Procedure of thread trigger finger release
Other namesTTFR

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. [1]

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]

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.

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

Carpal tunnel syndrome Medical condition

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 most cases, both hands are affected.

Laparoscopy Minimally invasive operations within the abdominal or pelvic cavities

Laparoscopy 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.

Tenosynovitis Medical condition

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

Trigger finger Medical condition

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.

Tracheotomy Temporary surgical incision to create an airway 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 is named after Guillaume Dupuytren, who first described the underlying mechanism of action followed by the first successful operation in 1831 and publication of the results in The Lancet in 1834. 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 activities such as preparing food and writing.

Minimally invasive procedure

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.

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 broken for life. The ulna bone may also be broken.

Liver biopsy

Liver biopsy is the biopsy from the liver. It is a medical test that is done to aid diagnosis of liver disease, to assess the severity of known liver disease, and to monitor the progress of treatment.

Robot-assisted surgery Surgical procedure

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.

Palmaris longus muscle Muscle of the upper limb

The palmaris longus is a muscle visible as a small tendon located between the flexor carpi radialis and the flexor carpi ulnaris, although it is not always present. It is absent in about 14 percent of the population; however, this number can vary in African, Asian, and Native American populations. Absence of the palmaris longus does not have an effect on grip strength. However, the lack of palmaris longus muscle results in decreased pinch strength in forth and fifth fingers in both sexes. The absence of palmaris longus muscle is more prevalent in females than males.

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.

Flexor retinaculum of the hand A thickened fascia over the carpal tunnel

The flexor retinaculum is a fibrous band on the palmar side of the hand near the wrist. It arches over the carpal bones of the hands, covering them and forming the carpal tunnel.

Osteoid osteoma Medical condition

An osteoid osteoma is a benign (non-cancerous) bone tumor that arises from osteoblasts and some components of osteoclasts. It was originally thought to be a smaller version of an osteoblastoma. Osteoid osteomas tend to be less than 1.5 cm in size. The tumor can be in any bone in the body but are most common in long bones, such as the femur and tibia. They account for 10 to 12 percent of all benign bone tumors. Osteoid osteomas may occur at any age, and are most common in patients between the ages of 4 and 25 years old. Males are affected approximately three times more commonly than females.

Pronator teres syndrome Medical condition

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. It implies a lack of severe surgical invasion. The older style of open-spine surgery for a relatively small disc problem used to require a 5-6 inch incision and a month in the hospital. MISS techniques utilize more modern technology, advanced imaging techniques and special medical equipment to reduce tissue trauma, bleeding, radiation exposure, infection risk, and decreased hospital stays by minimizing the size of the incision. Modern endoscopic procedures can be done through a 2 to 5 mm skin opening. By contrast, procedures done with a microscope require skin openings of approximately one inch, or more.

Congenital trigger thumb Medical condition

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.

Carpal tunnel surgery

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.

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).
