Pediatric Scaphoid Fracture Associated with Osteopetrosis: A Case Report.

JBJS Case Connect 2021 Apr 13;11(2). Epub 2021 Apr 13.

Department of Orthopaedic Surgery, Maimonides Medical Center, Brooklyn, New York.

Case: A 12-year-old boy with osteopetrosis sustained a scaphoid waist fracture, which has not previously been reported with this condition. Healing was successfully achieved with percutaneous cannulated compression screw fixation, albeit with prolonged healing as is typical for this condition.

Conclusion: A lack of osteoclastic remodeling predisposes patients with osteopetrosis to fractures, commonly in long bones. Read More

Excision of fibrous band and application of tension band plating in focal fibrocartilaginous dysplasia: A case report and literature review.

Acta Orthop Traumatol Turc 2021 Mar;55(2):184-188

Department of Orthopaedics and Traumatology, Hacettepe University, School of Medicine, Ankara, Turkey.

Focal fibrocartilaginous dysplasia (FFCD) is a rare disease that can cause angular deformities of long bones. The common pathologic finding is a thick fibrotic band extending from epiphysis to metaphysis on one side of the bone. The tethering effect of the fibrotic band around the growth plate is thought to be the main etiology for the development and progression of the deformity. Read More

Radiological and histopathological features of short rib‑polydactyly syndrome type III and identification of two novel variants.

Mol Med Rep 2021 Jun 13;23(6). Epub 2021 Apr 13.

Department of Gynecology and Obstetrics, Key Laboratory of Maternal‑Fetal Medicine of Liaoning Province, Key Laboratory of Obstetrics and Gynecology of Higher Education of Liaoning Province, Liaoning Centre for Prenatal Diagnosis, Research Center of China Medical University Birth Cohort, Shengjing Hospital of China Medical University, Shenyang, Liaoning 110004, P.R. China.

Short rib‑polydactyly syndrome type III (SRPS3) is a lethal perinatal skeletal disorder consisting of polydactyly and multi‑system organ abnormalities. To further assess the pathogenicity of two pairs of compound heterozygotes and to search for novel molecular etiology, X‑rays and hematoxylin and eosin staining were conducted in three cases: Two retrospective samples and a newly identified patient with SRPS3. In addition, next‑generation sequencing was used to evaluate a fetus with SRPS3. Read More

Radiological Assessment of Giant Cell Tumour of Bone in the Sacrum: From Diagnosis to Treatment Response Evaluation.

Curr Med Imaging 2021 Apr 6. Epub 2021 Apr 6.

Department of Orthopaedic Surgery, IRCCS Rizzoli, Bologna. Italy.

Giant cell tumour of bone (GCTB) typically occurs in young adults from 20-40 years old. Although the majority of lesions are located in the epi-metaphyses of the long bones, approximately one third of tumours is located in the axial skeleton, of which only 4% in the sacrum. Sacral tumours tend to be large at the time of presentation, and they present with aggressive features such as marked cortical destruction and an associated soft tissue component. Read More

Osteoblastoma of the Distal Radius.

J Hand Surg Am 2021 Apr 8. Epub 2021 Apr 8.

Department of Pathology, Maulana Azad Medical College and Associated Lok Nayak Hospital, New Delhi, India.

Osteoblastomas are rare, benign, bone-forming neoplasms that represent less than 1% of all bone tumors and occur mostly in people aged 10 to 30 years. In long bones, the metadiaphyseal region tends to be most commonly affected. However, to the best of our knowledge, only 11 cases have been reported to occur in the distal radius. Read More

Single Versus Multi-channel Dispersion Analysis of Ultrasonic Guided Waves Propagating in Long Bones.

Ultrason Imaging 2021 Apr 12:1617346211006660. Epub 2021 Apr 12.

Department of Electronic Engineering, Fudan University, Shanghai, China.

Ultrasonic guided wave techniques have been applied to characterize cortical bone for osteoporosis assessment. Compared with the current gold-standard X-ray-based diagnostic methods, ultrasound-based techniques pose some advantages such as compactness, low cost, lack of ionizing radiation, and their ability to detect the mechanical properties of the cortex. Axial transmission technique with a source-receiver offset is employed to acquire the ultrasound data. Read More

Am J Med Genet A 2021 Apr 10. Epub 2021 Apr 10.

Department of Pediatric Genetics, Cerrahpasa Medical School, Istanbul University-Cerrahpasa, Istanbul, Turkey.

Dysosteosclerosis is a group of sclerosing bone dysplasia characterized by short stature, increased bone fragility, osteosclerosis, and platyspondyly. It is a genetically heterogeneous disorder caused by biallelic mutations in the SLC29A3, TNFRSF11A, TCIRG1, and CSF1R genes. To date, four dysosteosclerosis patients with SLC29A3 mutations have been reported. Read More

Inter-Implant Papilla Reconstruction via a Bone and Soft Tissue Augmentation: A Case Report with a Long-Term Follow-up.

Int J Periodontics Restorative Dent 2021 Nov-Dec;41(2):169-175

Implant-related esthetic demands have increased tremendously in recent years. The presence of shallow papillae or open interproximal spaces (black triangles) are some of the most troubling dilemmas in dentistry. Among the many factors associated with the presence of papilla or papilla height, the interproximal bone is one of the main factors dictating the presence of an adequate papilla between implants.

Epiphyseal Ewing Sarcoma in a skeletally mature patient: A case report and review of the literature.

Radiol Case Rep 2021 May 19;16(5):1191-1197. Epub 2021 Mar 19.

Diagnostic, Molecular and Interventional Radiology, Mount Sinai Health System, 1468 Madison Ave, New York, NY, 10029, USA.

While Ewing sarcoma of bone is the second most common primary osseous malignancy in childhood where it typically involves the diaphysis or metadiaphyses of long bones of skeletally immature patients, primary epiphyseal involvement of the long bone in skeletally mature patients is rare with no cases reported in the literature to our knowledge, rendering this case the first of its kind. We present the first case of primary Ewing Sarcoma of the epiphyses of the long bones in a skeletally mature 20-year-old male patient. The patient initially presented with left knee stiffness and pain that was empirically treated with non-steroidal anti-inflammatory medications. Read More
