Unicameral bone cysts treated by injection of bone marrow or methylprednisolone

Abstract

In 79 consecutive patients with unicameral bone cysts we compared the results of aspiration and injection of bone marrow with those of aspiration and injection of steroid. All were treated by the same protocol. The only difference was the substance injected into the cysts. The mean radiological follow-up to detect activity in the cyst was 44 months (12 to 108). Of the 79 patients, 14 received a total of 27 injections of bone marrow and 65 a total of 99 injections of steroid. Repeated injections were required in 57% of patients after bone marrow had been used and in 49% after steroid. No complications were noted in either group. In this series no advantage could be shown for the use of autogenous injection of bone marrow compared with injection of steroid in the management of unicameral bone cysts.

Autologous Osteochondral Grafting (Mosaic Arthroplasty) for Treatment of Subchondral Cystic Lesions in the Equine Stifle and Fetlock Joints

“…Surgical debridement and corticosteroids resulted in a 64% return to soundness in horses 1–3 years old but poor results (16% recovery) in older horses 17 . This is consistent with the variable response of unicameral bone cysts in children after intralesional corticosteroids 18,19 …”

Aqueous calcium sulphate as bone graft for voids following open curettage of bone tumours

“…Classification of radiological results (Chang et al .) . CR, cyst filled by formation of new bone with or without small static, radiolucent area(s) less than 1 cm; LR, local recurrence; NR, static, radiolucent area same size as pretreatment; PR, static, radiolucent areas less than 50% of the original cyst.…”

“…In addition, at the 1‐year review, patients were scored according the Toronto Extremity Salvage Score (TESS) . The radiographs were reviewed and the results reported using the system described by Chang et al . The classification of Chang et al .…”

Injectable Form of Calcium Sulphate as Treatment of Aneurysmal Bone Cysts

“…The results of this treatment have been variable and usually require multiple injections 5,6 . Alternative percutaneous procedures seek to retain the low morbidity but improve bone reconstruction with reproducibly successful results 7–10 . One of these alternative reconstructive options is the use of calcium products.…”
