Arthroscopic Stabilization for Chronic Latent Syndesmotic Instability.

ABSTRACT: Subtle syndesmotic instability not evident on radiography can result in chronic ankle pain. The diagnosis is uncommon, and arthroscopic evaluation remains the gold standard for diagnosis. Definitive surgical management can be performed at the time of diagnosis. Patients with 2 to 4 mm of diastasis of the syndesmosis or translation can be treated with debridement alone, and patients with 4 mm or more of diastasis or translation can be treated with arthroscopic debridement and reduction followed by percutaneous stabilization. Percutaneous stabilization is accomplished by a TightRope technique, which involves passing 1 or 2 suture buttons through all 4 cortices of the distal tibia and fibula. This technique is used in lieu of the traditional syndesmotic screw, which requires a subsequent operation for removal.

Project description:BackgroundRecurrent shoulder instability is an orthopedic problem with potentially long-term functional ramifications. Although arthroscopic stabilization has become increasingly utilized over open stabilization, optimal surgical intervention to minimize recurrent instability remains controversial.MethodsThe PearlDiver Mariner database was queried for all cases of open and arthroscopic shoulder stabilization from 2010 to 2019. Utilization trends were aggregated after identifying cohorts of 107,210 and 13,217 patients who respectively underwent arthroscopic or open stabilization using Current Procedural Terminology codes. Subsets from those cohorts with laterality-specific International Classification of Diseases, Tenth Revision codes for shoulder instability were used to evaluate 2-year rates of recurrent instability (presence of shoulder dislocation or revision open or arthroscopic stabilization). Linear regression and chi-squared analysis were used to analyze utilization trends and to compare recurrent instability.ResultsArthroscopic stabilization comprised 90% of all stabilization procedures with annual utilization continuing to increase into 2019. Latarjet utilization increased from 15% to 42% of all open stabilization procedures while open Bankart repair utilization decreased from 56% to 35%. The rate of recurrent instability was 10.2% after arthroscopic stabilization and 12.3% after open stabilization (P = .01). Rates of redislocation (4.0% vs. 2.6%, P < .01), conversion to shoulder arthroplasty (1.2% vs. 0.4%, P < .01), and revision open stabilization (6.8% vs. 2.3%, P < .01) after index open stabilization were significantly higher than after index arthroscopic stabilization. There was no difference in revision stabilization or dislocation rates between open procedures.ConclusionDespite increasing utilization of coracoid transfer, arthroscopic stabilization is still the dominant modality used for surgical treatment of shoulder instability and in our analysis, showed lower 2-year rates of dislocation, revision open stabilization, and conversion to shoulder arthroplasty.
