• Bone Disorder

  Differentiating Aneurysmal Bone Cyst from Other Diseases Aneurysmal bone cyst must be differentiated from following bone disorders: Epidemiology and Demographics ABC accounts for 1% to 2% of all primary bone tumors. [13] The incidence of aneurysmal bone [wikidoc.org]

It is therefore an integral part of the diagnostic workup when dealing with (myo)fibroblastic lesions of soft tissue and bone. Two cases of myositis ossificans with USP6 rearrangement were published so far. [ncbi.nlm.nih.gov]

Blood chemistry and metabolic workup are benign. [doi.org]

Depending on the choice of treatment, a positive response occurs in 20 to 80 % of cases. These rates are unacceptable, particularly considering they concern the treatment of benign lesions affecting children. [ncbi.nlm.nih.gov]

It is mandatory to distinguish ABC from UBC, as prognosis and treatment are different. UBCs resolve spontaneously between adolescence and adulthood; the main concern is the risk of pathologic fracture. [ncbi.nlm.nih.gov]

Often several years of active vigilance is necessary What is the Prognosis of Simple Bone Cyst? (Outcomes/Resolutions) The prognosis of a Simple Bone Cyst is usually excellent with accurate diagnosis and appropriate treatment. [dovemed.com]

Curettage and bone grafting, nailing, injection of bone marrow or cryotherapy to prevent pathologic fracture Methylprednisolone injections have been used to promote healing Complications Pathologic fractures in 50-65% Growth arrest in affected limb Prognosis [learningradiology.com]

Treatment and prognosis Intervention is usually not required for an asymptomatic lesion. If large and threatening to fracture, or causing deformity then an intralesional steroid injection can be performed 3, 4, 5. [radiopaedia.org]

BACKGROUND: Jaw pseudocysts are benign osseous lesions of unclear etiology. Among these, the simple bone cyst (SBC) and aneurysmal bone cyst (ABC) are intriguing bone pathologies still rarely studied together. [ncbi.nlm.nih.gov]

These results may suggest that venous obstruction of the lesions play an important role in the etiology of multiple simple cysts, as shown in typical bone cysts. [link.springer.com]

Epidemiology: UBCs account for 3% of all bone tumors. They commonly occur in patients age 4-10 years old (Herring, 2014). Males are twice as likely to have a UBC as females. [posna.org]

This new hypothesis for SBC formation in non-load-bearing region for knee, which cannot be explained by the existing theories, will provide us a new angle to understand the pathomechanism and pathophysiology of subchondral bone disturbance in osteoarthritis [ncbi.nlm.nih.gov]

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test Aneurysmal bone cyst (ABC) is a multicystic and expansile bone tumor of uncertain line of differentiation. [mayomedicallaboratories.com]

The true pathophysiology of ABCs is unknown. [13] Different theories about several vascular malformations exist; these include arteriovenous fistulas and venous blockage. [emedicine.medscape.com]

The true etiology and pathophysiology remain a mystery, but the mainstay of treatment has been intralesional curettage. Recurrence is not uncommon. [dx.doi.org]

To prevent increasing bone deformity and fragility, the deformity should be corrected as quickly as possible using intramedullary nailing or other fixation techniques. [ncbi.nlm.nih.gov]

The surgical treatment measures for Simple Bone Cyst may include the following: Aspiration of the fluid Injection of steroids into the cavity: Steroids help in prevention of re-accumulation of the cyst fluid; it also assists in filling-up of the cyst [dovemed.com]

In addition to identifying the cause of these cysts, research is also being done to better understand what might be done to prevent them. Research is also looking at better agents to inject into the cysts to prevent them from coming back. [orthoinfo.aaos.org]
