Targeting osteomyelitis with complete [99mTc]besilesomab and fragmented [99mTc]sulesomab antibodies: kinetic evaluations.

Background: The aim of this retrospective study was to compare the targeting of "pure" osteomyelitis (i.e., without surrounding soft tissue infection) by directly 99mTc-labelled complete immunoglobulin G (IgG) monoclonal antibody (MAb) ([99mTc]besilesomab) and by directly 99mTc-labelled fragment antigen-binding (FAb) MAb ([99mTc]sulesomab) in relation to their kinetic fate.

Dislocation after total hip arthroplasty: risk factors and treatment options.

Objective: The aim of this study was to analyze the setting for dislocations and redislocations after primary and revision total hip arthroplasty (THA), identify risk factors and optimize treatment.

Methods: This study included 56 patients with a dislocated hip following THA (n=5,205) between 1984 and 2005 and a matched control group (n=55). Hospital charts and radiographs of all patients in both groups were analyzed.

Influence of surgical experience on accuracy of acetabular cup positioning in total hip arthroplasty.

Acetabular cup positioning with respect to inclination and anteversion is important in total hip arthroplasty. Positioning affects wear, range of motion, dislocation, and aseptic loosening and is essential for the prognosis after surgery. In this study, we sought to determine the accuracy of surgeons' cup positioning and to test for any differences in accuracy among surgeons with different levels of surgical experience.

Mesenchymal stromal cells: a novel treatment option for steroid-induced avascular osteonecrosis.

Mesenchymal stromal cells are multipotent cells capable of tissue repair and immune modulation. They are primarily found in bone marrow, but are also present in other tissues of mesenchymal origin, such as fatty tissue, muscle, tendons, etc. MSC can easily be obtained by bone marrow aspiration, showing a rapid expansion in vitro.

Talonavicular arthrodesis or triple arthrodesis: peak pressure in the adjacent joints measured in 8 cadaver specimens.

Background: Talonavicular arthrodesis is a differential indication for triple arthrodesis. Differences regarding intraarticular pressure loads on the adjacent joints have not been investigated to date, but they are of clinical relevance when considering long-term joint degeneration.

Methods: We used a dynamic foot model to measure intraarticular peak pressures with electronic sensors in 8 anatomical specimens in different areas of the ankle joint and in the naviculocuneiform joint.

Kirschner wire transfixation of the femoral head in slipped capital femoral epiphysis in children.

Objective: To stabilize the unstable capital femoral epiphysis to stop further slippage. To prevent imminent epiphyseal dislocation with subsequent articulation disorders of the hip joint and joint degeneration. To prevent additional growth disorders of the proximal femur.

Long-term results after metatarsal head resection in the treatment of rheumatoid arthritis.

Background: In this retrospective study, both the patients' and surgeons' satisfaction with resection of the first through fifth metatarsal heads for long-standing rheumatoid forefoot deformity was evaluated.

Methods: Thirty-four patients (56 feet) had first through fifth metatarsal head resection. After a mean time of 5.

Measuring anatomical acetabular cup orientation with a new X-ray technique.

Proper alignment of the acetabular cup component is one of the most important requisites for a successful long-term outcome in total hip replacement. However, measurement and indication of cup orientation in an anatomical pelvic reference system is very difficult. We propose a new C-arm-based X-ray technique for determining the values for inclination and anteversion of the acetabular cup component.

The Adaptiva custom-made stem--our reasons for not using it anymore.

The Adaptiva custom-made stem is a hip stem anchored by fit and fill press-fit into the proximal femur and manufacture is based on computed tomography (CT) scanning. Its concept was developed for primary and revision hip arthroplasty in younger patients in our clinic. We present the advantages and the disadvantages of the system.

Pelvic tilt makes acetabular cup navigation inaccurate.

Background: Modern navigation techniques allow precise positioning of the acetabular cup relative to the anterior pelvic plane. Variations in pelvic tilt will affect the resulting spatial orientation of the cup.

Methods: We measured pelvic tilt in 30 volunteers with an inclinometer combined with an ultrasonographic position measurement system.
