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: There is no consensus on the optimal operative technique for humeral shaft fractures. This meta-analysis aims to compare minimal-invasive plate osteosynthesis (MIPO) with open reduction internal fixation (ORIF) for humeral shaft fractures regarding non-union, re-intervention, radial nerve palsy, time to union, operation duration and functional outcomes.

METHODS: PubMed/Medline/Embase/CENTRAL/CINAHL were searched for both randomized clinical trials (RCT) and observational ...

PURPOSE: This study examined whether multidetector computed tomography (CT) is superior to bone scintigraphy for diagnosis of an occult scaphoid fracture.

METHODS AND MATERIALS: In a study period of 22 months, 100 consecutive patients with a clinically suspected scaphoid fracture and no fracture on scaphoid radiographs, were evaluated with CT within 24 hours after injury and bone scintigraphy between 3 and 5 days after injury. The reference standard for a true (radiographic occult) ...

BACKGROUND: 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 diagnostic performance characteristics when there is no consensus reference (gold) standard.

PURPOSES: We therefore compared the ...

OBJECTIVES: Some have suggested that MRI might be the best reference standard for a true fracture among patients with suspected scaphoid fractures. The primary aim of this study was to determine the rate of false-positive diagnosis of an acute scaphoid fracture in a cohort of healthy volunteers.

METHODS: In a prospective study, 33 healthy volunteers were recruited and both wrists of each were scanned, except for 2 volunteers for whom only one wrist was scanned. To simulate the usual ...

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 ...

Importance: Prehospital trauma triage protocols are used worldwide to get the right patient to the right hospital and thereby improve the chance of survival and avert lifelong disabilities. The American College of Surgeons Committee on Trauma set target levels for undertriage rates of less than 5%. None of the existing triage protocols has been able to achieve this target in isolation.

Objective: To develop and validate a new prehospital trauma triage protocol to improve current triage ...

BACKGROUND: This meta-analysis aimed to compare conservative vs. operative treatment for humeral shaft fractures in terms of the nonunion rate, reintervention rate, permanent radial nerve palsy rate, and functional outcomes. Secondarily, effect estimates from observational studies were compared with estimates of randomized clinical trials (RCTs).

METHODS: The PubMed/Medline, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and CINAHL (Cumulative Index to Nursing and ...

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) ...

The treatment after open and infected fractures with extensive soft tissue damage and bone deficit remains a challenging clinical problem. The technique described by Masquelet, using a temporary cement spacer to induce a membrane combined with reconstructive soft tissue coverage, is a possible solution. This study describes the work-up, operative procedure, complications, and the outcome of a homogenous group of patients with an open and infected tibia fracture and segmental bone loss ...

PurposeThe best diagnostic modality for confirmation of the diagnosis of a scaphoid fracture that is not visible on the initial radiograph (occult scaphoid fracture) is still subject of debate. The aim of this study was to compare the accuracy of magnetic resonance imaging (MRI), computed tomography (CT) and bone scintigraphy (BS) for the diagnosis of these occult scaphoid fractures.Patients and methodsIn a study period of 12 months, 33 consecutive patients with a clinically suspected ...

PurposeThe primary aim of this study was to assess the long-term quality of life and functional outcome after rib fracture fixation for patients with multiple rib fractures or flail chest. Secondarily, this study sought to identify risk factors associated with the quality of life.MethodsA retrospective cohort study with a follow-up by questionnaire was performed at a level-1 trauma center in Switzerland. All adult patients with three or more rib fractures treated with rib fixation ...

BACKGROUND: For the fixation of displaced midshaft clavicular fractures different plates are available, each with its specific pros and cons. The ideal plating choice for this lesion remains subject to ongoing discussion. Reconstruction plates are cheap and easily bendable, but their strength and stability have been questioned. The aim of this study was to evaluate the failure rate of reconstruction plates in the fixation of clavicular fractures.

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 ...
