EARLY OUTCOMES OF FLEXIBLE INTRAMEDULLARY NAILING IN PEDIATRIC SHAFT OF FEMUR FRACTURES

Objective: To study the early outcomes and complications of fixation of pediatric shaft of femur fractures using flexible intramedullary nail. Study Design: Prospective observational study. Place and Duration of Study: Orthopedic Department, Bahawal Victoria Hospital Bahawalpur, from Jan to Jun 2021. Methodology: Children between the ages of 5-11 years with shaft of femur fractures were included in the study. Fixation of fracture was done using elastic intramedullary nail. Final outcomes of fixation were observed using Flynn and Schwend Scoring System. Six-month follow-up was done in all cases. Data was analyzed using SPSS-20. Results: Total 70 cases having shaft of femur fracture were included in the study. Age range of cases was 5-11 years with mean age of 7.75 ± 1.66 years and mean weight of 24.44 ± 4.77 kilograms. Mean diameter of femur medullary canal was 7.48 ± 0.63 millimeters and mean diameter of flexible nail was 3.03 ± 0.26 millimeters. Mean post-operative period of radiological union of fracture was 8.57 ± 1.05 weeks. Per-operatively, fracture site was approached in 4 (5.7%) cases. Migration of nail was not seen in any case. Final outcomes according to Flynn and Shwend Score were excellent in 62 (88.5%), satisfactory in 7 (10%) and poor in 1 (1.4%) case. Conclusion: Fixation of shaft of femur fracture using flexible intramedullary nailing technique is safe and reliable with good outcomes among children between 5-11 years of age.

Radiographic and Clinical Assessment of Intramedullary Nail Fixation for the Treatment of Unstable Metacarpal Fractures

Background: The purpose of the article was to evaluate clinical and radiographic outcomes in a case series of unstable metacarpal fractures treated with flexible intramedullary nail (IMN) fixation. Methods: A total of 55 patients with unstable metacarpal fractures between 2003 and 2010 were treated with IMN fixation and followed for a minimum of 1 year. The outcomes were assessed via a radiological study of longitudinal and angular collapse, Disabilities of the Arm, Shoulder, and Hand (DASH) score, total active range of motion (ROM) of the wrist, and grip strength testing. Results: In the 55 patients, metacarpal fractures were healed by clinical and radiographic assessment at an average of 12.7 weeks. IMNs were removed in all cases at an average of 13.9 weeks. Patients regained full finger ROM at the final follow-up and were capable of 72.4% of motion at 2 weeks postoperatively. The mean DASH score at the final follow-up was 6.5. Complications included 3 cases of extensor tendon irritation that resolved without functional impairment and 2 cases of “backing out” that required reoperation to replace the pin. In one case, a bony exostosis formed on the affected metacarpal that led to tendon irritation and required operative excision. Conclusions: We found that this technique allowed for the stabilization of fractures, early ROM, resumption of usual activities, reduced immobilization, and minimal complications. A removable orthosis, instead of a cast, allowed for earlier mobilization of the wrist, metacarpophalangeal, and proximal interphalangeal joints.
