Inter- and intraobserver reliability of morphological Mutch classification for greater tuberosity fractures of the proximal humerus: A comparison of x-ray, two-, and three-dimensional CT imaging.

Background: The objective of this study was to investigate inter- and intraobserver reliability of the morphological Mutch classification for greater tuberosity (GT) fragments in consecutive proximal humerus fractures (PHF) regardless of the number of parts according to the Codman classification system for three different imaging modalities (plain radiographs, two-dimensional [2-D] computed tomography [CT], and reformatted, three-dimensional [3-D] CT reconstruction).

Materials And Methods: One hundred thirty-eight consecutive PHF with GT involvement were identified between January 2018 and December 2018 in a supraregional Level 1 trauma center. GT morphology was classified by three blinded observers according to the morphological Mutch classification using the picture archiving and communication software Visage 7.

Nonsensus in the treatment of proximal humerus fractures: uncontrolled, blinded, comparative behavioural analysis between Homo chirurgicus accidentus and Macaca sylvanus.

Objective: To investigate the inter-rater reliability of Barbary macaques compared with an expert group of surgeons for the choice of treatment and predicted outcome of proximal humerus fractures.

Design: Uncontrolled, blinded, comparative behavioural analysis.

Setting: Germany and United States.

[Transcutaneous osseointegrated prosthetic systems after major amputation of the lower extremity : A retrospective 3-year analysis].

Introduction: Transcutaneous osseointegrated prosthetic systems (TOPS) are an established optional procedure for the prosthetic treatment of amputations. Under the term endo-exo-prosthesis (EEP), the endosteal adapted exo-prosthesis (Dr. Grundei®) is currently used as the only standard prosthesis for clinical application in Germany.

Biomechanical Assessment of Three Osteosynthesis Constructs by Periprosthetic Humerus Fractures.

Background: Biomechanical stability assessment of 3 different constructs for proximal fixation of a locking compression plate (LCP) in treating a Worland type C periprosthetic fracture after total shoulder arthroplasty.

Methods: 27 Worland type C fractures after shoulder arthroplasty in synthetic humeri were treated with 14-hole LCP that is proximally fixed using the following: (1) 1 × 1.5 mm cerclage wires and 2x unicortical-locking screws, (2) 3 × 1.

Distal Biceps Tendon Repair Using a Modified Double-Incision Technique: Patient-Reported Outcomes With 10-Year Follow-up.

Background: In the setting of complete distal biceps tendon rupture, surgical repair has become the standard of care to restore optimal elbow function, but the optimal approach and method of tendon fixation are still subjects of debate and have remained controversial for more than half a century.

Purpose: To evaluate patient-reported long-term outcomes after distal biceps tendon repair using a modified double-incision technique.

Study Design: Case series; Level of evidence, 4.

Three-year follow-up of changes of cortical bone thickness after implantation of Endo-Exo-Prosthesis (EEP) for transfemoral amputees.

Introduction: Transcutaneous Osseointegrated Prosthetic Systems (TOPS) offer a good alternative for patients who cannot be satisfactorily rehabilitated by conventional suspension sockets. The Endo-Exo-Prothesis (EEP, ESKA Orthopaedic Handels GmbH®, Deutschland) is the most implanted TOPS in Germany. Previous studies have shown that cortical thickness increases after implantation of TOPS.

Perioperative mortality secondary to a pulmonary embolism during a surgical implantation of the Endo-Exo-Prosthesis: a case report.

We report on a 53-year-old female patient who suffered a perioperative death secondary to a pulmonary embolism (PE) during an implantation of Endo-Exo-Prosthesis. This is a retrospective review of medical case for a patient who had a previous above-the-knee amputation secondary to a failed previous arthroplasty surgery. Our planned surgery was a stage 1 implantation of an Endo-Exo-Prosthesis, and it was performed under general anaesthesia.

[Non-cryoconserving storage strategies for fresh osteochondral allografts].

Background: The clinical outcome of fresh allogeneic osteochondral allografts (OCA) is greatly dependent on the number of viable chondrocytes at the time of implantation. The selection and preparation of a suitable recipient can be very time-consuming and the number of tissue donors is greatly limited; therefore, the preservation of high allograft viability before transplantation is a focal point of current research.

Objective: The objective of this review is to give an overview of established storage strategies for OCA and to serve as a decision-making aid for German clinics in the choice of a suitable storage strategy.

Lactated Ringer-based storage solutions are equally well suited for the storage of fresh osteochondral allografts as cell culture medium-based storage solutions.

Background: Due to the rising interest in Europe to treat large cartilage defects with osteochondrale allografts, research aims to find a suitable solution for long-term storage of osteochondral allografts. This is further encouraged by the fact that legal restrictions currently limit the use of the ingredients from animal or human sources that are being used in other regions of the world (e.g.

Impact of Resident Involvement in Surgery (IRIS-NSQIP): Looking at the Bigger Picture Based on the American College of Surgeons-NSQIP Database.

Background: Surgical residency training aims to prepare the surgical resident to become an independent practitioner of surgery. Because surgical residency training remains the sole educational channel to prepare surgeons for independent practice, our study aimed to explore the effect of resident involvement in surgery across a broad spectrum of surgical specialties to answer questions patients, surgeons, and surgical residency program directors may have concerning the effect of having residents participate in performing surgical operations.

Study Design: This analysis used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database to establish whether patients having operations involving residents were at a risk of postoperative mortality or morbidity similar to patients having operations performed by attending surgeons alone, across a wide array of surgical procedures.

Iron chelation therapy in transfusion-dependent thalassemia patients: current strategies and future directions.

Transfusional iron overload is a major target in the care of patients with transfusion-dependent thalassemia (TDT) and other refractory anemias. Iron accumulates in the liver, heart, and endocrine organs leading to a wide array of complications. In this review, we summarize the characteristics of the approved iron chelators, deferoxamine, deferiprone, and deferasirox, and the evidence behind the use of each, as monotherapy or as part of combination therapy.
