Abstract Background This study aimed to analyze quantitative correlation between the posterior malleolus fracture and fixation rotational stability of ankle explore supplementary surgical indications for fracture. Methods Twenty fresh frozen cadaver specimens were selected dissected. Based on tibial insertion ligament complex, model supination external rotation stage 3 with a malleolar fragment...

The rotation of the tibia and subtalar motion are being taken into account in some of the newer techniques for leg bracing. It is the purpose of this paper to investigate the precise relationship between these two movements. The rotation of the tibia in a horizontal plane, occurring during stance, is rotation about a simple vertical axis to a limited degree only. The major range of tibial rotat...

Background The use of navigation for total knee arthroplasty (TKA) improves limb alignment in the coronal and sagittal planes. However, similar improvements in femoral and tibial component rotation have not yet been realized using currently available systems. Methods We developed a modified navigated TKA technique in which femoral rotation was set using the resected tibial plane as the refere...

BACKGROUND Dynamic US examination is a convenient, accurate, inexpensive and reproducible diagnostic tool for assessing the integrity of the distal tibiofibular syndesmosis in ankle injuries. However normal values for physiological functional widening of the anterior tibiofibular clear space in healthy subjects has yet to be determined. The purpose of this study was to determine normal values f...

Abstract Lateral ankle sprains are highly prevalent during sporting activities, as it accounts for approximately 60% of all athletic injuries. There is currently a paucity research which provides kinetic and kinematic assessments giving-way episodes the joint. The aim this case study was to examine kinetics kinematics knee episode in female ice hockey player 180-degree pivot turn, conducted 3D ...

OBJECTIVE To compare the kinematics of lower limb joints between individuals with and without chronic ankle instability (CAI) during cross-turn and -cutting movements. DESIGN Cross-sectional study. SETTING Motion analysis laboratory. PARTICIPANTS Twelve subjects with CAI and twelve healthy controls. MAIN OUTCOME MEASURES Hip flexion, adduction, and internal rotation, knee flexion, and a...

Background. This study was designed to evaluate the function of the foot undergoing the procedure of percutaneous Achilles tenotomy (PAT) in case of clubfoot management in terms of gait analysis. Methods. Nineteen patients with unilateral clubfeet were retrospectively reviewed from our database from July 2012 to June 2016. The result in all the cases was rated as excellent according to the scal...

BACKGROUND AND PURPOSE Within dynamical pattern theory, ankle motion can be proposed to be a control variable, and solid ankle-foot orthoses (SAFOs) can be considered a constraint to ankle movement. The purpose of this study was to examine the effect of SAFOs on movement patterns used to rise from the supine position to erect stance. SUBJECTS Thirty-nine nondisabled young adults, ranging in a...

PURPOSE To investigate anatomic variations of neurovascular structures in the ankle and the safety margin for arthroscopic portals. METHODS 11 left and 12 right ankles from 8 female and 15 male fresh cadavers of Chinese ethnicity aged 53 to 88 (mean, 68) years were used. The ankle was standardised in a plantigrade position, zero-degree inversion, and neutral rotation. Four ankle portals, name...

The purpose of this study was to evaluate how soft tissue surgery for correcting equinus deformity affects the kinematic and kinetic parameters of the ankle and proximal joints. Sixteen children with spastic hemiplegic cerebral palsy and equinus deformities (age range 3-16 years) were included. Soft tissue surgeries were performed exclusively on the ankle joint area in all subjects. Using compu...
