Brief summary

The oval-8 splint has been developed for many uses in finger pathology and trauma. It has not, however, been used to treat thumb carpometacarpal (CMC) joint arthritis. When treating thumb CMC joint osteoarthritis, splinting is a very widely used and supported treatment option for non-operative management. Many studies have been performed showing that thumb spica splinting in abduction with either a hand based or forearm based splint improves pain. This study aims to compare the effects of a novel splinting approach with oval-8 splints for the hyperextended thumb interphalangeal (IP) joint vs. standardized treatment with Tee Pee splinting (hand based thumb spica) or forearm thumb spica splinting on pain and function of patients with thumb CMC joint arthritis. This is a pilot study will address the following hypothesis: Splinting of the hyperextended thumb IP joint with oval-8 splints will lead to increased DASH scores and decreased pain on physical exam compared to splinting with thumb spica splints in patients with thumb CMC arthritis.

Detailed description

After informed consent is obtained and the patient has met all of the inclusion criteria and non of the exclusion criteria, the patient will be assigned a study ID number. The patient will be randomized with a ratio of 1:1:1 to a splint treatment with either a forearm thumb spica splint, Tee-Pee splint or oval- 8 splint at the time of initial visit to Orthopaedic Hand clinic (week 1 visit). The patient will be fitted and provided with the appropriate splint by Orthopaedic physician. Baseline radiographs (3 views anterior-posterior, lateral and oblique) and data points will be gathered from initial clinic history and physical, as performed per normal clinical protocol: arthritis grade, hand involved, dominant hand, interphalangeal (IP) extension, MCP extension, pinch strength, grip strength, pain scale, location of pain, DASH scores, analgesic use, and work/hobby activity. Additionally, demographic data including age, gender and race/ethnicity will be gathered and patient will be asked to repeat pinch and grip tests with study splint applied and asked to repeat assessment of pain scale.

Design outcomes

Primary

MeasureTime frameDescription
DASH Score12 WeeksThe DASH is scored in two components. The disability/symptom questions (30 items scored 1-5) includes the following scoring categories: no difficulty - unable, not at all - extremely, not limited at all - unable, none - extreme, no difficulty - so much difficulty that I can't sleep, and strongly disagree - strongly agree. At least 27 out of 30 items must be completed for a score to be calculated. The assigned values for all completed responses are summed and averaged, producing a score out of five. The second section high performance sport/music or work section. This section of 4 items scored 1-5 includes no difficulty - unable, scoring category. The scoring calculations are the same for this area.

Secondary

MeasureTime frameDescription
Pain Score12 WeeksThe general pain scale ranges 0 - 10, with 0 being no pain and 10 being worst possible pain. Pinch pain and Grip pain will the measured with and without the splint. The ranges are the same for all pain scales.
