Scaphoid fractures are common and notorious for their troublesome healing. The aim of this review is to reevaluate the current best evidence for the diagnosis, classification, and treatment of scaphoid fractures and nonunions. MRI and CT are used to establish a "definitive diagnosis" with comparable diagnostic accuracy although neither is 100% spec...
Objective To analyze the reproducibility, reliability, and demographics of a simplified anatomical scaphoid fracture classification based on posteroanterior radiographs using a large database of scaphoid fractures.
Methods The study consisted of a retrospective review of electronic medical records of 871 consecutive patients. All patients presented...
Purpose Using three-dimensional (3D) computed tomography models of acute scaphoid fractures, we looked for differences between volumetric size of the fracture fragments, recognizable groups, or a shared common fracture area.
Methods We studied 51 patients with an adequate computed tomography scan of an acute scaphoid fracture using 3D modeling. Fra...

Background:
Malunion is the most frequent complication seen after a fracture of the distal end of the radius. The primary aim of this study was to compare patient-reported outcome measures (PROMs) after corrective osteotomy for malunited distal radial fractures with and without 3-dimensional (3D) planning and use of patient-specific surgical guide...
Patellar dislocation is a condition that is often reduced by itself or through closed manipulation from a trained professional. In this case of a traumatic lateral patellar dislocation, the patella was caught through the rupture in the lateral retinaculum, as is seen in Boutonniere-like lesions. Reduction of the dislocated patella was obtained by a...
There is a great variety of classification systems with considerable controversies.In this chapter an overview is provided on different classification systems, all of which are based on radiographs. Thirteen different (sub)classification systems are found in literature based on (1) fracture location, (2) fracture plane orientation, and (3) fracture...
The scaphoid has characteristic anatomic features: it articulates with five adjacent bones through a largely cartilaginous surface and features a complex network of ligamentous attachments. A substantial variety in both osseous and ligamentous scaphoid anatomy has been described in literature. Variations in scaphoid anatomy are known to result in d...
Get a quick, expert overview of current diagnosis and management of scaphoid fractures with this concise, practical resource by Drs. Geert Buijze and Jesse B. Jupiter. This easy-to-read reference presents a summary of today's best evidence-based approaches to diagnosis and management in this critical area.
Importance
Fractures of the scaphoid are relatively common in young adults, with an incidence of 23 per 100 000. There has been a trend over the past decades towards surgical intervention, however, it was supported by limited evidence as we have reported previously. Using subsequently published data, this updated review will re-evaluate the pros an...

Coronal (or frontal plane) fractures of the scaphoid are distinctly uncommon. There are few published reports of coronal fractures of the scaphoid. This fracture is often missed on the initial X-ray films. A high index of suspicion should exist when there is a double contour of the proximal scaphoid pole on the anteroposterior X-ray view. A compute...
Purpose
In this anatomical cadaver study, the distance between major nerves and ligaments at risk for injury and portal sites created by trainees was measured. Trainees, inexperienced in elbow arthroscopy, have received a didactic lecture and cadaver instruction prior to portal placement. The incidence of iatrogenic injury from novice portal placem...
Background:
An intra-articular distal humerus malunion can be disabling. To improve function, reduce pain and/or prevent further secondary osteoarthritis an intra-articular corrective osteotomy can be considered. Herein we present the indications, practical guidelines for pre- operative planning and surgical technique. Subsequently, we provide lon...
Background In the lack of consensus, surgeon-based preference determines how acute scaphoid fractures are classified. There is a great variety of classification systems with considerable controversies.
Purposes The purpose of this study was to provide an overview of the different classification systems, clarifying their subgroups and analyzing thei...
Purpose:
There is no consensus on the relation between ulnar styloid process nonunion and outcome in patients with distal radius fractures. The aim of this study was to analyze whether patient-reported outcome is influenced by the nonunion of the accompanying ulnar styloid fracture in distal radius fracture patients.
Methods:
A meta-analysis of...

Purpose
The aim of this prospective randomized trial was to test the null hypothesis that there was no difference in the percentage of the fracture line of scaphoid waist fractures that demonstrated bridging bone on computed tomography (CT) 10 weeks after injury between patients treated in a below-elbow cast including or excluding the thumb.
Metho...
This thesis deals with current issues in anatomy, diagnosis and treatment of scaphoid fractures. Anatomical inconsistencies are elucidated by accurate 3D imaging. Sophisticated diagnostic imaging cannot solve the problem of the suspected scaphoid fracture because there is no gold standard for a true fracture, and there likely never will be. Acknowl...
Trapeziometacarpal arthrosis is expected with advancing age and a limited percentage of people seek medical attention for it. We studied patients after their first appointment to address trapeziometacarpal arthrosis with a hand surgeon to determine factors associated with return for a second visit and eventual election of operative treatment. A bil...
Resultaten Voor de primaire uitkomst was er een significant verschil in percentage van consolidatie op CT na tien weken (85% vs. 70%, p=0,048) ten gunste van de behandeling zonder duimimmobilisatie. Zes maanden na het ongeval waren er geen signi-ficante verschillen tussen beide groepen in polsbe-weeglijkheid, grijpkracht, MMWS-score, DASH-score, pi...
Background:
Fracture displacement is the most important factor associated with nonunion of a scaphoid waist fracture.We evaluated the performance characteristics of radiographs and computed tomography (CT) in the diagnosis of intraoperative displacement and instability of scaphoid waist fractures using wrist arthroscopy as the reference standard....

This study evaluated the functional outcome of corrective osteotomy for combined intra- and extra-articular malunions of the distal radius using multiple outcome scores.
We evaluated 18 skeletally mature patients at an average of 78 months after corrective osteotomy for a combined intra- and extra-articular malunion of the distal part of the radius...
A prospective study was performed to develop a clinical prediction rule that incorporated demographic and clinical factors predictive of a fracture of the scaphoid. Of 260 consecutive patients with a clinically suspected or radiologically confirmed scaphoid fracture, 223 returned for evaluation two weeks after injury and formed the basis of our ana...
BACKGROUND:
The diagnosis of displacement in scaphoid fractures is notorious for poor interobserver reliability.
QUESTIONS/PURPOSES:
We tested whether training can improve interobserver reliability and sensitivity, specificity, and accuracy for the diagnosis of scaphoid fracture displacement on radiographs and CT scans.
METHODS:
Sixty-four orthopae...
Missed research appointments may bias the outcome of prospective clinical trials if the participants that miss appointments differ in important ways from those that do not. The purpose of this study was to determine the predictors of missed research appointments in patients enrolled in clinical trials.

To identify factors associated with arthroscopically diagnosed scaphoid fracture displacement and instability.
This was a secondary use of data from 2 prospective cohort studies. The studies included 58 consecutive adult patients with a scaphoid fracture who elected arthroscopy-assisted operative fracture treatment: some for displacement, some as p...
The primary risk factor for nonunion of the scaphoid is displacement/instability, but delayed or missed diagnosis, inadequate treatment, fracture location, and blood supply are also risk factors. Untreated nonunion leads to degenerative wrist arthritis-the so-called scaphoid nonunion advanced collapse wrist. However, the correlation of symptoms and...
This report describes 2 patients with apparent ulnar to radial dorsal fracture-dislocation: 1 had a transtriquetrum, translunate fracture dislocation and the other had a reverse stage 2 lesser arc perilunate dislocation with fracture of the ulnar styloid at its base.
To determine the interobserver agreement and diagnostic performance characteristics of computed tomography (CT) for determining union of scaphoid waist fractures.
A total of 59 orthopedic and trauma surgeons rated for union a set of 30 sagittal CT scans of 30 scaphoid waist fractures. Of these fractures, 20 were treated nonoperatively, were imaged...
Using inaccurate quotations can propagate misleading information, which might affect the management of patients. The aim of this study was to determine the predictors of quotation inaccuracy in the peer-reviewed orthopaedic literature related to the scaphoid. We randomly selected 100 papers from ten orthopaedic journals. All references were retriev...

Forearm nonunions are uncommon but severely disabling and challenging to treat. Multiple factors have been associated with the establishment of forearm nonunions such as fracture location and complexity, patient characteristics and surgical technique. Treatment of diaphyseal forearm nonunions differs from that of other type of diaphyseal nonunions...
There are many controversies in the literature regarding the morphology of the scaphoid ligaments. The aim of this study was to provide a more accurate description by quantitatively describing the 3-dimensional, geometrical aspects of the scaphoid ligaments and their attachments, using cryomicrotome images of cadaveric wrists.
Eight fresh-frozen hu...
The interpretation of scaphoid anatomy and kinematics is confusing and controversial. This results from a lack of consensus on the anatomy of the ligaments attaching to the scaphoid and an overwhelming variety of substantially different anatomic descriptions and classification systems of the wrist joint in the literature. The present study systemic...
Perilunate dislocations are rare but complex injuries. Despite optimal management, they cause permanent impairment and disability in most patients. The aim of this chapter is to make recommendations based on current evidence regarding the diagnosis, treatment and prognosis of these injuries.
The effect of formal occupational therapy on recovery after open reduction and volar plate fixation of a fracture of the distal part of the radius is uncertain. We hypothesized that there would be no difference in wrist function and arm-specific disability six months after open reduction and volar plate fixation of a distal radial fracture between...
Recommendations for cast immobilization of acute scaphoid fractures vary substantially. We reviewed data from randomized controlled trials comparing nonoperative treatment methods for acute scaphoid fractures to determine the best available evidence.
A systematic search of the medical literature from 1966 to 2010 was performed. Two authors independ...
Evaluation of the diagnostic performance characteristics of radiographic tests for diagnosing a true fracture among suspected scaphoid fractures is hindered by the lack of a consensus reference standard. Latent class analysis is a statistical method that takes advantage of unobserved, or latent, classes in the data that can be used to determine dia...
We present a 24-year-old woman who sustained isolated nondisplaced fractures of the proximal carpal row after a low-energy injury. The radiographic features are most consistent with the recently described translunate arc injury and appear to be a transitional injury between an inferior arc injury as well as the greater and lesser arc injuries. The...
Information regarding the long-term outcomes of the treatment of lower-extremity fracture malunion and nonunion is lacking.
Twenty-nine secondarily referred patients with complex malunion or nonunion of the tibia or femur, treated by a single surgeon, were followed for a median of twenty years (range, twelve to thirty-five years) after injury. The...
Malunion is the most common complication of distal radius fracture. It has previously been demonstrated that there is a correlation between the quality of anatomical correction and overall wrist function. However, surgical correction can be difficult because of the often complex anatomy associated with this condition. Computer assisted surgical pla...
There is a current trend in orthopaedic practice to treat nondisplaced or minimally displaced fractures with early open reduction and internal fixation instead of cast immobilization. This trend is not evidence-based. In this systematic review and meta-analysis, we pool data from trials comparing surgical and conservative treatment for acute nondis...
Non-unions of the forearm often cause severe dysfunction of the forearm as they affect the interosseus membrane, elbow and wrist. Treatment of these non-unions can be challenging due to poor bone stock, broken hardware, scarring and stiffness due to long-term immobilisation.
We retrospectively reviewed a large cohort of forearm non-unions treated b...
Distal radius fractures are often associated with a fracture of the ulnar styloid at its base. This study tested the null hypothesis that there is no difference in outcome between patients with union and nonunion of a fracture of the proximal half of the ulnar styloid 6 months after volar plate fixation of a fracture of the distal radius.
A total o...
Anatomic reconstruction of proximal ulna and olecranon fractures allowing early mobilization and prevention of ulnohumeral arthritis.
Comminuted olecranon or proximal ulna fractures (including Monteggia fractures), olecranon fractures extending distally from the coronoid process, nonunions of the proximal ulna, segmental fractures of the proximal u...
In patients managed with plate fixation for the treatment of an olecranon fracture, the placement of an axial intramedullary screw may obstruct the placement of bicortical screws in the ulnar shaft. To overcome this problem, unicortical screws can be applied with use of a contoured locking compression plate. The present study was designed to assess...
New concepts in plate fixation have led to an evolution in plate design for olecranon fractures. The purpose of this study was to compare the stiffness and strength of locking compression plate (LCP) fixation to one-third tubular plate fixation in a cadaveric comminuted olecranon fracture model with a standardised osteotomy.
Five matched pairs of c...
A rare case of a 7-year-old boy with acute hematogenous osteomyelitis caused by Neisseria meningitidis serogroup C is presented. The diagnosis of osteomyelitis was made by bone scintigraphy and a blood culture confirmed meningococci as the cause of the disease. Meningococcal osteomyelitis is exceptionally rare and to our knowledge, serogroup C meni...
We report the case of a 58 year old male patient with nonproductive coughing, fever, vomiting and loss of appetite, beginning at the moment that he returned back home from a 2 week holiday in California. His symptoms were accompanied by increased inflammatory markers in his blood (leucocytosis, high CRP) and pulmonary sequelae, becoming more promin...
Substantial differences between disability and impairment are commonplace and puzzling. Subjective (psychosocial) factors may be paramount given that pain is a more important determinant of perceived overall arm-specific disability than is objective elbow impairment. To further evaluate the relationship between impairment and disability, we tested...
Irreparable posterior cuff tears can cause pain and lack of shoulder function. Surgical treatment includes musculotendinous transfers of either latissimus dorsi (LD) or teres major (TM). This study aimed to give a detailed description of the morphology of these two muscles with particular regard to their suitability for use in transfers. Sixty-two...
Irreparable ruptures of the subscapularis tendon represent a difficult surgical problem. An accepted treatment has been to utilize the pectoralis major as a transfer, using the superior half of the tendon, which involves parts of both the sternal and clavicular heads of the muscle. We undertook an anatomic study to investigate the possibility of us...
