Acupuncture around the greater tuberosity of the femur combined with acupuncture at Xuehai acupoint alleviates the postoperative pain of elderly patients with intertrochanteric fracture.

Objective: To determine the efficacy of acupuncture around the greater tuberosity of the femur (AGTF) combined with acupuncture at Xuehai acupoint for postoperative pain in elderly patients with intertrochanteric fracture.

Methods: A total of 97 elderly patients with intertrochanteric fracture treated by proximal femoral nail antirotation (PFNA) were enrolled and randomly assigned into an observation group (Obs group, n=48) and a control group (Con group, n=49). The Obs group was treated by aspirin and AGTF combined with acupuncture at Xuehai acupoint for analgesia, while the Con group was treated by aspirin alone for analgesia. Both groups were treated for 7 consecutive days. The two groups were compared in pain degree (visual analog scale (VAS) score) after operation and hip joint function (Harris score), daily living ability (modified Barthel index (MBI) score), bone metabolism-related indexes, and inflammatory factors before and after treatment.

Results: At 1-7 d after operation, both groups had gradually lower VAS scores, and at 5 and 7 d after operation, the Obs group had a lower VAS score than the Con group (both P<0.05). Additionally, at 2 months after operation, both groups had higher Harris scores and MBI scores, and the scores of the Obs group were both higher than those of the Con group (both P<0.05). At 7 d after operation, both groups showed a decrease in serum beta collagen degradation products (β-CTx) and an increase in procollagen type I amino-terminal propeptide (PINP) (both P<0.05), but the differences between the two groups in β-CTx and PINP were insignificant (P>0.05). Moreover, at 7 d after operation, both groups showed a decrease in C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α), and the two levels in the Obs group were lower than those in the Con group (both P<0.05).

Conclusion: For elderly patients with intertrochanteric fracture, AGTF combined with acupuncture at the Xuehai acupoint can more effectively relieve their postoperative pain and postoperative inflammation and more strongly promote their postoperative recovery of hip joint function.
