Positional Screw Effect in the Treatment of Humeral Shaft Fractures Using a Minimally Invasive Plate Osteosynthesis...

Area of Science:

• Orthopedic surgery
• Traumatology
• Skeletal repair

Background:

• Humeral shaft fractures are common injuries.
• Minimally invasive plate osteosynthesis (MIPO) is a surgical technique used for fracture repair.
• The role of positional screws in MIPO for humeral shaft fractures requires further investigation.

Purpose of the Study:

• To compare clinical and radiologic outcomes of MIPO for humeral shaft fractures with and without a positional screw.
• To evaluate the impact of positional screws on fracture stability, healing time, and complications.
• To determine if positional screws enhance the effectiveness of MIPO in treating humeral shaft fractures.

Main Methods:

• Retrospective study of 63 patients with humeral shaft fractures treated with MIPO.
• Patients divided into two groups: MIPO without a positional screw (Group I) and MIPO with a positional screw (Group II).
• Comparison of functional outcomes (scores, range of motion), operation time, blood loss, complications, and radiologic outcomes (displacement, union time).

Main Results:

• No significant differences in sex, BMI, functional scores, fracture displacement, operation time, or blood loss between groups.
• Faster bony union observed in Group II (4.6 months) compared to Group I (6.4 months).
• Complications included transient radial nerve palsy and metallic failures, with no significant difference between groups.

Conclusions:

• Positional screws may enhance stability in MIPO for humeral shaft fractures, potentially leading to faster bony union.
• The use of a positional screw might aid in controlling interfragmentary movement crucial for fracture healing.
• MIPO with a positional screw could be a more stabilizing technique than bridge plating alone.
