    Does an infra pectineal plate alone provide adequate fixation in anterior column posterior hemitransverse acetabular fractures? A comparative biomechanical study
    (2022) Simsek, Ekin Kaya; Haberal, Bahtiyar; Mahmuti, Ates; Balcik, Bedi Cenk; Demirors, Huseyin; 0000-0002-1668-6997; 35920432; W-9080-2019
    BACKGROUND: The purpose of this study is to compare biomechanical properties of suprapectineal (SP) plate fixation, infrapectineal (IP) plate fixation, and both SP and IP plate fixation in anterior column posterior hemitransverse (ACPHT) fractures of the acetabulum using posterior and anterior column screws. METHODS: In 21 hard plastic left hemipelvis models, ACPHT fractures of the acetabulum were created, and in three different fixation groups, the methods were compared: Group 1: SP plating using a 3.5 mm reconstruction plate and cortical screw fixation, Group 2: Infrapectineal plating using 3.5 mm reconstruction plate and cortical screws combined with posterior and anterior column screws, and Group 3: Combined fixation with SP and IP plating using 3.5 mm reconstruction plates and cortical screws. Maximum load to failure (strength) of these three groups was compared between groups. RESULTS: The mean maximum load of failure for three groups was 2921 N, 2018 N, and 3658 N, respectively. When strength was compared considering the force that causing implant failure, it was determined that the strongest fixation was achieved when SP and IP fixation method were applied together, followed by SP only fixation and IP fixation supported by anterior and posterior column screws, respectively. CONCLUSIONS: The combined application of SP and IP fixation provides the most stable fixation of the ACPHT acetabular fractures, and IP fixation does not provide comparable biomechanical stability despite reinforcement with three-column screws placed away from the plate. Although IP fixation supported by anterior and posterior column screws with the limited combined approach is less invasive approach for patients, SP fixation should be included in the surgical treatment method to ensure adequate stability.

    Is simple decompression enough for the treatment of idiopathic cubital tunnel syndrome: A prosoective comparative study analyzing the outcomes of simple decompression versus partial medial epicondylectomy

    Objectives: This study aims to compare the clinical and functional outcomes of simple in-situ decompression and partial medial epicondylectomy for the treatment of idiopathic cubital tunnel syndrome (CuTS). Patients and methods: Between March 2014 and December 2016, 71 patients (31 males. 40 females: mean age 46.7 years: range. 38 to 62 years) with CuTS scheduled to undergo simple in-situ decompression (group 1) or partial medial epicondylectomy (group 2) were prospectively reviewed. All patients were analyzed with clinical examination (Tinel sign. Froment's and Wartenberg's signs, elbow flexion test, subluxation), and McGowan scores before and after surgery. Final outcomes were reviewed with Wilson and Krout grading system. Results: There was no significant difference between the study groups in regard to Wilson and Krout grading and McGowan scores postoperatively. Group 1 had significantly better grip and key pinch strength values compared to group 2 at the final follow-up control. Conclusion: In-situ decompression and partial medial epicondylectomy represent efficient and safe methods for the treatment of idiopathic CuTS. When their efficiency is compared. in-situ decompression had better grip and key pinch strength values and more excellent outcomes compared to partial medial epicondylectomy.
