“…15,17 Richardson et al 17 suggested that external compression at the elbow is a more important cause of UNE among women than men. Matev 15 recently reported that, in men, the ulnar nerve is more mobile and therefore more sensitive to gliding impairment at the medial epicondyle.…”

Short‐segment nerve conduction studies in ulnar neuropathy at the elbow

The aim of the study was to assess the diagnostic value of short-segment nerve conduction studies (NCS) at 2-cm intervals from 4 cm above to 4 cm below the medial epicondyle in a large group of patients with ulnar neuropathy at the elbow (UNE). Furthermore, we wanted to compare electrodiagnostic and clinical findings. We evaluated 73 arms in 70 patients with UNE and observed the following abnormalities on short-segment NCS: focal conduction block (CB) in 1, focal CB with increased latency change in 34, and increased latency change alone in 25. Short-segment NCS had an additional localizing value in 28 arms of the 37 patients (76%) with motor conduction velocity (MCV) slowing across the elbow only or with nonlocalizing electrodiagnostic findings. The lesion was located above the elbow in 32 arms (53%), at the epicondyle in 16 arms (27%), and below the epicondyle in 12 (20%) of the 60 arms with focal CB or increased latency change on short-segment NCS. Patients with CB on routine and short-segment NCS had muscle weakness significantly more often than patients without CB. Thus, short-segment NCS are useful in localizing the lesion in patients with UNE and CB on routine NCS and have additional diagnostic value in patients with MCV slowing across the elbow or with nonlocalizing signs on routine nerve conduction studies. We recommend its use in all patients in whom UNE is suspected.

“…It is unclear how the observed prevalence may have changed with survey of a cohort more reflective of the whole U.S. population. Because previous studies have suggested male sex and occupational activities (e.g., manual labor jobs, repetitive elbow motion) to be risk factors for cubital tunnel syndrome, the underrepresentation of these groups in our cohort [27][28][29] may have led to a relative underestimation of disease burden in comparison with a true representative population. We enrolled 74% of subjects who started the survey.…”

Objectives:Simple decompression is an accepted surgical treatment of ulnar nerve entrapment at the elbow (UNE). Our purpose was to evaluate the outcome and potential predictors for the outcome after simple decompression in UNE. Methods: All surgically treated UNE cases (from 2004-2008) at our department were studied retrospectively. Out of 285 primary surgeries, 242 primary simple ulnar nerve decompressions were included. Medical records, including electrophysiologic protocols, were reviewed and postoperative outcome was graded: 1) cured/improved and 2) unchanged/worsened symptoms, based on surgeon-evaluated outcome. Results: Of the 242 simple decompressions (122 males and 120 females; median age 50.5 years), 101 cases were students, retired, un-employed, or on a long-term sick-leave and 112 had manual, blue-collar type of work. 189 cases were cured or improved, while 53 cases had no change in, or even worsened, symptoms. Gender, presence of smoking, or associated diseases did not affect outcome, while a tendency was observed for higher age, a manual occupation and constant symptoms. Out of 196 cases electrophysiologically examined, 155 cases showed signs of ulnar nerve affection (56 reduced conduction velocity; 19 conduction block; 80 axonal degeneration; latter two groups significantly worse outcome). Conclusion: Patients with a preoperatively electrophysiologically diagnosed nerve conduction block or axonal degeneration have higher risk of not being cured or improved after simple decompression in UNE. Older patients, those with a manual profession, and constant symptoms of UNE tend to be less improved after surgery.
