Enrollment: 4
Study Start Date: December 2009
Study Completion Date: June 2010
Intervention Details:
    Device: ExploR® Modular Radial Head
    The ExploR® Modular Radial Head is a modular head and stem radial head/neck replacement.
Detailed Description:

Data collection intervals are:

Pre-operative, Operative, 3 Months Post-op, 1 Year Post-op, 3 Years Post-op, and 5 Years Post-op.

Data collected includes:

Historical data, Operative record, Mayo Clinic Performance Index for the Elbow, Quick DASH Outcome Measure, Complications, Lost to Follow-up, Protocol Deviations, and Radiographic evaluation of elbow and wrist.


Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The study population will be implanted with the ExploR® Modular Radial Head.

Inclusion Criteria:

The inclusion criteria will be the same as the indications stated in the FDA cleared (510(k) K040611) and (510(k) K051385) labeling for the device.

  1. Replacement of the radial head for degenerative or post-traumatic disabilities presenting pain, crepitation, and decreased motion at the radio-humeral and/or proximal radio-ulnar joint with:

    1. Joint destruction and/or subluxation visible on x-ray
    2. Resistance to conservative treatment
  2. Primary replacement after fracture of the radial head
  3. Symptomatic sequelae after radial head resection
  4. Revision following failed radial head arthroplasty

The device is intended for single use with or without bone cement.

Modular Radial Head replacement prostheses have received FDA clearance for cemented and non-cemented application.

Patient selection factors to be considered include: 1) need to obtain pain relief and improve function, 2) ability and willingness of the patient to follow instructions, including control of weight and activity levels, 3) a good nutritional state of the patient, and 4) the patient must have reached full skeletal maturity.

Exclusion Criteria:

The exclusion criteria will be the same as the contraindications stated in the FDA cleared labeling (510(k) K040611) and (510(k) K051385) for the device. These contraindications include:

Absolute contraindications:

  1. Infection
  2. Sepsis
  3. Osteomyelitis

Relative contraindications:

  1. Uncooperative patient or patient with neurologic disorders who is incapable or unwilling to follow directions
  2. Osteoporosis
  3. Metabolic disorders which may impair bone function
  4. Osteomalacia
  5. Distant foci of infections which may spread to the implant site
  6. Rapid joint destruction, marked bone loss or bone resorption apparent on roentgenogram.
