Abstract
Background: Aneurysmal bone cysts (ABCs), were first described by Drs. Jaffe and Lichenstein in 1942 when they described pelvic and spine lesions that when exposing the lesion and opening in to its thin wall, the surgeon was immediately confronted by a large hole containing much fluid blood.
Aim of the Work: To describe the efficacy of new line treatment modalities of (Aneurysmal Bone Cysts) compared to conventional lines of management regarding the:
Long term outcomes and healing rate.
Recurrence rates.
Complications after therapy.
Patients and Methods: Criteria for considering studies for this review:
Types of the studies: published observational analytical studies (case-control_ case-series _ RCT or cohort studies) which studied the efficiency of new lines in the management of aneurysmal bone cyst.
Types of participants: participants were children and young age (below the age of 50 yrs) with a diagnosis of aneurysmal bone cyst.
Types of interventions: drugs like (Bisphosphonate or denosumab) were administered for a time determined by the case improvement, or minimally invasive techniques like (cryosurgery or curopsy) was done.
Results: Through the results of our study that compared between these recent modalities according to healing, recurrence, and complications rate; we are able to say that recent strategies have a high rate of healing ranges from 78.57% with bisphosphonate to 100% with doxycycline and cryotherapy.
Conclusion: There are recent evolving trends in the management of ABC other than the classic ways of management, they are less invasive, have less recurrence rate reaches to 0 % like with bisphosphonate, less complications rate as well reaches to 0 % like with doxycycline and bisphosphonate, high healing rate reaches to 100 % like with doxycycline and taking in consideration how to handle cases of ABC that classic way of management can’t handle like spinal ABC.
