A New Technique of Reconstruction of Metacarpal After Enblock Resection of The Metacarpal for Giant Cell Tumour of Bone

Giant cell tumour of hand bones is uncommon especially in metacarpals. Considering its more aggressive behavior and higher recurrence rate in metacarpals as compared to the other long bones, enblock resection of involved metacarpal is often required. Following resection of metacarpal, the available reconstruction techniques include metatarsal substitution, vascularized or non-vascularized fibular graft, iliac crest strut graft and endoprosthesis. We describe a new technique of metacarpal reconstruction using a metacarpal shaped spacer molded from PMMA bone cement with a partially incorporated screw inside it. The part of the screw not incorporated inside the cement spacer was used for trapezio-metacarpal arthrodesis. This new technique ensures good local control of disease, good hand function, maintains aesthetic appearance of hand and avoids graft donor site morbidities associated with other reconstruction options.
