Early repair of traumatic rotator cuff tears improves functional outcomes.

BACKGROUND: The impact of surgical timing on outcomes involving traumatic rotator cuff tears (RCTs) remains uncertain. The purpose of this study was to determine how functional outcomes are affected by surgical timing in traumatic RCTs. METHODS: We performed a retrospective review of patients with repair of traumatic full-thickness RCTs. Preoperative magnetic resonance imaging scans were evaluated by 2 blinded reviewers to measure RCT area and muscular atrophy. Functional outcomes were assessed via the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, Simple Shoulder Test score, and visual analog scale (VAS) pain score. Patients were divided into 4 groups based on the time from injury to surgery: 0-2 months (group 1), 2-4 months (group 2), 4-6 months (group 3), and 6-12 months (group 4). Multivariate analysis was performed to assess the impact of surgical timing on functional outcomes. A subanalysis was performed to assess outcomes in patients who underwent surgery within 3 weeks of injury. RESULTS: The study included 206 patients (150 men and 56 women) with a mean age of 60.0 ± 9.7 years and a minimum of 24 months' clinical follow-up (mean, 35.5 months; range, 24-54.4 months). The average tear area was 8.4 ± 6.3 cm2 in group 1 (66 patients), 5.8 ± 5.1 cm2 in group 2 (76 patients), 5.1 ± 4.6 cm2 in group 3 (29 patients), and 3.7 ± 3.1 cm2 in group 4 (35 patients) (P < .001). There were significant differences between the 4 cohorts in the final postoperative ASES score (P = .030) and VAS pain score (P = .032). The multivariate regression demonstrated that patients who underwent surgery within 4 months of injury had estimated improvements of 10.3 points in the ASES score (P = .008), 1.8 points in the Simple Shoulder Test score (P = .001), 8.6 points in the SANE score (P = .033), and 0.93 points in the VAS pain score (P = .028) compared with patients who underwent surgery later. The subanalysis demonstrated that patients who underwent surgery within 3 weeks of injury (n = 13) had significantly better VAS (P = .003), ASES (P = .008), and SANE (P = .019) scores than patients who underwent surgery at between 3 weeks and 4 months after injury (n = 129). CONCLUSIONS: This study demonstrates that surgical repair of traumatic RCTs results in significant improvements in functional outcomes for all patients; however, patients who undergo surgery within 3 weeks can expect the best functional outcomes, with a drop in function in patients who undergo surgery >4 months after injury.

Performance in major league baseball pitchers after surgical treatment of thoracic outlet syndrome.

INTRODUCTION: Thoracic outlet syndrome (TOS) can be a career-threatening injury for Major League Baseball (MLB) pitchers, often requiring surgical management. The purpose of this study is to determine the efficacy of surgical management for TOS as a function of return to play and quantitative pitching metrics. METHODS: 27 MLB pitchers underwent surgical treatment for TOS between January 2001 and December 2017. Analysis of pre and postoperative pitching metrics were used to assess the effect of surgery on 20 pitchers who returned to pitch in MLB. All pitching metrics were compared via assessing performance two years prior to surgery and two years after surgery. For 20 pitchers who returned to pitch, MLB pitching metrics of earned run average (ERA), walks plus hits per innings pitched (WHIP), wins above replacement (WAR), and average fastball velocity were used to assess a pitcher's ability to return to preoperative performance level. RESULTS: Of the 27 pitchers, 20 pitchers were diagnosed with neurogenic thoracic outlet syndrome (NTOS) and seven with venous thoracic outlet syndrome (VTOS). The average age of onset of TOS was 28.6 years. There was no significant difference between the age of onset between the NTOS and VTOS populations (p = 0.272). Of the 27 pitchers, 20 (74.1%) were able to return to MLB play at a mean of 297 days (range, 105-638 days) after surgery. Pitching metrics demonstrated that pitcher ERA remained inferior postoperatively compared to baseline preoperative performance (3.66 vs 4.50, p = 0.03). Fastball velocity (p = 0.94) and strike percentage (p = 0.50) were equivalent to pre-injury performance. CONCLUSION: 74% of professional pitchers who undergo surgical intervention for TOS are able to return to play at the MLB level. With regards to performance, the majority of metrics were unchanged from prior to surgery, indicating return at a similar functional level.
