    Birmingham hip resurfacing: Short term results
    (2021) Bingol, Izzet; Balaban, Mehtap; Ugurlu, Mahmut
    Aim: Hip joint replacement provides a dramatic improvement in the quality of life of patients with hip arthrosis but this effect has not been fully achieved in young patients because of early failure with total hip arthroplasty with high activity level. A bone mass protective procedure such as hip resurfacing arthroplasty might be advantageous in young patients. Many options for hip resurfacing prosthesis are available. One of the most used is the Birmingham hip resurfacing prosthesis. The purpose of this investigation compared retrospectively the functional, clinical and radiological outcomes of patients who underwent Birmingham hip resurfacing arthroplasty by a single surgeon for various hip arthrosis.Materials and Methods: Twenty-six hips of 22 patients (12 male, 10 female) were evaluated by using Harris hip score preoperatively and postoperatively. Anteroposterior, lateral and cross-table lateral radiographs of the pelvis and hips were evaluated with respect to component position, migration, and radiolucency postoperatively and at every follow up. Acetabular inclination and anteversion angle, implant-femoral shaft angle, varus and valgus positon, pseudotumor formation around the hip were evaluated by radiologist. Blood samples of patients were taken at last follow ups and evaluated for cobalt and chromium levels by using an inductively-coupled plasma mass spectrometer. Results: Postoperative Harris hip scorewas found to be significantly higher than preoperative Harris hip score. Correlation between chromium ion and size of femoral component, cobalt ion and cup anteversion angle had inverse relationship. There was significant correlation between cobalt ion and gender; females had higher levels of cobalt ion than males.Conclusion: In order to avoid ion load in Birmingham hip resurfacing, caution in selection of patients, avoidance of the use of small components, and attention to the surgical technique to ensure proper placement of the component angles are crucial.

    The burden of scoliosis: a nationwide database study on demographics, incidence, and surgical rates
    (Springer, 2024) Saglam, Yavuz; Bingol, Izzet; Yasar, Niyazi Erdem; Dumlupinar, Ebru; Ata, Naim; Ulgu, M. Mahir; Birinci, Suayip
    Introduction Scoliosis is characterized as a three-dimensional deformity of the spine, affected by variety of factors, including biological, mechanical, hormonal, and genetics.Methods Our study's primary objective was to delineate the demographics, incidence, and prevalence of scoliosis from a nationwide perspective, analyze the surgical intervention rates, with the aim of offering more insightful guidance to orthopedic physicians. This nationwide cohort study was conducted from digital database for healthcare information management. Relevant population data, for children under 18 years old, was extracted from the official government census within the period of January 2015 to December 2022. Utilizing diagnostic code of M41 [Scoliosis] was used to define the patient pool from ICD-10. Demographic variables, type of operations (posterior only, anterior only, or combined), and complications were documented. Incidence and prevalence values were calculated using population figures and case numbers.Result There were 276,521 patients with an average incidence of 129 per 100,000. Frequency of females was 1.45 times greater than that of males (p < 0.001). A total of 10,417 surgeries were performed in 10,311 patients during the inspection period (3.8% of all cases). Posterior fusion was by far the most common surgical approach (n = 10.111; 97%) followed by anterior fusion (n = 200; 1,9%).Conclusions Our findings reveal a significant increase in the average incidence of scoliosis diagnosis, rising from 107 per 100,000 individuals in 2015 to 161 per 100,000 in 2022. Scoliosis now impacts an estimated 1.2% of children and adolescents in Turkey. The risk is 1.45 times higher in females than in males.

    Epidemiology and demographics of pediatric proximal femur fractures in Türkiye: results from a government-based health registry
    (Lippincott Williams & Wilkins, 2024) Soylemez, Mehmet Salih; Bingol, Izzet; Yasar, Niyazi Erdem; Dumlupinar, Ebru; Ayvali, Mustafa Okan; Ata, Naim; Ulgu, M. Mahir
    We evaluate the epidemiology and incidence of pediatric proximal femur fractures, treatment trends among different hospital levels, and complication rates among different treatment modalities by examining a national health registry in T & uuml;rkiye. The health records of individuals aged <= 16 years admitted to public, private, and university hospitals were collected via the e-health database of the Turkish Ministry of Health. A total of 2388 children treated for proximal femur fractures from 2016 to 2021 with at least 2 years of follow-up were included in the study. While 2033 (85.1%) patients were treated with closed reduction and spica casts, 355 (14.8%) were operated on. Mean age was 8.603 +/- 5.11 years. Male incidence was 2-fold greater compared to female patients (36.4% female and 63.6% male patients; P < 0.001). The frequency of cases was significantly increased in the age groups of 3-4 and 13-16 years. Comorbidities causing limited ambulation were detected in 6.5% of all cases, and 163 (8.0%) patients in the conservative group and 98 (27.6%) patients in the surgery group had at least one complication. The incidence was 0.45 per 100 000 children aged <= 16 years. This study reports the largest patient cohort to date, providing evidence on the epidemiology and incidence of pediatric proximal femur fractures using health registry data. We have found that the most common treatment modality for proximal femur fractures is closed reduction with spica casts. The rate of avascular necrosis is similar among patients treated surgically and those treated conservatively.
