Abstract
BACKGROUND: The distal end radius (DER) is the third most common site of a giant cell tumour (GCT) in bone. GCT is a locally aggressive benign tumour with metastatic potential. The main goals in the management of GCT of DER are the complete removal of the tumours, the prevention of recurrence, and the restoration of the functional wrist. PURPOSE: This case series reports the clinical and functional outcome of en bloc tumour resection, ulnar translocation and wrist arthrodesis in patients with high-grade GCT of DER. METHODS: Sixteen patients with Campanacci grade II & III GCT of distal end radius who underwent the procedure between 2009 and 2018 and had a follow-up of 2 years were included. Patients with distant metastasis, chronic severe systemic illness, operated previously, and follow-up dropouts were excluded from the study. The patient's demographic profile and tumour characteristics were collected at the initial visit. Grip strength, modified MAYO wrist score, and VAS score for wrist pain were collected preoperatively and at 1-year and 2-year follow-ups. RESULTS: The study included predominantly females (13 vs 3). The mean age was 31.5 ± 8 years with a symptom duration of 6.5 ± 3.1 months (range 3-14). The mean resection length was 8.31 ± 1.5 cm (range 6-12). The mean Ulnoradial and ulnocarpal union time was 22.7 ± 8.0 and 17.5 ± 2.3 weeks, respectively. The mean modified Mayo Wrist score was 20.63 ± 9.4, 48.7 ± 5.6 and 60.6 ± 4.0 at preop, 1 year and 2 years follow-up. The mean MSTS score was 22.68 ± 1.8 (range 19-26). Two patients had ulnoradial nonunion. CONCLUSION: Wrist arthrodesis by ulnar translocation and plate fixation is a viable option in the management of GCT of distal end radius. The short-term clinical and functional outcomes are favourable for restoring adequate wrist function.
