Error replication as an instructional strategy in simulation‐based procedural learning

Medical Education, EarlyView.
Abstract Background Errors are an inevitable part of clinical learning, yet procedural training commonly emphasises error avoidance. This study examined the effect of deliberate replication of predefined procedural errors (Error Replication; ER), compared with error avoidance training (EAT), on post‐test performance, retention and transfer in surgical ...

Treatment Trade‐Offs and Choices for Femoral Fractures: A Systematic Review and Meta‐Analysis

Orthopaedic Surgery, Volume 17, Issue 5, Page 1298-1313, May 2025.
This review examines the trade‐offs between surgical intervention and traction therapy for adult and elderly patients with femoral fractures and surgical contraindications, particularly in resource‐limited settings. While intramedullary nailing may offer better clinical outcomes, traction therapy is often preferred due to limited surgical resources ...

Non-Uniform Clearance between Rotor Surfaces and Its Effect on Machine Performance in Twin-Screw Compressors [PDF]

, 2012
The performance of twin-screw compressors is primarily affected by the clearance between a pair of meshing rotors. This study proposes a method for calculating the normal clearance along the contact line between rotors using two normal rack curves, which

Clinical Outcomes of an Improved Arthroscopic Suture‐Bridge Technique Assisted by a “5 O'clock” Portal for Acute Bony Bankart Lesions

Orthopaedic Surgery, EarlyView.
This modified arthroscopic suture‐bridge technique, utilizing a unique “5 o'clock” portal, achieves reliable perpendicular fixation for bony Bankart lesions, reducing mean glenoid bone loss from 18.2% to 2.5% (p < 0.001) with a 97.2% healing rate and 80% return‐to‐sport rate. ABSTRACT Purpose Bony Bankart lesion is a primary cause of traumatic shoulder

Role of screw proximity in the fixation of transverse patellar fractures with screws and a wire

Journal of Orthopaedic Surgery, 2018
Purpose: Clinical and biomechanical studies have reported that using supportive screws and a wire instead of the common Kirschner wires for modified tension band wiring improves the stability of fractured patellae.
