    Introduction: The objective of this biomechanical study was to compare the respective efficiency of plate-screw fixation and screw fixation in an experimental model of a Schatzker type 4 fracture. Hypothesis: screw fixation and plate fixation have a similar load to failure. Materials and methods: This study compares the stability of Schatzker type 4 medial tibial plateau fractures fixed with either 36.5mm cancellous bone screw with a 16mm threaded segment or with six-holed buttress T-plate-screw system. A Schatzker type 4 fracture was modeled on an artificial bone model. In a first group of 10 fracture models, following the anatomical reduction, fractures were stabilized with screws with washers. In the second group, of 10 fracture models, fractures were stabilized with T-plate. After fixation ascending axial compression was applied on bone models (Instron machine). Results: Load bearing capacity was 1397.6 +/- 194.4 N in the Group 1 and 2153.2 +/- 204.4 N in the Group 2. The difference between the two groups was statistically significant (p < 0.001). Discussion: According to this result, experimental load bearing of bone models indicate that plate-screw fixation system has a significantly higher stabilization capacity than fixation with three screws alone. Our hypothesis was not confirmed. In order to maintain anatomical repositioning, plate-screw system is a more stable fixation method than the screw in medial tibial plateau fractures Schatzker 4 Level of evidence: 1.

    Open repair of Bankart lesions using suture anchors in hard workers
    (2006) Cetik, Özgür; Uslu, Murad; Özsar, Barış K.; Eksioğlu, Fatih; Çetik, Gülten
    The surgical techniques applied to recurrent anterior dislocation of the shoulder, especially in hard working patients, must reconstruct a stable shoulder joint with a good range of motion, which will not redislocate, so the patients can return to their hardworking duties. The aim of this study was to evaluate the results of open Bankart repairs with suture anchors, in high-demand sportsmen and hard workers with recurrent anterior shoulder dislocation. Thirty shoulders of 29 patients were included in the study. All patients were active hard workers. A modified deltopectoral incision was used and Mitek GII Suture Anchors were implanted with 7-10 mm intervals into the bone-cartilage zone of the glenoid rim. Average follow-up time was 30 months (range, 22-38). Postoperative results were analysed according to the Rowe Scoring System. We obtained good and excellent results in 93.3% of cases. The open Bankart repair using suture anchors appeared in this study as a reliable technique for hard workers or physically high-demand patients. © 2006, Acta Orthopædica Belgica.
