About this study

Official title: The Influence of Local Bone Status on Complications After Surgical Treatment of Proximal Humerus Fractures

The purpose of this study is to evaluate if poor bone quality increases the risk of specific types of treatment complications in patients with proximal humerus fractures treated with open reduction and angle-stable plates (Proximal Humeral Internal Locking System - PHILOS).

Read the detailed description

More than 70% of patients with a proximal humerus fracture are older than 60 years, up to three quarters are women and the incidence of low-energy fractures increases exponentially with age. The standard diagnostic method for classifying osteoporosis is the measurement of Bone Mineral Density at specific body sites - hip, vertebra or distal radius. Despite the fact that osteoporotic fractures are very frequent at the shoulder, no study investigated the correlation between local bone quality and fracture treatment at the proximal humerus.

There is a concern among the clinicians that osteoporotic bone in proximal humerus fractures increases the risk of treatment complications. However, to our knowledge this has not yet been evaluated in clinical studies. One major reason for this lack of studies is the fact that no standardized method exists for the determination of bone density at the proximal humerus.

  25. Validation of a Computed Tomography (CT)-based method for BMD-measurement at the proximal humerus

    The BMD (mg/cm3) at the proximal humerus will be determined preoperatively for the contralateral side of the fracture with a general purpose CT scanner, according to the protocol. Briefly, a CT of the contralateral humerus is performed measuring simultaneously the European Forearm Phantom (EFP) applied on the patient's midthorax. The measured CT Hounsfield Units (HU) of user-defined ROIs can then be quantified with the EFPbased calibration curve, resulting in BMD-values.

    Measured: preoperative

  26. Association between the BMD at the proximal humerus (measured by CT) and the BMD at the distal radius (measured by DXA)

    Bone density measurements at the left and right proximal and distal humerus have been correlated by Diederichs and colleagues. BMD comparison between left and right humeri revealed higher correlations for the distal (R2 = 0.9) and the proximal humerus (R2 = 0.74) than comparison between proximal and distal humerus (R2 = 0.4) (97). These date suggest that the contralateral should be favored to the ipsilateral location when estimating the bone density of a fractured site.

    Measured: until 6 weeks postoperative

  27. Occurence of any complication

    To capture any complication that occured. A complication is defined as any occurrence or deviation from the normal treatment or outcome, regardless of whether it has any relationship with the treatment or product under investigation. The reported complication will be classified by AOCID as either serious or non-serious AE or as an anticipated complication.

    Measured: Baseline

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Local bone quality-related complication (time frame: From enrollment to 12 months postoperative). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01143675, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2020.
