Treated by Dr. Venkat Ram Thyalapalli at Dr Venkatram Thyalapalli
Perthes Disease, also called Legg-Calvé-Perthes disease, occurs when the blood supply to the rounded head of the thigh bone (femoral head) is temporarily interrupted. This causes the bone tissue to break down and weaken. The condition most commonly affects children between ages 4 and 8, and the hip gradually heals over time as new blood vessels form and the bone rebuilds itself. Dr Venkatram Thyalapalli offers evaluation and management to support the healing process and protect hip function.
Involves less than half of the femoral head, generally with a favourable outlook and often managed with observation.
Affects a larger portion of the femoral head, with moderate changes to bone shape and density; treatment depends on age, symptoms, and hip containment.
The entire femoral head is involved, carrying higher risk of deformity; close monitoring and sometimes surgical containment may be considered.
Multiple factors can contribute to the development and progression of this condition.
Recognising the signs early gives you more treatment options.
Assessment begins with the child's history—including when symptoms started, activity level, and family history—and a physical examination of hip movement and walking pattern. X-rays help confirm the diagnosis and stage of the disease; MRI may be used in early or uncertain cases. Not every child requires MRI or repeated imaging.
From conservative to surgical — we always start with the least invasive option first.
A structured, patient-first approach from first visit to full recovery.
Dr Venkatram Thyalapalli listens to when the limp or pain started, reviews the child's activity level, and examines hip movement, leg length, and walking pattern.
X-rays are used to confirm the diagnosis and determine how much of the femoral head is affected. MRI may be arranged if the disease is suspected early or if X-rays are inconclusive.
Based on the child's age, stage of disease, and hip containment, a plan is developed—ranging from observation and activity adjustment to physiotherapy, bracing, or, where indicated, surgical containment.
Regular follow-up appointments track healing through the fragmentation, re-ossification, and remodelling phases. Adjustments to activity, exercises, or bracing are made as the hip recovers, and families receive clear guidance at each stage.
What to expect at each phase of recovery.
The femoral head softens and begins to break down. Treatment focuses on protecting the hip, maintaining range of motion, and keeping the bone well-seated in the socket. Activity is restricted, and regular imaging monitors progress.
New bone starts to form and the femoral head gradually hardens. Clinical and X-ray follow-up continues; activity is slowly increased as healing advances. Physiotherapy remains important to preserve movement.
The bone reshapes itself as the child grows. The goal is a rounded femoral head that fits well in the socket. Long-term follow-up assesses final hip shape and function; some children may have residual stiffness or leg-length difference.
Good management aims to keep the femoral head well-covered during healing, supporting a rounder final shape and better long-term hip function. Outcomes depend on age at onset, extent of involvement, and response to treatment.
Regular exercises and activity modification help maintain hip flexibility. Some children may still develop mild stiffness or reduced rotation, which can affect certain movements.
Many children resume normal activities and sports after healing is complete. The timeline varies; some may need to avoid high-impact activities for an extended period.
Despite treatment, some children—particularly those with extensive involvement or older age at diagnosis—may have a permanently flattened or irregular femoral head. This can increase the risk of hip arthritis in adulthood, and long-term monitoring may be advised.
Without appropriate care, the femoral head may heal in a flattened or irregular shape, especially if it is not well-contained in the socket. This can lead to poor hip mechanics, early-onset arthritis, stiffness, and pain in adulthood. Early recognition and management aim to guide the healing process and reduce the risk of long-term complications.
Seek evaluation if your child develops a limp—even if painless—or complains of hip, groin, or knee pain that does not improve with rest. Early assessment allows timely diagnosis and the opportunity to protect the hip during the critical healing phases. Prompt care is especially important for younger children and those with progressive symptoms.
Early treatment means more options and better outcomes. Book a consultation to understand your condition and explore the right path forward.
