Complex multi-fragment metacarpal fractures with cortical splits or intra-articular extension present a great challenge for optimal stable fixation that allows early post-operative mobilization. We describe a series of twelve metacarpal fractures requiring the use of cerclage wires as a salvage supplementary adjunct to internal fixation. Patients’ demographics, co-morbidities, surgical details, and outcomes were recorded. Three patients sustained the fracture on the non-dominant hand. Four fractures involved the head and neck of the metacarpals while the remaining fractures involved only the shaft of metacarpal. Three patients had comminution of the metacarpal fracture sustained from the initial intra-operative fixation, while two patients were revision surgery of previously failed fracture fixation. Internal fixation was performed with 1.7mm, 2.0mm, or 2.3mm metalware from the Stryker handset, depending on the patient’s bone quality. 24G, 26G, or 28G cerclage wires was then used as an adjunct to achieve additional stability and compression of the smaller fracture fragments. All fixations were deemed sufficiently stable for immediate post-operative early active mobilization. Patients were followed up in the Plastic Surgery clinic and assessed by hand therapists for post-operative range of motion. Three patients subsequently require removal of metalware between eight to fourteen months post-operatively. Cerclage wiring can be a useful salvage adjunct maneuver for internal fixation to achieve stable fixation in managing complex metacarpal fractures.
