Classification of Boyd and Griffin for Trochanteric Fractures

Boyd and Griffin classified femoral fractures involving the region of the greater and lesser trochanters.

Primary Features	Comminution	Type
simple linear fracture involving the greater and lesser trochanters (along the inter-trochanteric line)	absent	Type I
comminuted fracture involving the greater and lesser trochanter; the main break is along the intertrochanteric line but with multiple cortical breaks	present	Type II
fracture line at or just below the level of the lesser trochanter; may be mixed with features of Type I or Type II fractures	absent or present	Type III
comminuted fracture involving the trochanters and extending into the femoral shaft; fracture lines are usually present in 2 or more planes	present	Type IV

where:

• The Type III fracture can be classified as a subtrochanteric fracture.

Type	Reduction
Type I	simple
Type II	variable; may be very difficult
Type III	usually more difficult than Type I or II
Type IV	may require fixation in 2 planes
