“…Mason types II and III fractures are the least common radial head fracture types making up 14% and 19% of radial head fractures, respectively, according to van Riet et al Nevertheless, these fractures are often associated with ligament tears [4], and more specifically with MCL tears in 54% of cases [6]. In our study, the MCL was found to be torn in 23 of the 33 eligible patients (70%).…”

“…In a study evaluating the incidence of ligament injuries in displaced and comminuted radial head fractures, the MCL was found to be injured in 54% of elbows, the RCL in 80% and both ligaments in 50% of cases [6]. Schwab et al hypothesized why MCL tears often occur at the same time as the radial head fractures [7] (Fig.…”

“…The interosseous membrane (IOM) functions as another primary stabilizer of the elbow by providing longitudinal restraint to proximal migration of the radius during axial loading [21]. Radial head fracture or fracture/ dislocation is attended by a high incidence of ligament damage and repair of the collateral ligaments is critical to re-establishing normal joint biomechanics during surgical treatment of these injuries [14,16]. In an in vitro model, Pollock et al recently demonstrated repair of the lateral ulnar collateral ligament (LUCL) and MUCL restored elbow stability to varus and valgus stress, even in the presence of a displaced Type II coronoid fracture, suggesting evaluation and repair of the collateral ligaments is essential in cases of persistent instability [29].…”

Background The importance of the radial head to elbow function and stability is increasingly apparent. Although preservation of the native radial head is preferred, severely comminuted fractures may necessitate resection or arthroplasty. Silastic radial head arthroplasty has been condemned on the basis of several sporadic reports of silicone synovitis. However, problems of ''overstuffing,'' cartilage wear, and motion loss are becoming apparent with metal prostheses, indicating this also is not an ideal solution. Thus, the choices remain controversial. Questions/purposes We asked whether intact or reconstructed primary elbow stabilizers permit use of silastic radial head implants without fragmentation, failure, and silicone synovitis. Methods We retrospectively reviewed 23 patients with unreconstructable radial head fractures who were treated with silastic radial head arthroplasty and concomitant repair and/or reconstruction of the medial ulnar collateral ligament and/or lateral ulnar collateral ligament. Analysis included range of motion, pain, stability, and radiographic assessments; Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire; and Mayo Elbow Performance Score (MEPS). The minimum followup was 16 months (average, 69.6 months; range, 16-165 months). Results At last followup, the mean elbow flexion was 145°, extension 11°, supination 80°, and pronation 83°. The mean MEPS score was 88.9. The mean DASH score was 11.8. There were eight reoperations, none resulting from failure of the radial head implants. Conclusions These results demonstrate silastic radial heads can be used with low complication rates and without evidence of synovitis when concomitant elbow ligament repair or reconstruction is performed.
