A Case Series Comparing T+LRTI to Partial Trapeziectomy for Thumb Osteoarthritis

McMaster University20 enrolled

Overview

The purpose of this study was to measure the differences in Health Related Quality of Life (HRQOL) and functional measurements between two groups of patients with Carpometacarpal Osteoarthritis of the thumb.

Two patient groups, who have been diagnosed with Carpometacarpal Osteoarthritis of the thumb were compared to measure the Health Related Quality of life (HRQOL) and functional outcomes following two different surgical procedures. The first procedure is currently the most used procedure is North America, Trapeziectomy with Ligament Reconstruction and Tendon Interposition (T+LRTI); this procedure is compared to Partial Trapeziectomy and Tendon Interposition (PT+TI). HRQOL is measured using three questionnaires: one generic, one condition specific and one to measure utility (costs). Patients received their procedures from the respective surgeons and then came in for regular follow up at 1, 3, 6 and 12 months. At these follow up visits the questionnaires and functional measurements (including grip, key pinch and tip pinch strength), were completed

Conditions

Arthritis Health Related Quality of Life Osteoarthritis

Interventions

T+LRTIPROCEDURE

T+LRTI is the most commonly used procedure, it removes the entire trapezium

PT+TIPROCEDURE

The PT+TI is less invasive than the T+LRTI as only part of the trapezium is removed

Outcomes

Primary Outcomes

Change in Health Related Quality of Life (HRQOL) as measured by the Short Form 36v2 (SF-36)

The Short-Form 36v2 \[SF-36\] is a Generic HRQOL questionnaire

Time frame: 1 week pre-operatively plus 1, 3, 6 and 12 month post-operatively

Change in Health Related Quality of Life (HRQOL) as measured by the Disabilities of the Arm, Shoulder and Hand (DASH)

The DASH is a condition specific questionnaire

Time frame: 1 week pre-operatively plus 1, 3, 6 and 12 month post-operatively

Change in HRQOL as measured by The EuroQol-5D-3L [EQ-5D]

The EQ-5D is a questionnaire that allows utility to be calculated

Time frame: 1 week pre-operatively plus 1, 3, 6 and 12 month post-operatively

Secondary Outcomes

Change in functional performance as measured by Grip Strength

Force applied by the hand, measured by a goniometer in kilograms

Time frame: 1 week pre-operatively and 3, 6 and 12 month post-operatively

Change in functional performance as measured by Two-Point Pinch Strength

Force applied by the tip of the thumb and the tip of the index finger, measured by a goniometer in kilograms

Time frame: 1 week pre-operatively and 1, 3, 6 and 12 month post-operatively

Change in functional performance as measured by Key Pinch Strength

Force applied by the pad of the thumb and lateral surface of the index finger, measured by a goniometer in kilograms

Time frame: 1 week pre-operatively and 3, 6 and 12 month post-operatively
