VERDAN /FLEXOR TENDON ZONES : SITE

Question Answer
Flexor Zone IExtends from insertion of the Profundus on the distal phalanx to insertion of the Flexor digitorum superficialis on the middle phalanx
Flexor Zone IIExtends from the proximal portion of the A1 Pulley to insertion of the Superficialis tendon.SIGNIFICANCE -Most problematic region of injury because it contains both the Profundus & Superficialis tendons in a relatively AVASCULAR Region.[NO MAN’S ZONE]
Flexor Zone IIIFrom proximal edge of the A1 pulley to the distal edge of the transverse carpal ligament
Flexor Zone IVLies beneath the Transverse Carpal Ligament
Flexor Zone VProximal to the Transverse carpal ligament & includes the Forearm

Question Answer
Extensor Zone IExtends from distal insertion of the Extensor tendon to the attachment of the central slip at the proximal end of the middle phalanx.
Extensor Zone IIExtends from the metacarpal neck to the proximal inter phalangeal joint
Extensor Zone IIIFrom the metacarpal neck to the distal border of the dorsal carpal ligament
Extensor Zone IVArea under the Dorsal Carpal Ligament (EXTENSOR RETINACULUM )
Extensor Zone VProximal to the proximal margin of Dorsal Carpal Ligament
