The ossification level of tarsal bones and the distal end of the tibia in human foetuses of both sexes from 4 to 9 month gestational age was estimated. Our results show that ossification of the cartilaginous model tarsal bones begins from 6 to 7 months of the gestational age with the appearance of a single ossification point in the ankle bone and two ossification points in the heel bone with th...

Of 20 children who underwent cochlear implantation for profound sensorineural hearing loss secondary to bacterial meningitis, 14 had round-window and cochlear ossification at surgery. Preoperative polytomography demonstrated ossification in 11 of these. The incidence of ossification was highest after meningitis secondary to pneumococcal pneumonia. In only one of four children with severe ossifi...

Clinical symptoms of stylohyoid chain ossification vary from ear pain to dysphagia. It is usually diagnosed coincidentally. Localized ossification of the chain is common, whereas diffuse ossification is rare. Herein, a case with bilateral diffuse stylohyoid chain ossification diagnosed with computed tomography, which was performed in order to evaluate the patient's temporomandibular joint pain,...

We evaluated the incidence of heterotopic ossification following total ankle replacement to determine whether the degree of ossification was associated with the clinical outcome. We evaluated 90 ankles in 81 consecutive patients who underwent total ankle replacement, and heterotopic ossification was assessed according to proportional involvement of the ankle joint. Correlation analysis was used...

The aim of our study was to evaluate the utility and diagnostic accuracy of the ossification grade of medial clavicular epiphysis on chest radiographs for identifying Korean adolescents and young adults under the age of majority. Overall, 1,151 patients (age, 16-30) without any systemic disease and who underwent chest radiography were included for ossification grading. Two radiologists independ...

We observed the osteological development of larval and juvenile red spotted grouper (Epinephelus akaara) in order to generate data for the assessment of skeletal deformities and to inform phylogenetic systematics research. Larvae and juveniles were obtained from a aquafarm in Muan-gun, Jeolla-namdo Province, Korea. The average water temperature at the time of breeding was 23.0°C and average wat...

fibrodysplasia ossificans progressiva (fop) is a rare hereditary connective tissue disease characterized by the progressive ectopic ossification of ligaments, tendons, and facial and skeletal muscles throughout life. symptoms begin in childhood as localized soft tissue swellings. immobility and articular dysfunction appear with involvement of the spine and proximal extremities. the temporomandi...

BACKGROUND Heterotopic ossification around the elbow can result in pain, loss of motion, and impaired function. We hypothesized that a single dose of radiation therapy could be administered safely and acutely after elbow trauma, could decrease the number of elbows that would require surgical excision of heterotopic ossification, and might improve clinical results. METHODS A prospective random...

BACKGROUND Even though heterotopic ossification (HO) is most often asymptomatic in patients after total hip replacement (THR), it remains a serious problem in orthopaedics as it is observed in nearly all operated patients. MATERIALS AND METHODS The article presents a pre- and post-operative retrospective analysis of heterotopic ossification based on radiographic evidence. The study involved 7...

The bones of the posterior portion of the mammalian skull often exhibit incomplete ossification of the joints between the bones at the time of birth, with complete ossification at some point after birth. The sequence of ossification of these joints in mysticetes can be used to characterize the relative age in the calf and early juvenile ontogenetic stages. This study examined occipital joints o...
