Brief Summary

Trigger finger is a common upper limb impairment associated with a significant decrease in quality of life, hand dexterity and strength as well as increased pain while complying daily activities of living. Trigger finger can be managed through the surgical release of the ligaments in the affected finger. The open surgical release of trigger finger can be accomplished through multiple incision types. As such, each incision may present different risks of harming or disturbing the underlying anatomy in the hand. This study aims to assess the variation in three incisional techniques (oblique, transverse and vertical) to determine which incision is preferential to improve scar aesthetics, increase hand function and minimize complications. Patients will be observed following surgery and information about hand function and quality of life will be obtained through the administration of questionnaires. Data will be collected at four time-points, one prior to and three following surgery.

Trigger Finger

Keywords

Scar; Function; Health-Related Quality of Life

Outcome Measures

Primary Outcomes (1)

• Change in Health-Related Quality of Life related to hand function

  Outcome measured through the Michigan Hand Questionnaire (MHQ). The MHQ has a total score of 100; the lowest possible score is 0. A score of 100 on the MHQ indicates the best possible ability.

  1 week prior, 1 day prior, and 1, 3 and 12 months post operation

Secondary Outcomes (1)

• Change in Health-Related Quality of Life related to scar appearance

  1 week prior, 1 day prior, and 1, 3 and 12 months post operation

Study Arms (3)

Transverse incision

At the level of the A1 pulley, a transverse incision will be made and the flexor pulley will be exposed with blunt dissection. The pulley will be transected and the wound will subsequently be closed with 4.0 Monocryl after ensuring complete release

Procedure: Trigger Finger Release through Transverse Incision

Oblique incision

At the level of the A1 pulley, a oblique incision will be made and the flexor pulley will be exposed with blunt dissection. The pulley will be transected and the wound will subsequently be closed with 4.0 Monocryl after ensuring complete release.

Procedure: Trigger Finger Release through Oblique Incision

Vertical incision

At the level of the A1 pulley, a vertical incision will be made and the flexor pulley will be exposed with blunt dissection. The pulley will be transected and the wound will subsequently be closed with 4.0 Monocryl after ensuring complete release.

Procedure: Trigger Finger Release through Vertical Incision

Interventions

Trigger Finger Release through Transverse Incision PROCEDURE

At the level of the A1 pulley, a transverse incision will be made and the flexor pulley will be exposed with blunt dissection. The pulley will be transected and the wound will subsequently be closed with 4.0 Monocryl after ensuring complete release.
