Which condition is treated with long arm splinting at night to prevent elbow flexion?

Long arm splinting at night to prevent elbow flexion is particularly applicable in the case of cubital tunnel syndrome. This condition involves the ulnar nerve, which can become compressed or irritated at the elbow, often leading to symptoms such as pain, tingling, and weakness in the hand and fingers.

By using a long arm splint, the therapy aims to keep the elbow in an extended position during nighttime. This positioning helps alleviate pressure on the ulnar nerve and prevents exacerbation of symptoms that may occur during flexion when the nerve is more susceptible to compression.

In contrast, the other conditions mentioned do not typically require long arm splinting specifically for elbow flexion prevention. Carpal tunnel syndrome primarily affects the wrist, while rotator cuff syndrome involves shoulder structures, and tendonitis could affect various areas depending on the tendon involved, but these do not specifically relate to preventing elbow flexion in the same manner as cubital tunnel syndrome does. Thus, the use of a long arm splint is a targeted intervention for managing the symptoms associated with cubital tunnel syndrome effectively.
