Dorsal metacarpal flaps.

M J Earley, R H Milner

    British Journal of Plastic Surgery
    |July 1, 1987

    Summary
    This summary is machine-generated.

    This study details the anatomical basis of dorsal metacarpal flaps, finding high prevalence of the fascial artery in dissections. Clinical utility of Doppler studies was limited, but flap use in two patients is discussed.

    Area of Science:

    • Anatomy
    • Vascular Surgery
    • Hand Surgery

    Background:

    • The history and anatomical underpinnings of dorsal metacarpal flaps are explored.
    • Understanding the vascular supply is crucial for flap viability and surgical planning.

    Observation:

    • Thirty hand dissections revealed the fascial variant of the first dorsal metacarpal artery in 90% and the second in 97%.
    • The origin, course, branching patterns, and termination of these arteries were meticulously illustrated.
    • Doppler ultrasonic flowmeter studies in 52 hands were conducted but yielded limited clinical utility.

    Findings:

    • The dorsal metacarpal arteries, particularly the second, demonstrate consistent anatomical presence, supporting their use in flap construction.
    • While Doppler studies were unhelpful, the anatomical dissections provide a robust basis for flap design.

    Implications:

    • This research provides essential anatomical data for plastic and reconstructive surgeons utilizing dorsal metacarpal flaps.
    • The findings can help anticipate and mitigate potential difficulties in flap elevation and inset.
    • Further investigation into alternative methods for pre-operative vascular assessment may be warranted.
