Surgical clavicle reconstruction after aneurysmal bone cyst resection in a child: A simple method

Abstract

Bone tumors of the clavicle are exceedingly rare with a reported frequency of less than 1% of all bone tumors. [1] Because of this, most doctors have limited experience in the diagnosis and treatment of these tumors. The prevalence of aneurysmal bone cyst (ABC) is greater in the first two decades of life, due to its relationship with the immature and growing skeleton, affecting almost twice as many males as females. [2] It is often found in long bones, particularly in the metaphyseal area of the femur and tibia. It can also be located in the spine and pelvis, [3] but its location in the clavicle is very rare. [4] Differential diagnosis should be considered with essential bone cyst, giant cell tumor, osteoblastoma, chondromyxoid fibroma, and telangiectatic osteosarcoma. [4,5] In this article, we propose a description of a simple technique, some considerations about treatment options in selected ABC located in clavicle during childhood, and a follow-up of more than two years. [6] CASE REPORT A seven-year-old boy was referred to our clinic due to a painful tumor of progressive growth, in the lateral-The clavicle is an infrequent location for primary tumors in general, and aneurysmal bone cyst (ABC) of the clavicle is particularly rare. The challenge of the functional and esthetic result in the treatment of these lesions in the pediatric population is high when considering the reconstruction of critical bone defects. In this article, we present the case of a seven-year-old boy with an ABC in the middle third of the clavicle, treated by resection and reconstruction with free autograft of the fibula stabilized by using an intramedullary titanium nail. We offer a description of the used technique, considerations about treatment options in children, and a follow-up of more than two-and-a-half years.

“…Currently, the major materials of bone defect repairment after clavicle resection include autograft bone (rib, fibula) and allograft bone ( Lin et al, 2014 ). Reconstruction with autograft can achieve good integration because of its ideal osteogenic, osteoinductive, and osteoconductive properties ( Rodríguez-Nogué et al, 2020 ). But this method is associate with morbidities of the donor site, trauma and pain.…”
