Question

Preventing bowstringing of tendons that transverse more than one joint:

Answer 1

Answer:

The suitable words for given fill in the blanks will be -

A. volar wrist flexion.

B. wrist flexion.

C. finger flexion.

Explanation:

Preventing bowstringing of tendons that transverse more than one joint:

A. The flexor retinaculum prevents bowstringing of the tendons of FDS, FDP, FPL during - volar wrist flexion

B. The extensor retinaculum prevents bowstringing of the tendons of APL, EPB, EPL, EI, EDC, EDM during - wrist flexion

C. The A1-5 and C1-3 pulleys prevent bowstringing of the tendons of FDS and FDP during- finger flexion.

• Bowstringing is a complication causes mainly by loss of proximal pulleys, mainly triggered by finger. The flexion arm is increased when flexor tendon moves away from the metacarpophalangeal joint.
