title: [The results of curettage and bone cementing for enchondromas of the distal femur].
abstract: OBJECTIVE
  We evaluated patients who were treated with curettage and cementing for enchondromas localized in the distal femur.
  
  
  METHODS
  The study included 13 patients (7 females, 6 males; mean age 54 years; range 43 to 65 years) who underwent surgery for enchondromatosis in the distal femur. Enchondromas were detected incidentally in 10 patients; of these, complaints of pain appeared afterwards in seven patients. Surgery involved curettage and cement filling of the defects. Preoperative biopsies were obtained in seven patients. Clinical evaluations were made with a visual analog scale. The mean follow-up period was four years (range 1 to 5 years).
  
  
  RESULTS
  Radiographically, the size of the lesions ranged from 3 cm to 6 cm (mean 4.5 cm). Computed tomography showed cortical extension in five patients and erosion leading to narrowing in the posterior cortex in one patient. The mean pain score decreased from 3.63 (range 0 to 7) to 0.54 (range 0 to 3) postoperatively (p<0.05). Histopathological diagnoses of surgical specimens were enchondroma in 12 patients and grade 1 chondrosarcoma in one patient. Postoperatively, only one patient who had erosion and narrowing in the posterior cortex required cast immobilization for three weeks. None of the patients had recurrence, sarcomatous changes, or infection. No functional loss developed after surgical treatment.
  
  
  CONCLUSIONS
  Treatment of femoral enchondromas with curettage and cementing yields successful functional and radiologic results.
