Musculoskeletal function and quality of life after an unstable trochanteric fracture treated with the trochanteric gamma nail.
OBJECTIVE
The aim of the study was to report the musculoskeletal function and health-related quality of life (HRQoL) after an unstable trochanteric fracture treated with a cephalomedullary nail.


METHODS
One hundred and seventeen patients, mean age 84.1 years, were included in a 1-year prospective cohort study. Outcome measurements included musculoskeletal function according to the Short Musculoskeletal Function Assessment (SMFA) and HRQoL according to the EQ-5D.


RESULTS
Fourteen patients (12.0 %) were reoperated on, all but one being due to a secondary lag-screw penetration/cut-out. The need for revision surgery was significantly higher after a 4-part fracture according to the Jensen-Michaelsen classification as compared to after a 3-part fracture, i.e. 17 versus 6 % (p = 0.048). The reoperation was a hip replacement in 12 of the 14 patients, a total hip replacement (THR) in 10 and a hemiarthroplasty in 2. The SMFA dysfunction and bother indices in all patients showed a significant deterioration at 12 months compared to before the fracture, from 24.8 to 42.4 (p < 0.001) and 14.3 to 33.7 (p < 0.001), respectively. The EQ-5D(index) score decreased from 0.79 prefracture to 0.51 (p < 0.001). The final outcome for the patients who underwent reoperation with THR was surprisingly good with an SMFA dysfunction index of 43.4, a bother index of 36.6 and an EQ-5D(index) score of 0.58.


CONCLUSIONS
An unstable trochanteric fracture treated with a cephalomedullary nail had a substantial negative impact on the patient's musculoskeletal function and HRQoL. The need for revision surgery was significantly higher after a 4-part fracture compared to after a 3-part fracture. The by far most common fracture complication, i.e. a secondary lag-screw penetration/cut-out, was successfully treated with a THR.
