Pain associated psychological distress is more strongly associated with shoulder pain and function than tear severity in patients undergoing rotator cuff repair.

Background: Psychological distress has been associated with declining shoulder function in patients with rotator cuff tears (RCTs). Thus, we aimed to 1) evaluate the absence or presence of differences in shoulder pain, function, or pain-associated psychological distress in patients with increasing RCT severity and 2) assess whether psychological distress is associated with shoulder pain and function while adjusting for RCT severity. Methods: Consecutive patients who underwent rotator cuff repair and completed the optimal screening for prediction of referral and outcome (OSPRO) survey from 2019 to 2021 were included. OSPRO is composed of 3 domains that estimate pain associated psychological distress (negative mood, negative coping, and positive coping). Demographics, tear characteristics, and three patient reported outcomes (PRO), including the visual analog scale (VAS), Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) were collected. Patients were analyzed with analysis of variance and chi-square tests and stratified based on severity of RCTs into three groups: partial-thickness, small-to-medium full-thickness, and large-to-massive full-thickness tear. Linear regression analysis was used to evaluate the association between OSPRO scores and PROs, adjusting for severity of RCT. Results: Eighty-four patients were included: 33 (39%) had partial-thickness, 17 (20%) had small-to-medium full-thickness, and 34 (41%) had large-to-massive tears. Regarding PROs and psychological distress, there were no significant differences amongst the three cohorts. In contrast, multiple significant associations between psychological distress and PROs were found. Within the negative coping domain, fear avoidance dimensions demonstrated the strongest correlation to PROs: fear-avoidance behavior for physical activity (ASES Beta -0.592, P < .001; VAS 0.357, P < .001) and work (ASES Beta -0.442, P < .001; VAS 0.274, P = .015). Several other dimensions within the negative coping, negative mood, and positive coping domains also demonstrated significant associations to PROs. Discussion: These findings suggest that in patients undergoing arthroscopic rotator cuff repair, preoperative psychological distress can more strongly influence patient perception of shoulder pain and diminished shoulder function than RCT severity.

Regional anesthesia is associated with improved metastasis free survival after surgical resection of bone sarcomas.

There is increasing evidence that perioperative factors, including type of anesthesia, may be an important consideration regarding oncological disease progression. Previous studies have suggested that regional anesthesia can improve oncological outcomes by reducing the surgical stress response that occurs during tumor resection surgery and that may promote metastatic progression. The purpose of this study is to provide the first robust investigation of the impact of adding regional anesthesia to general anesthesia on oncological outcomes following sarcoma resection. One hundred patients with bone sarcoma were retrospectively analyzed in this study. After adjusting for confounding variables such as age and grade of the tumor, patients with bone sarcoma receiving regional anesthesia in addition to general anesthesia during resection had improved metastasis free survival (multivariate hazard ratio of 0.47 and p = 0.034). Future studies are needed to confer the beneficial effect of regional anesthesia, and to further investigate the potential mechanism. Clinical significance: The results from this study provide evidence that regional anesthesia may be advantageous in the setting of bone sarcoma resection surgery, reducing pain while also improving oncological outcomes and should be considered when clinically appropriate.

Subscapularis management in stemmed and stemless total shoulder arthroplasty: a surgeon decision-making analysis study.

Background: Stemless total shoulder arthroplasty (TSA) continues to grow in popularity as an evolution of stemmed humeral implants. Proposed advantages include bone preservation and ease of potential revision. However, absence of a stem may necessitate a change in subscapularis takedown approach. Specifically, there is theoretical concern about violation of supportive bone with lesser tuberosity osteotomy when using a stemless device. Therefore, the goal of this study was to identify if surgeons change their subscapularis takedown preference when performing stemless vs. stemmed TSA. Methods and materials: Data from a consecutive series of patients who underwent stemmed and stemless TSA at an academic institution were collected. The subscapularis management technique was documented. Subscapularis takedown techniques were divided into 2 groups: soft-tissue approach (subscapularis tenotomy or peel) and bony approach (lesser tuberosity osteotomy). Historical preference for each surgeon was determined by evaluating techniques employed using stemmed TSA. A Cramers V analysis was run to determine the strength of association between this historical preference and subscapularis management technique used for stemless TSA. Results: One hundred and fifty-four patients were included in this analysis. There were 72 and 82 stemmed and stemless arthroplasty cases performed, respectively. Of the 154 patients, 50.6% were women. The average age of patients was 64.2 years. Four surgeons were included in this study. In all, there were 79 and 75 bony and soft-tissue subscapularis techniques, respectively. The historical preference for 3 of the surgeons was a subscapularis bony approach, and the historical preference for one of the surgeons was a soft-tissue approach. A Cramer's V analysis was used to measure the relative strength of association between patient factors, historical subscapularis management preference, and subscapularis takedown approach in stemless TSA. Our analysis yielded a value of 0.65 (P < .01), indicating a redundant association between subscapularis management approach used between stemmed and stemless implant per surgeon. Conclusion: In determining subscapularis tendon management strategy, in surgeons who performed stemmed TSA before stemless TSA, the subscapularis takedown approach used for stemless TSA is strongly associated with surgeon's historical preference for stemmed TSA. Future research will be needed to determine the clinical ramifications of this finding.
