Peroneal tendoscopy is an innovative technique that allows visualization of the tendons from the myotendinous junction to the peroneal tubercle, together with adjacent anatomic structures such as the recently unveiled vincula. Through a minimally invasive approach, it is possible to diagnose and treat several disorders, such as common tenosynovitis, accessory muscles, hypertrophic bony prominences, and thickened vincula, that can cause pain and tendon catching. Surgical morbidity and postoperative pain are significantly reduced when compared with open procedures. In this paper, the main indications for peroneal tendoscopy are discussed, the available literature is reviewed, and the surgical technique is described. Advantages of this procedure and current limitations are also presented. Anatomic and histological studies were also performed in order to verify: 1) the feasibility of peroneal tendoscopy for evaluation of peroneal tendons, using cadaver specimens; 2) the presence of nervous tissue in cadaver peroneal vincula as well as in tendoscopic vincula biopsies from patients undergoing surgery for chronic lateral ankle pain.

The aim of this work was to evaluate the outcome and efficacy of treatment in a homogeneous group of skeletally immature patients with chronic osteomyelitis of the long bones managed by a combination of radical debridement and insertion of tobramycin-impregnated calcium sulfate pellets to fill the bone defect in a single-stage procedure. Between 2011 and 2016, 12 skeletally immature patients were treated surgically by the reported technique. Single-stage surgery using tobramycin-impregnated calcium sulfate pellets in association with systemic antibiotic therapy yields satisfactory outcomes in skeletally immature children presenting chronic osteomyelitis by reducing the risk of occurrence of comorbidities, hospital stays, and healthcare costs.
