Functional Outcome of Distal Radius Fractures Managed by Minimally Invasive Plate Osteosynthesis: A Prospective Study of 20 Patients.

Introduction: A distal radius fracture is a common injury that affects people of all ages. However, there are various therapy approaches that are controversial. Casting with or without closed reduction has long been considered a feasible option for treating distal radius fractures; alternative options include K-wire fixation and ligamentotax are with external fixation. However, with limited function and impairments, the results are frequently poor. "Several studies have found that distal radius fractures treated with external fixation have good anatomical and functional outcomes, although there is a substantial risk of pin tract infection and nerve damage. Internal fixation and classic open reduction frequently result in severe soft tissue dissection and periosteal damage, which can cause infection, delayed union, and non-union. Fortunately, a new approach known as minimally invasive plate osteosynthesis (MIPO) has recently evolved, which can reduce soft tissue stripping and bone vascularity loss while improving fracture healing.

Materials and methods: A prospective study of 20 patients with closed distal radius fractures was treated by the MIPO technique with a palmar locking plate between November 2022 and April 2023 and was followed up for 6 months.

Results: There were 12 females and 8 males with an average age of 54.2 years. The average blood loss was around 52 ml approximately. 11 patients obtained excellent results, 7 cases had good results and 2 patients had moderate effects. The average disabilities of the arm, shoulder, and hand score after 6 months was about 10.2.

Conclusion: In conclusion, two small incisions to implant a palmar locking plate by MIPO for distal radius fractures give good functional results as soft tissue handling is better compared to the conventional method of plating. But further research also should be carried out to explore more suitable treatment for specific individuals.
