“…Osborne (1957, 19701, Feindel & Stratford (1958 and Apfelberg & Larson (1973) have reported that the space available to the ulnar nerve decreases when the elbow is flexed. In cadaver experiments, Pechan & Julis (1975) observed that the intraneural pressure in the ulnar nerve increased during elbow flexion, and our investigation confirmed this.…”

“…4. The leading edge of the cubital tunnel retinaculum can constrict the nerve as the elbow flexes and the aponeurotic fascia tightens [2,32]. Rarely, anconeus epitrochlearis muscle will exist at this site and can stenose the entrance to this tunnel causing compression [7,10].…”

The objective of this study is to demonstrate the utility of the scratch collapse test (SCT) in localizing the point of maximal compression in cubital tunnel syndrome. From January 1, 2004 to December 1, 2005, 64 adult patients with cubital tunnel syndrome were evaluated by a single surgeon. Cubital tunnel syndrome was diagnosed based upon symptoms of numbness, tingling, and/or pain in the ulnar nerve distribution or by the presence of weakness or wasting of the ulnar-innervated intrinsic hand muscles. All diagnoses were confirmed with electrodiagnostic studies. As part of the physical examination, the SCT was performed along three subdivided segments in the region of the cubital tunnel. Results of the SCT were recorded and correlated with intraoperative findings. Of the 64 patients evaluated, 44 had a positive SCT that was either more profound or solely present a few centimeters distal to the medial epicondyle in the region of Osborne's band. All of these patients subsequently underwent anterior submuscular transposition and were found to have a tight compression point at Osborne's band corresponding to their preoperative SCT. This study suggests that the scratch collapse test may be a reliable physical examination technique for localizing the point of maximal nerve compression in patients with cubital tunnel syndrome. That point, in this series, corresponded with Osborne's band.

“…It is thus, at this point, most prone to trauma or entrapment. Also when the elbow is flexed the tunnel is narrowed and the nerve compressed (Apfelberg & Larson, 1973).…”

Abstract. Twelve male patients with spinal cord injury were studied. The purpose of this study was to determine if ulnar nerve damage occurs in patients with spinal cord injury who are wheelchair bound and if so at which segment of the ulnar nerve.The results showed significant drop in ulnar nerve conduction velocity in both segments, mid-arm to below elbow and below elbow to the wrist. There was no significant difference between quadriplegic and paraplegic. No significant correlation was found between ulnar nerve impairment and the duration of spinal cord injury.
