33. Palmer Classification
Class 1: Traumatic Injuries
A Central perforation of the disk proper
B Peripheral avulsion from the ulna
Without styloid fracture
With styloid fracture
C Distal avulsion from the carpus
D Radial avulsion
Without sigmoid notch fracture
With sigmoid notch fracture
Class 2: Degenerative Injuries
A TFCC wear
B TFCC wear + lunate and/or head chondromalacia
C TFCC perforation + lunate and/or head chondromalacia
D TFCC perforation + lunate and/or head chondromalacia +
lunotriquetral ligament perforation
E TFCC perforation + ulnocarpal arthritis

N.D
36. 1. Central TFCC lesions
⢠Poorly vascularized- healing potential minimal
⢠Arthroscopic debridement up to 2/3 of articular disc
37. 1. Central TFCC lesions
Arthroscopic TFCC debridement using radiofrequency probes
Darlis NA & Sotereanos DG, JHS(B)2005
38. 1. Central TFCC lesions
⢠Often degenerative and associated
with ulnocarpal impaction
syndrome
⢠Ulnar recession procedure to
prevent symptom recurrence
39. Ulnocarpal Impaction Syndrome
Clinical features:
⢠Ulnar sided wrist pain
⢠Associated degenerative changes:
â Ulnar side of the lunate
â Radial side of the ulnar dome
â TFCC central tear
â Triquetrum- LunoTriquetrum lig.
⢠Usually positive or neutral ulnar variance
49. Common misconceptions
⢠TFCC tear â DRUJ instability
â In fact: most tears do not have evident instability
⢠Ulnar styloid fracture â DRUJ instability
â Styloid fractures may co-excist with TFCC tears
50. Timing of the repair
