Web space (thumb)
The thumb web space, unlike the palmar web spaces, is not bounded by transverse ligaments. This permits greater mobility.
Relations:
- palmar and dorsal surfaces: skin superficial to deep fascia overlying muscles
- proximal: junction of transverse head of adductor pollicis and first dorsal interosseous muscle
- distal: margin of web skin
- ulnarly: first dorsal interosseous muscle, radialis indicis artery
- radial: adductor pollicis, princeps pollicis artery
The thumb web space is filled with fibrofatty material.
