PURPOSE: To describe fractures revealed by magnetic resonance imaging (MRI) in a series of skeletally mature patients with radial wrist pain after an acute injury and clinically suspected to have a scaphoid fracture. Additionally, we attempted to assess the diagnostic value of radiographs and computed tomography (CT) in patients with scaphoid and other carpal fractures verified by MRI.

METHODS: We conducted the study prospectively over a 3-year period on skeletally mature patients ...

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.

METHODS: During a six-year period (2004 to 2010) at two institutions, forty-four adult patients with a scaphoid waist fracture underwent ...

PURPOSE: To determine the incidence of associated intrinsic and extrinsic ligament injuries in patients with a nondisplaced or displaced scaphoid waist fracture.

METHODS: During a 3-year period, a study of all scaphoid fractures was performed at our institution. Diagnosis was confirmed by plain radiographs, computed tomography, and magnetic resonance imaging. A 3-part anatomic classification was used to categorize the scaphoid fractures. The study population comprised 40 patients with 41 ...

Background Union of a scaphoid fracture is difficult to assess on a standard series of radiographs. An unnecessary and prolonged immobilization is inconvenient and may impair functional outcome. Although operative treatment permits early mobilization, its influence on time to union is still uncertain. Purpose To assess union of scaphoid waist fractures based on computed tomography (CT) scan at 6 weeks, and to compare time to union between conservative treatment and arthroscopically ...

Although rupture of the extensor pollicis longus (EPL) tendon is a well-known complication of distal radial fractures, a number of patients rupture the EPL because of other conditions. We have retrospectively studied the aetiology of 27 ruptures of the EPL in 26 consecutive patients. Of 19 patients with injured wrists 12 had distal radial fractures, five had blunt trauma, and two had stab wounds that resulted in rupture. In the radial fractures operated on, the EPL rupture was caused by ...

PURPOSE: To evaluate clinical and radiological outcomes after conservative treatment and arthroscopic-assisted screw fixation of acute non- or minimally displaced scaphoid waist fractures in a randomized controlled trial.

METHODS: Consecutive patients with acute non- or minimally displaced scaphoid waist fractures were prospectively randomized to conservative or surgical treatment. All patients were screened using radiographs, computed tomography, and magnetic resonance imaging. ...

The operative treatment of mallet fractures of more than one third of the articular surface is controversial. The purpose of this study was to evaluate the complications and functional outcome of extension block pinning technique. Thirty-six consecutive patients with mallet fractures that involved more than one third of the joint surface were treated by extension block pinning a median of 3 days after injury (range 0-35, mean 7). Clinical outcome was graded according to Crawford's ...

Background and purpose - The epidemiology and optimal diagnostics of wrist injuries in children are not knotwn. We describe fractures revealed by magnetic resonance imaging (MRI) in a prospective population of children and adolescents with posttraumatic radial-sided wrist tenderness, and compare the diagnostic value of radiographs and computed tomography (CT) with that of MRI. Patients and methods - From 2004 to 2007, patients less than 18 years of age who presented at our emergency ...

PURPOSE: To identify factors associated with arthroscopically diagnosed scaphoid fracture displacement and instability.

METHODS: 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 part of a prospective protocol, and others to avoid a cast. All patients had preoperative computed tomography with ...

Osteonecrosis of the metacarpal head is rare and of unknown cause. We describe a 17-year-old girl with osteonecrosis of the fourth metacarpal head and a mutated prothrombin 20210A gene, which suggests a possible relation between a hypercoagulable state and osteonecrosis of the metacarpal head.

Twenty-seven patients with intraarticular fractures of the distal radius with a step of more than 1 mm in the joint surface after attempted closed reduction, were treated by reduction under arthroscopic control and percutaneous fixation. All fractures healed without measurable incongruity of the joint surface and at follow-up 3 to 38 months after surgery 19 patients had excellent and eight patients good results according to the Mayo modified wrist score.

PURPOSE: The aim of this study was to evaluate the functional, clinical, and radiological outcome 10 years after distal scaphoid fractures.

METHODS: From a prospective epidemiological study on posttraumatic radial-sided wrist pain, we evaluated 41 cases of distal scaphoid fractures. All cases had been treated nonsurgically in a thumb spica cast. Patients were examined using radiographs, magnetic resonance imaging and computed tomography at the time of injury and with computed tomography ...

BACKGROUND: The scaphoid is the most commonly fractured carpal bone in adults as well as in children. Previous studies have reported a wide range of fracture incidences. Scaphoid fractures and non-unions in children have been sparsely investigated.

AIM: To perform a systematic review of the current literature on epidemiology of scaphoid fractures and non-unions in adults and children.

METHODS: An electronic literature search was conducted investigating all studies in the literature ...
