The effect of splint use duration on pronator quadratus muscle repair in the fixation of distal radius fractures using volar plates

Distal radius fractures are among the most common orthopedic traumas. Stable fractures can be successfully treated with closed reduction and casting. Fragmented and unstable fractures result in serious complications if they are not properly treated, and a large majority of intra-articular fractures are treated surgically. We hypothesized that the use of long arm splint for 10 days is enough to reduce the tear of the repaired PQ muscle and positively affect the clinical results. After fracture fixation, the PQ muscle was repaired along the radial margin, and three radiopaque hemoclips were attached to the radial margin of the muscle. Patients were divided into groups with 10 days or 20 days of splint application. Follow-up X-ray evaluations were performed at 10 and 20 days, and at 1, 2, and 3 months postoperatively. Hemoclip displacement of ≥1 cm following surgical follow-up indicated repair failure. The mean time from injury to surgery was 11.2 h. A total of 30 patients, 19 (63%) men, and 11 (37%) women, with complete follow-up records, were evaluated and divided into two groups based on splint use duration. The maximum change in hemoclip location was 6 mm. Hemoclip displacement was not detected in any of the 30 patients. No statistically significant differences were found between the two groups. PQ muscle repairs are generally durable after fixation of distal radius fractures with anatomical volar plates. The splint use duration had no radiological or clinical effects on the PQ repair.
