Management of Achilles Tendon Rupture Complications.

The management of Achilles tendon rupture complications has always been a challenge. Rerupture, infection, wound problems, suture reaction, weakness as a result of Achilles tendon lengthening, sural nerve injury, and thrombosis are the most common complications in patients who undergo treatment for Achilles tendon rupture. Given the increasing incidence of Achilles tendon rupture, orthopaedic surgeons must understand the basic principles for the management of Achilles tendon rupture and the appropriate techniques to help reduce the rate of complications.

Retraction Note: Long noncoding RNA ANRIL is activated by hypoxia-inducible factor-1α and promotes osteosarcoma cell invasion and suppresses cell apoptosis upon hypoxia.

Long noncoding RNA ANRIL is activated by hypoxia-inducible factor-1α and promotes osteosarcoma cell invasion and suppresses cell apoptosis upon hypoxia.

Background: Osteosarcoma is the most common malignancy of bone. Intratumoral hypoxia occurs in many solid tumors, where it is associated with the development of aggressive phenotype. ANRIL has been shown to be a long noncoding RNA that facilitates the progression of a number of malignancies.

Regression analysis of controllable factors of surgical incision complications in closed calcaneal fractures.

Background: In surgeries of closed calcaneal fractures, the lateral L-shaped incision is usually adopted. Undesirable post-operative healing of the incision is a common complication. In this retrospective study, controllable risk factors of incision complications after closed calcaneal fracture surgery through a lateral L-shaped incision are discussed and the effectiveness of clinical intervention is assessed.

Preparation of laponite bioceramics for potential bone tissue engineering applications.

We report a facile approach to preparing laponite (LAP) bioceramics via sintering LAP powder compacts for bone tissue engineering applications. The sintering behavior and mechanical properties of LAP compacts under different temperatures, heating rates, and soaking times were investigated. We show that LAP bioceramic with a smooth and porous surface can be formed at 800°C with a heating rate of 5°C/h for 6 h under air.

Restoration of horizontal stability in complete acromioclavicular joint separations: surgical technique and preliminary results.

Background: Our purpose was to investigate the clinical efficacy of arthroscope-assisted acromioclavicular ligament reconstruction in combination with double endobutton coracoclavicular ligament reconstruction for the treatment of complete acromioclavicular joint dislocation.

Methods: During the period from February 2010 to October 2012, ten patients with Rockwood types IV and V acromioclavicular joint dislocation were hospitalized and nine were treated with acromioclavicular ligament reconstruction combined with double endobutton of coracoclavicular ligament reconstruction. The improvement in shoulder functions was assessed using a Constant score and visual analog scale (VAS) system.
