A disadvantage of an anterolateral incisional approach to the femoral shaft is
The vastus lateralis is incised requiring longer rehab; increased pain and bleeding
The blood supply is introduced to the medullary canal through what structure?
nutrient foramen
Identify the stage of bone healing that is bypassed when compression plate fixation is employed.
callous
What muscle is located directly underneath the iliotibial band?
vastus lateralis
What muscle is located between the vastus lateralis and the femoral shaft?
vastus intermedius
When using the posterolateral incisional approach, which muscles are retracted anteriorly to expose the fracture site?
vastus lateralis and vastus intermedius
The soft outer layer of the bone provided blood supply to the cortex and is called the
periosteum
The linea aspera is a ridge of bone located on the
posterior aspect of the femoral shaft
Name a disadvantage of ORIF with plating technique.
additional soft tissue trauma due to open surgical intervention
The major vessels are located on which aspect of the thigh at the mid-shaft level?
medial
What might contraindicate medullary rodding?
the proper positioning for rodding of the multiple traumatized patient may not be feasible
Name an indication for treating a mid-shaft fracture of the femur with compression plating.
*third degree open fracture with a compromised blood supply
*multiple trauma
*no access to rodding system or the correct sized rod
Poor results from plating usually occur because of
*poor selection of plate size
*screws don't go through both cortices
*inadequate compression
Non-union can be caused when bone graft isn't used to fill a bony deficit at the fracture site.
*True or False
True
Drilling through the femoral shaft correctly is evidenced by what kind of feedback?
A distinct tactile feeling that the drill bit is contacting hard lateral cortex, soft medullary canal, hard medial cortex, and finally the soft tissue of the medial thigh
Why might a surgeon choose to put he end screws of the plate thorugh only one cortex?
to decrease stress concentration on the bone at the ends of the plate
How much of the total stress (weight) is delivered across the femoral fracture when using a compression plate?
30%
What party of the femur articulates with the tibia and patella?
femoral condyles
What constitutes an open or compound fracture?
the broken bone punctures through the skin
Identify the main artery of the thigh.
femoral
A cross section of the mid-shaft of the femur would appear
triangular
The branches of the deep femoral artery that travel posterior to the femur and pierce muscles and intermuscular septums are called the
perforators
___Compression is a force that changes with the changing outside forces presented to the fracture site.
Dynamic
Identify the type of fracture that has more than two fragments.
comminuted
The part of the femur that articulates with the acetabulum is the
femoral head
The acronym NAVEL refers to the anatomical placement of the nerve, artery, vein, empty space, and lymph node in the femoral triangle.
*true or false
true
Identify the soft osseous material filling the cavities of the cancellous bone.
marrow
This tissue is concerned with the formation f red blood cells.
red marrow
This tissue contains fat cells.
yellow marrow
What condition can be postop complication of compression plating?
localized osteoporosis
Musculoskeletal assessment of the patient with a mid-shaft fracture of the femur includes
*Absent or decreased pulses
*capillary refill
*generalized edema
*ecchymosis
In the patient with a fractured femur, the RNFA will
*examine the patient for possible associated injurieds to the knee and hip
*Anticipate extensive soft tissue injury
*examinethe patient for possible injuries to the sciatic nerve and superifiial femoral artery and vein
