Filter by:Ulnar neuropathy at the elbow (UNE) is the second most common neuropathy and occurs after recurrent or elongated elbow flexion. Diagnosis of UNE depends on clinical symptoms, physical examination, and electrophysiological findings. Imaging methods such as ultrasonography (USG) and magnetic resonance imaging show cross-sectional area and echogenicity of ulnar nerve and give information about to surrounding structures around the ulnar nerve. In mild and moderate cases, conservative treatments are administered up to 6 months, who do not benefit from conservative treatment are referred to surgery. There are not many options for conservative treatment. Activity modification, nerve gliding exercises and night splints are conservative treatment methods. Steroid injection is no longer recommended. Perineural dextrose injection is applied in tendinopathies and entrapment neuropathies (especially carpal tunnel syndrome). In the literature, there is no study showing effect of perineural dextrose injection in patients with UNE. The investigators design a randomized, double-blind, controlled trail to evaluate the effect after ultrasound-guided perineural injection with 5% dextrose in patients with UNE.
The purpose of the study is to investigate utility and appropriateness of treatment interventions taking into account the presumed mechanisms of two main varieties of ulnar neuropathy at the elbow (UNE). The investigators hypothesize that in patients with UNE under the humeroulnar aponeurosis (HUA) surgical HUA release (simple decompression) is superior to conservative treatment. By contrast, in patients with UNE at the retroepicondylar (RTC) groove surgical HUA release (simple decompression) should not be superior to conservative treatment.
There is currently no consensus on the normal ultrasound surface of the ulnar nerve at the elbow. The goal of this study is to study the ulnar nerve surface at the elbow in a population of asymptomatic subjects
Ulnar neuropathy at elbow (UNE) is the second common peripheral entrapment neuropathy. Although many conservative managements of UNE, the effectiveness of these methods are unsatisfied especial the moderate degree of UNE. Recently, ultrasound-guided perineural injection therapy (PIT) with 5% dextrose is progressively applicated for clinical treatment for entrapment neuropathy. However, current studies have not proved the effects of PIT on peripheral neuropathy because these studies enrolled small number of patients and lacked controlled design. We design a randomized, double-blind, controlled trail to assess the effect after ultrasound-guided PIT with 5% dextrose in patients with mild and moderate UNE.
This study is to investigate the incidence of undiagnosed ulnar neuropathy in patients undergoing surgery. The investigators hope to determine if patients with ulnar neuropathy have changes in nerve conduction latency during surgery.
Ulnar nerve compression at the elbow is a common problem and can significantly affect hand function in severe cases. The current, standard treatment is Ulnar nerve decompression with or without transposition (moving the ulnar nerve to a site where there is less compression). In severe compression, the clinical results after this surgery are typically poor. Distal transfers of functioning nerves (at the level of the wrist) to the compressed ulnar nerve (anterior interosseous nerve to ulnar motor fascicles) have been suggested to "supercharge" or augment hand muscles while nerve axons regenerate from the level of the elbow after decompression/transposition. In fact, this treatment is becoming widely adopted without clear evidence that it changes outcomes. The investigators propose to prospectively compare the effectiveness of ulnar nerve decompression/transposition versus decompression/transposition and distal nerve transfer.
The purpose of this study is to determine if a new diagnostic technique, called neuromuscular ultrasound, can improve our ability to diagnose focal nerve disease.
Objectives: To develop a protocol for early treatment using sensory reeducation through the mirror after surgical reconstruction of the median nerve and / or ulnar hand, and its comparison with the evolution of the return of skin sensitivity after a not early rehabilitation which will be conducted by physiotherapists, with blinding of the evaluators.
