Massive traumatic articular bone loss of the capitulum humeri treated by costal osteochondral autograft reconstruction: A case report

Introduction: Articular traumatic bone loss is a severe condition with heterogeneous outcomes, often necessitating complex technical solutions and posing challenges in managing both bone and cartilage loss. Thus, some surgeons have used a technique of osteochondral autograft using a rib to fix an articular bone loss to manage both of these tissue losses. Presentation of case: We present the case of a 25-years-old patient, who had a complex open elbow injury. He presented an association of a terrible triad of the elbow injury with an open traumatic bone loss of the capitulum humeri and unfixable lesion of the lateral collateral ligament complex of the elbow. We initially managed these lesions with an external fixator for 2 months followed by a reconstruction of the capitulum humeri using a costal osteochondral autograft. Unfortunately, the patient was lost to follow-up after the 1 month post-operative consultation but he had some encouraging results. Discussion: In this case report, we describe our technique using an osteochondral autograft to address complex bone and cartilaginous losses, thereby expanding the treatment options available to trauma surgeons. Conclusion: This case report shows that a reconstruction of the capitellum humeri for a traumatic bone loss with an osteochondral autograft using the eighth rib can be easily performed. More generally, this technique could even help to manage complex traumatic substance loss of both bone and cartilage in other locations.
