BACKGROUND Radial head prostheses are available with multiple geometric properties. The effect of design features on radiocapitellar stability has not been investigated. HYPOTHESIS The shape (depth and radius of curvature) of the articulating dish of a radial head prosthesis affects radiocapitellar stability. MATERIALS AND METHODS Radiocapitellar stability due to concavity-compression was e...

Radial head excision has always been a safe commonly used surgical procedure with a satisfactory clinical outcome for isolated comminuted radial head fractures. However, diagnosis of elbow instability is still very challenging and often underestimated in routine orthopaedic evaluation. We present the case of a 21-years old female treated with excision after radial head fracture, resulting in el...

This case is a 19-year-old soldier who suffered a combined elbow dislocation and posterior Monteggia fracture and dislocation (type II). The ulna fracture was managed by ORIF. The elbow dislocation was managed by closed reduction and immobilization in 900 flexion. The posteriorly dislocated radial head was kept reduced by a transarticular pin. After 6 months elbow and forearm motion was restric...

Background: Radial head fractures commonly occur during elbow traumas. Among those, treatment of Mason type IIIfractures is still under controversy. Common treatment methods for these fractures include open reduction and internalfixation (ORIF) as well as radial head excision. In this study, we compared long-term outcomes of both methods intreatment of patients with Mason type III fractures of ...

Comminuted fractures of the radial head still present signi ̄cant technical and surgical challenges. In this article, we describe a novel ̄xation of comminuted radial head fractures with the help of an intramedullary nail. Experiments with solid, conventionally machined intramedullary nails showed some major drawbacks in the ̄xation of radial head fractures. Several design and manufacturing proc...

INTRODUCTION Dislocation of the radial head, congenital or traumatic, anteriorly, posteriorly or laterally displaced, requires surgery to reseat and stabilize the head of the radius within the joint, in order to restore elbow flexion and, as much as possible, pronation-supination. SCOPE This article is meant to present the technique of proximal radial-ulnar ligament plasty using the extensor ...

BACKGROUND The posterior interosseous nerve (PIN) can be difficult to locate within the radial tunnel. The deep branch of the radial nerve (DBRN) enters the supinator muscle after passing under the arcade of Fröhse. It courses through the superficial portion of the supinator muscle to exit distally as the PIN. Anatomic landmarks could facilitate diagnosis and treatment of radial tunnel syndrome...

The radial head is an important structure that is crucial to the stability of both the elbow and forearm. Fractures of the radial head occur commonly and often are displaced or cause impingement to forearm rotation. Recent studies have further demonstrated the importance of maintaining or reconstructing the rigid buttress of the radial head. Advances in implant technology have benefited orthope...
