Preparation of gentamicin-loaded electrospun coating on titanium implants and a study of their properties in vitro.
Implant-related infections are disastrous complications in the clinic, and there are no effective therapies. In this preliminary study, gentamicin-loaded coating on titanium implants was prepared using the electrospinning technique, and some properties of the coating titanium implants were studied. ⋯ The gentamicin-coated titanium implants, which were prepared using an electrospinning technique, present many advantages and may be considered to prevent and treat the implant-related infections.

Position of the popliteal artery in revision total knee arthroplasty.
Injury to the popliteal artery during total knee arthroplasty is a devastating complication. This topic was studied previously prior to primary total knee arthroplasty. This study aims to demonstrate the position of the popliteal artery in patients prior to revision total knee replacement. ⋯ This study has shown that in a revision knee situation, there is no reliable fall back of the popliteal artery in knee flexion; in fact, implant/artery distance may be decreased and caution must be exercised throughout the procedure. It may be worth considering either ultrasound or arteriography in selected cases.

Percutaneous vertebroplasty for pathological vertebral compression fractures secondary to multiple myeloma.
Vertebral compression fractures are common in multiple myeloma. Percutaneous vertebroplasty is used to stabilize vertebral collapse and treat the pain. The major technical drawbacks of percutaneous vertebroplasty are the potential for neural comprise and pulmonary embolism of cement from leakage of polymethylmethacrylate into epidural space and perivertebral veins. We have retrospectively evaluated the safety and complication of percutaneous vertebroplasty in the vertebral compression fractures resulting from multiple myeloma. ⋯ In this study, vertebroplasty significantly improved pain scores and function and, thereby, the quality of life. There were no major procedure-related complications in this study. Direct cytotoxic effect, polymerization and biomechanical microfractures stabilizer of polymethylmethacrylate play multiple roles in pain relief. In multiple myeloma, when pathological spinal compression fractures cause intractable pain and are unresponsive to conservative treatment, vertebroplasty remains the best option for pain relief and is effective in increasing quality of life.

Suture fixation versus cable cerclage of the tuberosities in shoulder arthroplasty-clinical and radiologic results.
The most important individual parameter linked to functional outcome following hemiarthroplasty for fractures of the proximal humerus is anatomical healing of the tuberosities. The aim of our study was to evaluate whether the fixation method influences tuberosity healing and functional outcome. ⋯ In our collective adding an encircling steel cable for the fixation of the tuberosities resulted in higher anatomical healing rates.

Postoperative stability on lateral radiographs in the surgical treatment of pertrochanteric hip fractures.
Fixed-angle sliding hip-screw devices are commonly used to treat pertrochanteric fractures. The controlled impaction between the head and neck fragment and the femoral shaft fragment is crucial. However, the poor quality of fracture reduction can intercept controlled impaction and lead to excessive sliding. We hypothesized that excessive sliding occurs when most of the impaction is placed on the fragile posterior cortex of the fracture site. ⋯ Excessive sliding occurs in surgical treatment for pertrochanteric fractures with posterior displacement of the head and neck fragment. In such cases, we recommend appropriate reduction prior to internal fixation.
