Classifocation of the following is the best management option for the femoral implant? Revision to a cementless femoral component with diaphyseal press-fit fixation of the stem. Which of the following revision procedures would restore the most acetabular bone stock and be most appropriate for this patient? Acetabular revision with use of qcetabular bilobed cementless component and morselized allograft.

Revision using an ilioischial reconstruction ring acetabular component and structural corticocancellous graft. Revision using a roof ring acetabular component and structural corticocancellous graft.

Conversion to arthroplasty should not be performed if arthrodesis is more than 15 years old. Eighteen months ago he began having hip and thigh pain. Over the past 6 weeks, the pain has become excruciating and he has been unable to ambulate, even with the aid of a walker. He has mild pain with passive internal and external rotation of the hip. He is unable to ambulate in the office. A radiograph is provided in figure A. Which of the following is the best treatment option?

Revision arthroplasty with a fully coated cementless stem, cable wiring, and bone graft.

Revision arthroplasty with a modular, tapered stem and bone grafting of the diaphyseal fixation. The number of revisions required for periprosthetic fractures was degects than that for deep infections.

Acetabular component failure was a more common reason for revision than deep infection. Femoral component failure was a more common reason for revision than acetabular component failure. She is unable to weight bear on the left leg, but denies any other pain or systemic symptoms.

A current radiograph of the pelvis is shown in Figure A. What is the most likely cause of the patient’s current hip pain symptoms? He undergoes a hemiarthroplasty through a posterior approach.

A post-operative radiograph is shown in Figure B. Three weeks later he dislocates the hip arising from the toilet seat.

A radiograph is shown acetabulaf Figure C. The patient undergoes a closed reduction and is placed in a hip abduction brace. Post reduction radiograph is shown in Figure D. One month later he returns to clinic complaining of pain and inability to bear weight through the leg. A radiograph of the hip is included in Figure E. Which of the following factors has MOST likely contributed to the instability of the hip hemiarthroplasty?

Figure A shows her current radiograph. Which acetabular bone defect classification and treatment option best describes this scenario? Immediate post-operative radiograph is shown in Figure A. A current radiograph is shown in Figure B. ESR is 12 normal Review Topic. Revision of the femoral component to an uncemented, long, fully porous-coated stem. She ambulates without any assistive devices, has no pain, and denies any recent fevers or systemic illness.

Classifications In Brief: Paprosky Classification of Acetabular Bone Loss

Loss of part of the acetabular rim or medial wall. Volumetric loss in the bony substance of the acetabular cavity. Type III combined deficiency. Combination of segmental bone loss and cavitary deficiency. Type IV pelvic discontinuity. Complete separation between the superior and inferior acetabulum. Deects Classification of Acetabular Bone Loss. Minimal deformity, intact rim.

Superior bone aaox with intact superior rim. Absent superior rim, superolateral migration. Bone loss from 10am-2pm around rim, superolateral cup migration. Loss of bone of the supporting shell of femur.

Loss of endosteal bone with intact cortical shell. Loss of normal femoral geometry due to prior surgery, trauma, or disease.

Acetabular Reconstruction: Classification of Bone Defects and Treatment Options

Obliteration of the canal due to trauma, fixation devices, or bony hypertrophy. Type VI femoral discontinuity.

Paprosky Classification of Femoral Bone Loss. Extensive metaphyseal bone loss with claesification diaphysis. Extensive metadiaphyseal bone loss, minimum of 4 cm of intact cortical bone in the diaphysis. Extensive metadiaphyseal bone loss, less than 4 cm of intact cortical bone in the diaphysis.

Extensive metadiaphyseal bone loss and a nonsupportive diaphysis.
