Two-incision technique for minimally invasive total hip arthroplasty

Recently, there has been considerable interest and debate over the application of minimally invasive surgical approaches to primary total hip arthroplasty. The 2-incision technique employs intermuscular and internervous planes to gain access to the hip joint while minimizing the disruption of muscles and tendons. Through the anterior incision, the femoral neck is osteotomized and the head removed, followed by preparation and cementless reconstruction of the acetabulum. The posterior incision permits femoral preparation and reconstruction with a cementless stem. The potential benefits of this technique include decreased perioperative blood loss and pain, more rapid recovery of hip function and return to normal activity, a reduced length of hospital stay, and cosmetically appealing small scars. Other essential considerations include appropriate patient selection, adherence to surgical principles, and familiarity with specialized instruments and implants.     

Minimalinvasive Versorgung von thorakolumbalen Wirbelfrakturen

Minimally invasive surgery for vertebral fractures means less approach-related morbidity, decreased postoperative pain and rapid mobilization of patients. Such procedures can be performed even in elderly patients. However, along with the many advantages, minimally invasive procedures are technically demanding, require sophisticated tools and there is a learning curve for surgeons. Intraoperative visualization is often possible only radiologically and implants are generally much more expensive. Using the data from some 1,000 vertebral fracture cases treated over the past 3.5 years, we have developed a differentiated treatment concept, depending on the age of the patient and the fracture characteristics, which are presented here. Unstable fractures with involvement of the posterior edge are stabilized from a posterior approach, percutaneously with a fixator. In patients under 60 years, monoaxial screws with inserted rods (top loading) are used with which distraction and restoration of lordosis are also possible. Patients over 60 years are treated percutaneously with a polyaxial sextant system with rods inserted to avoid avulsion of the pedicle screws from the vertebral body. To avoid cutting through the vertebra, the fenestrated screws can be augmented with cement. If a vertebral defect remains after posterior treatment, anterior fusion can also be performed endoscopically with an iliac crest bone graft and an anterior plate if necessary. In older patients, often kyphoplasty is sufficient here. For recent, stable osteoporotic fractures with enhancement of the short time inversion-recovery (STIR) T2 sequence on magnetic resonance imaging and severe pain despite analgesics kyphoplasty is performed. This is possible even in high thoracic fractures to T3 using thinner balloons. In 0.34% (2 out of 564) of cases post-operative neurological deficits were observed after cement extravasation.
