The purpose of our study was to look at the combined construct of knotted vs. knotless medial row and suture vs. suture tape, focusing primarily on re-tear rates following surgery.Methods: A retrospective observational study of 343 consecutive patients undergoing arthroscopic double row, 4-anchor rotator cuff repair from February 2014 to March 2020 was conducted. Univariate and multivariate statistics were used to assess differences in demographics, comorbidities and tear characteristics between patients who experienced a symptomatic re-tear and those who did not.Results: The overall symptomatic re-tear rate was 7.6%. Patients who had a knotted medial row repair had a significantly lower rate of re-tear (4.7 vs. 11.3%, p = 0.022). Patients that had a knotted medial row and suture tape repair were significantly less likely to experience a re-tear (OR: 0.180, p = 0.001).Discussion: The use of suture tape and a knotted medial row repair decreases the incidence of symptomatic re-tear following rotator cuff repair. The combined construct of suture tape and a knotted medial row in rotator cuff repair decreases the risk for symptomatic re-tear following surgery.","PeriodicalId":36705,"journal":{"name":"Shoulder and Elbow","volume":"1 1","pages":"33-39"},"PeriodicalIF":1.5,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10649482/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42082505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study evaluated whether SA is associated with 1) longer in-hospital lengths of stay (LOS) 2) readmissions 3) medical complications and 4) costs.Methods: A retrospective nationwide Medicare analysis from 2005 to 2014 was performed. Inclusion criteria were patients with SA undergoing RSA for the treatment of glenohumeral osteoarthritis.

Methods The Westlaw legal database was queried for all cases involving humeral fractures. Patient demographics, causes cited for litigation, case outcomes, and indemnity payments were collected to determine common factors that lead plaintiffs to pursue legal action. Results Fifty-seven cases were identified that met inclusion criteria. The mean plaintiff age was 52.5 years with 61% female. The most common category of negligence was treatment error, which occurred in 29 claims (51%). The most common types of damages incurred were functional limitation (40%), nerve injury (32%), and malunion/nonunion (26%). Overall, 42 cases (74%) resulted in a defense verdict.

Methods Five databases were screened until December 18, 2022. The included RCTs were assessed for risk of bias, and the endpoints were summarized as mean difference/standardized mean difference (MD/SMD) or risk ratio (RR) with the 95% confidence interval (CI) in a random-effects model. Results Seven RCTs with 510 patients (TXA = 261 and control/placebo = 249) were analyzed. The overall risk of bias was “low” and “unclear” in four and three RCTs, respectively. The mean operative time (n = 5 RCTs, MD = −9.64 min, 95% CI [−15.74, −3.54], p = 0.002) and mean postoperative pain score on postoperative day 1 (n = 5 RCTs, MD = −0.56, 95% CI [−1.06, −0.05], p = 0.03) were significantly reduced in the TXA group compared with the control group. However, there were no significant differences between both groups regarding visual clarity, amount of irrigation solution, and estimated intraoperative blood loss. Conclusion Among patients undergoing ARCR, preoperative TXA did not reduce intraoperative blood loss or improve visual clarity.

Classically, this syndrome is characterized by craniosynostosis, midface hypoplasia, and symmetrical syndactyly of hands and feet resulting from embryonic anomalies during the third week of gestation. It is also associated with a variety of abnormalities of the viscera, involving the neurological, genitourinary, and cardiorespiratory systems. Glenohumeral manifestations of Apert syndrome include glenoid dysplasia, an oblong humeral head with a prominence of the greater tuberosity, acromial prominence, and inferior subluxation of the glenohumeral joint. This pathological anatomy results in progressive degenerative changes, synchondrosis, and restriction in shoulder joint mobility, particularly in flexion and abduction. While surgical options for the accompanying deformities of the feet and spine are described, interventions for shoulder pathology are not well-defined. Joint replacement surgery could offer such patients pain relief and improved function.

We believe this risks fracture displacement and imbalance of soft tissues, encouraging malunion and stiffness. A neutral-rotation brace (NRB) maintains an arm position which may prevent this, leading to quicker and superior recovery.Methods: We randomised patients with two- to four-part PHF into 4 weeks of immobilisation with either a SS or NRB, independent of surgery. Range of motion (ROM), subjective shoulder value (SSV), DASH, Constant-Murley (CMS) and Oxford Shoulder (OSS) scores were assessed at 6-weeks, 3-months and 1-year post-injury.Results: The SS group included 11 patients vs 9 in the NRB group. At final follow-up, the SS and NRB groups had mean DASH scores of 42 vs 35, OSS 42 vs 46, CMS 71 vs 86, SSV 84% vs 92%, respectively.

Ultrasound-guided interscalene blocks (ISBs), currently the gold standard for postoperative pain management after shoulder surgery, can be highly operator dependent, time-consuming, and not without complications. We developed a new surgical technique of surgeon-administered intraoperative brachial plexus block in patients undergoing SA open shoulder surgery using the deltopectoral approach. This procedure could be performed after the exposure, either at the beginning or end of the bony work. This procedure is simple, safe, and effective. We did not notice any complications that are typically seen with ISB-like respiratory depression secondary to phrenic nerve palsy, rebound pain after the block wore off, and pain related conversion of outpatient SA to inpatient, over the period of four years (2018-2022). This technique has additional advantages over the established \"gold standard\" ISB in terms of time and cost savings and improved operating room efficiency.","PeriodicalId":36705,"journal":{"name":"Shoulder and Elbow","volume":"15 5","pages":"571-576"},"PeriodicalIF":1.5,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10557931/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41149051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
