Understanding the anatomy of the ankle ligaments is important for correct diagnosis and treatment. Ankle ligament injury is the most frequent cause of acute ankle pain. Chronic ankle pain often finds its cause in laxity of one of the ankle ligaments. In this pictorial essay, the ligaments around the ankle are grouped, depending on their anatomic(More)
This review article provides a current concepts overview of osteochondral defects of the talus, with special emphasis on treatment options, their indications and future developments. Osteochondral defects of the talar dome are mostly caused by a traumatic event. They may lead to deep ankle pain on weight-bearing, prolonged swelling, diminished range of(More)
OBJECTIVE To review the literature concerning articles evaluating the delayed operative treatment of isolated syndesmotic instability. MATERIAL AND METHODS The main databases Pubmed/Medline, Cochrane Database of Systematic Reviews, Cochrane Clinical Trial Register, Current Controlled Trials and Embase were searched from 1988 to September 2008 to identify(More)
BACKGROUND The surgical treatment of posterior ankle impingement is associated with a high rate of complications and a substantial time to recover. An endoscopic approach to the posterior ankle (hindfoot endoscopy) may lack these disadvantages. We hypothesized that hindfoot endoscopy causes less morbidity and facilitates a quick recovery compared with open(More)
We have read the article ''Treatment of anterolateral impingements of the ankle joint by arthroscopy'' by A.-H.M. Hassan with interest, care and appreciation [1]. One of the questions in this publication is whether anterior ankle arthroscopy can routinely be performed without joint distraction. He states that in patients with anterior ankle soft tissue(More)
Despite the fact that the superficial peroneal nerve is the only nerve in the human body that can be made visible; iatrogenic damage to this nerve is the most frequently reported complication in anterior ankle arthroscopy. One of the methods to visualize the nerve is combined ankle plantar flexion and inversion. In the majority of cases, the superficial(More)
Debridement and bone marrow stimulation of the subchondral bone is currently considered to be the primary surgical treatment of most osteochondral lesions of the talus. Different methods of bone marrow stimulation are used, including drilling, abrasion, and microfracturing. The latter has gained recent popularity. In this technical note we describe a(More)
Anterior ankle arthroscopy can basically be performed by two different methods; the dorsiflexion- or distraction method. The objective of this study was to determine the size of the anterior working area for both the dorsiflexion and distraction method. The anterior working area is anteriorly limited by the overlying anatomy which includes the neurovascular(More)
Ankle arthroscopy provides the surgeon with a minimally invasive treatment option for a wide variety of indications such as impingement, osteochondral defects, loose bodies, ossicles, synovitis, adhesions, and instability. Posterior ankle pathology can be treated using endoscopic hindfoot portals. These posteromedial and lateral hindfoot portals provide(More)
PURPOSE To study the safety and efficiency of posterior arthroscopic ankle arthrodesis. METHODS Ten fresh-frozen human lower leg specimens without evidence of previous surgery to the foot and ankle were selected. Arthroscopic debridement of the tibiotalar joint was performed in all specimens using a standardized protocol. Anatomical dissections were(More)
