Effect of self-curing elastomeric material under cranio-caudal cyclic loading

Pedicle screws can be augmented with polymethylmethacrylate (PMMA) cement through cannulated and fenestrated pedicle screws to improve screw anchorage. To overcome the drawbacks of PMMA, a modified augmentation technique applying a self-curing elastomeric material into a balloon-created cavity prior to screw insertion was developed and evaluated. The aim of the study was to compare the effect of the established and novel augmentation technique on pedicle screw anchorage in a biomechanical in vitro experiment. Patient Education

Efficacy of intravenous acetaminophen in multimodal management for pain relief

The efficacy of intravenous acetaminophen in multimodal pain management in patients undergoing total knee arthroplasty (TKA) is controversial. The purpose of this meta-analysis was to compare the efficacy of intravenous acetaminophen versus placebo in TKA. Randomized controlled trials (RCTs) or retrospective cohort studies (RCSs) concerning related topics were retrieved from PubMed (1996–June 2018), Embase (1980–June 2018), and the Cochrane Library (CENTRAL June 2018). Any studies comparing intravenous acetaminophen with a placebo were included in this meta-analysis. Meta-analysis results were collected and analyzed by Stata 12.0. Subgroup analysis was performed according to the general characteristics of the patients.

Exploratory analysis of predictors of revision surgery for proximal junctional kyphosis

Proximal junctional kyphosis (PJK) following adult spinal deformity (ASD) surgery in elderly patients is markedly influenced by osteoporosis causing additional vertebral fracture and loosening of pedicle screws (PS). This study aimed to investigate the association between mean bone density represented in Hounsfield units (HU) on spinal computed tomography (CT) and revision surgery for PJK or postoperative additional vertebral fracture following ASD surgery in elderly patients.

Hip

A severe impact — in a car crash, for example — can cause hip fractures in people of all ages. In older adults, a hip fracture is most often a result of a fall from a standing height. In people with very weak bones, a hip fracture can occur simply by standing on the leg and twisting. Signs and symptoms of a hip fracture include: Inability to move immediately after a fall Severe pain in your hip or groin Inability to put weight on your leg on the side of your injured hip Stiffness, bruising and swelling in and around…

Knee

In most cases, a broken kneecap is caused by a direct blow to the front of the knee from a car accident, sports or a fall onto concrete. Most kneecap fractures occur in people between the ages of 20 and 50. Symptoms may include: Severe pain in and around the kneecap Swelling Pain when moving the knee in both directions Difficulty extending the leg or doing a straight-leg raise A deformed appearance of the knee due to the fractured pieces Tenderness when pressing on the kneecap

Elbow

An olecranon fracture usually causes sudden, intense pain and can prevent you from moving your elbow. Other signs and symptoms of a fracture may include: Swelling over the “tip” or back of the elbow Bruising around the elbow. Sometimes, this bruising travels up the arm towards the shoulder or down the forearm towards the wrist. Tenderness to the touch Numbness in one or more fingers Pain with movement of the elbow or with rotation of the forearm A feeling of instability in the joint, as if your elbow is going to “pop out.”

Shoulders

The main symptoms of a frozen shoulder are pain and stiffness that make it difficult or impossible to move it. If you have frozen shoulder, you’ll likely feel a dull or achy pain in one shoulder. You might also feel the pain in the shoulder muscles that wrap around the top of your arm. You might feel the same sensation in your upper arm. Your pain could get worse at night, which can make it hard to sleep. You’ll typically go through three phases with a frozen shoulder. Each has its own unique symptoms and timeline. Freezing stage: You develop…

Arthroscopy & Sports Medicine

Invasive surgical procedure on a joint for damage treatment using an endoscope inserted into the joint through a small incision. Sports medicine is a field of medicine that is associated  with physical fitness and the therapy and prevention of sport-related and exercise-related injuries. In other words, it revolves around the prevention, diagnosis, treatment, and rehabilitation of athletic activity injuries. The objective of sports medicine is to assist individuals in safe and efficient exercise to attain their objectives of practice. Specialists treat an array of physical complications involving acute trauma such as fractures, sprains, strains, and dislocations as well as chronic overuse injuries. These conditions are mainly treated with arthroscopic surgery. Arthroscopy is…

Trauma & Fractures

A result of high impact or stress, or certain medical conditions that weaken the bones. A fracture is a crack or break in the bone which may appear in any bone of the body. Dislocations, fractures, and severe injuries to the soft tissue are traumatic conditions. Trauma and fractures may be prevalent in patients of all ages due to impulsive incidents such as car accidents or drastic falls. In certain cases, fractures may also be a result of disease which are known as pathological fractures. Alternatively stated, fractures act as a consequence of traumatic impact or stress, or due to certain medical conditions that weaken the bones…
