• type 3: frag off distal aspect of sesamoid bone
• type 4: frag within distal sasmoidean lig
• good for type 1 and 2

Question 2

Tx of OC

Answer 2

Note can also get subcondral cyst here

Answer 3

• type 1: subcondral flateening
• 2: flattening with bony frag
• 3: loose osseous body
• rest for type 1, debride for 2+3
• good

Question 4

• prognosis

Answer 4

• lateral trochlear ridge: OCD

Tx and prognosis for diff tendon injuries:

1) SDF
2) DDF tendinitis
3) Suspensory desmitis
4) Distal check desmitis
5) Distal sesamoid Desmitis

Answer 8

1) Palmar annular desmotomy
- guarded, freq reoccurance
2) palmar annular desmotomy, shoeing
- guarded
3) fenestration, retinacular release, neurectomy of deep branch of lateral plantar n. if chronic
- varies
4) IC desmotomy, distal check desmotomy if chronic
- fair-good if early, guarded is chronic or severe
