Patient-reported outcome after hallux valgus surgery - a two year follow up

BACKGROUND

Patients with hallux valgus deformity may require surgery but prospective patient-reported data is scarce.

METHODS

We evaluated 53 patients with a mean age of 55.3years (SD 14.1, 50 women), who underwent surgery due to hallux valgus. They completed the PROMs SEFAS, EQ-5D and SF-36 before and 6, 12 and 24 months after surgery.

RESULTS

All patient-reported outcomes improved at 6, 12 and 24months compared with the preoperative status. The greatest improvement occurred at 6months: SEFAS Δ 10.0 (95% confidence interval 7.8-12.2), EQ-5D Δ 0.22 (0.15-0.29), EQ-VAS Δ 8.4 (4.4-12.4), PF SF-36 Δ 22.0 (14.6-29.3) and BP SF-36 Δ 30.6 (23.1-38.1).

CONCLUSIONS

Hallux valgus surgery considerably reduced pain and improved function already within 6months after surgery. The improvement between 6 and 24months' follow-up was minimal measured with PROMs.

LEVEL OF CLINICAL EVIDENCE

III - prospective observational cohort study.

Extended physical education in children aged 6-15 years was associated with improved academic achievement in boys

AIM

Physical activity (PA) has been associated with enhanced cognition, brain development and concentration. This study evaluated whether increased physical education (PE) improved academic achievement.

METHODS

We recruited 304 children (55% boys) from a Swedish school in Skane County in 1998-2002 when they were six to seven years of age and followed them through all nine mandatory school years. Their PE level was increased from 60 to 200 minutes per week, and their results were compared with 73 885 control children (51% boys) in the county who graduated in the same years and did the standard 60 minutes of PE per week. Their academic achievements were measured as their final grade scores and the proportion of students eligible for upper secondary school.

RESULTS

The eligibility for further education increased in the intervention boys by 6.8 percentage points and the mean grade score by 12.1 points, while in the control group as a whole, the eligibility rate decreased by 0.7 percentage points and the mean grade score increased by 1.7 points. No changes in eligibility rates or mean grade scores were seen in the intervention girls.

CONCLUSION

Increasing weekly PE over nine years was associated with improved academic achievement in boys.

The associations of physical activity with fracture risk--a 7-year prospective controlled intervention study in 3534 children

SUMMARY

This is the first study indicating an association between gradually diminished risk of fractures and years of increased physical activity. Our results could imply great benefits not only for the individual but also for the healthcare burden and cost of society.

INTRODUCTION

Physical activity (PA) in childhood is associated with high bone mass and beneficial neuromuscular function. We investigate if increased PA also is associated with fracture risk.

METHODS

We registered fractures in 3534 children aged 6 to 8 years at study start for up to 7 years; 1339 with 40 min of moderate PA every school day (intervention) and 2195 with the Swedish standard curriculum of 60 min of PA per school week (controls). In a subsample of 264 children, we measured areal bone mineral density (aBMD; g/cm(2)) with dual-energy X-ray absorptiometry (femoral neck and total spine) and muscle strength (peak torque for knee extension and flexion; Nm) with computerized dynamometer at baseline and after 7 years. We estimated annual fracture incidence rate ratios (IRR) in the intervention group compared to the control group as well as changes in bone mass and muscle strength. Data is given as mean (95% CI).

RESULTS

The IRR of fractures decreased with each year of the PA intervention (r = -0.79; p = 0.04). During the seventh year, IRR was almost halved [IRR 0.52 (0.27, 1.01)]. The intervention group had a statistically significant greater gain in total spine aBMD with a mean group difference of 0.03 (0.00, 0.05) g/cm(2) and peak flexion torque 180° with a mean group difference of 5.0 (1.5, 8.6) Nm.

CONCLUSIONS

Increased PA is associated with decreased fracture risk, probably in part due to beneficial gains in aBMD and muscle strength.
