Triceps Tendinopathy

Cell-based therapy of the elbow: evidence for lateral tendinopathy-a review on current treatments

PURPOSE

Cell-based therapies are on the rise in treating intra and extraarticular pathologies, trying to avoid surgical intervention and support local repair processes. Therefore, the aim was to summarize current evidence-based treatment options for a cell-based therapy around the elbow.

METHODS

Through a literature review up-to date treatment algorithms and therapies have been identified and have been rated according to their evidence level for clinical recommendation.

RESULTS

Regarding the four extraarticular anatomical regions of the elbow (anterior, medial, posterior and lateral) and the joint itself, the lateral elbow and its´ tendinopathies as well as the use of cell-based treatment options have been extensively studied and, therefore, allow for clear and evidence-based recommendations. The remaining three regions as wells as the intraarticular application do not show enough evidence for a clinical recommendation.

CONCLUSION

In conclusion the cell-based approach for treating elbow pathologies can only be recommended for the lateral elbow, as there has been shown sufficient evidence for the extraarticular application. It has to be mentioned, that the results from the lateral elbow maybe transferred to other extra-articular tendinopathies, as the lack of evidence may be due to the rare appearance of posterior, medial and anterior tendon affection. No recommendation can be given for intra-articular use.

Biceps, Brachialis, and Triceps

Tendon injuries at the elbow affect mostly the distal biceps and can progressively degenerate over time or rupture in an acute event. The degree of retraction may depend on the integrity of the lacertus fibrosus, a fibrous expansion that merges with the forearm flexor fascia. Biceps disorders are frequently associated with fluid or synovitis of the adjacent bicipital bursa; primary bursal disorders (primary inflammatory synovitis) can also be observed. Distal triceps is less frequently injured than the distal biceps, and tears usually manifest as distal ruptures with avulsion of a small flake of bone from the tip of the olecranon. Brachialis injuries are uncommon and the consequence of sudden muscle stretching during forced elbow hyperextension, as in posterior elbow luxation.
