Functional and radiographic evaluation of the treatment of traumatic bone loss of the hand using the Masquelet technique

Abstract : This study was a retrospective evaluation of 18 patients with traumatic bone loss affecting the fingers, hand and wrist who were treated using the induced-membrane technique. Sixteen men and two women, mean age 54years (27-74) presented a hand injury including bone loss. Sixteen patients were treated on an emergency basis and two following nonunion of their fractures. There were 13 cases of open fracture of the phalanx and 5 cases of metacarpal fractures. These patients were treated with debridement and the injuries were covered when necessary. To address the bone loss, the first step of the induced-membrane technique involved placing a cement spacer (polymethylmethacrylate [PMMA]) without antibiotics in the defect. During the second step, the cement spacer was removed and replaced by autologous cancellous bone graft. The graft was placed within the biological tube left empty after removal of the cement. For each patient, bone union was assessed with radiographs and/or CT scan. Failure was defined as nonunion at 1year. In 16 patients, the fractures had healed after 4months (1.5-12months) on average. Two failures were noted (one nonunion treated using a PIP prosthesis and one case of delayed union). Mobility of the fingers, evaluated using the Total Active Motion (TAM) was 145° (75°-270°). The Kapandji score reached 8 for the thumb. Grip strength reached 21kg/F and pinch strength was 5kg/F; these values were 50% of those in the healthy hand. The induced-membrane technique is simple and can be used to treat traumatic bone loss in an emergency, thus avoiding amputation and limb shortening, while preserving limb function. It provides immediate stability and allows early mobilization.
