Livedoid vasculopathy (LV) is a thrombotic skin disease characterized by episodic painful ulcerations of the distal aspects of the legs. Its healing process typically leaves small porcelain-white scars called atrophie blanche as a result of the occlusion of cutaneous microcirculation. The main goals of the treatment are pain management and the prevention of ulceration and of progressive scarring in the malleolar area. The therapeutic management is still a challenge, however, and most treatments were based on anecdotal off-label protocols...

The disadvantages of the one-third-tubular plate construct to stabilize lateral malleolar fractures include; difficulty achieving adequate cancellous screw thread purchase in the bone of the distal fragment, with subsequent risk of the screws backing out. This can cause irritation and pain, and may require further surgery to remove the screw. We describe a variation of the standard technique that eliminates the risk of the distal lateral malleolar screws backing out and provides a lower profile construct. This has the potential advantages of reduced wound related problems and less postoperative pain and irritation...

BACKGROUND: A concomitant tibial shaft and posterior malleolar fracture is a type of regular compound fracture. The associated posterior malleolar fractures are mostly occult fractures, which often do not show a fracture line on ordinary films, and thus lead to a high rate of misdiagnosis. The aim of the present study was to investigate factors helpful for the pre-operative detection of concomitant posterior ankle fractures using the ipsilateral radiographic tibia and fibula shaft fracture characteristics...

BACKGROUND: Clinically there are different fixation methods used for fixation of the posterior malleolar fractures (PMF), but the best treatment modality is still not clear. Few studies have concentrated on this issue, least of all using a biomechanical comparison. The purpose of this study was to carry out a computational comparative biomechanics of three different commonly used fixation constructs for the fixation of PMF by finite element analysis (FEA). METHODS: Computed tomography (CT) images were used to reconstruct three dimensional (3D) model of the tibia...

Displaced osteochondral fractures of the body of talus quite often require a malleolar osteotomy to gain access to the fracture fragment during internal fixation. We describe a case report in which access to a displaced osteochondral fracture of the lateral talar dome was achieved using an arthroscopy-assisted fibular tunnel approach. This technique resulted in satisfactory fracture healing and a satisfactory clinical outcome.

The study presents an overview of the most common radiography and CT-based classifications of posterior malleolar fractures in ankle fracture-dislocations. Their analysis has shown that posterior malleolar fractures largely vary in size and shape. Evaluation of fractures by plain radiographs is inadequate. A detailed assessment of the fragment shape and course of fracture lines requires CT examination in all three projections, followed by 3D CT reconstructions.Key words: ankle fracture - dislocations trimalleolar fractures posterior malleolar fractures classification...

Maisonneuve fractures are relatively well known in the sports medicine, and orthopedic communities, however, can be commonly missed among primary care providers. The following case outlines an active duty 35-yr-old female patient who presented with acute pain on the left ankle and lower leg after she misjudged a step. The injury is a combination of high fibular and medial malleolar fractures with a disruption of the tibiofibular syndesmosis ligaments. This is a result of extreme external rotation and pronation of a fixed foot...

BACKGROUND: This study analyzes position of the peroneal tendons and status of the superior peroneal retinaculum (SPR) whenever a lateral malleolar bony flake fracture occurs. METHODS: Twenty-four patients had a lateral malleolar bony fleck on anteroposterior ankle radiographs, either in isolation or associated with other hindfoot injuries. We studied size of the bony flecks, presence or absence of peroneal tendon dislocation and pathoanatomy on CT scans. RESULTS: In 11 patients, a small bony fleck lies within the superior peroneal retinaculum and contiguous periosteum, which are stripped off the lateral fibula (Class II lesions)...
