Background Historically, anatomical total shoulder arthroplasty (ATSA) has been the standard intervention for primary osteoarthritis in patients with an intact rotator cuff. However, there is an increasing trend towards utilizing reverse total shoulder arthroplasty (RTSA) as an alternative in specific cases. The aim of this study is to investigate...

Background While anatomic total shoulder arthroplasty (aTSA) is a well-established procedure for the treatment of end-stage centered glenohumeral arthritis, only few studies have reported the long-term outcomes of modern implants. The purpose of this study was to assess the long-term clinical, radiographic, and patient-reported outcomes after aTSA...

Purpose The aim of this study is to investigate the influence of patient‐specific factors, including age, lifestyle considerations as well as the extent of injury according to the Rockwood classification (RW), on the surgeon's decision‐making in the choice between operative and nonoperative treatment for acute, high‐grade acromioclavicular (AC) joi...

Background To assess the results after elbow arthroplasty it is essential to gather patient-reported outcome measures (PROMs). However, the acquisition of PROMs poses a challenge because of potential low literacy, lengthiness and diversity of questionnaires, and questionnaire fatigue. Instead of a questionnaire, patient-reported outcomes can be col...

Introduction Tendon transfers of the latissimus dorsi (LDT) or the lower trapezius (LTT) are treatment options for irreparable posterosuperior rotator cuff tears (PSIRCT). There is still no consensus on which type of tendon transfer is superior in the treatment of PSIRCT. Due to the differences in the anatomy and biomechanics, we hypothesize that...

Background This study aims to compare the range of motion (ROM) of reverse shoulder arthroplasty lateralised by bony increased offset (BIO-RSA) using a standard 38-mm (mm) component to regular reverse shoulder arthroplasty (RSA) lateralised by using a 42-mm glenoid component. The secondary aims are to compare patient-reported and radiographic outco...

Background The aim of this study was to use the Activities of Daily Living which require Internal Rotation (ADLIR) questionnaire to assess the functional internal rotation in patients who had undergone reverse shoulder arthroplasty (RSA) without reattachment of the subscapularis (SSc) tendon at a minimum follow-up of 2 years. The secondary aim was...

This chapter describes the indications, surgical techniques, and outcomes of tendon transfers in the setting of (revision) shoulder arthroplasty. Reverse shoulder arthroplasty (RSA) is effective in improving forward elevation and abduction, but rotation after RSA is less predictable. Tendon transfers can be used to compensate for a lack in rotation...

Introduction Despite technological advancements in recent years, glenoid component loosening remains a common complication after anatomical total shoulder arthroplasty (ATSA) and is one of the main causes of revision surgery. Increasing emphasis is placed on the prevention of glenoid component failure. Previous studies have successfully predicted r...

Background Plate osteosynthesis with implants made of carbon-fibre-reinforced polyetheretherketone (CFR-PEEK) has recently been introduced for the treatment of fractures of the proximal humerus (PHFs). The advantages of the CFR-PEEK plate are considered to be its radiolucency, its favourable modulus of elasticity, and the polyaxial placement of the...

Aims: The current evidence comparing the two most common approaches for reverse total shoulder arthroplasty (rTSA), the deltopectoral and anterosuperior approach, is limited. This study aims to compare the rate of loosening, instability, and implant survival between the two approaches for rTSA using data from the Dutch National Arthroplasty Regist...

Purpose/introduction: Over the last decades, there has been increasing interest in biological stimulation or bioaugmentation after rotator cuff repair. So far, there is no consensus on the appropriate composition of biologicals or which patients would benefit most, and moreover, these biologicals are often expensive. However, there are other, non-...

Aims The aim of this study is to report the implant survival and factors associated with revision of total elbow arthroplasty (TEA) using data from the Dutch national registry. Methods All TEAs recorded in the Dutch national registry between 2014 and 2020 were included. The Kaplan-Meier method was used for survival analysis, and a logistic regress...

Radial head and neck fractures represent up to 14% of all pediatric elbow fractures and can be a difficult challenge in the pediatric patient. In up to 39% of proximal radius fractures, there is a concomitant fracture, which can easily be overlooked on the initial standard radiographs. The treatment options for proximal radius fractures in children...

Clavicle fractures are commonly seen in the pediatric and adolescent populations. In contrast, congenital pseudarthrosis of the clavicle is rare. Although both conditions may present with similar signs and symptoms, especially in the very young, clear differences exist. Clavicle fractures are often caused by trauma and are tender on palpation, whil...

Background: In patients with total elbow arthroplasty (TEA), the soft-tissue around the elbow can be vulnerable to soft-tissue complications. This study aims to assess the outcomes after soft-tissue reconstruction following TEA. Methods: We retrospectively included nine adult patients who underwent soft-tissue reconstruction following TEA. Demog...

Aim A rare complication following volar plate fixation of a distal radius fracture is flexor pollicis longus (FPL) rupture. This study aims primarily to analyze the radiographic features and secondly to report the patient-reported outcomes of FPL reconstruction after volar plate fixation. Methods Ten patients were retrospectively identified and con...

Background The reported complication rate after Total Elbow Arthroplasty is high, and objective outcomes are not always predictive of satisfaction. This study aims to investigate the effect of a short-term complication on patient satisfaction and patient-reported outcome measures (PROM). Methods We retrospectively included 126 patients that receiv...

Background This study aims to use the Dutch Arthroplasty Register data to report an overview of the contemporary indications and implant designs, and report the short-term survival of radial head arthroplasty. Methods From the Dutch Arthroplasty Register, data on patient demographics, surgery and revision were extracted for radial head arthroplast...

This article aims to provide an overview of the current knowledge on the diagnosis and treatment of osteochondritis dissecans of the elbow. Osteochondritis dissecans is a disorder of the articular cartilage and subchondral bone, resulting in separation of the subchondral bone and overlying cartilage, and ultimately damage to the joint. Osteochondri...

National registries provide useful information in understanding outcomes of surgeries that have late sequelae, especially for rare operations such as total elbow arthroplasty (TEA). A systematic search was performed and data were compiled from the registries to compare total elbow arthroplasty outcomes and evaluate trends. We included six registrie...

Introduction Traumatic neuroma caused by injuries or surgery can result in neuropathic pain, functional impairment and psychological distress, which has an impact on quality of life. The aim of this study was to identify the factors related to successful treatment of symptomatic lower extremity symptomatic neuromas using patient-reported outcome me...
