Titanium cable binding plate combined with proximal femoral nail antirotation for recurrent fractures after treatment of unstable intertrochanteric fractures / 中华创伤杂志

ABSTRACT

Objective:To investigate the clinical effect of titanium cable binding plate combined with lengthened proximal femoral nail antirotation (PFNA) for fixation of recurrent fracture after treatment of unstable intertrochanteric fractures.Methods:A retrospective case series study was conducted for analyzing the clinical data of 17 patients with recurrent fracture of unstable intertrochanteric fractures admitted to Southwest Hospital of Army Medical University from January 2010 to January 2018. There were 7 males and 10 females, aged from 65 to 94 years [(75.7±13.2)years]. The patients were treated using titanium cable binding plate combined with PFNA. Anti-osteoporosis therapy was applied as well. X-ray images were performed at postoperative 3 days, 3, 6 and 12 months. The healing and complications of the patients were recorded. The Harris hip score, visual analogue score (VAS), physical health score (PCS), mental health score (MCS) and 36-item short form health survey questionnaire (SF-36) were evaluated before operation and at postoperative 6 and 12 months.Results:All patients were followed up for 12-18 months [(15.3±2.8)months]. Bone healing was achieved in all patients, and the postoperative bone healing time was 3-6 months [(3.6±1.1)months]. One patient developed lumbosacral pressure sores and recovered after dressing change. Two patients developed drooping pneumonia, which was completely relieved after symptomatic treatment including nebulized inhalation of antibiotics and sputum aspiration. At postoperative 6 and 12 months, Harris hip score was (76.5±5.2)points and (85.5±5.7)points, significantly higher than (32.8±5.1)points before operation ( P<0.05); VAS was (3.3±0.5)points and (1.2±0.7)points, significantly lower than (8.5±0.7)points before operation ( P<0.05); PCS was (44.2±4.9)points and (56.9±5.8)points, significantly higher than (29.3±4.7)points before operation ( P<0.05); MCS was (47.9±6.8)points and (58.4±7.9)points, significantly higher than (39.7±5.9) points before operation ( P<0.05); SF-36 was (493.9±85.7)points and (603.4±76.8)points, significantly higher than (415.9±88.2)points before operation ( P<0.05). Conclusions:Titanium cable binding plate combined with lengthening PFNA can provide stability of fracture end, promote fracture healing, reduce complications, relieve pain and improve patients' quality of life for recurrence of unstable intertrochanteric fracture.
