Three months prior to the tendon repair, he had a two-level cervical spine discectomy and fusion (C4–5, C5–6) that improved his neck pain. Florid suprascapular neuropathy was detected 10 weeks after the open rotator cuff repair. Evidence of some nerve recovery resulted in a long period of observation. But unsatisfactory improvement warranted decompression of the suprascapular notch, which was found to be very stenotic. At surgery, there was no evidence of neuroma, cyst, or other compressing lesion or tissue. Therefore, it was ultimately hypothesized that there was an exacerbation of a preexisting, but clinically unrecognized, entrapment of the suprascapular nerve in the suprascapular notch in the setting of cervical radiculopathy (primarily C5). Retrospectively it was also concluded that had this compressive etiology been recognized, it would have favored prompt decompression rather than the long observation period. Three years was required to achieve a good result following suprascapular notch decompression. The underlying C5 radiculopathy may have created a “double crush syndrome” that contributed to the propensity for injury and the prolonged recovery. There should be heightened awareness of this problem in patients who do not have satisfactory improvement in shoulder pain from previous shoulder and neck surgery.","PeriodicalId":15280,"journal":{"name":"Journal of Brachial Plexus and Peripheral Nerve Injury","volume":"10 1","pages":"e66 - e73"},"PeriodicalIF":0.7,"publicationDate":"2015-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0035-1567807","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58114385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dislocated shoulder girdle was reduced and stabilized with osteosynthesis of the fractured clavicle and reattachment of the trapezius avulsed from the scapular spine for removal of continuous traction force to these damaged nerves. Because of no evidence of recovery on manual muscle test and electromyogram, exploration for these nerves was administered 6 weeks after injury. Although neurolysis of both nerves revealed neural continuity, excessive tension still existed on the suprascapular nerve. It was thought that previous operation in which the shoulder girdle had been reduced and stabilized as much as possible could not achieve complete anatomical reduction of the scapula. As an additional treatment, medial walls of the suprascapular and spinoglenoid notches were shaven to relax the suprascapular nerve. After a year, complete recovery of both the axillary and suprascapular nerve was identified. Although scapulothoracic dissociation is commonly recognized as massive injury of the shoulder girdle with poor prognosis because of existence of accompanied severe neurovascular injuries, there are more than a few cases in which partial damage on the infraclavicular brachial plexus is only accompanied. In case of them, there is the possibility of lesions in continuity of the nerves in which good prognosis might be expected with surgical intervention including early reduction of the shoulder girdle for removal of excessive tension to the damaged nerve.","PeriodicalId":15280,"journal":{"name":"Journal of Brachial Plexus and Peripheral Nerve Injury","volume":"10 1","pages":"e62 - e65"},"PeriodicalIF":0.7,"publicationDate":"2015-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0035-1566740","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58112349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the relation between residual muscle strength and shoulder joint contractures in children with sequelae of obstetric brachial plexus lesion (OBPL). In OBPL a shoulder joint contracture is a frequent finding. We hypothesize that residual internal and external rotator strength and their balance are related to the extent of shoulder joint contracture. Methods Clinical assessment was performed in 34 children (mean 10.0 years) with unilateral OBPL and Narakas classes I–III. External and internal rotation strengths were measured with the shoulder in neutral position using a handheld dynamometer. Strength on the affected side was given as percentage of the normal side. Contracture was assessed by passive internal and external rotations in degrees (in 0° abduction). Mallet classification was used for active shoulder function. Results External and internal rotation strengths on the affected side were approximately 50% of the normal side and on average both equally affected: 56% (SD 18%) respectively 51% (SD 27%); r = 0.600, p = 0.000. Residual strengths were not related to passive internal or external rotation (p > 0.200). Internal rotation strength (r =  − 0.425, p <0.05) was related to Narakas class. Mallet score was related to external and internal rotation strengths (r = 0.451 and r = 0.515, respectively; p < 0.01). Conclusion The intuitive notion that imbalances in residual muscle strength influence contracture formation cannot be confirmed in this study. Our results are of interest for the understanding of contracture formation in OBPL.","PeriodicalId":15280,"journal":{"name":"Journal of Brachial Plexus and Peripheral Nerve Injury","volume":"10 1","pages":"e23 - e29"},"PeriodicalIF":0.7,"publicationDate":"2015-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0035-1558425","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58087432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It characteristically starts with an acute unilateral shoulder pain followed by a complex of symptoms, including weakness, paresthesias, and numbness. The cause of this syndrome is unknown and difficult to diagnose in the initial phase but may occur postsurgery, postinfection, posttrauma, or postvaccination. In this case, the patient's inciting event appeared to be a cesarean section. There was no trauma to the shoulder or upper extremity by way of positioning during the procedure. Several months after denervation of the supraspinatus and infraspinatus muscles, electromyography revealed some improvement. The diagnosis was made through a combination of clinical evaluation, ultrasound, magnetic resonance imaging, and electromyography. With the exception of weakness, this patient experienced few symptoms. Treatment is symptomatic including anti-inflammatories, opiates, and neuroleptics for pain. There is some evidence that immunotherapy may help decrease the length of symptoms, but there is no strong evidence to support steroid use. Physical therapy, the foundation of therapy in this case, is a useful adjunct for rehabilitation. In general, this condition has a good prognosis for recovery, although often slow, even when there is complete denervation. This patient made a full recovery and has no lingering symptoms.","PeriodicalId":15280,"journal":{"name":"Journal of Brachial Plexus and Peripheral Nerve Injury","volume":"10 1","pages":"e50 - e52"},"PeriodicalIF":0.7,"publicationDate":"2015-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0035-1558424","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58087366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, late appearance of paraparesis due to formation of an extradural arachnoid cyst as a sequel of brachial plexus injury is extremely rare and the literature regarding this issue is scarce revealing only 11 cases. Herein, we report a patient with delayed progressive spastic paraparesis appearing after a multilevel brachial plexus root avulsion injury where imaging revealed formation of a large traumatic extradural arachnoid cyst at the cervicothoracic region. Furthermore, to propose that a high-energy trauma might simultaneously result in delayed formation of an extradural arachnoid cyst. However, preganglionic root avulsion injury with pseudomeningocele formation in association with extradural arachnoid cyst is not reported previously. A case of a 36-year-old man with spastic paraparesis developing 2 years after a multilevel brachial plexus root avulsion injury is presented. Root avulsion had immediately resulted in complete paralysis of the left upper limb that had not ameliorated. Imaging studies of the cervicothoracic region disclosed left-sided multilevel pseudomeningoceles and a large extradural arachnoid cyst extending from C5 to T2. After appropriate en bloc laminotomy, the cyst was excised and the causative dural tear was closed. Subsequently, three large defects of pseudomeningoceles were obliterated with artificial dural patch for the prevention of cord herniation. This was followed with laminoplasty of the corresponding levels after dural closure. The postoperative course was uneventful and paraparesis recovered steadily within 2 months. Paraparesis even years after brachial plexus injury should be regarded as a serious event that deserves extensive imaging survey for the possibility of the formation of an extradural arachnoid cyst. Careful review of the literature disclosed that the current case is the 12th case that an extradural arachnoid cyst has developed after brachial plexus injury and the first example that the pathogenic factor that might be implicated in occurrence of this rare association could be clarified with review of the MRI features. Actually, the presence of posttraumatic pseudomeningoceles in association with an arachnoid cyst in the current case is in favor of the belief that only preganglionic root injuries that are in close proximity to the spinal canal had been the cause dural tear with remote formation of extradural arachnoid cyst.","PeriodicalId":15280,"journal":{"name":"Journal of Brachial Plexus and Peripheral Nerve Injury","volume":"10 1","pages":"e43 - e49"},"PeriodicalIF":0.7,"publicationDate":"2015-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/s-0035-1558426","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58087448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spinal disorders and related surgery are a rather new field, interesting neurologists, radiologists, orthopaedic surgeons, and neurosurgeons. Beside huge multiauthored textbooks, there is a place for concise, well-documented textbooks where the interested colleague could find sound basic knowledge, essential information about major pathologies, and their treatment, in a compact textbook with an equilibrium between a well-organized text and enough informative figures. The new “Essentials of Spinal Disorders” issued in early 2014 responds to this challenge and brings up well-written chapters about spine pathology—traumatic, degenerative, inflammatory, or tumoral. The reader is first addressed with anatomy, imaging, and biomechanics of the spine, and then finds essential science about the major pathologies. Both authors are dedicated orthopaedic spine surgeons from the University of Massachusetts (Worcester, Massachusetts, United States) and did a very good job by bringing their knowledge into this book with a good general structure, wellreferenced chapters, and attracting figures. Of course, this book is not an encyclopedia, but it may be easily opened by all interested conservative and operative colleagues—and why not by related health professionals (physiotherapists) as they could rapidly find pertinent information about a particular pathology, an operative technique including well-descriptive figures, or basic knowledge once you get more interested in the spine. Dr. Eck and DiPaola wanted us to become curious about the spine, and they succeeded in having us engrossed into a chapter once we started to skim through it. Any confirmed spine specialist certainly will need to extend his knowledge with further reading, but all those looking for precise and short basic knowledge will be very satisfied.","PeriodicalId":15280,"journal":{"name":"Journal of Brachial Plexus and Peripheral Nerve Injury","volume":"10 1","pages":"e74 - e74"},"PeriodicalIF":0.7,"publicationDate":"2015-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/S-0035-1551653","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58057461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to evaluate the prognostic significance of several neuromuscular parameters in infants with OBPL regarding the later development of elbow flexion contractures. Methods  Twenty infants with OBPL with insufficient signs of recovery in the first months of life who were neurosurgically reconstructed were included. At a mean age of 4.6 months, the following neuromuscular parameters were assessed: existence of flexion contractures, cross-sectional area (CSA) of upper arm muscles on MRI, Narakas classification, EMG results, and elbow muscle function using the Gilbert score. In childhood at follow-up at mean age of 7.7 years, we measured the amount of flexion contractures and the upper arm peak force (Newton). Statistical analysis is used to assess relations between these parameters. Results  Flexion contractures of greater than 10 degrees occurred in 55% of our patient group. The relation between the parameters in infancy and the flexion contractures in childhood is almost nonexistent. Only the Narakas classification was related to the development of flexion contractures in childhood ( p  = 0.006). Infant muscle CSA is related to childhood peak muscle force. Conclusion  The role of infancy upper arm muscle hypotrophy/hypertrophy, reinnervation, and early elbow muscle function in the development of childhood elbow contractures remains unclear. In this cohort prediction of childhood flexion, contractures were not possible using infancy neuromuscular parameters. We suggest that contractures might be an adaptive process to optimize residual muscle function.","PeriodicalId":15280,"journal":{"name":"Journal of Brachial Plexus and Peripheral Nerve Injury","volume":"10 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2015-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1055/S-0035-1549368","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"58048985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
