Avascular Necrosis of the Hamate [PDF]

Journal of Hand Surgery, 1994
Avascular necrosis of the hamate is a rare condition, only one case having been reported in the literature (Van Demark and Parke, 1992). This reflects the relative rarity of fractures of the body of the hamate and the arrangement of the intraosseous vascular anatomy. A case is presented, which was diagnosed by MR Imaging and treated surgically.

Pathophysiology of Avascular Necrosis

Hand Clinics, 2022
Avascular necrosis is a complicated, multifactorial disease with potentially devastating consequences. Although the underlying root cause is a lack of appropriate vascular perfusion to affected bone, there are often varying patient-specific, anatomic-specific, and injury-specific predispositions.

Avascular Necrosis of the Glenoid

The Journal of Trauma: Injury, Infection, and Critical Care, 1984
A rare case of avascular necrosis of the glenoid is presented. This process should be considered in the differential diagnosis of shoulder pain and radiologic lesions of the glenoid. In this patient anti-inflammatory medications and exercise resulted in resolution of the symptoms. A good prognosis is expected in this non weight bearing joint.

Avascular Necrosis of the Capitate

Orthopedics, 2010
Although a large portion of the capitate is supplied by a single nutrient vessel, avascular necrosis of the capitatum is a rare condition. Its etiology is not clear, but a number of factors are linked to its pathogenesis including: repetitive trauma, dorsal instability of the carpus, Gaucher disease, systemic lupus erythematosus, gout, and steroid use.

Avascular necrosis of the talus

Orthopedic Clinics of North America, 2004
Avascular necrosis (AVN) of the talus has always been a surgical challenge because the talus is hidden by its anatomic location and has a precarious blood supply. Most cases (75%) of talar AVN are traumatically induced in association with talar body and talar neck fractures.AVN of the talus can be a significant problem because collapse of the talar ...

Avascular necrosis not Charcot's

Diabetic Medicine, 2001
AbstractBackground  A case of avascular necrosis (AN) of the navicular bone, in a 24‐year‐old woman with Type 1 diabetes with peripheral neuropathy, in the absence of any history of direct trauma is presented. The clinical and radiological features at presentation suggested an evolving Charcot arthropathy (CA), but subsequent serial X‐rays clearly ...

Avascular Necrosis of the Talus

Clinical Nuclear Medicine, 2003
Persistent pain in the ankle after relatively minor trauma is common and usually resolves spontaneously. Two cases of persistent pain after minor trauma are presented that involved unusual characteristics of scintigraphic and magnetic resonance imaging, compatible with avascular necrosis of the talar body.

Avascular necrosis in HIV

Rheumatology International, 2011
Avascular necrosis (AVN) is an emerging complication of HIV infection. The incidence of AVN in HIV patients is greater than the general population. Although the incidence has increased in the HAART era, the aetiology remains unclear. We report our experience of AVN from our tertiary referral HIV centre and evaluate risk factors for its development ...
