Instability Severity Index Score predicts recurrent shoulder instability after arthroscopic Bankart repair

Purpose: The Instability Severity Index (ISI) Score was developed to preoperatively assess the risk of recurrent shoulder instability after an arthroscopic Bankart repair. This study aims to validate the use of ISI Score for predicting the risk of recurrence after an arthroscopic Bankart repair in a heterogeneous population and proposes an appropriate cut-off point for treating patients with an arthroscopic Bankart repair or otherwise. Methods: This study analysed 99 shoulders after a traumatic dislocation that underwent arthroscopic Bankart repair with at least 3 years follow-up. Patients were divided into subcategories based on their respective ISI Score. Recurrence includes either a postoperative dislocation or perceived instability. Results: The overall recurrence rate was found to be 26.3%. A significant correlation was identified between ISI Score and the recurrence rate (odds ratio [OR]: 1.545, 95% confidence interval [CI]: 1.231–1.939, p &lt; 0.001). Furthermore, ISI Score 4–6 (OR: 4.498, 95% CI: 1.866–10.842, p &lt; 0.001) and ISI Score &gt; 6 (OR: 7.076, 95% CI: 2.393–20.924, p &lt; 0.001) both had a significantly higher risk of recurrence compared to ISI Score 0–3. In ISI Score subcategories 0–3, 4–6 and &gt;6, the recurrence rate was, respectively, 15.4%, 40.7% and 71.4%. Conclusion: ISI Score has predictive value in determining the recurrence risk of shoulder instability following an arthroscopic Bankart repair in a heterogeneous population. Based on the findings of this study, we recommend using arthroscopic Bankart repair in patients with ISI Score 0–3. Clinical and shared decision-making are essential in the group with ISI Score 4–6, since the recurrence rate is significantly higher than in patients with ISI Score 0–3. Arthroscopic Bankart repair is not suitable for patients with ISI Score &gt; 6. Level of Evidence: Level III.</p

Ninety-day complication rate based on 532 Latarjet procedures in Dutch hospitals with different operation volumes

Background: In this study, we aimed to provide insight into the 90-day complication rates following the Latarjet procedure. Data from 2015 were collected from multiple hospitals in the Netherlands, with different volumes of Latarjet procedures. Our second aim was to examine which patient and surgical factors were associated with complications.Methods: We conducted a retrospective chart review of 13 hospitals between 2015 and 2022. Data regarding complications within 90 days of Latarjet procedures were extracted. The effect of sex, age, body mass index (BMI), smoking, previous shoulder operations, fixation material, hospital volume, screw size, and operation time on the complication rate was assessed by multivariable logistic regression analysis.Results: Of the 532 included patients, 58 (10.9%) had complications. The most common complications were material failure (n = 19, 3.6%) and nerve injury (n = 13, 2.4%). The risk of complications was lower for male patients than for female patients (odds ratio, 0.40; 95% confidence interval, 0.21-0.77; P = .006). Age, BMI, smoking, previous shoulder operations, type of fixation material, hospital volume, screw size, and operation time were not associated with complications.Conclusion: The 90-day complication rate after the Latarjet procedure was 10.9% and was higher in female patients than in male patients. Age, BMI, smoking, previous shoulder operations, type of fixation material, hospital volume, screw size, and operation time did not affect complication rates. We advise setting up a national registry to prevent under-reporting of complications.</p
