Abstract
The development of good quality small-diametered arthroscopes and refined arthroscopic techniques has contributed to the improvement of the subtalar arthroscopy. The therapeutic indications are synovectomy, removal of loose bodies, debridement and drilling of osteochondritis dissecans, excision of subtalar impingement lesions and osteophytes, lysis of adhesions for post-traumatic arthrofibrosis, removal of a symptomatic os trigonum, calcaneal fracture assessment and reduction, and arthroscopic arthrodesis of the subtalar joint. The subtalar arthroscopy can be done in supine position using thigh holder or in lateral decubitus position. The arthroscope generally used is a 2.7-mm 30 degrees short arthroscope. Noninvasive distraction with a strap around the hindfoot can be helpful. Usually anterolateral, middle and posterolateral portals are utilized for inspection and instrumentation within the joint. Twoportal posterior subtalar arthroscopy in prone position can be performed as well with 4.0-mm 30 degrees arthroscope, depending on the type and location of the subtalar pathology. The subtalar arthroscopy is a technically demanding procedure, which requires proper instrumentation and careful operative technique. Possible complications are nerve damage and persistent wound drainage.
