Selective nitric oxide synthase inhibitor promotes bone healing.

Background: Nitric oxide (NO) has many functions in wound healing and bone metabolism. This study sought to assess the local effect of aminoguanidine (AG), a selective inducible NO synthase (iNOS) inhibitor, on the rate of bone healing.

Materials And Methods: This experimental interventional study was conducted on 36 rats, which were randomly divided into three groups of control, placebo, and AG.

Comparison of Bristow procedure and Bankart arthroscopic method as the treatment of recurrent shoulder instability.

Background: Anterior shoulder dislocation is the most common major joint dislocation. In patients with recurrent shoulder dislocation, surgical intervention is necessary. In this study, two methods of treatment, Bankart arthroscopic method and open Bristow procedure, were compared.
