Ulnar tunnel syndrome indicates ulnar neuropathy at different sites within the wrist. Several classifications of ulnar tunnel syndrome are present in literature, based upon typical nerve anatomy. However, anatomical variations are not uncommon and can complicate assessment. The etiology is also complex, due to the numerous potential causes of entrapment. Clinical examination, neurophysiological testing, and imaging are all used to support the diagnosis. At present, many therapeutic approaches are available, ranging from observation to surgical management...

RATIONALE: Cubital tunnel syndrome has been recognized as a common pathology in rheumatoid arthritis (RA) of the elbow. We encountered a patient with RA of the elbow showing attrition rupture of the ulnar nerve. This pathology is extremely rare, and we discussed preventive measures for similar cases in the future based on our case. PATIENT CONCERNS: A 53-year-old woman, received drug treatment for RA since 30 years earlier, had numbness in the left ulnar nerve territory, dorsal interossei muscle atrophy, and resulting claw hand...

BACKGROUND: Ulnar nerve transposition (UNT) surgery is performed for the treatment of cubital tunnel syndrome. Improperly performed UNT can create iatrogenic pain and neuropathy. The aim of this study is to identify anatomical structures distal to the medial epicondyle that should be recognized by all surgeons performing UNT to prevent postoperative neuropathy. METHODS: Ten cadaveric specimens were dissected with attention to the ulnar nerve. Intramuscular UNT surgery was simulated in each...

Lipomas are benign tumors that rarely settle in the hand. They usually present with mass, pain, and nerve compression symptoms. Although isolated median or ulnar nerve compression neuropathy secondary to a lipoma of the hand has been widely reported, simultaneous median and ulnar nerve compression neuropathy are exceedingly rare and there are only three reported cases in the current literature to date. Herein, a case of a 50-year-old woman with a giant palmar lipoma that caused median and ulnar compression neuropathy is presented...

BACKGROUND: Neopterin, a marker of inflammation and cellular immune response, is elevated in conditions of T-cell or macrophages activation. Diabetic peripheral neuropathy (DPN) is associated with inflammatory/immune processes and therefore, we hypothesized that neopterin could be used as a marker of neuropathy in type 1 diabetes mellitus (T1DM). AIM: To measure neopterin levels in children and adolescents with T1DM and assess its possible relation to DPN and nerve conduction studies (NCS)...

PURPOSE: Imaging criteria for diagnosing compressive ulnar neuropathy at the elbow (UNE) have recently been established as the maximum ulnar nerve cross-sectional area (UNCSA) upon magnetic resonance imaging (MRI) and/or ultrasonography (US). However, the levels of maximum UNCSA and diagnostic cutoff values have not yet been established. We therefore analyzed UNCSA by MRI and US in patients with UNE and in controls. METHODS: We measured UNCSA at 7 levels in 30 patients with UNE and 28 controls by MRI and at 15 levels in 12 patients with UNE and 24 controls by US...

BACKGROUND: Comparison of sensory conduction of median nerve (MN) with the one of ulnar nerve (UN) over writs-to-ring finger (RF) segment is useful in electrodiagnosis of carpal tunnel syndrome (CTS). However, there is not any consensus regarding the usage of this technique in grading of CTS. OBJECTIVES: To determine whether the hands of CTS with elicitable MN sensory responses on index finger, but not on RF (non-respondings) compose a more severe electrophysiologic grade than the hands with elicitable responses on both fingers (respondings)...

INTRODUCTION: Releasing the ulnar nerve from all entrapments is the primary objective of every surgical method in ulnar neuropathy at the elbow (UNE). The aim of this retrospective diagnostic study was to validate preoperative 3-Tesla MRI results by comparing the MRI findings with the intraoperative aspects during endoscopic-assisted or open surgery. METHODS: Preoperative MRI studies were assessed by a radiologist not informed about intraoperative findings in request for the exact site of nerve compression...

Background: Familial transthyretin amyloidosis is a life-threatening disease presenting with sensorimotor and autonomic polyneuropathy. Delayed diagnosis has a detrimental effect on treatment and prognosis. To facilitate diagnosis, we analyzed data patterns of patients with transthyretin familial amyloid polyneuropathy (TTR-FAP) and compared them to polyneuropathies of different etiology for clinical and electrophysiological discriminators. Methods: Twenty-four patients with TTR-FAP and 48 patients with diabetic polyneuropathy (dPNP) were investigated (neurological impairment score NIS; neurological disability score NDS) in a cross-sectional design...

BACKGROUND: The pathogenesis of secondary Raynaud's phenomenon (SRP) associated with connective tissue diseases (CTD) is not entirely understood. Nervous system dysfunction and microangiopathy are considered to be causes of this pathology. OBJECTIVES: Peripheral and autonomic nervous system function, the stage of microangiopathy, and the relationships between these in patients with SRP were analyzed. MATERIAL AND METHODS: In the study, 20 patients with CTD-related SRP and 30 healthy controls were subject to capillaroscopy, standard conduction velocity tests and conduction velocity distribution (CVD) tests in ulnar and peroneal nerves, heart rate variability (HRV), and sympathetic skin response (SSR) tests...

BACKGROUND: Open «arthrolysis» has been the standard treatment for elbow stiffness, with good results. However, the associated complications of open arthrolysis and the advancements in arthroscopic surgery have allowed including the latter as an additional approach. MATERIAL AND METHODS: Between January 2014 and March 2016, 6 patients with posttraumatic elbow stiffness underwent arthroscopic surgery by the same surgical team. Pre- and post-operative assessment included pain with a numerical visual analogue scale, elbow joint range of motion with a goniometer and the Mayo Elbow Performance Index questionnaire...

BACKGROUND: Although ulnar neuropathies are commonly encountered, isolated involvement of the motor branch is exceedingly rare. Previous reports of this entity describe compression as the deep motor branch passes through the piso-hamate hiatus and the adductor pollicis hiatus. This case series described 3 cases of motor branch compression due to unique etiologies which resolved after surgery. METHODS: A retrospective chart review identified patients with compression of the ulnar nerve motor branch...

BACKGROUND: Ulnar collateral ligament (UCL) reconstruction has become increasingly popular in elite athletes. However, the prevalence of heterotopic ossification (HO) formation after UCL reconstruction has not yet been reported. We sought to determine the prevalence of HO formation after UCL reconstruction and the clinical outcomes following HO treatment. MATERIALS AND METHODS: From October 2005 to April 2014, 179 patients underwent primary UCL reconstruction. Of the 179 patients, 161 with a minimum of 2 years of follow-up were retrospectively reviewed to evaluate HO formation and clinical outcomes...
