Nearly 2/3 cervical level injury survivors have C6 root level function
- biceps and wrist extension function
1. Transfer / Triceps
2. Object manipulation
- grip
- key grip / self catheterisation
Consider > 18/12
Allows
- serial evaluation
Restore centre of rotation
Restore acetabular integrity
Component containment
Secure fixation
Know components in situ (esp if leaving femur)
Quantify and grade bone defects
Beware intrapelvic cement / cup (angiogram)
All possible length should be preserved consistent with clinical judgement
- function of amputated stumps decrease progressively with each higher level of amputation
- prosthetic rejection by patient increases with the more proximal amputations
- most ADL'S can be performed adequately with one limb, so don't use prosthesis
- all nerves are drawn distally into wound & sectioned so they retract well proximally to bone level of amputation
1. MFH
2. Liposarcoma
3. Rhabdomyosarcoma (Paediatric)
4. Synovial Sarcoma
5. Leiomyosarcoma
6. Fibrosarcoma
1. Adipose / LS
2 Fibrous / FS
3. Fibrohistiocytic / MFH
Treatment algorithm similar to OS
Overall prognosis similar to OS
- 70% long term survival
A malignant neoplasm composed of small round cells of uncertain histogenesis
Recent data suggests it is of neuroepithelial derivation
