Brief Summary

This study compares and evaluates differences in movement analysis, patient-reported outcome, radiological assesment and muscular function between patients undergoing carpometacarpal joint arthroplasty with use of modern implants and trapeziectomy with suspensionplasty

Detailed Description

Osteoarthritis of first carpometacarpal joint is the most common degenerative disease of upper limb. According to data available in literature, it affects about 30% of women and 6% of men at the age of 45. Increasing with age, it rises up to 90% in people by the age of 80. Due to more widely spread electronic devices in offices, at work, at home which requires usage of thumb, increase in numbers mentioned above is strongly probable. The main symptoms are: pain, loose of grip strength and loose of function. The latter is most important fact, since about 50% of hand function is possible only with healthy thumb.

In many cases osteoarthritis can be treated by combined NSAIDs and splinting with rehabilitation. Sometimes when symptoms do not respond to non-operative treatment, there is a need for surgery. Trapeziectomy is the most common choice for operative treatment for end-stage basal thumb osteoarthritis. However, many other techniques were developed, there is continuous dispute over selecting the optimal . One of the most promising is arthroplasty using prosthesis. Last years many important advances were made in a design of implant and materials. Moreover the investigators now have many longer outcomes of such operation made in the past. All this data make us think more about using this technique often, since there are papers which show superiority over classical trapeziectomy. Even though there are several studies comparing functional and objective outcome of those techniques, there is a lack of evidence in terms of biomechanical analysis, thenar muscle activity and changes in movement patterns. Moreover there is no study published so far which considers modern implants and trapeziectomy with suspensionplasty. The aim of the study is to examine relationships between movement analysis (kinematic and functional outcomes), patient reported outcome measures (PROMS) and X-ray measurement, electromyography both pre- and post-operatively.

Primary Outcome Measures
NameTimeMethod
Changes in patients reported outcomes - DASH (Disabilities of Arm, Shoulder and Hand)at baseline, 6 weeks and 6 months postoperatively

To measure overall disabilities of upper limb. Results range from 0 to 100, with lower scores corresponding to better outcomes.

Secondary Outcome Measures
NameTimeMethod
Changes in patients reported outcomes - SF-36 (Short Form 36)at baseline, 6 weeks and 6 months postoperatively

To explore differences in quality of life. Results range from 0 to 100, with higher scores corresponding to better outcomes.

Changes in carpometacarpal, carpophalangeal and wrist range of motionat baseline, 6 weeks and 6 months postoperatively

To explore differences in range of motion. This parameter will be measured with goniometer in flexion, extension, adduction and abduction in all thumb joints. Outcomes would be numers of degrees ranging from 0-360, with higher number corresponding with better outcomes

Changes in patients reported outcomes - PRWE (Patient Related Wrist Evaluation)at baseline, 6 weeks and 6 months postoperatively

To measure wrist pain and disability in activities of daily living. Results range from 0 to 50, with lower scores corresponding to better outcomes.

Changes in patients reported outcome measures - VAS (Visual Analogue Score)at baseline, 6 weeks and 6 months postoperatively

To explore differences in pain. Results range from 0 to 100, with lower scores corresponding to better outcomes.

Arthroplasty revision surgeriesat baseline, 6 weeks and 6 months postoperatively

To count and asses the reason of all revision surgeries that may occur during postoperative period

Changes in usage of painkillersat baseline, 6 weeks and 6 months postoperatively

To asses evolution of post-operative thumb pain. Dosage, frequency of utilisation and type of medicines will be measured in self-designed questionnaire, with lower dosage, lower frequency and less powerful medicines corresponding with better results

Operation related complicationsat baseline, 6 weeks and 6 months postoperatively

To count and asses all complications that may occur during surgery and in postoperative period

Biomechanical 3D motion analysisat baseline, 6 weeks and 6 months postoperatively

Movements in whole range are measured using 3D motion analysis, using a special software. With more physiological movement patterns corresponding with better results

Radiological outcome on x-raysat baseline, 6 weeks and 6 months postoperatively

To asses any changes in alignment of implants with would be measured with degrees (angles) with more degrees of change after operation corresponding with worse outcome

Muscle strength outcomesat baseline, 6 weeks and 6 months postoperatively

Muscle strength during grip measured using maximal voluntary isometric contraction (MVIC)

Changes in patients reported outcomes - Michigan Hand Outcomes Questionaireat baseline, 6 weeks and 6 months postoperatively

To explore differences in higher levels of activity at work and social participation. Results range from 0 to 100, with higher scores corresponding to better outcomes.

EMG measured bioelectrical potentialsat baseline, 6 weeks and 6 months postoperatively

Percutaneus electromyography (EMG) will be performed to measure bioelectrical potentials of thumb muscles, to assess ability to contracture
