Distal Phalanx Depth Variation and Implications for Zone I Flexor Tendon Anchor Repairs: A CT and X-Ray Comparative Study
Digital radiographs provide sufficiently accurate measurements for most clinical scenarios with the use of a modest safety margin. Distal phalanx size varies by digit and gender, warranting added caution in female patients and in ring and little fingers. Our findings support routine consideration of retrograde oblique drilling techniques to optimize bone purchase and reduce the risk of dorsal cortex penetration.
