In this study, investigators aimed to investigate the morphometric parameters tenar muscles and joint configuration in patients with trapeziometacarpal osteoarthritis (TMC OA) osteoarthritis stages, thenar muscle parameters, radial subluxation rate, functional level and hand dexterity.
Patients diagnosed with trapeziometacarpal osteoarthritis and healthy subjects will be included in the study. Thickness and cross-sectional area measurements of the thenar muscles of the patient and healthy volunteers will be performed by using Shimadzu SDU 1200-Pro ultrasound system with an 8-10 MHz linear probe. To improve the image quality and to avoid muscle compression, water immersion ultrasonography will be preferred and the hands will be positioned in a water-filled plastic container. The thenar muscles will be imaged in hands of each subject. In this study, poster-anterior radiographic imaging will be performed. The osteoarthritis stage will be determined on the radiographic image. Three different measurements will be performed on radiography: radial subluxation of the first metacarpal base (RS), articular width (AW) of the first metacarpal, and the distance between the ulnar articular facet of the trapezium and the ulnar edge of the metacarpal (U). RS / AW ratio will be calculated. Because TMC OA caused pain and affect performance, especially during grip activities in the osteoarthritis and control groups will be tested. Grip strength will also be measured.

Ultrasound-based muscle cross-sectional area of thenar muscles in this study will investigate in TMC OA patients and healthy subjects.
USG procedures will performed on patients with TMC OA and healthy volunteers. Cross-sectional area measurements of thenar muscles of patient and healthy volunteers will performed using a Shimadzu SDU 1200-Pro ultrasound system with 8-10 MHz linear probe. USG device will calibrated prior to the study. Water bath technique for USG evaluation will preferred in order to improve the image quality and to avoid muscle compression. The hands will positioned in a 60x50x40 cm water-filled plastic container. Five thenar muscles will imaged in the hands of each subject: Opponens pollicis, abductor pollicis brevis, flexor pollicis brevis, first dorsal inteosseous and adductor pollicis muscles. Images will acquired in the cross-sectional planes. 2 evaluators blinded to each other will measure 15 minutes apart. With the first evaluator, it will measure for the second and third times at 30-minute intervals from the first measurement.
Time frame: through study completion, an average of 1 year

The radial subluxation rate of the first metacarpal.
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
In this study, while PA radiographic imaging will performed, the elbows will ppositioned in 90 ° flexion, wrists in neutral position, MCP joints at 15-20 ° flexion and nails parallel to each other. During the scanning, patient will toush his thumbs together with maximum force. Three different measurements will made: the radial subluxation (RS) of the first metacarpal base, the articular width of the first metacarpal (AG), and the distance between the ulnar articular facet of the trapezium and the ulnar edge of the metacarpal (U) in milimeter will measured. RS/AG rate will calculated.

Evaluation of functional status of hand
Disability of Arm Shoulder and Hand (DASH) will used to determine functional status of hand.The total score is 100, and higher scores indicate a worse functional level.
Time frame: through study completion, an average of 1 year
Grip strength measurement
The grip strength will be measured in kilograms using a Jamar Hand Dynamometer
Time frame: through study completion, an average of 1 year
Evaluation of functional status of hand
Michigan Hand Outcomes Questionnaire (MHQ) includes 6 subtitles, namely general hand function, ADL, pain, work, aesthetics and satisfaction, and these headings are filled in for theight and left hand. Score calculation for each title is calculated separately. The total score is 100, high scores mean better functional status.
Time frame: through study completion, an average of 1 year
Pain Assessment
Pain intensity was evaluated using the visual analog scale (Visual Analogue Scale, VAS). The patients were told that the number "0" means "no pain" and "10" means "unbearable pain" on a 10 cm horizontal line. Patients were asked to mark the severity of pain during rest and activity on this line. The marked place was measured and the result was recorded as the intensity of pain in cm.
Time frame: through study completion, an average of 1 year
Pinch strength measurement
The pinch strength will be measured in kilograms using a Pinchmeter.

Minnesota hand skill test
Hand skills are evaluated in two different ways, namely placing the discs in their slots and rotating them. People are told that this test is a performance test and they are asked to complete the test as soon as possible. In the insertion part of the test, the patient is asked to take the discs one by one using one hand and put them in the appropriate slots respectively. In the rotating part of the test, the patient is asked to move the discs placed in their nests by rotating the discs in the upper right corner towards the left row. Both tests are repeated 3 times and the result is recorded in seconds.
Time frame: through study completion, an average of 1 year
9 Hole hand skill test
This test, which is used to evaluate fine hand skills, is carried out by taking 9 pins from the ground and placing them in the holes and removing them. The test time is approximately 10 minutes. After the patient is told that the test is a performance test and that it will be timed, he is asked to insert the pins first and then remove them as soon as possible. The test is performed twice consecutively on both hands and the two attempts are averaged, the results are recorded in seconds.
