Summary
A 25-year-old female mandrill (Mandrillus sphinx - a primate and part of the Old World
monkey group) was presented with a mildly comminuted, diaphyseal, radial fracture
associated with a transverse ulnar fracture. Minimally invasive plate osteosynthesis
techniques were used to achieve fixation of both the radial and the ulnar fractures.
First, closed fracture reduction was achieved with a distraction frame consisting
of a motorized circular external skeletal fixator. Next, dual percutaneous radio-ulnar
plating was performed using a 2.7 limited-contact dynamic compression plate on the
cranial aspect of the radius and two stacked 2.0/2.7 veterinary cut-to-length plates
on the lateral aspect of the ulna. Uncomplicated recovery was observed with a complete
return to normal activity three months postoperatively. Fracture healing was documented
at four weeks, clinical union at 14 weeks, and callus remodelling at 24 weeks postoperatively.
This report demonstrates the feasibility of minimally invasive plate osteosynthesis
in a primate and shows the adaptability of this technique across mammalian species.
