Compression peroneal neuropathy following a bicycle injury in a child. Reprinted with permission [14]. The scratch collapse test in the diagnosis of compression of the median nerve in the proximal forearm. See the patient example video. Provocative testing by the scratch collapse test and Tinel's sign was performed. The purpose of this study is to introduce the hierarchical SCT as a physical examination tool for identifying multilevel nerve compression in patients with cubital tunnel syndrome. RESULTS: The scratch collapse test showed a sensitivity of 0.77 and a specificity of 0.99, while the Tinel's sign showed 0.65 and 0.99, respectively. The diagnosis was confirmed by history, physical examination, and electrodiagnostic testing. METHODS: The scratch collapse test was studied prospectively in 24 consecutive patients with a diagnosis of common peroneal nerve compression neuropathy. Adjunct maneuvers--add ‘freezing’ to fetter out a second downstream level of nerve compression: • For example, in ulnar nerve compression at both the elbow (primarily) and the wrist (secondarily), you may want to operate on both at the same time so that you do not have to return for a second procedure, as relatively little risk or additional downtime is added with the relatively minor wrist-level procedure. Gillenwater et al described the scratch collapse test being a sensitive and specific provocative test that compares favorably to existing clinical tests and aids in the diagnosis of common peroneal neuropathy [5]. Our purpose was to review the clinical usefulness of the scratch collapse test (SCT) in the diagnosis of proximal entrapment of the median nerve in the forearm. AB - BACKGROUND: The scratch collapse test is a recently described provocative test for diagnosis of peripheral nerve compression. sation. • ‘Sensation of tingling’ or ‘pins and needles’, felt at the lesion site or more distally along the course of a nerve … MRI showed no pathology and the EMG was unspecific.

Scratch-collapse may be positive at the elbow, but negative at the wrist. BACKGROUND: The scratch collapse test is a recently described provocative test for diagnosis of peripheral nerve compression. Common peroneal nerve dysfunction is a type of peripheral neuropathy (damage to nerves outside the brain or spinal cord). This study aims to perform a systematic review of literature to assess the data on the reliability of the SCT as a diagnostic test for entrapment neuropathy. Directly over the suspected nerve compression, the examiner gently scratches the skin. Tinel’s sign-- one of the most important physical exam maneuvers in peripheral nerve injury evaluation.

Nerve Repair and Reconstruction—Peroneal Nerve Shawn Moshrefi Catherine Curtin DEFINITION Peroneal Nerve Injury Peroneal nerve injuries vary in severity, mechanism, and needed treatment. The utility of the scratch collapse test has been demonstrated in examination of patients with carpal and cubital tunnel syndromes and long thoracic and peroneal nerve compressions. The scratch collapse test, which entails firm scratching over the tarsal tunnel followed by resisted external rotation of the arm, revealed loss of ipsilateral arm strength. RESULTS: The scratch collapse test showed a sensitivity of 0.77 and a specificity of 0.99, while the Tinel's sign showed 0.65 and 0.99, respectively. Reprinted with permission [14].

Our purpose was to review the clinical usefulness of the scratch collapse test (SCT) in the diagnosis of proximal entrapment of the median nerve in the forearm. 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. Our purpose was to review the clinical usefulness of the scratch collapse test (SCT) in the diagnosis of proximal entrapment of the median nerve in the forearm. A positive test was noted by ipsi-lateral weakness of resisted external rotation and collapse of the arm inward. 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. It is difficult for the student of peripheral nerve surgery to select a procedure for a specific patient based on these reports alone. The patient then performs resisted shoulder external rotation.

Nerve compression was evaluated with the Tinel test and the scratch-collapse test. Scratch collapse test 4 This test can identify site of nerve entrapment. Sitemap| Peroneal nerve entrapment caused by compression at the fibular head was assessed by asking about pain at the fibular head, by using the Tinel sign, 16,17 and by manual muscle force testing. It can provide one more clue or confirmation of the level of nerve injury, in addition to providing insight to the hierarchy of nerve injuries within multiple levels. The peroneal nerve is a branch of the sciatic nerve, which supplies movement and sensation to the lower leg, foot and toes.

The scratch-collapse test has been shown to be a useful tool for identifying areas of nerve compression and can be used to identify multiple areas of compression in patients with complicated nerve pain. Peripheral nerve entrapment can give rise to hyperalgesia and allodynia. Three segments of possible entrapment tested in current study: (A) Proximal segment corresponds to area of the distal arcade of Struthers (regions 1 and 2); (B) Middle segment overlies cubital retinaculum (regions 3 and 4; C) Distal segment in area of Osborne’s band (regions 5 and 6). Common peroneal nerve decompression at the fibular neck. METHODS: The scratch collapse test was studied prospectively in 24 consecutive patients with a diagnosis of common peroneal nerve compression neuropathy. The ‘Scratch Collapse Test’ (SCT) has emerged as a new provocative test to assist in the localisation of peripheral nerve compression. Originally developed by Susan Mackinnon, it is performed by applying a stimulus over an area of nerve compression while the patient is exerting bilateral external shoulder rotation.

The scratch collapse test (SCT) is a relatively new clinical test in which a positive result implies entrapment neuropathy of the nerve tested. It is difficult for the student of peripheral nerve surgery to select a procedure for a specific patient based on these reports alone. The original search terms included “scratch collapse test” and “carpal tunnel syndrome” or “median nerve entrapment”; however, articles were missed with these search terms; therefore, the authors performed a broader search using only “scratch collapse test” to ensure articles were not overlooked. The diagnosis was confirmed by history, physical examination, and electrodiagnostic testing. • Patient seated/standing, arms at sides with elbows flexed to 90°, wrists at neutral and fingers extended.
