Weaver bottom is associated with?

• A. Subgluteal infective bursitis with direct extension of the ischium
• B. Calcaneal spurs
• C. Trochanteric bursitis
• D. Ischiopubic synchondrosis

Answer: (A)

Weaver's bottom is the name given to inflammation of the ischiogluteal bursa, the small fluid-filled sac between the ischial tuberosity and the gluteus maximus. Prolonged sitting on a hard surface irritates this bursa, producing buttock pain that worsens with sitting and can cause swelling. When the bursitis is infectious, the infection can spread from the bursa to the nearby bone, the ischium, leading to subgluteal infective bursitis with direct extension to the ischium. This is why the best description is subgluteal infective bursitis with extension to the ischium. The other options refer to different structures or conditions: calcaneal spurs affect the heel, trochanteric bursitis involves the lateral hip bursa, and ischiopubic synchondrosis is a growth-area joint in children, none of which define Weaver's bottom.
