Intoeing gait

Intoeing gait

Intoeing is defined as a negative foot progression angle and results from one or more lower limb torsional anomalies ( Figure 44.1 and Table 44.2 ). Persistent femoral neck anteversion presents clinically with excessive internal rotation at the hip joint, which is best assessed with the patient pr one ( Figure 44.2a ). All femurs are anteverted at birth but as the femur lengthens it rotates with spontaneous improvement in the anteversion. If, by 10–12 years, a persistent deformity is associated with functional di ffi culties, corrective osteotomy may be justified. In such cases, the child has no ability to externally rotate the extended hip. In others, compensatory external tibial torsion may develop, in which case the foot progression angle will be normal but the child may have symptoms of the miserable malalignment syndrome, including knee pain and feelings of instability . Internal tibial torsion is assessed by the thigh–foot angle and is commonly associated with physiological tibia vara in infants ( Figure 44.2b ). Spontaneous correction occurs by age 4, as the tibia rotates with growth. Metatarsus adductus ( Figure 44.2c ) is usually flexible and corrects by age 2–4 years. For the more rigid foot, stretching, Surgical release is rarely indicated.

Extoeing is less common but results from relative femoral retroversion, external tibial torsion or flexible flat feet. The child may walk late because of poor balance associated with the foot posture and overall alignment. Gait improves with growth/time. T oe walking is a phase in normal gait development. If the gait does not mature to a heel–toe pattern by 3 years, physiotherapy may help, and older children benefit from surgical lengthening of a contracted gastrocsoleus complex, if it is present. If toe walking starts after walking age, a spinal or neuromuscular aetiology such as a tethered cord or a muscular dystrophy must be considered; in the unilateral case, an orthopaedic cause for a short leg, such as a dislocated hip, must be excluded.
