De Quervain's Tenosynovitis in Primary Caregivers

Area of Science:

• Orthopedics
• Reproductive Medicine
• Occupational Health

Background:

• De Quervain's tenosynovitis is a common condition affecting the tendons on the thumb side of the wrist.
• Newborn caregiving involves repetitive motions that may contribute to wrist pain.
• Factors like child's age, weight, and lactation status are potential contributors.

Purpose of the Study:

• To determine the incidence of de Quervain's tenosynovitis in male and female newborn caregivers.
• To identify associated factors, including child's age, weight, and lactation status.

Main Methods:

• Surveys were administered to parents of young children in the Buffalo, NY area.
• Participants reported wrist pain, caregiving hours, child's age, and lactation status.
• Wrist pain sufferers performed a Finkelstein test and completed the QuickDASH questionnaire.

Main Results:

• 121 surveys returned; 20 reported wrist pain and a positive Finkelstein test (Group C).
• Group C had significantly higher QuickDASH scores than Group B (pain, negative Finkelstein).
• Child age was significantly different across pain groups, with the oldest children in Group C.

Conclusions:

• Mechanical aspects of newborn caregiving significantly contribute to postpartum de Quervain's tenosynovitis.
• Hormonal changes during lactation do not appear to be a major factor.
• Maintain a high index of suspicion for de Quervain's tenosynovitis in caregivers presenting with wrist pain.
