Redisplacement of reduced distal radius fractures in adults: does the type of casting play a role? The CAST study, a multicentre cluster randomized controlled trial.

Aims: It is not clear which type of casting provides the best initial treatment in adults with a distal radial fracture. Given that between 32% and 64% of adequately reduced fractures redisplace during immobilization in a cast, preventing redisplacement and a disabling malunion or secondary surgery is an aim of treatment. In this study, we investigated whether circumferential casting leads to fewer the redisplacement of fewer fractures and better one-year outcomes compared with plaster splinting.

Diagnostic tests recommended for the clinical assessment of patients with wrist complaints, an e-Delphi study.

Background: Evidence-based practice for history-taking and physical examination in the evaluation of wrist complaints is limited.

Purpose: To create a set of recommended diagnostic tests for the clinical assessment of patients with undifferentiated wrist complaints.

Study Design: An e-Delphi study, following the recommendations on conducting and reporting Delphi studies, was performed.

Improved forearm rotation even after early conversion to below-elbow cast for non-reduced diaphyseal both-bones forearm fractures in children: a secondary 7.5-year follow up of a randomized trial.

Background And Purpose: previous RCT compared short-term results of above-elbow cast (AEC) with early conversion to below-elbow cast (BEC) in children with non-reduced diaphyseal both-bone forearm fractures. After 7 months both groups had comparable function. Our primary aim was to investigate whether forearm rotation improves or worsens over time.

Incidence and management of mallet finger in Dutch primary care: a cohort study.

Background: A mallet finger (MF) is diagnosed clinically and can be managed in primary care. The actual incidence of MF and how it is managed in primary care is unknown.

Aim: To determine the incidence of MF in primary care and to obtain estimates for the proportions of osseous and tendon MF.

Increased temporal binding during voluntary motor task under local anesthesia.

Temporal binding refers to a systemic bias in the perceived time interval between two related events, most frequently voluntary motor actions and a subsequent sensory effect. An inevitable component of most instrumental motor actions is tactile feedback. Yet, the role of tactile feedback within this phenomenon remains largely unexplored.

Posttraumatic Osteoarthritis of the Distal Interphalangeal Joint: A Follow-Up Study of 12 Years After Nonsurgical Treatment of Mallet Finger Fractures.

Purpose: In treatment of mallet finger fractures (MFFs), the aim is to minimize residual extension lag, reduce subluxation, and restore congruency of the distal interphalangeal (DIP) joint. Failure to do so may increase the risk of secondary osteoarthritis (OA). However, long-term follow-up studies focusing on OA of the DIP joint after an MFF are scarce.

Accuracy of 3D Corrective Osteotomy for Pediatric Malunited Both-Bone Forearm Fractures.

Re-displacement of a pediatric diaphyseal forearm fracture can lead to a malunion with symptomatic impairment in forearm rotation, which may require a corrective osteotomy. Corrective osteotomy with two-dimensional (2D) radiographic planning for malunited pediatric forearm fractures can be a complex procedure due to multiplanar deformities. Three-dimensional (3D) corrective osteotomy can aid the surgeon in planning and obtaining a more accurate correction and better forearm rotation.

Three-dimensional printed customized versus conventional plaster brace for trapeziometacarpal osteoarthritis: a randomized controlled crossover trial.

We investigated the non-operative management of trapeziometacarpal osteoarthritis with a three-dimensional (3-D) printed patient-customized brace compared with a conventional plaster brace. Fifty-two patients with symptomatic trapeziometacarpal osteoarthritis were enrolled in a 9-week crossover study, which was designed as a randomized controlled trial of two periods of 4-week brace therapies. The primary outcome was patient satisfaction measured with the Dutch version of the Quebec User Evaluation of Satisfaction with Assistive Technology questionnaire survey.

Psychometric qualities of the patient rated Wrist/Hand evaluation (PRWHE) in dutch primary care patients with wrist complaints.

Background: Knowledge on the course, disability and functionality of wrist complaints is still compendious in primary care guidelines, despite the high prevalence in primary care. Valid questionnaires can facilitate the monitoring of patients in primary care and research initiatives. In this study, we aimed to study the psychometric qualities of the Dutch version of the Patient Rated Wrist/Hand Evaluation (PRWHE-DLV) among adults with (sub)acute wrist complaints in primary care.

Morphological risk factors for scaphoid fracture: a case-control study.

Purpose: Most patients with a clinically suspected scaphoid fracture and normal initial radiograph are unnecessarily treated. Previously developed prediction rules using demographic and clinical risk are unable to accurately predict occult fractures. Adding other risk factors could enhance this.

Is Early Active Motion After 3-Ligament Tenodesis Noninferior to Late Active Motion? A Prospective, Multicenter Cohort Study.

Purpose: If early active motion after 3-ligament tenodesis is safe, it may yield more patient comfort and an early return to activities. Therefore, the aim of this study was to investigate whether early active motion is noninferior to late active motion after 3-ligament tenodesis for scapholunate interosseous ligament injuries.

Methods: This prospective, multicenter cohort study, using a noninferiority design with propensity score matching, compared a late active motion protocol (immobilization for 10-16 days, wrist therapy in weeks 5-6) with an early active motion protocol (immobilization for 3-5 days, wrist therapy during week 2).

Is Midcarpal Arthroscopy for Suspected Scapholunate Pathology Associated With Greater Interobserver Agreement and More Frequent Offer of Surgery?

Purpose: This study compared the interobserver agreement of arthroscopic classification of suspected scapholunate interosseous ligament (SLIL) pathology with and without midcarpal arthroscopy to help inform diagnostic strategies. It also measured the association of midcarpal arthroscopy with recommendations for reconstructive surgery. The association of midcarpal arthroscopy with the type of surgery recommended was also studied.

Beyond the pedicle screw-a patent review.

Purpose: This review provides an overview of the patent literature on posteriorly placed intrapedicular bone anchors. Conventional pedicle screws are the gold standard to create a fixation in the vertebra for spinal fusion surgery but may lack fixation strength, especially in osteoporotic bone. The ageing population demands new bone anchors that have an increased fixation strength, that can be placed safely, and, if necessary, can be removed without damaging the surrounding tissue.

Treatment Recommendations for Suspected Scapholunate Ligament Pathology.

 The diagnosis and treatment of scapholunate interosseous ligament (SLIL) pathology is debated and notably variable. This study assessed the influence of diagnostic arthroscopy on treatment recommendations and the interobserver reliability of the arthroscopic classification of SLIL pathology.  The influence of diagnostic arthroscopy on treatment recommendations and the reliability of the arthroscopic classification of SLIL pathology were tested in a survey-based experiment.

Do We Need to Stabilize All Reduced Metaphyseal Both-bone Forearm Fractures in Children with K-wires?

Background: Short-term follow-up studies have shown that reduced metaphyseal both-bone forearm fractures in children should be treated with K-wires to prevent redisplacement and inferior functional results. Minimum 5-year follow-up studies are limited. Range of motion, patient-reported outcome measures, and radiographic parameters at minimum 5-year follow-up should be evaluated because they could change insights into how to treat pediatric metaphyseal forearm fractures.

Outcomes of 3-D corrective osteotomies for paediatric malunited both-bone forearm fractures.

Closed treatment of paediatric diaphyseal forearm fractures carries the risk of re-displacement, which can lead to symptomatic malunions. This is because growth will not correct angulation deformity as it does in metaphyseal fractures. The purpose of this prospective cohort study was to evaluate the outcomes after 3-D-planned corrective osteotomy with patient-specific surgical guides for paediatric malunited forearm fractures causing impaired pro-supination.

The CAST study protocol: a cluster randomized trial assessing the effect of circumferential casting versus plaster splinting on fracture redisplacement in reduced distal radius fractures in adults.

Background: There is no consensus concerning the optimal casting technique for displaced distal radius fractures (DRFs) following closed reduction. This study evaluates whether a splint or a circumferential cast is most optimal to prevent fracture redisplacement in adult patients with a reduced DRF. Additionally, the cost-effectiveness of both cast types will be calculated.

The three-dimensional shape symmetry of the lunate and its implications.

We studied the three-dimensional (3-D) shape variations and symmetry of the lunate to evaluate whether a contralateral shape-based approach to design patient-specific implants for treatment of Kienböck's disease is accurate. A 3-D statistical shape model of the lunate was built using the computed tomography scans of 54 lunate pairs and shape symmetry was evaluated based on an intraclass correlation analysis. The lunate shape was not bilaterally symmetrical in (1) the angle scaphoid surface - radius-ulna surface, (2) the dorsal side and the length of the side adjacent to the triquetrum, (3) the orientation of the volar surface, (4) the width of the side adjacent to the scaphoid, (5) the skewness in the coronal plane and (6) the curvature of bone articulating with the hamate and capitate.

Below-elbow cast sufficient for treatment of minimally displaced metaphyseal both-bone fractures of the distal forearm in children: long-term results of a randomized controlled multicenter trial.

Background and purpose - We have previously shown that children with minimally displaced metaphyseal both-bone forearm fractures, who were treated with a below-elbow cast (BEC) instead of an above-elbow cast (AEC), experienced more comfort, less interference in daily activities, and similar functional outcomes at 7 months' follow-up (FU). This study evaluates outcomes at 7 years' follow-up.Patients and methods - A secondary analysis was performed of the 7 years' follow-up data from our RCT.

A radiostereometric and clinical long-term follow-up study of the surface replacement trapeziometacarpal joint prosthesis.

Background: The aim of this study was to determine long-term survival and clinical outcomes of the surface replacement trapeziometacarpal joint prosthesis (SR™TMC) and to evaluate implant migration using radiostereometric analysis (RSA).

Methods: In this clinical long-term follow-up study outcomes of ten patients who received the SR™TMC joint prosthesis were evaluated using DASH and Nelson scores, Visual Analogue Scale (VAS) of pain, and key pinch strength. RSA-radiographs were obtained direct postoperatively and 6 months, 1, 5 and 10 years postoperatively and were analyzed using model-based RSA software.

Diagnostic accuracy of history taking, physical examination and imaging for non-chronic finger, hand and wrist ligament and tendon injuries: a systematic review update.

Objective: The diagnostic work-up for ligament and tendon injuries of the finger, hand and wrist consists of history taking, physical examination and imaging if needed, but the supporting evidence is limited. The main purpose of this study was to systematically update the literature for studies on the diagnostic accuracy of tests for detecting non-chronic ligament and tendon injuries of the finger, hand and wrist.

Methods: Medline, Embase, Cochrane Library, Web of Science, Google Scholar ProQuest and Cinahl were searched from 2000 up to 6 February 2019 for identifying studies.

The role of concomitant ligament injury in the development of post-traumatic osteoarthritis after distal radius fractures: a protocol for a systematic review.

Introduction: Treatment of distal radius fractures (DRFs) aims to restore anatomic position of the fracture fragments and congruity of the articular surface to optimise functional outcomes and prevent osteoarthritis in the long term. While ligament injury of the wrist is often associated with DRFs and sole ligament injuries of the wrist lead to osteoarthritis, it is plausible that concomitant ligament injury in DRFs may aggravate degenerative changes of the wrist. The relationship between concomitant ligament injury and post-traumatic osteoarthritis in patients with DRFs is unclear.

Assessment of Flexion Elongation Relation and Type of Failure after Capsulodesis.

 Injury of the scapholunate interosseous ligament is the most frequently diagnosed cause of carpal instability and can be treated with a Mayo capsulodesis procedure. During this procedure, a radially based flap of the dorsal radiocarpal complex is attached to the lunate. The procedure attempts to reduce flexion of the scaphoid and restore the scapholunate relationship by crossing the scapholunate interval.
