Abstract
Background: A sternoclavicular (SC) joint dislocation is a rare injury, accounting for 1% of all traumatic joint dislocations. Dislocation of the SCJ is a rare injury and typically requires high-energy forces applied directly or indirectly to the joint. Although anterior sternoclavicular dislocations are more common because of the strength of the posterior joint capsule, posterior sternoclavicular dislocations tend to be more morbid because of the risk of tracheal, esophageal, or neurovascular compression. Even after appropriate treatment of the initial dislocation, patients can occasionally have persistent SCJ instability that may present as pain and scapular dyskinesia.
Objective: To perform a systematic review on results of reconstruction of anterior sternoclavicular joint dislocation via figure of eight graft, aiming at highlighting clinical and functional outcomes of this technique.
Patients and Methods: This is a systematic review study and meta-analysis on human subjects studied in different literatures collected from different medical websites up to December 2022 that dealing with the reconstruction of anterior sternoclavicular joint dislocation via figure of eight graft, aiming at highlighting clinical and functional outcomes of this technique. The study was performed in the Orthopedic Surgery Department, Faculty of Medicine, Ain Shams University along the period from August 2022 to January 2023.
Results: The meta-analysis for postoperative complications showed non-significant difference (P= 0.068). This indicated that this technique had low risk of complications. Forest plot and pooling of data using random-effects method (REM) with 95% CI found minor heterogeneity (I2 =38.4%) non-significant difference (p >0.05) in complications of this operative technique. The funnel plot for postoperative complications found no evidence of publication bias with symmetrical funnel plot. Rank correlation test and regression analysis for funnel plot asymmetry was insignificant (r = 0.0852, p =0.068) for postoperative complication of anterior sternoclavicular joint dislocation operated by 8-shaped autologous graft.
Data Sources: Medline databases (PubMed, Medscape, ScienceDirect. EMF-Portal) and all materials available in the Internet till 2020.
Conclusion: SC joint reconstruction, using a gracilis graft, results in a prolonged improvement in shoulder function in most patients with symptomatic chronic anterior SC instability. The technique aims at reducing the risk of serious vascular and functional complications, but extreme care is still needed during the procedure.
