Event Description

This report is being filed after the review of the following journal article: zhao, j. Et al (2018), intercalary prosthetic reconstruction for pathologic diaphyseal humeral fractures due to metastatic tumors: outcomes and improvements, journal of shoulder and elbow surgery, vol. 27(11), pages 2013-2020 ((b)(6)). The purpose of this retrospective case-control study is to evaluate the outcomes and complications of intercalary humeral prosthetic reconstruction for pathologic diaphyseal fractures caused by metastatic lesions. Between 2011 and september 2017, a total of 9 patients (4 male and 5 female) with a mean age of 62. 9±11. 1 years (range, 50-82 years) underwent intercalary prosthetic reconstruction for pathologic diaphyseal humeral fractures secondary to metastatic diseases. Procedures were intercalary prosthetic reconstruction in 4 patients (group a) and an implanted intercalary prosthesis with a plate in 5 patients (group b). For the proximal, midshaft, or distal diaphyseal site of pathologic humeral fractures, we added a philos plate (depuy (b)(4) usa), a straight plate, or a condylar plate, respectively all patients had postoperative radiograph evaluation by the same surgeon until the latest examination included in this study or earlier death. Outpatient follow-up was performed monthly for 3 months, followed by interval of 2 or 3 months for the remaining follow-up. Follow-up was 11. 5±10. 1 months for group a and 6. 2±4. 4 months for group b. The following complications were reported as follow under group a: (non-synthes). 4 (all) patients had died. A (b)(6) female had aseptic loosening but was able to achieved acceptable functional outcome due to preservation of adjacent joints. A (b)(6) male had radial nerve injury but was able to return to normal within 3 months after surgery. An (b)(6) did not survive for 3 months due to sudden complications from heart disease. The following complications were reported as follow under group b: (with plates). 3 patients had died. A (b)(6) male with an additional plate for pathologic fracture of midshaft of left humerus had formation of a bone bridge linking the stem and the proximal fragment encasing the distal implant with heterotopic bone. This report is for an unknown synthes proximal humeral internal locking system (philos) plate. This is report 1 of 1 for (b)(4). A copy of the literature article is being submitted with this medwatch.
