Anomalous flexor pollicis longus muscle

Y Murakami, K Edashige

    The Hand
    |February 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    An unusual tendon connecting the flexor pollicis longus to the flexor indicis profundus muscle restricted independent thumb flexion. This rare anatomical variation was associated with chronic tenosynovitis.

    Area of Science:

    • Anatomy
    • Orthopedics
    • Hand Surgery

    Background:

    • Anatomical variations in the hand can lead to complex clinical presentations.
    • Understanding the detailed anatomy of flexor tendons is crucial for diagnosing and treating hand dysfunction.

    Observation:

    • A case study detailing an anomalous tendon connecting the flexor pollicis longus (FPL) to the flexor indicis profundus (FIP) was observed.
    • This anatomical anomaly resulted in restricted independent flexion of the thumb.

    Findings:

    • The primary finding is the presence of an aberrant tendon linking the FPL and FIP.
    • The anomaly was directly correlated with the observed limitation in independent thumb flexion.
    • Chronic tenosynovitis was a concurrent condition associated with this anomalous tendon.

    Implications:

    • This case highlights the importance of considering rare anatomical variations in cases of unexplained thumb dysfunction.
    • Accurate diagnosis of such anomalies can guide appropriate surgical or conservative management strategies.
    • Further anatomical studies may reveal the prevalence and clinical significance of this specific FPL-FIP tendon anomaly.
