Design and preliminary biomechanical analysis of artificial cervical joint complex.
To design an artificial cervical joint complex (ACJC) prosthesis for non-fusion reconstruction after cervical subtotal corpectomy, and to evaluate the biomechanical stability, preservation of segment movements and influence on adjacent inter-vertebral movements of this prosthesis. ⋯ After cervical subtotal corpectomy, reconstruction with ACJC prosthesis not only obtained instant stability, but also reserved segment motions effectively, without abnormal gain of mobility at adjacent inter-vertebral spaces.

Healing process after rigid plate fixation of humeral shaft fractures revisited.
The purpose of this study was to describe the radiological healing process after open reduction and internal fixation (ORIF) of humeral shaft fractures with plate. ⋯ Both primary and secondary healing processes were observed after rigid plate fixation of OTA 12 A or B humeral shaft fractures. Our study revealed that size of gap, mode of compression, type of fracture could affect the type of healing, and that periosteal callus formation can occur after rigid plate fixation.

Coronal plane fractures of the distal humerus involving the capitellum and trochlea treated with open reduction internal fixation.
Coronal plane fractures of the distal humerus involving the capitellum and trochlea are rare. Treatments have evolved from closed reduction to open reduction and internal fixation (ORIF) to achieve a stable joint that allows early mobilization. ⋯ Level IV case series.

Treatment of large posttraumatic tibial bone defects using the Ilizarov method: a subjective outcome assessment.
The treatment of large posttraumatic tibial bone defects using the Ilizarov method was shown to be successful in several studies. These studies, however, typically focus on the radiological and functional outcome using objective parameters only. The aim of the present study was therefore to assess the objective and subjective outcome of a consecutive series of patients with large posttraumatic tibial bone defects using the Ilizarov method. Additionally, it was our goal to assess the physical and mental stress for the patients and their relatives during the long treatment period and the general health status at final follow-up. ⋯ The Ilizarov method is a safe option for the treatment of large posttraumatic tibial bone defects after failure of internal fixation despite the high complication rate. It is essential to comment this to the patients and their relatives prior to the application of the frame increase their compliance with the long and emotionally draining treatment. The Ilizarov method is worth the effort only in patients, who will presumably comply with this treatment option and all of its drawbacks.

Uncemented third-generation ceramic-on-ceramic total hip arthroplasty using metal acetabular shell with direct taper locking liner.
The ceramic-on-ceramic (CoC)-bearing couple in total hip arthroplasty (THA) was developed to reduce the wear debris and osteolysis. Although the mechanical strength of third-generation ceramic has improved over previous generations, the risk of osteolysis and ceramic fracture is still an important concern. ⋯ Patients, who received third-generation CoC THA had no detectable wear and osteolysis. One ceramic fracture occurred, and the main reason for revision was dislocation.
