The Angle of the Metacarpophalangeal Joint of the Thumb During Maximal Pinch Strength

Not Applicable

Completed

• Conditions: Osteoarthritis Thumb; Post-traumatic; Arthrosis
• Interventions: Other: measurement of range of motion and strength

• Registration Number: NCT04875156
• Lead Sponsor: University Hospital, Ghent

Brief Summary

The aim of the study is to measure the position of the metacarpophalangeal joint of the thumb during key-pinch, tripod-pinch and opposition-pinch in normal volunteers, to determine the optimal position of metacarpophalangeal joint arthrodesis.

Detailed Description

The aim of the study is to measure the position of the metacarpophalangeal (MCP) joint of the thumb during key-pinch, tripod-pinch and opposition-pinch in normal volunteers, to determine the optimal position of metacarpophalangeal joint arthrodesis.

The force will be measured in three positions (key-pinch, tripod-pinch and opposition-pinch). Also measured is the degree of flexion of the MCP joint of the thumb. The mobility of the MCP joint of the thumb in maximum flexion and extension will also be measured. A total of about 300 healthy volunteers will be examined, with no history of trauma or disease to tendons or joints of the thumbs and between the ages of 18 and 40. The sponsor of this study is Professor Nadine Hollevoet. Master students of medicine from the faculty of medicine and health sciences will be part of the research team.
