Amputations

Indications

 

1. Congenital Limb Deformity

- 60%

- rare for UL

- PFFD / Tibial Hemimelia

 

2. Tumours 

 

3. Trauma 

- 26%

 

Considerations

 

Growth

 

Diaphyseal amputation removes one of physes

- progessive LLD

 

Aims

 

1. Preserve physis via disarticulation

2. Preserve as much bone length as possible

 

Overgrowth

 

Terminal overgrowth of stump

- occurs when appositional growth of bone exceeds that of surrounding soft tissues

- may result in penetration of bone through skin

- occurs in 10%

- most common in humerus, fibula, tibia & femur

 

Treatment

1. Stump revision with adequate resection of bone + myoplasty

2. Autogenous osteochondral stump capping 

 

Phantom Limb sensation

 

Always occurs in children

- < 10 years old settles rapidly

- not painful usually

 

Prosthetics

 

Should coincide with normal motor skill development

 

Upper limb

 

Age 4-6 months

- when sitting balance required

- passive terminal device

 

Age 2-3 years

- add active cable control with voluntary terminal opening device

- when starts object manipulating with terminal device

 

Lower Limb

 

Age 8-12 months

- terminal device

- for AKA, add knee device when child walking well

 

Age 5-6 years

- more elaborate devices

- gait retraining
