Background THA for high-riding developmental dysplasia of the hip (DDH) is challenging in terms of length equalization. Although previous studies suggested preoperative templating on AP pelvic radiographs is insufficient in patients with unilateral high-riding DDH because of hypoplasia of the hemipelvis on the affected side and unequal femoral and tibial length on scanograms, the results were controversial. The EOS™ (EOS™ Imaging) is a biplane X-ray imaging system using slot-scanning technology. Length and alignment measurements have been shown to be accurate. We used the EOS to compare the lower limb length and alignment in patients with unilateral high-riding DDH. Questions/purposes (1) Is there an overall leg length difference in patients with unilateral Crowe Type IV hip dysplasia? (2) In patients with unilateral Crowe Type IV hip dysplasia with an overall leg length difference, is there a consistent pattern of abnormalities in the femur or tibia that account for observed differences? (3) What is the impact of unilateral high-riding Crowe Type IV dysplasia on femoral neck offset and knee coronal alignment? Methods Between March 2018 and April 2021, we treated 61 patients with THA for Crowe Type IV DDH (high-riding dislocation). EOS imaging was performed preoperatively in all patients. Eighteen percent (11 of 61) of the patients were excluded because of involvement of the opposite hip, 3% (two of 61) were excluded for neuromuscular involvement, and 13% (eight of 61) had previous surgery or fracture, leaving 40 patients for analysis in this prospective, cross-sectional study. Each patient’s demographic, clinical, and radiographic information was collected with a checklist using charts, Picture Archiving and Communication System, and an EOS database. EOS-related measurements that were related to the proximal femur, limb length, and knee-related angles were recorded for both sides by two examiners. The findings of the two sides were statistically compared. Results The overall limb length was not different between the dislocated and nondislocated sides (mean 725 ± 40 mm versus 722 ± 45 mm, mean difference 3 mm [95% CI -3 to 9 mm); p = 0.08). Apparent leg length was shorter on the dislocated side (mean 742 ± 44 mm versus 767 ± 52 mm, mean difference -25 mm [95% CI -32 to 3 mm]; p < 0.001). We observed that a longer tibia on the dislocated side was the only consistent pattern (mean 338 ± 19 mm versus 335 ± 20 mm, mean difference 4 [95% CI 2 to 6 mm]; p = 0.002), but there was no difference between the femur length (mean 346 ± 21 mm versus 343 ± 19 mm, mean difference 3 mm [95% CI -1 to 7]; p = 0.10). The femur of the dislocated side was longer by greater than 5 mm in 40% (16 of 40) of patients and shorter in 20% (eight of 40). The mean femoral neck offset of the involved side was shorter than that of the normal side (mean 28 ± 8 mm versus 39 ± 8 mm, mean difference -11 mm [95% CI -14 to -8 mm]; p < 0.001). There was a higher valgus alignment of the knee on the dislocated side with a decreased lateral distal femoral angle (mean 84° ± 3° versus 89° ± 3°, mean difference - 5° [95% CI -6° to -4°]; p < 0.001) and increased medial proximal tibia angle (mean 89° ± 3° versus 87° ± 3°, mean difference 1° [95% CI 0° to 2°]; p = 0.04). Conclusion A consistent pattern of anatomic alteration on the contralateral side does not exist in Crowe Type IV hips except for the length of the tibia. All parameters of the limb length could be shorter, equal to, or longer on the dislocated side. Given this unpredictability, AP pelvis radiographs are not sufficient for preoperative planning, and individualized preoperative planning using full-length images of the lower limbs should be performed before arthroplasty in Crowe Type IV hips.

Tailbone pain is a fairly common pain in the bottom of backbone that spreads towards sacrum and lower legs. Its prevalence in women is more than men and often occurs at 40s 1. The pain at the bottom of tailbone has often vague causes, which a part of it is due to the complex structure of sacrococcygeal. The pain is sometimes concerned with damage after direct trauma, childbirth or

Background: Vascular thromboembolism is one of the major concerns of orthopedic surgeons after hip or knee replacement surgery. Although many thromboprophylactic drugs have been introduced, there is still no consensus over their efficacy and safety. Therefore, this study aimed to compare the efficacy and safety of oral rivaroxaban and aspirin administration and enoxaparin injections in patients undergoing knee or hip replacement. Objectives: Determination and comparison of the side effect and efficacy of Rivaroxaban and Enoxaparin after total hip or knee arthroplasty. Methods: A total of 231 patients undergoing knee or hip replacement surgery were included in the study. Of them, 31 patients were excluded due to missing the follow-up. Of the remaining 200 patients, 42 low-risk and 158 moderate- to high-risk patients were identified, according to Caprini risk assessment model. Then, they were divided into three groups: aspirin (42 patients), enoxaparin (78 patients), and rivaroxaban (80 patients). Severe hemorrhage (hemoglobin reduction of more than 2 g/dL or requiring blood transfusion) was assessed after the first dose of medication until discharge through daily hemoglobin testing. Frequency of other side effects such as wound complications (ecchymosis, hematoma, and wound infection) and gastrointestinal or skin problems was recorded and compared by daily examination during the hospital stay and then in the future visits to the clinic up to 6 months in each group. Follow up visits were performed at weeks 6, 12, and 24. Results: No cases of deep vein thrombosis or pulmonary thromboembolism were observed in any of the study groups. There was no significant difference between the two groups in the number of major bleeding cases (P=0.39). Ecchymosis around the wound was significantly higher in the rivaroxaban group than in the enoxaparin group (33.8% vs. 23%). However, this difference was not statistically significant (P=0.06). Conclusion: The efficacy and safety of rivaroxaban and enoxaparin drugs are comparable. Although ecchymosis was seen after using rivaroxaban rather than enoxaparin, rivaroxaban is orally administered and costs less for the patient and the health system. So, its use as a thromboprophylactic drug of choice following hip and knee arthroplasty surgery is still recommended.

Introduction: Depression is considered as the most common psychological problem in societies. Depression, anxiety disorders, and substance abuse are more common in patients with pain compared to the general population. In this study, the state of depression in patients with upper limb pain with radiculopathy or without paraclinical signs of radiculopathy has been investigated. Material and Methods: We conducted the depression status in patients with upper limb pain with and without radiculopathy in a descriptive cross-sectional study in Sari in 2017. Beck Depression Inventory (BDI-II), Short Form (36) Health Survey (SF-36), short-form McGill pain questionnaire was used to evaluate the status of major depressive disorder, health status and quality of life, and severity of pain in them, respectively. The data was analyzed by SPSS 22.   Results: From 120 patients with the mean age 44.97±9.77 years, 19% had mild depression, 18% moderate depression and 11% severe depression. The mean score of SF36 was 29.94±6.86. The mean scores of McGill pain scale was 13.31±6.02. The mean depression score had a significant difference between the two groups studied (P=0.04). The McGill pain score had also a significant difference between the two study groups (P=0.012). The mean score of SF36 had no significant difference in both groups (P=0.41).Conclusion: The depression score and the prevalence of moderate and severe depression were also higher in patients with chronic upper limb pain with cervical radiculopathy than in patients without cervical radiculopathy.

Introduction: Chronic pain is one of the most common diseases in today's world, which has a serious influence on the quality of life. Low back pain (LBP) is very common in developed and developing countries. This study aimed to investigate anxiety & depression as a disability factor in chronic LBP in patients referred to the Orthopedic Clinic of Touba Clinic in Sari, Iran in 2018. Material and Methods: The Ronald-Morris Disability Questionnaire was used to assess disability, the Beck Anxiety Questionnaire was used to assess anxiety, the Beck Depression Questionnaire was used to assess depression, the SF-36 was used to assess quality of life, and the Visual Analog Scale was used to assess pain.    Results: In this study, 100 patients were studied. Seventy were female and 30 were male. The mean age of patients was 45.05 ± 11.45 years. Sixty five patients suffered from depression and 35 patients had normal depression. The mean score for disability was 14.05, and the mean and standard deviation from the pain score of patients was 36.2 ± 2.7. Conclusion: Depression is one of the disability factors in people with chronic LBP in patients referring to the orthopedic clinic of Touba Clinic in Sari city in 2018.

Background:The conventional graft harvesting site in a Salter osteotomy might impair the cosmetic appearance of patients with developmental dysplasia of the hip (DDH). The authors evaluated if an alternative graft donor site on the iliac bone could eliminate this concern. Methods:In a prospective study, 23 patients who had DDH with an indication for Salter osteotomy were included. In 10 patients (study group), the vertical triangular graft was harvested from the one-third anterolateral section of the iliac wing. In the remaining 13 patients (control group), the graft was harvested from the conventional site. The radiographic measures, including acetabular index and center edge angle, Severin criteria, clinical outcomes (McKay criteria), and complication rates of the two groups were compared. Results:The clinical outcome, acetabular index, center-edge angle, and Severin criteria of the patients of the two groups were statistically comparable. Union of harvested sites was seen in all patients. The mean duration of surgery and blood loss were statistically comparable (P = 0.49 and P = 0.33, respectively). The rate of osteonecrosis was similar in the two groups. The only graft site morbidity was the anterior superior iliac spine (ASIS) asymmetry that was seen in all patients of the control group and no patients of the study group; a mean horizontal level difference of 2.2 ± 0.5 cm was observed between the affected and unaffected ASIS of the control group. Conclusions:Vertical triangular graft harvest from the one-third anterolateral section of iliac wing in Salter osteotomy improves the cosmetic outcome through the reduction of pelvic deformity.

Background: Femoral Neck Fracture (FNF) is prevalent in young people. It is mostly due to high-energy trauma and creates many challenges in surgical repair. A few patients with hip fractures can fully recover from the injury and act independently in their daily activities. In this study, we evaluated the results of FNF operation in patients younger than 60 years.  Objectives: This study was conducted to evaluate the outcome of femoral neck surgery in young patients and comparison the complications according to types of surgery ,age,delay and type of FNF fracture.  Methods: This study was a retrospective-prospective descriptive and analytical study on patients 15 to 60 years old with FNF from 2013 to 2017. The surgical efficacy and its results were evaluated using the Harris Hip Scale (HHS). The obtained data were analyzed in SPSS version V. 24.  Results: The Mean±SD age of 53 study patients was 42.07±12.5 years. The Mean±SD femoral neck shortening was 7.05±5.42 mm, and the HHS score was 82.7±6.9. Avascular Necrosis (AVN) was seen in 10 (18.9%), malunion in 11 (20.8%), nonunion in 1 (1.9%)  and failure in 3 (5.7%) patients. Eight patients had reoperation procedures. The type of fracture, delay in surgery, type of operation, and the shortening of the femoral neck were predictive factors of postoperative complications (P<0.05).  Conclusion: According to this study, reducing the delay for surgery, increasing anatomic reduction, and preventing the shortening of the femoral neck can improve the quality of life, reduce complications, and decrease the economic burden.
