years (range 6 to 16 years). The mechanism of injury varied from RTA, falls and sports. The right side was involved in 41 and the left in 23. Two children had bilateral fractures. The fracture was in the proximal one third in 3, middle third in 51 and the distal third of the diaphysis in 8 children. The fracture pattern varied from transverse in 33, oblique in 15, spiral in 10 and comminuted in 4 patients. 11 children had associated injuries and 2 had mild osteogenesis imperfecta and another 3 sustained pathological fractures (fibrous dysplasia - 1 patient; simple bone cyst -1 patient; aneurismal bone cyst – 1 patient). The surgical procedure was retrograde except in one child with a mid third oblique fracture where this technique failed and hence an ante grade insertion was performed.

All fractures united at an average follow-up of 18 months (range 12–24 months). The mean union time was 3.8 months (range 1.2 to 7.2 months). All patients were followed until the implant was removed and the mean insertion to removal interval was 13 months (5 to 29 months). The complications noted in our series were knee discomfort with stiffness (8 patients), pain from prominent nails (2 patients), malunion (1 patient), delayed union (1 patient), peri-prosthetic fracture (1 patient). There were no cases of infection.

In conclusion, the results of our series showed that Elastic stable Intramedullary nailing gives satisfactory outcome in management of femoral shaft fractures in children.
