Restorative Tissue Transplantation Options for Osteochondral Lesions of the Talus: A Review.

Symptomatic osteochondral lesions of the talus remain a challenging problem due to inability for cartilage lesions to heal. Numerous treatment options exist, including nonoperative management, marrow stimulating techniques, and autograft-allograft. Arthroscopic marrow stimulation forms fibrocartilage that has been shown to be biomechanically weaker than hyaline cartilage. Restorative tissue transplantation options are being used more for larger and cystic lesions. Newer biologics and particulated juvenile cartilage are currently under investigation for possible clinical efficacy. This article provides an evidenced-based summary of available literature on the use of biologics for treatment of osteochondral lesions of the talus.

Osteochondroma of the phalanx: a late Roman case.

Accounting for 20-50% of all benign forms, solitary osteochondromae are the most common kind of bone tumour. The long bones of the lower extremity are the most frequently affected; the small bones of the hands and feet, the pelvis, the scapula, and the spine are less usual locations. This paper describes an osteochondroma in a proximal phalanx of the hand of a female aged between 17 and 25 years buried in a Late Roman necropolis from SE Spain. The bone displayed a solitary osteochondroma, which was confirmed by macroscopic and radiographic examination. This is the first palaeopathological example of a solitary sessile osteochondroma of the hand.

Enfermedad de Jacob asociada con el síndrome de disfunción de la articulación temporomandibular: Presentación de un caso / Jacob’s disease associated with temporomandibular joint dysfunction: A case report

La enfermedad de Jacob se describe como una entidad infrecuente en la cual se establece una formación articular sinovial entre una apófisis coronoide mandibular elongada y el hueso malar homolateral. El Síndrome de disfunción de la articulación temporomandibular(ATM) ha sido postulado como posible factor etiológico del alargamiento este proceso coronoideo. Presentamos el caso de una mujer de 23 años con un desplazamiento discal de ATM de larga evolución y limitación de la apertura oral, que desarrolló una asimetría malar progresiva. La paciente fue sometida a tratamiento quirúrgico mediante una coronoidectomía intraoral y una artroscopia de la ATM homolateral en el mismo acto operatorio. El diagnóstico histológico de la apófisis coronoide examinada fue de exóstosis óseo-cartilaginosa con presencia de fibrocartílago articular en dicha formación. A pesar de la baja prevalencia de esta patología, debe ser considerada como un posible diagnóstico en aquellos pacientes con limitación progresiva de la apertura oral de larga evolución, si bien en ocasiones puede acompañarse de una disfunción articular crónica concomitante como posible causa de la misma

Jacob´s disease is regarded a rare condition in which a joint formation is established between an enlarged mandibular coronoid process and the inner aspect of the zygomatic body. Chronic temporomandibular joint (TMJ) disk displacement has been proposed as etiological factor of coronoid process enlargement. We present a 23-year-old woman with long-standing TMJ dysfunction and restricted interincisal opening, who developed a progressive zygomatic assymetry. The patient underwent treatment by intraoral coronoidectomy and homolateral TMJ arthroscopy in the same surgery. The histopathological diagnosis of the coronoid sample was cartilage-capped exostoses with presence of articular fibrous cartilage. Although the low prevalenceof this entity, it should be considered as a possible diagnosis inpatients with progressive limitation of mouth opening, althougha TMJ syndrome may be present as a cause of this entity
