A stable and precise articulation of the distal tibiofibular syndesmosis is essential for normal motion of the ankle joint. Injury to the syndesmosis occurs through rupture or bony avulsion of the syndesmotic ligament complex. External rotation of the talus has been identified as the major mechanism of syndesmotic injury. None of the syndesmotic stress tests was sensitive or specific; therefore...

INTRODUCTION: Syndesmotic injuries of the ankle commonly occur via an external rotation force applied to the ankle joint. The effects of rigid or non-rigid fixation of the syndesmotic injury can be assessed by evaluating the three-dimensional kinematics behavior of tibiofibular diastasis. The specific aims of this study were: 1) to determine the physiological range of motion of the distal tibio...

introduction: since most studies on ankle sprain are medical and sports-related and not much epidemiologic and etiologic data from the general population exist in this field, the present study evaluates the relationship between q angle and anthropometric measures with ankle sprain in the general population. methods: in the present case-control study, all of the patients over 18 years age presen...

The joint coordinates systems (JCS) of the hip, knee, and ankle have been extensively described [1, 2, 3]. The principle is to embed a flexion-extension (FE) axis in the proximal segment and an internalexternal rotation (IER) (or adduction-abduction (AA)) axis in the distal segment, following anatomical or functional directions. For the joint displacements, the origins of the proximal and dista...

PURPOSE This study examined differences in ankle motion and plantar pressure between habitually barefoot male (HBM) and habitually shod male (HSM) during vertical jump. METHODS Eighteen habitually barefoot males and twenty habitually shod males volunteered to join the test. Distance between hallux and second toe was measured with Easy-Foot-Scan. Plantar pressure and ankle kinematics were meas...

Yoshida N, Tsuchida Y. BMJ Case Rep 2017. doi:10.1136/bcr-2017-222231 Description A 37-year-old man presented to the emergency department with right lower limb pain after being hit by an excavator. His right ankle was swollen, but no open wounds were observed. Radiography and CT of the right ankle revealed a medial malleolus ankle fracture (figure 1A,B). During his treatment with osteosynthesis...

This study presented a three-pressure-sensor (3PS) system for monitoring ankle supination torque during sport motions. Five male subjects wore a pair of cloth sport shoes and performed 10 trials of walking, running, cutting, vertical jump-landing and stepping-down motions in a random sequence. A pair of pressure insoles (Novel Pedar model W, Germany) was inserted in the shoes for the measuremen...

Sideward movements are associated with high incidences of lateral ankle sprains. Special shoe constructions might be able to reduce these injuries during lateral movements. The purpose of this study was to investigate whether medial compressible forefoot sole elements can reduce ankle inversion in a reactive lateral movement, and to evaluate those elements' influence on neuromuscular and mechan...

Background & Aims: Distal leg, ankle and foot injuries are relatively common; and because of lack of soft tissue and poor blood supply in these areas, one of the common problems in these patients is soft tissue necrosis. Exposed orthopedic implants can be used as open reduction internal fixator (ORIF) in these regions. Methods: During 2013-2014, 14 patients (11 men and 3 women) with a mean age ...
