A lesser degree of compression is unmasked by ‘freezing’ (ethyl chloride spray) the elbow, with subsequent positive scratch collapse test at the wrist. Sensation in the deep peroneal nerve distribution on the dorsum of the foot was also tested. We have previously described the Scratch Collapse Test (SCT) as a provocative test to assist in the clinical evaluation of patients with ulnar nerve symptomatology [ 2 , 3 ]. The scratch collapse test with ethyl chloride revealed provocation, first at the CPN at the fibular head, then second at the saphenous nerve in the thigh, and then third at the superficial peroneal nerve. Provocative testing by the scratch collapse test and Tinel's sign was performed. The scratch collapse test with ethyl chloride revealed provocation, first at the common peroneal nerve at the fibular head, then second at the saphenous nerve in the thigh, and then third at the SPN. Her surgical management included the release of these three nerves. The diagnosis was confirmed by history, physical examination, and electrodiagnostic testing. The diagnosis was based on the patient’s symptoms and signs. The patient then performs resisted shoulder external rotation. To perform the test, the examiner lightly scratches the patient’s skin over the area of suspected peripheral nerve compression. METHODS: The scratch collapse test was studied prospectively in 24 consecutive patients with a diagnosis of common peroneal nerve compression neuropathy. It is difficult for the student of peripheral nerve surgery to select a procedure for a specific patient based on these reports alone. It is difficult for the student of peripheral nerve surgery to select a procedure for a specific patient based on these reports alone. CONCLUSION: The scratch collapse test is a sensitive and specific provocative test that compares favorably to existing clinical tests and aids in the diagnosis of common peroneal neuropathy. The nerve injury type dictates the treatment and prognosis. A positive test was noted by ipsi-lateral weakness of resisted external rotation and collapse of the arm inward.
