Complications after cosmetic limb lengthening, a specialized center experience.

Background: Cosmetic limb lengthening has been rapidly growing ever since the advent of the external fixators magnetic lengthening nails. Similar to all surgical procedures, cosmetic limb lengthening is not risk free. This paper presents a series of complications encountered and treated at a specialized limb lengthening and deformity correction center, along with an analysis of potential risk factors.

Methods: A series of referred patients for complications after limb lengthening using IM nails were identified. Collected variables included demographics, place of index surgery, complication, and treatment of choice and outcome of treatment.

Results: 22 limb lengthening procedures were identified. Most of these cases were done outside of the U.S. Hardware failure occurred in 23 % of index surgeries, primarily affecting femurs. Mal/nonunion rates were high (45 %), with femurs most affected. Iatrogenic deformities, primarily tibial, and soft tissue complications including contractures and nerve entrapment were observed. Treatment strategies included hardware exchange, bone grafting, and soft tissue release. All patients were successfully treated without any patients suffering from serious long term irreversible outcomes.

Conclusion: This study examines the surgical management of complications arising from cosmetic limb lengthening procedures at a single institution. We provide insights into effective treatment strategies and highlight the risks associated with medical tourism for these procedures. Our findings demonstrate a rising incidence of complications linked to international limb lengthening centers.
