Tibial shaft Fractures.
Ankle fractures.
Mechanism of fractures
• Lower limb fracture is a result of a high
energy trauma except in elderly people or
diseased bones
• Types of fracture are depend on position of
limb during impaction and magnitude of
forces applied.
Management
• The proper way to treat a patient with high
energy trauma is to look at the patient as
whole ,not to injured limb alone!
• So the aim to treat such patient is to save life
first, then save limb ,finally to save function.
• A.B.C.D
Pelvic Fractures
• Pelvic fracture is a high energy trauma , as a
result of MVA, fall .
• Classifications. ( Tile)
Type A. Stable
A 1. fractures of the pelvic not involving the
Ring.
A 2 . Stable , minimally displaced fracture of
the Ring .
Type A stable fracture the SP not
disturbed
• Type B. Rotationally Unstable ,Vertically
Stable.
B1. Open Book
B2 . Lateral Compression : Ipsilateral
B3. Lateral Compression :Contra lateral
Type B open book fracture Diasthesis of SP more
than 2cm
• Type C. Rotationally and Vertically Unstable
C1 . Unilateral
C2 . Bilateral
C3 . Associated with Acetabular Fracture
Type c fracture there is diasethsis of SP & vertical shear
& SIJ involvement
MANEGEMENT
•
•
•
•
Aggressive treatment . By A.B.C.D.
Obtain X-Ray: AP pelvic, Inlet ,outlet ,Ct Scan.
Think in systemic approach.
Specific treatment:
type A . symptomatic treatment
type B .ORIF with plates& screws ,External Fix.
Type C . ORIF with plates & screws. Both AP.
Type A stable Fracture of superior & inferior pubic remi
& no diasthesis of SP

Surgical correction of type B open book fracture by
anterior plating [ ORIF ]
CT give you clear idea about bony & soft tissues you
can asses the degree of distrubtion

posterior of LT SIJ
Surgical correction of type C fracture by percutanous
screw & plating of SP anterior[ ORIF ]
Acetabular fracture
• Usually it is a result of high- energy trauma .
• The acetabulum is divided into 4 segments—
an anterior column and wall (rim) and a
posterior column and wall (rim). Fractures of
the acetabulum are classified based on their
involvement of these structures .
classification Letournel and Judet
Investigation
• AP pelvis.
• Judat views ( Internal Oblique,Obturator view)
• C T scan .

1\ ! Amount of post. Wall

2\ intra-articular fragments
3\ impaction on post. Wall
4\ sublaxation of ! joint or
dislocation
All these are indications for
operation ( ORIF )

TREATMENT
• Indications for Nonoperative Treatment
1. Nondisplaced and Minimally Displaced
Fractures.
2. Fractures with Significant Displacement but in
Which the Region of the Joint Involved Is Judged
To Be Unimportant Prognostically
• 3.Secondary Congruence in Displaced BothColumn Fractures
• Medical Contraindications to Surgery
• Local Soft Tissue Problems, Such as Infection,
Wounds, and Soft Tissue Lesions from Blunt
Trauma.
• Elderly Patients with Osteoporotic Bone in
Whom Open Reduction May Not Be Feasible.
• skeletal traction for 4-6 weeks. And then start
physiotherapy in bed , PWP ,FWBAT.
Operative Treatment
• Indications for Operative Treatment.
1. An acetabular fracture with 2 mm or more
displacement in the dome of the acetabulum.
2. any subluxation of the femoral head from a
displaced acetabular fracture noted on any of
the three standard roentgen graphic views
• More than 50% involvement of the articular
surface of the posterior wall or clinical
instability with hip flexion to 90 degrees in
posterior wall fractures .
• Incarcerated Fragments in the Acetabulum
after Closed Reduction of a Hip Dislocation.

complications
• posttraumatic arthritis in 17%.
• a vascular necrosis after posterior dislocation
was 7.5%.
• Infections are reported to occur in 1% to 5%
• Sciatic nerve palsies as a result of the initial
injury occur in approximately 10% to 15%.
• Heterotopic ossification (HO) occurs after
most extensile approaches
HIP Dislocations
Bilateral post. dislocation
Post.dislocation of
RT hip for pt with
THR
Proximal femoral fracture.
• Fractures of the proximal femur are classified
first according to their anatomical location.
• Femoral neck fractures and intertrochanteric
fractures occur with about the same
frequency.
• They are both more common in women than
in men by a margin of three to one.
• it is a result of MVA, Fall,

Treatment
neck of femur
• Nondisplaced fracture of neck of femur can
be treat with canulated screws.
• Displaced fracture ----------DHS in patient less
than 60 years.
• > than 65 years look for.
. Level of activities.
. Status of the acetabulum.
then chose THR vs. hemi arthoplasty.
Treatment
• Intertrochantaric fracture-------DHS . DCP.
• Subtrochantaric fracture---------DHS.ABP.DCP.
• Combination of both------- IM Nail with
Canulated srews.
