“…The CHD is a measurement of the shortest distance from the coracoid process cortex to the humeral cortex, and there are trans-verse positions and oblique sagittal positions. Relevant studies have shown that the normal value of the CHD on MRI is 8.7-11 mm [23,37,38]. Leite et al, suggested that the optimal sensitivity and specificity for predicting SSC tears was a CHD of 7.95 mm [13].…”

To identify factors associated with subscapularis (SSC) tears and provide a theoretical basis for clinical diagnosis, we included studies related to subscapularis tears published before February 1, 2023. We screened for six predictors across previous studies for the meta-analysis. The predictors included age, sex, coracoid overlap (CO), coracohumeral distance (CHD), impairment of the long head of the biceps tendon (LHB), and dominant arm. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the studies. The risk ratios (RRs) and the weighted mean differences (WMDs) were used to evaluate the effect size of categorical variables and continuous variables, respectively. The Egger test was used to assess the publication bias of the studies. Ten studies were included from seven countries. A total of 2 126 patients were enrolled, of whom 1 041 had subscapularis tears and 1 085 did not. The study showed that age (WMD, 4.23 [95% CI, 2.32–6.15]; P<.00001), coracoid overlap (WMD, 1.98 [95% CI, 1.55–2.41]; P<.00001), coracohumeral distance(WMD, –1.03 [95% CI, –1.17– –0.88]; P<.00001), and an injury of the long head of the biceps tendon (RR, 4.98 [95% CI, 3.75–6.61]; P<.00001) were risk factors for subscapularis tears. These risk factors can help clinicians identify subscapularis tears early and select appropriate interventions. The level of evidence is 3.

“…Both these parameters demonstrated being excellent SubS lesion predictors in several studies, however they translate different anatomic particularities of the shoulder gridle. The CHD corresponds to the smaller distance between the humerus lesser tuberosity and the coracoid, and represents the space available for de SubS (2,7,(19)(20)(21). This space can be altered by pathologies affecting the humerus lesser tuberosity or the coracoid, such as fracture mal union, osteophytes, cysts or anomalies of the lesser tuberosity, SS tendon calcifications or even abnormal coracoid anatomy (2,7,(19)(20)(21).…”

As stated previously, other papers have also showed that the CHD can also be influenced by the presence of SS tears, and the phenom is explained by superior subluxation of the humeral head in these patients, that results in a greater humeral cross-section posteriorly to the coracoid process, and secondary subcoracoid impingement (10).…”

Backgroud. Many subscapularis (SubS) lesions represent the result of the progression of anterosuperior cuff tears, although their pathophysiology is still relatively unknown. The goal of this paper was to determine the influence of supraspinatus tears in the development of subcoracoid impingement and therefore SubS tears. Methods. This is a retrospective, controlled and single-blinded study. We analyzed 301 patients with rotator cuff pathology and an MRI study. The coraco-humeral distance and coracoid overlap were measured. The presence of supraspinatus and subscapularis lesions were also evaluated. Results. Supraspinatus tears were found to be associated with the presence of subscapularis tears (p = 0.003). A significant relationship (p = 0.002) was achieved between supraspinatus tears and inferior coraco-humeral distance, with average values of 8.4 ± 2.9 mm and 10.2 ± 3.2 mm in shoulders with and without supraspinatus tears respectively. On the opposite side, there wasn't a significant association between supraspinatus tears and the coracoid overlap. Conclusions. This paper is, to our knowledge, the first to study the influence of supraspinatus tears in different parameters implied in subscapularis tears pathology, representing also the largest published sample on this theme, including 301 patients. Finally, this study offers an explanation for anterosuperior cuff progression pathophysiology, confirming that supraspinatus full thickness tears can lead to a secondary subcoracoid impingement and thus subscapularis tears.
