Background: Hip nailing is frequently used to treat unstable intertrochanteric femoral fractures (ITF) in elderly patients. In this retrospective study, we compared the functional and radiological results, and the complications, of patients treated using proximal femoral nails (PFN) with an integrated, interlocking, compression lag screw, or two separate lag screws, which allow linear compression at the fracture site. Methods: A total of one hundred and eighteen patients were operated on for AO/OTA 31-A2 ITF between May 2010 and April 2012, and eighty-two of these patients, for whom sufficient follow-up data and documentation were available, were included into the study. PFNs with interlocking, integrated lag screws (Group I) were used in forty-four patients, and PFNs with two separate lag screws (Group II) in thirty-eight. Outcome parameters were the extent of varus collapse and leg length discrepancy on radiographs, and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Harris hip scores (HHS) as functional results. Results: Mean follow-up duration was 20 months (range, 12-36 months); fractures healed in all patients. Mean varus collapse values were 2.03±5.68° and 5.21±5.27° (p=0.01), Harris hip scores 73.2±11.65 and 74.72±11.15 (p=0.54), and WOMAC scores 70.78±11.41 and 71.78±11.19 (p=0.69) in Groups I and II, respectively. No difference was detected between the groups in terms of outcome parameters or complication rate. Conclusion: In the treatment of ITF, PFNs with an integrated, interlocking, compression lag screw, or two separate lag screws did not differ in terms of functional and radiological results or complication rate.

Straight Proximal Femoral Nails Mismatch with the Anterior Bowing of the Femur

2019-01-01T00:00:00Z, YILDIZ, FATİH, GÜZEL, YUNUS, ERDEN, TUNAY, KARA, DENİZ, ELMADAĞ, Nuh Mehmet, YILDIZ, FATİH, ERDEN, TUNAY, ELMADAĞ, NUH MEHMET

Objective: Increased anterior how of the femur due to advanced age and osteoporosis impinges with the distal part of the non-anatomic, standard proximal femoral nails (PFN), which is one of the most preferred implant for the fixation of trochanteric fractures (TF) in the elderly. The relation between increased femoral bowing and standard PFN application was investigated. Methods: Radiographs of 111 patients (59 men, 52 women; mean age 74.5 years), who were treated with PFN due to TF between 2011 and 2015, were evaluated retrospectively. Relation between the nail and the anterior cortex was determined by measuring the angle between distal anatomical axes of the nail and the femur (ADA). The patients were divided into two groups according to their ADA (group 1 ADA <= 4 degrees and group 2 ADA >4 degrees). Functional results and pain was evaluated using Harris Hip Score (HHS) and visual analog scale (VAS). Complications were also recorded. Results: The mean amount of ADA was 4.5 degrees +/- 1.5 degrees. Forty-seven patients were classified in group 1 and 64 patients were in group 2. The mean HHSs were 80.6 and 79.3 (p=0,464), and the mean VAS scores were 2.13 and 5.35 (p<0.001) in group 1 and 2, respectively. Five patients were revised due to cut-out of the lag screws (total hip arthroplasty in two patients and revision of the nails in three patients). Union was achieved in all patients without infection. Conclusion: Because straight femoral nails impinges anterior cortex of the femur with increased bowing, new design PFN with anterior curve is needed especially for shorter or osteoporotic people, or Caucasian population.

Comparison of Clinical Outcomes and Safety of Single-stage Bilateral and Unilateral Unicompartmental Knee Arthroplasty

2019-01-01T00:00:00Z, YILDIZ, FATİH, Erden, Tunay, UZER, GÖKÇER, TUNCAY, İBRAHİM, YILDIZ, FATİH, ERDEN, TUNAY, UZER, GÖKÇER, TUNCAY, İBRAHİM

Objective To evaluate the effectiveness and safety of bilateral Oxford medial unicompartmental knee arthroplasty (UKA) in the patients under a single anesthetic procedure. Methods: Between October 2013 and December 2015, 225 knees of 181 (age 67.5 years) patients with at least two years of follow-up were evaluated. They were divided into two groups as unilateral group (group 1, n=137) and one stage simultaneous bilateral group (group 2, n=44) for the comparisons. The outcome parameters were femoral and tibial component positions measured on the full-length radiographs, clinical outcomes using Oxford Knee Score (OKS), International Knee Documentation Committee Score (IKDC), patient reported satisfaction and complications. Results: Between the groups, the mean follow-up periods (p=0.125), age (p=0.447), preoperative body mass index (p=0.288), OKS (p=0.314) and IKDC (p=0.127) scores were not significantly different. Postoperatively, the mean flexion of the femoral component (p=0.544), posterior slope (p=0.511), varus-valgus angulation of the tibial components (p=0.358) were statistically similar berwcen groups. Although the mcan varus-valgus angulation of the femoral components (p=0.033) was statistically different between groups, the difference was too small to make clinical significance. The mean postoperative OKS (p=0.272) and IKDC (p=0.106) were similar between the groups. In group 1, 21 (16.0%) patients reported excellent, 91 (69.5%) good and 4 (3.1%) moderate satisfaction. Fifteen (11.5%) patients reported non-satisfaction. In group 2, patients reported excellent satisfaction in 20 (24.4%) knees, good in 50 (61.0%) knees patients moderate in 2(2.4%) knees. Patients reported non-satisfaction in 10 (12.2%) knees (p>0.05). Eight (5.8%) complications in group 1 and, 3 (3.4%) complications in group 2 were observed. The number of complications was not statistically different between the groups (p=0.535). Conclusion: One-stage simultaneous bilateral Oxford medial UKA is a safe and effective method with acceptable complication rates compared to unilateral surgery.
