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.

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.

Percutaneous cerclage wiring and minimally invasive plate osteosynthesis (MIPO): a percutaneous reduction technique in the treatment of Vancouver type B1 periprosthetic femoral shaft fractures.
Periprosthetic femoral fractures (PPFs) associated at or near a well-fixed femoral prostheses (Vancouver type-B1) present a clinical challenge due to the quality of the bone stock and instability of the fracture. ⋯ Percutaneous reduction of spiral, oblique or wedge-type B1 PPFs with percutaneous cerclage wiring combined with minimally invasive locking plate osteosynthesis provided satisfactory reduction, adequate stability and healing in nine patients. Our early results suggest that this reduction technique and fixation may be a useful solution for this growing challenge in orthopaedics. The authors caution that this technique must be done carefully to avoid serious complications, e.g., vascular injury.

Review Case ReportsA novel method of image-based navigation in fracture surgery.
The treatment of three- and four-part fractures of the humeral head is still controversially discussed. Some advocate primary arthroplasty while the results of primary fixation seem to be superior if no necrosis of the humeral head develops. Today navigation is used in orthopaedic surgery mainly for interventions on the spine, the pelvis and arthroplasty. ⋯ In conclusion, the described technique allows an accurate fixation of the humeral head fracture as the guidance system (Surgix) ensures the "first try first hit" screw positioning. The new system was integrated in the workflow and supports the surgeon as an aiming device. The role of navigation system in enhancing minimally invasive surgery of the shoulder should be further explored.

ReviewPrimary clavicle tumors and tumorous lesions: a review of 206 cases in East Asia.
The aim of this study is to systematically review the published literature from East Asia on the clinical, pathological, and epidemiological characteristics of primary clavicle tumor and tumorous lesions. ⋯ Clavicle tumors and tumorous lesions in East Asia had an inclined occurrence in respect to age and gender. The most common tumors were eosinophilic granuloma and tumors derived from the bone marrow hematopoietic system. Age of onset was found to be a risk factor for malignancy. These characteristics may be related to the special tissue structures and mode of development in the clavicle as well as to the genetic traits of the typical Mongoloids in East Asia.
