- PublicationOpen AccessComparison of two types of proximal femoral hails in the treatment of intertrochanteric femur fractures(2015-09-01) Uzer, GÖKÇER; Elmadag, NUH MEHMET; Yildiz, FATİH; Bilsel, Kerem; Erden, TUNAY; Toprak, HÜSEYİN; UZER, GÖKÇER; ELMADAĞ, NUH MEHMET; YILDIZ, FATİH; BİLSEL, İSMAIL KEREM; ERDEN, TUNAY; TOPRAK, HÜSEYİNBackground: 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.

- PublicationMetadata onlyDoes performing total joint arthroplasty in the afternoon or evening increase the risk of prosthetic joint infection?(2020-11-01T00:00:00Z) YILDIZ, FATİH; ALIYEV, ORKHAN; ERDEN, TUNAY; GÜNGÖREN, NURDAN; UÇAN, VAHDET; TUNCAY, İBRAHİM; YILDIZ, FATİH; ALIYEV, ORKHAN; ERDEN, TUNAY; GÜNGÖREN, NURDAN; UÇAN, VAHDET; TUNCAY, İBRAHİMPurpose Does performing total joint arthroplasty in the afternoon or evening increase the rate of early prosthetic joint infection and the likelihood of early prosthetic joint infection? Methods We evaluated patients retrospectively, who underwent primary total hip (THA) or knee arthroplasty (TKA) between January 2016 and December 2019, met the inclusion criteria and had at least 90 days of follow-up. Patients were divided into two groups. Group I consisted of patients whose surgeries had been started and finished before 14:00, and group II included patients whose surgeries started after 14:01. All patients were operated after non-septic cases in specific orthopedic operating rooms. Their demographic data and comorbidities were noted. Primary outcome was to compare the risk of PJI between the groups. Results Group I and group II included 2309 and 1881 patients. Total number of patients with the diagnosis of PJI was 58 (1.4%). It was 31 (1.3%) and 27 (1.4%), respectively (p = 0.79). Performing total joint arthroplasty after 14:01 did not increase likelihood of infection (p = 0.83, OR 1.03). Among the parameters, PJI was significantly associated with age (p < 0.01, OR 0.99), smoking status (p < 0.01, OR 0.15) and operating time (p = 0.04, OR 0.99) in TKA and with direct anterior approach (p = 0.02, OR 4.72) in THA. Age (p = 0.06, OR 1.03) was the factor affecting the risk of subsequent PJI after total joint arthroplasty. Conclusion Performing total joint arthroplasty in the afternoon or in the evening, after aseptic cases does not increase the risk of subsequent of PJI.
- PublicationOpen AccessStraight 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 MEHMETObjective: 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.

We hypothesised that patients who have recurrent shoulder instability accompanied with generalised joint hyperlaxity tend to have acetabular dysplasia.
- PublicationMetadata onlyPeriprosthetic joint infection with streptococcus dysgalactiae subspecies equisimilis: Case report(2020-01-01T00:00:00Z) Erden, Tunay; Gultepe, Bilge Sumbul; KÜÇÜKDURMAZ, FATİH; ERDEN, TUNAY; SÜMBÜL, BİLGEStreptococcus dysgalactiae (SD) is a common pathogen among elderly population. However, to our knowledge, there is no periprosthetic joint infection case reported that is infected with Streptococcus dysgalactiae subspecies equisimilis (SDSE) in the English literature. In this article, we report a 77 -year -old male patient who had undergone total knee arthroplasty three years ago and had the diagnosis of cellulitis at his leg followed by swelling, pain and hyperemia localized at his knee. Three knee aspirations were performed and the SDSE was identified. There was no direct contact of patient to animals.

A total of 24 New Zealand rabbits were divided into four groups (Group I: multihole-drilling; Group II: Gigli saw; Group III: electrical saw blade and Group IV: laser). A proximal transverse diaphyseal osteotomy was performed on the right tibias of the rabbits after the application of a circular external fixator. The rabbits were killed six weeks after the procedure, the operated tibias were resected and radiographs taken.
