| Introduction |
 Congenital digital flexion deformity that usually occurs in PIP joints of the small fingers
- caused by abnormal lumbrical insertion/origin or abnormal insertion of FDS
|
| Classification |
|
Camptodactyly classification
|
| Type I |
seen in infancy and affects males and females equally  |
| Type II |
seen in adolescent, affects girls more often than boys |
| Type III |
multiple digits involved, more severe contacture, usually associated with a syndrome |
| Kirner's deformity |
specific deformity of apex dorsal and ulnar curvature of the distal phalanx |
|
| Presentation |
- Physical exam
- very rarely is there significant compromise in function
|
| Treatment |
- Nonoperative
- because only mild impact on function, nonoperative treatment is favored in most cases
- perform splinting and stretching excersises for Type I (infantile)
- Operative
- tendon tenodesis to radial lateral band may be indicated if full active PIP extension can be achieved with MCP flexion
