Use of a Bone Graft Drill Harvester to Create the Fenestration During Arthroscopic Ulnohumeral Arthroplasty

Abstract

The Outerbridge-Kashiwagi procedure, or ulnohumeral arthroplasty, was described in 1978 as a method of treating elbow arthritis by creating a fenestration in the olecranon fossa. This fenestration diminishes the likelihood of recurrent spurs in the olecranon fossa and coronoid fossa, without loss of structural bony strength. Arthroscopic techniques have now been developed to perform this procedure. We describe an efficient method of creating the fenestration between the olecranon fossa and coronoid fossa during an arthroscopic ulnohumeral arthroplasty, or Outerbridge-Kashiwagi procedure, that also reduces the amount of residual bone debris produced during the resection.

Arthroscopic Transhumeral Ulnohumeral Arthroplasty

“…The Acumed ® Bone Graft Harvesting System is an ideal adjunct in these cases with a range of sizes that are suitable for fenestrating the olecranon fossa to create the transhumeral approach. The larger 12 mm reamer is an ideal size for most male patients, to efficiently remove bone and osteophyte from the olecranon fossa and create the transhumeral fenestration, whilst also removing the bone [16]. This window can then be carefully widened with an arthroscopic burr and shaver and residual anterior impinging bone removed with a Kerrison bone punch (Fig.…”
