Pediatric orthopedics is a branch of orthopedics, and the physical examination of pediatric orthopedics should be carried out in order. Children need to take off their clothes and pants and carefully check the smallest details. The basic inspection methods include: looking, touching, moving and measuring. Mainly from the following aspects: Standing posture and posture: After standing, children should observe their standing posture and posture from the back, front and side, and observe whether there are obvious deformities in the spine and limbs. Gait: The reasons for abnormal gait are muscle weakness, bone and joint deformity, neuropathy, cardiopulmonary diseases, etc. Common typical abnormal gaits include scissors gait, ataxia gait, swinging gait, crossing threshold gait, limping gait (such as limping, limping to avoid pain, limping in gluteus medius) and intermittent limping. Deformity: first determine the type and specific location of deformity, and then measure the limb length and angulation deformity. Joint range of motion: including active and passive range of motion. Examination of muscle strength and muscle tension. Experts suggest that the physical examination of pediatric orthopedics is mainly the examination of spine and limbs, including: seeing, touching, moving and measuring. If children's orthopedic examination is compared with the left and right limbs, or with normal children of the same age, it will be easy to find abnormalities. This contrast principle is very important for parents to check their children initially. Redness, swelling, heat, pain, abnormal shape, deformity, limited joint movement and abnormal gait of children's spine and limbs are all difficult problems in pediatric orthopedics. Parents should find out as soon as possible and go to the pediatric orthopedic clinic for examination in time.
