Function Following Thumb MP Fusion and IP Fusion

Not Applicable

Completed

• Conditions: Osteoarthritis
• Interventions: Diagnostic Test: Jebsen Taylor Hand function test; Diagnostic Test: Pinch strength; Diagnostic Test: Grooved pegboard test

• Registration Number: NCT03661281
• Lead Sponsor: NYU Langone Health

Brief Summary

This study is to determine function following simulated thumb metacarpophalangeal (MP) and thumb interphalangeal (IP) joint fusion. The investigators want to determine the functional limitation created by MP and IP joint fusion. 20-30 volunteers will be fitted for custom molded orthoplast splints immobilizing either the MP or IP joint. The volunteers will then be taken through multiple tests including lateral pinch strength, tip pinch, grip strength, grooved pegboard test time, and Jebson Taylor test. Each patient will be tested without a splint, with their MP joint immobilized and with their IP joint immobilized. The results of this study can be used for patient education before surgery in order to help them make informed decisions as well as manage expectations. It can also serve as a decision aid in pinch restoration in the context of ulnar nerve palsy.

Arm && Interventions

Group	Intervention	Description
Simulated Thumb Arthrodesis	Pinch strength	Subjects will have their thumb immobilized in 2 prefabricated wrist splints to simulate 2 different fusion positions tested: one splint to simulate the MCP fusion and one to represent the IP fusion. Patients will complete hand function tests in each of the splints to evaluate hand function.
Simulated Thumb Arthrodesis	Jebsen Taylor Hand function test	Subjects will have their thumb immobilized in 2 prefabricated wrist splints to simulate 2 different fusion positions tested: one splint to simulate the MCP fusion and one to represent the IP fusion. Patients will complete hand function tests in each of the splints to evaluate hand function.
Simulated Thumb Arthrodesis	Grooved pegboard test	Subjects will have their thumb immobilized in 2 prefabricated wrist splints to simulate 2 different fusion positions tested: one splint to simulate the MCP fusion and one to represent the IP fusion.

Primary Outcome Measures

Name	Time	Method
Jebsen Taylor hand function test	1 Month	This consists of seven test items, which are felt to represent various hand activities. Each activity will be timed.
