1. Equal leg lengths
- goal is mild to moderate isolated discrepancy
2. Unequal leg lengths
- goal with paralysis / equinus foot
- aim 1-2 cm short for clearance
3. Level Pelvis
- should use blocks to estimate functional correction
4. Vertical LS Spine
- vertical spine more important than level pelvis
Metatarsus varus
- adduction of the forefoot at the TMTJ
Intrauterine positional deformity / packaging defect
1:1000
- M = F
- bilateral in 50%
- 10% have CDH
Unclear
Theories
- intrauterine positioning defect
- prone nursing
Painful restriction of dorsiflexion of the great toe
- secondary to degenerative changes in MTPJ
- initially pain and synovitis
- osteophytes don't form medially or on plantar aspect
Two peaks

2. Middle Age M > F
