Abstract

Background

This study aims to use the Dutch Arthroplasty Register data to report an overview of the contemporary indications and implant designs, and report the short-term survival of radial head arthroplasty.

Methods

From the Dutch Arthroplasty Register, data on patient demographics, surgery and revision were extracted for radial head arthroplasties performed from January 2014 to December 2019. Implant survival was calculated using the Kaplan–Meier method.

Results

Two hundred fifty-eight arthroplasties were included with a median follow-up of 2.2 years. The most common indication was a fracture of the radial head (178, 69%). One hundred thirty-nine (68%) of the prostheses were of bipolar design, and the most commonly used implant type was the Radial Head System (Tornier; 134, 51%). Of the 258 included radial head arthroplasties, 16 were revised at a median of six months after surgery. Reason for revision was predominantly aseptic loosening (9). The overall implant survival was 95.8% after one year, 90.5% after three years and 89.5% after five years.

Discussion

For radial head arthroplasties, acute trauma is the most common indication and Radial Head System the most commonly used implant. The implant survival is 89.5% after five years.

Valgus stability of the elbow.

M. Weiland, John Hotchkiss (1986)

The valgus stabilizers of the elbow have been identified anatomically, but their relative importance has not been quantified. The purpose of this study was to analyze the acute changes of the torque-displacement curve to valgus stress following (a) section of the posterior portion of the medial collateral ligament; (b) excision of the radial head; (c) prosthetic replacement of the radial head; and (d) excision of the anterior portion of the medical collateral ligament. Thirty cadaver specimens underwent load-displacement testing in three positions: 0 degrees, 45 degrees, and 90 degrees of flexion. The anterior portion of the medial collateral ligament was the primary stabilizer of the elbow to valgus stress. The relative contribution of the posterior ligament was minimal. After excision of the radial head alone, the slope of the load-displacement curve decreased an average of 30%. Silicone rubber radial head replacement did not significantly improve the stability to valgus stress after radial head excision.

Arthroplasty with a metal radial head for unreconstructible fractures of the radial head.

Nicholas King, J Moro, Joy C. MacDermid … (2001)

Treatment of unreconstructible comminuted fractures of the radial head remains controversial. There is limited information on the outcome of management of these injuries with arthroplasty with a metal radial head implant. The functional outcomes of arthroplasties with a metal radial head implant for the treatment of twenty-five displaced, unreconstructible fractures of the radial head in twenty-four consecutive patients (mean age, fifty-four years) were evaluated at a mean of thirty-nine months (minimum, two years). There were ten Mason type-III and fifteen Mason-Johnston type-IV injuries. Two of these injuries were isolated, and twenty-three were associated with other elbow fractures and/or ligamentous injuries. At the time of follow-up, Short Form-36 (SF-36) summary scores suggested that overall health-related quality of life was within the normal range (physical component = 47 +/- 10, and mental component = 49 +/- 13). Other outcome scales indicated mild disability of the upper extremity (Disabilities of the Arm, Shoulder and Hand score = 17 +/- 19), wrist (Patient-Rated Wrist Evaluation score = 17 +/- 21 and Wrist Outcome Score = 60 +/- 10), and elbow (Mayo Elbow Performance Index = 80 +/- 16). According to the Mayo Elbow Performance Index, three results were graded as poor; five, as fair; and seventeen, as good or excellent. The poor and fair outcomes were associated with concomitant injury in two patients, a history of a psychiatric disorder in three, comorbidity in two, a Workers' Compensation claim in two, and litigation in one. Subjective patient satisfaction averaged 9.2 on a scale of 1 to 10. Elbow flexion of the injured extremity averaged 140 degrees +/- 9 degrees; extension, -8 degrees +/- 7 degrees; pronation, 78 degrees +/- 9 degrees; and supination, 68 degrees +/- 10 degrees. A significant loss of elbow flexion and extension and of forearm supination occurred in the affected extremity, which also had significantly less strength of isometric forearm pronation (17%) and supination (18%) as well as significantly less grip strength (p < 0.05). Asymptomatic bone lucencies surrounded the stem of the implant in seventeen of the twenty-five elbows. Valgus stability was restored, and proximal radial migration did not occur. Complications, all of which resolved, included one complex regional pain syndrome, one ulnar neuropathy, one posterior interosseous nerve palsy, one episode of elbow stiffness, and one wound infection. Patients treated with a metal radial head implant for a severely comminuted radial head fracture will have mild-to-moderate impairment of the physical capability of the elbow and wrist. At the time of short-term follow-up, arthroplasty with a metal radial head implant was found to have been a safe and effective treatment option for patients with an unreconstructible radial head fracture; however, long-term follow-up is still needed.

A review of national shoulder and elbow joint replacement registries.

Jeppe V Rasmussen, Bo S Olsen, Bjørg-Tilde S Fevang … (2012)

The aim was to review the funding, organization, data handling, outcome measurements, and findings from existing national shoulder and elbow joint replacement registries; to consider the possibility of pooling data between registries; and to consider wether a pan european registry might be feasible.
