This prospective study assessed the outcome of percutaneous cannulated screw fixation in 49 of 60 acute scaphoid fractures. The union rate was 100% (mean time for radiological union at 12 weeks). There were no early or mid-term complications and all achieved an excellent functional recovery.

Objective: Pediatric femoral neck fractures are uncommon injuries. Accurate early reduction and fixation is recommended to avoid serious long-term complications. The aim of this study was to analyze the clinical and radiological outcomes of 12 children with femoral neck fractures who were treated with closed reduction and cannulated screw fixation. Method: Between November 2015 and December 2019, 12 children (4 males,8 females) with an average age of 9.7 were operated by closed reduction and cannulated screw fixation for femoral neck fractures. We evaluated the medical records of all patients, including age, gender, injury mechanism, fracture type, initial displacement, postoperative reduction, follow-up roentgenograms and Ratliff’s scores. Results: The mean follow-up was 22.3 months (range 12–47 months). Six Delbett type 2, five Delbett type 3 and one Delbett type 4 fractures were operated with an avarage time to surgery of 12.5 (range: 1-75 hours). Satisfactory outcomes according to Ratliff’s criteria were obtained in 10 (%83.3) children. Coxa vara occurred in 2 cases. Any avascular necrosis was not seen during the follow-up period. Conclusion: Early closed reduction and cannulated screw fixation may be effective to avoid long-term complications in pediatric femoral neck fractures.
