What type of joint is the hip?
The hip joint is a ball-and-socket joint that allows motion and gives stability needed to bear body weight. The socket area (acetabulum) is inside the pelvis. The ball part of this joint is the top of the thighbone (femur). It joins with the acetabulum to form the hip joint.
What is perineal post?
Perineal Post provides countertraction and is made of radiolucent carbon fiber to enhance C-arm imaging. The post pad relieves pressure on the perineal area and is made of disposable foam.
What causes hip labral tears?
Labral tears are typically caused by overuse, traumatic injuries or abnormalities in the shape or alignment of the hip bones. Hip labral tears can be treated with or without surgery. If surgery is needed, it can be done with a minimally invasive approach.
What is hip joint capsule?
The hip joint capsule is strong and dense, and is attached above to the acetabular margin 5-6 mm beyond its labrum, in front to the outer labral aspect and, near the acetabular notch, to the transverse acetabular ligament and the adjacent rim of the obturator foramen.
What is a hip flexion?
A hip flexor muscle is a muscle that functions in flexing the hip, ie bringing the knee closer to the chest. Hip flexion is maximal with a high, forward kick that brings the leg above the level of the waist. Every time you take a step, you are using your hip flexor muscles.
Is hip arthroscopy major surgery?
Hip arthroscopy is rarely considered major surgery. The whole process often takes less than two hours and only involves two or three incisions in the skin. Patients can bear weight on their hips within a few weeks. Because arthroscopy isn’t invasive, it is often successful in treating patient hip issues.
What kind of anesthesia is used for hip arthroscopy?
General anesthesia (you are asleep for the entire operation) is most commonly used for hip arthroscopy. However, regional anesthesia, such as spinal or epidural (you are awake but numb from the waist down), can also be used.
What is hip traction?
For people with hip fractures, traction involves either using tapes (skin traction) or pins (skeletal traction) attached to the injured leg and connected to weights via a pulley. The application of traction before surgery is thought to relieve pain and make the subsequent surgery easier.
What is a hip distractor?
Hip distraction is a necessary and vital component in maneuvering you for arthroscopic entry into your hip joint. It’s used in correcting and repairing your hip components while keeping the neighboring muscles in place. Some conditions treated with hip distraction surgery are: Labrum tears of the acetabulum.
Is labrum a ligament?
This rim of cartilage is called the “labrum”. Ligaments surround and connect the ball to the socket. These ligaments attach directly to the ball but attach to the labrum as opposed to the bone at the socket. The labrum attachment to the bone is the “weak link” of this setup.
Where is hip labrum pain located?
Symptoms of a labral tear include deep pain in the groin or at the front of the hip. People often describe the location of the pain in a “C”-shaped region over the hip joint. You may also experience a sensation of locking or catching in the hip along with decreased range of motion.
What is the use of a buffer?
This method is also known as anti-aliased or area-averaged or accumulation buffer. This method extends the algorithm of depth-buffer (or Z Buffer) method. As the depth buffer method can only be used for opaque object but not for transparent object, the A-buffer method provides advantage in this scenario.
What is the buffer browser extension?
The Buffer browser extension makes sharing content even quicker and easier! It allows you to open the composer on any web page and add posts right to your queue, without having to go back to your dashboard. The extension is currently supported on Chrome, Firefox, and Safari.
What are the two basic methods for constructing buffers?
The two basic methods for constructing buffers, Euclidean and geodesic, are described as follows: Euclidean buffers measure distance in a two-dimensional Cartesian plane, where straight-line or Euclidean distances are calculated between two points on a flat surface (the Cartesian plane).
What is the anti-aliased buffer method?
This method is also known as anti-aliased or area-averaged or accumulation buffer. This method extends the algorithm of depth-buffer (or Z Buffer) method.
