Abstract:

BACKGROUND: Under new adjuvant chemotherapy and artificial false body design help, effects of body malignant bone cancer treatment can be greatly improved, and joint replacement becomes the main limb-salvage method for malignant bone cancer treatment.
OBJECTIVE: To observe curative effect of rotating hinged knee prosthesis on malignant bone tumors limb-salvage treatment.
METHODS: Totally 15 patients with knee malignant bone tumors were treated with prosthesis rotating hinged replacement from Department of Orthopedics, First People’s Hospital of Yancheng between January 2005 and October 2009. Postoperative Enneking musculoskeletal tumor by limb function after knee surgery reconstruction assessment standards were used for evaluation.
RESULTS AND CONCLUSION: Totally 15 patients were followed-up for 7-51 months. Postoperative complications were found in one patient, check results of erythrocyte sedimentation rate was increased, after debridement, joint solution and anti-inflammatory treatment, joint function was restored. Postoperative tumor recurrence, lung metastasis, prosthesis loosening and fracture were not appeared in all the patients. Enneking function evaluation, limb function excellent for seven cases (46.7%), good for five cases (33.3%), poor for three cases (20.0%), excellent and good rate was 80%. It is indicated that the effect of rotating hinged knee prosthesis replacement for knee malignant tumor is well, which can keep good limb function and is a kind of relatively satisfactory limb-salvage method.
