It is considered an extreme form of osteitis fibrosa cystica that occurs in the settings of persistently elevated parathyroid hormone. Case Report: This a unique lesion presented in a 48 year old male with recurrent bone pain and known End Stage Renal Disease (ESRD) on maintenance haemodialysis. The main clinical complaints were weak and painful legs and the initial presentation was after the patient collapsed at home and fractured spinal level C2. The initial assessment included blood tests and radiological imaging. CT scanning of the spine revealed a destructive lytic lesion with loss of height and architectural changes of the C2 vertebral body and cord compression. The differentials included an acute fracture, a metastatic lesion and Brown’s tumour. Further imaging with an MRI of the spine and PET-CT were performed which confirmed the above lesion and excluded metastatic disease and bone marrow infiltration.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Pycnodysostosis is an autosomal recessive disorder that manifests as osteosclerosis of the skeleton due to the defective osteoclasts mediated bone turnover. The diagnosis of this disorder is established on the basis of its characteristic features and mustbe differentially diagnosed with other bone disorders. Dental surgeons should be aware of the limitations and possible adverse oral complications such as osteomyelitis of bone in these patients. This will guide them in planning realistic treatment goals. This paper reports the clinical and radiographic features of pycnodysostosis with the great emphasis on its dentofacial characteristics. The aim of this case report is to give an insight into the etiology, pathogenesis, and differential diagnosis of this disorder and to prepare the dentists and maxillofacial surgeons to overcome the challenges in treating these patients. 1. Introduction Dental surgeons should be familiar of the classic features of this disorder in order to establish correct and timely Pycnodysostosis is a rare genetic disorder of the bone diagnosis especially when they are the first to encounter these caused by a mutation in the gene that codes the enzyme patients.

  • Management Strategy for Unicameral Bone Cyst
    Management of unicameral bone cyst MANAGEMENT STRATEGY FOR UNICAMERAL BONE CYST Chin-Yi Chuo, Yin-Chih Fu, Song-Hsiung Chien, Gau-Tyan Lin, and Gwo-Jaw Wang Department of Orthopedic Surgery, Kaohsiung Medical University Hospital, Kaohsiung, Taiwan. The management of a unicameral bone cyst varies from percutaneous needle biopsy, aspiration, and local injection of steroid, autogenous bone marrow, or demineralized bone matrix to the more invasive surgical procedures of conventional curettage and grafting (with autogenous or allogenous bone) or subtotal resection with bone grafting. The best treatment for a unicameral bone cyst is yet to be identified. Better understanding of the pathology will change the concept of management. The aim of treatment is to prevent pathologic fracture, to promote cyst healing, and to avoid cyst recurrence and re-fracture. We retrospectively reviewed 17 cases of unicameral bone cysts (12 in the humerus, 3 in the femur, 2 in the fibula) managed by conservative observation, curettage and bone grafting with open reduction and internal fixation, or continuous decompression and drainage with a cannulated screw. We suggest percutaneous cannulated screw insertion to promote cyst healing and prevent pathologic fracture. We devised a protocol for the management of unicameral bone cysts. Key Words: unicameral bone cyst, UBC, simple bone cyst, SBC, cannulated screw (Kaohsiung J Med Sci 2003;19:289–95) The unicameral bone cyst (UBC) or simple bone cyst The treatment of UBC includes: conservative (SBC) is encountered in the pediatric age group, with management to allow spontaneous healing during the majority of cases occurring in the first two decades puberty; curettage and grafting with autogenous or of life — with most around the age of 12 years [1,2].

  • The Generalized Type, However, Has Received
    THE GENERALIZED TYPE OF OSTEITIS FIBROSA CYSTICA VON RECKLINGHAUSEN'S DISEASE JOHN J. MORTON, M.D. Assistant Professor of Surgery, Yale University School of Medicine NEW HAVEN, CONN. INTRODUCTION The localized form of osteitis fibrosa, especially in its relation to the formation of bone cysts, has been very commonly recognized and com- mented upon during the last twenty years. Bloodgood,1 in numerous publications, and also Barrie,2 Silver,3 and Meyerding,4 have furnished valuable contributions to the American literature; and Elmslie5 has given a good summary of the English cases. The Germans have written at length on the subject. The generalized type, however, has received scant attention, possibly because it is not recognized; and, aside from the article by L\l=o"\tsch,6 no extensive publication has been devoted entirely to this form of the disease, although both Meyerding and Elmslie discuss the generalized cases in their papers. It seemed worth while, therefore, to report the subjoined case: first, because of the rarity of the condition, especially in the United States, and secondly, because of the possibility of correcting some of the deformities arising in this disease. At the same time, it was considered advisable to collect the reports of general types of the disease in order to find what might be learned from them. report of case History.—A man, aged 23, a lathe operator, was referred, Nov. 14, 1919, by Dr. Stanley Cox of Holyoke, Mass., complaining of bowing of the thigh bones.

Surg. 2011; 40: 106–123. # 2010 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved. Abstract. Pycnodysostosis is an extremely rare genetic osteosclerosis caused by cathepsin K deficiency. It is a human autosomal recessive genetic disorder characterized mainly by osteosclerosis of the skeleton due to decreased bone turnover. It is characterized by short stature, brachycephaly, short and stubby fingers, open cranial sutures and fontanelle, and diffuse osteosclerosis. Multiple fractures of the long bones and osteomyelitis of the jaw are frequent complications. The authors describe an 18-year-old girl with a clinical and radiological diagnosis of pycnodysostosis and the ortho-surgical treatment undertaken. Bimaxillary orthognathic surgery was carried out using rigid fixation and bone grafts. The authors recommend bimaxillary orthognathic surgery as a choice for treating the dentofacial deformities of pycnodysostosis, emphasizing the good and stable results Accepted for publication 19 July 2010 obtained in terms of facial aesthetics and occlusion.
