CLEAR-CELL CHONDROSARCOMA OF THE DISTAL ULNA TREATED WITH WIDE RESECTION AND FASCIA LATA SUSPENSOPLASTY: A CASE REPORT

Introdução / Introdution

In front a case of either aggressive or malignant tumor of the distal ulna, wide resection with free margin is the procedure of choice, however when performed alone, this procedure can produce loss of motion, impingement and pain, being necessaire to perform stabilization procedures.

Objetivo / Purpose

We presented a case-report of a patient treated with wide ulna excision and stabilization by a fascia lata tendon strip

Material e Método / Material and Methods

A 35-year-old male patient suffered a pathologic fracture of the distal ulna being diagnosed, after open biopsy, clear-cell chondrosarcoma. To ensure free margin excision, we resected 11 cm of the distal ulna, as well as the distal radioulnar joint, extensor carpi ulnaris and the TFCC. After, we harvested a 2.5x15cm fascia lata tendon strip and performed and suspensoplasty of the proximal stump with the fascia lata strip and the flexor carpi ulnaris.

Resultados / Results

At the 18-month follow-up, the patient presents extremely satisfied with the procedure, he presents and excellent result in the Ferracini Score (16/18), his PRWE was of 22/100, his QuickDash was of 15.9. In terms of motion he has normal flexion-extension and prono-supination motion compared to the contralateral side and a decrease of 10 degrees in the radioulnar deviation compared to the contralateral side. His grip strength is of 24kg (81% compared to the contralateral side). He has no pain on neither the wrist nor the tight and no signs of recidive at this point

Discussão / Discussion

Conclusão / Conclusion

The management of tumors of the distal ulna is always individualized being the wide resection with or without stabilization the choice more usually performed. We showed that despite the big resection, the suspensoplasty with the fascia lata tendon is capable of providing and stable proximal stump and also maintaining a good grip strenght
