Common synovial sheath of flexor tendons (ulnar bursa)
The median nerve and artery have been retracted laterally in the same preparation shown in the previous view. The common synovial tendon sheath of the flexor digitorum sublimis and flexor digitorum profundus muscles has been opened. This sheath is frequently referred to as the ulnar bursa. A communication exists between this sheath and the synovial sheath of the fifth finger. The latter has not been opened.
