Name

PHILOS (Fracture fixation in osteoporotic bone / proximal humerus)

 

Study Type

Observational prospective multicenter open cohort study

 

Question

The primary aim of this study is to evaluate if poor bone quality (determined by local Bone Mineral Density (BMD) 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).

Name

5th anchoring point

 

Study Type

Biomechanical study

 

Question

Varus failure is one of the most common failure modes following surgical treatment of proximal humeral fractures. Besides proximal and distal locking screws, straight antegrade nails (SAN) are supposed to be additionally anchoring in the proximal humeral cortex with the proximal nail's end. The aim of this biomechanical study was to investigate the characteristics of this "5th anchoring point". We hypothesized that the additional anchoring point would improve stability compared to the same construct without the 5th anchoring point.

Name

Proximal nail entry point

 

Study Type

Descriptive anatomical study

 

Question

Comparison of the ideal straight antegrade humeral nail's entrypoint on the humeral head, using 40 cadaveric humeri. Entrypoints will be determined using CT scans in the first step, and by "ideal" implantation of the physical nails into the real specimens.

Name

Allografting proximal humerus

 

Study Type

retrospective clinical study

 

Question

To augment the surgical fixation and to achieve postoperative stability strong enough to initially start full range of movement and to prevent secondary displacement in unstable fracture patterns and/or weak and osteoporotic bone. A bony allograft will be used. Long term clinical and radiological outcomes will be observed.

Name

Total shoulder arthroplasty

 

Study Type

retrospective clinical study

 

Question

The use of total shoulder arthroplasty (TSA) to treat primary glenohumeral osteoarthritis (GHOA) is increasing. Factors influencing patient satisfaction after surgery have not been well documented. The aim of this study was to determine demographic, radiologic and surgical factors predictive for satisfaction after TSA for GHOA.

Name

Autopsy

 

Study Type

retrospective clinical study

 

Question

In spite of increasing quality of emergency room (ER) assessment in trauma patients and improved accuracy of modern multislice computed tomography (MSCT), the number of potentially missed diagnoses is still controversial.

The aim of this study was to compare the initial findings of ER assessment and MSCT to the findings in autopsy in trauma patients not surviving the first 48 hours after admission. We hypothesized that autopsy was more accurate than MSCT in diagnosing potentially fatal diagnoses.

Name

After Treatment of proximal humeral fractures treated operative with philos plate: konservative fixed in a shoulder sling versus individual functional

 

Study Type

prospective, randomised, bicentric study

 

Question

The Primary aim of this study is to investigate the functional outcome after operative fixed proximal humeral fractures with two groups after treated in a different way, the study group functional from beginning on postoperative and the control group after treated konservatively 4 weeks in a shoulder sling only with passive motion through physio therapeut. The hypothese is, that patients of the individual scheme show better functional results.
