− The use of bone cements of poly(methyl methacrylate) (PMMA) to fix artificial prosthesis to the human body is a habitual method in orthopedic surgery. The hip and the knee joints have a very complex biomechanics and support high loads, for these reasons, acrylic bone cements have to comply with international standards in order to secure the biofuncionality and durability of the implant. In th...

Paradigms have started to shift in the orthodontic world since the introduction of mini-implants in the anchorage armamentarium. For example, miniscrews have allowed the management of wider discrepancies than those treatable by conventional biomechanics because force can be applied directly from the bone-borne anchor unit. Therefore, miniscrews not only free orthodontists from anchorage-demandi...

Although the importance of the anterolateral stabilizing structures of the knee in the setting of anterior cruciate ligament (ACL) injuries has been recognized since many years, most of orthopedic surgeons do not take into consideration the anterolateral structures when performing an ACL reconstruction. Anatomic single or double bundle ACL reconstruction will improve knee stability, but a small...

Objective: Case report of a patient, having persistent low back and leg pain following a L4-L5 surgical laminectomy, who underwent Clinical Biomechanics of Posture (CBP) protocol designed to correct postural distortions. Clinical features: A thirty-five year-old male suffered from low back/leg pain following a work injury despite having a lumbar spine laminectomy 6 months prior to chiropracti...

Giant cell tumor (GCT) is a primary and benign tumor of bone, albeit locally aggressive in some cases, such as in the epi-metaphyseal region of long bones, predominantly the distal end of femur and proximal end of tibia (1). There are a variety of treatments for a bone affected by GCT, ranging from chemotherapy, radiotherapy, embolization, and cryosurgery, to surgery with the use of chemical or...

Background Knee osteoarthritis is a debilitating condition and increased dynamic loading at the knee has been linked with increased progression of the disease. Lateral wedge insoles have been used in clinical practice since the late 1980s. It is theorised that lateral wedge insoles increase the subtalar joint valgus orientation and increase the ankle valgus moment [1], with subsequent reduced k...

Dr. Joseph Hidler, Director of the Center for Applied Biomechanics and Rehabilitation Research at the National Rehabilitation Hospital in Washington DC USA is utilizing the Codamotion (Charnwood Dynamics, UK) and Lokomat robotic gait orthosis (Hocoma AG, Volketswil Switzerland) to study gait patterns in individuals following stroke and spinal cord injury in hopes of developing better therapeuti...

Background Untreated idiopathic scoliosis (IS) may lead to large deformations of the trunk, limiting capacity and biomechanics functions of the chest and exercise capacity, which is closely related to changes in the functioning of the cardio-pulmonary system. The conservative treatment of IS is applied in a brace treatment and various methods of physiotherapy. However, the usage of the brace ma...

OBJECTIVES To investigate the effect of bracing and taping on selected electromyographic, kinematic, and kinetic variables when landing from a jump. METHODS Fifteen netball players performed a jump, so as to land on their dominant limb on a force plate. Electromyographic activity was recorded from the gastrocnemius, tibialis anterior, and peroneus longus muscles. Subjects were also filmed and...

It is well founded that the mechanical environment may regulate bone regeneration in orthopedic applications. The purpose of this study to investigate contributions scaffold and host regeneration, terms subject specificity, implantation site sensitivity environment. Using a computational approach model mechano-driven ingrowth porous titanium scaffolds was simulated distal femur proximal tibia t...
