Introduction
It is important to appreciate that not all paediatric deformities, especially of the lower limbs, are pathological. Quite a few of them are physiological and they are referred to as normal variants of lower limb development. These generally spontaneously get better as the child grows. It is important to differentiate normal variants from pathological conditions that present in a similar fashion. The following table provides some differentiating factors:
Physiological Conditions | Pathological Conditions |
Usually symmetrical | Rarely symmetrical |
Flexible deformity – correctable | Rigid deformity |
Familial (family history positive) | Family history positive or negative |
Improves with time | Usually worsens with time |
No active treatment generally necessary | Intervention is almost always needed |
Physiological deformities/normal variants are an important cause of parental concern.
A detailed history and full clinical examination are generally all that is required to differentiate pathological conditions from normal variants.
What ages do the different normal variants present?
From birth to the first 2 years of life, the following normal variants are present:
- Packaging deformities
- Physiological flat foot (pes planus)
- Physiological bow legs (genu varum)
From 2 years right up to the adolescent age (puberty), the following normal variants are present:
- Knock knees (genu valgum)
- In-toeing
- Out-toeing
What are packaging defects?
Normal variants which are the result of intrauterine moulding are called packaging deformities. These include:
- Hyper-extension of the knee
- Postural talipes/calcaneovalgus foot
- Out-toeing of infants as a result of external rotator contracture
- Metatarsus adductus
Below is the brief description of some of the above deformities.
In-toeing and out-toeing
In-toeing, most commonly known as pigeon toes (Figure 1.1), refers to an inward pointing foot and is more common than out-toeing (foot points outwards) (Figure 1.2). They are an important cause for parental concern and a frequent referral to paediatric orthopaedic...
