The aim of this study was to describe and to validate an
ultrasound-guided peroneal tendon sheath (PTS) injection technique and to compare
the accuracy of ultrasound-guided vs. palpation-guided PTS injections in a
cadaveric model. DESIGN: Twenty cadaveric lower limbs were injected with and
without ultrasound guidance, using a different color of liquid latex for each
injection technique. The injections were performed by a single investigator in a
randomized order. Cadaveric specimens were dissected 1 wk later by a blinded
investigator who graded injection accuracy on a 3-point scale (1, accurate; 2,
partially accurate; 3, inaccurate). RESULTS: Ultrasound-guided injections were
100% (20 of 20) accurate whereas palpation-guided injections were 60% (12 of 20)
accurate (P = 0.008). Six palpation-guided injections were partially accurate,
and two were inaccurate. Two of the partially accurate and both of the inaccurate
injections were intratendinous. CONCLUSIONS: In a cadaveric model,
ultrasound-guided PTS injections are significantly more accurate than
palpation-guided injections. When performing PTS injections, clinicians should
consider ultrasound guidance to improve injection accuracy and minimize potential
complications such as intratendinous injection.
