Aneurysmal bone cysts are large lytic lesions that appear most often around metaphyseal
bone. The lesions are locally aggressive with high recurrence rates. Therefore, wide
resection is commonly necessary, leading to challenging reconstruction of the defect,
especially when the articular surface is involved. We present a case of an aneurysmal
bone cyst of the fourth metacarpal, treated with an en bloc resection and reconstruction with a metacarpal osteoarticular allograft. At 8 years
after surgery, the patient has shown no signs of recurrence, but radiographic articular
reabsorption was noted. However, the patient showed an excellent outcome with a satisfactory
active range of motion and grip strength. Despite potential complications, osteoarticular
allograft is a feasible alternative when autologous osteoarticular reconstruction
is not an option.
