RESUMO
INTRODUCTION: Hallux valgus (HV) is a common condition with impact on pain, function and HrQoL. International consensus does not exist on operative treatment of HV and population-level data regarding surgical treatment of HV is lacking. In this study we aimed to present base-line data from surgically treated HV patients reported to the Swedish register for foot and ankle surgery (Swefoot) during the period 2014-2021. MATERIAL AND METHODS: In total, 7543 feet in 6770 patients were analyzed regarding patient characteristics, grading of HV, surgical procedures and pre-operative PROMs Euroqol-5 Dimension-3 L (EQ-5D-3 L) and Self-reported Foot and Ankle Score (SEFAS). RESULTS: Median age was 55 years (range 15-91) and 87% were women. The surgeon classified 63% of the cases as moderate HV, 15% as mild and 22% as severe. The Chevron osteotomy was the preferred surgical method and was used in 74% of all cases. Out of these, 58% were fixated with a screw. The Offset-V osteotomy was the most performed shaft osteotomy. Proximal osteotomies and lateral releases were less common. The pre-operative mean EQ-5D-3 L index and SEFAS summary score were low and HV patients with overweight and rheumatoid arthritis had significantly lower scores. CONCLUSION: This is the first report from Swefoot describing surgeon- and patient reported pre-operative data in patients with surgical treated HV.

AIM: Individuals with spinal muscular atrophy (SMA) are at risk of developing skeletal problems. This study investigated bone mineral density (BMD), bone turnover markers and motor function in children and adolescents with SMA type 2 and type 3 over a two-year period. The effect of nusinersen was studied in a subgroup. METHODS: Single-centre study, including 20 patients, 2-18 years, of whom ten patients received nusinersen treatment. BMD was measured by dual-energy X-ray absorptiometry. RESULTS: All patients had low BMD levels at baseline; mean Z-score -2.3 for total body less head (TBLH) and -2.9 for total hip left (THL). Significant correlations were found both at baseline and for the follow-up change for motor function and Z-scores (TBLH and THL). For the whole study group, reduced bone formation and unchanged bone resorption, assessed by bone-specific alkaline phosphatase (BALP) (p = 0.0006, ES = -0.83) and C-terminal cross-linking telopeptide of type I collagen (CTX), respectively, were found over the study period. However, BALP decreased less in the nusinersen treatment group, which suggests a positive development on bone mass in these patients. CONCLUSION: Bone health evaluation is important in follow-up programmes for SMA patients. Further investigations are warranted for individuals on survival motor neuron-targeted treatments.

BACKGROUND: Pain is a major symptom in adolescents with hypermobility spectrum disorder or hypermobile Ehlers-Danlos syndrome. Although the underlying mechanism causing generalized pain in children with hypermobility spectrum disorder or hypermobile Ehlers-Danlos syndrome is unclear, central sensitization has been suggested as a possible explanation. The aim of this study was to explore the feasibility of a study protocol for a future case-control study, investigating features of central sensitization in adolescents with hypermobility spectrum disorder or hypermobile Ehlers-Danlos syndrome. METHODS: Central sensitization features were measured in ten patients and nine healthy controls aged 13-17 years via experimental pain measurement quantifying primary and secondary hyperalgesia, endogenous pain modulation, and exercise-induced hyperalgesia. Descriptive statistics were used. Frequency, median, and range values were calculated. RESULTS: Eleven out of 57 patients chose to participate. No control could be recruited through public schools. Therefore, a convenience sampling strategy was used for the recruitment of the control group. The process of assessing primary and secondary hyperalgesia, endogenous pain modulation, and exercise-induced hyperalgesia was well tolerated by all participants (patients and controls). When assessing endogenous pain modulation via conditioned pain modulation, two participants in the patient group and three in the control group did not achieve a pain experience ≥ 3 on the numerical rating scale when immersing their hands in cold water. CONCLUSION: This study investigated the feasibility, safety, and toleration of experimental pain measurements in adolescents with hypermobility spectrum disorder or hypermobile Ehlers-Danlos syndrome. Although the test protocol proved to be sufficiently feasible for use with the participant group, it will need to be adapted in the main study in order to obtain more reliable data. Recruitment, especially of participants for the control group, can be a major obstacle for future studies and requires careful planning. TRIAL REGISTRATION: Researchweb.org, 270,501.

RESUMO
BACKGROUND: Osteoporosis implies an increased risk of complications after orthopedic surgery. For the mostly elderly group of patients undergoing lumbar spinal stenosis surgery (LSS), it is important to include skeletal health evaluation in the preoperative planning. The aim of this study was to assess spine and femoral neck (FN) bone mineral density (BMD) in LSS patients and to evaluate whether the World Health Organization (WHO) fracture risk assessment tool (FRAX) can identify patients with reduced BMD levels in the spine. METHODS: The study involved 65 LSS patients and 53 patients with hip osteoarthritis (HOA) for comparison. BMD was measured with dual-energy X-ray absorptiometry (DXA) in the lumbar spine in three projections: anterior-posterior (AP), lateral and lateral-mid (the mid-portion of the vertebrae), and FN. The LSS patients filled out the FRAX questionnaire. RESULTS: In the LSS group, 43% of the women and 8% of the men were classified as being osteoporotic/osteopenic by AP spine measurement. The corresponding proportions using the lateral spine T-score ≤ - 2.5 were 87% and 57%, respectively, and 82% and 53%, respectively, for the FN. The FN BMD T-score was significantly lower in the LSS group compared with the HOA group. The FRAX questionnaire identified 40% of the LSS patients with a moderate/high risk of sustaining an osteoporotic fracture within 10 years, with or without simultaneous FN BMD, while 71% of these patients were classified as being osteoporotic with DXA lateral spine measurement. CONCLUSION: It is common with osteoporosis/osteopenia in patients undergoing spine surgery, and the identification may influence the surgical treatment why the evaluation of BMD is important preoperatively. FRAX evaluation could not replace DXA measurement of the spine regarding the identification of osteoporosis patients in the preoperative planning phase.

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 < 0.05). 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 (p < 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.

AIM: To investigate the longitudinal development of bone mass in patients with Duchenne and Becker muscular dystrophies and to study the impact of muscle strength and motor function on bone mass in these patients. METHODS: Eighteen patients with Duchenne muscular dystrophy (2.3-19.7 years at baseline) and six patients with the milder Becker muscular dystrophy (10.8-18.9 years at baseline) were followed during a 4-year period with respect to areal bone mineral density (BMD), motor function and muscle strength. RESULTS: Greater bone mineral accretion was observed in the Becker patient group compared with the age-related Duchenne group above 10 years of age, and the older patients with Duchenne experienced decreased femoral neck BMD during the study period. In the study group, significant correlations were found between BMD in the lower extremities and muscle function parameters. CONCLUSIONS: The differences in BMD between patients with Duchenne and Becker as well as between different bone measurement sites demonstrated in the present study point out the importance of preserving muscle strength and motor function in patients with muscular dystrophy. Moreover; it highlights the value of performing region-specific analysis of the bone quality in these patients.

The present study was designed to examine the relationship between bone mineral density (BMD) measurements performed using conventional dual energy X-ray absorptiometry (DXA) in total body (TB), spine, and hip and the more recent technique of DXA with laser (DXL) in the calcaneus in a young population and to explore the diagnostic capacity of the heel DXL. One hundred and twelve persons, 2.2-20.6yr of age, were studied using the 2 techniques. Significant correlations were observed between the heel BMD and BMD values in TB (r=0.73, p<0.001), TB(head excluded(HE)) (r=0.83, p<0.001), spine (r=0.72, p<0.001), and hip (r=0.90, p<0.001). The relationships between DXA and DXL measurements with 95% tolerance intervals are presented. Using heel DXL measurements to predict the lowest DXA quartiles at all the other measured sites revealed sensitivity levels of 0.9 (TB, spine, hip) and 1.0 (TB(HE)) and specificity levels of 0.86 (TB), 0.94 (TB(HE)), 0.92 (spine), and 0.95 (hip). We conclude that BMD values obtained with DXA and DXL correlate well and that the DXA and DXL techniques effectively identify the same individuals with low BMD. The DXL, which is portable, easy to use and gives a low radiation dose, can be useful for assessing bone mass in a young population.

This cross-sectional study examined bone mineral density, bone turnover, body composition and calciotropic hormones in 24 boys with Duchenne muscular dystrophy (DMD) (2.3-19.7 years), most of whom were being treated with prednisolone, and 24 age-matched healthy boys. Our study demonstrated lower bone mineral density in the DMD group for total body, spine, hip, heel and forearm measurements. These differences between DMD patients and controls increased with increasing age. Biochemical markers of both bone formation and resorption revealed reduced bone turnover in DMD patients. The fracture rate was not higher in DMD patients. The DMD group had low vitamin D levels but high leptin levels in comparison with the control group. Muscle strength correlated with bone mineral density assessed at the hip and heel in the DMD group. Interventions that increase bone formation should be considered, as DMD patients have reduced bone turnover in addition to their low bone mineral density.
