Summary
This study classifies pelvic obliquity after poliomyelitis into two types and four subtypes based on scoliosis severity and direction. Surgical interventions effectively improved obliquity in most patients, with spinal fusion often needed for severe cases.
Area of Science:
- Orthopedics
- Neurology
- Rehabilitation Medicine
Background:
- Poliomyelitis can lead to fixed pelvic obliquity, impacting patient mobility and quality of life.
- Understanding the classification of pelvic obliquity is crucial for effective treatment planning.
Purpose of the Study:
- To classify fixed pelvic obliquity in post-poliomyelitis patients.
- To evaluate the effectiveness of surgical interventions for pelvic obliquity.
Main Methods:
- Classification of pelvic obliquity into two types and four subtypes based on pelvic level and scoliosis characteristics.
- Surgical procedures included lumbodorsal fasciotomy, abductor fasciotomy, triple innominate osteotomy, transiliac lengthening, and spinal fusion.
Main Results:
- Type I (pelvis lower on short leg) and Type II (pelvis higher on short leg) were identified.
- Subtypes A-D described varying degrees of spinal angulation and scoliosis.
- Surgical combinations improved obliquity in most patients; Type ID and IID often required spinal fusion.
Conclusions:
- A detailed classification system for post-poliomyelitis pelvic obliquity aids in treatment selection.
- Multimodal surgical approaches are effective in correcting pelvic obliquity.
- Spinal fusion is a necessary component for managing severe paralytic scoliosis in specific subtypes.
