Don’t delay necessary treatment just to “wait until exams are over”; certain treatment windows depend on bone growth, not exam schedules

Scoliosis is a sideways bend of the spine. A brace is a hard shell vest that holds the spine. Worn while bones are still growing, 75% of children never reach a 50-degree curve by the end of growth; observation alone is only 42%. The wearable window follows when bones finish growing, not the high-school or college exams — wait until after exams and you may miss it.

Cost

No monetary cost involved. This point concerns whether to start treatment early or late, not expense. Taking time off school and returning for follow‑ups do cost time, while the actual cost of treatment is separate. The real challenge is that braces must be worn at least 18 hours a day, which can be uncomfortable for kids.

Benefit

A multi-hospital trial enrolled 242 adolescents with idiopathic scoliosis who met criteria for bracing. Of these, 116 were assigned by lot and 126 chose for themselves whether to wear a brace. Success and failure were defined in advance: curve reaching 50 degrees or more was failure; still below that at skeletal maturity was success. Brace-group children were asked to wear at least 18 hours a day. Results were analyzed by initial assignment, whether or not they actually wore enough. Assigned brace group success 75%, assigned observation only 42% (odds ratio OR 4.11, 95% CI 1.85–9.16). Combining the lot-assigned and self-chosen groups: 72% versus 48% (after leveling baseline differences, odds ratio OR 1.93, 1.08–3.46). More hours worn per day meant higher success (P<0.001; this link is unlikely to be chance). The trial stopped early because the brace worked

Book note

Scoliosis is the example here because it has lot-assigned trials and a clear time window. It is also a focus item on student health checks (see item 7). In the author’s experience, similar cases include strabismus, amblyopia, dental caries, and congenital heart disease surgeries that can be timed. The later they are done, the worse the result may be, or the higher the cost. This section did not verify each one; ask a specialist about the exact window. If missing class is the fear, during compulsory education a leave of absence can last up to 1 year with enrollment kept — see item 11.
