How Would you code this?????


PROCEDURE

1. Complex open reduction and internal fixation of periprosthetic

fracture, right femur.

2. Bone grafting, right femoral shaft fracture.




PREOPERATIVE DIAGNOSIS: Periprosthetic femur fracture.




POSTOPERATIVE DIAGNOSIS: Periprosthetic femur fracture.




INDICATIONS: A 52-year-old female with multiple medical problems

including end-stage hemodialysis. She multiple previous orthopedic

procedures including a previous trochanteric nail done elsewhere which

was converted by myself to a complex primary total hip. She was doing

well with this but had some type of twisting injury about 2-3 months

ago and only presented in the office 2 days ago with pain over the

thigh. Subsequent workup showed that there was a violation of the

cortex at the tip of the stem.




OPERATIVE FINDINGS: There was violation of the cortex at the tip of

the stem, but the stem itself was felt to be stable and thus was not

changed. Overall bone quality was poor, as expected, because even

though she is 52, she is a much older 52-year-old due to her multiple

medical problems and osteoporosis.




ANESTHESIA: General.




BLOOD LOSS: About 800 mL.




IMPLANT SYSTEM USED: Zimmer 10-hole periprosthetic plate. We used, I

believe, 7 cables and 4 screws.




COMPLICATIONS: None.




DRAINS: x1.




NOTE: This case was significantly more difficult than normal due to,

first, the patient's large leg size. There was at least 6 inches to

negotiate from the skin down to the femur. In addition, her overall

protoplasm and tissues were poor due to her multiple medical problems

which led to more bleeding than is usual and overall friability of the

tissues. In addition, the type of fracture was certainly difficult and

required grafting of an allograft strut as well.




DESCRIPTION OF PROCEDURE: The patient was taken to the operative

theater and placed supine on the table. After general anesthesia was

obtained, Bier blocks were given. She was placed in a lateral

decubitus position on the pegboard. Care was taken to pad all bony

prominences. The leg was prepped, washed, and draped in normal sterile

fashion. A timeout was done. A long lateral incision was then used,

incorporating the previous incision and extending distally. We opened

up down to the level of the vastus and split that in the normal

fashion and exposed the fracture. There was relatively consistently

oozing and bleeding throughout the case. We just did our best to

maintain hemostasis using a combination of packing, thrombin, Gelfoam,

Surgicel, and other appropriate hemostatic techniques.




The fracture was encountered and irrigated. I tested the stem through

it, and it was stable. We opened up an allograft tibial strut,

because I felt the strongest construct, given her poor quality of

bone, would be to place a strut over the fracture site, more on the

medial aspect, and to place the plate laterally. In addition, this

would allow me to tension the cables firmly without necessarily

pulling them through her osteoporotic bone. I prepared the allograft

with a bur on the back table. We then fixed it and placed our plate

and were able to get 2 cables around it initially. I then placed 2

screws distally, multiple cables proximally, and several cables more

along the allograft. I was taking intraoperative fluoroscopy pictures

of the AP and lateral periodically, and I was very happy with the

final construct. Everything moved as 1 unit. The hip remained reduced,

and the fracture was stable with this hardware. As such, attention

turned towards closure.




The wound was copiously irrigated. I placed a deep Hemovac drain. The

vastus was closed with a running #1 Ethibond suture, the tensor with

an interrupted figure-of-eight #1 Ethibond, and 0 Vicryl, 2-0 Vicryl,

and staples in the skin. A sterile dressing was applied. The patient

was successfully awakened and returned to the PACU in satisfactory

condition.
