Albers-Schönberg disease

Albers-Schönberg disease, also known as adult autosomal dominant osteopetrosis or marble bone disease, is a hereditary disorder characterised by increased bone density throughout the skeleton. Although the bones appear markedly dense on imaging, their structure is abnormal, and they may be brittle, leading to fractures, bone pain, and complications related to the excessive bone mass. Early recognition and management of complications are important to preserve … Continue reading Albers-Schönberg disease

Ainhum

Ainhum is a rare condition marked by the development of a constricting fibrous band around a digit, most commonly the base of the fifth toe. Over time this band tightens, leading to progressive swelling of the part distal to it, loss of bone support and eventually the spontaneous detachment (auto-amputation) of the digit. Because the condition often advances unnoticed until significant tissue loss or deformity … Continue reading Ainhum

Adhesive Arachnoiditis

Adhesive arachnoiditis is a severe and chronic condition in which inflammation of the arachnoid membrane (one of the protective layers around the spinal cord and nerve roots) leads to scar formation, nerve root clumping, disrupted cerebrospinal fluid flow and potentially progressive neurological dysfunction. The condition may arise after surgery, trauma, infection, chemical irritation or other insults to the intrathecal space. Because the nerve roots may … Continue reading Adhesive Arachnoiditis

Adductor Tendinopathy

Adductor tendinopathy is a disorder of the tendons of the adductor muscle group of the inner thigh. The adductor muscles are responsible for bringing the legs toward the midline and stabilising the pelvis during movement. When the tendons that attach these muscles to the bone become overloaded, irritated or degenerate, the condition known as adductor tendinopathy may develop. Because the adductor group plays a key … Continue reading Adductor Tendinopathy

Adamantinoma

Adamantinoma is a rare bone tumor that arises most often in the lower limbs, especially the tibia. It is generally slow growing and of low malignant potential, but it can be locally aggressive and has risk of recurrence or metastasis under certain circumstances. Because an adamantinoma may infiltrate bone cortex and medullary cavity, careful diagnosis and surgical planning are critical to preserving limb function. Histology … Continue reading Adamantinoma
