INTRODUCTION: Radial club hand deformity acquired post haematogenous osteomyelitis of radius bone is a very rare disease. Resulting in functional and cosmetic deficit of upper limb which is similar to congenital cases. For a long-time various surgeons attempted to reconstruct the deformity by bone grafting, plating, Ilizarov, monorail external fixator, callus distraction and so on. Keeping in mind that creating single bone forearm we proposed centralization of ulna on wrist to correct the deformity...

In this study, electrolytically deposited strongly adherent silver nanoparticles on stainless-steel (SS) implants were used for in situ osteomyelitis treatment. Samples were heat treated to enhance adhesion of silver on 316 L SS. Ex vivo studies were performed to measure silver-release profiles from the 316 L SS screws inserted in equine cadaver bones. No change in the release profiles of silver ions were observed in vitro between the implanted screws and the control. In vivo studies were performed using osteomyelitic rabbit model with 3 mm diameter silver-deposited 316 L SS pins at two different doses of silver: high and low...

BACKGROUND: Osteomyelitis is a serious disease which can be difficult to treat despite properly instituted antibiotic therapy. This appears to be related at least partly to degraded vascularisation in the osteomyelitic (OM) lesions. Studies of perfusion in OM bones are, however, few and not quantitative. Quantitative assessment of perfusion could aid in the selection of therapy. A non-invasive, quantitative way to study perfusion is dynamic [(15)O]water positron emission tomography (PET)...

Tuberculous osteomyelitis of skull is very rare, even in areas where tuberculosis is endemic. We herein describe an elderly woman who was apparently immunocompetent and presented with left frontal scalp swelling and right cervical lymphadenopathy. CT scan showed irregular bony destruction of the frontal bone. MRI revealed a large extradural, multiseptate, solid-cystic lesion with peripheral enhancement. FNAC from the lesion showed granulomas with caseation suggestive of tuberculosis. The lesion was debrided and she was started on anti-tubercular therapy...

INTRODUCTION: Infection is the commonest foot complication that arises in people with diabetes and may lead to amputation and even death. The emergence of multidrug resistant bacteria, especially in Gram negative rods, may have a negative impact on the chances of cure in these patients. AREAS COVERED: We searched the Medline and Pubmed databases for studies using the keywords 'diabetic foot infection' and 'diabetic foot osteomyelits' from 1980 to 2016. Expert commentary: Much has been done in the field of diabetic foot infection regarding pathophysiology, diagnosis and treatment...

Missense mutation in the proline-serine-threonine phosphatase-interacting protein 2 (Pstpip2) gene results in the development of spontaneous chronic bone disease characterized by bone deformity and inflammation that is reminiscent of patients with chronic multifocal osteomyelitis (cmo). Interestingly, this disease is specifically mediated by IL-1β but not IL-1α. The precise molecular pathways that promote pathogenic IL-1β production inPstpip2(cmo)mice remain unidentified. Furthermore, how IL-1β provokes inflammatory bone disease inPstpip2(cmo)mice is not known...

AIMS: Charcot neuropathic osteoarthropathy (CN) represents a complication for diabetic patients which involves a progressive alteration of the osteoarticular apparatus with high risk of amputation. The aim of the study was to assess whether the localization of CN and the extent or grading of the osteomyelitis have an influence on the rate of limb salvage and the time to recovery. METHODS: We treated a diabetic population affected by CN complicated by ulceration and widespread osteomyelitic involvement...

Osteopetrosis (OP) is a rare metabolic bone disease characterized by a generalized increase in skeletal mass. The disease is characterized by increased susceptibility to develop osteomyelitis of the jaws. We report a case of clinical and radiological progression of bimaxillary osteomyelitis in a patient with autosomal dominant OP. The patient presented non simultaneous osteomyelitis in both upper and lower jaws with time interval of 10 years. The osteomyelitis of maxilla resulted in oroantral fistula formation and required surgical closure with Bichat fat pad flap...

INTRODUCTION: Bone infections after trauma, i.e. posttraumatic osteomyelitis, pose one of the biggest problems of orthopedic surgery. Even after sufficient clinical therapy including vast debridement of infected bone and antibiotic treatment, regeneration of postinfectious bone seems to be restricted. One explanation includes the large sized defects resulting from sufficient debridement. Furthermore, it remains unclear if inflammatory processes after bone infection do affect bone regeneration...

BACKGROUND: Reinfections following implant-based cranioplasty, in the setting of previous bone flap osteomyelitis, are common and associated with significant morbidity. The timing of reconstruction following initial osteomyelitic bone flap removal remains controversial; most advocate for prolonged time intervals of approximately 6 to 12 months. Thus, the authors investigated their delayed cranioplasty outcomes following both early (between 90 and 179 days) and late (≥ 180 days) time intervals with custom craniofacial implants to determine whether timing affected outcomes and rates of reinfection...

Tuberculous lesions affecting periodontium are rare and seen as secondary infections localized to the soft tissues. With the advent of effective drug therapy, tuberculous lesions of the oral cavity have become rare. Involvement of the periodontium has seldomly been reported in the recent literature. We report a case of tuberculous osteomyelitis of mandible affecting periodontium leading to gingival recession and bone exposure in the mandibular premolar region in a 42-year-old female patient. The diagnosis was based on patient's medical and dental history, bacterial culture, clinical and radiographic examination, blood investigation, immunologic tests, histopathologic examination of the tissue specimen...

A 56-year-old woman presented with fever, pain and restriction of movement of the right temporomandibular joint. She was premorbidly diagnosed to have type 2 diabetes mellitus and rheumatoid arthritis. Local examination revealed a poorly demarcated severely tender, erythematous swelling in the right preauricular region. All haematological and biochemical investigations were within normal limits. MRI of the neck revealed the presence of a masticator space infection with intramuscular abscess involving the masseter and the temporalis muscles along with intracranial extension...

We report a case of a 46-year-old man with fever, hypotension and arthralgias of the ankles and knees after brain surgery for a pituitary tumour causing Cushing's disease. Blood and urine cultures isolated Serratia marcescens; antibiotic susceptibility testing showed sensitivity to piperacillin-tazobactan and ciprofloxacin. Articular MRI showed inflammation and necrosis of both knees and ankles, and left hip and right elbow (compatible with osteomyelitis). Culture of an ankle abscess on the ankle joint was positive for Serratia marcescens...

Infection spreading in the skeletal system leading to osteomyelitis can be prevented by the prolonged administration of antibiotics in high doses. However systemic antibiotherapy, besides its inconvenience and often low efficacy, provokes numerous side effects. Thus, we formulated a new injectable nanoparticle-loaded system for the local delivery of vancomycin (Vanc) applied in a minimally-invasive way. Vanc was encapsulated in poly(L-lactide-co-glycolide) nanoparticles (NPs) by double-emulsification. The size (258 ± 11 nm), polydispersity index (0...
