Abstract
Indroduction: Cephalomedullary nailing (CMN) has become popular in treatment of extracapsular proximal femur fractures due to its mechanical advantages. This study aims to analyse the functional outcomes of the same and factors affecting it.
Material and Methods: 140 prospective cases of extracapsular proximal femur fractures were treated with CMN between October 2016 and October 2017 with a minimum follow-up period of 12 months. Patients were clinically assessed with range of motion, weight bearing status, Harris hip score (HHS) and Short form (SF)-36 score. Radiologically, fracture reduction, change in neck shaft angle (NSA) and neck length ratio in comparison to unaffected hip.
Results: 140 patients, 52 had excellent while 88 had good HHS. Patient in age group 20-40 had an average HHS of 87.79, 40-60 age group had an average HHS of 87.41, while patients in age group > 60 years had an average HHS of 87.63. Patients achieved average full weight bearing at 9.94 ± 2.76 weeks (p-value 0.578). Change in the neck shaft angle (NSA) was statistically significant in the immediate post-operative and at 1-year radiographs (p-value <0.001). Comparison of neck length ratio between affected and unaffected hip showed no statistical difference. There was no significant difference in function, range of motion and HHS in males (88.51 ± 2.72) compared with females (87.61 ± 2.98) (p-value 0.082). There was no significant association between occurrence of limp with change in NSA and neck length ratio (all p values >0.05). 6 complications occurred (1 peri-implant fracture, 2 surgical site infections and 3 cases of helical blade migration).
Conclusion: CMN gives excellent functional outcomes in all AO types A1, A2, A3 irrespective of age and sex with early mobilisation, full weight bearing and better functional range of movement. Limp occurred independant of change in NSA and neck length ratio.
