Introduction: Trimalleolar fractures are difficult to treat and malreduction can lead to functional impairment. Involvement of the posterior malleolus has a poor predictive value. Current computed-tomography (CT)-based fracture classifications led to an increase in fixation of the posterior malleolus.

Background: The proximal humerus fracture is a common injury, but the optimal management is much debated. The decision for operative or nonoperative treatment is strongly influenced by patient specific factors, regional and cultural differences and the preference of the patient and treating surgeon. The aim of this study is to compare operative and nonoperative treatment of proximal humerus fractures for those patients for whom there is disagreement about optimal management.

Purpose: Proximal humeral fracture-dislocations (PHFD) are challenging to treat. In older patients, usually arthroplasty is performed. In younger patients, osteosynthesis is chosen.

Purpose: In recent years a trend from conservative to operative treatment of displaced scapula fractures has evolved. The aim of this study was to assess surgical and patient-based radiological and functional outcome after open reduction and internal fixation (ORIF) of displaced scapula fractures following predefined operative indications.

Methods: We retrospectively analyzed data of a consecutive series of patients with displaced scapula fractures following operative fixation at our institution between 06/2010 and 02/2020.

Introduction: Combined limb-sparing surgery and radiation therapy are considered the standard of care for higher grade soft tissue sarcomas (STS) of the extremities. The risk of post-radiation fracture after this treatment modality is well known, but still underestimated, and can end in serious long-term secondary problems years later.

Presentation Of Case: We reviewed the records of three patients with pathological femur fractures years after wide local excision of an STS of the proximal lower extremity.

Purpose: Midshaft clavicle fractures represent about 4% of all fractures in the emergency department. Non-operative treatment of displaced midshaft clavicle fractures (DMCF) can result in a relatively high non-union rate. Several operative techniques, including intramedullary fixation (IMF) using elastic stable intramedullary nailing (ESIN), have therefore been established.

Background: There is no consensus on the optimal operative technique for humeral shaft fractures. This meta-analysis aims to compare minimal-invasive plate osteosynthesis (MIPO) with open reduction internal fixation (ORIF) for humeral shaft fractures regarding non-union, re-intervention, radial nerve palsy, time to union, operation duration and functional outcomes.

Methods: PubMed/Medline/Embase/CENTRAL/CINAHL were searched for both randomized clinical trials (RCT) and observational studies comparing MIPO with ORIF for humeral shaft fractures.

Background: Proximal humeral fracture-dislocations (PHFD) are a special entity in proximal humeral fracture treatment. The aim of this study is to present our minimally invasive plate osteosynthesis (MIPO) technique through an anterolateral deltoid split approach. In addition, we performed a retrospective cohort study analyzing the patient reported functional outcome and complications.

Purpose: Intraoperative precise visualization of fractures and assessment of the quality of reduction is essential in orthopedic trauma surgery. Fluoroscopic skills will lead to an increased detection rate of minimal abnormalities needing revision intraoperatively. The definition of fluoroscopic skills and the interpretation of acceptable "minimal abnormalities" remains somehow unclear.

Purpose: Sternal fractures are rare injuries and mostly treated non-operatively. In selected cases, internal fixation becomes necessary. No standard operative approach has been determined yet among experts.

Background: For decades, clavicle fractures have been treated conservatively. In the last 20 years, however, non-union rates after conservative treatment appear higher than previously reported and more evidence regarding operative treatment has become available. This has led to a paradigm shift towards an increase in operative treatment.

The purpose of this study was to describe our experience with a possible solution for implant- related irritation after intramedullary nailing of displaced midshaft clavicle fractures: the end cap. Ten patients with a displaced midshaft clavicle fracture were treated with intramedullary nailing and an end cap in 2013. Patients were followed in the outpatient clinic until fracture union.

Purpose: Different fixation methods are used for treatment of unstable lateral clavicle fractures (LCF). Definitive consensus and guidelines for the surgical fixation of LCF have not been established. The aim of this study was to compare patient-reported functional outcome after open reduction and internal fixation with the clavicle hook plate (CHP) and the superior clavicle plate with lateral extension (SCPLE).

There is an increasing incidence of proximal humerus fractures. Patients with proximal humerus fractures have traditionally been treated conservatively. During the past decades, however, various new osteosynthetic and prosthetic implants have been developed for the shoulder and surgical treatment of proximal humerus fractures has increased.

Objectives: Medial clavicle fractures are rare injuries and historically treated non-operatively. Displaced medial clavicle fractures, however, have a higher incidence of delayed- or non-union compared to non- displaced medial clavicle fractures and might benefit from operative treatment. We describe below a new technique for treating intra-articular fractures or extra-articular fractures with a small medial fragment using special locking plates and present the results of our operatively treated patients.

Purpose: The purpose of this study was to evaluate the frequency of changes in treatment plan due to standardized postoperative radiographs. A secondary aim was to compare our results with a national benchmark.

Methods: This is a single-center retrospective case series of 167 consecutive patients, operated with open reduction and internal fixation (ORIF) for distal radius or ankle fractures in 2014.

Background: There is no consensus on the choice of treatment for displaced proximal humeral fractures in older patients (aged > 65 years). The aims of this systematic review and meta-analysis were (1) to compare operative with nonoperative management of displaced proximal humeral fractures and (2) to compare effect estimates obtained from randomized controlled trials (RCTs) and observational studies.

Methods: The databases of MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) were searched on September 5, 2017, for studies comparing operative versus nonoperative treatment of proximal humeral fractures; both RCTs and observational studies were included.

Septic arthritis of the pubic symphysis is a potentially severe disease. Athletes are at risk of this form of spontaneous arthritis, as inflammation of the pubic bone due to muscular stress is relatively common. Oedema due to inflammation might predispose to infection through bacteraemia or local bacterial translocation.

Objective: Lower leg fractures of the tibia with or without fracture of the fibula are very common. Proximal tibiofibular joint (PTFJ) dislocation is a very rare injury that can occur together with a tibia shaft fracture. As there is only scarce literature about this injury available, we would like to present our experience with the treatment of this entity.

We report a rare case of recurrent abscess formation, including being at a retroperitoneal site, due to a lost and migrating appendicolith. Over a four-year period and following an episode of perforated appendicitis, an otherwise healthy young man underwent two operations for abscess formation with eventual stone removal. Appendicoliths can pose a challenge during the diagnostic and therapeutic journey, and adequate attempts at removal need to be made to prevent avoidable complications.

Frostbite injuries rarely occur in healthy Dutch persons. However, as the number of people engaging in winter and outdoor activities and travelling to high altitudes increases, the risk of frostbite also increases. Frostbite is a cold-induced injury which results from two processes: freezing and microvascular occlusion.

Introduction: The integral classification of injuries (ICI), by Zwipp et al. has been developed as a classification system for injuries of the bones, joints, cartilage and ligaments of the foot. It follows the principles of the comprehensive classification of fractures by Müller et al.
