Thread trigger finger release is an ultrasound guided minimally invasive procedure of performing trigger finger release using a piece of surgical dissecting thread as a dividing element, instead of using a scalpel or a needle tip as in the situation of open trigger finger release or percutaneous trigger finger release.

Ultrasound vibrations with frequencies above the human hearing range

Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz in healthy young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

Minimally invasive procedure surgical techniques that limit the size of incisions needed and so reduce wound healing time, associated pain and risk of infection

Minimally invasive procedures encompass surgical techniques that limit the size of incisions needed and so lessen wound healing time, associated pain and risk of infection. Surgery by definition is invasive and many operations requiring incisions of some size are referred to as open surgery, in which incisions made can sometimes leave large wounds that are painful and take a long time to heal. Minimally invasive procedures have been enabled by the advance of various medical technologies. An endovascular aneurysm repair as an example of minimally invasive surgery is much less invasive in that it involves much smaller incisions than the corresponding open surgery procedure of open aortic surgery. This minimally invasive surgery became the most common method of repairing abdominal aortic aneurysms in 2003 in the United States.

Trigger finger, also known as stenosing tenosynovitis, is a disorder characterized by catching or locking of the involved finger. Pain may occur in the palm of the hand or knuckles. The name is due to the popping sound made by the affected finger when moved. Most commonly the ring finger or thumb is affected.

The technique of thread trigger finger release is the application of Guo Technique [2] and the procedure is similar to that of the thread carpal tunnel release. [3]

Thread carpal tunnel release

Thread carpal tunnel release (TCTR) is a minimally-invasive procedure of performing carpal tunnel release using a piece of surgical dissecting thread as a dividing element. This is instead of using a scalpel as in the situation of open carpal tunnel release (OCTR) or endoscopic carpal tunnel release (ECTR).

The successful rate of TTFR is high and there are almost no complications such as incomplete release, neurovascular or flexor tendon or A2 pulley injury, infection, bow string, or reflex sympathetic dystrophy. Triggering and locking are resolved, and complete extension and flexion are recovered immediately after the release in all cases. The patient does not take painkillers postoperatively. Most patients returned to their light daily activity with caution right after the procedure.

Anatomical terms of motion Wikimedia list article

Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the joints. Anatomists use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing the uniqueness of the movements such as those of the hands, feet, and eyes.

The technique of TTFR is clinically feasible, safe and effective.

Carpal tunnel syndrome Human Syndrome

Carpal tunnel syndrome (CTS) is a medical condition due to compression of the median nerve as it travels through the wrist at the carpal tunnel. The main symptoms are pain, numbness and tingling in the thumb, index finger, middle finger and the thumb side of the ring finger. Symptoms typically start gradually and during the night. Pain may extend up the arm. Weak grip strength may occur, and after a long period of time the muscles at the base of the thumb may waste away. In more than half of cases, both sides are affected.

Laparoscopy procedure in which a laparoscope is inserted through a small incision near the navel to examine abdominal and pelvic organs

Laparoscopy invented by George Kelling in 1901, in Germany, is an operation performed in the abdomen or pelvis using small incisions with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.

Arthroscopy

Arthroscopy is a minimally invasive surgical procedure on a joint in which an examination and sometimes treatment of damage is performed using an arthroscope, an endoscope that is inserted into the joint through a small incision. Arthroscopic procedures can be performed during ACL reconstruction.

Tenosynovitis is the inflammation of the fluid-filled sheath that surrounds a tendon, typically leading to joint pain, swelling, and stiffness. Tenosynovitis can be either infectious or noninfectious. Common clinical manifestations of noninfectious tenosynovitis include de Quervain tendinopathy and stenosing tenosynovitis

Tracheotomy temporary surgical incision into the trachea

Tracheotomy, or tracheostomy, is a surgical procedure which consists of making an incision (cut) on the anterior aspect (front) of the neck and opening a direct airway through an incision in the trachea (windpipe). The resulting stoma (hole) can serve independently as an airway or as a site for a tracheal tube or tracheostomy tube to be inserted; this tube allows a person to breathe without the use of the nose or mouth.

Dupuytrens contracture Disease with gradual bending of the fingers due to scar tissue build up within the palms

Dupuytren's contracture is a condition in which one or more fingers become permanently bent in a flexed position. It usually begins as small hard nodules just under the skin of the palm, then worsens over time until the fingers can no longer be straightened. While typically not painful, some aching or itching may be present. The ring finger followed by the little and middle fingers are most commonly affected. The condition can interfere with preparing food, writing, and other activities.

Distal radius fracture Fracture of the radius bone near the wrist

A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. Symptoms include pain, bruising, and rapid-onset swelling. The wrist may be deformed. The ulna bone may also be broken.

Robot-assisted surgery surgical procedure aided by robotic systems

Robotic surgery are types of surgical procedures that are done using robotic systems. Robotically-assisted surgery was developed to try to overcome the limitations of pre-existing minimally-invasive surgical procedures and to enhance the capabilities of surgeons performing open surgery.

Radiofrequency ablation Surgical procedure

Radiofrequency ablation (RFA) is a medical procedure in which part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from medium frequency alternating current. RFA is generally conducted in the outpatient setting, using either local anesthetics or conscious sedation anesthesia. When it is delivered via catheter, it is called radiofrequency catheter ablation.

Neurolysis is the application of physical or chemical agents to a nerve in order to cause a temporary degeneration of targeted nerve fibers. When the nerve fibers degenerate, it causes an interruption in the transmission of nerve signals. In the medical field, this is most commonly and advantageously used to alleviate pain in cancer patients.

Scaphoid fracture Fracture of the scaphoid bone in the wrist

A scaphoid fracture is a break of the scaphoid bone in the wrist. Symptoms generally includes pain at the base of the thumb which is worse with use of the hand. The anatomic snuffbox is generally tender and swelling may occur. Complications may include nonunion of the fracture, avascular necrosis, and arthritis.

Pronator teres syndrome

Pronator teres syndrome is a compression neuropathy of the median nerve at the elbow. It is rare compared to compression at the wrist or isolated injury of the anterior interosseous branch of the median nerve.

Minimally invasive spine surgery, also known as MISS, has no specific meaning or definition. Basically, it is marketing language that implies a lack of severe invasion, that may or may not be the case. The old style open-spine surgery for a simple disc problem used to require a 5-6 inch incision and a month in the hospital, 60 years ago. Miss techniques utilize more modern technology, advanced imaging techniques and special medical equipment to reduce tissue trauma, bleeding, radiation exposure, hospital stays and recovery by minimizing the size of the incision. Modern endoscopic procedures can be done through a 2 to 5 mm skin opening, with no internal cutting. By contrast, procedures done with a microscope require skin openings of approximately one inch, or more. Since the one inch cut goes all the way down, it can only be called relatively MISS.

Congenital trigger thumb

Congenital trigger thumb is a trigger thumb in infants and young children. Triggering, clicking or snapping is observed by flexion or extension of the interphalangeal joint (IPJ). In the furthest stage, no extension is possible and there is a fixed flexion deformity of the thumb in the IPJ. Cause, natural history, prognosis and recommended treatment are controversial.

Radial dysplasia Radial hemimelia is a congenital longitudinal deficiency of the radius bone of the forearm characterized by partial or total absence of the radius

Radial dysplasia, also known as radial club hand or radial longitudinal deficiency, is a congenital difference occurring in a longitudinal direction resulting in radial deviation of the wrist and shortening of the forearm. It can occur in different ways, from a minor anomaly to complete absence of the radius, radial side of the carpal bones and thumb. Hypoplasia of the distal humerus may be present as well and can lead to stiffness of the elbow. Radial deviation of the wrist is caused by lack of support to the carpus, radial deviation may be reinforced if forearm muscles are functioning poorly or have abnormal insertions. Although radial longitudinal deficiency is often bilateral, the extent of involvement is most often asymmetric.

Carpal tunnel surgery surgery to relieve carpal tunnel syndrome

Carpal tunnel surgery, also called carpal tunnel release (CTR) and carpal tunnel decompression surgery, is a surgery in which the transverse carpal ligament is divided. It is a surgical treatment for carpal tunnel syndrome (CTS) and recommended when there is constant numbness, muscle weakness, or atrophy, and when night-splinting no longer controls intermittent symptoms of pain in the carpal tunnel. In general, milder cases can be controlled for months to years, but severe cases are unrelenting symptomatically and are likely to result in surgical treatment. Approximately 500,000 surgical procedures are performed each year, and the economic impact of this condition is estimated to exceed $2 billion annually.

Linburg–Comstock variation is an occasional tendinous connection between the flexor pollicis longus and the flexor digitorum profundus of the index, the middle finger or both. It is found in around 21% of the population. It is an anatomical variation in human, which may be viewed as a pathology if causes symptoms. It was recognised as early as the 1800s, but was first described by Linburg and Comstock in 1979.
