  2. Ulnar collateral ligament reconstruction - Wikipedia

    en.wikipedia.org/wiki/Ulnar_collateral_ligament...

    A harvested tendon, such as the palmaris tendon [11] from the forearm of the same or opposite elbow, the patellar tendon, hamstring, toe extensor or a donor's tendon , is then woven in a figure-eight pattern through the holes and anchored. [10] The ulnar nerve is usually moved to prevent pain, as scar tissue can apply pressure to the nerve. [11]

  3. Arthrogram - Wikipedia

    en.wikipedia.org/wiki/Arthrogram

    MR arthrography is most often used in evaluation of the hip and acetabular labrum, of the shoulder rotator cuff and glenoid labrum, and less often in the wrist. [2] Arthrograms can be diagnostic and therapeutic. Therapeutic arthrograms often distend the joint with cortisone and lidocaine, with a common site being the shoulder.

  4. Determining the number of clusters in a data set - Wikipedia

    en.wikipedia.org/wiki/Determining_the_number_of...

    The number of clusters is chosen at this point, hence the "elbow criterion". In most datasets, this "elbow" is ambiguous, [ 1 ] making this method subjective and unreliable. Because the scale of the axes is arbitrary, the concept of an angle is not well-defined, and even on uniform random data, the curve produces an "elbow", making the method ...

  5. Humeroulnar joint - Wikipedia

    en.wikipedia.org/wiki/Humeroulnar_joint

    The humeroulnar joint (ulnohumeral or trochlear joint [1]) is part of the elbow-joint. It is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. [1] It is classified as a simple hinge-joint, which allows for movements of flexion, extension and circumduction.

  6. Elbow method (clustering) - Wikipedia

    en.wikipedia.org/wiki/Elbow_method_(clustering)

    Using the "elbow" or "knee of a curve" as a cutoff point is a common heuristic in mathematical optimization to choose a point where diminishing returns are no longer worth the additional cost. In clustering, this means one should choose a number of clusters so that adding another cluster doesn't give much better modeling of the data.

  7. Arthroscopy - Wikipedia

    en.wikipedia.org/wiki/Arthroscopy

    Later, he developed a double-contrast approach to improve visibility. [30] He gave up endoscopy in 1930, and his work was largely neglected for several decades. While he is often considered the inventor of arthroscopy of the knee, [ 31 ] the Japanese surgeon Masaki Watanabe , MD, receives primary credit for using arthroscopy for interventional ...

  8. Anterior ligament of elbow - Wikipedia

    en.wikipedia.org/wiki/Anterior_ligament_of_elbow

    The anterior ligament of the elbow is a broad and thin fibrous layer covering the anterior surface of the joint.. It is attached to the front of the medial epicondyle and to the front of the humerus immediately above the coronoid and radial fossae below, to the anterior surface of the coronoid process of the ulna and to the annular ligament, being continuous on either side with the collateral ...

  9. Olecranon - Wikipedia

    en.wikipedia.org/wiki/Olecranon

    The olecranon (/ oʊ ˈ l ɛ k r ə n ɒ n /, from Greek olene 'elbow' and kranon 'head'), is a large, thick, curved bony process on the proximal, posterior end of the ulna.It forms the protruding part of the elbow and is opposite to the cubital fossa or elbow pit (trochlear notch).
