Radioulnar heterotopic ossification is a rare occurrence found in approximately 2% of all forearm injuries. Treatment is complicated by relatively high recurrence rates. Strategies to decrease recurrence have included the range of motion exercises and the interposition of inert or autogenous barriers. We report on the interposition of human acellular dermal matrix (ADM) for the treatment of distal radioulnar synostosis. We report a novel technique for the treatment of distal radioulnar heterotopic ossification. After resection, ADM in a cigar-shaped construct is interposed between the radius and ulna. Patients are followed clinically and radiographically. Two female patients were treated. Both patients had significant improvement in the range of motion in supination and pronation of the affected wrist postoperatively with an average follow-up of 36 months. There were no postoperative complications. Neither patient had recurrent disease. We describe the successful treatment of 2 patients with distal radioulnar heterotopic ossification with the use of human ADM. The ADM provides a barrier between the radius and ulna to prevent the recurrent formation of heterotopic ossification. ADM usage results in no donor site morbidity and is theoretically more resistant to infection when compared with nonbiologic barriers such as silicone and Integra. This technique is a simple, safe, and effective way to treat and prevent the recurrence of radioulnar heterotopic ossification.

Background

Limited data exist on plastic surgery practices in Sub-Saharan Africa. The aim of this study was to characterize the spectrum of disease and operative procedures at a teaching hospital in Maputo, Mozambique to help understand the challenges of providing care for the local providers and to provide contextual relevance for training through partnerships.

Methods

A mixed-methods approach was utilized to perform an ongoing needs assessment. A retrospective review was performed of plastic surgery operative records, ward admissions records, and death records in a tertiary-care hospital in Maputo, Mozambique for the period January 2015 to December 2015.

Results

Limited resources (equipment, block-time, personnel, and perioperative services) were observed. The most common diagnoses for the 455 patients evaluated were burns (44%) and neoplasms (17%). Congenital abnormalities accounted for only 1% of the patient diagnoses. Of the 408 procedures performed, the majority were skin grafts (43%) and skin excisions (31%). Sepsis from burns accounted for 70% of documented deaths (14/20). The mean number of days to skin grafting for inpatients was 53 days.

Conclusion

We observed a large burden of burns and skin graft procedures at a public referral teaching hospital in Mozambique. Our findings provide contextual relevance to help focus public health efforts and improve plastic surgery training and practices.
