Introduction: Muscle motor points are considered the best sites for electrode positioning in electrical stimulation and, by some researchers, for botulinum neurotoxin injections. The aim of this study is to locate the motor points in the gracilis muscle to improve muscle function maintenance and treatment of spasticity.

Material And Methods: Ninety-three gracilis muscles (49 right, 44 left), fixed in 10% formalin solution, were subjected to the research.

Unlabelled: Anterior cervical controllable antedisplacement and fusion (ACAF) is utilized for the treatment of symptomatic ossification of the posterior longitudinal ligament (OPLL). The aims of the procedure are to directly relieve ventral compression of the spinal cord, to reconstruct the spinal canal and restore cervical alignment, and to achieve satisfactory clinical recovery.

Description: The detailed steps to perform ACAF have been described previously.

Objective: Kyphoplasty (KP) is a surgery used to reduce pain and increase stability by injecting medical bone cement into broken vertebrae. The purpose of this study was to determine the ideal amount of cement and injection site by analyzing forces with the finite element method.

Methods: We modeled the anatomical structure of the vertebra and injected the cement at T12.

Background: Osteoporotic vertebral fracture (OVF) is a common spinal fracture in the elderly population treated with conservative or surgical techniques. Patients with such fractures may experience chronic pain due to nonunion and instability, deformity with kyphosis and neurologic symptoms due to neural compression. Surgical interventions have definite roles in treatments especially when conservative therapy fails.

We present a rheometer that combines the possibility to perform in situ X-ray experiments with a precise and locally controlled uniaxial extensional flow. It thus allows us to study the crystallization kinetics and morphology evolution combined with the rheological response to the applied flow field. A constant uniaxial deformation rate is ensured, thanks to a fast control scheme that drives the simultaneous movement of the top and bottom plates during a pulling experiment.
