Wide resection for giant-cell tumor of the distal radius: which reconstruction? A systematic review of the literature and pooled analysis of 176 cases

Abstract

Giant-cell tumor (GCT) is often more aggressive when located in the distal radius, and wide resection is then the gold-standard. No single reconstruction protocol is recommended, and the technique depends upon the surgeon's preferences. The aim of the present review was to determine the recurrence rate of GTC of the distal radius after intralesional treatment, to assess the results, advantages and complications of the various surgical techniques, and to draw up a decision-tree for surgical indications. The review of literature was performed in the main healthcare databases, searching for studies that reported results of wide resection and reconstruction of distal radius GCT. Local recurrence rates, metastasis rates, reconstruction techniques and respective results and complications were evaluated and analyzed. Sixteen studies were selected, for a total population of 226 patients; 6.0% and 0.9% experienced local recurrence and lung metastasis, respectively. Arthroplasty with non-vascularized or vascularized ipsilateral fibula were the most common techniques and were associated with the highest satisfaction rates: 86.4% and 88.0%, respectively. Arthroplasty with allograft presented a MusculoSkeletal Tumor Society (MSTS) score of 79.2% and arthroplasty with custom-made prosthesis presented an MSTS score of 81.8%. Arthrodesis was performed in 46 cases, with an MSTS score of 82.7%. Arthroplasty techniques are the most common in literature; they are used in patients who wish to conserve joint motion. Reconstruction with non-vascularized fibula seems to provide the best results, with lower morbidity. Arthrodesis is usually reserved for heavy manual workers or in case of arthroplasty failure.
