The ulnar corner is complex with many anatomical structures and many potential pathologies. This may render diagnosis and treatment a challenge. Meticulous history taking and examination are required, supplemented, if necessary, by tests such as X-ray, MRI, and arthroscopy. Condition include ECU and FCU tendinopathy; hook of hamate fracture; carpal instability; osteoarthritis of the DRUJ, pisotriquetral joint and lunatehamate joint; degenerative and traumatic lesions of the TFCC; ulnar neuropathy, and hypothenar hammer syndrome. Successful treatment depends on accurate diagnosis; non-operative measures usually suffice but surgical options include excision arthroplasty (e.g. pisiform arthritis), joint replacement (e.g. ulnar head), neurolysis (e.g. ulnar nerve neuropathy), surgical debridement (e.g. TFCC central perforations and lunate–hamate arthritis), and ulnar shortening (ulnocarpal impaction).

Mucocele of the paranasal sinuses are benign cystic lesions filled with mucus. They occur in the sphenoid sinus in 1–2% of all paranasal sinuses, most often in the fourth decade of life. Clinical manifestations are non-specific, caused by pressure expansion into anatomical structures immediately adjacent to the sphenoid sinus. They are manifested by headaches, dropped eyelids, impaired movement of the globe, and impaired vision. In the differential dia­gnosis, it is necessary to distinguish them from tumour processes and processes propagating from the intracranium. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) play an important role in the dia­gnosis, the definitive dia­gnosis is determined by perioperative findings and histological examination. Curative surgical options include endoscopic transnasal sphenoidotomy with marsupialization. In this article, we present a case of a patient with a mucocele of the sphenoid sinus, which was the cause of unilateral blindness. Keywords: marsupialization – mucocele – sphenoid sinus – endoscopic transnasal sphenoidotomy

18 consecutive patients suspected of and treated for an acute scaphoid fracture were examined by lowfield MRI. This showed 11 fractures while seven scaphoids were considered normal. T1 weighted images showed a fracture as an area of decreased signal intensity. Two radiologically obvious fractures produced normal MR images. These fractures proved to be the result of old trauma. A wide spectrum of additional traumatic lesions in the wrists, not detected by routine X-ray analysis, were also demonstrated. These included seven fragmented triangular fibrocartilages (TFC), torn scapho-lunate ligaments in four cases and one torn triquetro-lunate ligament. Bone bruises of other carpal bones and seven other carpal fractures were also detected. Low field MRI can be used to show scaphoid fractures and allows diagnosis of additional or simulating lesions.

The review presents the analysis of domestic and foreign literature, selecting the available scientific data on the features of constitutional and X-ray anatomy of the chest in adolescents and adults. The size and shape of the chest depends on age, sex and anthropometric parameters: height, body mass index, and also the presence of concomitant pathology. These patterns are characteristic of individual anatomical structures of the chest: sternum, ribs, spine and diaphragm. The study of constitutional anatomy is necessary for the development of morphological foundations for the interpretation of the results of intravital imaging of the chest and organs, justification of various methods of surgical access to the organ and structures of the chest and chest cavity.
