Clinical Approach to Inconclusive Subscapularis Tear Diagnosis: a Meta-analysis

Int J Sports Med DOI: 10.1055/a-2158-8278To 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 ...
