Posterior Endoscopic Cervical Decompression: Review and Technical Note.

ABSTRACT: Endoscopic spine surgery for the treatment of degenerative spinal diseases from lumbar to cervical spine has accelerated over the past 2 decades. Posterior endoscopic cervical discectomy (PECD) has been described as a safe, effective, and minimally invasive procedure for cervical radiculopathy or even part of the myelopathy. This procedure also has been validated with comparable outcomes to open and microscopic surgery. Radiculopathy due to foraminal disc herniation or foraminal stenosis should be the optimum indications of this procedure. Intraoperative 3-dimensional navigation can help surgeons to get quick and great quality guidance for endoscopic surgeons. In this review, we will focus on the technical details and evidence-based results of PECD which is a promising procedure for cervical radiculopathy with the advantages of a minimally invasive method.

Project description:Accurate positioning of the total ankle arthroplasty implant components with the absence of any hindfoot deformity does not preclude the development of bony impingement. In cases of ankle stiffness after total ankle arthroplasty, the usual limitation is in dorsiflexion. If triceps surae contracture is excluded or persistent restriction remains in ankle dorsiflexion after gastrocnemius recession or tendo-Achilles lengthening, posterior ankle capsulectomy, debridement of posterior ankle gutter, and release of the deep posterior deltoid ligament and the posterior talofibular ligament are indicated. In this Technical Note, the technical details of endoscopic posterior ankle decompression and release after total ankle arthroplasty are described. Technique Video Video 1 Endoscopic posterior ankle decompression and release after total ankle arthroplasty of the left ankle. The patient is in the prone position. Posteromedial portal is the viewing portal and posterolateral portal is the working portal. The flexor hallucis longus (FHL) tendon is exposed. The arthroscope is switched to the posterolateral portal and the posterolateral ankle capsule is resected with arthroscopic instruments via the posteromedial portal. The FHL tendon is pushed medially by the instruments to facilitate resection of the more medial posterior ankle capsule. The arthroscope is switched back to the posteromedial portal and the most lateral part of the posterior ankle capsule is resected with arthroscopic shaver and radiofrequency wand via the posterolateral portal. Then, the FHL tendon is looped with a vascular sling via the posterolateral portal and the tendon is retracted laterally. The medial part of the posterior ankle capsule is resected with arthroscopic instruments via the posteromedial portal. The fibrous tissue of the posteromedial ankle gutter is also resected. The arthroscope is switched to the posteromedial portal and the fibrous tissue of the posterolateral ankle gutter is resected. The scarred posterolateral ankle ligamentous structure and fibrous band is released from its calcaneal insertion. The arthroscope is switched back to the posterolateral portal and the scarred posteromedial ankle ligamentous structure and fibrous band is carefully cut by a No. 15 scalpel with the cutting blade facing laterally.
