Objective. To determine the interobserver and intraobserver reliabilities of the Enneking Classification system in staging benign bone tumors. Methods. Photographs of traditional plain radiographs of 65 histologically benign tumors from the PGH Department of Orthopedics Tumor Registry were used in the study. Nine Orthopedic surgeons (three consultants, one fellow, and five senior residents) staged the tumors using the Enneking Classification based on radiographic tumor-host margins. The photographs were sent to the surgeons twice (batch 1 and 2), three months apart, for staging. The Fleiss and Cohen kappa statistics were used to determine interobserver and intraobserver reliabilities, respectively. This is a pilot study. Results. There was only fair interobserver reliability of the Enneking Classification staging with Fleiss kappa of 0.38 and 0.26 for batches 1 and 2, respectively. Also, there was only moderate intraobserver reliability (Cohen kappa 0.48) for the staging. Moreover, there was also a relatively low intraobserver percent agreement (67%) among raters. In both reliabilities, the consultants/fellow group consistently showed better interobserver and intraobserver reliabilities compared to the residents. Conclusion. The Enneking Classification in staging benign bone tumors had relatively low interobserver and intraobserver reliabilities. There was also a tendency of experienced orthopedic tumor consultants and senior residents to stage the same radiograph differently upon repeat testing.

Objective : The aim of this study is to assess the intra- and interobserver concordance of SINS, Harrington, Tokuhashi and Tomita scores among general orthopedic surgeons and spine surgeons with experience above 5 and 10 years in the evaluation of patients with spinal metastasis. Methods : Twenty cases of patients with metastatic lesion of the spine were presented to 10 examiners and the scores aforementioned have been applied. After six weeks, the cases were reintroduced in a different order and data were analyzed. Results : The intraobserver reliability showed better agreement in SINS score among examiners with less experience and Harrington and Tomita scores among those who had more than 10-year experience. The interobserver reliability of the examiners of the group with over 10-year experience showed higher precision when using these scores, especially Harrington and Tomita. The SINS score was the choice for daily practice and was able to modify the management more often. Conclusions : This study demonstrated that the use of predictive scores of instability, Harrington, and prognosis, Tomita, had a higher intra- and interobserver reliability particularly among spine surgeons with experience above 10 years.

Tumors Of The Hand

Background: Benign tumors of the hand present in a wide array of histological subtypes and compose most of the bony tissue tumors in the hand. This study evaluates the characteristics and treatment of benign bone tumors in light of one institution’s experience. Methods: Histologically confirmed benign tumors of the hand were retrospectively identified using International Classification of Diseases codes from 1992 to 2015. A medical chart review was conducted to collect patient characteristics and tumor epidemiology and treatment. Results: A total of 155 benign bone tumors were identified. The median age of patients at the time of surgery was 39.9 ± 12.8 years. All bone tumors were located in the digits, and most were treated by intralesional curettage (n = 118, 76%). Pathologic fractures occurred in 79 bone tumors (51%). Conclusion: Enchondromas (n = 118, 76%) were the most common bone tumor in this series, whereas giant cell tumors were the most destructive and also had the highest recurrence rate (40%). Awareness of tumor features may help physicians with diagnosis, and awareness of recurrence rates is important when counseling patients.

This is a prospective study done at Al wasity teaching hospital for reconstructive surgeries in Bagdad in a period from November 2014 to April 2017, using a Total of 119 samples of primary bone tumors which were diagnosed both histopathologically and radiologically. The main objectives of this study was to make a comparison between benign and malignant bone tumors. Immunohistochemical staining was done to confirm the diagnosis of primary malignant bone tumors and the proliferative index of them were carefully evaluated. Out of 119 samples of primary bone tumors used in this study ,100 (84%) were benign and borderline(osteoclastoma) and 19(16%) were malignant, the mean age for benign tumors was lower than the mean age for primary malignant one and both frequently present in the 2nd decade of life, male to female ratio for benign bone tumors was 3\2 and 8.5\1 for primary malignant one, femure was the most common location for benign bone tumors while tibia was the most common bone affected by primary malignant bone tumors. the study also showed that the most common benign bone tumors were osteochondromas(67%) and most common primary malignant bone tumors were osteosarcomas(52.63%),thus this study rise a conclusion that in general, primary bone tumors were mainly benign, occurred predominantly in the second decade of life with a male preponderance

Hematogenous Osteomyelitis

Objective. This study aimed to evaluate the inter- and intraobserver reliability of the Penny and Beit CURE radiologic classifications of pediatric patients with Chronic Hematogenous Osteomyelitis (CHOM) in the Philippine General Hospital (PGH). Methods. Thirty-four pre-operative radiographs of PGH pediatric patients with CHOM were classified by seven orthopedic surgeons using both Penny and Beit CURE Classification systems. Two sets of radiographs were sent to the surgeons twice, four weeks apart, to classify. The Fleiss and Cohen κ statistics were used to determine inter- and intraobserver reliabilities, respectively. Results. The Penny Classification had a slight to fair interobserver reliability (Fleiss κ = 0.17 and 0.24) and a fair intraobserver reliability (Cohen κ =0.35) with a 49.58% average intraobserver agreement. The interobserver reliability when including all Beit CURE classification subtypes was fair (κ = 0.28 and 0.31). This improved to moderate (κ = 0.41 and 0.54) when using only the four main types of the Beit CURE classification with a 77.31% intraobserver agreement. Conclusion. The Beit CURE classification for pediatric CHOM had higher inter- and intraobserver agreement rates than the Penny classification. Further improvement in reliability can be made by combining B2 and B3 subtypes under the Beit CURE classification.

Picture Archiving And Communication

Background: The initial diagnosis of capitellum osteochondritis dissecans (OCD) is typically confirmed using standard anteroposterior (AP) and lateral elbow radiographs, despite low sensitivity, which is approximately 44-47%. An AP image of the elbow in 45° of flexion has been suggested to increase diagnostic accuracy. Purpose: To assess the diagnostic performance, inter- and intra-observer reliability, and confidence level for identifying capitellum OCD using plain radiographs (AP, lateral, and 45° flexion AP) in pediatric and adolescent patients. Methods: This was a retrospective study including pediatric and adolescent patients with capitellum OCD and a healthy control group. Independent clinicians were blinded to the official radiologists’ reports and reviewed images on a picture archiving and communication system on two separate occasions 1 week apart. A 5-point Likert scale was used to assess the clinicians’ level of confidence (1-not at all confident; 5-very confident). Inter- and intraobserver reliability was determined using kappa statistics. Results: The study included 28 elbows (24 patients) with a mean age of 12.5 ± 2.0 years. 64.3% were female. There were no differences in age ( P = 0.18), sex ( P = 0.62), or laterality ( P = 1.0) between the two groups. There were marked variations in the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for each of the following views: AP: Sensitivity 85.1; Specificity 89.3; PPV 88.8; NPV 85.7; accuracy 87.2. Lateral: Sensitivity 73.2; Specificity 91.7; PPV 89.8; NPV 77.4; accuracy 82.4. 45° flexion AP: Sensitivity 91.7; Specificity 91.1; PPV 91.1; NPV 91.6; accuracy 91.4. Standard radiographs (AP and lateral views) failed to diagnose capitellum OCD in 4.8% of cases. The sensitivity of the three combined views was 100%. Confidence levels in the clinicians’ diagnostic assessments were similar for each view (AP, 4.0; lateral, 4.0; and 45° flexion AP, 4.1). Interobserver reliability was substantial for AP and lateral views (k=0.65 and k=0.60, respectively) but highest for the 45° flexion AP radiographs (k=0.72). Intraobserver reliability for all views was moderate to perfect (k=0.52 to 0.93). Conclusion: The 45° flexion AP view can detect capitellum OCD with excellent accuracy, a high level of confidence, and substantial interobserver agreement. When added to standard AP and lateral radiographs, capitellum OCD can be diagnosed in 100% of cases.

Breed predispositions to canine digital neoplasms are well known. However, there is currently no statistical analysis identifying the least affected breeds. To this end, 2912 canine amputated digits submitted from 2014–2019 to the Laboklin GmbH & Co. KG for routine diagnostics were statistically analyzed. The study population consisted of 155 different breeds (most common: 634 Mongrels, 411 Schnauzers, 197 Labrador Retrievers, 93 Golden Retrievers). Non-neoplastic processes were present in 1246 (43%), tumor-like lesions in 138 (5%), and neoplasms in 1528 cases (52%). Benign tumors (n = 335) were characterized by 217 subungual keratoacanthomas, 36 histiocytomas, 35 plasmacytomas, 16 papillomas, 12 melanocytomas, 9 sebaceous gland tumors, 6 lipomas, and 4 bone tumors. Malignant neoplasms (n = 1193) included 758 squamous cell carcinomas (SCC), 196 malignant melanomas (MM), 76 soft tissue sarcomas, 52 mast cell tumors, 37 non-specified sarcomas, 29 anaplastic neoplasms, 24 carcinomas, 20 bone tumors, and 1 histiocytic sarcoma. Predisposed breeds for SCC included the Schnauzer (log OR = 2.61), Briard (log OR = 1.78), Rottweiler (log OR = 1.54), Poodle (log OR = 1.40), and Dachshund (log OR = 1.30). Jack Russell Terriers (log OR = −2.95) were significantly less affected by SCC than Mongrels. Acral MM were significantly more frequent in Rottweilers (log OR = 1.88) and Labrador Retrievers (log OR = 1.09). In contrast, Dachshunds (log OR = −2.17), Jack Russell Terriers (log OR = −1.88), and Rhodesian Ridgebacks (log OR = −1.88) were rarely affected. This contrasted with the well-known predisposition of Dachshunds and Rhodesian Ridgebacks to oral and cutaneous melanocytic neoplasms. Further studies are needed to explain the underlying reasons for breed predisposition or “resistance” to the development of specific acral tumors and/or other sites.

AbstractBackground: CERAMENT™|BONE VOID FILLER is an injectable and moldable ceramic bone substitute material intended for bone voids. The material consists of hydroxyapatite and calcium sulfate hemihydrate. The aim of this study is to present the first long-term results following open curettage of benign bone tumors and tumor-like lesions and void filling with this novel injectable and synthetic bone graft. Methods: Thirty three patients were enrolled into the study between June 2013 and October 2014 .Totally, we treated 24 women and 9 men with a median age of 47 years (range: 22-74). All patients suffered from primary musculoskeletal system disorders (enchondroma 63,6%, giant cell tumor 18%, aneurysmal bone cyst 9%, fibrous dysplasia 9%, Gaucher disease 3%). We performed curettage of pathological lesions, then the bone substitute was administered by means of needle to the void. Results: The average follow-up was 13 months (range: 2-13 months, median 10 months). No metastasis or recurrence had been detected. We received significant clinical improvement relating to VAS, MSTS, and oncological results. Conclusions: The results of our study report that CERAMENT can be successfully used as a bone substitute in patients with various bone diseases, as well as benign bone tumors. CERAMENT can provide an effective and long-term solution for reconstructive procedures following curettage of bone tumors and tumor like lesions.
