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)
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)
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)
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)
in 57 % of the ankles by palpation. BMI was the only independently influential factor in the identification of the superficial peroneal nerve. Conclusion Since in nearly six out of the ten ankles the superficial peroneal nerve can be identified, it is advised to assess its anatomy prior to portal placement. A higher BMI negatively influences the(More)
We report a 13-year-old soccer player with osteonecrosis of the talus and a large carticular fragment. The defect was revitalized with curettage and drilling and filled with autologous bone graft followed by the fixation of the carticular fragment with two conventional lag screws. Screw placement was such that they could be removed arthroscopically. Healing(More)
We present a 3-portal approach for arthroscopic subtalar arthrodesis with the patient in the prone position. The prone position allows the use of the two standard posterior portals and it allows for accurate control of hindfoot alignment during surgery. Furthermore, the introduction of talocalcaneal lag screws is easy with the patient in this position. In(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)
PURPOSE The presented study was performed to evaluate the midterm clinical and radiological results and complication rates of the first 40 patients with an ankle fusion through a posterior arthroscopic approach. METHODS Forty consecutive patients with end-stage post-traumatic ankle osteoarthritis were treated with posterior arthroscopic ankle fusion. All(More)
