Mid-term outcomes of arthroscopic Latarjet procedure in chronic anterior shoulder instability after failed Bankart surgery or with significant glenoid bone loss.

Introduction: Arthroscopic Latarjet surgery is a technique developed to minimize invasive surgical treatment of anterior shoulder instability. However, compared to an open Latarjet operation, it is considered more technically demanding. The aim of our study was to assess its mid-term success rate in the hands of a surgeon with sufficient experience.

[Evaluation of a Combination of Waveform Amplitude Latency and Decrease of Waveform Amplitude Magnitude during Spinal Surgery in Intraoperative Neurophysiological Monitoring of Transcranial Motor Evoked Potentials and Its Incidence on Postoperative Neurological Deficit].

PURPOSE OF THE STUDY This retrospective study investigated the significance of a combination of peak latency of waveform amplitude and waveform amplitude in association with spinal deformities. The correlation with postoperative neurologic deficit was evaluated too. MATERIAL AND METHODS Between January 2007 and January 2018, a group of 113 patients was evaluated in the study who underwent spine surgery using intraoperative neurophysiological monitoring (IONM) focusing on transcranial motor evoked potential (tc-MEP) monitoring.
