Minimally invasive plate osteosynthesis in XXXX : one-year results of a prospective multicenter study.

@entity1 @entity174 @entity6342 @entity3192 @entity5818 @entity2530
PURPOSE: The aim of this multicentric study was to evaluate results of minimally invasive plate osteosynthesis (MIPO) for @entity6342 in terms of postoperative shoulder function, radiological outcome and number of complications. METHODS: A consecutive series of 76 @entity1 with @entity6342 were treated with locking plate using a minimally invasive antero-lateral approach in two orthopaedic departments. Functional results with Constant score and radiographic evaluation were available for 74 @entity1 at one-year follow up. RESULTS: The @entity1 achieved a mean Constant score of 71 (range 28-100). Each functional result was evaluated also for both centres without significant differences. Significant statistical differences were only found for younger @entity1 with better results (p   <   0.05). Twenty @entity1 (27  %) developed complications. @entity5818 occurred in 16.2  % of cases for @entity3192 (6.7  %) and for too proximal plate positioning (9.5  %). Primary screws perforation (2.7  %), secondary perforation due to cut-out (1.4  %), @entity2530 ( @entity2530 ) of humeral head (1.4  %), partial resorption of greater tuberosity (2.7  %), secondary dislocation of the greater tuberosity (2.7  %) and stiffness (2.7  %) were the other complications observed. CONCLUSIONS: The MIPO technique for @entity6342 was safe and reproducible for most common patterns of @entity174 . Major complication rate was apparently low due to a soft tissue sparing, deltoid muscle and circumflex vessels, with easy access of the bar area to correct positioning of the plate.
