What is a periprosthetic humerus fracture?
In revision procedures, periprosthetic humerus fracture frequently occurs either during implant removal or insertion; the remainder being during reaming or broaching (51,60). Most commonly the greater tuberosity is fractured during stem extraction or exposure of the glenoid.
How long does it take a periprosthetic fracture to heal?
In patients that healed, the average time to medial bridging callus formation was 10.7±6.7 weeks, 11.0±6.6 weeks for anterior fracture line and 13.4±7.5 weeks for the posterior fracture line. both patients that failed to heal underwent revision surgery.
How common is periprosthetic fracture?
Periprosthetic knee fractures performing TKA are rare and the reported incidence, ranging from 0.3% to 3.13%, may be under-estimated (6).
What is a periprosthetic fracture?
Periprosthetic fractures are fractures that occur in association with an orthopaedic implant, most often used for joint arthroplasty or fracture fixation. They are associated with significant morbidity and increased mortality in some cases.
How do they fix a periprosthetic fracture?
In some cases of periprosthetic hip fracture, the implant stem is loose. In these situations, the original implant must be removed from the bone and replaced with a new implant. This procedure is called a joint revision. Revision surgery may require special components.
How do you know which side of the humerus is?
Look for the deep olecranon fossa on the lower (distal) end. Rotate the humerus so that the capitulum and trochlea face YOU. If the capitulum is on the left side of the bone, it is a left humerus. If the capitulum is on the right side, it is a right humerus.
Which 2 muscles have the humerus has an insertion site?
The pectoralis major, teres major, and latissimus dorsi insert at the intertubercular groove of the humerus. They work to adduct and medially, or internally, rotate the humerus. The infraspinatus and teres minor insert on the greater tubercle, and work to laterally, or externally, rotate the humerus.
What causes periprosthetic fracture?
Cause. Periprosthetic femur fractures are most often the result of a fall. These fractures can also be caused by a higher energy force, such as a direct blow to the side of the hip or motor vehicle collision.
What is a periprosthetic fracture of the shoulder?
Shoulder Periprosthetic Fractures are intraoperative or postoperative complications associated with shoulder arthroplasty that can lead to loosening and migration of the prosthesis. Diagnosis can be made with pain radiographs of the shoulder and humerus.
How do you diagnose and treat a dislocated shoulder?
Diagnosis can be made with pain radiographs of the shoulder and humerus. CT scan can help identify loosening of the prosthesis. Treatment involves ORIF or revision shoulder arthroplasty depending on location of the fracture and stability of the prosthesis. Fracture located distal to the tip of the stem.
What are the treatment options for a broken shoulder?
Treatment involves ORIF or revision shoulder arthroplasty depending on location of the fracture and stability of the prosthesis. Fracture located distal to the tip of the stem. Identifying what anatomic landmark can help prevent the risk of iatrogenic radial nerve injury when placing a circumferential proximal humerus cable?
What are the risk factors for periprosthetic humeral shaft fractures?
Poor bone quality, female sex, advanced age, and history of rheumatoid arthritis are the risk factors most commonly associated with periprosthetic fractures. All 4 systems used to describe periprosthetic humeral shaft fractures classify fracture patterns according to the anatomic relation of the fracture to the prosthetic stem.
