The hallux valgus angle of the margo medialis pedis as an alternative to the measurement of the metatarsophalangeal hallux valgus angle.

Background: Currently, the metatarsophalangeal angle (hallux valgus angle) is measured based on radiographic images. However, using X-ray examinations for epidemiological or screening purposes would be unethical, especially in children. For this reason it is discussed to measure the hallux valgus angle of the margo medialis pedis (medial border of the foot) documented on foot outline drawings or foot scans.

Radiographic evaluation for AVN following distal metatarsal Stoffella bunion osteotomy.

Background: Avascular necrosis of the metatarsal head, delayed bone healing and nonunion are complications that may occur after distal first metatarsal osteotomies. Intraoperative damage to the extraosseous blood supply, the location of the osteotomy and postoperative vasospasm have been cited as possible causes of such changes. We evaluated Stoffella's subcapital osteotomies which were performed at our department for the correction of moderate to severe hallux valgus deformities.

Osteointegration and implant position after cementless total knee replacement.

Osteointegration and implant position are regions of interest after cementless total knee replacement. The radiographic and functional status of 101 implants in 101 patients were evaluated 3, 12, and 24 months after implantation. To obtain satisfactory radiographs, a fluoroscopically assisted technique was used.

Positioning device for optimal active kinematic real-time magnetic resonance imaging of the knee joint: a technical note.

OBJECTIVE: A prototype of a positioning device created especially for the diagnostic imaging of the patellofemoral joint was developed in order to achieve reproducible examination conditions. DESIGN: For this purpose a clinical trial on healthy test persons was carried out under real examination conditions. BACKGROUND: A special real-time MRI technique (Local-Look-technique) makes the analysis of active functional motion images possible.
