- BACKGROUND: Access to pre-hospital trauma care can help minimize many of traffic related mortality and morbidity in low- and middle-income countries with high rate of traffic deaths such as Iran. The aim of this study was to assess if the distribution of pre-hospital trauma care facilities reflect the burden of road traffic injury and mortality in different provinces in Iran. METHODS: This national cross-sectional study is based on ecological data on road traffic mortality (RTM), road traffic injuries (RTIs) and pre-hospital trauma facilities for all 30 provinces in Iran in 2006. Lorenz curves and Gini coefficients were used to describe the distributions of RTM/RTIs and pre-hospital trauma care facilities across provinces. Spearman rank-order correlation was performed to assess the relationship between RTM/RTI and pre-hospital trauma care facilities. RESULTS: RTM and RTIs as well as pre-hospital trauma care facilities were distributed unequally between different provinces. There was no significant association between the rate of RTM and RTIs and the number of pre-hospital trauma care facilities across the country. CONCLUSIONS: The distribution of pre-hospital trauma care facilities does not reflect the needs in terms of RTM and RTIs for different provinces. These results suggest that traffic related mortality and morbidity could be reduced if the needs in terms of RTM and RTIs were taken into consideration when distributing pre-hospital trauma care facilities between the provinces.

- IMPORTANCE Moderate-grade adolescent idiopathic scoliosis (AIS) may be treated with full-timebracing. For patients who reject full-time bracing, the effects of alternative, conservativeinterventions are unknown.OBJECTIVE To determine whether self-mediated physical activity combined with either nighttimebracing (NB) or scoliosis-specific exercise (SSE) is superior to a control of physical activity alone (PA)in preventing Cobb angle progression in moderate-grade AIS.DESIGN, SETTING, AND PARTICIPANTS The Conservative Treatment for Adolescent IdiopathicScoliosis (CONTRAIS) randomized clinical trial was conducted from January 10, 2013, throughOctober 23, 2018, in 6 public hospitals across Sweden. Male and female children and adolescentsaged 9 to 17 years with an AIS primary curve Cobb angle of 25° to 40°, apex T7 or caudal, and skeletalimmaturity based on estimated remaining growth of at least 1 year were included in the study. Datesof analysis were from October 25, 2021, to January 28, 2023.INTERVENTIONS Interventions included self-mediated physical activity in combination with eitherNB or SSE or PA (control). Patients with treatment failure were given the option to transition to afull-time brace until skeletal maturity.MAIN OUTCOMES AND MEASURES The primary outcome was curve progression of 6° or less(treatment success) or curve progression of more than 6° (treatment failure) seen on 2 consecutiveposteroanterior standing radiographs compared with the inclusion radiograph before skeletalmaturity. A secondary outcome of curve progression was the number of patients undergoing surgeryup until 2 years after the primary outcome.RESULTS The CONTRAIS study included 135 patients (45 in each of the 3 groups) with a mean (SD)age of 12.7 (1.4) years; 111 (82%) were female. Treatment success was seen in 34 of 45 patients (76%)in the NB group and in 24 of 45 patients (53%) in the PA group (odds ratio [OR], 2.7; 95% CI, 1.1-6.6).The number needed to treat to prevent curve progression with NB was 4.5 (95% CI, 2.4-33.5).Treatment success occurred in 26 of 45 patients (58%) in the SSE group (OR for SE vs PA, 1.2; 95% CI,0.5-2.8). Up to 2 years after the primary outcome time point, 9 patients in each of the 3 groupsunderwent surgery.CONCLUSIONS AND RELEVANCE In this randomized clinical trial, treatment with NB preventedcurve progression of more than 6° to a significantly higher extent than did PA, while SSE did not; inaddition, allowing transition to full-time bracing after treatment failure resulted in similar surgicalfrequencies independent of initial treatment. These results suggest that NB may be an effectivealternative intervention in patients rejecting full-time bracing.

- Purpose: To compare the patient-derived modified Japanese Orthopaedic Association (P-mJOA) scale with the European myelopathy score (EMS) for the assessment of patients with degenerative cervical myelopathy (DCM). Methods: In this register-based cohort study with prospectively collected data, included patients were surgically treated for DCM and had reported both P-mJOA and EMS scores at baseline, 1-year follow-up, and/or 2-year follow-up to the Swedish Spine Register. P-mJOA and EMS scores were defined as severe (P-mJOA 0–11 and EMS 5–8), moderate (P-mJOA 12–14 and EMS 9–12), or mild (P-mJOA 15–18 and EMS 13–18). P-mJOA and EMS mean scores were compared, and agreement was evaluated with Spearman’s rank correlation coefficient (ρ), the intraclass correlation coefficient (ICC), and kappa (κ) statistics. Results: Included patients (n = 714, mean age 63.2years, 42.2% female) completed 937 pairs of the P-mJOA and the EMS. The mean P-mJOA and EMS scores were 13.9 ± 3.0 and 14.5 ± 2.7, respectively (mean difference –0.61 [95% CI –0.72 to –0.51; p < 0.001]). Spearman’s ρ was 0.84 (p < 0.001), and intra-rater agreement measured with ICC was 0.83 (p < 0.001). Agreement of severity level measured with unweighted and weighted κ was fair (κ = 0.22 [p < 0.001]; κ = 0.34 [p < 0.001], respectively). Severity levels were significantly higher using the P-mJOA (p < 0.001). Conclusion: The P-mJOA and the EMS had similar mean scores, and intra-rater agreement was high, whereas severity levels only demonstrated fair agreement. The EMS has a lower sensitivity for detecting severe myelopathy but shows an increasing agreement with the P-mJOA for milder disease severity. A larger interval to define severe myelopathy with the EMS is recommended.

- Vitamin D supplements have been used to prevent fractures. The effect may be mediated through increased bone mass, but also through reduced falling propensity. The aim of this study was to evaluate the association between 25-hydroxy vitamin D levels (25OHD), fall-associated variables (including tests of functional performance), and fracture in ambulatory women. At baseline 25OHD was measured in 986 women. Fall-associated variables were investigated at baseline. Fractures were recorded during a 3-year follow-up. Four percent of the women had 25OHD levels below 20 ng/ml (50 nmol/l), and 26% had 25OHD levels below 30 ng/ml (75 nmol/l). 25OHD correlated with gait speed (r =0.17, P <0.001), the Romberg balance test (r =0.14, P <0.001), self-estimated activity level (r =0.15, P <0.001), and thigh muscle strength (r =0.08, P =0.02). During the 3-year follow-up, 119 out of the 986 women sustained at least one fracture. The Cox proportional hazard ratio (HR) (95% confidence interval) for sustaining a fracture during the follow-up was 2.04 (1.04-4.04) for the group of women with 25OHD below 20 ng/ml, in which 9 out of 43 women sustained a fracture. Thirty-two of the 256 women with 25OHD levels below 30 ng/ml sustained a fracture during the follow-up, with a non-significant HR of 1.07 (1.07-1.61). This cohort of elderly, ambulatory women had a high mean 25OHD. A low 25OHD was associated with inferior physical activity level, gait speed and balance. A 25OHD level below 30 ng/ml was not associated with an increased risk of fractures in this study. However, a subgroup of women with 25OHD levels below 20 ng/ml had a tendency to an increased risk of fractures, which may be associated with an inferior physical activity and postural stability.

- Objective: To study the effect of whole-body vibration therapy on bone mass, bone turnover and body composition in severely disabled children. Methods: Nineteen non-ambulatory children aged 5.1-16.3 years (6 males, 13 females) with severe motor disabilities participated in an intervention programme with standing exercise on a self-controlled dynamic platform, which included whole-body vibration therapy (vibration, jump and rotation movements). Whole-body vibration therapy was performed at 40-42 Hz, with an oscillation amplitude of 0.2 mm, 5-15 min/treatment, twice/week for 6 months. Bone mass parameters and bone markers were measured at the study start, and after 6 and 12 months. Results: Whole-body vibration therapy was appreciated by the children. Total-body bone mineral density increased during the study period (p less than0.05). Z-scores for total-body bone mineral density ranged from -5.10 to -0.60 at study start and remained unchanged throughout. Approximately 50% of the subjects had increased levels of carboxy-terminal telopeptides of type I collagen and decreased levels of osteocalcin at the start. Body mass index did not change during the intervention period, but had increased by the 12-month follow-up (pless than 0.05). Conclusion: Whole-body vibration therapy appeared to be well tolerated by children with severe motor disabilities. Total-body bone mineral density increased after 6 months of whole-body vibration therapy. Higher carboxy-terminal telopeptides of type I collagen and lower osteocalcin values indicated that severely disabled children have a reduced capacity for bone acquisition.

Tidskriftsartikel (refereegranskat)abstract
- Background Cervical spondylotic myelopathy (CSM) is the predominant cause of spinal cord dysfunction in the elderly. The patients are often frail and susceptible to complications. Posterior surgical techniques involving non-fusion are complicated by postlaminectomy kyphosis and instrumented fusion techniques by distal junction kyphosis, pseudarthrosis, or implant failure. The optimal surgical approach is still a matter of controversy.Since anterior and posterior fusion techniques have been compared without presenting any superiority, the objective of this study is to compare stand-alone laminectomy with laminectomy and fusion to determine which treatment has the lowest frequency of reoperations. Methods This is a multicenter randomized, controlled, parallel-group non-inferiority trial. A total of 300 adult patients are allocated in a ratio of 1:1. The primary endpoint is reoperation for any reason at 5 years of follow-up. Sample size and power calculation were performed by estimating the reoperation rate after laminectomy to 3.5% and after laminectomy with fusion to 7.4% based on the data from the Swedish spine registry (Swespine) on patients with CSM. Secondary outcomes are the patient-derived Japanese Orthopaedic Association (P-mJOA) score, Neck Disability Index (NDI), European Quality of Life Five Dimensions (EQ-5D), Numeric Rating Scale (NRS) for neck and arm pain, Hospital Anxiety and Depression Scale (HADS), development of kyphosis measured as the cervical sagittal vertical axis (cSVA), and death. Clinical and radiological follow-up is performed at 3, 12, 24, and 60 months after surgery. The main inclusion criterium is 1-4 levels of CSM in the subaxial spine, C3-C7. The REDcap software will be used for safe data management. Data will be analyzed according to the modified intention to treat (mITT) population, defined as randomized patients who are still alive without having emigrated or left the study after 2 and 5 years. Discussion This will be the first randomized controlled trial comparing two of the most common surgical treatments for CSM: the posterior muscle-preser ving selective laminectomy and posterior laminectomy with instrumented fusion. The results of the myelopathy randomized controlled (MyRanC) study will provide surgical treatment recommendations for CSM. This may result in improvements in surgical treatment and clinical practice regarding CSM.

- STUDY DESIGN: Observational cohort study. OBJECTIVE: To evaluate by MRI whether a vertebral fracture during childhood is a risk factor for degeneration of adjacent discs. SUMMARY OF BACKGROUND DATA: Several studies infer that trauma is a major cause of disc degeneration. Only 1 study has by magnetic resonance imaging (MRI) evaluated disc degeneration in children with a former thoracic or lumbar vertebral fracture. That study reported a 50% prevalence of degenerative disc changes 4 years after the fracture. However, due to the sparse literature, it is still unclear whether a vertebral fracture in childhood represents a risk factor for disc degeneration in a long-term perspective. METHOD: Nine boys and 11 girls with a mean age of 12 years (range, 7-16 years) when sustaining a lumbar or thoracic vertebral fracture without neurologic deficits were examined at a mean of 40 years (range, 33-53 years) after the injury. Eighteen of the subjects had 1-column compression fractures, and 2 had Denis Type B burst fractures. All were mobilized without brace or surgery directly after being injured. A favorable long-term clinical and plain radiographic outcome has previously been reported for this cohort. In the present study, the intervertebral discs were evaluated with MRI by applying the Oner classification scheme. Degenerative disc changes were defined as loss of signal intensity on T2-weighted images with or without disc height reduction. RESULTS: Degenerative changes were not more prevalent in discs adjacent to the previously fractured vertebrae than in discs at a distance from those segments. However, there were more Schmorl's nodes at the disc levels adjacent to the earlier fractures. CONCLUSION: Stable vertebral fractures in childhood with no neurologic deficits at injury do not render more degenerative changes than can be expected according to age, but they are associated with more Schmorl's nodes at adjacent disc levels.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To investigate the effects of geriatric rehabilitation on short-term risk of death and readmission after a hip fracture were investigated in a nationwide cohort. In addition, the association of discharge location (nursing home or patient's home) with the short-term risk of death was assessed.DESIGN, SETTING, AND PARTICIPANTS: The cohort consisted of 89,301 individuals at least 50 years of age, with a first hip fracture registered in the Swedish quality register RIKSHÖFT, the years 2004-2012.MEASURES: Short-term risk of death and readmission to hospital after discharge was compared at 8 hospitals, where most patients received inpatient care in geriatric wards, and those treated at 71 regular hospitals.RESULTS: The risks of death within 30 days of admission were 7.1% in patients admitted to geriatric ward hospitals and 7.4% in those treated at regular hospitals (multivariable-adjusted hazard ratio [HR] 0.91, 95% CI 0.85-0.97), whereas the odds of readmission within 30 days of discharge were 8.7% and 9.8%, respectively (multivariable-adjusted odds ratio 0.86, 95% CI 0.81-0.91). The risk of death was influenced by discharge location and inpatient length of stay (LOS). Thus, for patients discharged to short-term nursing homes with a LOS of at most 10 days, each additional day of LOS reduction increased the risk of death within 30 days of discharge by 13% (HR 1.13, 95% CI 1.08-1.18). This association was reduced in patients discharged to permanent nursing homes (HR 1.04, 95% CI 1.02-1.07), and not significant in those discharged to their own home (OR 1.00, 95% CI 0.91-1.10).CONCLUSION: The risks of death and readmission were lower in patients with hip fracture who received care in hospitals with geriatric wards. The risk of death after discharge increased with shorter LOS, especially in patients discharged to short-term nursing homes.

Tidskriftsartikel (refereegranskat)abstract
- Restoration of sensorimotor function after amputation has remained challenging because of the lack of human-machine interfaces that provide reliable control, feedback, and attachment. Here, we present the clinical implementation of a transradial neuromusculoskeletal prosthesis-a bionic hand connected directly to the user's nervous and skeletal systems. In one person with unilateral below-elbow amputation, titanium implants were placed intramedullary in the radius and ulna bones, and electromuscular constructs were created surgically by transferring the severed nerves to free muscle grafts. The native muscles, free muscle grafts, and ulnar nerve were implanted with electrodes. Percutaneous extensions from the titanium implants provided direct skeletal attachment and bidirectional communication between the implanted electrodes and a prosthetic hand. Operation of the bionic hand in daily life resulted in improved prosthetic function, reduced postamputation, and increased quality of life. Sensations elicited via direct neural stimulation were consistently perceived on the phantom hand throughout the study. To date, the patient continues using the prosthesis in daily life. The functionality of conventional artificial limbs is hindered by discomfort and limited and unreliable control. Neuromusculoskeletal interfaces can overcome these hurdles and provide the means for the everyday use of a prosthesis with reliable neural control fixated into the skeleton.
