4.P.10 CUSTOM MADE INDIVIDUAL ENDOPROSTHESIS REPLACEMENT OF DISTAL RADIUS AFTER TUMOR

Abstract

There are results of our first experience treatment 8 patients who underwent endoprosthetic reconstruction of distal radius after excision of malignant tumors. All patients were treated in Sytenko Institute from 2004 to 2008 and had about 5 years follow-up. There are 3 males and 5 females and the median age at diagnosis was 36 (17–55) years. The resection length measured a mean of 8cm and was measure by radiographs, CT and MRI. Each case was malignant Giant cell tumor. There were 5 cases of primary tumor and 3 cases of local tumor relapse. The patients have had chemotherapy, tumor excision and individual custommade endoprosthetic reconstruction. Unfortunately all patients had one-two surgeries before treatment in our Clinic. We used author’s individual custommade endoprosthetsis which was performed from titanium and ceramic spraying. CT-measurement scale was used for preoperative planning and manufacture this distal radius prosthesis.

One patient has had deep soft tissue infection and we were needed to remove prosthesis. One more patient had proximal radius fracture 4 month after surgery and we performed bone plate osteosynthesis. All patients (except one infection case) have satisfactory wrist range of motion and functional result of upper limb from 10 month to 5 years follow-up.

It is proved that surgical procedure of the tumors of distal radius is a useful and main method of the treatment above-stated localization. The individual custommade prosthesis have a good perspectives for upper limb salvage surgery and reconstruction this area, allowing to receive good oncological and functional results.
