目的探讨颈后路单开门椎管扩大成形术与胶原酶直视下溶盘术联合治疗外伤性无骨折脱位型颈脊髓损伤的疗效。方法对11例外伤性无骨折脱位型颈脊髓损伤患者行颈后路单开门椎管扩大成形术,然后在直视下将胶原酶注入突出的颈椎间盘,术后平均随访时间为24个月,结合症状、体征、影像学资料,观察手术效果。结果联合治疗有效地缓解了患者的症状、体征。影像学资料显示椎管容积明显增加,突出的间盘缩小。术后6个月平均JOA改善率63.7%。结论联合治疗不仅通过后路单开门扩大了椎管的容积,而且通过溶盘术缓解了颈髓前面突出髓核的压迫,从而取得了较好的治疗效果。单开门椎管扩大成形术和胶原酶溶盘术联合治疗Ⅲ型无骨折脱位型颈脊髓损伤是一种可行的手术方法。 相似文献

Summary Regeneration of peripheral nerve fibers is impeded by the formation of scar tissue at the site of injury. The possible beneficial effect of collagenase on nerve regeneration was studied using clinical, neurophysiological (evoked potentials) and histological (nerve fiber counts) methods.The sciatic nerves of rats were transected and the severed ends abutted and sewn together. In one series, the area about the lesion was covered with fibrin adhesive and infused with either isotonic saline (controls) or collagenase (treatment group). In the other series, the severed ends of the nerve were inserted into a silicone tube and separated by a collagen plug, which was infused with either saline or collagenase. Compared to the controls, the treated animals showed a significant improvement of clinical and neurophysiological parameters. After 3 months of observation, the collagen content of the transection site was reduced, and in the silicone series, the total number of myelinated axons 5mm distal to the site of transection was increased, while the fiber diameter distribution was unchanged.Supported by a grant from the Deutsche Forschungsgemeinschaft (We 1248). 相似文献

Martin H. Chochole M.D. Wolfgang Senker M.D. Christian Meznik M.D. Martin J. Breitenseher M.D. 《Arthroscopy》1997,13(6):753-755
Glenoid labral cysts are commonly associated with labral tears, which can cause pain or instability. We present the case of a patient, referred for neurological complaints, who was actually suffering from supraspinatus nerve entrapment syndrome. Electroneurogram studies showed an isolated lesion of the branch to the infraspinatus muscle. Magnetic resonance imaging confirmed a glenoid labral cyst extending from the cranial glenoid to the scapular notch. After arthroscopic debridement of an extended SLAP-lesion that had caused joint fluid extrusion, the dissolution of the cyst was associated with complete neurological recovery. The patient is pain free and range of motion is normal. An attempt at an arthroscopic procedure seems warranted in cases like this, since cysts that accompany labral tears can dissolve after rigorous debridement of the torn labrum, much like meniscal cysts. Extended and hazardous open excisions can thus be avoided. 相似文献

Introduction
In the assessment of hand and upper limb function, grip strength is of major importance. Use of the JAMAR dynamometer has been an accepted test of grip strength and routinely part of the physical examination.Purpose of the Study
The aim of this study was to determine by means of a median nerve block simulating a patient group if the measurement of different types of grip force can improve the quantification of impairment of the hand beyond the sole power grip measurements.Methods
In 29 healthy volunteers, grip force measurement was done by the JAMAR dynamometer for power grip and by a pinch grip dynamometer for pincer grip, precision grip, pinch grip, and palmar abduction. At the power grip, the force of digit 2-5 was measured separately by a sensor glove. For each measurement, 3 trials were recorded subsequently.Study Design
A within-subject research design was used in this prospective study. Each subject served as the control by preinjection measurements of grip and pinch strength. Subsequent measurements after median nerve block were used to examine within-subject change.Results
In power grip, there was no significant reduction of maximum grip force with median nerve block compared with grip force without block. By measuring the finger forces by a sensor glove, a reduction of force at the individual fingers was found compared with the setting with no block, although significant only at the middle finger (P < .017). With median nerve block, average grip force decreased significantly 20% in pincer grip (P < .021), 29.5% in pinch grip (P < .002), 39.5% in precision grip (P < .001), and 70.7% in palmar abduction (P < .013).Conclusions
These experiments suggest a minor role of the measurement of the power grip force in the diagnostics of distal median nerve block with the dynamometer, which could not be substantially improved by the digit forces and the force distribution of the individual fingers. The assessment of other grip forms, such as pincer grasp, precision grip, pinch grip, and especially palmar abduction, leads to a relevant improvement in the diagnostics of distal median nerve lesion.Level of Evidence
