What is Garden's classification used for which fracture? and explain in detail?
Ans. is 'c' i.e., Neck of femur Garden's classification Garden's classification is the most useful and most accepted classification of the neck of femur. This is based on the degree of displacement of the fracture. Following 4 stages of fracture are there :? 1) Stage 1 : The fracture is incomplete, with head tilted in postero-lateral direction, i.e. into valgus, therefore is known as valgus (abduction) impacted fracture. 2) Stage 2 : Complete fracture but undisplaced. 3) Stage 3 : Complete fracture with paial displacement. 4) Stage 4 : Complete fracture with total displacement. The degree of displacement, in Garden's classification, is judged from change in the direction of medial trabecular stream of the neck, in relation to the bony trabeculae in the weight bearing pa of the head and in the corresponding pa of the acetabulum. i) Stage 1 :- There is an obtuse angle laterally at the trabecular stream. ii) Stage 2 :- Trebeculae between head and neck are broken but they are in alignment with each other and with trabeculae in the acetabulum. iii) Stage 3 :- All three trabeulae are out of alignment. iv) Stage 4 :- Acetabular and head trabeculae are in alignment but head and neck trabeculae are not aligned.
