Abstract Background In dogs, thermal imaging has been documented only recently, but a growing interest in this modality has led to studies using thermography to assess pathologies in the canine hip, stifle, elbow, intervertebral disc, and bone neoplasia. This study aimed to evaluate the use of digital thermography in assessing and evaluating treatment response in dogs with hip osteoarthritis (OA) and comparing its results with an objective measure and two clinical metrology instruments. In an experimental, randomized, double-blinded study, one hundred hip joints of fifty police working dogs with bilateral hip OA were evaluated. A dorsoventral and lateral thermographic image were obtained on days 0, 8, 15, 30, 90, and 180. Mean and maximal temperatures were determined. Additionally, the animal’s weight-bearing distribution and radiographic examination of the hip joint (extended legs ventrodorsal view) were performed. Copies of the Canine Brief Pain Inventory (CBPI) and Canine Orthopaedic Index (COI) were obtained. Results were analyzed by ANOVA, followed by an LSD post-hoc test, and correlations were assessed with Spearman correlation coefficient, with p < 0.05. Results Values recorded on the lateral view were higher than those on the dorsoventral view. No differences or correlations were found between Orthopedic Foundation for Animals hip grades and temperature. Digital thermographic images showed a weak significant correlation with weight-bearing evaluations (r = 0.13, p < 0.01) and different clinical metrology instruments scores (r = − 0.25, p < 0.01 for pain severity score, and r = − 0.21, p = 0.04 for gait). It also correlated with radiographic findings, specifically the circumferential femoral head osteophyte and caudolateral curvilinear osteophyte. Conclusion To our knowledge, this is the first study presenting the digital thermography assessment of Police working dogs submitted to treatment for hip OA. Digital thermography, mainly based on a lateral view evaluation, showed a weak significant correlation with stance analysis and clinical metrology instruments scores.

Objective This study aimed to compare the symmetry of clinical and radiographic signs of right and left pelvic limbs of dogs with bilateral hip osteoarthritis (OA) and evaluate the association of physical findings and radiographic abnormalities. Patients and methods One hundred pelvic limbs of police working dogs with bilateral hip OA were evaluated, following a screening program. Weight distribution, joint range of motion at flexion and extension, thigh girth, and radiographic signs were recorded and compared with the results of the contralateral limb and by breed, age, and sex with the Paired Samples T-Test and Pearson correlation coefficient, with p<0.05. Results The sample mean age was 6.5±2.2 years, and the bodyweight of 26.7±5.3kg. No significant differences were observed when comparing weight distribution, joint range of motion, and thigh girth of left and right limbs. Weight distribution and age showed a statistically significant correlation with joint extension. The right limbs showed a significantly higher frequency of circumferential femoral head osteophyte (CFHO) regarding radiographic signs. Limbs with CFHO or caudolateral curvilinear osteophyte had significantly larger joint flexion angle (p = 0.02) and smaller extension angle (p<0.01), respectively, compared to those that did not. Age showed a significant correlation with the presence of several radiographic findings, as did different breeds. Conclusion Clinical and radiographic signs occur symmetrically in naturally occurring hip OA in police working dogs. Several correlations were observed between the evaluations performed and differences between breeds, which can be useful in assessing and early diagnosis of hip OA.

Abstract Background Digital thermal imaging is a physiologic, non-invasive, contactless, and non-radiating diagnostic tool that can assess a wide range of musculoskeletal conditions, including hip osteoarthritis (HOA). Fifty police working dogs were evaluated to compare the dorsoventral (DV) and lateral (LT) thermographic images in dogs with naturally occurring bilateral HOA. A DV, and left and right lateral LT images were obtained for each animal in six different moments. They were positioned standing in a symmetrical upright position for the DV view. Each image included the area from the last lumbar to the first coccygeal vertebrae. Each LT view was set with the greater trochanter in the centre of the image. Images were taken with a thermographic camera from a distance of 60 cm. Mean and maximal temperatures were recorded, analyzed with ANOVA, dependent samples t-test, and Spearman correlation, with P < 0.05. Results Nine hundred images were considered, collected from 30 males and 20 females, with a mean age of 6.5 ± 2.2 years and bodyweight of 26.7 ± 5.3 kg. The overall value recorded on the DV view was 25.3º ± 9.1 and 28.4º ± 2.8 on the lateral view. These were significantly different (P < 0.01) and with a low correlation (r = 0.10, P = 0.03). German Shepard dogs showed significantly lower values on all views than other breeds (P < 0.01), and heavier dogs had higher values on the lateral view. Conclusions This is the first study that describes digital thermography's diagnostic use to evaluate working dogs with naturally occurring HOA, comparing two different views. Future studies should address each one's value in the diagnosis and response to treatment of this disease.

Radiographic Findings

In the present study, the radiographic examination of the distal and proximal interphalangeal joints was performed in 43 randomly selected horses. A total of 86 forelimbs were examined. On the forelimbs, dorsolateral-palmaromedial, and dorsomedial-palmarolateral oblique views were performed. The oblique views were performed on raised limbs placed in a navicular block and on weight-bearing limbs placed on a pedestal made at the equine clinic. In total, 688 dorsolateral-palmaromedial and dorsomedial-palmarolateral views were taken. During the evaluation of the radiographs we focused on the detection of signs of degenerative joint disease of the distal and proximal iterphalangeal joints, and the detection of new bone formation in the phalanx regions, not associated with a disease of the distal or proximal interphalangeal joints. Based on the radiographic signs visible on these views, we diagnosed 9 cases of degenerative joint disease of the distal intraphalangeal joint, 13 cases of the degenerative joint disease of the proximal intraphalangeal joint and 21 cases of new bone formation in the phalanx regions. These signs were observed in 253 of 688 oblique views. Positive radiographic findings of the above-mentioned disorders were shown on 127 oblique views of the raised limb placed in the navicular block and 126 oblique views of the weight-bearing limb placed on the pedestal we made. When 128 oblique views of the weight-bearing limb (placed on the pedestal) were compared with those of the raised limb (in the navicular block), there were different radiographic findings in three cases only. The differences in detection rates of radiographic signs between different type views showed no statistical significance (p ≥ 0.05). Therefore we assume that the pedestal we made can be routinely used for the radiographic examination of the distal and proximal interphalangeal joints on DL-PM and DM-PL oblique views, as part of pre-purchase examination or diagnosis of lameness.

Objectives: To compare the effect of intra-articular treatment with triamcinolone hexacetonide (TH), stanozolol, hyaluronan, and a platelet concentrate in police working dogs with bilateral hip osteoarthritis (OA).Study Design: Prospective, longitudinal, double-blinded, negative controlled study.Sample Population: Fifty police working dogs with naturally occurring hip OA.Methods: Animals were randomly assigned to a control group (CG, n = 10), TH group (THG, n = 10), platelet concentrate group (PCG, n = 10), stanozolol group (SG, n = 10), and Hylan G-F 20 group (HG). On days 0 (T0), 8, 15, 30, 90, and 180 days post-treatment, weight-bearing distribution was evaluated. In those days, and on days 60, 120, and 150, four clinical metrology instruments were completed. Kaplan–Meier estimators were conducted and compared with the log-rank test. Cox proportional hazard regression analysis was performed to determine treatment survival. Significance was set at p &lt; 0.05.Results: Patients had a mean age of 6.5 ± 2.4 years and body weight of 26.7 ± 5.2 kg. At T0, hips were classified as mild (n = 35), moderate (n = 10), and severe (n = 5), according to the Orthopedic Foundation for Animals grading scheme. No differences were found between groups at that moment considering age, body weight, OFA hip score, and all assessments performed. All treatments improved clinical signs in various OA dimensions in some groups, with a broad effect interval. PCG showed a lower range of variation while maintaining a positive result for more extended periods (p &lt; 0.01 for symmetry index and 0.01 &lt; p &lt; 0.04 in the majority of scores). Breed, age, sex, and OFA grade did not significantly influence response to treatment.Conclusions and Clinical Relevance: This is the first prospective, negative controlled, double-blinded study to compare the effect of a single administration of these IA treatments in dogs with hip OA. HG and PCG recorded more significant improvements throughout the 180-day follow-up. In particular, PCG also registered a lower variation in results, seemingly the best therapeutic option. Nevertheless, improvements were still observed in THG and SG, and these treatment options can be considered, mainly when the first two treatments are not available.

Gait Kinematics

Abstract Background: Hip osteoarthritis (OA) is a musculoskeletal condition that makes walking difficult due to pain induced by weight-bearing activities. Treadmills that support the body weight (BW) reduce the load on the lower limbs, and those equipped with a lower-body positive-pressure (LBPP) device, developed as a new method for unweighting, significantly reduce pain in patients with knee OA. However, the effects of unweighting on gait kinematics remain unclear in patients with hip OA. Therefore, we investigated the effects of unweighting on kinematics in patients with hip OA during walking on a treadmill equipped with an LBPP device. Methods: A total of 15 women with hip OA and 15 age-matched female controls wore a three-dimensional (3-D) motion analysis system and walked at a self-selected speed on the LBPP treadmill. Data regarding self-reported hip pain using a numeric rating scale (NRS) in which the scores 0 and 10 represented no pain and the worst pain, respectively, under three different BW conditions (100%, 75%, and 50%) were collected. Moreover, 3-D peak joint angles during gait under each condition were calculated and compared. Results: In the hip OA group, the NRS pain scores at 50% and 75% BW conditions significantly decreased compared with that at 100% BW condition (50%, P=0.002; 75%, P=0.026), and the peak hip extension angle decreased compared with that in the healthy controls (P=0.044). In both groups, unweighting significantly decreased the peak hip (P<0.001) and knee (P<0.001) flexion angles and increased the peak ankle plantar flexion angle (P<0.001) during walking. Conclusions: Unweighting by the LBPP treadmill decreased pain in the hip OA group but did not drastically alter the gait kinematics compared with that in the control group. Therefore, regarding the use of the LBPP treadmill for patients with hip OA, clinicians should consider the benefits of pain reduction rather than the kinematic changes.

Objective To evaluate the effect of an intra-articular (IA) administration of triamcinolone hexacetonide, compared with saline. Patients and methods Forty (N = 40) hip joints were randomly assigned to a treatment group (THG, n = 20, receiving IA triamcinolone hexacetonide) and a control group (CG, n = 20, receiving IA saline). On treatment day (T0), and at 8, 15, 30, 90 and 180 days post-treatment, weight distribution, joint range of motion, thigh girth, digital thermography, radiographic signs, synovial fluid interleukin-1 and C-reactive protein levels were evaluated. Data from four Clinical Metrology Instruments was also gathered. Results were compared Repeated Measures ANOVA, with a Huynh-Feldt correction, Paired Samples T-Test or Wilcoxon Signed Ranks Test. A Kaplan-Meier test was performed to compare both groups, with p<0.05. Results Joints were graded as mild (65%), moderate (20%) and severe (15%). Patients of both sexes, with a mean age of 6.5±2.4 years and bodyweight of 26.7±5.2kg, were included. No differences were found between groups at T0. Comparing THG to CG, weight distribution showed significant improvements in THG from 8 (p = 0.05) up to 90 days (p = 0.01). THG showed lower values during thermographic evaluation in the Lt view (p<0.01). Pain and function scores also improved from 30 to 180 days. Increasing body weight, age, and presence of caudolateral curvilinear osteophyte corresponded to worse response to treatment. Results of the Kaplan Meier test showed significant differences between groups, with THG performing better considering several evaluations and scores. Conclusion THG recorded significant improvements in weight-bearing and in with the considered CMIs, particularly pain scores. Lower thermographic values were registered in THG up to the last evaluation day. Age, sex, and radiographic findings did significantly influenced response to treatment.

Osteoarthritis is a common form of arthritis characterized by degeneration of articular cartilage and pathologic changes in surrounding bone and periarticular tissue. The disease process results in pain and dysfunction of affected joints and is a major cause of disability in the general population. Prognosis is variable; greater muscle strength, mental health, self-efficacy, social support, and aerobic exercise are associated with better outcomes. This review outlines the classification of osteoarthritis (primary and secondary) and its epidemiology and etiologic factors, including risk factors, normal articular cartilage, and pathologic changes. Diagnosis is reviewed in terms of general considerations and specific joint involvement and related complications. The differential diagnosis is discussed. Management of osteoarthritis includes nonpharmacologic measures, pharmacologic therapy, surgery, and disease-modifying or chondroprotective therapy.  This review contains 6 figures, 8 tables, and 84 references.

Background: LSTR therapy is considered as one of the most widely accepted clinical procedure for the treatment of permanent tooth with irreversible pulpitis with minimum destruction of tooth tissue Objective: To evaluate the clinical and radiographic findings of permanent tooth with irreversible pulpitis by LSTR 3Mix MP therapy and compare with conventional root canal therapy. Methods: According to inclusion and exclusion criteria, a total of 40 teeth were enrolled in this study, out of which 20 teeth treated with LSTR 3Mix MP Therapy, (Group-I) and the remaining 20 teeth treated with conventional root canal therapy (Group-2). Clinical and radiological Follow up examinations were performed at 3, 6- and 12-months interval to investigate the incidence of postoperative pain, tenderness to percussion, swelling and periodical radiolucency, collected date was analyzed by using Statistical package for Social Science (SPSS) version 17. Statistical analysis was performed by Chisquare test to assess the difference between the clinical outcome of Group 1 and 2; a value of P<0.05 was considered as statistically significant. Results: At 3 months observation period, LSTR and Conventional root canal therapy showed 100% success rate in treating teeth with irreversible pulpits; neither pain nor any tenderness on percussion or post-operative swelling was observed. Radiographic examination also revealed no sign of radiolucent area. At 6 and 12 months following the completion of the treatment, except in one case in each observation period, there results were similar to that of 3 months. One LSTR (5%) and one conventional (5%) therapy reported pain, tenderness on percussion and swelling with peripical lesion. There were no statistical differences between the two groups (p>0.05). Conclusions: It can be concluded that LSTR 3 Mix MP Therapy proved to be effective in treating teeth with irreversible pulpitis; with similar clinical and radiological outcome to conventional root canal treatment within one-year observation period.

Mortise View

Category: Ankle Introduction/Purpose: Mortise view weight-bearing radiograph is widely used for the diagnosis of osteoarthritis of ankle. Thickness of the articular cartilage cannot be accurately evaluated in the evaluation of joint space from weight-bearing radiograph, because lateral tibiotalar joint space is maintained in valgus type osteoarthritis in some cases. There are few reports on the relation between osteophyte and the articular cartilage injury. We considered that it might be possible to estimate the cartilage injury more accurately by examining osteophytes. The purpose of this study is to analyze the relationship between the location and grade of osteophytes in weight-bearing radiograph and cartilage injury in arthroscopic findings was analyzed. Methods: Twenty-one anklets of 21 patients consisted of 10 males and 10 females, with mean age of 61.4 years (31-79 years), who underwent arthroscopic surgery for osteoarthritis in our department were included. Weight-bearing radiograph were taken before surgery. Location and grade of osteophytes were evaluated using Ankle and Hindfoot Radiographic Osteoarthritis Scoring reported by Kraus et al. Arthroscopic findings were evaluated with International Cartilage Repair Society (ICRS) Grade at a total of 20 sites (9 areas of tibia and talar in tibiotalar joint, medial malleolus and lateral malleolus). The correlation between radiographic findings and arthroscopic findings were analyzed. Results: In Mortise view, strong correlations were found between lateral tibial osteophyte grade and ICRS grade of the center (talus R = 0.69, tibia R = 0.76), the central lateral (tibia R = 0.79), the posterior center (talus R = 0.72, tibia R = 0.74) and the posterior lateral of the tibiotalar joint (talus R = 0.63, tibia R = 0.76). There are moderate correlations between distal fibular osteophyte grade and ICRS grade of the medial inner (tibia R = 0.74) and the posterior medial of the tibiotalar joint (talus R = 0.61, tibia = 0.63). In lateral view, there are moderate correlations between posterior talar osteophyte grade and ICRS grade at the center of the tibiotalar joint (talus R = 0.61, tibia R = 0.60). Conclusion: From this study, there was a strong correlation between location and grade osteophyte and the articular cartilage injury. Osteoarthritis progression is caused by degeneration of the cartilage because of the joint instability, and osteophytes were formed by traction force or impaction. This study showed that local cartilage injury is thought to be related to osteophytes. By evaluating the location and size of osteophytes, the articular cartilage injury might be predicted accurately before arthroscopic surgery.

EXTERNALLY, THE HUMAN BODY appears symmetric; if a line is drawn down the middle of the body, each side appears identical. However, this is not true of the internal anatomy. For example, there is one heart, which lies in the left chest, one liver, in the right abdomen, and one stomach, in the left abdomen. The term situs refers to the position or location of an organ, specifically, the position of the atria and abdominal viscera in relation to the midline of the body.1 There are three types of situs: solitus, inversus, and ambiguous. Situs solitus refers to the normal arrangement of organs, with the right atrium, liver, gallbladder, trilobed lung, and inferior vena cava on the right side and the left atrium, stomach, spleen, bilobed lung, and descending aorta on the left side (Figures 1–3). Situs inversus totalis refers to a mirror image reversal of the normal position of the internal organs (Figures 4 and 5). 1 The incidence of situs inversus totalis is 1 in every 8,000 to 25,000 births, and the condition is most often diagnosed by radiographic examination.2Situs ambiguous, often referred to as heterotaxia, is the random arrangement of the internal organs and is associated with splenic abnormalities and congenital heart disease.3 The purpose of this column is to discuss the embryology, pathophysiology, and diagnosis of situs inversus totalis and to review a case study with radiographic findings.
