Prolonged surgical site infections after spinal fusion surgery may lead to exposure of the implant due to the formation of extensive tissue defects and endanger the clinical outcome. ⋯ The keystone perforator flap offers a stable coverage for soft tissue defects and supports infection control after spinal fusion.

With rising numbers of revisions of total arthroplasty procedures of the lower extremities, the annual number of cases of implant-associated infection are also increasing. The conventional two-stage replacement strategy often leads to increased morbidity and mortality of patients; however, in the literature a one-stage exchange procedure shows equally good results if the indications are strictly defined. ⋯ Despite existing controversies in the literature, this treatment approach seems to demonstrate a reduced hospitalization, reduced costs and improved patient satisfaction with the same re-revision rate. This review article explains the strategic approach to chronic infections of endoprostheses of the lower extremities based on clinical examples and a review of the current literature.

Intramedullary nailing is the treatment of choice for a large number of fractures requiring surgery. In cases of fracture-related infections (FRI) the treatment of nail infections requires special attention due to the closed situation of the osteosynthesis material in the intramedullary canal. This article gives an overview of the general principles and diagnostic criteria for FRI after nail fixation and discusses the treatment recommendations based on three case examples. ⋯ If a chronic infection with soft tissue and bone defects develops after intramedullary nailing, a two-stage procedure analogous to the treatment of osteomyelitis should be considered. In this case a multidisciplinary team approach with specialists in plastic surgery, microbiology and infectious diseases is necessary. The use of local antibiotics and antimicrobial-coated implants is deemed to be advantageous.

Spondylodiscitis and postoperative wound infections are the most frequent infectious diseases of the thoracic and lumbar spine. Every spinal surgeon will come into contact with such patients during his or her career. Knowledge particularly of the diagnostics, conservative and surgical treatment as well as microbiological considerations of antibiotic treatment are therefore of particular importance and are explained in this article.

The triceps brachii muscle is the main extender of the elbow joint. Triceps tendon rupture or tearing presents a rare injury pattern in general. Distal tendon ruptures occur most commonly in the area of the insertion of the olecranon. ⋯ However, the most frequent trauma mechanism is a direct fall onto the extended forearm or a blow to the elbow. Beside clinical examination and sonography, magnetic resonance imaging is the diagnostic gold standard. The treatment of triceps tendon injuries includes conservative as well as operative approaches, whereby the indications for surgical treatment must be generously considered depending on the patient's age, functional demands of the patient, involvement of the dominant extremity as well as on the extent of the tendon rupture.
