Open reduction and internal fixation of modified Mason type III/IV radial head fractures with more than three fragments: an analysis of the clinical outcome and reoperation rate.

Purpose: It is generally accepted that a radial head fracture (RHF) with more than three parts is not suitable for repair; therefore, most authors suggest straightforward radial head arthroplasty (RHA). With up to 20% risk for reoperation after RHA, improvement in reduction and fixation techniques may represent a valuable alternative before further extending the indications for arthroplasty. To determine the functional results and radiological failure rate after osteosynthesis of multi-fragmentary RHF with more than three articular fragments.

Hinge plate technique for osteosynthesis of comminuted proximal humeral fractures.

Background: Several surgical techniques of osteosynthesis have been described for treatment of proximal humeral fractures. There is evidence that the quality of reduction improves the clinical outcome and decreases the number of complications. Reduction of the medial calcar is tricky when standard manoeuvres are performed.
