Öğe Arthroscopic-assisted surgical treatment for developmental dislocation of the hip before the age of 18 months(SPRINGER, 2013) Ozturk, Hayati; Oztemur, Zekeriya; Bulut, Okay; Tezeren, Gunduz; Bulut, SemaThe purpose of this study is to evaluate the results of arthroscopy assisted surgical treatment of developmental dislocation of the hip (DDH). Arthroscopic assisted surgical treatment was performed on nine hips of nine female children with DDH using our method, published previously, between January 2001 and December 2005. Their ages ranged from 9 to 16 months. Percutaneous adductor tenotomies were performed in seven cases. A spica cast and abduction splint were used for 11-17 weeks postoperatively. Acetabular index and Shenton line were used for preoperative and postoperative radiologic evaluation. Also, the cases were evaluated postoperatively with respect to range of motion restriction, and the leg length discrepancy. The average follow-up was 47.7 months (range 22-79 months). Acetabular index measurements of cases in the preoperative/postoperative periods were as follows: preoperative mean angle 39.9A degrees (range 34A degrees-52A degrees)/postoperative mean angle 26A degrees (range 22A degrees-34A degrees). Hip joint restriction and leg length discrepancy were not observed postoperatively. However, two patients had acetabular dysplasia. Acetabular dysplasia was completely resolved in one patient in the third year of follow-up, whereas Salter innominate osteotomy, required in another patient, was in the second year of follow-up. The latter patient was the oldest case (16-month-old) in our series. Based on the results of this study, treatment of developmental hip dysplasia with arthroscopic-assisted surgical treatment technique may be safe and effective method. Further clinical studies will be required to confirm this study.Öğe Biomechanical properties of ciprofloxacin loaded bone cement(TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2013) Aslan, Talip Teoman; Oztemur, Zekeriya; Cifci, Mahmut; Tezeren, Gunduz; Ozturk, Hayati; Bulut, OkayObjective: The purpose of this study was to investigate the biomechanical properties of bone cement used in joint replacement surgery after the addition of ciprofloxacin. Methods: The first group received bone cement only and served as a control for the 4 groups where 500 mg, 1000 mg, 1500 mg and 2000 mg of ciprofloxacin were added to yield 40 g of bone cement. Axial compression tests were conducted using a 50,000 Newton capacity tension-compression testing device. Results: While axial compression strength at failure was 80.2 +/- 4.3 MPa in the control group, values in the ciprofloxacin-treated groups decreased with rising concentration of ciprofloxacin to 74.5 +/- 5.4 MPa, 70.6 +/- 4.8 MPa, 70.5 +/- 4.7 MPa, and 69.3 +/- 3.4 MPa. Conclusion: Bone cement with addition of 500 to 1500 mg ciprofloxacin maintained mechanical axial strength values above 70.0 MPa recommended by American Society for Testing and Materials and can be safely used in joint replacement surgery.Öğe Bladder Rupture and Urine Fistula Between-Bladder and Supracondylary Pin Tract After Pelvis Fracture: A case Report(DERMAN MEDICAL PUBL, 2015) Oztemur, Zekeriya; Golge, Umut Hatay; Picakci, Omer; Tezeren, Gunduz; Bulut, OkayOne of the most important complications of pelvic fractures is bladder rupture. Potential complications of pelvic fractures caused by bladder ruptures are vesicovaginal. vesicorectal, vesicoutedne and urethra rectal fistulas. Along with bladder rupture, which is rarely encountered in the literature, the case of urinary fistula from pin tract in femur supracondylar region was represented. The case of the bladder rupture induced by pelvic fracture that associated with urinary fistulisabon between bladder and pin tract from femur supracondylar region was reported.Öğe Comment on P.-T. Wu et al.: Acromio-clavicular dislocation with coraco-clavicular ligament clavicular avulsion fracture(SPRINGER JAPAN KK, 2013) Ozyurek, Selahattin; Atik, Aziz; Sivrioglu, Ali Kemal; Oztemur, Zekeriya; Incedayi, Mehmet…Öğe Delirium Awareness and Treatment Approach in Orthopedics Clinic(Aves, 2020) Pazarci, Ozhan; Kilinc, Seyran; Bekmez, Fatma; Cigdem, Burhanettin; Oztemur, ZekeriyaBACKGROUND/AIMS Orthopedic clinics are among the leading clinics in hospitals that request consultation for patients with delirium. However, delirium is often missed by nurses and physicians, resulting in an incorrect diagnosis. This study aimed to identify patients with delirium in the orthopedic clinics and describe our approach for these patients. MATERIAL and METHODS After forming a strategy for the diagnosis, treatment, and follow-up of patients with delirium, prospective follow-up was performed for patients hospitalized in the orthopedic ward. High-risk patients were screened using the Nursing Delirium Screening Scale, and patients diagnosed with delirium were evaluated using a prepared form. This approach was used to determine the risk factors for delirium, ensure patient safely, and treat the symptoms of delirium. RESULTS Total 988 patients were evaluated, and 34 (2.44%) were diagnosed with delirium. The mean age of the patients was 66.17 +/- 22.68 years. The mean duration of delirium was 2.88 +/- 0.84 days. An age group-based comparison showed that the duration of delirium in older patients was significantly longer than that in younger patients (3.08 +/- 0.9 vs. 2.45 +/- 0.52 d, p=0.042). Further, delirium duration was more among men than among women (3.0 vs. 2.2 d, p=0.031). CONCLUSION Rapid identification of delirium and determination of the etiological cause allows timely and appropriate correction of the condition Identification of delirium by the medical team and the use of a systemic approach are important in treatment. The duration of delirium is longer in men and the elderly; further, most delirious patients have more than one risk factor for delirium.Öğe Detection of Bone Excretion with Current Sensor in Robotic Surgery(IEEE, 2018) Torun, Yunis; Ozturk, Ahmet; Hatipoglu, Nursu; Oztemur, ZekeriyaBone drilling operation is widely used method in surgery. This operation must be done with hight care. In the case of failur some demage might be happened. In this paper a new technich is presented. By this method 1,5 mm precision is optained.Öğe Effect of Extracorporeal Shock Waves on Subcondylar Mandibular Fractures(LIPPINCOTT WILLIAMS & WILKINS, 2012) Altuntas, Emine Elif; Oztemur, Zekeriya; Ozer, Hatice; Muderris, SuphiObjective: The purpose of this pilot study was to evaluate the effects of extracorporeal shock wave therapy on healing of subcondylar mandibular fracture in rats. Methods: Unilateral subcondylar fracture in 20 Wistar albino rats was used as a fracture model. Each rat was anesthetized 1 day after surgery, and extracorporeal shock wave therapy was performed. On the 21st day after surgery, animals were killed. Mandibles were dissected, all soft tissues were removed after sacrifice, and fractured and nonfractured hemimandibles were obtained from each rat. Histologic analyses were performed by a single pathologist blinded to the samples. Results: The specimens' mean score in bone fracture healing was 7 (1.09) (range, 6-9) in group 1 and 2.57 (1.62) (range, 1-6) in group 2. With respect to the specimens' bone fracture healing score, there was a statistically significant difference between the 2 groups. Conclusions: As a result, our study showed that extracorporeal shock wave therapy accelerated the improvement of fractures in experimentally induced subcondylar mandibular fracture in the rat mandible. We believe that reducing the duration of improvement in subcondylar mandibular fractures by intermaxillary fixation along with extracorporeal shock wave theraphy would contribute to preventing complications such as ankylosis, fibrosis, and hypomobility occuring because of prolonged fixation.Öğe Effect of high-energy extracorporeal shock waves on the immature epiphysis in a rabbit model(SPRINGER, 2008) Ozturk, Hayati; Bulut, Okay; Oztemur, Zekeriya; Kaloglu, Celal; Kol, Iclal OzdemirIntroduction We investigated the effect of high-energy extracorporeal shock wave (ESW) on immature tibial epiphysis in a rabbit model. Materials and methods Twenty New Zealand white immature rabbit were used in this study. Animals were divided into two groups and they received 14 kW, 0.6 mJ/mm(2), 1,500 or 3,000 shots for three times with an interval of 7 days. After 6 weeks all rabbits were killed. The all tibia epiphysis were assessed by histology. The epiphyseal plaque thickness of right tibiae of the 3,000-shot ESW group was significantly higher than those of the 1,500-shot ESW group and the left tibia epiphyses of the 1,500- and 3,000-shot ESW groups as controls (P < 0.05). Results The epiphyseal plaque thickness of right tibiae of the 1,500-shot ESW group was significantly higher than that of the left tibia epiphyses of the 1,500- and 3,000-shot ESW groups as controls (P < 0.05). Discussion We demonstrated that high-energy ESW stimulated the growth of immature rabbit epiphysis. The long-term effect of shock wave on the immature rabbit epiphysis deserves further study.Öğe The effect of intravenous pamidronate treatment for type i osteogenesis imperfecta patients have on their bone mineral density, fracture rate, and mobility(DRUNPP-SARAJEVO, 2012) Oztemur, Zekeriya; Ozturk, Hayati; Circi, Esra; Bulut, Okay; Uner, Serdar; Altun, Ahmet; Tezeren, GunduzObjective: Osteogenesis imperfecta (OI) is a genetic disorder caused by the mutation in encoding collagen type I, and characterised by fragile bone and reduced bone mineral density. The purpose of this study was to analyse the effects siklik intravenous pamidronate treatment has on the bone mineral density and the fracture rateand mobility. Patients and Methods: The sample group of this study comprises of 7 patients (6 male (85.7%), 1 women (14.2%) with type I OI, who received intravenous pamidronate, between August 2004 and October 2010. The intravenous dose of pamidronate disodium (Aredia, Novartis) was 0.75 mg/kg of the body weight, administered as a single dose every 6 months, over 8 hours in a saline solution. Bone mineral density was measured before and after the treatment using a dual energy X-ray absorptiometer at vertebral bodies from L1 to L4. Bone mineral density (g/cm(2)), T scores and Z scores, number of fractures, and modified Bleck scores were recorded. Results: The median age of patients at the time of treatment was 15 years (min: max=13: 18), the median BMI was 17.86 (min: max=14.29: 20.68) kg/m(2), the median follow-up period was 36 (min: max=12: 72), and the median number of doses received was 5 (min: max=1: 20). The median bone mineral content was increased from 0.368 (min: max=0.23-0.59) to 0.628 (min: max=0.53: 0.88) (p=0.02), the median T score was increased from -6.6 (min: max=-7.50: -1.90) to -4.2 (min-max=-5.10:-1.90) (p=0.043), the median Z score was increased from -4.91 (min: max=-7.7: -3.2) to -3.9 (p=0.144), and the median modified Bleck score was increased from 6 (min: max=2: 9) to 9 (min: max=: -7.7: -3.2) (p=0.043). The median numbers of fracture decreased from 0.40 (min: max=0.15: 0.76) to 0 (min: max: 0: 1) per year (p= 0.540). Conclusion: Intravenous pamidronate in patients with OI increased bone mineral density and patient's mobility, and improved the fracture rate. Pamidronate is a safe and effective treatment method in patients with OI.Öğe THE EFFECT OF LOW DOSE TEICOPLANIN-LOADED ACRYLIC BONE CEMENT ON BIOCOMPATIBILITY OF BONE CEMENT(AKADEMIAI KIADO ZRT, 2013) Oztemur, Zekeriya; Sumer, Zeynep; Tunc, Tutku; Pazarci, Ozhan; Bulut, OkayAntibiotic-loaded acrylic bone cement (polymethylmethacrylate, PMMA) is used to prevent or treat infection in total joint replacement surgery. The purpose of this study was to investigate biocompatibility and cytotoxicity of the teicoplanin-loaded acrylic bone cement. Cytotoxicity examination of acrylic bone cement balls and 400 mg teicoplanin added acrylic bone cement balls conducted by MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay. SEM (Scanning electron microscopy) was used to observe adhesion and spreading of cells on surface of the balls. Cytotoxicity examination conducted by MTT assay on acrylic bone cement balls and teicoplanin-added acrylic bone cement balls revealed no cytotoxicity. SEM analysis put forward that cells started to proliferate and adhere on surface of the samples in both groups as a result of 48-hour incubation and that the cell proliferation over acrylic bone cement and teicoplanin-added acrylic bone cement was similar. As a consequence, there was no cytotoxicity in acrylic bone cement and teicoplanin-added acrylic bone cement groups according to results of MTT assay. On the other hand, results of SEM showed that biocompatibility of both groups was similar. In conclusion, teicoplanin-loaded bone cement did not change biocompatibility of bone cement in studied dose.Öğe Effect on mortality of treatment method and surgery time for hip fracture patients aged over 65 years(Turkish Assoc Trauma Emergency Surgery, 2020) Ekici, Cihat; Pazarci, Ozhan; Kilinc, Seyran; Oztemur, Zekeriya; Ozturk, Hayati; Tezeren, Gunduz; Bulut, OkayBACKGROUND: This study aimed to evaluate the effects on mortality of implant selection used and time to surgery in patients aged over 65 years operated for hip fractures. METHODS: A total of 301 patients aged over 65 years were investigated in this study. Patients were divided into three groups as follows: Group 1 cemented hemiarthroplasty (CH), Group 2 cementless hemiarthroplasty (CLH), and Group 3 proximal femoral nail (PFN). Time of surgery, fracture and demographic information were retrospectively recorded. RESULTS: After removing 59 patients with missing information, this study included 242 patients. Mean age of patients was 80.5 years. When patient groups were examined according to treatment method, Group 1 (n=146) comprised 60.3%, Group 2 (n=54) comprised 22.3% and Group 3 (n=42) comprised 17.4% of the study group. There was no significant difference in survival between the patients operated in the first 48 hours and the patients operated later (p=0.834). There was an effect on the survival of treatment implant selection (p=0.016). Patients with CH were observed to survive longer than patients with CLH and PFN. CONCLUSION: Operation in the first 48 hours was not observed to affect mortality. Additionally, while sex and age were found to be effective on mortality, implant selection was also concluded to affect mortality.Öğe Evaluation of proprioception in patients who underwent ACL reconstruction: measurement in functional position(Tubitak Scientific & Technological Research Council Turkey, 2021) Suner Keklik, Sinem; Guzel, Nevin; Cobanoglu, Gamze; Kafa, Nihan; Ataoglu, Muhammet Baybars; Oztemur, ZekeriyaBackground/aim: Anterior cruciate ligament (ACL) injuries cause mechanoreceptor loss in the joint; therefore, proprioceptive deficits are observed after injury. In particular, proprioceptive measurements made in the functional position give more accurate results, and this is an area that requires further studies. This study aimed to evaluate proprioception in patients who had undergone ACL reconstruction (ACLR) in functional positions used in daily life (closed kinetic chain position), according to joint angles where ACL injuries occur more frequently, in comparison with healthy controls. Materials and methods: Thirty-four participants who underwent ACLR using a hamstring tendon graft (aged 29.18 +/- 8.16 years; body mass index (BMI), 26.58 +/- 4.02 kg/cm(2)) and 31 healthy participants (aged 27.35 +/- 5.74 years; BMI, 24.76 +/- 2.98 kg/cm(2)) were included. Proprioception was assessed with an active angle repetition test, using an inclinometer in the closed kinetic chain position while standing. Participants were asked to perform single-leg squats until the angle at the knee joint was 30 degrees. After the targeted angle was defined, the participants were asked to find the targeted angle. The difference between the targeted angle and the angle reached by the participants was calculated. Results: A statistically significant difference in the active joint position sense was found among the ACLR extremity, uninvolved extremity, and control extremity (p < 0.05). The proprioceptive sense between the two extremities in the ACLR group was similar, and the proprioceptive sense was worse than that of the control group. Conclusion: To our knowledge, this is the first study to evaluate closed kinetic chain position in patients who underwent ACLR, and it showed that proprioceptive sense was still poor in patients with ACLR compared with the control group, even if an average of 24 months have elapsed since surgery.Öğe Extreme complications of Fixion nail in treatment of long bone fractures(SPRINGER, 2008) Ozturk, Hayati; Unsaldi, Tansel; Oztemur, Zekeriya; Bulut, Okay; Korkmaz, Murat; Demirel, HueseyinThe authors present their experience related to extreme complications in treatment of diaphyseal fractures of the long bones with application of the Fixion expansion intramedullary nail in a total of 48 surgeries. We have encountered six (12.5%) extreme complications in the management of fractures of 3 humeral, 2 tibial, and 1 femoral bones during its application procedure and postoperative follow-up. Of six cases, two with humeral and tibial fractures developed nonunion and rotational instability because of failure of inflation of the Fixion nail. One of the Fixion nail in humerus was broken spontaneously, and one of the Fixion nail deflated at the follow-up and pseudoarthrosis developed in this patient. In a patient with osteogenesis imperfecta, during the inflation of the nail for the treatment of femur fracture, a new longitudinal fracture occurred and conventional non-locking intramedullary nail was inserted. In a patient with a tibia fracture that was treated with the Fixion nail, new fracture occurred due to its bending after weight bearing in the postoperative period. The Fixion nail application is a new technique for the intramedullar fixation of long bones. It is considered as an effective method for the selective fracture types of long bones. Application may need special training. Since the Fixion has not got rotational stability and rigidity as conventional nailing systems, bending and breaking of the nail may occur during postoperative period in patients with over obesity and hyperactivity. In patients with osteogenesis imperfecta, it may not be the first choice as a nailing system.Öğe FOXP3 rs3761548 polymorphism is associated with knee osteoarthritis in a Turkish population(WILEY, 2018) Cekin, Nilgun; Pinarbasi, Ergun; Bildirici, Aslihan Esra; Donmez, Gonca; Oztemur, Zekeriya; Bulut, Okay; Arslan, SerdalAim: Functional polymorphisms located in FOXP3 intron 1 was recently found to be associated with rheumatoid arthritis (RA). Although RA is an autoimmune disease, there is supporting evidence that activated maladaptive responses including pro-inflammatory pathways play roles in osteoarthritis (OA), similar to RA. The aim of this study was to explore the relationship between rs2232365 (-924A/G) and rs3761548 (-3279A/C) polymorphisms as well as possible changes in the 600 bp promoter region of FOXP3 and knee OA. Methods: Patients with primary knee OA (n = 300) and healthy individuals (n = 300) were examined for rs3761548 and rs2232365 FOXP3 gene polymorphisms by the polymerase chain reaction-restriction fragment-length polymorphism method. The 600 bp promoter region (between -500 and +100) of the gene was also sequenced with direct sequencing in 50 knee OA patients and 50 healthy individuals. Results: There were no sequence variants in the promoter region tested both in OA patients and healthy controls. The SNP rs2232365 showed no association with OA susceptibility and severity and the results of other genetic models were also nonsignificant. On the other hand, rs3761548 AC (P = 0.003), AA + CC (P = 0.0014) as well as AC + AA (P = 0.40) genotypes showed association with Grade 4 knee OA patients. Conclusion: Our findings indicated that the association between FOXP3 rs2232365 polymorphism and knee OA tended to yield negative results but the FOXP3 rs3761548 C allele was associated with elevated risk of OA in Grade 4 knee OA patients in a Turkish population.Öğe If the Airway Opens with Finger During Epileptics Attack: A Case Report(DERMAN MEDICAL PUBL, 2015) Kilinc, Seyran; Ortucu, Abdulrahman; Bulut, Okay; Tezeren, Gunduz; Oztemur, ZekeriyaThe human bites generally have been came across after the situation as fighting, aggression, murder, sports competitions and child abuse. Hands and wrists are the most common areas that human bites have seen. Our case was seen first time when 65 aged woman treating for diabetes mellitus in our endocrinology service consultated us with a neglected open wound that occurred after she put on her hands second finger's proximal phalanx to her relative's mouth to keep open duration of epileptic attack before 45 days. In this case we try to explain that the wrong intervention in epileptic attack and delaying treatment of infections of human bites can be resulted with limb missing.Öğe Investigation of mechanical strength of teicoplanin and ciprofloxacin impregnated bone cement on Day 1 and Day 15(TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2014) Golge, Umut Hatay; Oztemur, Zekeriya; Parlak, Mesut; Tezeren, Gunduz; Ozturk, Hayati; Bulut, Okay…Öğe Long segment instrumentation of thoracolumbar burst fracture: Fusion versus nonfusion(IOS PRESS, 2009) Tezeren, Gunduz; Bulut, Okay; Tukenmez, Mehmet; Ozturk, Hayati; Oztemur, Zekeriya; Ozturk, AliObjective: The treatment of thoracolumbar burst fracture is a controversial issue. Although spinal fusion has been touchstone of spinal fixation, nonfusion technique have become raising its popularity recently. Some studies suggested that nonfusion had several advantages over fusion. The aim of this prospective study was to compare long segment posterior instrumentation with fusion versus long-segment posterior instrumentation without fusion. Methods: For this purpose, 42 consecutive patients were assigned to two groups. Group 1 included 21 patients treated by long segment instrumentation with fusion (WF), whereas Group 2 included 21 patients treated by long segment instrumentation without fusion (WOF). Long segment instrumentation was hook fixation (claw hooks attached to second upper vertebra and infralaminar hooks attached to first upper vertebra) above and pedicle fixation (pedicle screws attached to first and second lower vertebrae) below the fractured vertebra. Results: Measurements of local kyphosis, sagittal index and anterior vertebral height compression showed that both group had similar outcome at final follow-up. Moreover, there was no difference between the two groups according to low back outcome score. Also, implant failure rate (4.7%) was quite low in both groups. However, WF group had prolonged operative time, increased blood loss and donor site morbidity. Conclusions: Radiological and clinical parameters demonstrated that spinal fusion is not necessary in long segment posterior instrumentation for the management of thoracolumbar burst fractures.Öğe The long-term effects of extracorporeal shock waves on the epiphysis of the adolescent rat(SPRINGER JAPAN KK, 2013) Oztemur, Zekeriya; Ozturk, Hayati; Ozyurek, Selahattin; Kaloglu, Celal; Golge, Umut Hatay; Bulut, OkayExtracorporeal shock waves (ESW) have been successfully used to treat musculoskeletal injuries, tendinopathy, and plantar fasciitis. Different side effects of high-energy ESWT on bones, tendons, nerves, epiphysis, and cartilage have been discussed. Although the effects of ESW on the epiphysis in animal models have been described, no studies have investigated the long-term effect of ESW on the immature epiphysis in an animal model. The purpose of this study was to investigate the long-term effects of ESW on the immature epiphysis in rats. Sixteen 4-week old Wistar albino rats, average weight 116.3 grams (109.6-120.2 g) were used for these experiments. The rats were randomly divided into two groups, the ESW 1500 pulses (ESW1500p) group (n = 8) and the ESW 3000 pulses (ESW3000p) group (n = 8). In the ESW1500p group, 1500 pulses, at 4 bar, of 1-Hz shockwaves were applied, once, to the left knees of the rats. In the ESW3000p group, 3000 pulses, at 4 bar, of 1-Hz shockwaves were applied, once, to the left knees of the rats. The right knees (n = 16) of the rats in the two groups were used as the controls. The animals were sacrificed after an 8-month follow-up period. Femoral epiphyses were assessed by use of histology. The femoral length (FL), tibial length (TL), and femoral supracondylar medio-lateral width (MLW) were measured. There was no statistically significant difference between FL, TL, and MLW for the three groups (P > 0.05). The average histological scores were 8.8 (7-10), 17.8 (15-22), and 2.7 (0-4) in the ESW1500p, the ESW3000p groups, and the controls, respectively. The average histological score for the ESW3000p group was significantly higher than those for the ESW1500p group and the controls (P < 0.001). The average histological score for the ESW1500p group was significantly higher than that for the controls (P < 0.001). The histological findings of this study indicate that ESW increased the cellularity and basophilia of the extracellular matrix (ECM) in the adolescent rat epiphysis and there were no negative effects on extremity measurements in the long term.Öğe Neutrophil to Lymphocyte Ratio May Be a Diagnostic Marker for Prosthetic Joint Infection(DERMAN MEDICAL PUBL, 2016) Golge, Umut Hatay; Kaymaz, Burak; Pazarci, Ozhan; Kilinc, Seyran; Oztemur, Zekeriya; Bulut, OkayAim: Total knee arthroplasty (TKA) is an effective and successful procedure but the outcome may occasionally be compromised by complications such as periprosthetic joint infection (PJI). Blood neutrophil to lymphocyte ratio (NLR) is a simple marker of subclinical inflammation that can be easily obtained from the differential White Blood Cell count. This study aims to to analyze the predictive ability of NLR for the diagnosis of PJI. Material and Method: Patients who were diagnosed as grade 4 gonartrosis and operated for total knee arthroplasty between years 2007-2014 were evaluated. Thirty patients with PJI were included in the study as Group I and hematological tests including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), white blood cell count (WBC) and neutrophil to lymphocyte ratio (NLR) of the patients were evaluated retrospectively. Preoperative and postoperative 6th month NLR values of the patients were compared. Also 103 age matched patients operated for total knee arthroplasty with no sign of infection were included in the study as controls (Group II). Patients in Group I and Group II were also compared in terms of NLR. Results: Thirty patients (17 female, 13 male) were present in Group I (patients with PJI and treated with two staged revision surgery) and 103 patients (94 female, 9 male) were present in Group II (patients operated for total knee arthroplasty and had no sign of infection during the follow up period). NLR has been found to decrease from 3.2+/-0.7 to 2.2+/-0.5 when compared between the preoperative and postoperative 6th month period (p=< 0,001). NLR has been found to be 2.1+/-0.7 in Group II and 3.2+/-0.7 in Group I at preoperative period. (p=< 0,001). The value of 2.45 was found to be cut-off point for infection. Discussion: NLR can be used as marker for PJI together with the other markers as ESR and CRP to increase the accuracy of the diagnosis.Öğe Pigmented villonodular synovitis managed by Yttrium 90 after debulking surgery(SAUDI MED J, 2008) Ozturk, Hayati; Bulut, Okay; Oztemur, Zekeriya; Bulut, Sema…
