Abstract
BACKGROUND Chiari malformation type 1 (CM1) is a congenital hindbrain malformation characterized by herniation of the cerebellar tonsils below the foramen magnum. The term Chiari type 1.5 is used when herniation of the brainstem under the McRae line and anomalies of the craniovertebral junction are also present. These conditions are associated with several symptoms and signs, including headache, neck pain, and spinal cord syndrome. For symptomatic patients, surgical decompression is recommended. When radiographic indicators of craniovertebral junction (CVJ) instability or symptoms related to ventral brainstem compression are present, CVJ fixation should also be considered. CASE DESCRIPTION We report the case of a 13-year-old girl who presented with severe tetraparesis after posterior decompression for Chiari malformation type 1.5, followed 5 days later by partial C2 laminectomy. Several months after the initial surgery, she underwent two fixations, first without and then with intraoperative cervical traction, leading to significant neurological improvement. DISCUSSION AND CONCLUSION This case report underscores the importance of meticulous radiological analysis before CM surgery. For CM 1.5 patients with basilar invagination, CVJ fixation is recommended, and C2 laminectomy should be avoided. In the event of significant clinical deterioration due to nonadherence to these guidelines, our findings highlight the importance of traction with increased extension before fixation, even years after initial destabilizing surgery.

Abstract
Improving upper extremity function in high cervical spinal cord injury (SCI) patients with tetraplegia is a challenging task owing to the limited expendable donor muscles and nerves that are available. Restoring active wrist extension for these patients is critical because it allows for tenodesis grasp. This is classically achieved with brachioradialis (BR) to extensor carpi radialis brevis (ECRB) tendon transfer, but outcomes are suboptimal because BR excursion is insufficient and its origin proximal to the elbow further limits the functionality of the tendon transfer, particularly in the absence of elbow extension. As an alternative approach to restore wrist extension in patients with ICSHT group 1 SCI, we present the first clinical report of the BR to extensor carpi radialis longus (ECRL) and BR to ECRB nerve transfers.

Abstract
Traumatic spinal cord injury (SCI) is a major cause of severe and permanent disability in young adults. Overweight and obesity are commonly observed among patients affected with SCI, with reports of a prevalence of over 60 and 30% respectively. Case report: A 34 year-old woman suffering from tetraplegia after sustaining a traumatic injury to C5-C6 at age 23 as a result of a motor vehicle accident was presented to our hospital's multidisciplinary bariatric team due to class II obesity. At the time of presentation to the team, eleven years after the accident, her BMI was calculated to be 39 Kg/m2 (weight 97 kg, height 1.57 meters). She was diagnosed with infertility while seeking pregnancy, and referred to our bariatric unit for weight loss. In addition, she had overcome the physical limitations of her injury, had a regular job and was engaged in regular physical activities such as swimming. In May 2017, she underwent laparoscopic sleeve gastrectomy (LSG) without complications and was discharged on postoperative day 2. 17 months following LSG, with a normal BMI, she became naturally pregnant. She had emergency cesarean at 35 weeks due to pneumonia but both patient and child recovered without sequelae. Currently, 4 years after surgery she maintains 37.11% total weight loss (weight 61 kg). She reports having a better quality of life with fewer medical intercurrencies. Conclusions: Patients with SCI and obesity, particularly women seeking to conceive, may be benefited by being referred to bariatric teams for assessment and treatment to improve results associated with sustained weight reduction.

Abstract
The reconstruction of arm and hand functions is of enormous importance for tetraplegic patients as it enables at least some degree of independence. Depending on the level of the spinal cord injury, certain residual functions are present in the arms which can be used for surgical reconstruction of upper extremity functions. By utilizing tendon and nerve transfers missing functions can at least be partially reconstructed. Tendon transfers are a proven technique with reliable results that can be performed at any time regardless of the type of accident. Due to the frequent presence of lower motor neuron damage, it is essential to consider the optimal time window for nerve transfer interventions. From the multitude of surgical options, an individual reconstruction plan must be created for each patient, which considers multiple factors. The combination of nerve transfers and later completing the functional reconstruction by tendon transfers is the preferred concept of the authors of this article.

Abstract
BACKGROUND There are approximately 140 000 people in Germany with spinal cord injury, with approximately 2400 new patients each year. Cervical spinal cord injuries cause, to varying degrees, weakness and impairment of everyday activities of the limbs (tetraparesis, tetraplegia). METHODS This review is based on relevant publications retrieved by a selective search of the literature. RESULTS From among 330 initially screened publications, 40 were included and analyzed. Muscle and tendon transfers, tenodeses, and joint stabilizations yielded reliable functional improvement of the upper limb. Tendon transfers improved the strength of elbow extension from M0 to an average of M3.3 (BMRC) and grip strength to approximately 2 kg. In the long term, 17-20% of strength is lost after active tendon transfers and slightly more after passive ones. Nerve transfers improved strength to M3 or M4 in over 80% of cases, with the best results overall in patients under 25 years of age who underwent early surgery (within 6 months of the accident). Combined procedures in a single operation have been found to be advantageous compared to the traditional multistep approach. Nerve transfers from intact fascicles at segmental levels above that of the spinal cord lesion have been found to be a valuable addition to the established varieties of muscle and tendon transfer. The reported long-term patient satisfaction is generally high. CONCLUSION Modern techniques of hand surgery can help suitably selected tetraparetic and tetraplegic patients regain the use of their upper limbs. Competent interdisciplinary counseling about these surgical options should be offered as early as possible to all affected persons as an integral part of their treatment plan.

Abstract
AIM We report the comparative results of functional upper extremity surgery plans in patients with tetraplegia, including restoration of elbow extension and construction of a key grip in a "one-stage" or "two-stage" operation. MATERIALS AND METHODS A series of 36 patients with tetraplegia, with a total of 45 operated upper limbs, was analyzed retrospectively with a mean follow-up of 23 months (13-39 months). We evaluated the analytical strength of elbow extension using the MRC (Medical Research Council) score, the strength of the key grip (kg/F) as well as the autonomy of the patients using functional scores; Lamb (/100) and QIF (Quadriplegia Index of Function) (/100). RESULTS Sixteen upper limbs were included in the "one-stage" group and 29 in the "two-stage" group. The groups were comparable preoperatively. Elbow extension strength was 3.6/5 in the one-stage group versus 3.7/5, p=0.74. Grip strength was 1.8kg/F in the one-stage group versus 1.3kg/F, p=0.22. Regarding the functional scores, there was no statistically significant difference between the two groups for the Lamb score (p=0.46) and the QIF (p=0.42). There was no statistically significant difference in terms of the frequency of complications for the elbow (p=0.49) and for the hand (p=0.17). The total duration of the one-stage surgery plan averaged 7.5 months compared to 24.7 months for the two-stage plan, p<0.01. The mean follow-up for the one-stage group was 21 months versus 24 months for the two-stage group. CONCLUSION The results of both plans are similar and indicate that the "one-stage" plan is a reliable option. This all-in-one surgical option reduces postoperative follow-up and dropout rates for patients during the plan timeframe. LEVEL OF EVIDENCE IV; retrospective clinical series.

Abstract
The Grasp and Release Test (GRT) was originally developed to measure effectiveness of an implanted neuroprosthesis in people with tetraplegia. Its ease of use and lack of floor and ceiling effects culminated in recommendations for inclusion in a battery of tests to measure outcome following upper limb reconstructive surgery. However, the length of time taken to administer the GRT in a clinical setting, lack of instructions of accepted grasp patterns in the upper limb reconstructive surgery population and scoring procedures lead to differences in reporting outcomes using this measure. In order to ensure clinical utility for the upper limb reconstructive surgery population, revisions of the original test instructions have been made and are reported in this article. Further testing of the psychometric properties of the new measure are currently underway.

Abstract
We report a retrospective study of 112 nerve transfers in 39 participants to investigate predictors of strength outcomes after nerve transfer surgery for upper limb reanimation in tetraplegia. We measured clinical and pre- and intraoperative neurophysiological assessment variables and compared them with strength outcomes 2 years after nerve transfer surgery. We found statistically significant improvement in Medical Research Council strength grades after nerve transfer surgery with lower cervical spine injuries (between one and two grades), lower donor nerve stimulation thresholds (half of a grade), greater motor evoked potential activity in recipient nerves (half of a grade) and greater muscle responses to intraoperative stimulation of donor (half of a grade) and recipient nerves (half of a grade).Level of evidence: III.

Abstract
Patients with mucopolysaccharidosis type IVA (MPS IVA) have many risk factors for myelopathy and paresis. These are spinal cord compression, bone stenosis, and soft tissue thickening with ligament laxity, deformity, odontoid hypoplasia, and atlantoaxial instability. Although most patients with MPS IVA appear generally healthy at birth, patients often show skeletal deformities within a few years. Surgical indications are difficult to determine. Historically, many physicians have used prophylactic decompression and fusion in young, asymptomatic MPS IVA patients to prevent cord compression. Although spinal cord decompression is usually required at the craniocervical junction in patients with MPS IVA, decompression may be required at other spinal cord levels as well. There is a risk of developing neurological damage during surgery. The most common causes are ischemia secondary to cardiac output deteriorated in the prone position or due to artery damage, and local trauma due to neck movements or traction while bringing the patient to the prone position. Neurophysiological monitoring is very important during surgery to reduce the risk of neurological damage in spinal cord surgery. In this case report, a case with loss of lower extremity neuromonitorization motor evoked potential (MEP) responses in the early period of surgery without any intervention to the craniocervical junction after prone positioning will be presented.

Abstract
IMPORTANCE Cervical spinal cord injury (SCI) causes devastating loss of upper extremity function and independence. Nerve transfers are a promising approach to reanimate upper limbs; however, there remains a paucity of high-quality evidence supporting a clinical benefit for patients with tetraplegia. OBJECTIVE To evaluate the clinical utility of nerve transfers for reanimation of upper limb function in tetraplegia. DESIGN, SETTING, AND PARTICIPANTS In this prospective case series, adults with cervical SCI and upper extremity paralysis whose recovery plateaued were enrolled between September 1, 2015, and January 31, 2019. Data analysis was performed from August 2021 to February 2022. INTERVENTIONS Nerve transfers to reanimate upper extremity motor function with target reinnervation of elbow extension and hand grasp, pinch, and/or release. MAIN OUTCOMES AND MEASURES The primary outcome was motor strength measured by Medical Research Council (MRC) grades 0 to 5. Secondary outcomes included Sollerman Hand Function Test (SHFT); Michigan Hand Outcome Questionnaire (MHQ); Disabilities of Arm, Shoulder, and Hand (DASH); and 36-Item Short Form Health Survey (SF-36) physical component summary (PCS) and mental component summary (MCS) scores. Outcomes were assessed up to 48 months postoperatively. RESULTS Twenty-two patients with tetraplegia (median age, 36 years [range, 18-76 years]; 21 male [95%]) underwent 60 nerve transfers on 35 upper limbs at a median time of 21 months (range, 6-142 months) after SCI. At final follow-up, upper limb motor strength improved significantly: median MRC grades were 3 (IQR, 2.5-4; P = .01) for triceps, with 70% of upper limbs gaining an MRC grade of 3 or higher for elbow extension; 4 (IQR, 2-4; P < .001) for finger extensors, with 79% of hands gaining an MRC grade of 3 or higher for finger extension; and 2 (IQR, 1-3; P < .001) for finger flexors, with 52% of hands gaining an MRC grade of 3 or higher for finger flexion. The secondary outcomes of SHFT, MHQ, DASH, and SF36-PCS scores improved beyond the established minimal clinically important difference. Both early (<12 months) and delayed (≥12 months) nerve transfers after SCI achieved comparable motor outcomes. Continual improvement in motor strength was observed in the finger flexors and extensors across the entire duration of follow-up. CONCLUSIONS AND RELEVANCE In this prospective case series, nerve transfer surgery was associated with improvement of upper limb motor strength and functional independence in patients with tetraplegia. Nerve transfer is a promising intervention feasible in both subacute and chronic SCI.

Abstract
Regaining upper extremity function is a prioritized matter for patients with tetraplegia after a cervical spinal cord injury (cSCI). The purpose of this article is to describe the current evidence and treatment strategies for upper extremity reconstruction after cSCI at the Centre for Advanced Reconstruction of Extremities, Sahlgrenska University Hospital, Sweden. The specialized unit works in a multidisciplinary setting to optimize the care of the patient population. Preoperative planning and an individualized treatment according to the needs and abilities of the patient are considered key points to achieve the best possible outcome. The addition of nerve transfers to the established method of tendon transfers for grip reconstruction has led to increased possibilities to achieve both functional hand opening and grip. Here we present our preferred method of upper extremity reconstruction, which involves a two-staged procedure where the tendon-based grip reconstruction is preceded by nerve transfer of the supinator to posterior intraosseous nerve whenever possible. Important clinical aspects as well as future perspectives are discussed.

Abstract
INTRODUCTION Although pneumocephalus is very common after intracranial or spinal surgeries, pneumoventricle is uncommon. Tension pneumoventricle (tPV) occurs when air in the ventricles expands to cause neurological deficits or mass effect. It is usually seen with a combination of a ball-valve defect postoperatively that sucks in air and a ventriculoperitoneal shunt that drains cerebrospinal fluid and allows the ingress of air. CASE REPORT A young man developed delayed tPV after surgery for craniopharyngioma. He required multiple surgeries and occlusion of the ventriculoperitoneal shunt before the tPV resolved. CONCLUSIONS The probable mechanisms of tPV and the importance of early recognition and treatment are discussed. A review of the literature of this uncommon entity has also been performed.

Abstract
PURPOSE The rates of upper extremity reconstruction for patients with tetraplegia remain low. We performed a retrospective study to assess recent reconstruction rates and delineate factors associated with the occurrence of reconstruction. METHODS We examined the National Inpatient Sample database (2012-2017) for the rate of reconstruction for patients with tetraplegia. The details of provider distribution characteristics and neighborhood attributes were obtained from the American Medical Association Physician Masterfile and based on the area deprivation index, respectively. We calculated the mean reconstruction rate per year and generated multivariable logistic regression models to examine the influence of patient factors, hospital characteristics, and provider distribution on the odds of undergoing functional reconstruction for tetraplegia patients. RESULTS Among 404,660 encounters with patients with tetraplegia, only 1,430 (0.4%) patients underwent upper extremity reconstruction from 2012 to 2017, with a mean rate of 238 procedures per year. We identified 5,450 hand surgeons, 12,751 physiatrists, and 444 spinal cord injury specialists, with variation in their national distribution. A greater number of surgeons near SCIS was associated with increased probability of reconstruction (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.03-1.12). The odds of surgery were greater for patients receiving care at urban teaching (OR 5.00, 95% CI 3.35-7.47) or urban nonteaching (OR 1.71, 95% CI 1.11-2.63) hospitals, whereas those at private nonprofit (OR 0.67, 95% CI 0.58-0.78) or investor-owned (OR 0.65, 95% CI 0.52-0.82) hospitals had lower odds. Although most patients had insurance coverage, patients with a higher income or those who received subsidized care had greater odds of undergoing reconstruction. CONCLUSIONS Reconstruction rates remain low and are correlated with the environment of care, financial factors, and provider availability. Policies that focus on reducing these factors in addition to increasing interspecialty collaboration could improve access to surgery for patients with tetraplegia. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic I.

Abstract
Reconstruction of arm and hand function in patients with a cervical spinal cord injury can improve their quality of life. Elbow extension, wrist extension, grip function and opening of the hand can be reconstructed. Traditionally, this has been done through tendon transpositions. Nerve transfer is a new technique. A functioning motor nerve branch is moved and connected to a muscle or muscle group damaged by the spinal cord injury. This technique has several advantages. Multiple functions can be restored by one nerve transfer, no long-term hand-rehabilitation is required and there is no risk of adhesions of the transposition. The most important disadvantage is the recovery time, as a results of the slow ingrowth of the nerve transfer, which takes at least 12 to 18 months. For each spinal cord injury patient, an individual action plan must be made, because not every patient has the same options and these are sometimes very limited.

Abstract
INTRODUCTION Calcification of ligamentum flavum (CLF) is an important cause of spinal stenosis and spinal cord compression. CLF does not usually induce immediate quadriparesis. Here we describe a rare case of immediate quadriparesis due to a large calcified mass containing liquids in the ligamentum flavum, which was easily confused with gout crystals. PATIENT CONCERNS A 74-year-old Asian male felt progressive bilateral arm and leg weakness. On the fourth day, acute quadriparesis occurred. DIAGNOSIS Coronal and sagittal computerized tomography (CT) and magnetic resonance imaging (MRI) showed a large circular mass in the left posterior part of the cervical 3/4 spinal canal, protruding into the canal, and occupying one-half of the spinal canal. INTERVENTIONS Emergency laminectomy was performed at C3/4 level. The huge cyst was excised and 1 ml of white viscous liquid flowed out. OUTCOMES After operation, CT and MRI showed a full laminectomy of C3/4 and complete decompression of the cervical spinal cord. Hematoxylin-eosin (HE) staining showed that large amounts of calcium was deposited around cystic tissues. Five-year follow-up after laminectomy showed good recovery. CONCLUSION This case of immediate quadriparesis, caused by a large calcified mass containing fluid, is very rare. It should be at the earliest stage of calcification. Laminectomy is an effective treatment. This calcification was deceptive and was easily confused with gout crystals. It can help to understand the exact pathophysiology of CLF.

Abstract
BACKGROUND Loss of upper extremity function after cervical spinal cord injury greatly affects independence, including social, vocational, and community engagement. Nerve transfer surgery offers an exciting new option for the reanimation of upper limb function in tetraplegia. The aim of this study was to evaluate the outcomes of nerve transfer surgery used for the reanimation of upper limb function in tetraplegia. METHODS In this prospective case series, we consecutively recruited people of any age with early (<18 months post-injury) cervical spinal cord injury of motor level C5 and below, who had been referred to a single centre for upper extremity reanimation and were deemed suitable for nerve transfer. All participants underwent single or multiple nerve transfers in one or both upper limbs, sometimes combined with tendon transfers, for restoration of elbow extension, grasp, pinch, and hand opening. Participants were assessed at 12 months and 24 months post-surgery. Primary outcome measures were the action research arm test (ARAT), grasp release test (GRT), and spinal cord independence measure (SCIM). FINDINGS Between April 14, 2014, and Nov 22, 2018, we recruited 16 participants (27 limbs) with traumatic spinal cord injury, among whom 59 nerve transfers were done. In ten participants (12 limbs), nerve transfers were combined with tendon transfers. 24-month follow-up data were unavailable for three patients (five limbs). At 24 months, significant improvements from baseline in median ARAT total score (34·0 [IQR 24·0-38·3] at 24 months vs 16·5 [12·0-22·0] at baseline, p<0·0001) and GRT total score (125·2 [65·1-154·4] vs 35·0 [21·0-52·3], p<0·0001) were observed. Mean total SCIM score and mobility in the room and toilet SCIM score improved by more than the minimal detectable change and the minimal clinically important difference, and the mean self-care SCIM score improved by more than the minimal detectable change between baseline and 24 months. Median Medical Research Council strength grades were 3 (IQR 2-3) for triceps and 4 (IQR 4-4) for digital extensor muscles after 24 months. Mean grasp strength at 24 months was 3·2 kg (SD 1·5) in participants who underwent distal nerve transfers (n=5), 2·8 kg (3·2) in those who had proximal nerve transfers (n=9), and 3·9 kg (2·4) in those who had tendon transfers (n=8). There were six adverse events related to the surgery, none of which had any ongoing functional consequences. INTERPRETATION Early nerve transfer surgery is a safe and effective addition to surgical techniques for upper limb reanimation in tetraplegia. Nerve transfers can lead to significant functional improvement and can be successfully combined with tendon transfers to maximise functional benefits.

Abstract
BACKGROUND Tendon transfer surgery can effectively improve hand function for patients with tetraplegia but remains poorly utilized. Little is known regarding how patients' rehabilitation experiences influence their perception of function, identity, and coping to shape their reconstructive context. METHODS We performed a cross-sectional qualitative analysis of 19 participants with C4-C7 cervical spinal injuries: 9 patients had undergone reconstruction; 10 had not. Semistructured interviews were conducted using an interview guide focusing on rehabilitation experience, the relationship between function and identity, and how patient experience evolved. Interview transcripts were analyzed using grounded theory. RESULTS The study sample was predominantly male (79%), white (89%), and American Spinal Injury Association grades A-D (grade A: 42%; grade B: 32%; grade C: 16%; grade D: 10%). Recognizing rehabilitation's necessity, functional gains, and constructive patient-therapist relationships promoted engagement in therapy. Poor insurance coverage and financial constraints decreased rehabilitation access. Function affected identity through the degree to which it tied participants to a "patient" role. Early in recovery, patients' function, roles, and attitudes were fluid but solidified over time; how satisfied patients were with these final positions influenced how they coped. CONCLUSION The balance of patients' positive and negative coping has been found to influence patients' progression to surgery. This study describes how function and identity contribute to coping. Participants' function and identity evolved during a finite period we call "the golden year," before reaching a fixed point around which they built their lives. The norms patients establish during this time may affect receptiveness to surgery.

Abstract
PURPOSE To explore the feasibility of restoring all finger flexion after a cervical spinal cord injury. METHODS Double nerve transfer was conducted in 22 cadaver upper extremities. Donor nerves were the brachialis branch of the musculocutaneous nerve and the extensor carpi radialis brevis (ECRB) branches of the radial nerve. Recipient nerves were the anterior interosseous nerve (AIN) and the flexor digitorum profundus (FDP) branch of ulnar nerve (ulnar-FDP). Nerve transfers were evaluated on 3 parameters: surgical feasibility, donor-to-recipient axon count ratio, and distance from the coaptation site to the muscle entry of recipient nerve. A complete C6 spinal cord injury reconstruction was accomplished in a patient using a double nerve transfer of ECRB to ulnar-FDP and brachialis to AIN. RESULTS In the cadaver study, nerve transfers from ECRB to AIN, brachialis to AIN, and ECRB to ulnar-FDP were all feasible. The transfer from the brachialis to ulnar-FDP was not possible. Mean myelinated axon counts of AIN, brachialis, ulnar-FDP, and ECRB were 2,903 ± 1049, 1,497 ± 606, 753 ± 364, and 567 ± 175, respectively. The donor-to-recipient axon count ratios of ECRB to AIN, brachialis to AIN, and ECRB to ulnar-FDP were 0.24 ± 0.15, 0.55 ± 0.38, and 0.98 ± 0.60, respectively. The distance from coaptation of the ECRB to the ulnar-FDP muscle entry was shorter than for the other nerve transfers (54 ± 14.29 mm). At 18 months, there was restoration of flexion in all fingers and functional improvement from double nerve transfer of the brachialis to the AIN and the ECRB to the ulnar-FDP. CONCLUSIONS Restoration of all finger flexion may be feasible by the ECRB to ulnar-FDP and brachialis to AIN double nerve transfer. CLINICAL RELEVANCE Double nerve transfer can be used in C6-C7 spinal cord injury and patients with lower arm-type brachial plexus injury who have no finger flexion but have good brachialis and ECRB.

Abstract
RATIONALE We report on a stroke patient who showed restoration of discontinued corticoreticular pathways (CRPs) on serial diffusion tensor tractography (DTT) concurrent with recovery of gait disturbance following shunt operation for hydrocephalus. PATIENT CONCERNS A 67-year-old female patient underwent stereotactic drainage for management of intraventricular hemorrhage due to a rupture of the left posterior communicating artery. DIAGNOSES After 4 weeks from onset, the patient exhibited quadriparesis with more severe weakness in the proximal muscles and could not even stand or walk. She underwent comprehensive rehabilitation for 3 weeks. Her quadriparesis, as a result of hydrocephalus, did not improve significantly. INTERVENTIONS On the pre-op DTT, discontinuations (the right CRP: at subcortical white matter level, and the left CRP: at the midbrain level) of the CRP fibers from the premotor cortex were observed in both hemispheres. OUTCOMES She underwent a ventriculo-peritoneal shunt operation and her quadriparesis improved, especially the proximal muscles. Consequently, she could walk with mild assistance on an even floor at 5 days and walk on stairs at 4 weeks after the shunt operation. On the post-op DTT, the discontinued CRP fibers were elongated to the premotor cortex in both hemispheres. LESSONS Restoration of discontinued CRPs concurrent with recovery of gait disturbance following shunt operation for hydrocephalus was demonstrated in a stroke patient.

Abstract
Spinal cord injury without any radiographic abnormality (SCIWORA) is rare in adults. We describe here two case reports of adult patients, who presented to us with quadriplegia, following a road traffic accident. Plain radiography and computed tomography (CT) of cervical spine were normal. Hence the patients were diagnosed as cases of adult SCIWORA. However, subsequent magnetic resonance imaging (MRI) of the two patients revealed cervical cord injury in the form of cord contusion and disc protrusion, respectively. Patient with cord contusion was managed medically, whereas the patient with disc lesion was treated with discectomy. Patient treated with discectomy showed marked improvement. Therefore, patients having no osseous injury on X ray and CT scan should have an MRI study done to look for surgically correctable pathology. As in such rare patients of SCIOWRA an early diagnosis and timely intervention is crucial; with MRI playing a pivotal role.

Checkpoints to Progression: Qualitative Analysis of the Personal and Contextual Factors That Influence Selection of Upper Extremity Reconstruction Among Patients With Tetraplegia. J Hand Surg Am 2017; 42:495-505.e11. [PMID: 28669418 PMCID: PMC5753404 DOI: 10.1016/j.jhsa.2017.04.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2016] [Revised: 04/07/2017] [Accepted: 04/10/2017] [Indexed: 02/02/2023]
Abstract
PURPOSE Patients with tetraplegia consistently rank better use of the upper extremity as their top functional priority. Multiple case series have demonstrated that upper extremity reconstruction (UER) is well-tolerated and can produce substantial functional improvements for appropriate candidates; however, UER remains critically underutilized. The mechanisms that drive differences in provider practice and referral patterns have been studied, but comprehensive examination of the patient factors that influence UER decisions has not been performed for American patients. METHODS Nineteen patients with C4-8 cervical spinal injuries were selected using purposive sampling: 9 patients had undergone UER, 10 had not undergone UER. Semistructured interviews were conducted and transcripts evaluated using grounded theory methodology. RESULTS Our study yielded a conceptual model that describes the characteristics common to all patients who undergo UER. Patients who selected reconstruction proceeded stepwise through a shared sequence of steps: (1) functional dissatisfaction, (2) awareness of UER, and (3) acceptance of surgery. Patients' ability to meet these criteria was determined by 3 checkpoints: how well they coped, their access to information, and the acceptability of surgery. Extremely positive or negative coping prevented patients from moving from the Coping to the Information Checkpoint; thus, they remained unaware of UER and did not undergo surgery. A lack of knowledge regarding reconstruction was the strongest barrier to surgery among our participants. CONCLUSIONS We built a conceptual model that outlines how patients' personal and contextual factors drive their progression to UER. Moving from functional dissatisfaction to understanding that they were candidates for UER was a substantial barrier for participants, particularly those with very high and very low coping skills. CLINICAL RELEVANCE To improve utilization for all patients, interventions are needed to increase UER awareness. Standardizing introduction to UER during the rehabilitation process or improving e-content may represent key awareness access points.

Abstract
OBJECTIVES To quantify time from spinal cord injury to upper limb reconstructive surgery for individuals with tetraplegia; to explore influences on decision-making about surgery for persons with long-standing (>10y) tetraplegia; and to determine the applicability of our previously developed conceptual framework that described the decision-making processes for people with tetraplegia of <5 years. DESIGN Quantitative-qualitative mixed-methods study. SETTING Community based in New Zealand. PARTICIPANTS People (N=9) living with tetraplegia for >10 years. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES An audit of time frames between injury, assessment, and surgery for people with tetraplegia was undertaken. Interviews of people with tetraplegia were analyzed using constructivist grounded theory. RESULTS Sixty-two percent of people with tetraplegia assessed for surgery had upper limb reconstructive surgery. Most were assessed within the first 3 years of spinal cord injury. Over half had surgery within 4 years after injury; however, 20% waited >10 years. Changes in prioritized activities, and the identification of tasks possible with surgery, were influential in the decision-making process. Participants were aware of surgery, but required a reoffer from health professionals before proceeding. The influence of peers was prominent in reinforcing the improvement in prioritized activities possible after surgery. CONCLUSIONS Findings confirmed that the previously developed conceptual framework for decision-making about upper limb reconstructive surgery was applicable for people with tetraplegia of >10 years. Similarities were seen in the influence of goals and priorities (although the nature of these might change) and information from peers (although this influence was greater for those injured longer). Repeat offers for surgery were required to allow for changes in circumstances over time.
