Randomized Controlled Trial Comparative StudyA comparison of orthopaedic resident performance on surgical fixation of an ulnar fracture using virtual reality and synthetic models.
Surgical trainees develop surgical skills using various techniques, with simulators providing a safe learning environment. Fracture fixation is the most common procedure in orthopaedic surgery, and residents may benefit from simulated fracture fixation. The performance of residents on a virtual simulator that allows them to practice the surgical fixation of fractures by providing a sense of touch (haptics) has not yet been compared with their performance using other methods of practicing fracture fixation, such as a Sawbones simulator model. The purpose of this study was to assess whether residents performed similarly on a newly developed virtual simulator compared with a Sawbones simulator fracture fixation model. ⋯ The newly developed virtual ulnar surgical fixation simulator, which incorporates haptics, shows promise for helping surgical trainees learn and practice basic skills, but it did not attain the same standards as the current standard Sawbones simulator. The procedural measures used to assess resident performance demonstrated good reliability and validity, and both the Sawbones and the virtual simulator showed evidence of construct validity.

Randomized Controlled Trial
[Case-control studies on therapeutic effects of combined methods of minimally invasive percutaneous proximal humerus locked osteosynthesis plate with injectable bone for the treatment of proximal humerus fractures in elderly patients].
To evaluate the clinical effects of combined methods of minimally invasive percutaneous proximal humeral internal locking system (PHILOS) and injectable bone for the treatment of proximal humerus fractures in elderly patients. ⋯ PHILOS combined with injectable bone for the treatment of proximal humerus fractures in elderly patients has advantages of minimal wound, stable fixation, and earlier rehabilitation.

Randomized Controlled Trial Comparative Study
[Comparative study on effect and safty of treating on calcaneus fractures with manipulative reduction with percutaneous K-wire fixation].
To explore the clinical effects and safty of manipulative reduction with percutaneous poking K-wire fixation for the treatment of the calcaneus fractures and analyze the indication of the minimal invasion. ⋯ For tongue form or compressing form of Sanders type II and tongue form of Sanders type III, manipulative reduction with percutaneous poking K-wire fixation has advantages of minimal invasion, minimized complications. Compressing form of Sanders type III fracture should be treated with operative redution.

Randomized Controlled Trial Multicenter Study Comparative Study
Re-displacement of stable distal both-bone forearm fractures in children: a randomised controlled multicentre trial.
Displaced metaphyseal both-bone fractures of the distal forearm are generally reduced and stabilised by an above-elbow cast (AEC) with or without additional pinning. The purpose of this study was to find out if re-displacement of a reduced stable metaphyseal both-bone fracture of the distal forearm in a child could be prevented by stabilisation with Kirschner wires. ⋯ Pinning of apparent stable both-bone fractures of the distal forearm in children might reduce fracture re-displacement. The frequently seen complications of pinning might be reduced by a proper surgical technique.

Randomized Controlled Trial Comparative StudyPerioperative myocardial infarctions are common and often unrecognized in patients undergoing hip fracture surgery.
The aim of this prospective cohort study was to assess the incidence and characteristics of acute myocardial infarction in patients undergoing surgery for acute hip fracture. ⋯ Epidemiologic study, level III.
