Abstract
Background: Femoral neck fractures account for 3.6% of all fractures and are the most prevalent injuries among older people with high mortality and morbidity and among young, healthy people who sustain high-energy trauma.
Aim of the Work: To compare the clinical therapeutic effect of transverse cancellous lag screw (TCLS) fixations and ordinary cannulated screw (OCS) fixations for vertical femoral neck fractures.
Patients and Methods: This prospective randomized controlled study was conducted in Ain Shams University hospitals and El-Zaitoun hospital in Cairo. It included twenty two cases, who sustained femoral neck fractures. Patients were divided into 2 groups group A: using ordinary cannulated screws as a method of fixation. group B: using transverse lag screws as a method of fixation .a randomized controlled study involved twenty two cases, who complained of fracture neck femur femoral neck fractures.
Results: There was statistically significant slightly improved in TCLS group compared to OCS group. The results showed 5 patients out of 22 having complications, 2 patients (18.2%) belong to TCLS group compared to 3 patients (27.3%) belong to OCS group, with avascular Necrosis 1 patient (9.1%) in TCLS regarding Neck Shortening 1 patient (9.1%) in TCLS and 2 patients (18.2%) OCS group. Regarding Non Union 1 patient(9.1%) in OCS group, there was high complications in OCS group compared to TCLS group but insignificant.
Conclusion: The present study suggests that using the TCLS technique to treat vertical femoral neck fractures could improve hip functional outcomes and reduce the rates of neck shortening. The present study might provide insight for treatment of Pauwels’ type III femoral neck fractures.
