Intralesional surgery is most commonly used for aneurysmal bone cysts. Rarely is en bloc resection used for active, aggressive, recurrent lesions and those located in expendable bones. However, persistence or recurrence of aneurysmal bone cysts is common. The clinical behavior of aneurysmal bone cysts is more aggressive in younger patients. Selective embolization is used as the primary treatmen...

Acetabular intraosseous cysts are frequently encountered in patients with dysplasia or femoroacetabular impingement. Small cysts are typically addressed by removing the cyst lining and stimulating healing via microfracture or abrasion chondroplasty. In contrast, larger cysts involving 1-3 cm(3) frequently require additional fortification with bone graft material to facilitate osseous ingrowth a...

BACKGROUND Simple or unicameral bone cysts are common benign fluid-filled lesions usually located at the long bones of children before skeletal maturity. METHODS We performed demineralized bone matrix and iliac crest bone marrow injection combined with elastic intramedullary nailing for the treatment of simple bone cysts in long bones of 9 children with a mean age of 12.6 years (range, 4 to 1...

INTRODUCTION Surgical management of large talar dome cysts is challenging due to increased morbidity by associated cartilage damage and malleolar osteotomy. The purpose of this study is to evaluate the clinical and radiological outcome of endoscopic curettage and bone graft for large talar dome cysts. METHODS This is a retrospective analysis of data for eight patients (eight feet) who were tr...

Synovial or ganglion cysts are uncommon lesions that may occur within the spinal canal. Over 50 reported cases have demonstrated a preponderant incidence at the L4-L5 level in association with degenerative hypertrophic facet changes ( 1, 2). The typical computed tomography (CT) appearance is that of an epidural lowdensity lesion adjacent to the degenerated facet joint that may or may not have a...

bacilli from the joint aspirates rule out a tuberculous arthritis. The clinical picture is consistent with rheumatoid arthritis, although the Rose-Waaler test is only weakly positive. The continued pain and elevated ESR suggest that there is persistent inflammatory or destructive activity in the joints. Radiological deterioration in the joints has been associated with an increase in the number ...

We reviewed 32 children after the treatment of simple bone cysts by intralesional injections of methylprednisolone acetate. The age of the child and the activity and size of the cyst did not significantly affect the radiological outcome. The earliest time at which the radiological response could be reliably determined was three months. After a median period of review of five years, four (13%) c...

Rounded areas of translucency in the bones forming an osteoarthritic joint are well known to radiologists and to orthopaedic surgeons. They are not given much prominence in pathological accounts : their formation is vaguely ascribed to degeneration in the bone in keeping with the degeneration in the neighbouring cartilage. Their frequency was given by Plewes (1940), from clinical and radiologic...
