PURPOSE: This study aimed to evaluate the clinical outcome and graft survival following coronoid reconstruction with osteochondral bone grafts for post-traumatic coronoid deficiency treatment. We hypothesized that coronoid reconstruction using an osteochondral bone graft will provide favorable results in treating post-traumatic coronoid deficiency.
METHODS: A retrospective review was performed on eight patients (mean age = 45.8 years) who underwent osteochondral bone graft reconstruction indicated for post-traumatic coronoid deficiency. The osteochondral bone grafts were obtained from the radial head remnant (four patients), olecranon tip (two patients), and iliac crest (two patients). All the injuries were terrible triad. The mean duration from injury to surgery was 79.3 weeks. The visual analog scale (VAS) for pain, motion arc, and Mayo elbow performance score (MEPS) were used to evaluate the clinical outcome. Radiologic evaluation of graft healing and integrity was performed using computed tomography at 19 months and plain elbow radiography at 24.1 months after reconstruction. The immediate graft height was measured.
RESULTS: VAS and MEPS values improved from 4.1 ± 1.2 to 1.1 ± 0.3 and 34.2 ± 16.9 to 85.0 ± 7.1, respectively (p = 0.018, p = 0.018) after reconstruction. The motion arc significantly improved from 84.2° ± 16.1° to 102.1° ± 18.2° at the final follow-up of 39.1 ± 18.8 months (p = 0.048). All the osteochondral grafts survived, with nonunion in two patients (25%). The mean immediate graft height was 15.4 ± 2.6 mm. Among the eight patients, three (37.5%) developed secondary osteoarthritis of the ulnohumeral joint.
CONCLUSIONS: Coronoid reconstruction with osteochondral bone graft may serve as an option to salvage post-traumatic coronoid deficiency. Sufficient graft height was required for graft survival. Secondary osteoarthritis of the ulnohumeral joint should not be underestimated during follow-up.
