Shaped graft for aneurysmal bone cyst of upper-limb bones

Abstract

The optimal treatment of aneurysmal bone cyst remains challenging. The aim of this prospective study was to evaluate the results of using bone grafts shaped to the defects caused by aneurysmal bone cysts of upper limb bones. Fifteen patients (12 males and 3 females) with an average age of 12 years (range 6-16 years) were treated for aneurysmal bone cysts of upper limb bones by intralesional resection, argon beam coagulation and shaped bone graft. The grafts were harvested from 14 patients (11 fibulas and 3 iliac bones) and from the mother of one patient (proximal fibula). Osteosynthesis was required to stabilize the graft in four cases. The modified Enneking's scoring system was used for functional evaluation. One patient developed partial recurrence at 6 months and required reoperation. Superficial wound infection was encountered in one patient. Shortening of the humeral segment was seen in two patients (1 and 1.5 cm) but without angular deformity. After a mean follow-up of 45 months (range 24-68 months), the mean functional score was 97.3%. This technique proved to be reliable in obtaining a well reconstructed and growing bone with no or minimal deformity and good function.

Allogenic fibular bone graft reconstruction with complete regeneration of the lateral malleolus after En bloc resection of a distal fibular aneurysmal bone cyst: A case report

“…At 45 months post-op the patients had a mean functional score of 97.3%, concluding that fibular grafts should be considered a reliable technique for reconstruction after resection of ABCs. 9 Abuhassan and Shannak present an additional case report of three patients who underwent en bloc resection of giant aneurysmal bone cysts with non-vascularized fibular graft reconstruction. Three patients were included in their report, a 6 year old male with a giant ABC of the proximal femur, 8 year old male with a giant ABC of third third metatarsal, and a 23 year old male with a giant ABC of the proximal humerus.…”
