Rotator cuff tear may have significance include os acromiale and acromial spurs. Environmental factors implicated include increasing age, shoulder overuse, smoking, and any medical condition that affects circulation or impairs the inflammatory and healing response, such as diabetes mellitus. Intrinsic factors refer to injury mechanisms that occur within the rotator cuff itself. The principal is a degenerative-microtrauma model, which supposes that age-related tendon damage compounded by chronic microtrauma results in partial tendon tears that then develop into full rotator cuff tears. As a result of repetitive microtrauma in the setting of a degenerative rotator cuff tendon, inflammatory mediators alter the local environment, and
Vaginal cuff Vaginal cuff The vaginal cuff is the upper portion of the vagina that opens up into the peritoneum and is sutured shut after the removal of the cervix and uterus during a hysterectomy. The vaginal cuff is created by suturing together the edges of the surgical site where the cervix was attached to the vagina. This is accomplished by bringing the edges of the vagina together and suturing them together and to the uterosacral ligaments to prevent prolapse. The peritoneum is also sewn into the newly created vaginal cuff. There may be an advantage to using one method of closure
