[Treatment of femoral periprosthetic fracture of Vancouver type B1 and C with bridge combined internal fixation system].

Objective: To evaluate the clinical effect of bridge combined internal fixation system in the treatment of periprosthesis fracture of femur after hip replacement.

Methods: From October 2016 to June 2018, 5 patients of periprosthesis fractures of femur classified type B1 and type C in Vancouver were treated by open reduction and bridging combined with internal fixation, including 2 males and 3 females, with ages of 68, 70, 74, 75, 79 years;type B1 fractures in 4 and type C fractures in 1. Causes of injury:1 case of traffic injury, 4 cases of fall.

Effect of the combination of high-frequency repetitive magnetic stimulation and neurotropin on injured sciatic nerve regeneration in rats.

Repetitive magnetic stimulation is effective for treating posttraumatic neuropathies following spinal or axonal injury. Neurotropin is a potential treatment for nerve injuries like demyelinating diseases. This study sought to observe the effects of high-frequency repetitive magnetic stimulation, neurotropin and their combined use in the treatment of peripheral nerve injury in 32 adult male Sprague-Dawley rats.

Treatment of high-energy tibial shaft fractures with internal fixation and early prophylactic NovaBone grafting.

Objective: To evaluate the safety and efficacy of early NovaBone grafting in accelerating healing of high-energy tibial shaft fractures.

Methods: In a prospective, randomized, controlled study 78 patients with open or closed tibial shaft fractures were treated with reamed interlocking nails, combined with NovaBone grafting. Forty patients were randomly assigned to the experimental group (with NovaBone grafting at fracture site), and 38 to the control group (without NovaBone grafting).
