Long - term survivorship and clinical results of the navigated withdrawn ASR ™.

Introduction: Primary goals of the study were to present the mid - to long - term survivorship and clinical, radiological and metal serological results of the first stem - navigated ASR resurfacing at our clinic. Secondary goals were to determine the influence of stem - navigation on the outcome and risk factors for revision in our cohort.

Methods: From Mai 2006 to Mai 2009 46 ASR resurfacing hip systems have been implanted in 43 patients with a median age of 55 years.

First application of segmental trabecular metal cones in a custom-made revision tumor prosthesis of the knee: A technical note.

Background: Tumor prostheses are established as a standard procedure in tumors of the lower extremities. Septic and aseptic loosening remains the main reason for the failure of tumor prostheses. Due to bone defects, the possibilities of anchoring revision prostheses are limited.

Lower Back Pain with Sciatic Disorder Following L5 Dermatome Caused by Herpes Zoster Infection.

We report the case of a 62-year-old patient with lower back pain radiating into the right leg accompanied by numbness. The pain had an acute onset and was resistant to conservative pain treatment. A magnetic resonance imaging (MRI) scan of the lumbar spine showed no degenerative discovertebral lesions, but a swelling of the nerve root supplying the affected dermatome.

Do residents perform TKAs using computer navigation as accurately as consultants?

The implantation of a total knee arthroplasty (TKA) is a milestone in a resident's surgical training. Studies demonstrate higher loosening rates after TKA by inexperienced surgeons. Alignment outliers should be avoided to achieve a long implant survival.

The effect of computer navigation on blood loss and transfusion rate in TKA.

The blood loss that accompanies total knee arthroplasty (TKA) can be substantial. Many patients need perioperative blood transfusions. To avoid anemia and transfusion-related complications, the amount of blood loss and need for blood transfusions must be reduced.
