RESUMO

Background and Objectives: This study aimed to determine the relationship between non-simultaneous contralateral hip fractures, urban and rural differences, fracture localization, time between fractures, physiotherapy applications, comorbidity, and the second fracture outcomes. Materials and Methods: We retrospectively analyzed 107 patients aged 65 and older with proximal femur fractures (PFFs) who underwent surgery at Düzce University Medical Faculty between January 2010 and December 2022. High-energy fractures, pathological fractures, and patients with a history of old fractures were excluded. Results: The study included 66 females (61.7%) and 41 males (38.3%), with a mean age of 83.76 years. The mean interval between two fractures was 28.3 months. There was no statistical difference between the localization of the first and second fractures (p = 0.107). However, there was a significant difference in the first PFF localizations of patients living in rural areas (p = 0.023). Patients with heart failure, respiratory failure, osteoporosis, and cognitive impairment had shorter intervals between fractures (p < 0.001). Conclusions: This study shows that age, female gender, place of residence, comorbid diseases, and whether physical therapy is received after the first fracture are significant risk factors for a second hip fracture in patients over 65 years of age.

RESUMO

Pigmented villonodular synovitis (PVNS) is a rare, relatively benign intra-articular lesion characterized by slowly progressing proliferation of the synovial tissue. It is most commonly observed in the knee joint. Localized and diffuse types are two types of PVNS depending on the synovial involvement. Arthroscopic and excisional resections are recommended as the treatment methods for the PVNS. Radiotherapy or chemotherapy can be adjuvant therapeutic options for the widespread masses. In this study, we presented a case of diffuse PVNS originating from the patellar fat pad.

RESUMO

BACKGROUND: Fractures are common extremity injuries in pediatric orthopedic practice. The aim of this study is to determine the relationship between pediatric extremity fractures and visual impairments. METHODS: Thirty pediatric patients who were admitted to the emergency and orthopedics and traumatology clinic due to an extremity fracture after a fall were included in the study. Following fracture treatment, the patients were evaluated in terms of ocu-lar findings before discharge from the hospital. Thirty age- and sex-matched healthy children who presented to the ophthalmology department for routine care were also recruited as the control group. All participants underwent a comprehensive ophthalmologic examination, including cycloplegic refraction, visual acuity levels, and near stereoacuity measurement. RESULTS: The number of male participants was higher in both groups. There was no significant difference between the groups in terms of age and gender distribution. The most common upper extremity fractures were observed to be distal radius (52%) and distal humerus fractures (28%). The number of patients who had a refractive error that required spectacles was significantly higher in the fracture group (p=0.039). When the visual acuity levels of the better eye were evaluated, the mean visual acuity was significantly lower in the fracture group (p=0.016). The mean stereoacuity was also significantly lower in the study group (<0.001). In the binary logistic regression analysis model, low stereopsis levels were associated with the risk of pediatric extremity fractures (95% CI: 1.056-1.385; p=0.006). CONCLUSION: Our study showed that low-energy pediatric extremity fractures are more common in children with visual im-pairments that require treatment, and low stereopsis is a risk factor for fractures. Consequently, regular eye examinations and early treatment of visual impairments in children may help to prevent fall-related injuries.

RESUMO

OBJECTIVES: This study aims to evaluate the effect of adipose-derived stromal vascular fraction (SVF) on osteochondral defects treated by hyaluronic acid (HA)-based scaffold in a rabbit model. MATERIALS AND METHODS: Eighteen white New Zealand rabbits were randomly grouped into the experimental group (n=9) and control group (n=9). In all groups, osteochondral defects were induced on the weight-bearing surfaces of the right femoral medial condyles, and a HA-based scaffold was applied to the defect area with microfractures (MFs). In this study, 1 mL of adipose-derived SVF was injected into the knee joints of the rabbits in the experimental group. For histological and macroscopic evaluation, four rabbits were randomly selected from each group at Week 4, and the remaining rabbits were sacrificed at the end of Week 8. Macroscopic assessments of all samples were performed based on the Brittberg scoring system, and microscopic evaluations were performed based on the O'Driscoll scores. RESULTS: Samples were taken at Weeks 4 and 8. At Week 4, the O'Driscoll scores were significantly higher in the control group than the experimental group (p=0.038), while there was no significant difference in the Brittberg scores between the two groups (p=0.108). At Week 8, the O'Driscoll score and Brittberg scores were statistically higher in the experimental group than in the control group (p=0.008 and p=0.007, respectively). According to the microscopic evaluation, at the end of Week 8, the cartilage thickness was greater in the experimental group, and nearly all of the defect area was filled with hyaline cartilage. CONCLUSION: Application of adipose-derived SVF with MF-HA-based scaffold was better than MF-HA-based scaffold treatment in improving osteochondral regeneration. Therefore, it can be used in combination with microfracture and scaffold to accelerate cartilage regeneration, particularly in the treatment of secondary osteoarthritis.

RESUMO

BACKGROUND: Total knee arthroplasty (TKA) operation is an effective treatment method in severe osteoarthritis worldwide. However, the number of patients with chronic pain and functional limitations in the postoperative period will continue to increase. Kinesiphobia is an important factor that affects the functional outcomes postoperatively. The aim of this study is to investigate the effects of intraoperative consciousness of the patients during surgery on kinesiophobia development and early functional outcomes of TKA. METHODS: Sixty patients with the diagnosis of primary knee osteoarthritis were enrolled in the study. Tampa Scale of Kinesiophabia (TSK) was obtained for each patient at multiple time periods. Regional anaesthesia and deep sedation were performed on group 1 (n = 30), while regional anaesthesia and light sedation were performed on group 2 (n = 30). The same surgical procedures were applied to all participants. Functional tests were performed on the patients at the postoperative 2nd and 5th days. Visual Analogue Scale (VAS) scores and knee flexion angles were also measured postoperatively. RESULTS: The mean age of the participants (19 men (31.7%) and 41women (68.3%)) was 67.7 ± 6.7 (54-82) years. TSK ≥ 40 was detected in 18 (30%) patients preoperatively and 33 patients (55%) postoperatively. The number of kinesiophobic patients showed statistically significant increase after operation (20/30 (66.7%)) according to preoperative period (9/30 (30%)) in group 2 (p = 0.003). Postoperative functional scores, knee flexion angles and VAS scores were better in non-kinesiophobic patients. Conclusion: Patient's consciousness during TKA operations is an important factor that interferes with the postoperative kinesiophobia development, which may play a pivotal role affecting the early mobility and functional outcomes.

RESUMO

PURPOSE: The position of the patella according to the femur is very important in the evaluation of patella-femoral joint disorders. In 1938, Blumensaat (BS) described the BS line to evaluate the patella femoral congruence. This method is still valuable in clinical use. There is a limited number of studies demonstrating the accuracy of BS method as well as the affected variables. The aim of this study was to evaluate o the age and gender-related changes in the BS line. METHODS: Standard lateral knee radiography was performed to all patients at 30° flexion. The relationship between the BS line and the patella inferior pole was examined and the variability of the measurements according to gender and age groups was investigated by statistical methods. RESULTS: Ninety-five patients (43 men and 52 women) were enrolled in the study. Mean age of the patients were 43.7 ± 14.1 years (48.2 ± 11.7, 37.9 ± 14.8 in women and men, respectively). The BS line was passed through the inferior pole of the patella in only 2 (2.1%) of 95 patients. There was a statistically significant difference (p = 0.041) between BS measurement and gender which was found to be higher in females than males. There was no statistically significant correlation with this distance between the age groups (r = - 0.216, p = 0.427). CONCLUSION: In our study, it was concluded that BS measurement differs according to gender but did not have any difference between different age groups.

RESUMO

BACKGROUND: Microfracture and scaffold application in the treatment of osteochondral defects is still one of the most frequently used methods in the clinic. The most important step in this treatment method is the stabilization of fibrin clot. Tranexamic acid (TA) is an antifibrinolytic agent commonly used in orthopedic surgery in recent years. This study evaluated the effect of local TA application on healing of experimentally induced osteochondral defects on rabbits. METHODS: This paper contains an animal in vivo data and histological outcomes on the effect of TA. Eighteen New Zealand white rabbits were treated unilaterally and cylindrical defects having a width of 4 mm and depth of 5 mm were created in the weight-bearing surfaces of the medial and lateral condyles of the right femur. They were divided into two groups, as group 1 study and group 2 control groups, respectively. One milliliter (ml) of TA was injected into the knee joints of the subjects in group 1. All animals were sacrificed for the extraction of the femur condyles for histologic study at the fourth and eighth weeks after surgery. Histological evaluations were performed by Brittberg and O'Driscoll scores to all samples. Data were organized in a Standard Statistical Package System v.22 software package (SPSS/PC Inc., Chicago, IL.) and reported as mean and median (min-max). Repeated measures ANOVA test was used to compare groups and condyle effects together for each week. p values below 0.05 were considered as statistically significant. RESULTS: Samples were taken in the fourth and eighth weeks. The regularity of the surface in group 1 was smoother, and the tissue stability was more robust. Mean Brittberg scores in both weeks were statistically higher in group 1 when compared with group 2. In the microscopic evaluation, it was observed that the regeneration of subchondral and cartilage tissues were more rapid and organized in group 1, and the mean O' Driscoll scores in both weeks were statistically higher in group 1. CONCLUSIONS: Application of TA improves the healing time and tissue stability in osteochondral defects which are implanted a-cellular scaffold after microfracture and should be applicable to humans for the treatment of osteochondral defects.

RESUMO

Hip is a stabilized joint due to the surrounding ligaments, and muscles, which can dislocate as a result of high energy trauma, high-level falls, and motor vehicle accidents. Traumatic hip dislocations can either be isolated or simultaneously with acetabular and proximal femur fractures. At the same time injury of sciatic, femoral or obturator nerves can be seen. However, avascular necrosis of femoral head, posttraumatic osteoarthritis, and heterotopic ossifications can be seen as prolonged complications. The period prior to the reduction, severity of the trauma, and performing open or close reductions are the major contributors of the prognosis. As an extremely rare entity, bilateral asymmetrical hip dislocations are reported as the 0.01-0.02% of all joint dislocations. Accompanying proximal femoral fractures are pointed out 17%, one of them is femoral head fractures which are orthopedic emergencies that need to be fixed with surgery. However, high incidence of AVN is reported at the end of 2 years even if following early reductions. In our article, traumatic bilateral asymmetric hip dislocations and femoral head fracture is described in the context of a diagnosis, treatment and follow-up.

RESUMO

OBJECTIVES: The aim of this study is to compare the effect of extracorporeal shock wave therapy (ESWT) on fractures with intact periosteum and excised periosteum. MATERIALS AND METHODS: Thirty-seven Wistar albino rats were randomized into four groups. Osteotomy and intramedullary Kirschner wire fixation were performed on all right femurs under ketamin anesthesia. The first group (n=10) was identified as control group. In the second group (n=10), periosteum located at the osteotomy site was excised circumferentially during surgery. In the third group (n=9), periosteum was left intact and ESWT was applied. In the forth group (n=8), periosteums of all rats were excised and ESWT was applied. All fracture lines were evaluated radiographically each two weeks and histologically at the sixth week. Results were evaluated statistically. RESULTS: In periosteum excised group which represents a model of open fractures with soft tissue defect, ESWT application had a significantly positive histologic effect on bone healing. However, radiological evaluation did not reveal any statistically significant difference between groups with intact and excised periosteums. CONCLUSION: According to our findings, ESWT can be used to improve fracture healing and prevent pseudoarthrosis in the treatment of open fractures with accompanying soft tissue and periosteum damage. However, further clinical studies are required to include ESWT in routine practice.

RESUMO

BACKGROUND: The aim of this study was to evaluate the results of high-dose extracorporeal shockwave therapy applied with an ankle block and corticosteroid injection in patients with plantar fasciitis whose symptoms persisted for more than 6 months. METHODS: Sixty patients were assessed clinically at presentation and at 3-month follow-up with a patient-assessed 100-mm visual analog scale of pain and a physician-assessed heel tenderness index. A therapeutic response rate was evaluated. A decrease of at least 50% from baseline to 3 months in visual analog scale or heel tenderness index scores was accepted as a successful result. RESULTS: Extracorporeal shockwave therapy and corticosteroid injection provided significant improvements in visual analog scale and heel tenderness index scores, but between the two groups there was no significant difference in the visual analog scale score change 3 months after treatment (P > .05). Twenty-seven of 33 patients (82%) in the extracorporeal shockwave therapy group and 23 of 27 (85%) in the corticosteroid injection group had a successful therapeutic response after 3 months. CONCLUSIONS: Corticosteroid injection and extracorporeal shockwave therapy are successful treatment modalities for plantar fasciitis. Corticosteroid injection treatment is cost effective compared with extracorporeal shockwave therapy, and corticosteroid injection may be the first treatment choice according to these results.

RESUMO

BACKGROUND: This study was performed to evaluate the treatment of complex regional pain syndrome (CRPS) type I with stellate ganglion blockade. MATERIALS AND METHODS: We performed three blockades at weekly intervals in 22 patients with CRPS type I in one hand. The patients were divided into two groups depending on the time between symptom onset and treatment initiation. Group 1and 2 patients had short and long symptom-onset-to-treatment intervals, respectively. Pain intensity, using a visual analog score (VAS), and range of motion (ROM) for the wrist joint were assessed before and 2 weeks after treatment and were compared using nonparametric statistical analysis. RESULTS: Treatment produced a statistically significant difference in wrist ROM for all patients (P < 0.001). VAS values showed an overall decrease from 8 +/- 1 to 1 +/- 1 following treatment, and there was a significant difference in VAS value between groups 1 and 2 (P < 0.05). CONCLUSIONS: We concluded that stellate ganglion blockade successfully decreased VAS and increased ROM of wrist joints in patients with CRPS type I. Further, the duration between symptom onset and therapy initiation was a major factor affecting blockade success.

RESUMO

BACKGROUND: The histologic and biomechanical effects of intra-articular hyaluronic acid on the anterior cruciate ligaments of rats were investigated. METHODS: Thirty rats were divided into three groups, i.e., the hyaluronic acid group, saline group, and control group. The hyaluronic acid and saline groups received a total of four intra-articular injections, whereas no injection was administered to the control group. The hyaluronic acid group was injected with 50 microg (0.05 cc) hyaluronic acid, and the saline group was injected with 50 microl (0.05 cc) of 0.9% sodium chloride solution. All of the rats were sacrificed on day 29 and the femur-anterior cruciate ligament-tibia complexes from the right knees were prepared, tested mechanically, and evaluated histologically. FINDINGS: The mode of failure involved the midsubstance of the anterior cruciate ligament in all the specimens. There were no statistically significant differences in the stiffness and ultimate load to failure values between the three groups (P>0.05). The energy to failure values were evaluated and there was no statistically significant difference between the groups (P=0.064, chi-square=3.43). In the histologic analyses, there was a significant difference in the hyalinization values between the hyaluronic acid and saline groups (P=0.029) and between the hyaluronic acid group and control groups (P=0.029). INTERPRETATION: The present study shows that intra-articularly delivered hyaluronic acid has no statistically significant effect on the tensile strength of the rat anterior cruciate ligament. Although hyalinization was increased, no difference was found on the other markers for degenerative changes. We conclude that intra-articular hyaluronic acid injections can be performed safely, although the use of a precise injection technique is recommended.

RESUMO

BACKGROUND: The aim of the study was to compare the efficacies of steroid injections guided by scintigraphy, ultrasonography, and palpation in plantar fasciitis. METHODS: A total of 35 heels of 27 patients were randomly assigned to three steroid injection groups: palpation-guided (pg), ultrasound-guided (ug), and scintigraphy-guided (sg). Patients were evaluated for pain intensity before the injections and at the last follow-up of 25.3 months with a 100-mm visual analog scale (VAS). RESULTS: There were significant improvements in plantar fascia thickness, fat pad thickness, and VAS. Among the three groups of ug-pg, ug-sg, and pg-sg there were no statistically significant differences after treatment (P = 0.017, MWU = 36.5; P = 0.023, MWU = 29.5; and P = 0.006, MWU = 13, respectively). CONCLUSIONS: The ug, pg, and sg injections were effective in the conservative treatment of plantar fasciitis. We are of the opinion that steroid injections should be performed, preferably with palpation or ultrasonographic guidance.

RESUMO

PURPOSE: Intrathecal morphine is administered to provide profound and prolonged analgesia, and to treat acute postoperative pain. We compared the effectiveness of hyperbaric bupivacaine alone and in combination with morphine for unilateral spinal anesthesia in patients undergoing knee arthroscopy. METHODS: Sixty patients were randomly allocated to two groups to receive either 1.2 ml (6 mg) of 0.5% hyperbaric bupivacaine (group B; n = 30) or 1.2 ml of 0.5% hyperbaric bupivacaine containing 0.16 mg of morphine (group BM; n = 30). Spinal block was assessed by pinprick and a modified Bromage scale and compared between the operated and nonoperated sides. Visual analog scale (VAS) values, duration of analgesia, and total analgesic requirement of patients were recorded. RESULTS: Patients in group BM had significantly lower VAS values on movement at 30 min and at 2, 4, 6, and 12 h postoperatively (P < 0.05 and P < 0.001, P < 0.001, P < 0.001, and P < 0.05, respectively). The total analgesic requirement in the first 24 h after surgery was significantly higher in group B (P < 0.001). Patients in group BM had a significantly longer duration of analgesia in the first 24 h postoperatively (P < 0.001). Motor blockade of the operated limb in group BM was similar to that in group B (P > 0.05), and motor blockade of the nonoperated limb in group BM was also similar to that in group B (P > 0.05). CONCLUSION: We conclude that unilateral spinal anesthesia with hyperbaric bupivacaine plus 0.16 mg morphine is preferable to hyperbaric bupivacaine alone with respect to analgesic requirement, duration of analgesia, and VAS values.
