The document classifies pelvic fractures, femoral head fractures, and femoral neck fractures into different types based on their stability and location of the fracture. Pelvic fractures are classified into Type A (stable), Type B (rotationally unstable, vertically stable), and Type C (rotationally and vertically unstable). Femoral head fractures are classified into Type I, II, III, and IV based on the location of the fracture relative to the fovea capitis femoris and presence of other fractures. Femoral neck fractures are classified into three types based on the location of the fracture relative to the lesser trochanter.

2.  Type A Stable
 A1: Fractures of the pelvis not involving the ring;
avulsion injuries
 A2: Stable, minimal displacement of the ring

3.  Type B: Rotationally unstable, vertically stable
 B1: External rotation instability; open-book injury
 B2: LC injury; internal rotation instability; ipsilateral only
 B3: LC injury; bilateral rotational instability (bucket
handle)

4.  Type C: Rotationally, and vertically unstable
 C1: Unilateral injury
 C2: Bilateral injury, one side rotationally unstable, with
the contralateral side vertically unstable
 C3: Bilateral injury, both sides rotationally and vertically
unstable with an associated acetabular fracture

5. Type I: Hip dislocation with fracture of the femoral head
inferior to the fovea capitis femoris
Type II: Hip dislocation with fracture of the femoral head
superior to the fovea capitis femoris

6. Type III: Type I or II injury associated with fracture of the
femoral neck
Type IV: Type I or II injury associated with fracture of the
acetabular rim

7.  Type1- undispalced, uncommunited
 Type 2- displaced, minimal communition, lesser
trochandric #, with varus
 Type 3- displaced, communited, grater trochandric #,
varus
 Severe communition, subtrochandric extension, also
reverse oblique # line.

8.  Type I: At the level of the lesser trochanter
 Type II: <2.5 cm below the lesser trochanter
 Type III: 2.5 to 5 cm below the lesser trochanter
