The
Signs |
| 3 |
|
Rigidity
of Equinus (RE) (Figs. 9a, b, c) |
| |
|
This
sign is a measure of the posterior contracture.
The more the residual posterior contracture, the
less the foot will dorsiflex. |
| |
|
|
| |
|
| Fig.
9a |
 |
|
With
the knee held in full extension and the foot
slightly inverted, the ankle is dorsiflexed
as much as possible gently. The RE sign is
scored 0 when the ankle dorsiflexes fully
(the dorsum of the foot almost touches the
front of the shin.) |
|
| |
|
|
| |
|
| Fig.
9b |
 |
|
The
RE sign is scored 0.5 when the ankle dorsiflexion
is not full but sufficient to allow the lateral
border of the foot to make an angle of 90
degrees or less with respect to the long axis
of the leg as viewed from the lateral side. |
|
| |
|
|
| |
|
| Fig.
9c |
 |
|
The
RE sign is scored 1 when the ankle dorsiflexion
is severely limited and the lateral border
of the foot makes an angle of greater than
90 degrees with respect to the long axis of
the leg as viewed from the lateral side. |

Curvature
of the Lateral Border of the foot (CLB, Figs. 10a,
b, c) |
| |
|
The
lateral border of the foot is normally straight.
A curved border implies medial contracture. The
amount of curvature can indicate the amount of medial
contracture. |
| |
|
|
| |
|
| Fig.
10a |
 |
|
Examine
the plantar surface of the foot and gauge
the curvature of the lateral border. Normally
the lateral border of the foot is straight
from the heel to the head of the 5th metatarsal.
A straight edge placed along the lateral border
of the calcaneus may assist in the estimation
of the curvature. A straight lateral border
of the foot is given a score of 0. |

|
| Fig.
10b |
 |
|
In
the abnormal foot the lateral border of the
forefoot moves away from the straight edge.
A mildly curved lateral border is scored 0.5
(the curvature appears to be in the distal
part of the foot in the area of the metatarsals) |
| 0.5 |
|
|
|
| |
|
|
| |
|
| Fig.
10c |
 |
|
A
pronounced curvature of the lateral border
is given a score of 1. (The curvature appears
to be at the level of the calcaneocuboid joint.) |
