Long-term outcomes of open modified inferior capsular shift for traumatic anterior shoulder instability: over 20 years of follow-up

BACKGROUND

This study aimed to assess the long-term outcomes of the open modified inferior capsular shift procedure across more than 20 years in patients with traumatic anterior shoulder instability.

METHODS

Participants in this study comprised 84 patients (86 shoulders; 67 men, 17 women). Mean follow-up was 28.0 years. We compared the recurrent instability rate after surgery, apprehension, revision rate, satisfaction, return to preinjury sporting activity, and patient background characteristics between recurrent and nonrecurrent groups. Twenty-seven patients who were examined directly were evaluated for differences in range of motion and muscle strength between affected and nonaffected sides. Clinical outcome scores used for this study were the Western Ontario Shoulder Instability Index and the Rowe score.

RESULTS

Nine shoulders (10.5%) showed recurrent instability, as dislocation in 3 shoulders and subluxation in 6 shoulders, but no revisions were required. All patients with recurrent instability were males with new trauma. Three shoulders developed recurrent instability ≤5 years after surgery, and the remaining 6 shoulders showed recurrent instability >5 years after surgery. No significant differences in any patient characteristic were identified between the recurrent and nonrecurrent groups. Significant differences between affected and nonaffected sides were seen in the mean active range of motion or muscle strength for external rotation in the anatomic position or in 90° of abduction. Western Ontario Shoulder Instability Index and Rowe score were significantly worse in the recurrent group than in the nonrecurrent group. Patients reported that 84 shoulders (97.7%) were "much better." Most athletes (88.4%) had returned to sports activity at a level >70%.

CONCLUSION

We investigated long-term outcomes of the open modified inferior capsular shift procedure for traumatic anterior shoulder instability. Our data suggest that recurrent instability might result from new trauma even if a long time has passed since the open modified inferior capsular shift procedure, so follow-up should be continued as long as possible after surgery. As in other reports, satisfaction was high and clinical scores were good. We thus believe this surgical method offers good results even after more than 20 years.

Open versus robotic partial nephrectomy: Systematic review and meta-analysis of contemporary studies

OBJECTIVES

To compare perioperative outcomes of robotic-assisted partial nephrectomy (RaPN) with open partial nephrectomy (OPN).

METHODS

Systematically search through PubMed, Embase, ClinicalKey, Cochrane Library, ProQuest, ScienceDirect, Web of Science, and ClinicalTrials.gov for eligible studies was performed to April 11, 2018. A meta-analysis was conducted for studies comparing RaPN and OPN. Confounding variables were assessed by meta-regression or subgroup analysis.

RESULTS

This study included 34 studies with 60 808 patients. Meta-analysis revealed less blood loss, less transfusion, longer operative time, less postoperative complications, lower readmission rate, shorter length of stay, and less estimated glomerular filtration rate (eGFR) decline in RaPN groups. The superiority of RaPN in blood loss was attenuated with highly complex renal masses. The superiority of RaPN in intraoperative complications was strengthened with renal hilar control. The advantage of RaPN in surgical margin was increased in patient with body mass index (BMI) < 28.

CONCLUSIONS

Compared with OPN, RaPN provided lower morbidities and better renal function preservation.

Trends in slipped capital femoral epiphysis: is the rate declining?

PURPOSE

Slipped capital femoral epiphysis (SCFE) is an adolescent hip condition with a high risk of complication. The purpose of this study was to evaluate trends in treatment using a prospectively collected paediatric nationally representative database.

METHODS

A total of 9034 patients undergoing treatment for idiopathic SCFE were selected by querying the Healthcare Cost and Utilization Project's Kids' Inpatient Database for the years 1997, 2000, 2003, 2006, 2009 and 2012. The selected patients were separated based on operative approach and these cohorts were analyzed based on temporal and categorical differences in operative approach, patient demographics and clinical characteristics. Univariate and multivariate analyses were used when appropriate and the Mantel-Haenszel test for trend was used in temporal analysis.

RESULTS

Overall SCFE procedures have decreased 27.5% (p < 0.001). Closed procedures have decreased 28.5% (p < 0.001), while open procedures have decreased 44.8% (p < 0.001). Bilateral closed procedures have increased 7.2% (p < 0.001). The ratio of open to closed procedures decreased in patients aged nine to 12 years and increased in patients aged 13 to 16 years (p < 0.001).

CONCLUSION

Here we report age stratified trends in treatment for idiopathic SCFE using nationally representative data and show an overall decrease in admissions and procedures over time.

LEVEL OF EVIDENCE

Level III, retrospective comparison study.
