A new posterior triceps approach for total elbow arthroplasty in patients with osteoarthritis secondary to fracture: preliminary clinical experience.
Journal of Shoulder and Elbow Surgery 2016 August
BACKGROUND: During the past decade, total elbow arthroplasty (TEA) procedures have increased because of an increase in the number of trauma patients. Even though most current posterior approaches to the elbow provide excellent joint exposure, they involve the risk of extensor mechanism injury and of eventual insufficiency, particularly in patients with osteoarthritis (OA) secondary to fracture. I describe a new triceps exposure approach for TEA, the anconeus-triceps lateral flap, which has proved valuable in patients with distal humeral and olecranon fracture malunion, and its preliminary results at a minimum follow-up of 24 months.
METHODS: Twenty consecutive patients with OA due to distal humeral and olecranon fracture malunion underwent TEA by the anconeus-triceps lateral flap approach, which preserves the olecranon insertion of the medial portion of the triceps proper tendon.
RESULTS: At a mean follow-up of 33 months, the mean Mayo Elbow Performance Score rose from 41.3 to 94.3. The mean pain score on the visual analog scale fell from 7.1 to 1.1. There were no patients with insufficiency, secondary detachment of the triceps tendon, or grade 4 to 5 of the Medical Research Council scale.
DISCUSSION: These preliminary data suggest that preservation of the insertion of the medial portion of the triceps proper tendon enables earlier active rehabilitation. Moreover, the new approach provides optimum exposure of the olecranon also in patients with OA secondary to intra-articular fracture of the distal humerus and olecranon, where scarring and bone deformity usually hamper joint exposure.
