LLow ankle sprains are common injuries in young athletes. Hence, it is imperative that low ankle sprains are diagnosed and treated quickly and effectively. We reviewed the: (1) anatomy; (2) imaging; (3) physical exam findings; and (4) treatment modalities regarding these injuries. Plain radiographs are standard of care and routine MRI is not recommended for suspected sprains. However, physical exam findings often may guide management decisions. The majority of patients diagnosed with low ankle sprains are treated with a one- to two-week immobilization period with physical therapy focused on peroneal proprioception and strength...

CONTEXT:   One of the major concerns after an acute lateral ankle sprain is the potential for development of chronic ankle instability (CAI). The existing research has determined that clinician-delivered plantar massage improves postural control in those with CAI. However, the effectiveness of self-administered treatments and the underlying cause of any improvements remain unclear. OBJECTIVES:   To determine (1) the effectiveness of a self-administered plantar-massage treatment in those with CAI as well and (2) whether the postural-control improvements were due to the stimulation of the plantar cutaneous receptors...

The purpose of this study was to investigate the effect of load carriage on the kinematics and kinetics of the ankle and knee joints during uphill walking, including joint work, range of motion (ROM), and stance time. Fourteen males walked at a self-selected speed on an uphill (15°) slope wearing military boots and carrying a rifle in hand without a backpack (control condition) and with a backpack. The results showed that the stance time significantly decreased with backpack carriage (p<.05). The mediolateral impulse significantly increased with backpack carriage (p<...

BACKGROUND: Isolated lateral malleolar fractures may result from a supination-external rotation (SER) injury of the ankle. Stable fractures maintain tibiotalar congruence due to competent medial restraints and can be treated nonoperatively with excellent functional results and long-term prognosis. Stability might be assessed with either stress radiographs or weightbearing radiographs. METHODS: A consecutive series of patients with closed SER fractures (presumed AO 44-B1) were prospectively enrolled from 2008 to 2015...

REVIEW
Alastair Younger, Andrea Veljkovic
Ankle replacement results may be compromised by malposition of the components. An anterior displacement can be measured on a lateral standing radiograph. The ankle may appear anteriorly translated because the ankle is overstuffed, the heel cord is tight, or the posterior capsule is tight. In ankle instability with degenerative arthritis, the talus may be anteriorly translated, internally rotated, and in varus. In an ankle replacement, this deformity may persist and will require correction. On occasion, the talus is inserted too anterior; revision to a flat cut talar component and posterior translation of the talar component will result in correction...

Specific anatomic variations of the ankle mortise may be found in people with ankle instability. The purpose was to evaluate the fibular and talus position in subjects with mechanical ankle instability (MAI). In this study, MR images of 54 patients with MAI and 51 patients from the author's institution for reasons unrelated to ankle instability were reviewed. The position of the fibular in relation to the talus (axial malleolar index, AMI) and medial malleolus (intermalleolar index, IMI) were evaluated at the axial plane...

Reconstruction of unstable syndesmotic injuries is not trivial, and there is no generally accepted treatment guidelines. Thus, there still remain considerable controversies regarding diagnosis, classification and treatment of syndesmotic injuries. Syndesmotic malreduction is the most common indication for early re-operation after ankle fracture surgery, and widening of the ankle mortise by only 1 mm decreases the contact area of the tibiotalar joint by 42%. Outcome of ankle fractures with syndesmosis injury is worse than without, even after surgical syndesmotic stabilization...
