ShoulderComplications and survival after surgical treatment of 214 metastatic lesions of the humerus
Section snippets
Data source
The Scandinavian Sarcoma Group Skeletal Metastasis Register was initiated in 1999 as a multicenter database for quality control and scientific research. Data are prospectively collected in a blinded manner on patients surgically treated for pathologic fractures in the long bones and pelvis in the orthopedic tumor centers.10
Patients
This study includes a consecutive series of patients surgically treated for pathologic humeral fractures from 1999 to 2006 were included. Only patients who had their primary
Failures and complications
The surgical procedure in 20 of the 214 cases ended in a failure of the reconstruction, corresponding to a failure rate of 9% (Table II). The median follow-up time from fracture surgery until failure was 8 months (range, 0-97 months). The cumulative survival after surgery was 40% (95% CI 34-47) at 1 year, 21% (95% CI 15-26) at 2 years, and 16% (95% CI 12-19) at 3 years (Fig. 2).
Of the 20 failures, 7 were attributable to nonunion, 4 to deep infection, 4 to stress fracture, 3 to poor initial
Surgical procedures
In 48% of the patients, the operative strategy was stabilization without local tumor treatment. This method was mainly used with intramedullary nails. Stabilization with intralesional curettage and augmentation with bone cement (45%) was most commonly used in combination with internal fixation or prosthetic reconstruction, or both.
Hemiarthroplasty was most commonly performed for proximal humeral fractures. Diaphyseal fractures were mainly treated with intramedullary nails and distal humeral
Discussion
Our main findings were that patients undergoing surgery for skeletal metastases of the humerus had a 1-year survival rate of 40%. As expected, the Cox regression analysis showed that a primary tumor in the lung, a poor and moderate Karnofsky score, multiple skeletal metastases, and the presence of visceral metastases were factors associated with a poor prognosis after surgery (Table III). The failure rate of the surgical reconstructions was 9%. Prostate cancer and distal humeral fractures
Conclusion
A cemented hemiprosthesis is our method of choice in proximal humeral fractures, and the interlocked intramedullary nail is preferred in treating destruction of the diaphysis. Pathologic fractures in the distal humerus are uncommon and associated with a very high reoperation rate.
