[Suprapectoral mini-open biceps tenodesis - functional and sonographic results]

Area of Science:

• Orthopedic Surgery
• Musculoskeletal System
• Shoulder Joint Anatomy

Background:

• Evaluating the efficacy of suprapectoral mini-open tenodesis for the long head of the biceps (LHB) tendon.
• Comparing extraosseous (Group I) versus intraosseous (Group II) fixation techniques for LHB tenodesis.

Purpose of the Study:

• To assess the effectiveness of suprapectoral mini-open tenodesis of the LHB tendon using ultrasound.
• To compare the outcomes of extraosseous versus intraosseous fixation methods.

Main Methods:

• 25 patients underwent LHB tenodesis, with fixation either extraosseous (n=12) or intraosseous (n=13).
• Follow-up averaged 21 months, assessing tendon fixation via ultrasound and evaluating shoulder function (SST, CMS, LHB score).

Main Results:

• Intraosseous fixation had a lower failure rate (8%) compared to extraosseous fixation (25%).
• Significant improvements were noted in shoulder flexion, abduction, external rotation, and pain levels post-surgery.
• No significant differences in functional scores (CMS, SST, LHB score) were found between the two fixation groups at follow-up.

Conclusions:

• Intraosseous fixation of LHB tenodesis demonstrates a lower failure rate than extraosseous fixation.
• Suprapectoral mini-open LHB tenodesis is an effective surgical alternative yielding good to excellent clinical results.
