Clinical TrialMigration characteristics and early clinical results of a novel-finned press-fit acetabular cup.
Ana Nova® is a novel-finned press-fit acetabular cup which showed superior biomechanical characteristics in an experimental set-up. Using Einzel Bild Röntgen Analyse (EBRA) measurements should offer the opportunity to predict implant survival at an early stage. The purpose of this study was to assess migration and clinical outcome 2 years after total hip replacement by a novel-finned press-fit acetabular cup. ⋯ Adverse migration data in this study might predict aseptic loosening and decreased survival of the implant. According to previous studies, it is possible that this effect occurred because of limited accuracy of the EBRA system. In our opinion, migration analyses may not be recommended as a screening tool in a 2 year follow-up.

We investigated the radiographic parameters that may predict distal radial ulnar joint (DRUJ) instability in surgically treated radial shaft fractures. In our clinical experience, there are no previously reported radiographic parameters that are universally predictive of DRUJ instability following radial shaft fracture. ⋯ In the setting of a radial shaft fracture, ulnar variance greater or less than 2 mm was associated with a greater likelihood of DRUJ incongruence/instability following fracture fixation.

ReviewMetatarsalgia, lesser toe deformities, and associated disorders of the forefoot.
Forefoot pain in the adult often alters mobility and has a negative impact on quality of life. Metatarsalgia describes pain localized to the forefoot. ⋯ In addition to lesser toe and metatarsal abnormality, forefoot pain can be attributed to interdigital neuritis, disorders of the plantar skin, and gastrocsoleus contracture. Treatment of these conditions may include shoe modifications, appliances, therapeutic exercises, and surgical repair.

Comparative StudyA comparison of outcomes after K-wire fixation of distal radius fractures with and without associated ulnar styloid fracture.
A prospective study was carried out to compare outcomes after K-wire fixation of distal radius fractures without and with associated ulnar styloid fracture, but without fixation of the styloid fracture. ⋯ An unrepaired ulnar styloid fracture does not affect the outcome of a distal radius fracture which is fixed by the "augmented" K-wire method.

Sacral fractures are generally seen together with pelvic ring fractures. They can also develop in isolated form rarely. Instability is observed in these fractures in rates reaching 30%. ⋯ Serious spinopelvic instability can be talked of in sacral fractures accompanied by pelvic fractures, particularly when the anterior and posterior integrity of the pelvic ring is interrupted together. An aggressive stabilization and fixation must be performed without delay.
