Thomas's splint with adjustable ring.

Area of Science:

• Veterinary Orthopedics
• Biomedical Engineering

Background:

• Traditional Thomas splints may require modification to accommodate thigh swelling.
• Improper fit can lead to pressure sores and necessitate adjustments.

Purpose of the Study:

• To describe an adjustable ring modification for the Thomas splint.
• To improve patient comfort and reduce complications associated with splint use.

Main Methods:

• Incorporation of a stainless steel hose clip for adjustable ring diameter (5 or 7.5 cm).
• Addition of a hinge on the medial aspect of the anterior ring half.
• Allows for widening or tightening of the ring based on thigh circumference changes.

Main Results:

• The adjustable ring effectively accommodates thigh swelling and subsequent reduction.
• Maintained an exact fit, preventing slippage or excessive pressure.
• Eliminated the need to cut the splint ring to relieve pressure.

Conclusions:

• The adjustable ring Thomas splint provides a superior fit and enhanced comfort.
• This modification effectively prevents pressure sores and reduces the need for splint alteration.
• Offers a practical solution for managing dynamic limb volume changes in orthopedic bracing.
