We analysed LCP efficiency in type B and type C wrist fractures (according to the AO Classification). We treated 58 wrist fractures (19 B-type fractures and 39 C-type fractures) in 35 male and 23 female patients, aged 19 to 87 years. Forty-one cases were followed up for an average period of 13 months. We performed a volar approach on 32 patients, a dorsal approach on five, and a double approach on four (both volar and dorsal). Twenty-six cases were pre-operatively examined with CT. All patients were evaluated using the "Mayo modified wrist score", with an excellent/good result in 76% of patients and a satisfactory/poor result in 24%. The LCP system proved to be adequately reliable and stable to keep the reduction in complex fractures (e.g. the C-type fractures in patients with low bone quality).
