Outcome Of Paediatric Neck Of Femur Fractures Treated By Internal Fixation – A Retrospective Case Series

Abstract

Background: Neck of femur fracture in the paediatric population are rare injuries. Most commonly  caused by high velocity injury or fall from height. There is high incidence of long term complications. The aim of this study was to evaluate radiological and functional outcome of paediatric neck of femur fractures treated by internal fixation.

Materials & Methods: This is a retrospective study done in Sree Balaji Medical College & Hospital, Chennai, India from May 2014 to May 2019. Total of 10 patients, 6 males and 4 females who sustained aged 2-12 years underwent internal fixation and completed a minimum of one year followup. Patients were divided according to  Delbet classification. The final outcome was evaluated using Ratliff criteria.

Results: The mean age of the patients was 7.4 years(2-12). Average follow up was 2.1 years(1-4years). According to Delbet's classification there were 0 type I, 4 type II, 4 type III and 2 type IV fractures. Reduction was achieved by closed methods in 6 patients and open reuction was done in 4 patients. According to Ratliff's method 9 patients had satisfactory outcome (9 good) and 1 patient had poor outcome who developed AVN of femoral head.

Conclusion: Internal fixation of paediatric neck of femur fracutures provides satisfactory and predictable outcomes following closed or open reduction irrespective of type implant used. Anatomic reduction and early intervention is the key to avoid long term complications.
