RESUMO

There is still limited understanding of the microstructural reasons for the higher susceptibility to fractures in individuals with type 2 diabetes mellitus (T2DM). In this study, we examined bone mineralization, osteocyte lacunar parameters, and microhardness of the femoral neck trabeculae in 18 individuals with T2DM who sustained low-energy fracture (T2DMFx: 78 ± 7 years, 15 women and 3 men) and 20 controls (74 ± 7 years, 16 women and 4 men). Femoral necks of the T2DMFx subjects were obtained at a tertiary orthopedic hospital, while those of the controls were collected at autopsy. T2DMFx individuals had lower trabecular microhardness (P = .023) and mineralization heterogeneity (P = .001), and a tendency to a lower bone area with mineralization above 95th percentile (P = .058) than the controls. There were no significant intergroup differences in the numbers of osteocyte lacunae per bone area, mineralized lacunae per bone area, and total lacunae per bone area (each P > .05). After dividing the T2DMFx group based on the presence of vascular complications (VD) to T2DMFxVD (VD present) and T2DMFxNVD (VD absent), we observed that microhardness was particularly reduced in the T2DMFxVD group (vs. control group, P = .02), while mineralization heterogeneity was significantly reduced in both T2DMFx subgroups (T2DMFxNVD vs. control, P = .002; T2DMFxVD vs. control, P = .038). The observed changes in mineralization and microhardness may contribute to the increased hip fracture susceptibility in individuals with T2DM.

RESUMO

Background: The external fixation (EF) Ilizarov method, shown to offer efficacy and relative safety, has unique biomechanical properties. Intramedullary nail fixation (IMN) is an advantageous alternative, offering biomechanical stability and a minimally invasive procedure. The aim of this study was to assess outcomes in patients undergoing tibia fracture fixation, comparing the Ilizarov EF and IMN methods in an early phase of IMN implementation in Serbia. Methods: This was a retrospective study including patients with radiologically confirmed closed and open (Gustilo and Anderson type I) tibial diaphysis fractures treated at the Institute for Orthopedic Surgery "Banjica'' from January 2013 to June 2017. The following demographic and clinical data were retrieved: age, sex, chronic disease diagnoses, length of hospital stay, surgical wait times, surgery length, type of anesthesia used, fracture, prophylaxis, mechanism of injury, postsurgical complications, time to recovery, and pain reduction. Pain intensity was measured by the Visual Analog Scale (VAS), a self-reported scale ranging from 0 to 100 mm. Results: A total of 58 IMN patients were compared to 74 patients who underwent Ilizarov EF. Study groups differed in time to recovery (p < 0.001), length of hospitalization (p = 0.007), pain intensity at the fracture site (p < 0.001), and frequency of general anesthesia in favor of intramedullary fixation (p < 0.001). A shorter surgery time (p < 0.001) and less antibiotic use (p < 0.001) were observed when EF was used. Additionally, we identified that the intramedullary fixation was a significant predictor of pain intensity. Conclusions: The IMN method offers faster recovery and reduced pain intensity in comparison to EF, while the length of surgery predicted the occurrence of any complication.

RESUMO

OBJECTIVE: To examine the presence of certain shapes of the first metatarsal-cuneiform joint (MTC) joint in feet with hallux valgus (HV) deformity. To determine whether the anatomical orientation of this joint affects the size of the hallux valgus angle (HVA) and the first intermetatarsal angle (IMA) and whether it contributes to the dynamics of the developmental course of HV deformity. METHODS: The shape of the first MTC joint was determined on a sample of 315 feet with HV deformity. The influence of the shape of this joint on the values of HVA and IMA was explored. The relation between the position of the tibial sesamoid and the size of HVA and IMA as well as the dynamics of the development of this deformity depending on the shape of the first MTC joint, was examined. RESULTS: The oblique shape of the first MTC joint was found in 165 (52.4%) feet, the transverse in 145 (46%), and the convex shape was registered in five feet (1.6%). In the oblique shape of this joint, a moderate and severe degree of HV deformity is predominant, while in the transverse shape a mild degree dominates. A statistically significant dependence of HVA on the shape of the first MTC joint was found (Sig. = 0.010), while the dependence of IMA did not show statistical significance (Sig. = 0.105). HVA values follow the position of the tibial sesamoid in both shapes of the MTC joint while the size of the IMA in the transverse shape does not follow the change of the position of this sesamoid. CONCLUSION: The oblique shape of the first MTC joint is associated with the more severe form of HV deformity and its faster developmental course. In the analyzed sample, it was shown that HVA is higher in the oblique shape of the MTC joint and significantly depends on the anatomical orientation of this joint. Furthermore, IMA has a higher value in the oblique shape compared to transverse but this dependence is not statistically significant. The analysis showed that the oblique shape of the first MTC joint contributes to the development of HV deformity.

RESUMO

The cementless Corail stem is one of the most frequently implanted stems and has undergone several design changes. Currently in use is the third generation, named Corail AMT. Until now, only one third-generation Corail stem neck fracture has been described in 2020. In our paper, we present an almost identical complication with an additional analysis of the fracture using a scanning electron microscope. The revision surgery consisted of changing the broken implant with a Corail revision stem, along with replacing the polyethylene liner and the femoral head with new one, after which the patient achieved a full recovery. According to the available literature, this is the second case of this extremely rare complication.

RESUMO

BACKGROUND: Perthes disease is a juvenile form of osteonecrosis of the femoral head that affects children under the age of 15. One hundred years after its discovery, some light has been shed on its etiology and the biological factors relevant to its etiology and disease severity. METHODS: The aim of this study was to summarize the literature findings on the biological factors relevant to the pathogenesis of Perthes disease, their diagnostic and clinical significance, and their therapeutic potential. A special focus on candidate genes as susceptibility factors and factors relevant to clinical severity was made, where studies reporting clinical or preclinical results were considered as the inclusion criteria. PubMed databases were searched by two independent researchers. Sixty-eight articles were included in this review. Results on the factors relevant to vascular involvement and inflammatory molecules indicated as factors that contribute to impaired bone remodeling have been summarized. Moreover, several candidate genes relevant to an active phase of the disease have been suggested as possible biological therapeutic targets. CONCLUSIONS: Delineation of molecular biomarkers that underlie the pathophysiological process of Perthes disease can allow for the provision of earlier and more accurate diagnoses of the disease and more precise follow-ups and treatment in the early phases of the disease.

RESUMO

Individuals with diabetes mellitus type 2 (T2DM) have an increased risk of hip fracture, especially if vascular complications are present. However, microstructural origins of increased bone fragility in T2DM are still controversial. DXA measurement of the contralateral hip and three-dimensional microCT analyses of femoral neck trabecular microarchitecture were performed in 32 individuals (26 women and 6 men, 78 ± 7 years). The specimens were divided to two groups: T2DM individuals with hip fracture (DMFx, n = 18) and healthy controls (CTL, n = 14). DMFx group consisted of individuals with vascular complications (DMFx_VD, n = 8) and those without vascular complications (DMFx_NVD, n = 10). T-score was significantly lower in DMFx_VD and DMFx_NVD than in controls (p < 0.001). BV/TV, Tb.N, Tb.Sp, SMI, and FD varied among DMFx_NVD, DMFx_VD, and CTL groups (p = 0.023, p = 0.004, p = 0.008, p = 0.001, p = 0.007, respectively). Specifically, BV/TV of DMFx_VD was significantly lower than that of DMFx_NVD group (p = 0.020); DMFx_NVD group had higher Tb.N and lower Tb.Sp compared with DMFx_VD (p = 0.006, p = 0.012, respectively) and CTL (p = 0.026, p = 0.035, respectively). DMFx group and healthy controls showed similar BV/TV, Tb.Th, Tb.N, Tb.Sp, Conn.D, DA, and FD (p = 0.771, p = 0.503, p = 0.285, p = 0.266, p = 0.208, p = 0.235, p = 0.688, respectively), while SMI was significantly higher in controls (p = 0.005). Two distinct phenotypes of bone fragility were identified in T2DM patients: patients with vascular complications showed impaired trabecular microarchitecture, whereas bone fragility in the group without vascular complications was independent on trabecular microarchitecture pattern. Such heterogeneity among T2DM patients may explain contradicting literature data and may set a basis for further studies to evaluate fracture risk related to T2DM.

RESUMO

To examine the influence of the configuration of the first and second metatarsal (MT) bones on the development of hallux valgus deformity. To determine the extent to which the difference in the lengths of the first and second MT bones, measured distal to the Maestro line, contribute to the severity of the hallux valgus (HV) deformity defined by the size of the hallux valgus angle (HVA) and inter-metatarsal angle (IMA). On a sample of 319 feet with HV deformity the difference of measured lengths R = d (I MT) - d (II MT) was calculated The influence of differences (R) on the values of IMA and HVA as well as on the severity of deformities according to the formed groups was investigated. The influence of age on the development of deformities was examined separately as well as in conjunction with the determined difference in lengths. In 203 feet or 63.7%, a shorter MT bone was measured, while in 80 feet or 25.1% the first MT bone was longer than second ones and only in 36 feet or 11.3% there is no difference in the length of the 1st and 2ndMT bones distal to the Maestro line. A statistically significant correlation was found between the difference between the measured lengths of 1st and 2nd MT bones and IMA, while this correlation with HVA was not statistically significant. There is no statistically significant correlation or the effect of the difference in measured lengths (R) on the severity of hallux valgus deformity classified into three groups. A statistically significant correlation and impact of the age on the intensity of the deformity are established. A shorter 1st MT bone in correlation to the 2nd MT bone is accompanied by an increase in IMA and this correlation and impact are statistically significant. It was not established that there was a statistically significant influence of the length of the first and second metatarsal bone measured distal from Maestro line upon the values of HVA and severity of HV deformity. Age significantly contributes to the severity of the deformity.

RESUMO

INTRODUCTION: Split tendon transfer of tibialis posterior (SPOTT) is a treatment option for the hindfoot varus deformity in patients with cerebral palsy (CP). The purpose of this study was to present the long-term results of the newly modified SPOTT procedure developed by our senior author and compare it with the standard SPOTT technique in equinovarus foot deformity due to CP. METHOD: Our retrospective cohort study included patients with spastic foot deformity due to CP treated with the standard or modified SPOTT technique. Patients' age at the time of the surgery was ≥ five years with follow-up period of at least four years. Surgical outcomes were evaluated using Kling's criteria during the patient's last follow-up visit. RESULTS: The analysis included 124 patients (146 feet), where 105 feet were treated by the standard SPOTT technique and 41 feet by the modified SPOTT technique. Patients' median age at the time of the surgery was 11 years. Patients were followed-up for a median period of eight years during which the modified SPOTT technique showed significantly better surgical outcomes compared with the standard group (excellent/good results in 38 feet, 92.7%, vs. 79 feet, 75.2%, p = 0.02). Two groups of patients did not significantly differ in GMFCS level, age at the time of the surgery, or patient gender. There was similar distribution in CP patterns in the standard and modified groups; spastic hemiplegia was the most prevalent form, followed by spastic diplegia and spastic paraplegia. Overall, better surgical success was achieved in patients with GMFCS levels I-III (100%, 94.8%, and 69.8%, respectively). SPOTT procedure failure was frequently noticed in patients with GMFCS level IV (90.9%). CONCLUSION: The modified SPOTT procedure demonstrated efficiency and safety in patients with equinovarus foot deformity due to CP during the long-term follow-up. Compared with the standard procedure, the newly modified SPOTT technique showed significantly better surgical outcome, irrespective of the patients' gender, age, initial GMFCS level, and CP type.

RESUMO

The purpose of this work is to develop a new model estimate of the fatigue life of a hip prosthesis due to aseptic loosening as a multifactorial phenomenon. The formula developed here is a three-parameter model based on Basquin's law for fatigue, eccentric compression formula for the compressive stress and torsion in the prosthesis due to the horizontal components of the contact force. With our model, we can accurately predict the durability of a hip prosthesis due to the following four parameters: body weight, femoral offset, duration, and intensity of daily physical activities of a patient. The agreement of the prediction with the real life of the prosthesis, observed on 15 patients, is found to be adequate. Based on the formula derived for a particular implant, there was a high degree of concurrence between the model-predicted and actual values of aseptic loosening (durability) proved by the Mann-Whitney U test. By virtue of the validated model, it is possible to predict, quantitatively, the influence of various factors on the hip life. For example, we can conclude that a 10% decrease of a patient's body mass, with all other conditions being the same, causes 5% increase of the hip fatigue life.

RESUMO

BACKGROUND: Osteoarthritis (OA) is a chronic degenerative joint disease and is considered to be the fourth leading cause of disability and the second cause of inability to work in men. Recently, adipose-derived mesenchymal stem cells (AD-MSCs) came into focus for regenerative medicine as a promising tool for the treatment of OA. The administration of stem cells into impaired joints results in pain relief and improves quality of life, accompanied by restoration of hyaline articular cartilage. METHODS: In the present study, nine patients (including two patients with bilateral symptoms) diagnosed with osteoarthritis (International Knee Documentation grade B in 5 and grade D in six knees) were treated using a single injection of AD-MSCs at a concentration of 0.5-1.0 × 107 cells and were followed up for 18 months. During follow-up, all the cases were evaluated clinically by Knee Society score (KSS), Hospital for Special Surgery knee score (HSS-KS), Tegner-Lysholm (T-L) score and visual analogue scale (VAS) of pain, as well as by plain radiography and by magnetic resonance imaging visualization with 2D Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score assessment. RESULTS: Significant improvement of all four clinical scores was observed within the first 6 months (KSS for 41.4 points, HSS-KS for 33.9 points, T-L score for 44.8 points, VAS of pain from 54.5 to 9.3) and improvement persisted throughout the rest of the follow-up. MOCART score showed significant cartilage restoration (from 43 ± 7.2 to 63 ± 17.1), whereas radiography showed neither improvement, nor further joint degeneration. CONCLUSIONS: The results obtained in the present study provide good basis for prospective randomized controlled clinical trials with respect to the use of AD-MSCs in the treatment of osteoarthritis.

RESUMO

UNLABELLED: Perthes disease is one of the most common forms of pediatric femoral head osteonecrosis with an unknown etiology. Coagulation factors were the first genetic factors suspected to have a role in the pathogenesis of this disease, but studies showed inconsistent results. It is described that inflammation is present during early stages of Perthes disease, but its genetic aspect has not been studied extensively. Little is known regarding the status of apoptotic factors during the repair process that leads to the occurrence of hip deformity in patients. Therefore, the aim of this study was to analyze major mediators involved in coagulation, inflammation, and apoptotic processes as possible causative factors of Perthes disease. The study cohort consisted of 37 patients. Gene variants of TNF-α, FV, FII, and MTHFR genes were determined by PCR-RFLP, while IL-3 and PAI-1 were genotyped by direct sequencing. The expression level of Bax, Bcl-2, Bcl2L12, Fas and FasL was analyzed by quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) technique. Our results showed a significantly increased level of expression of pro-apoptotic factor Bax along with significantly higher Bax/Bcl-2 ratio in the patient group. CONCLUSION: The results presented indicate that apoptosis could be one of the factors contributing to the lack of balanced bone remodeling process in Perthes patients.

RESUMO

INTRODUCTION: Perthes disease is idiopathic avascular osteonecrosis of the hip in children, with unknown etiology. Inflammation is present during development of Perthes disease and it is known that this process influences bone remodeling. OBJECTIVE: Since genetic studies related to inflammation have not been performed in Perthes disease so far, the aim of this study was to analyze the association of frequencies of genetic variants of immune response genes, toll-like receptor 4 (TLR4) and interleukin-6 (IL-6), with this disease. METHODS: The study cohort consisted of 37 patients with Perthes disease and 50 healthy controls. Polymorphisms of well described inflammatory mediators: TLR4 (Asp299Gly, Thr39911e) and 11-6 (G-174C, G-597A) were determined by polymerase chain reaction restriction fragment length polymorphism method. Results IL-6 G-174C and G-597A polymorphisms were in complete linkage disequilibrium. A statistically significant increase of heterozygote subjects for IL-6 G-174C/G-597A was found in controls in comparison to Perthes patient group (p = 0.047, OR = 2.49, 95% CI = 1.00-6.21). Also, the patient group for IL-6 G-174C/G-597A polymorphisms was not in Hardy-Weinberg equilibrium. No statistically significant differences were found between patient and control groups for TLR4 analyzed polymorphisms. A stratified analysis by the age at disease onset also did not reveal any significant difference for all analyzed polymorphisms. Conclusion Our study revealed that heterozygote subjects for the IL-6 G-174C/G-597A polymorphisms were significantly overrepresented in the control group than in the Perthes patient group. Consequently, we concluded that children who are heterozygous for these polymorphisms have a lower chance of developing Perthes disease than carriers of both homozygote genotypes.

RESUMO

PURPOSE: The aim of this study was to evaluate whether ultrasound sonography (USS) performed by orthopedic surgeons is a reliable method of investigating lateral meniscus (LM) knee lesions as compared to magnetic resonance imaging (MRI), and arthroscopy, which is the gold standard in clinical practice. METHODS: In total, 107 patients were involved in this study. They were hospitalized for arthroscopy due to LM injury of the knee. Clinical examination (McMurray's, Apley's, and joint line tenderness tests), USS, and MRI were performed prior to arthroscopy. We compared the results of clinical examination, USS, and MRI with the arthroscopic findings for the knee, which were considered the reference values. RESULTS: McMurray's clinical test, which is the most sensitive method of detecting lateral meniscus lesions, gave the same sensitivity rate for both acute and chronic LM injuries: 65%. USS was observed to be more sensitive and specific for chronic LM injuries (85 and 90%, respectively) than for acute LM injuries (71 and 87%). MRI also yielded higher values of sensitivity and specificity for chronic lateral meniscus injuries (75 and 95%, respectively) than for acute LM injuries (68 and 87%). CONCLUSIONS: The accuracy of ultrasound examination is demonstrated by the high reliability of this method in the diagnosis of lateral meniscus lesions of the knee, and the evaluation performed in this study showed that ultrasound is a useful clinical tool for diagnosing knee pathology.

RESUMO

Total hip arthroplasty is most common reconstructive hip procedure in adults. In this surgery we replace some parts of the upper femur and acetabulum with biocompatible materials. The main goal of this surgery is to eliminate pain and regain full extent of joint motion, maintaining hip stability. Surgical technique, biomaterials, design of the prosthesis and fixation techniques have evolved with time adjusting to each other. After total hip arthroplasty patients' quality of life should be improved. There are many various postoperative complications. Some of them are fatal, and some are minor, which may become manifested years after surgery. Each next surgical procedure following previous hip surgery is associated with considerably lower chances to be successful. Therefore, in primary total hip arthroplasty, preoperative evaluation and preparation of patients are essential. Every orthopaedic surgeon needs to improve already adopted surgical skills applying them with precision and without compromise, with the main goal to achieve long-term durability of the selected implant. The number of total hip arthroplasties will also increase in future, and newer and higher quality materials will be used.

RESUMO

Ninety-nine hips treated by the Chiari pelvic osteotomy were included in this study designed as a retrospective review. The group consisted of 36 male and 50 female patients, with mean age of 15.6 years. Each was diagnosed with developmental dysplasia of the hip (DDH) or avascular necrosis of the femoral head--Legg-Calve-Perthes disease (LCP)--and postreduction avascular necrosis (PAN). Five hip parameters (the acetabular angle of Sharp, the center-edge (CE) angle of Wiberg, the percentage of femoral head uncoverage, the acetabular depth ratio, and the Shenton-Menard arch continuity) were evaluated. Functional outcome was assessed according to Harris hip score (HHS) and McKay criteria for clinical evaluation. The postoperative results showed improvement in all the radiographic parameters. The angle of Sharp showed a decrease of 8.62º (p < 0.01). The CE angle of Wiberg showed an increase of 28.76º (p < 0.01), and the uncoverage of the femoral head showed a decrease of 51.51% (p < 0.01). The improvement of HHS was 11.93 (p < 0.05). The patients' satisfaction was indicated by grade 4.1 ± 0.94 and the doctor's satisfaction by grade 3.7 ± 1.16. The Chiari pelvic osteotomy, in spite of the development of biologically better procedures, has retained its position in the treatment of adolescent hip disorders.

RESUMO

Feet are maybe the key part of our musculoskeletal system that establishes upright position and movement. Their role is multiple--they maintain the balance of the body, push the body forward when walking and absorb mechanical pressure created in contact with the surface. Therefore, correct anatomic and functional development of foot is of vital importance. The most frequent reasons for examination of foot in the period of development are pain, deformity and incorrect walk. Our task is to detect the cause of the problem with clinical examination in the shortest possible period of time or to assess which additional diagnostic procedure would be the most suitable. A clinical examination of foot in the period of development involves inspection, palpation, percussion, auscultation, examination of joint mobility, examination of sensory-motor function and conducting specific tests. In some cases detailed and properly conducted clinical examination can prove to be sufficient to establish a complete and accurate diagnosis. Patients of this specific age may be insufficiently cooperative, mistrustful, shy or even afraid. Our approach and manipulations during the clinical examination need to be adapted completely to such patients and their characteristics.

Clubfoot, or talipes equinovarus, is a deformity consisting of equinus, varus, and adductus foot deformity. The true etiology of congenital clubfoot is unknown; several theories have been proposed. The pathology of the individual bones contributes to the clubfoot deformity and soft tissue contractures around the ankle and talocalcaneonavicular joint maintains the deformity and involve muscles, tendons, tendon sheaths, ligaments and joint capsules. Various treatment regimens have been proposed, including the use of corrective splinting, taping, and casting. Surgery in clubfoot is indicated for deformities that do not respond to conservative treatment by serial manipulation and casting. Surgery in the treatment of clubfoot must be tailored to the age of the child and to the deformity to be corrected. The main goals of treatment is the painless, functional and anatomical normal foot without need for custom made footwear, and those can be achieved after detailed, indivudial approach with great experience in pediatric orthopedics.

RESUMO

Hallux valgus is a complex deformity of the forefoot. Beside the lateral deviation of the first metatarsophalangeal joint angle exceeding 15-20 degrees and intermetatarsalvarus exceeding 8-9 degrees, it is also characterized by extensive changes of the soft tissue arch, sesamoid mechanism and metatarsocuneiform joint. It occurs almost exclusively in humans wearing shoes. Although in some measure it can be treated non-operatively, by corrective separators and inserts, operative treatment is predominant. There are numerous operative procedures aimed at the correction of the deformity and inducing normal biomechanics of the forefoot. There are seven conceptually different procedures starting from simple bunionectomy, through various soft tissue procedures, metatarsal and phalangeal osteotomies, to resection arthroplasty and metatarsophalangeal arthrodesis. All have clear indications, and none of them has advantages over the others. In accordance with the etiopathogenesis of the disease prevention is easy; wearing comfortable shoes.

RESUMO

During the period of development foot deformities can occur, not only during the growth and development, but also in the later age. The most frequent foot deformity is flatfoot, congenital club foot and hallux valgus. Prior to the decision on surgical treatment of the deformity, whenever possible the patient should be referred for physical therapy that may yield acceptable results in specific treatment phases. The basis of the treatment involves kinesitherapy, application of certain agents (thermotherapy, electrotherapy, ultrasound) and orthosis for maintaining corrections. If such therapy does not yield satisfactory results, the deformity is surgically corrected. After surgical correction, physical procedures can contribute to more rapid recovery and decrease possible complications (pain, edema, complex regional pain syndrome--Mb Sudec), which can follow the surgical correction of the deformity. In addition, the obligatory form of rehabilitation also involves kinesitherapy.
