Jianren Wang, Junkai Xu, Peter B Shull
Vertical jump height is widely used for assessing motor development, functional ability, and motor capacity. Traditional methods for estimating vertical jump height rely on force plates or optical marker-based motion capture systems limiting assessment to people with access to specialized laboratories. This paper presents a novel algorithm for estimating vertical jump height based on foot-worn inertial sensors. Twenty healthy subjects performed countermovement jumping trials and maximum jump height was determined via inertial sensors located above the toe and under the heel and was compared with the gold standard maximum jump height estimation via optical marker-based motion capture...

BACKGROUND: Calcaneal insufficiency avulsion (CIA) fractures often present with neuropathic etiology, such as Charcot neuroarthropathy (CN). Under the same surgical procedures, the outcomes of CIA fractures are less desirable, compared to the outcomes of the traumatic calcaneal avulsion fractures. Here, the study suggests Achilles tenodesis technique using suture anchor after resection of the CIA fracture fragments could provide satisfactory clinical results in the cases of surgically indicated CIA fractures...

Hao Guo, Hai-Lin Xu, Hao Lu, Bao-Guo Jiang
First metatarsophalangeal (MTP) arthrodesis is commonly used to treat many end-stage first MTP diseases. The most widely used scale for measuring the clinical outcomes after this procedure, the American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal scale, has not been adequately validated and does not measure specific foot functions. Another outcome measure, the patient-reported Foot and Ankle Outcome Score (FAOS) has acceptable construct validity but poor content validity. The FAOS scale has 42 questions, many of which are unrelated to the hallux...

PURPOSE: Suture button devices for tibiofibular syndesmosis injuries provide semirigid dynamic stabilization, but complications including knot irritation have been reported. No randomized trials of the new knotless suture button devices have been performed. We hypothesized that knotless suture button devices eliminate knot irritation and facilitate quicker return to sports. This study was performed to compare the clinical outcomes, complication rates, and time to return to sports between a new knotless suture button device and syndesmotic screw fixation...

Wide-awake surgery has potential advantages for treating extensor or flexor tendon injury. We present a case of chronic extensor hallucis longus injury treated with turn-down reconstruction using wide-awake surgery with a selective nerve block. To the best of our knowledge, this is the first such case reported. The patient had dropped a knife proximal to the right hallux metatarsophalangeal joint. Because direct suturing was thought to be difficult, turn-down reconstruction was performed under a selective nerve block...

Asymmetries of the rowing stroke cycle have been assessed with reference to kinematics and foot-force measures in laboratory testing environments. It remains unclear how asymmetries in propulsive kinetic measures are related to on-water rowing performance. A new approach for the evaluation of both global and local asymmetries across the entire movement was used to assess the continuous role of asymmetries and whether these change according to level of competitive representation. Twenty seven highly skilled female rowers (national and international competition level), rowing at 32 strokes per minute in a single scull boat were evaluated...

Disorders of the foot and ankle are some of the most frequent ones affecting the musculoskeletal system and have a great impact on patients' quality of life. Accurate diagnosis is an important clinical challenge because of the complex anatomy and function of the foot, that make it difficult to locate the source of the pain by routine clinical examination. In the study of foot pathology, anatomical imaging (radiography, magnetic resonance imaging [MRI], ultrasound and computed tomography [CT]) and functional imaging (bone scan, positron emission tomography [PET] and MRI) techniques have been used...
