Intra-articular arthroscopic biceps tenodesis with interference screw: clinical and isokinetic evaluation

Arthroscopic biceps tenodesis using press-fit bony plug: a case series study

PURPOSE

To assess the feasibility, operative time, clinical outcomes, possible complications, and failure rates of all-through arthroscopic biceps tenodesis using press-fit bony plug technique.

METHODS

This prospective case series study involved 30 skeletally mature patients with long head of biceps pathology (tendinitis after failure of conservative treatment, subluxation, dislocation, or tendon tears). All patients were followed up for 24 months at least.

RESULTS

Twenty-nine patients regained full shoulder and elbow range of motion; one case suffered from reflex sympathetic dystrophy. There was a significant improvement in the constant, ASES, and VAS scores when comparing the pre-operative and post-operative values. The average biceps strength was 96% compared to the opposite healthy side. No cases were complicated by neuro-vascular deficits or failure of the tenodesis.

CONCLUSION

Press-fit biceps tenodesis is safe and accessible with low economic demands. We recommend this technique to be used more often when addressing patients with long head of biceps pathologies.

Biceps tenodesis combined with rotator cuff repair increases functional status and elbow strength

PURPOSE

The aim of the present study was to prospectively evaluate the elbow flexion and supination strengths and the functional outcomes of patients following arthroscopic rotator cuff repair combined with simultaneous biceps tenodesis.

METHODS

19 patients who underwent arthroscopic rotator cuff repair and biceps tenodesis with at least 24 months of follow-up were included. Patients were evaluated using a visual analog scale (VAS) for bicipital groove pain, American Shoulder and Elbow Surgeons (ASES), and constant scores (CS), biceps apex distance (BAD), elbow flexion, and supination strengths.

RESULTS

The VAS for biceps groove measurement averages in the postoperative 6th, 12th, and 24th months was lower in comparison to preoperative data and was considered to be statistically significant (p < .05). The constant score, an average of all postoperative measurements and scores, was found to be higher than preoperative values and was considered to be statistically significant (p < .01). There was a significant difference in the operated and non-operated forearm supination and elbow flexion muscle strength measurements at the postoperative 3- and 6-month follow-ups (p < .01).

CONCLUSION

Arthroscopic biceps tenodesis into the anchors of the lateral row in combination with rotator cuff repair provides an increase in the strength of elbow flexion and forearm supination, while decreasing pain.

Current Controversies and Decision-Making in the Management of Biceps Pathologies

»

Biceps tendon pathologies include a spectrum of injuries that range from mild tendinosis to complete tendon rupture.

»

Tendinosis, the most common pathology, occurs more frequently with age and is likely related to chronic degeneration. On the other side of the spectrum of severity lies a rupture of the long head of the biceps tendon (LHBT), which may be accompanied by injury to the glenoid labrum.

»

Superior labral anterior-posterior (SLAP) tears are frequently associated with biceps pathology. Surgical management for injuries of the bicipital-labral complex includes biceps tenodesis or tenotomy and SLAP repair. A consensus as to which of these procedures is the optimal choice has not been reached, and management may ultimately depend on patient-specific characteristics.

»

Due to the relatively low incidence of distal biceps tendon rupture, agreement on the optimal management strategy has not been reached. Surgical repair, or reconstruction in the case of a chronic rupture, is often chosen. However, nonoperative management has also been utilized in older, less-active patients.

Impact of shoulder, elbow and forearm position on biceps tendon excursion: A cadaveric study

PURPOSE

This experimental study investigated the long head biceps tendon (LHBT) excursion that occurs at various positions of the upper limb during tendon stabilizing procedures. We hypothesized that shoulder abduction, elbow extension and forearm pronation would maximize the excursion of the LHBT and potential impacts on tendon stabilization.

MATERIALS & METHODS

Forequarter specimens from 12 fresh frozen cadavers were used in this study. The study was performed at 0° and 30° of shoulder abduction. Elbow position was either 90° of flexion or full extension with the forearm either in full pronation or supination. A total of 14 combinations of positions were studied. A load of 55 N was applied to the distal biceps. The excursion of the proximal part of LHBT was measured for each of the different positions.

RESULTS

At a shoulder position of 30° of flexion, shoulder abduction of 30° created significantly greater excursion than 0° of shoulder abduction (p < 0.001). Both full extension of the elbow and full pronation of the forearm also showed significant excursion of the tendon when compared to supination (p < 0.001).

CONCLUSIONS

The position of the shoulder, elbow and forearm has a significant effect on biceps excursion. Thirty degrees of shoulder abduction and 30° of forward flexion with the elbow in full extension and the forearm in full pronation maximizes excursion.

CLINICAL RELEVANCE

Information about the excursion of the LHBT affected by the position of the upper limb is useful for any biceps tendon stabilizing procedure. During an operation, the position of the upper limb should be monitored in order to maintain a proper anatomic length-tension relationship.
