Significant differences were observed between rTSA and aTSA patients in terms of age, version angle, inclination angle, erosion depth, and humeral head diameter. Females accounted for 53.1% of the dataset and were generally older, with less retroversion and subluxation compared to males. Regionally, 61% of procedures were performed in North America, 25% in Europe, and 14% in Oceania. rTSA was more common than aTSA across all continents, with the highest proportion found in Europe (86%).

Despite its known anatomical and stabilizing roles, the histological composition of the ANL remains unclear. The first article to describe its nature introduced the concept of a wrap-around ligament. A wrap-around ligament is defined as “any tendon that bends around a bony pulley or threads through a fibrous 1 en route to its insertion”. These ligaments are often fibrocartilaginous due to an adaptation to compressive forces. During pronation and supination the ANL is compressed against the RH. Therefore, the authors hypothesize that the ANL contains (fibro)cartilaginous tissue where the ligament is compressed against and experiences friction from the RH. Understanding the precise histological nature of the ANL is essential for surgical procedures involving the RH, such as fracture osteosynthesis, in which hardware placement may lead to complications.</div></div><div><h3>Methods</h3><div>This study consisted of 2 components: a scoping review and a histological analysis.

The optimal configuration and type of sutures for LTO repair are unknown. The effect of variable surgeon strength on repair is similarly an unknown factor and may play a role in construct repair security. This study measured, in vitro, the effect of suture number and the effect of surgeon manual strength on repair.

The purpose of this study is to determine the risk factors associated with failure of CC reconstruction, regardless of the fixation method used.</div></div><div><h3>Methods</h3><div>A systematic review was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Medline, Embase, and Cochrane were searched through November 2024 for studies analyzing the failures of CC reconstructive surgery. Studies that quantified risk factors for CC reconstruction failure were included.</div></div><div><h3>Results</h3><div>Seven studies comprising 781 CC reconstructions were analyzed with an overall failure rate of 19.1%. Clavicle tunnel malposition in anatomic reconstructions was the most cited risk factor for failure. Position was defined as either the distance from the lateral aspect of the clavicle to the tunnels or as a ratio between this distance and the length of the clavicle. Three studies cited increased failure risk with medial malposition of the conoid or trapezoid tunnels. Specific parameters included conoid tunnel ratio &gt;0.25, (odds ratio (OR) = 5.67), trapezoid ratio &gt;0.15 (OR = 4.2), conoid tunnel &gt;47 mm (OR = 4.67), and trapezoid tunnel &gt;24 mm (OR = 4.2). Lateral conoid tunnel malposition with a conoid tunnel ratio &lt;0.20 (OR = 40) was also noted to increase failure risk. Another study identified increased risk of failure when surgeons use tunnel ratios instead of tunnel distance in mm intraoperatively (OR = 4.609). Placement of a lateral coracoid button, as opposed to a central button, was cited in 2 studies as significant risk factors (OR = 9.614, 13.87). Other risk factors included osteoporosis (OR = 8.652), weight-bearing before 6 weeks from surgery (OR = 6.4), surgery &gt;6 weeks from initial injury (OR = 2.65), osteolysis (OR = 4.386), patient age &gt;40 (OR = 3.14), and open reconstruction (OR = 4.25).</div></div><div><h3>Conclusions</h3><div>Conoid and trapezoid tunnel malposition, both medially and laterally, were significantly associated with an increased risk of failure. Additionally, patient age, osteoporosis, osteolysis, time to weight bearing after surgery, delayed presentation of more than 6 weeks from initial injury, should be considered when considering surgical intervention.</div></div>","PeriodicalId":34444,"journal":{"name":"JSES International","volume":"9 6","pages":"Pages 1965-1971"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145468888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
