title: [Surgical treatment for proximal humerus fracture].
abstract: OBJECTIVE
  The aim of the study was to compare the medical aspects of alternative surgical methods for treatment of proximal humerus fractures in specific indications (two- and three- fragment fractures).
  
  
  METHODS
  A prospective randomised study on surgical treatment of two- and three-fragment fractures of the proximal humerus was carried out at the Department of Surgery, University Hospital in Hradec Králové, from January 2006 till January 2010. The study comprised patients with proximal humerus fractures indicated for surgical treatment. Study inclusion criteria were as follows: informed consent, AO fracture types A2, A3, B1 or C1, age between 18 and 80 years, and patient compliance. Exclusion criteria included open fracture, associated injury (AIS . 2), open growth plates, or such state of the patient's health that would limit the extent of surgery. Two groups were compared. One included patients treated by the Zifko method of minimally invasive osteosynthesis with intramedullary K-wire insertion (MIO group) and the other (ORIF group) consisted of patients undergoing open reduction with angle-stable osteosynthesis using a Philos plate (Synthes, Switzerland). The patients were randomised to the groups by a computer programme which facilitates the maintenance of homogeneity of the groups compared. The procedure in each patient was based on the sealed-envelope method.
  
  
  RESULTS
  The ORIF group comprised 28 patients. It took them an average of 27.2 weeks (9-72) to regain normal upper limb function. The final CM score was 86.6% (64-100%) as compared with the healthy limb. Excellent and good results were achieved in 89% of the patients; complications were recorded in 39% of them. The MIO group included 27 patients. The fractures healed in all of them. Normal upper limb function was regained at an average of 21.4 weeks (13-36). The final CM score was 87.5% (52-100%) in comparison with the healthy limb. Excellent and good results were achieved in 89% and complications developed in 33% of the patients.
  
  
  CONCLUSIONS
  The statistical evaluation of the results, using the unpaired t-test, did not show any significant differences either in functional outcomes or the number of complications between the two groups. The only significant difference was found in operative times (117 min and 72 min in ORIF and MIO groups, respectively). The difference in time needed to regain limb function (27 and 21 weeks) was at a marginal level of statistical significance. With both methods 89% of excellent and good results were achieved, and a similar number of patients had complications (11 and 9).
