What the study found
The study describes a combined bone and ligament reconstruction approach after distal radius resection and reports that it was technically feasible. In the presented case, this strategy used a proximal fibular autograft and distal oblique bundle reconstruction to address both bone loss and distal radioulnar joint stability.
What the authors say this matters
The authors state that distal radius reconstruction is challenging because stability of the distal radioulnar joint and forearm rotation must be preserved. They conclude that their approach may allow preservation of distal forearm mechanics while maintaining oncologic principles.
What the researchers tested
This technical note presents a representative clinical case of Campanacci grade III giant cell tumor of the distal radius treated with segmental en bloc resection. Reconstruction used an ipsilateral, nonvascularized proximal fibular autograft including the fibular head, plus distal oblique bundle reconstruction with an autologous palmaris longus tendon graft. Functional follow-up used the Musculoskeletal Tumor Society scoring system and range-of-motion measurements.
What worked and what didn't
Histopathological examination confirmed negative oncologic margins. Early postoperative events included donor-site common peroneal nerve dysfunction and radiocarpal instability that required temporary Kirschner wire stabilization. At nine months, the Musculoskeletal Tumor Society score was 80%, with forearm rotation preserved at 68.8% pronation and 81.3% supination of normal values.
What to keep in mind
This report is based on a single representative case, so broader validation is still needed. The abstract also notes that larger clinical series and longer follow-up will be required. No additional limitations are described in the available summary.
