Item type:Publication, Correlation of low-energy vertebral fracture, clinical risk factors and bone densitometry in postmenopausal women(Faculty of Medicine, Ss. Cyril and Methodius University in Skopje, 2020) ;Popovska, Danica; ;Karevski, LjupchoAim: To analyze prevalent vertebral fractures (VF), clinical risk factors and dual energy x-ray absorbtiometry (DXA) results in postmenopausal women. Material and method: In a cross-sectional study we included 120 postmenopausal women (61 with VF, 59 without VF). VFs were diagnosed in lateral thoracolumbar X-rays and classified according to the semiquantitative method of Genant. In all patients, DXA was performed for lumbar spine, hip and distal forearm. Results: The mean age of patients was 68.7 years in VF group and 61 in non-fracture group (p<0.05). Patients in VF group had significantly higher reporting of back pain, height loss and previous low-energy fracture; were significantly shorter and had lower body weight than patients in nonfracture group. Bone mineral density (BMD) was significantly lower for all points of measurement in VF group. In VF group, 57.4% of patients had lumbar T-score<=-2.5SD, 34.4% had osteopenia and 8.2% T-score>=-1SD. Eighty percentage had Tscore<=-2.5 in at least one point of measurement. BMD in all points of measurement correlated with number and grade of VF (p<0.05). Conclusion: Age, previous low energy fracture and BMD in at least two measurement points should be factored when assessing low-energy fracture risk and need for treatment. Low-energy VF should be actively searched for in women with advanced age, history of back pain and self-reported height loss. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Influence of vancomycin and meropenem loading on compressive strength of polymethyl methacrylate bone cement(Институт за јавно здравје на Република Македонија = Institute of public health of Republic of Macedonia, Co-publisher Scientific foundation Spiroski, 2025) ;Popovska, Danica; ; ;Shabani, IlirThe rise of antibiotic resistance of certain bacteria to commonly used agents in antibiotic- loaded polymethyl methacrylate (PMMA) bone cement has led to the search for new antibiotic agents. A potential problem in introducing new antibiotics into the PMMA mixture is disruption of the mechanical properties of bone cement, which is intended for mechanical fixation of joint implants. The aim of this study was to test compressive strength of bone cement loaded with vancomycin, meropenem or their combination. Materials and methods: Five groups of samples (PMMA, PMMA+2.5%w/w vancomycin, PMMA+2.5%w/w meropenem, PMMA+1.25%w/w vancomycin and 1.25%w/w meropenem and PMMA+2.5%w/w vancomycin and 2.5%w/w meropenem) were prepared and tested for compressive strength according to specifications of the ISO5833:2002 international standard. Results: All tested groups had compressive strength significantly above the minimum value of 70 MPa set by the standard (87.9 – 98.6MPa, p<.0001). All groups of antibiotic-loaded bone cement had significantly lower compressive strength than PMMA. Conclusion: All tested groups met the basic compressive strength criteria for clinical use in arthroplasty procedures. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Factors Affecting In-Hospital Mortality in Patients with Hip Fracture(Albanian Society for Trauma and Emergency Surgery, 2022-01-20) ;Popovska, Danica; ; ;Dalipi, RezeartTodorova, TeodoraBackground. The prevalence of hip fractures is steadily increasing, as the population ages. These fractures are associated with significant morbidity and mortality. Most of these fractures are treated surgically. Factors related to surgical intervention can play a significant role in the outcome. This study examines the association of in-hospital mortality with the timing of surgery, sex, and age of patients treated surgically due to a hip fracture at Clinical Hospital Shtip in a 2-year long period. Material and Methods. A total of 348 patients admitted with a diagnosis of hip fracture who were treated surgically were identified. Data about sex and age were collected. The outcome was assessed for groups treated within 24, 48, 72, and more than 72 hours after admission. Descriptive statistical methods, chi-square test, t-test for independent samples, and odds - ratio with 95% confidence interval (CI) were used in statistical analysis. Results. The delay of surgical treatment beyond 24 hours did not increase the risk of death (OR=0.65, 95%CI=0.23-1.73). Delays beyond 48h and 72h increased the risk of death progressively (OR=1.17, 95%CI=0.50-2.75, and OR=1.65, 95%CI=0.69-3.95 respectively). Mortality was significantly higher in the 76-85-years age group. Conclusions. Association between surgical delay and in-hospital mortality in hip fracture patients is disputed. Confounding factors such as age, sex, comorbidities, and type of treatment determine the outcome. Patients with hip fractures, without any additional disease, should be operated on as soon as possible after admission to the hospital. Delay beyond 48 hours may increase the risk for in-hospital mortality. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Efficacy of Alendronate in Preventing Periprosthetic Bone Loss after Implantation of a Primary Hip Endoprosthesis(Scientific Foundation SPIROSKI, 2022-07) ;Shabani, Ilir; ; ; BACKGROUND: Total hip arthroplasty (THA) is now the gold standard for the surgical treatment of coxarthrosis. The appearance of bone loss after implantation of the hip endoprosthesis over time reduces the primary stability of the implant and leads to progressive loosening of the implant or periprosthetic fracture, which are considered to be the most common causes of hip revision. AIM: The aim of this study is to evaluate the value of alendronate application in reducing periprosthetic osteolysis reduction after implantation of total cementless hip endoprosthesis. METHODS: The study analyzed 50 patients operated on with implantation of a cementless THA. The first group of 25 patients received oral alendronate, calcium, and Vitamin D3 postoperatively. The second group of 25 patients was examined and followed postoperatively without any therapy. Patients were examined by RTG and dual energy X-ray absorption (DXA) methods at 6, 12, and 18 months. RESULTS: The study showed a difference in the values of bone mineral density and bone mineral content in the interval of 6,12, and 18 months, using the DXA method. CONCLUSION: Alendronate therapy after total hip implantation reduces periprosthetic bone loss, maintains bone mineralization, and strengthens the implant. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, THE IMPORTANCE OF FOLLOWING THE ORIGINAL PONSETI METHOD IN TREATMENT OF CLUBFOOT: THE IOWA EXPERIENCE(Македонско друштво на ортопеди и трауматолози = Macedonian Association of Orthopedics and Traumatology, 2022); ;Bogojevski, Ljubomir; ; Dr. Ignacio Vives Ponseti, an American orthopaedic surgeon with Spanish origin, was born on June the 3rd, 1914 and died at the age 95 in Iowa, USA, on October 18th 2009. He was a brilliant pediatric orhopaedic surgeon, best known for his method of nonoperative treatment of clubfoot, that has become a gold standard of clubfoot treatment. His iconic paper on clubfoot management (1963) is one of the few manuscripts in orthopaedic literature which has radically changed the practice as we know it now. The Ponseti method is easy to learn but, unfortunately easy to modify because modification negatively affects the treatment outcome. That emphasizes the need to learn and follow the exact steps explained by Dr. Ponseti. The first author of this article had the opportunity to learn this method in the place where it all started, guided by Dr. Jose Morcuende, the successor of Dr. Ponseti who continues his legacy in the brightest way possible. After return from the stay at Iowa Stead Family Children’s Hospital 16 patients and 23 feet were treated with best possible adherence to the Ponseti Method. We began using the original Ponseti method in October 2019. Since then, 16 patients, 7 bilateral, 9 unilateral (23 feet in total) have been treated and evaluated. We strove as much as possible to reproduce Ponseti’s strict casting protocol faithfully, as explained in the paper. Usually, for correction of the first three components 4 to 10 casts are necessary, changed on a weekly basis. Equinus is the last deformity to be corrected. In order to avoid prolonged casting and concomitant appearance of rocker bottom deformity, the correction of equinus is facilitated by a simple operative procedure in local anesthesia. Sixty five percent of the patients had good results, 31% had acceptable results, in one patient there was poor result. Compared to the original Ponseti paper from 1963, there is not any significant difference in the results, except the bigger percent of poor results that involves only one patient in our series. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Conoccurence of extraskeletal osteosarcoma and undiagnosed Paget disease in a 49-year-old female(Oxford University Press (OUP), 2025-01); ;Todorova, Teodora ;Popovska, Danica; Angelovska, TamaraExtraskeletal osteosarcoma (ESOS) represents a rare soft tissue entity, accounting for ⁓1% of all soft tissue malignancies. It is generally considered to have an even worse prognosis than bone osteosarcoma, therefore detailed investigations and proper treatment are required. ESOSs arising in the subcutaneous tissue are even rarer than the ones positioned in deep tissues, and they are considered to have far better outcomes. We present a case of a 49-year-old patient diagnosed with subcutaneous ESOS and Paget disease of the bone, which is not typical for the patient's age, considering that Paget disease of the bone tends to affect a population above 50 years. The coexistence of these two entities in a single patient and all their features make this case unique, and to the best of our knowledge, this is the first case reported. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, PATIENT SATISFACTION WITH KNEE ARTHROSCOPY UNDER LOCAL ANESTHESIA AND SEDATION(Department of Anaesthesia and Reanimation, Faculty of Medicine, Ss. Cyril and Methodius University in Skopje, R.N. Macedonia, 2024-12-21) ;Andonovski, Аlan; ; Popovska, DanicaIntroduction: Knee arthroscopy can be performed under general, regional (spinal or epidural) or local anesthesia with different patients’ satisfaction after surgery. Purpose: The aim of our study was to evaluate the level of satisfaction in patients after knee arthroscopy under local anesthesia. Patients and methods: The study included 52 patients where knee arthroscopy under local anesthesia was performed at the University Clinic for Orthopedic Surgery in Skopje, North Macedonia in the period from February 2021 to February 2022. The study did not include patients with allergy to the used drugs, infection at the portal sites of injection, any previous surgery to the knee, patients with chronic extensive synovitis or gross deformity of the knee (severe varus or valgus knee), as well as those with psychological problems, severe systemic disease, consumption of analgesics or non-steroidal anti-inflammatory drugs within 24 h of surgery, bleeding diathesis or coagulopathy. Evaluation of patients’ satisfaction after surgery was done one to three months later by determining the level of satisfaction, pain during surgery, anesthesia-related postoperative complications and preference of this anesthetic technique in the future. Results: The majority of patients were either very satisfied (84.6%) or satisfied (9.6%) with local anesthesia for knee arthroscopy. Only 1.9% of them were not satisfied at all. Most of the patients reported no pain (80.8%) or mild pain (11.5%) during knee arthroscopy under local anesthesia. Only 1.9% of patients complained of strong or very strong pain during arthroscopy. Of all patients, 51 (98%) had no anesthesia-related problems after surgery except one patient who had redness, pain, swelling and blisters formation on the portal where local anesthetic and adrenaline were previously injected. Most of the patients (96%) reported that they would choose local anesthesia for knee arthroscopy again. Conclusion: Our study showed that most patients had no pain, were very satisfied and would choose local anesthesia for knee arthroscopy again. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, MRI EVALUATION OF BIOLOGICALLY ENHANCED ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION(Faculty of Medicine, Ss. Cyril and Methodius University in Skopje, 2024-04); ; ; Popovska, DanicaPlatelet-rich plasma (PRP) and anterior cruciate ligament (ACL) residual remnant preservation are used today as biologic therapies aimed at stimulating graft healing process after ACL reconstruction, but their synergism has not been established yet. The aim of our study was to investigate the combined influence of PRP and ACL remnant preservation on graft healing after ACL reconstruction and evaluate the results with MRI. Material and methods: The study included 52 patients (45 men and 7 women, mean age 28) divided into 2 groups: group I (control group)-28 patients in whom after the removal of ACL residual bundle, a standard single bundle ACL reconstruction was made, and group II (examined group)-24 patients in whom remnant preserving ACL reconstruction with addition of PRP was performed. The results were assessed 6 months after surgery by MRI evaluation of the graft healing process. Results: Patients in the examined group had more frequently a light hyperintense signal of the intra-articular part of the graft (75% vs. 35.7%, p=0.0046) and absence of synovial fluid at tunnel-graft interface (45.8% vs. 21.4%, p=0.06), average 0.98 cm 2 less surface of bone edema around the graft (p=0.009) than those from the control group. Conclusion: Combined use of PRP and ACL remnant preservation has a positive influence on graft healing after ACL reconstruction leading to faster ligamentization and osteoligamentous integration of the graft.
