A unicameral bone cyst, also known as a simple bone cyst, is a cavity filled with a yellow-colored fluid. It is considered to be benign since it does not spread beyond the bone. Unicameral bone cysts can be classified into two categories: active and latent. An active cyst is adjacent to the epiphyseal plate and tends to grow until it fills the entire diaphysis, the shaft, of the bone; depending on the invasiveness of the cyst, it can cause a pathological fracture or even destroy the epiphyseal plate leading to the permanent shortening of the bone. A latent cyst is located away from the epiphyseal plate and is more likely to heal with treatment. It is typically diagnosed in children from the aged 5 to 15. Although unicameral bone cysts can form in any bone structure, it is predominantly found in the proximal humerus and proximal femur; additionally, it affects males twice as often as females. Most unicameral bone cysts do not cause any symptoms and are discovered as accidental findings on ...
BACKGROUND: The purpose of this study was to compare the outcome of percutaneous curettage with intralesional injection of methylprednisolone and bone marrow for unicameral bone cysts (UBCs). METHODS: This was a retrospective review of 46 children and adolescents with UBC treated with autologous bone marrow injection, methylprednisolone acetate injection or percutaneous curettage alone. Inclusion criteria were a radiological diagnosis of UBC and at least 24 months follow-up from the last procedure. Healing was determined using Neer/Cole 4-grades rating scale. RESULTS: The 3 treatment groups were comparable with regard to age, sex, location of the cyst, and the number of procedures undertaken. At 2 years follow-up, the proportion of patients with satisfactory healing (Neer/Cole grades I and II) was greatest among those who underwent percutaneous curettage (70%) compared with bone marrow injection (21%) and methylprednisolone acetate injection (41%) (P = 0.03). We found no association between healing and

Subchondral bone cysts are a widely observed, but poorly understood, feature in patients with knee osteoarthritis (OA). Clinical quantitative computed tomography (QCT) has the potential to characterize cysts in vivo but it is unclear which specific cyst parameters (e.g., number, size) are associated with clinical signs of OA, such as disease severity or pain. The objective of this study was to use QCT-based image-processing techniques to characterize subchondral tibial cysts in patients with knee OA and to explore relationships between proximal tibial subchondral cyst parameters and subchondral bone density as well as clinical characteristics of OA (alignment, joint space narrowing (JSN), OA severity, pain) in patients with knee OA. The preoperative knee of 42 knee arthroplasty patients was scanned using QCT. Patient characteristics were obtained, including OA severity, knee pain, JSN, and alignment. We used 3D image processing techniques to obtain cyst parameters including: cyst number, cyst number per

Subchondral cystic lesions (SCL), sometimes referred to as subchondral bone cysts (SBC) or subchondral lucencies, occur in the medial femoral condyle (MFC) of horses and can cause lameness. They are more common in horses ≤ 2 years of age, but can occur in older horses. The causes of SCL are not well understood, however, trauma and osteochondrosis are most commonly implicated. Radiographs of young horses that develop SCLs indicate a progression from sclerosis to MFC flattening, and then a defect (SCL) that enlarges. Treatments are directed at reducing local inflammation and promoting bone and cartilage healing, with approximately 50-75% of horses becoming sound enough for work. However, bone healing after surgery is inconsistent, occurring in ,20% of patients. Recently, a treatment of MFC SCL using a lag screw was reported to improve the rate of lameness resolution and is the first study to report significant and consistent bone healing. This suggests a biomechanical approach can improve the ...
This retrospective study evaluated the efficacy of minimally invasive surgery to control cyst progression for active unicameral bone cysts (AUBC) by intracystic methylprednisolone injection, percutaneous curettage, and autogenous bone marrow grafting. From May 2010 to May 2017, patients diagnosed with AUBC who underwent percutaneous double-needle intracystic methylprednisolone injection, percutaneous curettage, and autogenous bone marrow grafting were retrospectively reviewed. Recurrence was defined by modified Neer scale score. Patients were followed up regularly, and previous imaging findings were compared to evaluate treatment efficacy. The 26 patients (17 boys, 9 girls, mean age, 9.4 ± 3.1 years) were followed up for a mean 45.1 months (range, 24-82 months). Follow-up consisted of clinical evaluation and radiographic review. Twenty patients (77%) achieved latent disease stage after the first treatment, while six (23%) achieved it after the second treatment. Postoperative pathological fracture
A unicameral bone cyst (UBC) is a common, benign, fluid-filled lesion found almost exclusively in children. Much has been written about the diagnosis and management of these lesions, and evidence of a variety of successful treatment strategies can be found in the literature.
When encountering a radiologically benign lucent bone lesion in a child, a simple bone cyst is a reasonable diagnostic consideration. Simple or unicameral bone cysts are expansile, serous-fluid-containing defects, that are not true neoplasms. Peak age ranges between 3 and 14 years in 80% of cases.

In phycology, a pneumatocyst is a floating structure that contains gas found on brown seaweed. A seaweeds thallus may have more than one. They provide buoyancy to lift the blades toward the surface, allowing them to receive more sunlight for photosynthesis. The proportion of gases in the pneumatocysts varies depending on the physiological status of the alga and the partial pressure of gases in the surrounding air or water. The pneumatocyst can hold O2, CO2, N2, and CO. Thiel, M.; L. Gutow (2005). "The Ecology of rafting in the marine environment". Oceanography and Marine Biology: An Annual Review.

Many bone cysts will eventually heal without the need for treatment and wont cause long-term problems - particularly unicameral bone cysts in children, which will usually disappear by the time they stop growing.. If a bone cyst does not get better, or if treatment is recommended to help reduce the risk of a fracture, several options may be available.. For example, steroid medication can be injected into the bone to encourage the cyst to heal. If this doesnt help, surgery may be needed to drain the fluid and fill the hole with chips of bone.. There is a significant chance of the cyst recurring after treatment, so you may need to have regular X-rays for a few years afterwards to look for signs of the condition returning..

Intraosseous ganglion is rarely associated with clinical symptoms because instances of extraosseous extensions are rare; the periosteum and the cortex of the bone represent a substantial physical barrier for intraosseous extensions of soft tissue lesions to intrude into bone. However, we observed a case of a symptomatic intraosseous ganglion located in the articular capsule of the hip in the inferomedial femoral neck. A 21-year-old woman complained of persistent mild pain and discomfort in the left groin for 18 months. Further, she complained about involuntary movements such as external rotation of the hip during full flexion and adduction and inability to kneel down, as well as discomfort during exercise such as yoga. Radiography and computed tomography implied the presence of an intraosseous ganglion in the inferomedial femoral neck. Using an image intensifier, we excised the lesion arthroscopically. The patients symptoms resolved immediately after surgery. This report describes a case of ...

Compared to other stemcell sources cord blood (CB) is easier and safer to procure, has no donor attrition, a limitless supply, reduced viral transmission, less acute & chronic GVHD, is rich in hematopoietic progenitor cells, and immaturity of T-cell-mediated immunity. CB has delayed neutrophil and platelet engraftment, a prolonged immune reconstitution, uncertain graft-vs-tumor activity, and cell doses from single CB units (U) are a limiting factor for larger recipients Using the intravenous route (IV), a close match between the patient (pts) and the donor or CBU can improve a pts outcome after transplant. Even though a closely matched CBU is preferred, the studies suggest the match may not have to be as close as is needed for marrow or peripheral blood transplants If one has an uncommon tissue type, the doctor may not find a closely matched adult donor and a CBU may be an option, are stored and ready to use.

In one study in Quebec, each horses racing performance at two years of age was related to the radiographic lesions diagnosed at approximately 17 months of age and before training (there were two generations of 41 and 32 yearlings, respectively); five stallions and 46 mares, were also radiographed). No complete clinical examinations or lameness diagnoses were made. Radiographic lesions were found in 31 (25%) of the horses (8 adults and 23 yearlings), of which 60% had a single problem, and 40% had between two and four radiographic problems. Subchondral bone cysts were detected in 14 (11.3%) horses (6 carpus, 5 fetlock, 4 pastern, 2 hock, and 2 stifle). Juvenile osteoarthritis lesions were diagnosed 78 times in 35 (47.9%) of the yearlings (40 pastern, 13 fetlock, 11 carpus, 8 coffin, 6 hock) based primarily on the basis of osteophytes. Sesamoiditis was also diagnosed in yearlings. The average winnings and number of starts were compared between radiographically normal horses, the OCD or subchondral ...

According to the World Health Organization (WHO), the classification of odontogenic tumor keeps changing [6, 7]. Cementoma, as a common benign odontogenic tumor, generally occurs in the maxilla and the mandible [4]. Cementoma occurring in the long bone is the rare bone lesion [1, 8]. There is a controversy in the cementoma located in the long bones, due to the reason that many authors do not accept the existence of true cementum outside the gnathic region. Mirra et al. [8] thought cementoma of long bone is merely a form of simple bone cysts. In 1985, Adler [2] found there was calcified cementum-like material accompanied by few fibroblasts in the solitary bone cysts. They thought cementoma was originally bone cysts which calcified steadily with age [2]. This tumor in the long bone has been reported in three separate types of lesions [3], including a simple bone cyst with associated cementum-like particles in the cyst lining, calcified cementum such as is present in our patient, cementifying ...
Aneurysmal bone cysts (ABCs), a rare distinct pathologic entity, is an intraosseous, osteolytic lesion seen as locally destructive, rapidly expansile which has been reported to affect mainly the metaphyseal region of long bones and vertebrae. Aneurysmal bone cysts secondary to ossifying fibroma remains a relatively uncommon finding in the facial bones, and it is extremely rare with only very few cases reported in the mandible. This case report reveals one such, in a 42 year old lady, who presented with a solitary swelling of the right mandible, with obliterated vestibular depth, which showed Central Ossifying Fibroma as a pre-existing lesion, transforming into Aneurysmal Bone Cyst. Such rare entities are usually misdiagnosed and this gradually results in inappropriate treatment planning and poor prognosis.. ...
An intraosseous ganglion cyst is an uncommon, benign cystic bone lesion occurring in close association with an articular surface (5). However, intraosseous ganglion cysts of the fibula are very uncommon.. Male patients have a minor preponderance for this disease. The age distribution is very wide (18-86 years according to the literature) and the majority of the patients are middle-aged (6). The aetiology and pathogenesis of intraosseous ganglions remain unknown, although there are several theories on the pathogenesis of the cyst (7,8).. Wei et al reported several cases supporting this type of theory (8). Schajowicz et al (7) hypothesized it may be caused by intramedullary metaplasia followed by mucoid degeneration with intraosseous cyst formation. Altered mechanical stress may also lead to intramedullary vascular disturbance and aseptic necrosis. Subsequently, the revitalization of these necrotic areas leads to fibroblastic proliferation and mucoid degeneration. Crane hypothesized the lesion may ...

There are several pathophysiological causes for the ischemia that has been postulated as the etiological basis for avascular necrosis. One involves an acceleration of the bone degradation versus synthesis.6 In the course of avascular necrosis, however, the healing process is usually ineffective and the bone and subsequent soft tissues break down faster than the body can repair them. If left untreated, the disease progresses, the bone collapses and the joint surface breaks down, leading to pain and arthritis.. Avascular necrosis occurs when the blood supply to the talus is compromised and leads to ischemic bone death. About 60% of the talus is covered by cartilage, limiting the area for blood vessels to penetrate.7 The blood supply to the talus enters the bone through the capsular and ligamentous attachments.8 The vascular supply to the talar dome is an end-artery system, with blood vessels entering from the talar neck and plantar talar body. Circulation to the talus is supplied by the posterior ...

Osteoarthritis in animals is just as common as that in humans. Recent research indicates that osteoarthritis is the result of a viscous cycle initiated by damage to bone underneath the cartilage. By filling those damaged areas and accompanying subchondral cysts with the bone substitute, the progression of the disease may hopefully be stopped. The new bone substitute is well-suited for healing bone damage underneath the cartilage in animals. It can also be used as a bone cement to secure bone implants in place in animal complete joint replacement surgeries. Currently, it is very difficult for surgeons to fixate bone implants due to the small size of animal bones. The major bone cements in the market Calcium Phosphate and PMMA are too viscous to be injected through a needle of such a small gauge size. Novuss product has a lower viscosity which can fit the purpose. The teams next step is to develop a new cartilage substitute that can be used in conjunction with the bone substitute so as to ...
Dr. Michalski responded: ABC. Aneurysmal bone cysts treated surgically heal in approximately 6 weeks--depending on the personality and location and size of the cyst. If it is fractured/displaced it may take somewhat longer.
Chronic CPP crystal inflammatory arthritis: Chronic inflammatory oligoarthritis or polyarthritis associated with CPPD. Patients have occasional systemic upset with elevation of CRP and ESR and superimposed flares with characteristics of crystal inflammation (see above). Differential considerations include rheumatoid arthritis and other chronic inflammatory joint diseases in older adults. Imaging findings are similar to those of osteoarthritis, but the dirstribution within the joint is different, with CPPD affecting non-weight-bearing surfaces of joints. It is also usually bilateral and symmetric. Synovial inflammation and joint effusions can also be seen. Osteophytes and osteochondral bodies are commonly present. Subchondral cysts are more prominent than in osteoarthritis, and may form before cartilage loss is radiographically evident. Risk factors for calcium pyrophosphate arthropathy are aging, osteoarthritis, previous joint trauma, metabolic diseases (e.g., the four Hs: hemochromatosis, ...
An os acromiale must be mentioned in the report, because in patients who are considered for subacromial decompression, the removal of the acromion distal to the synchondrosis may further destabilize the synchondrosis and allow for even greater mobility of the os acromiale after surgery and worsening of the impingement (4).

USP6 rearrangement is the most common genetic abnormality in primary aneurysmal bone cyst, and SS18 rearrangement has not been previously described in any type of tumor where synovial sarcoma was excluded from the differential diagnosis. We report a case of solid aneurysmal bone cyst in which fluorescence in situ hybridization (FISH) analysis indicated rearrangements of both USP6 and SS18, but histologic features were consistent with aneurysmal bone cyst throughout the lesion. Reverse-transcription polymerase chain reaction (RT-PCR) for the SS18-SSX1 and SS18-SSX2 translocations, identity testing, and SS18 FISH were performed on cytogenetic monolayer cultures and formalin-fixed paraffin-embedded (FFPE) tissue. Genomic microarray, FISH, and immunohistochemistry were performed on follow-up studies of the FFPE specimen. The karyotype was 45,X,add(X)(p11.2),add(4)(q13),add(8)(p21),-13,add(17)(p11.2),add(18)(q11.2) in all 20 cells analyzed from monolayer cultures. The karyotype showed no ...
