RESUMO
The patella is the largest sesamoid bone in the body and an important structure of the extensor apparatus which is under undue stress during flexion and extension of the knee. Bilateral fracture of the patella without trauma is a very rare event and may be multifactorial without a single cause. A repetitive stress reaction in a previously predisposed bone can be an important cause. We report a case of a 45-year-old female with a nontraumatic bilateral transverse patella fracture with loss of extensor mechanism. A stable surgical fixation for such a displaced fracture with a good rehabilitation program can lead to a good functional outcome.
RESUMO
Takayasu arteritis is a systemic inflammatory disorder that causes harm to the large and medium arteries and their branches. It is primarily prevalent in Asia, Africa, and Latin America, with the incidence rate in Asia being reported to be 100 times higher than in Europe and North America. Females in their second or third decades of life are most commonly affected by this condition. In our case, a 26-year-old male patient was diagnosed with Takayasu arteritis after he experienced a headache and left upper limb weakness. The initial presentation of Takayasu arteritis includes nonspecific constitutional symptoms like fever, malaise, weight loss, and anorexia. Unfortunately, due to the delayed diagnosis of the disease, patients often experience claudication, absence of pulses, hypertension, myocardial infarction, and cerebrovascular accidents. An early and accurate diagnosis of Takayasu arteritis is vital to reduce the economic, social, and psychological burdens associated with the disease.
