  • Treatment of benign bone lesions of proximal femur using dynamic hip screw and intralesional curettage via Watson-Jones approach

    ObjectiveTo explore the effectiveness of dynamic hip screw (DHS) and intralesional curettage via Watson-Jones approach in treatment of benign bone lesions of the proximal femur.MethodsBetween March 2012 and December 2016, 20 patients (21 lesions) with benign bone tumors or tumor like conditions of proximal femurs were treated with DHS and intralesional curettage via Watson-Jones approach. Their average age was 27.8 years (range, 11-51 years), including 13 males and 7 females. The pathological diagnosis were fibrous dysplasia in 11 cases, simple bone cyst in 2 cases, aneurysmal bone cyst in 2 cases, benign fibrous histocytoma in 2 cases, giant cell tumor in 2 cases, and chondroblastoma in 1 case, including 3 pathological fractures. According to the Enneking staging system, 18 patients were in stage S1, 3 patients with pathological fractures in stage S2. There was no varus deformity or valgus deformity. The operation time, intraoperative blood loss, and time of full weight-bearing were recorded. X-ray film and CT were used to observe the bone graft fusion and location of DHS. Complications were recorded. Visual analogue scale (VAS) and Musculoskeletal Tumor Society (MSTS) scoring were used to evaluate function of lower limbs.ResultsThe average operation time was 177.1 minutes (range, 110-265 minutes). The average intraoperative blood loss was 828.6 mL (range, 200-2 300 mL). There was superficial incision infection in 1 case, deep incision infection in 1 case, and hip discomfort in 1 case, respectively. All patients were followed up 6-63 months (mean, 27.4 months). The time of full weight-bearing was 2 days in 2 patients with giant cell tumor and 2 to 13 weeks with an average of 7.2 weeks in the other patients. At last follow-up, VAS and MSTS were 0.19±0.51 and 29.62±0.97 respectively, showing significant differences when compared with the values before operation (3.52±2.62 and 23.71±8.77) (t=5.565, P=0.000; t=–3.020, P=0.007 ). X-ray film showed the all bone grafts fusion with mean time of 8.2 months (range, 5-12 months). There was no pathological fracture of the femur, local tumor recurrence, chronic hip pain, dislocation, or femoral head necrosis during follow-up.ConclusionThe treatment of benign bone lesion of the proximal femur using DHS and intralesional curettage via Watson-Jones approach is a safe and effective method.

  • Treatment of proximal femoral benign lesions by proximal femoral nail anti-rotation combined with curettage and bone graft through the Watson-Jones approach

    ObjectiveTo evaluate the feasibility and effectiveness of proximal femoral nail anti-rotation (PFNA) combined with curettage and bone graft through Watson-Jones approach in the treatment of proximal femur benign tumors and tumor like lesions.MethodsThe clinical data of 38 patients with benign tumors and tumor like lesions in the proximal femur who were treated through the Watson-Jones approach with PFNA combined with curettage and bone graft between January 2008 and January 2015 were retrospective analysed. There were 24 males and 14 females with an average age of 28 years (range, 15-57 years). Pathological types included 20 cases of fibrous dysplasia, 7 cases of bone cyst, 5 cases of aneurysmal bone cyst, 3 cases of giant cell tumor of bone, 2 cases of enchondroma, and 1 case of non-ossifying fibroma. Before operation, hip pain occurred in 19 patients, pathological fracture occurred in 12 patients, limb shortening and coxa varus deformity was found in 4 patients, and 3 patients received surgery for the local recurrence. The operation time, intraoperative blood loss, and full-weight bearing time after operation were recorded. Patients were followed up to observe union of bone graft and the position of internal fixator on X-ray films and CT images. Visual analogue scale (VAS) score was used to evaluate the level of pain. The Musculoskeletal Tumor Society (MSTS93) score was used to evaluate lower limb function. Harris hip score was used to evaluate hip joint function.ResultsThe operation time was 130-280 minutes (mean, 182 minutes) and the intraoperative blood loss was 300-1 500 mL (mean, 764 mL). After operation, 3 cases of fat liquefaction of incision healed successfully by carefully dressing, and the rest incisions healed by first intention. All patients started partially weight-bearing exercise at 2-4 weeks after operation. The total weight-bearing time was 3-6 months (mean, 4.2 months). All the patients were followed up 24-108 months (median, 60 months). Imaging examination showed that the bone graft fused and the fusion time was 8-18 months (mean, 11.4 months). During the follow-up period, there was no complication such as pathological fracture, femoral head ischemic necrosis, hip joint dislocation, internal fixation loosening and fracture, and no tumor recurrence or distant metastasis occurred. At last follow-up, the VAS score, MSTS93 score, and Harris score were significantly improved when compared with preoperative ones (P<0.05).ConclusionThe treatment of proximal femoral benign lesions by PFNA combined with curettage and bone graft through the Watson-Jones approach is safe and effective, with advantages of better mechanical stability, less residual tumor, and less postoperative complications.
