The frequency of infectious diseases of the spine and associated spinal cord injury are constantly increasing. Affected are multimorbid and elderly patients, mostly after prolonged medical treatment. An acute spinal cord injury due to infection is an emergency. ⋯ Just as in cases of spondylodiscitis without spinal cord injury inconsistent surgical or insufficient antibiotic treatment worsens the prognosis significantly. If it is possible to remit the infection, the prognosis for recovery of motor and sensory function is better than in cases with traumatic spinal cord injury. In many cases at least partial recovery can be observed.

The term axial spondyloarthritis covers patients with established structural changes visible on x-ray in sacroiliac joints and/or in the spine (classical ankylosing spondylitis) but also patients with non-radiographic axial spondyloarthritis in whom early inflammatory signs of the disease can only be visualized with magnetic resonance imaging (MRI). The MRI technique plays an important role in the diagnosis of this disease and an early diagnosis is normally based on a combination of clinical, laboratory and imaging parameters. Only non-steroidal anti-inflammatory drugs and TNF-α blockers are effective in the treatment of axial spondyloarthritis. Patients with short disease duration and elevated acute phase reactant levels demonstrate best therapy response and, therefore, should be closely followed-up and consistently treated.

The most common joint destructive chronic inflammatory diseases in orthopedic rheumatology are rheumatoid arthritis, psoriatic arthritis and spondyloarthropathy. They usually have a multilocular, characteristic progressive joint destructive course, which must be taken into account when planning surgical treatment. ⋯ The choice of surgical procedure depends on the joint, the surrounding soft tissues and stage of destruction but the increased surgical risk and complications caused by the disease, specific medications and frequent comorbidities also have to be considered. Due to numerous perioperative characteristics close interdisciplinary cooperation especially with internist rheumatologists, anesthetists and physiotherapists is essential for a successful rheumatologic orthopedic therapy.

Case Reports
[Risk factors for failed cleansing following periprosthetic delayed hip prosthesis infection].
Despite extensive cleansing concepts recurrent infections are relatively common especially for infections of hip prostheses. The aim of this retrospective study was to identify factors which hinder cleansing and facilitate recurrence. ⋯ A poorer general physical condition and resistant infectious pathogens are the main risk factors for recurrent infections following prosthesis reimplantation. Therefore, a different treatment concept should be used for polymorbid patients with resistant pathogen infections.

Review
[Antiplatelet therapy after coronary stenting and its importance in total joint arthroplasty].
Coronary stenting is an effective treatment for reopening atherosclerotic occlusions of coronary arteries. Depending on the manifestation of coronary artery disease (stable CAD or acute coronary syndrome) and on the type of implanted stent, dual antiplatelet therapy is recommended for a period of 4 weeks to 12 months. In this period total joint replacement is associated with high blood loss and high perioperative morbidity. ⋯ The surgery should be scheduled after the dual antiplatelet therapy is replaced by lifelong aspirin therapy. On the other hand, if surgery cannot be postponed perioperative bridging of dual antiplatelet therapy can be conducted to minimize bleeding complications with the best possible stent protection. Lifelong therapy with aspirin should not be discontinued in any case.
