Surgical treatment of clavicle displaced midshaft fractures with pre-contoured plates using mini invasive technique (MIPO)

Abstract

IntroductionThe midsahft clavicular fractures represent up to 10% of  skeleton fractures. Conservative treatment usually provides good results with low incidence of complications. However, surgical treatment should be considered in displaced, multifragmentary or significant deformity. The purpose of this retrospective case series is to present our experience in the treatment of closed and displaced midshaft clavicular fractures with pre-contoured plates with MIPO technique, description of the technical and preliminary functional results.Materials and MethodsA retrospective series of 13 patients (11 males  [84.6%] and 2 females [15.4%]), mean age of 31 years with closed and displaced midshaft clavicular fractures classified 2 B type according Robinson (Edinburgh) treated by reduction and internal fixation with pre-contoured plates osteosynthesis with mini-invasive technique (MIPO) between April 2010 and November 2013.  Mean follow-up of 13 months (range 11-25). Radiographic and CT controls are carried out, assessing the functionality using scales Constant - Murley modified DASH Quick and pain with visual analog scale (VAS).ResultsThe average time to surgery was 8 days, 35 minutes operating time 35 minutes and 1.28 postoperative days in hospital. The clinical and radiological consolidation was recorded at 15.2 weeks on average. The score average of Constant - Murley modified scale was 88 points, Quick DASH 26.9 and VAS 0.3. No systemic or cosmetic complications were recorded.ConclusionIn this series, mini-invasive osteosynthesis (MIPO) in displaced and closed midshaft clavicular fractures represented a reproducible technique with reduced surgical time and acceptable functional scores.
