Revision total hip replacement with a cemented long femoral component: minimum 9-year follow-up results.
Surgical revision after failed total hip replacement is a technically challenging procedure. The aim of this study was to analyze the long-term results of revision total hip replacement using a cemented long femoral component and identify factors that influence the results. ⋯ The quality of cementation was identified as a significant risk factor for further loosening. Revision total hip replacement using a cemented long femoral component yielded satisfactory long-term results in this series.

Case ReportsThe use of a structural free iliac crest autograft for the treatment of acetabular fractures.
Bone and cartilage deficits in the posterior acetabular wall are severe complications resulting from the unsuccessful management or delayed treatment of acetabular fracture. This potentially disastrous condition cannot be treated reliably with the use of reconstruction plates and screws alone. Therefore, this technical report describes a modified anatomical reconstruction method that uses a structural iliac crest autograft and an acetabular tridimensional memory alloy fixation system (ATMFS) to treat late-stage deficits in the posterior wall of the acetabulum. This paper also describes a clinical study of 22 patients with an average of 6.3 years follow-up to evaluate the clinical outcomes of this method. ⋯ The use of a modified iliac crest grafting and ATMFS fixation, as a biological method to reconstruct the acetabulum anatomically may offer better congruence of the joint surface and may ensure good hip joint stability during early postoperative exercise. The medium to long-term results of this method are encouraging.

Case ReportsA case of supracondylar humerus fracture with vascular impairment. Open it up?
Supracondylar humerus fracture is one of the most frequent fractures in childhood. A serious complication is an injury to the neurovascular structures which could potentially result in severe functional impairment. We are presenting the case of a 3-year-old girl with a supracondylar humerus fracture in our emergency department and highlight the diagnostic and therapeutic steps in managing this situation. ⋯ As concomitant vascular injuries after supracondylar humerus fractures are rare, it can be difficult to discriminate a pink pulseless hand from a patient with essential vascular injury. Our case also demonstrates the need for short-term reevaluation of the clinical status. When in doubt there should be no hesitation to perform open surgery and vascular repair.

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.
