Treatment of non-displaced intracapsular femoral neck fractures with dynamic hip and cannulated screws resulting in avascular necrosis A comparative study of complications

Objectives: To compare the complications associated with cannulated hip screws (CHS) and dynamic hip screws (DHS) techniques. Methods: In this multicenter retrospective chart study, we reviewed the records and data of all patients operated upon by DHS or CHS for treatment of Garden type I and type I...

Description
Summary:Objectives: To compare the complications associated with cannulated hip screws (CHS) and dynamic hip screws (DHS) techniques. Methods: In this multicenter retrospective chart study, we reviewed the records and data of all patients operated upon by DHS or CHS for treatment of Garden type I and type II intracapsular non-displaced femoral neck fracture from January 2017 to December 2022. Patients with incomplete files or follow-ups of less than one year were excluded from the study. Results: The study enrolled 85 patients, 35 males, and 50 females, with a mean age of 72[+ or -]5.4 for males and 70.6[+ or -]7.6 for females. A total of 44 patients were operated upon with DHS, and 41 patients with CHS. The mortality rate of DHS was 15.9% and was 17.1% in the CHS group (p >0.05). Non-union was recorded in 4.5% of the DHS group and 4.9% of CHS patients (p >0.05). Avascular necrosis (AVN) was significantly higher in DHS (9.1%) than in CHS (4.9%, p<0.05). A revision was required in 15.9% of DHS patients and 14.6% of CHS patients (p >0.05). Conclusion: This study found that DHS was superior to CHS in AVN rate. However, there was no significant difference between both methods regarding mortality, revision, and non-union. Keywords: femoral neck fracture, internal fixation devices, complications
