A comparison of clinical outcomes between narrow and broad dynamic compression plate for femur fractures

Abstract

Purpose: To review the short term performance 4.5/5.0mm Wise-Lock Narrow Dynamic Compression Plate with LC under cuts and 4.5/5.0mm Wise-Lock Broad Dynamic Compression Plate with LC under cuts for femur fractures in terms of postoperative complications and failure rates. Methods: The total number of 46 patients, 24 to 55 years’ age group, who underwent internal fixation with wise-lock narrow and broad dynamic compression plate for femur fractures were reviewed. These implants were manufactured at Auxein Medical Private Limited Sonipat (India). The wise-lock narrow dynamic compression plates were implanted to 24 patients (18 Male and 05 Female) and broad dynamic compression plates were implanted to 22 patients (15 Male and 08 Female). These plates were made up of SS 316L and Ti6Al4V alloy respectively. Clinical and radiological follow-ups were conducted at the end of 30 days, 90 days, 180 days, 270 days and 365 days after surgery to examine the bone union, non-union & other related complications. During the one year of follow-up by the surgeon the patient's health status was analysed by the American society of anesthesiologists grade and the visual analogue score (VAS) was also determined. Results: Patients were followed up for one year. Out of 24 patients who were treated with wise-lock narrow dynamic compression plate, stainless steel, 04 patients (03 males & 01 female) were faced the complications of pain. However, out of 22 patients who were treated with broad dynamic compression plate, titanium, 02 patients (02 males) developed complications of pain. No biomechanical issue related to screw loosening, corrosion, bending, or other factors was not detected in 46 patients. Conclusions: Femur plate fixation is feasible for the treatment of femur fracture. The clinical outcomes and prognosis of patients are dependent on the accuracy of intraoperative reduction and surgical expertise.
