A night elbow splint that maintains the elbow in a neutral or slightly extended position (around 30-45 degrees) is recommended for managing ulnar nerve compression at bedtime. This type of splint, often called an ulnar nerve compression splint or cubital tunnel splint, prevents prolonged elbow flexion during sleep which can exacerbate pressure on the ulnar nerve. The splint should be worn consistently every night for at least 3-6 weeks to evaluate effectiveness, though some patients may need longer treatment periods. When selecting a splint, look for one with adequate padding around the elbow region and adjustable straps to ensure proper fit and comfort.
The most recent and highest quality study, 1, a systematic review and meta-analysis published in 2023, found that splinting is a highly effective conservative management option for ulnar nerve compression at the elbow, with an improvement rate of 89%. This study supports the use of a night elbow splint as a first-line treatment for managing ulnar nerve compression.
Key considerations when using a night elbow splint include:
- Maintaining the elbow in a neutral or slightly extended position
- Wearing the splint consistently every night for at least 3-6 weeks
- Selecting a splint with adequate padding and adjustable straps
- Using the splint in conjunction with daytime modifications, such as avoiding prolonged elbow flexion and direct pressure on the elbow
By following these guidelines and using a night elbow splint, patients can effectively manage ulnar nerve compression and reduce symptoms like numbness, tingling, or pain in the ring and little fingers.
