T. Nakai et al., Therapeutic effect of transtrochanteric rotational osteotomy and hip arthroplasty on quality of life of patients with osteonecrosis, ARCH ORTHOP, 120(5-6), 2000, pp. 252-254
The reviewed 37 patients with avascular necrosis of the femoral head (ANF).
There: were 23 men and 14 women with a mean age of 36 years at the time of
the operation. The duration of follow-up was 9 years. Twenty patients had
undergone transtrochanteric rotational osteotomy (TRO) and 17, hip arthropl
asties. Assessment of their quality of life (QoL) was performed using the R
osser Index Matrix for disability and distress. Concerning TRO, the mean pr
eoperative and postoperative QoL scores were 0.944 and 0.957, respectively.
Twelve patients exhibited increases and 7 patients decreases in their scor
es. Regarding the arthroplasty the mean preoperative and postoperative QoL
scores were 0.949 and 0.998, respectively. All patients showed increases in
QoL scores after arthroplastic surgery. Concerning heavy manual work, all
five of those patients returned to their preoperative occupations. These fi
ndings suggest that hip arthroplasty has more reliable therapeutic effects
than TRO on QoL improvement for patients with ANF.
