Peroneal Tendoscopy: An Innovative Perspective for Peroneal Tendon Pathology
Peroneal tendoscopy is endoscopy of the peroneal tendon sheath. This innovative technique allows for tendon visualization from the myotendinous junction to the peroneal tubercle through a minimally invasive procedure. The entire tendon surface can be explored, and a dynamic evaluation of peroneal tendons can be performed by passive flexion and extension of the ankle to verify correct tendon gliding inside the fibro-osseous tunnel system. Diagnosis and treatment of several disorders that cause pain and tendon catching are possible. These include common tenosynovitis, hypertrophic bony prominences, accessory muscles, partial tears, and thickened vincula. By means of this procedure, the likelihood of postoperative scarring and nerve entrapment is reduced. Surgical morbidity and postoperative pain are significantly lowered when compared to open procedures. The main indications for peroneal tendoscopy are discussed in this movie, and the surgical technique is described. Advantages of this procedure and current limitations also are presented.
