[Ab] Resumo:This study aims to evaluate the value of electrophysiological examination and high frequency ultrasonography in the differential diagnosis of radial nerve torsion and radial nerve compression.Patients with radial nerve torsion (n = 14) and radial nerve compression (n = 14) were enrolled. The results of neurophysiological and high frequency ultrasonography were compared.Electrophysiological examination and high-frequency ultrasonography had a high diagnostic rate for both diseases with consistent results. Of the 28 patients, 23 were positive for electrophysiological examination, showing decreased amplitude and decreased conduction velocity of radial nerve; however, electrophysiological examination cannot distinguish torsion from compression. A total of 27 cases showed positive in ultrasound examinations among all 28 cases. On ultrasound images, the nerve was thinned at torsion site whereas thickened at the distal ends of torsion. The diameter and cross-sectional area of torsion or compression determined the nerve damage, and ultrasound could locate the nerve injury site and measure the length of the nerve.Electrophysiological examination and high-frequency ultrasonography can diagnose radial neuropathy, with electrophysiological examination reflecting the neurological function, and high-frequency ultrasound differentiating nerve torsion from compression.

[Ab] Resumo:Radial nerve palsies are a common complication associated with humeral shaft fractures. The authors propose classifying these injuries into 4 types based on intraoperative findings: type 1 stretch/neuropraxia, type 2 incarcerated, type 3 partial transection, and type 4 complete transection. The initial management of radial nerve palsies associated with closed fractures of the humerus remains a controversial topic, with early exploration reserved for open fractures, fractures that cannot achieve an adequate closed reduction requiring fracture repair, fractures with associated vascular injuries, and polytrauma patients. Outside of these recommendations, expectant observation for spontaneous recovery is recommended.

[Ab] Resumo:BACKGROUND: This article reports the operative technique and clinical effect of repairing thumb pulp defects using a modified first dorsal metacarpal artery flap method. In this method, the dorsal branches of the radial and ulnar proper digital nerves of the index finger were preserved but the superficial branches of the radial nerve were transected. METHODS: Data obtained from 121 patients with thumb pulp defects who were admitted to the authors' hospital from June of 2011 to December of 2014 were retrospectively analyzed. Patients were divided into two groups based on whether the superficial branches of the radial nerve were transected. The dorsal branches of the radial and ulnar proper digital nerves of the index finger and the proper digital nerves in the wound were coapted using the end-to-end style. Static two-point discrimination, Semmes-Weinstein monofilament scores, pain, cold intolerance of the reconstructed finger, allachesthesia, and patient satisfaction were compared between the two groups. RESULTS: The authors observed significant differences in static two-point discrimination, Semmes-Weinstein monofilament flap score, pain of finger pulp, allachesthesia duration, and patient satisfaction (p < 0.05). The transection group presented slightly better discriminatory sensation in the flap and higher patient satisfaction. In addition, the duration of allachesthesia in the transection group was significantly shorter than that in the preservation group. CONCLUSION: In the repair of thumb pulp defects using a modified first dorsal metacarpal artery flap carrying the dorsal branches of the radial and ulnar proper digital nerves of the index finger, transecting the superficial branches of the radial nerve achieved better clinical outcome compared with preserving them. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

[Ti] Título:Propriospinal cutaneous-induced EMG suppression is unaltered by anodal tDCS of healthy motor cortex.

[Ab] Resumo:OBJECTIVE: Cervical propriospinal premotoneurons (PN) relay descending motor commands and integrate peripheral afferent feedback. Effects of anodal transcranial direct current stimulation (a-tDCS) on propriospinal excitability in the upper limbs are unknown. METHODS: Healthy right-handed adults received a-tDCS or sham tDCS over primary motor cortex (M1) at 1mA (Experiment 1, n=18) or 2mA current intensity (Experiment 2, n=15). Propriospinal excitability was assessed by suppression of background electromyography (EMG) in extensor carpi radialis (ECR) from electrical stimulation of the superficial radial nerve during bilateral (Experiment 1 and 2) or unilateral (Experiment 2 only) activation of the left and/or right ECR. EMG suppression could be attributed to an early propriospinal component and late cortical component. Motor evoked potentials (MEP) were obtained as a manipulation check. RESULTS: Before tDCS, propriospinal-mediated cutaneous-induced suppression was present in each arm for early and late components. ECR MEP amplitude increased after 1mA, but not 2mA, a-tDCS. Neither 1mA nor 2mA a-tDCS modulated either component of ipsilateral or contralateral propriospinal excitability during bilateral or unilateral tasks. CONCLUSIONS: Propriospinal-mediated cutaneous-induced suppression was not modulated by a-tDCS in healthy adults. SIGNIFICANCE: Reporting non-significant findings is paramount for the development of clinically-relevant tDCS protocols.

[La] Idioma:eng
[Ab] Resumo:OBJECTIVE: This study aimed to examine the corticomotor excitability changes after peripheral nerve electrical stimulation (PNS) on the stroke-impaired arm. DESIGN: This randomized cross-over study included 32 subjects with chronic stroke. They received a 1-hr PNS or placebo PNS by random order to the ulnar and radial nerves of the paretic arm in separate sessions. The primary outcome was excitability of the corticospinal projections for the contralateral first dorsal interosseous hand muscle in terms of slope of the recruitment curve, peak motor-evoked potential amplitude, and duration of the cortical silent period, measured with transcranial magnetic stimulation on both cerebral hemispheres. Seventeen of the subjects were measured for their paretic hand dexterity (using Purdue Pegboard Test) and pinch strength as secondary outcomes. RESULTS: Peripheral nerve electrical stimulation, but not placebo PNS, increased recruitment curve slope and peak motor-evoked potential amplitude in both the lesioned and nonlesioned hemispheres and lengthened the cortical silent period duration in the nonlesioned hemisphere. Peripheral nerve electrical stimulation significantly improved hand dexterity scores compared with placebo PNS. Pinch strength was not changed by the interventions. CONCLUSIONS: A 1-hr PNS alone to the paretic arm could increase corticomotor excitability in both hemispheres, together with hand dexterity improvement in people presented with mild-to-moderate motor impairment in the paretic upper limb after stroke.

[Ab] Resumo:PURPOSE: To describe histologic evidence of nerve trauma during the creation and use of the 3-4 portal. METHODS: Fourteen fresh-frozen cadaveric wrists were mounted on a custom-built frame that simulated a wrist arthroscopy traction tower. After the 3-4 portal was created in the usual manner, the skin was dissected off to identify possible trauma to the posterior interosseous nerve (PIN). Specimens were categorized into those where there was clearly no trauma to the PIN and those where trauma was possible. In the cases where trauma was possible, we harvested the PIN with a cuff of the proximal edge of the portal and examined the cross-sectional histology of the most distal sections for the presence of neural tissue. RESULTS: There was clearly no trauma to the PIN in 3 of the wrists during the creation of the 3-4 portal. In the remaining 11 wrists with possible trauma to the PIN, we identified axonal tissue on histologic examination at the proximal edge of the 3-4 portal in 7 of these specimens. In summary, 50% (7 of 14) of our specimens had visual and histologic evidence of trauma to the PIN. CONCLUSIONS: Based on the findings of this study, there may be more instances of trauma to the PIN during routine wrist arthroscopy than have been previously reported. CLINICAL RELEVANCE: Findings suggest that transection or injury to this nerve may not lead to any clinical sequelae. However, if there is an instance where a patient has persistent, otherwise unexplained, dorsal wrist pain after a wrist arthroscopy procedure, iatrogenic neuroma of the PIN may be responsible and should be considered.

[Ti] Título:Predictors of radial nerve palsy recovery in humeral shaft fractures: A retrospective review of 17 patients.

[La] Idioma:eng
[Ab] Resumo:BACKGROUND: Radial nerve injury is common in humeral shaft fractures and fails to recover spontaneously in 30% of cases. Few studies have evaluated predictors of recovery. The objectives of this study were to identify predictors of radial nerve palsy recovery and to assess the usefulness of surgical radial nerve exploration in patients with preoperative radial nerve palsy. HYPOTHESIS: Factors predicting the outcome of radial nerve palsy can be identified. METHODS: Of 373 patients with humeral shaft fractures between 2005 and 2012, 43 had radial nerve palsy, including 23 who were lost to follow-up and 17 who were evaluated retrospectively at a mean of 26 months (range, 12-84 months) after internal fixation. The following were studied: age, smoking history, energy of the trauma, fracture type and displacement, skin integrity and intra-operative appearance of the radial nerve. RESULTS: Of the 17 palsies, 13 were present preoperatively, including 10 that recovered (PreR group) and 3 that did not recover (PreNR group). Plate fixation and radial nerve exploration were performed in all patients. Of the 10 PreR patients, 6 had nerve contusion and 2-nerve entrapment. Of the 3 PreNR patients, 2 had gross nerve damage and 1 nerve contusion and a history of spinal muscular atrophy. Only age and presence of gross nerve damage differed significantly between the PreR and PreNR groups; trends towards significant differences were noted for skin breach and fracture displacement. Of the 4 postoperative radial nerve palsies, 2 recovered fully and 2 partially; mean age was higher in the 2 patients with partial recovery. DISCUSSION: These findings are consistent with the few previous studies of outcome predictors in radial nerve palsy. Factors such as major fracture displacement and high-grade skin wounds probably promote the occurrence of gross nerve lesions. The high incidence of nerve entrapment and stretching supports routine nerve exploration during internal fixation in patients with preoperative radial nerve palsy. LEVEL OF EVIDENCE: IV, retrospective study with no control group.

[Ab] Resumo:INTRODUCTION: In this study we provide detailed quantification of upper extremity nerve and fascicular anatomy. The purpose is to provide values and trends in neural features useful for clinical applications and neural interface device design. METHODS: Nerve cross-sections were taken from 4 ulnar, 4 median, and 3 radial nerves from 5 arms of 3 human cadavers. Quantified nerve features included cross-sectional area, minor diameter, and major diameter. Fascicular features analyzed included count, perimeter, area, and position. RESULTS: Mean fascicular diameters were 0.57 ± 0.39, 0.6 ± 0.3, 0.5 ± 0.26 mm in the upper arm and 0.38 ± 0.18, 0.47 ± 0.18, 0.4 ± 0.27 mm in the forearm of ulnar, median, and radial nerves, respectively. Mean fascicular diameters were inversely proportional to fascicle count. CONCLUSION: Detailed quantitative anatomy of upper extremity nerves is a resource for design of neural electrodes, guidance in extraneural procedures, and improved neurosurgical planning.

[Ti] Título:Variations in the Innervation of the Long Head of the Triceps Brachii: A Cadaveric Investigation.

[Ab] Resumo:BACKGROUND: Some leading anatomy texts state that all three heads of the triceps brachii are innervated by the radial nerve. The posterior cord of the brachial plexus bifurcates to terminate as the radial and axillary nerves. Studies have noted the presence of axillary innervation to the long head of the triceps brachii muscle, patterns different from the classic exclusive radial nerve supply. An understanding of these variations may assist the clinician in the assessment of shoulder weakness and in preoperative and operative planning of radial and axillary neuropathies. QUESTIONS/PURPOSE: We aimed to further investigate, in cadaver dissections, the prevalence of axillary nerve contribution to the innervation of the long head of the triceps brachii. METHODS: We performed bilateral brachial plexus dissections on 10 embalmed cadavers combining anterior axillary and posterior subscapular approaches. Two additional unilateral cadaveric brachial plexuses were dissected. The posterior cords were fully dissected from the roots distally. The radial and axillary nerves were followed to their muscle insertion points, the dissections were photographed, and the length of branching segments were measured. RESULTS: Of the 10 paired cadavers dissected (20 specimens), in only one of the 10 cadavers was the classic innervation pattern of radial nerve observed. The other nine cadavers had varying patterns of radial and axillary nerve innervation, The observed patterns were radial and axillary (dual) on one side with radial alone on the other, dual innervation bilaterally, or axillary with contralateral radial innervation. The two additional unilateral dissected specimens were innervated exclusively by the axillary nerve. CONCLUSIONS: Gross and surgical anatomy sources state that the radial nerve is the sole nerve supply to the long head of the triceps. In our study sample, pure radial innervation of the long head of the triceps brachii was not the predominant nerve pattern. We found four other studies that looked at axillary innervation of the long head of the triceps; of the 62 total cadaver shoulders examined in those studies, 71% were found to have nonclassic innervation patterns. Nonclassic patterns may include purely axillary, dual, or posterior cord innervation to the long head of the triceps, and may account for the majority of innervation to the long head of the triceps. These are similar to our findings. CLINICAL RELEVANCE: Understanding the innervation of the long head of the triceps and variations in axillary nerve course is critical to the clinical diagnosis of injury, surgical treatment options, and rehabilitation of axillary nerve injuries. With this information, the practitioner may have additional surgical options, clearer rationales for clinical situations, and explanations for patient outcomes.

[Ab] Resumo:In approximately 4-13 % of cases plating of the humerus for stabilizing a shaft fracture is complicated by a secondary lesion of the radial nerve. In the majority of cases this is due to intraoperative traction on the nerve. The compression of a radial nerve under an osteosynthesis plate is reported only rarely. This article presents the case of a spontaneous regeneration of a radial nerve despite ongoing compression by the surgical implant after compression plating of a humeral shaft fracture. Recommendations are given to avoid such an iatrogenic lesion of the radial nerve, which most commonly is not spontaneously reversible.
