Abstract

Radiocapitellar pathology after traumatic injury to the elbow can be challenging to treat. The anconeus interposition arthroplasty has been proposed to treat radiocapitellar or proximal radioulnar joint dysfunction and pain, or both. This study evaluated whether radial head excision (native or prosthetic), followed by an anconeus interposition arthroplasty, relieves pain and improves subjective and objective elbow function in patients with post-traumatic radiocapitellar pathology. A retrospective comparative case series was performed of 50 consecutive patients who underwent a native radial head excision or radial head implant excision, followed by an anconeus interposition arthroplasty. Clinical outcome scores, range of motion, and proximal radius migration were evaluated in patients with at least 2 years of follow-up. Included were 23 patients (11 native and 12 prosthetic radial heads) with a mean age of 41 years. Average follow-up was 38 months. Overall, significant improvement was obtained in the Disabilities of the Arm, Shoulder and Hand and visual analog scale scores. Range of motion significantly improved from preoperatively to postoperatively. Patients with a native radial head excision scored better on the Single Assess...Continue Reading

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
