Pronator Quadratus Repair After Volar Plating of Distal Radius Fractures

Technical University of Munich

About

Investigation of the influence of the pronator quadratus (PQ) muscle repair following volar plate fixation of distal radius fractures with regard to the forearm pronation strength. During the early recovery period of 3 months an improvement of pronation strength and functional scorings was hypothesized for the PQ repair when compared to no repair.

Randomization of the patients in two groups ( PQ repair and no repair) and follow-up examinations after 6 and 12 weeks included bilateral isometric pronation strength measurement, range of motion, the QuickDASH and the Mayo-Wrist-Score, and a visual analogue scale (VAS)

Full description

Investigation of the influence of the pronator quadratus (PQ) muscle repair following volar plate fixation of distal radius fractures with special regards to the forearm pronation strength. During the early recovery period of 3 months an improvement of pronation strength and functional scorings was hypothesized for the PQ repair when compared to no repair.

Therefore the patients are randomized to group A = PQ repair and group B = no repair. Follow-up examinations after 6 and 12 weeks are scheduled included bilateral isometric pronation strength measurement, range of motion, the QuickDASH and the Mayo-Wrist-Score, and a visual analogue scale (VAS)

Enrollment: 60 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• isolated, closed fractures of the distal radius

• primary volar locking plate osteosynthesis within 7 days after trauma

Exclusion criteria

• concomitant fractures of the affected upper extremity
• intra-articular distal radius fractures ( type C)
• concomitant neurovascular injuries
• preexisting neurological illnesses
• initial external fixation

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

60 participants in 2 patient groups

PQ (Pronator quadraus) repair

Active Comparator group

Description:

Following volar plate osteosynthesis the pronator quadratus muscle is sutured with 3 to 5 U-shaped stitches using a polyfilament absorbable synthetic suture.

Treatment:

Procedure: Pronator quadratus repair

No PQ repair

No Intervention group

Description:

Following volar plate osteosynthesis the pronator quadratus muscle is placed in its anatomical position without suture repair.
