Arthroscopic repair of HAGL lesions yields good clinical results, but may not allow return to former level of sport.

Purpose: There is a paucity of evidence regarding mid- to long-term clinical outcomes of arthroscopic repair of humeral avulsion of the glenohumeral ligament (HAGL). This study investigated clinical outcomes, return to sport and the frequency of associated shoulder lesions.

Methods: Eighteen patients underwent arthroscopic repair of a HAGL lesion between 2008 and 2015.

Monocortical fixation of the coracoid in the Latarjet procedure is significantly weaker than bicortical fixation.

Purpose: A crucial step of the Latarjet procedure is the fixation of the coracoid process onto the glenoid. Multiple problems associated with the fixation have been described, including lesions of the suprascapular nerve due to prominence of the screw or bicortical drilling. The purpose of the present study was to evaluate whether monocortical fixation, without perforating the posterior glenoid cortex, would provide sufficient graft stability.

Fatty degeneration of the deltoid muscle associated with displaced proximal humerus fractures.

Introduction: The use of reverse shoulder arthroplasty (RSA) has increased dramatically over the last two decades, with many surgeons now indicating RSA for the acute management of displaced proximal humerus fractures (PHF) in the elderly. RSA relies on adequate deltoid muscle function to obtain a good outcome, yet no literature to date exists which discusses preoperative assessment of deltoid structure prior to RSA. The purpose of this study was to assess for preoperative fatty deltoid-degeneration in patients with displaced PHF.

Combined Fluoroscopic and Arthroscopic Detection and Removal of a Foreign Body Lost During Elective Shoulder Arthroscopy: A Case Report.

Introduction: We report a case of a lost metal platelet from a radiofrequency ablation probe (VAPR VUE Radiofrequency System, Cool Pulse 90, DePuy, Synthes, Switzerland) in the shoulder joint during elective arthroscopic cuff repair. To the best of our knowledge, this kind of an incident during elective arthroscopy has not been described in the literature so far. In addition, we present an algorithm on how to deal with such an incident.

Arthroscopic Debridement for Irreparable Rotator Cuff Tears.

Background: Arthroscopic debridement represents a salvage procedure for irreparable rotator cuff tears. It is important to accurately diagnose the patient for irreparable rotator cuff tears. The diagnosis and the therapeutic options must be explained to the patient.

[Posttraumatic nonunions and malunions of the proximal humerus. Possibilities and limitations of corrective osteotomy].

Background: According to the future demographic trends the incidence of proximal humeral fractures and subsequent posttraumatic malunions and nonunions of the proximal humerus are expected to substantially increase.

Objectives: This article reviews the indications, techniques and outcomes of corrective osteotomy for the treatment of posttraumatic nounions and malunions of the proximal humerus.

Methods: A selective literature search was performed and personal surgical experiences are reported.

[First degree open, proximal and distal fractures of the lower arm with scapholunate ligament rupture. Case report of severe extremity trauma].

The combination of proximal and distal radius and ulna fractures with scapholunate ligament injury is extremely rare and this type of injury may potentially only be possible in osteoporotic bone. In this case report this rare injury is discussed, a possible therapy regime is presented and a typical postoperative complication is shown.

FTY720 for treatment of ischemia-reperfusion injury following complete renal ischemia; impact on long-term survival and T-lymphocyte tissue infiltration.

Background: Organ dysfunction due to ischemia-reperfusion (I/R) injury is a common problem in transplant, liver, trauma, and heart surgery. I/R injury is mediated by upregulated expression of endothelial cell surface adhesion molecules and subsequent adhesion and activation of circulating leukocytes. The purpose of this study was to evaluate the effect of an intraoperative administration of FTY720 in an animal model with controlled bilateral warm kidney ischemia compared to steroids or placebo application.

FTY720 application following isolated warm liver ischemia improves long-term survival and organ protection in a mouse model.

Background: Ischemia-reperfusion-Injury (I/RI) is a common complication in transplant-, liver-, and heart surgery. The I/RI is mediated and aggravated by different types of leukocytes such as lymphocytes, monocytes, and neutrophil granulocytes, with consecutive enlargement of the expression of adhesion molecules. This study shows an organ-protective effect of an intraoperative FTY720 administration following warm liver ischemia (Pringle's maneuver).

FTY720 for treatment of ischemia-reperfusion injury following complete renal ischemia in C57/BL6 mice.

Background: Organ dysfunction followed by single-organ or even multiorgan failure due to ischemia-reperfusion injury (I/RI) is a common problem in liver and heart transplantation. Various approaches had been attempted to prevent this I/RI. One is the administration of FTY720, a synthetic structural analogue of sphingosine, which induces T-lymphocyte homing with consecutive lymphopenia.
