Q

Trigger finger definition?

A

Common condition associated with abnormal flexion of the digits. It is thought to be caused by a disparity between the size of the tendon and pulleys through which they pass. In simple terms the tendon becomes ‘stuck’ and cannot pass smoothly through the pulley.

  2. 40-90 y/o
  3. International data
  4. Factors = age, sex, weight, height, previous fracture, parental fracture, current smoking, glucocorticoids, rheumatoid arthritis, secondary osteoporosis, alcohol intake
  5. Bone mineral density (BMD) is optional, but clearly improves the accuracy of the results. NICE recommend arranging a DEXA scan if FRAX (without BMD) shows an intermediate result
