Background: To assess the midterm outcome of patients under 65 who underwent anatomic pyrocarbon hemiarthroplasty for thumb carpometacarpal (CMC) osteoarthritis.
Methods: A prospective analysis was performed of a consecutive series of active patients, less than 65 years of age, with symp- tomatic osteoarthritis who had undergone a CMC hemiarthroplasty using a stemmed metacarpal based, anatomic pyrolytic carbon resurfacing with an additional one third flexor carpi radialis (FCR) tendon transfer to maintain stability.
The Wrightington Hand Score, Disability Arm Shoulder and Hand (DASH) Score, and the Patient Rated Wrist Evaluation Score (PRWE) were utilised. Clinical data was obtained for grip strength, pinch strength, and range of motion.
Results: The MEAN age was 57.6 years. MEAN follow up was 6.5 years. All patients had improvement in pain, grip strength and function. There was no significant difference in grip and pinch strengths between the individual’s left and right hand. All patients stated that they would undergo the procedure again. There was one revision following a traumatic trapezium fracture. One patient underwent a neurolysis of a superficial radial nerve neuroma associated with an impinging trapezial osteophyte.
Conclusions: Active patients, under 65 years of age with Eaton-Littler stage III osteoarthritis of the thumb CMC joint who are treated with anatomic pyrolytic carbon resurfacing hemiarthroplasty and stabilisation may achieve sustained improvement in pain and hand function for up to 6.5 years.
