Thermal injury to the radial nerve caused by cement leakage is a rare complication after revision elbow arthroplasty. Several reports have described nerve palsy caused by cement leakage after hip arthroplasty. However, little information is available regarding whether radial nerve injury due to cement leakage after humeral stem revision will recover. In a recent study, radial nerve palsy occurred in 2 of 7 patients who had thermal injury from leaked cement during humeral component revisions. These patients did not regain function of the radial nerve after observation. We present a case of functional recovery from a radial nerve palsy caused by cement leakage after immediate nerve decompression in revision elbow arthroplasty[Fig. 1.2].
Purpose:. Interposition arthroplasty is a salvage procedure for patients with severe osteoarthritis of the elbow where conservative treatment failed. It is mostly performed in younger patients where total joint replacement is contraindicated and an arthrodesis is unattractive. Although one of the oldest reconstructive options for elbow arthritis, the procedure is not without complications. There are only a few case series described in the literature. The purpose of our study is to review our cases and report their outcome. Method. We retrospectively reviewed 18 consecutive cases of interposition arthroplasty between 2001 and 2010. 2 cases were excluded due to incomplete records. The mean patient age was 41.3 (19.4–58.6) years at time of surgery. The primary diagnosis was post-traumatic osteoarthritis in 11 cases and inflammatory osteoarthritis in 5 cases. The mean follow up was 4.7 (0.4–10) years. Pre- and post-operative pain and function was evaluated using the Visual Analogue Scale (VAS) and Mayo Elbow Performance Score (MEPS). The complications and the number of re-operations and revisions were recorded. Summary of results:. In 12 (75%) cases at least one revision operation was performed, because of sepsis, ulnar nerve symptoms, instability and unsatisfactory clinical results. Sepsis rate was 25%. In 7 cases there was an unsatisfactory clinical result (i.e. ongoing pain and poor function), resulting in
Background. The procedures of total elbow and shoulder replacements increased 6% to 13% annually from 1993 to 2007 with revision-related burden increasing from 4.5% to 7%. The revisions of the shoulder and elbow prostheses due to aseptic loosening, periprosthetic fractures, infections have led to the use of standard or custom-made implants due to significant bone loss. This study reports our experience in the management of complicated primary and revisions of total shoulder and elbow replacements with significant humeral bone loss and in metabolic diseases of the elbow and shoulder treated with bone resection using The Mosaic Humeral Replacement System. Patients and Materials. A total of 20 patients underwent total elbow or shoulder arthroplasty using the Mosaic Humeral Replacement System (Biomet, UK). The Mosaic system was used in 8 shoulder arthroplasties (Group A) and in 12 elbow arthroplasties (Group B). The underlying pathologis in Group A included 2 malunited proximal humerus fracture, 1 humeral osteomyelitis, 1 shoulder chondrosarcoma, 1 aggressive Gigantic Cell Tumor with prosthetic fracture, 2 metastatic lytic lesion, and 1 failed fixation of non-union proximal humerus. Figure 1 shows Mosaic implant after complex fracture of proximal humerus. Reasons for Mosaic arthroplasty in Group B included 3 humeral component revisions due to periprosthetic fracture, 1 prosthesis breaking-up with fractures, 1 revision of loose Souter Strathclyde prosthesis, 1 loose prosthesis due to infection, 1 highly comminuted elbow fracture, 1 aseptic loosening of humeral component of
