Clinical and anatomical outcomes of isolated coracoclavicular fixation after acromioclavicular joint injury: is it stable enough or is additional horizontal fixation necessary?

Background: Recently, an emphasis has been put on anatomical reduction of acromioclavicular (AC) joint both in vertical and hortizontal planes for management of AC joint injuries due to persisting horizontal instability. Therefore, an additional AC fixation in horizontal plane has been recommended. However, relation between horizontal AC joint instability and clinical outcomes is still controversial.

Multidirectional instability of the shoulder: surgical techniques and clinical outcome.

Multidirectional instability of the shoulder has a complex pathoanatomy. It is characterized by a redundant glenohumeral capsule and increased joint volume. Subtle clinical presentation, unclear trauma history and multifactorial etiology poseses a great challenge for orthopedic surgeons in terms of diagnosis.

Older age and higher body mass index are independent risk factors for tendon healing in small- to medium-sized rotator cuff tears.

Purpose: Many previous research efforts have been made to identify prognostic factors for rotator cuff healing. However, majority of these studies were conducted with heterogeneous cohorts consisted of different tear characteristics. Healing properties of a rotator cuff tear may differ depending on tear characteristics such as tear size or fatty infiltration.
