We evaluated 100 consecutive patients with a suspected scaphoid fracture but without evidence of a fracture on plain radiographs using MRI within 24 hours of injury, and bone scintigraphy three to five days after injury. The reference standard for a true radiologically-occult scaphoid fracture was either a diagnosis of fracture on both MRI and bone scintigraphy, or, in the case of discrepancy, clinical and/or radiological evidence of a fracture. MRI revealed 16 scaphoid and 24 other ...

Background and aimsSince 1999, the Dutch trauma care has been regionalized into ten trauma systems. This study is the first to review such a trauma system. The aim was to examine the sensitivity of prehospital triage criteria [triage revised trauma score (T-RTS)] in identifying major trauma patients and to evaluate the current level of trauma care of a regionalized Dutch trauma system for major trauma patients.Patients and methodsMajor trauma patients (n=511) (June 2001–December 2003) ...

Early diagnosis and treatment of scaphoid fractures limits the number of delayed and non-unions. Bone scintigraphy proved to be a sensitive diagnostic tool for the detection of occult scaphoid fractures. However, the results have to be interpreted with care.

OBJECTIVE: To prospectively correlate the results of bone scintigraphy with clinical outcome.

METHODS: In a prospective study, we analysed 50 consecutive patients with signs of a scaphoid fracture at physical examination but no ...

The aim of this study was to evaluate prospectively the observer variation in the detection of pathology on MRI for suspected acute scaphoid fracture. 79 consecutive MR scans were included to calculate the inter-observer variation. All patients were suspected of having a scaphoid fracture but had no fracture on radiographs. 38 randomly chosen MR scans were used to calculate the intra-observer variation. Four observers, with varying levels of expertise, blinded scored three items: (i) ...

Fractures of the ankle are fairly common injuries. Open ankle fractures are much less common and associated with severe injuries to surrounding tissues. We have performed a systematic review of the literature concerning the clinical results and complication rates in the treatment of open ankle fractures. We conducted a search limited to the following databases: Pubmed/Medline, Cochrane Database of Systematic Reviews, Cochrane Clinical Trial Register and Embase. These were searched from ...

BACKGROUND: One of the new treatment options for proximal humeral fractures is the minimally invasive intramedullary nail. In this study, we reviewed the early clinical results after 1 year.

PATIENTS AND METHODS: 35 patients with proximal humeral fractures were treated using the Polarus nail. In 14 cases the initial treatment was operative; the other 21 patients were initially treated nonoperatively. 19 patients had a 2-part fracture, 5 had a 3-part fracture and 2 had a 4-part fracture. ...

Undisplaced scaphoid fractures are easily missed on conventional scaphoid radiographs, but these occult fractures may seriously impair hand function. Routine bone scintigraphy (BS) is often advocated if there are clinical signs of a scaphoid fracture without radiological evidence. However, the results require careful therapeutic management.

OBJECTIVE: To determine the diagnostic value of BS in daily practice for clinically suspected scaphoid fractures.

METHODS: We evaluated our protocol ...

BACKGROUND: The low prevalence of true fractures amongst suspected fractures magnifies the shortcomings of the diagnostic tests used to triage suspected scaphoid fractures.

PURPOSE: The objective was to develop a clinical prediction rule that would yield a subset of patients who were more likely to have a scaphoid fracture than others who lacked the subset criteria.

METHODS: Seventy-eight consecutive patients diagnosed with a suspected scaphoid fracture were included. Standardised ...

Bone scintigraphy will identify up to 25% of occult scaphoid bone fractures after negative scaphoid X-rays. Consequently, it deserves a place in the diagnostic process of suspected scaphoid fractures. However, the role of bone scintigraphy is less clear if scaphoid X-rays show other fractures in the carpal region. We analysed 111 consecutive patients with a suspected scaphoid fracture on physical examination. Scaphoid X-rays revealed 61 fractures. Fifty-five patients had scaphoid ...

PURPOSE: To examine the observer variation for bone scintigraphy in the detection of occult scaphoid fractures in daily practice, using only the early bone scanning images.

METHODS: One hundred bone scans of patients with a suspected scaphoid fracture but negative initial radiographs were prospectively included to calculate the inter- and intraobserver variation. Three nuclear medicine physicians independently evaluated all bone scans at 2 different points in time with a 3-month ...

The distal tibiofibular syndesmosis is important for stability of the ankle mortise and thus for weight transmission and walking. Syndesmotic injuries are most commonly associated with fibular fractures, but they can also occur in isolation or with damage to the lateral ankle ligament after traumatic supination. The need for trans-syndesmotic fixation of the distal tibiofibular joint has been controversial. The goal of this review was to collect evidence on the technical aspects of ...

Syndesmotic ruptures associated with ankle fractures are most commonly caused by external rotation of the foot, eversion of the talus within the ankle mortise, and excessive dorsiflexion. The distal tibiofibular syndesmosis consists of the anterior inferior tibiofibular ligament, posterior inferior tibiofibular ligament, and interosseous ligament, and it is essential for stability of the ankle mortise. Despite the numerous biomechanical and clinical studies pertaining to ankle fractures, ...

: To determine time trends of emergency department (ED) visits, hospitalization rates, spinal cord lesions and characteristics of patients with spinal fractures in the Netherlands.

METHODS: In an observational database study we used the Dutch Injury Surveillance System to analyse spinal fracture-related ED visits, hospitalization rates and spinal cord lesions between 1997 and 2012.

RESULTS: The total number of ED visits associated with spinal fractures increased from 4,507 in 1997 to ...

Isolated pubic ramus fractures are common fractures in the elderly, and treatment is typically non-operative. Up to 35 % of patients have a prolonged hospital stay due to pain. A small number of these patients do not respond to standard (non-operative) treatment. We retrospectively reviewed six patients with isolated pubic ramus fractures and persistent pain who were treated with percutaneous retrograde pubic ramus screw fixation. The study group consisted of six women with an average ...
