The aim of this study was to compare the efficiency of non-operative and surgical procedures in the treatment of ruptured Achilles tendon in athletes (professional and amateur). ⋯ The percutaneous method was easier technically than the open method. Time spent in hospital was 14.5 times shorter with the percutaneous procedure compared with the open procedure (percutaneous procedure: range 0.5-2 days, mean 0.79±0.36; open procedure: range 10-24 days, mean 11.46±2.70; p<0.00). Return to sport activities was twice as fast with the percutaneous procedure compared with the open procedure. There were no postoperative infections or reruptured Achilles tendon in the group treated with the percutaneous procedure. One patient in the group treated with the open procedure had postoperative infection (4.2%). In the non-surgical (conservatively treated) group, there were three reruptures of the Achilles tendon within one year, and one patient developed adhesions that resulted in loss of function and had to undergo an operation. The percutaneous method is the best method of surgical treatment for Achilles tendon rupture.

Influence of obesity on surgical outcomes in type III paediatric supracondylar humeral fractures.
Obesity was associated with poor treatment outcome in paediatric supracondylar humeral fractures. It is controversial about the association is related to more severe fractures in obese children or obesity directly affects treatment. The purpose of this study was to evaluate the influence of obesity on surgical outcomes after control of fracture severity. ⋯ Obesity was associated with more postoperative varus deformation and pin-related complications after surgical fixation for type III supracondylar fracture. These findings underline the importance of stable fixation and close post-operative monitoring in obese children.

While there is conflicting evidence regarding the importance of anatomic reduction for tibial plateau fractures, there are currently no studies that analyse our ability to grade reduction based on fluoroscopic imaging. The purpose of this study was to determine the accuracy of fluoroscopy in judging tibial plateau articular reduction. ⋯ Using both AP and lateral views for 5mm displacement had the highest accuracy, specificity, and ICC. Outside of this scenario, agreement was poor to moderate and accuracy was low. Applying this clinically, direct visualization of the articular surface may be necessary to ensure malreduction less than 5mm.

The aim of this biomechanical study was to analyse the influence of plate and screw positioning on peri-implant failure in dual plate osteosynthesis. We hypothesized that screw positioning rather than plate configuration influences the risk of peri-implant fractures. ⋯ The results of this study suggest that placement of the most proximal screws rather than the configuration of the plates is critical regarding the predetermined risk of peri-implant failure in dual plate osteosynthesis of the distal humerus. Varying levels of the outermost screws of corresponding double plates seem to be crucial to avoid complications related to the osteosynthesis.

Comparative Study
Histological analysis of cross-sectional area of quadruple hamstring tendons and patellar ligament samples in relation to age and gender.
The middle of the patellar ligament and the quadruple hamstring tendons (gracilis and semitendinosus) are two types of graft predominantly used in anterior cruciate ligament (ACL) reconstruction. The aim of this study was to determine the morphometric characteristics of patellar ligament grafts and hamstring tendon grafts and to compare the results according to subject age and gender. ⋯ All samples obtained from male subjects had larger cross-sectional areas compared with the samples taken from females. Furthermore, samples obtained from subjects aged 60 years or under had larger cross-sectional areas than samples obtained from subjects aged at least 61 years for all types of graft.
