    (2019) Kochai, Alauddin; Uysal, Mustafa; Ozalay, Metin; Cinar, Bekir Murat; Battal, Vahid; Avci, Mustafa Cagri
    Objectives: The ideal implant for the treatment of an unstable intertrochanteric femoral fracture is still a matter of discussion. Intramedullary nails with different varieties of design offer good options in treatment. The aim of this study was to compare two intramedullary nails in different design and reveal the differences by evaluating radiological parameters of patients with unstable intertrochanteric femoral fracture in mobile patients. Material and Method: PFN and INTERTAN nails in two groups were compared overall in 63 patients. Reduction quality and the differences on varus collapse and neck shortening of femur by measuring radiological parameters on early and late postoperative X-rays were examined. Results: Similar radiological results were found between PFN and INTERTAN nails. Reduction quality of fractures was similar between groups. There was a significant difference only in the varus collapse degrees between groups (p<0,001) but no difference in neck shortening. The results revealed that INTERTAN has better resistance to occur varus collapse and the same prevention for neck shortening. Conclusion: Implant design is the one of major factors that may affect the results. INTERTAN nail made a difference in varus collapse of the neck but not in neck shortening. The results of this study have shown that the nail with two adjacent lag screws provides slightly better fixation properties preventing varus collapse than the nail with two separate lag screws. INTERTAN and PFN are currently good options in the treatment of unstable intertrochanteric femoral fractures and sustain enough stability during healing period in mobile patients.

    Effect of PLIF and TLIF on sagittal spinopelvic balance of patients with degenerative spondylolisthesis
    (2018) Ozalay, Metin; Uysal, Mustafa; Derincek, Alihan; Kochai, Alauddin; Turker, Mehmet; 29705297
    Objective: The aim of this study was to evaluate the effects of PLIF and TLIF on sagittal spinopelvic balance and to compare radiological results of two surgical procedures with regard to spinopelvic parameters. Methods: Thirty-five patients (34 female and 1 male; mean age: 52.29 +/- 13.08 (range: 35-75)) with degenerative spondylolisthesis cases were included in the study. Patients were divided into two groups according to surgical technique: PLIF and TLIF. The level and the severity of listhesis according to Meyerding classification were assessed and spinopelvic parameters including sacral slope, pelvic tilt, pelvic incidence (PI), lumbar lordosis, and segmental lumbar lordosis were measured on digital X-rays. All preoperative and postoperative parameters and the results were compared between two groups. Results: The age distribution was similar in both groups (p = 0.825) and there was no difference between the mean PI of the groups (p = 0.616). In 15 patients, spondylolisthesis level were at the L5-S1 level (PLIF: 8, TLIF: 7), in 16 patients at the L4-L5 level (PLIF: 6, TLIF: 10) and in 4 patients at the L3-L4 level (PLIF: 2, TLIF: 2). According to Meyerding classification, before the operation, the sliding grades were 0 in 4 patients, 1 in 21 patients, 2 in 7 patients, and 3 in 3 patients. The grades changed into 0 in 28 patients, 1 in 5 patients, and 2 in 2 patients after surgery. There were no differences in the grade of listhesis between PLIF and TLIF groups preoperatively (p = 0.190) and postoperatively (p = 0.208). In both groups, the spondylolisthesis-related deformities of patients were significantly corrected after surgery (p < 0.001). Conclusion: PLIF and TLIF techniques have similar radiological results in restoring the sagittal spinopelvic balance in patients with degenerative spondylolisthesis. Both techniques are good options to achieve reduction and fusion in patients with degenerative spondylolisthesis, but have no advantage over each other for restoring spinopelvic balance.
