AI Article Synopsis

  • - A 74-year-old man was found to have an unusual ossified soft tissue mass in his leg, diagnosed as calcific myonecrosis, a rare condition with calcified growths.
  • - The differential diagnosis for this condition includes myositis ossificans and various sarcomas that can cause calcification outside of bones, such as extra-skeletal osteosarcoma and Ewing's sarcoma.
  • - The diagnosis was confirmed through imaging techniques that ruled out soft tissue sarcomas, combined with typical disease progression and radiopathological characteristics.

Article Abstract

We report the clinico radiological presentation of an unusual case of an ossified soft tissue mass in the leg in a 74-year-old man. Calcific myonecrosis is a rare soft tissue condition characterized by calcified mass within a compartment. Differential diagnosis of myonecrosis include myositis ossificans and sarcomas with propensity for extra-osseous calcification like extra-skeletal osteosarcoma, Ewing's sarcoma and epithelioid sarcoma. This entity is a late complication to trauma and prolonged high pressure state within the leg compartments. With imaging alone, the differential of soft tissue sarcoma could be ruled out but typical natural history of disease and radiopathological features aided in the diagnosis.

Background: Soft tissue specifications and facial values ​​vary depending on the underlying skeletal structures. To achieve the ideal treatment result and patient satisfaction, one must know the attractive soft tissue specifications compatible with each type of malocclusion. This study aims to analyze the facial measurements that contribute to perceived facial attractiveness in patients with vertical growth patterns and skeletal class I malocclusion, focusing on gender-specific differences.

Medial capsulorrhaphy is an important step in hallux valgus correction surgery; however, studies on this technique are limited. This study aimed to evaluate the viability and efficacy of modified medial capsulorrhaphy using figure-of-eight sutures for hallux valgus compared to the conventional technique. Retrospective analysis was performed on patients with hallux valgus, comparing a group receiving standard longitudinal capsulorrhaphy (Group 1) and a group that underwent modified capsulorrhaphy using figure-of-eight sutures (Group 2).

We report a case of a 45-year-old gentleman who presented to our major trauma centre after sustaining a penetrating high-pressure paint injection injury to the neck. This rare mechanism of injury is most commonly reported to affect the non-dominant hand, occurring due to the malfunction or misuse of industrial paint machines, causing a piercing soft tissue injury with high-pressure fluid. The unique challenges faced in managing penetrating injuries to the neck are due to the density of vital visceral structures in the region, including major blood vessels and the upper aerodigestive tract.

Background Fracture of nickel-titanium (Ni-Ti) instruments in root canals is commonly associated with compromised outcomes in endodontic treatment. There is no single, universally accepted approach for managing this complication. The objective of this study is to evaluate the effectiveness of an Nd: YAP laser-assisted protocol in removing fractured Ni-Ti files in teeth with minimal root curvature (less than 15 degrees).
