The rare case of a 63-year-old male diagnosed with pneumatosis cystoides intestinalis coli is presented and discussed. The patient was found to have an unsymptomatic pneumoperitoneum on plain chest x-ray. The results of a contrast enema, computed tomography scan, and laparoscopy are presented. The patient had an uneventful hospital course without any specific therapy. Causes and possible therapeutic options are discussed.
Resurfacing arthroplasty is regarded as an attractive method, especially for the young patient who needs a hip replacement. However, the high expectations regarding this new technique in THR must first be met. Earlier experiences with similar forms of surface replacement have led to high revision rates with early aseptic wear induced component loosening and neck fractures. Technical progresses in production techniques for metal-on-metal articulations with minimized wear have enabled the introduction of new surface replacements for the hip joint. Long-term results of these resurfacing arthroplasties are still due. Femoral neck fractures and femoro-acetabular impingement are possible early complications which require revision. The implantation of these systems requires a high degree of operative skill and experience on the part of the surgeon. Approach dependent trauma to the musculature and endangering of the blood supply to the femoral head is balanced with the positive effect of the preservation of femoral bone stock and better options in case of revision. Whether the younger patient with a higher activity profile and an increased chance of implant loosening actually profits from the resurfacing arthroplasty will be determined in the future.
Soft tissue defects after knee arthroplasty are a severe problem, which can even result in a loss of the prosthesis or the limb. Well-planned strategies are necessary for sufficient soft tissue reconstruction, resulting in optimal functional and aesthetic results. This report provides information on the classification of the tissue defects and the appropriate options for surgical reconstruction. Besides the basic therapy principles of immobilisation, débridement, planned lavages and antibiotic therapy, defect-dependent surgical techniques of reconstructive surgery are implemented. These include skin transplantation, local fasciocutaneous flaps, local pedicled muscle flaps and free flaps. For best results, interdisciplinary treatment by orthopaedic surgeons, plastic surgeons, microbiologists and physiotherapists is mandatory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
