Growth Abnormalities in Amputation Stumps in Children
- See: Pediatric BKA:
- Overgrowth Phenomena:
- occurs as a result of appositional growth (not physeal growth);
- in order of frequency it occurs in the: humerus, fibula, tibia, and femur;
- hemiatrophy of pelvis associated with coxa valga and elongation of lesser trochanter; femur and ilium usually smaller than on normal side;
- overgrowth of bone in relation to the skin;
- Below Elbow Amputation:
- pincerlike contour from overgrowth of radius in relation to ulna
- tilting of proximal radial epiphysis may occur;
- overgrowth of ulna with subcutaneous projection;
- Terminal BEA:
- is the most common congenital amputation;
- use of a passive device at 3-6 months for unilateral UE amputations (fit when they sit);
- Above Elbow Amputation:
- humeral Varus;
- overgrowth of humerus in relation to skin, causing subcutaneous projection;
- Children: Disarticulations:
- deficient growth in residual limb (growth discrepancy) will convert anatomic disarticulation to the next highest level;
- ankle disarticulation becomes functional AK, etc, if child is young;
- for older child, consider epiphyseal arrest (eg distal femur), at just right time to give 1 or 2 inches of shortening;
- what appears to be a very long above the knee amputation is a small child can result in a very short limb that is actually difficult to
fit w/ a prosthesis at skeletal maturity;
- Misc: it is important to take out periosteum below the area of osteotomy
