A connecting band of tissue, such as that attaching a flexor tendon to the bone of a finger or toe.‘It flexes the other three digits because it is attached to the flexor digitorum longus tendon by a vinculum along the distal portion of the tarsometatarsus.’
- ‘The most distinctive traits of broadbills are their foot tendons (the flexor hallueis and the flexor profundus tendons are joined by a vinculum band).’
- ‘The vinculum tendon emerges from the distal end of the humerus and follows the posterior margin of the wing, attaching at the distal end of digit 2.’
- ‘In type 2 injuries, the tendon retracts to the PIP level leaving the long vincula intact and preserving a portion of the nutritional blood supply from the sheath.’
- ‘This supply comes through a series of transverse vincula, which function as passageways for blood vessels to reach the tendon.’
A horizontal line drawn over a group of terms in a mathematical expression to indicate that they are to be operated on as a single entity by the preceding or following operator.
- ‘For notational convenience the negative digits are usually written with a vinculum, or overbar, instead of a prefixed minus sign.’
Mid 17th century (in the sense ‘bond, tie’): from Latin, literally ‘bond’, from vincire ‘bind’. The term has been used in anatomy since the mid 19th century.
