Abstract

The pathoanatomy and biomechanics of elbow instability have been previously reported; however, few researchers have dealt with the operative management and clinical consequence of recurrent elbow instability. Recent studies on arthroscopic lateral collateral ligament (LCL) complex repair have reported successful outcomes similar to those achieved by open repair. We aimed to determine the validity of arthroscopic repair of the LCL complex in elbows with unstable dislocation with or without intra-articular fracture. Eighteen consecutive patients who had undergone arthroscopic repair of the LCL complex for unstable dislocation of the elbow with or without intra-articular fracture and who were followed for at least 12 months were included in the study. Ligament injury combined with coronoid and/or radial head fractures were treated with arthroscopic technique. Pain, range of motion, clinical outcomes based on the Mayo Elbow Performance Score (MEPS), and surgical complications were evaluated. At 12 months follow-up, all 18 patients demonstrated complete settlement of the instability and mean (and standard deviation) extension of 1.7 ± 3.8°, flexion of 138.3 ± 3.8°, supination of 88.6 ± 5.3°, and pronation of 88.2 ± 5.6°. The average...Continue Reading

Biomechanics

Biomechanics examines the generation of internal forces within the body and investigates the effects and control of forces that act on or are produced on tissues. Here are the latest discoveries.
