What is evaluated when testing for Scaphoid Instability?

When testing for Scaphoid Instability, the focus is on identifying symptoms that are characteristic of this condition, which often presents with pain or audible noises during specific wrist movements. This instability typically results from injury to the scaphoid bone or the surrounding ligaments, leading to abnormal motion between the carpal bones.

During the evaluation, clinicians look for symptoms such as crepitus or pain when the wrist is moved into certain positions, indicating that the scaphoid is not functioning correctly within the carpal chain. This is essential for diagnosing scaphoid instability, as these signs can help differentiate it from other wrist injuries.

In contrast, evaluating for paresthesia in the hand typically relates to nerve issues rather than instability of the scaphoid. Measuring the flexion of the distal phalanx focuses on the fingers rather than the carpal bones and does not directly assess wrist stability. The angle of cervical flexion pertains to the neck rather than the wrist. Thus, the assessment of noise or pain during specific wrist movements directly correlates to the evaluation of scaphoid instability.
