Right iliac bone pathological fracture mimicking acute appendicitis.

Am J Emerg Med 2018 Nov 17. Epub 2018 Nov 17.

Department of Surgery, University of Pamukkale, Denizli, Turkey.

Simple bone cyst (SBC) also known as unicameral bone cyst is a benign, radiolucent bone lesion that is seen commonly in childhood. These lesions are usually found incidentally although pain and swelling can be seen. The most common complication is a pathological fracture, and this is often the cause of presentation. Read More

The perspectives of politicians on tobacco control in Turkey.

Eur J Public Health 2018 Oct;28(suppl_2):17-21

World Health Organisation Regional Office for Europe, Copenhagen, Denmark.

Background: Tobacco use is a leading but preventable cause of non-communicable diseases and premature death. The legislature has a key role in setting tobacco control policies. Smoking trends are decreasing thanks to the introduction of effective tobacco control policies in Turkey and these policies may have been shaped by how politicians' interpreted social problems that were prominent during the development and implementation of tobacco regulations.

Unicameral bone cysts: Current concepts.

Ann Med Surg (Lond) 2018 Oct 28;34:43-49. Epub 2018 Jun 28.

Department of Pathology & Laboratory Medicine, Aga Khan University, Karachi, Pakistan.

Unicameral bone cysts (UBC) or simple/solitary bone cysts are benign fluid filled cavities that enlarge over time, resulting in thinning of the bone. Usually these cysts are reported in the metaphyseal areas of long bones with open physes. 85% of UBCs occur almost exclusively in children and adolescents. Read More

Comparison of three surgical treatment options for unicameral bone cysts in humerus.

J Pediatr Orthop B 2019 Jan;28(1):51-56

Department of Orthopaedic Surgery, Medical University of Graz, Graz, Austria.

Treatment of unicameral bone cysts (UBC) in the humerus with drainage screws is scarcely reported in the literature. The aim of this retrospective study was to compare drainage screws and alternative treatment methods with respect to the number of required surgical procedures to achieve sufficient UBC healing, postoperative fractures/recurrences/complications, and radiological outcome. Medical archives of two tertiary orthopedic referral centers were screened for all patients who were treated surgically for humeral UBC in the period 1991-2015 with a histologically/cytologically confirmed diagnosis.

Healing bone lesion defects using injectable CaSO /CaPO -TCP bone graft substitute compared to cancellous allograft bone chips in a canine model.

J Biomed Mater Res B Appl Biomater 2018 Apr 16. Epub 2018 Apr 16.

Department of Orthopedic Surgery, Rush University Medical Center, Chicago, Illinois.

CaSO /CaPO -TCP bone graft substitute has been shown to be effective for treatment of bone lesion defects, but its mechanical, histological, and radiographic characteristics have not been studied in direct comparison with a conventional treatment such as cancellous allograft bone. Thirteen canines had a critical-size axial defect created bilaterally into the proximal humerus. CaSO /CaPO -TCP bone graft substitute (PRO-DENSE™, Wright Medical Technology) was injected into the defect in one humerus, and an equal volume of freeze-dried cancellous allograft bone chips was placed in the contralateral defect.

*MaineOrtho, Portland, ME †The Limb Lengthening and Complex Reconstruction Service, Department of Orthopedic Surgery, Hospital for Special Surgery, Weill Medical College of Cornell University, New York, NY.

Background: Deformity and growth arrest of the humerus in children may result as sequelae of proximal humerus fractures and unicameral bone cysts, or as complications of their treatment. As approximately 80% of the growth of the humerus arises from the proximal physis, the resultant upper limb-length discrepancy can be substantial. Benefits to lengthening the shortened arm have been previously demonstrated with the use of external fixation devices. Read More

Department of Orthopaedics and Traumatology, Faculty of Medicine, Fırat University, Elazığ, Turkey.

Introduction: Curettage of the cyst and bone grafting are the most common methods used in the treatment of unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC). Recurrence of these cysts is often associated with insufficient curettage of the cyst during surgery. In this study, we aimed to evaluate the effect of insufficient curettage on recurrence in patients with UBC and ABC. Read More

Department of Orthopedic Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea.

Diaphyseal unicameral bone cysts of the long bone are generally known to originate near the growth plate and migrate from the metaphysis to the diaphysis during skeletal growth. In the case of unicameral bone cysts of diaphyseal origin, recurrence at the same location is extremely rare. We report a case of recurrence of a unicameral bone cyst in the diaphysis of the femur that developed 8 years after treatment with curettage and bone grafting. Read More

Clinic for Orthopaedics and Orthopaedic Sports Medicine, Technical University Munich, Munich, Germany.

Both unicameral bone cysts and intraosseous lipoma of the calcaneus are rare entities that are mostly diagnosed because of unspecific heel pain, pathologic fracture, or as incidental finding. Minimally invasive ossoscopy with endoscopic resection of the tumor followed by grafting can potentially minimize risks of open surgery and speed up convalescence. We present our modifications to previously described techniques of endoscopic curettage with a particular focus on intraosseous lipoma and allogenic grafting. Read More

Complete twelve month bone remodeling with a bi-phasic injectable bone substitute in benign bone tumors: a prospective pilot study.

BMC Musculoskelet Disord 2015 Nov 26;16:369. Epub 2015 Nov 26.

Department of Radiology, Poznań University of Medical Sciences, Poznan, Poland.

Background: Benign primary bone tumors are commonly treated by surgery involving bone grafts or synthetic bone void fillers. Although synthetic bone grafts may provide early mechanical support while minimizing the risk of donor-site morbidity and disease transmission, difficult handling properties and less than optimal transformation to bone have limited their use.

Methods: In a prospective series, patients with benign bone tumors were treated by minimal invasive intervention with a bi-phasic and injectable ceramic bone substitute (CERAMENT™ BONE VOID FILLER, BoneSupport, Sweden) with the hypothesis that open surgery with bone grafting might be avoided.

Unicameral bone cysts (UBCs) are benign tumor-like lesions that commonly occur in the diaphyseal or metaphyseal region of the long bones within the first 2 decades of life. Until today, the pathogenesis of UBC has been unclear, but mechanisms such as vascular occlusion or a response to trauma have been supposed. During the past decade, in particular, the genetic aspects of the development of this rare lesion have been discussed. Read More

Introduction: There is no consensus on when and how to treat unicameral bone cysts (UBCs), partly because of a lack of knowledge of the aetiology.

Purpose: To review the different treatment techniques for UBCs and to describe our results with a single injection of autogenous bone marrow (BM) mixed with demineralised bone matrix (DBM) in very young children.
