Introduction: The long head of biceps tendon (LHB) score was designed to clinically assess LHB pathologies. Purpose of this study was to prospectively assess patients with LHB pathologies preoperatively and after LHB surgery using the LHB score.
Materials and methods: Fifty-seven patients (29 f/28 m, Ø age 61.0 years), showing clinical signs of LHB pathologies, were prospectively included into this study. In 43 patients LHB pathologies could be confirmed intraoperatively. Among these, in 26 patients a biceps tenodesis (group I; 8 f/18 m, Ø age 61.2 years), and in 17 patients a biceps tenotomy was performed (group II; 12 f/5 m, Ø age 64.2 years). In 14 patients no intraoperative correlate concerning the biceps symptoms could be found (group III; 9 f/5m, Ø age 56.8 years). In these patients no further LHB treatment was carried out. The clinical evaluation contained the Constant score (CS) as well as the LHB score preoperatively and 2 years postoperatively.
Results: The CS improved significantly in all the three groups [group I: 41.7 (20-70) to 81.3 (62-100); group II: 42.2 (18-66) to 75.3 (41-84); group III: 45.7 (22-77) to 72.9 (48-85)] (p < 0.05). Also the LHB score increased significantly in all three groups [group I: 74.3 (41-97) to 94.2 (80-100); group II: 73.4 (57-97) to 84.2 (49-100); group III: 71.1 (58-80) to 90.8 (70-100)] (p < 0.05). Compared to group II, group I showed significant better results in the total LHB score and in the cosmetic result (p < 0.05).
Conclusions: We recommend that patients with LHB pathologies are evaluated using the LHB score, since it provides LHB related information and is a proper tool to assess the clinical outcome after surgery. However, the score is not appropriate to detect LHB pathologies preoperatively.
Level of evidence: II.
