Keywords: Biceps pathology, coracohumeral distance, rotator cuff, superior humeral migration.
Objectives: The aim of the study was to investigate the relationship between biceps pathologies and radiological measurements in massive rotator cuff tears treated arthroscopically.
Patients and methods: Between December 2015 and December 2018, a total of 145 patients (56 males, 89 females; mean age: 62.2±9.7 years; range, 28 to 87 years) with supraspinatus and/or infraspinatus full-thickness tear larger than 3 cm and who underwent arthroscopic rotator cuff repair were retrospectively analyzed. Biceps pathologies detected during arthroscopy were divided into four groups. Group 1: biceps tendinitis or without biceps pathology; Group 2: biceps partial/degeneration tear; Group 3: biceps dislocation/instability; Group 4: complete biceps head rupture. Radiological measurements were calculated from the preoperative magnetic resonance imaging and anteroposterior X-ray images of the patients.
Results: A total of 65.5% of the lesions were on the right arm and 34.5% were on the left arm. All patients had posterior superior rotator cuff tears which could be surgically repaired. A total of 22.1% of the patients had no biceps tendinitis/biceps pathology, 20.7% had biceps instability/dislocation, 28.3% had biceps degeneration/partial rupture, and 29% of patients had biceps total rupture. Patients in Group 4 had a statistically significantly higher superior migration of the humeral head distance (p=0.012) than Group 2, and patients in Group 2 had a statistically significantly higher coracohumeral distance (p=0.042) than patients in Group 4. There was no significant difference in the other measurements among the groups.
Conclusion: The long head of the biceps, of which function has not yet been clearly elucidated, is one of the superior and anterior stabilizing forces of the humeral head.
