Bowing of the legs in rickets

Bowing may improve as healthy bone growth resumes, but the outlook depends on the cause, the child’s stage of growth, and how established the deformity is.

Rickets disrupts mineralisation at growing bone and growth plates. Legs may bow outward, and some children also have bone pain, muscle weakness, delayed movement skills, widened areas near joints, or a different walking pattern. Bowing itself does not reveal why rickets developed.

Clinicians examine growth, gait, leg symmetry, joints, and other skeletal signs. Blood tests and imaging can help distinguish nutritional deficiency from absorption, kidney, genetic, or metabolic causes, because management differs between them.

Have suspected rickets assessed by a paediatric clinician rather than starting high-dose supplements independently. Treatment is tailored to the identified cause and may include prescribed vitamin or mineral replacement alongside management of an underlying disorder.

Follow-up checks growth, symptoms, laboratory results, and leg alignment. Physiotherapy may support strength, movement, and safe activity, but cannot correct active mineralisation problems. Bracing is not suitable for every pattern. Persistent major deformity may later need specialist orthopaedic planning after the bone disease is controlled.

Arrange prompt medical review if a child’s bowing is progressing, differs clearly between the legs, or occurs with bone pain, weakness, delayed walking, poor growth, or repeated fractures. Seek urgent care if the child suddenly cannot stand or walk, has severe pain after minor force, or has a visibly injured limb.

Ask what type of rickets is suspected, which tests will identify the cause, and how treatment response will be tracked. Clarify whether current activities are safe, whether a physiotherapist should assess development, and when persistent bowing warrants review by a paediatric orthopaedic surgeon.
