Abstract:
Objective:To investigate the efficacy of cementless long-stem total hip arthroplasty (THA) in the treatment of end-stage osteonecrosis of the femoral head (ONFH) combined with ipsilateral subtrochanteric femoral fractures.Methods:A retrospective case series study was conducted on 18 patients with end-stage ONFH combined with ipsilateral subtrochanteric fractures who were admitted to the 940th Hospital of the Joint Logistics Support Force of the PLA from January 2016 to June 2023, including 8 males (8 hips) and 10 females (10 hips), aged 56-79 years [(69.4±7.0)years]. All the patients had Association Research Circulation Osseous (ARCO) stage IV ONFH combined with ipsilateral subtrochanteric fracture (Seinsheimer types II-IV). Parameters recorded included operation duration, intraoperative blood loss, length of hospital stay, time to partial weight-bearing, and time to full weight-bearing. Vertical offset and leg length discrepancy (LLD) were compared preoperatively and at 1 week postoperatively. Visual analogue scale (VAS) score, hip range of motion (flexion, abduction), and Harris hip score (HHS) were compared preoperatively, at 1 week, 3 months postoperatively, and at the last follow-up. Perioperative complications were observed.Results:All the patients were followed up for 12-70 months [(36.4±16.2)months]. Operation duration was (116.4±18.1)minutes. Intraoperative blood loss was (334.4±121.3)ml. The length of hospital stay was 13.0(10.0, 16.3)days. The time to partial weight-bearing was 5.0(3.0, 7.0)days, with time to full weight-bearing for 5.0(4.0, 5.3)weeks. At 1 week postoperatively, the vertical offset [(58.9±4.1)mm] was significantly increased compared to that preoperatively [(49.3±3.3)mm] ( P<0.01), while the LLD [(4.2±3.1)mm] was significantly reduced compared to that preoperatively [(16.2±5.8)mm] ( P<0.01). At 1 week, 3 months postoperatively and at the last follow-up, the VAS scores [3.0(2.0, 3.3)points, 2.0(1.0, 2.0)points, and 1.0(0.0, 2.0)points] were significantly lower than that preoperatively [6.0(5.0, 6.3)points], and decreased with the passage of follow-up time ( P<0.01); the hip flexion angles [(50.4±6.5)°, (94.3±6.4)°, and (104.7±7.4)°] and hip abduction angles [(21.5±4.4)°, (34.9±4.5)°, and (42.9±4.9)°] were lower than those preoperatively [(32.9±6.4)° and (13.4±4.9)°], and decreased with the passage of follow-up time ( P<0.01); the HHS [(58.1±4.9)points, (83.1±2.9)points, and (90.7±2.6)points] were higher than that preoperatively [(33.4±4.4)points], and increased with the passage of follow-up time ( P<0.01). At the last follow-up, 5 patients were rated as excellent, 11 as good, and 2 as fair according to the HHS criteria, with an overall excellent and good rate of 89%. No perioperative complications were observed, including neurovascular injury, secondary fracture, or infection. One patient developed partial deep vein thrombosis of the lower extremity (the popliteal vein) at 2 weeks after surgery, which recovered completely following treatment with a standard oral administration of rivaroxaban, etc. At the last follow-up, no evidence of malunion, prosthesis loosening, subsidence, or dislocation was observed. Conclusion:The use of cementless long-stem THA in the treatment of end-stage ONFH combined with ipsilateral subtrochanteric fractures has advantages of small trauma, early weight-bearing, early pain relief, improved joint motion and function, and few complications.
