Low grade chondrosarcoma is currently followed up with the same schedule as all other chondrosarcoma patients. When treated adequately, low grade chondrosarcoma appears to have a very benign follow up course. A retrospective study of follow ups was done on fifty six patients treated for chondrosarcoma at the Pretoria musculoskeletal tumour unit from 1987–2009, evaluating the outcome and presence of local recurrence. The lesions were divided into four histological grades; atypical enchondroma (grade 0), low grade chondrosarcoma (grade 1), intermediate grade chondrosarcoma (grade 2), and high grade chondrosarcoma (grade3). Biopsy revealed forty-six patients with low grade chondrosarcoma (82%), nine cases of grade 2 chondrosarcoma (16%), and one patient with a metastatic mesenchymal chondrosarcoma. The femur and humerus were the commonest sites involved, while the axial skeleton was only affected in three cases, all of whom had more aggressive lesions. Forty-nine patients had no recurrence after a mean period of 57.5 months follow up. Forty- two of those had low grade lesions, and seven patients had grade 2 lesions. Two patients with low grade lesions were lost to follow up. Three patients involved in the study presented with local recurrence, but no metastases were detected radiographically. Two patients died, one with metastatic mesenchymal chondrosarcoma involving the scapula, and the other with a grade 2 lesion of the pelvis.Patients and Methods:
Results:
Operative treatment of Lisfranc joint injuries typically includes reduction and stabilization of the medial and middle columns of the midfoot. Mobility of the lateral column is preserved where possible, such that indications for lateral column stabilization rely upon the surgeons assessment of instability. In this case series, the indication for lateral column stabilization was defined by the results of an intra-operative stress test. The purpose of this study was to determine whether an intra-operative fluoroscopic stress test of the lateral column was sufficient to determine the need for internal fixation of the lateral column in Lisfranc joint injuries. 35 adult patients with Lisfranc injuries operated in our centre by a single surgeon from 2005–2009 were reviewed. All patients had unstable midfoot fracture dislocations, treated by reduction and internal fixation including an intra-operative stress examination to determine the need for lateral column fixation. Patients were contacted for clinical and radiographic review at a mean of 31 months post injury. Functional outcome was assessed using general and joint-specific outcome tools (AOFAS midfoot score and LEM). Radiographic review included analysis of joint displacement and arthritic changes in preoperative, postoperative, and most recent radiographs.Purpose
