Ulnar-sided wrist pain. Part I: anatomy and physical examination

Ulnar-sided wrist pain is a common complaint, and it presents a diagnostic challenge for hand surgeons and radiologists. The complex anatomy of this region, combined with the small size of structures and subtle imaging findings, compound this problem. A thorough understanding of ulnar-sided wrist anatomy and a systematic clinical examination of this region are essential in arriving at an accurate diagnosis. In part I of this review, ulnar-sided wrist anatomy and clinical examination are discussed for a more comprehensive understanding of ulnar-sided wrist pain

Ulnar-sided wrist pain. II. Clinical imaging and treatment

Pain at the ulnar aspect of the wrist is a diagnostic challenge for hand surgeons and radiologists due to the small and complex anatomical structures involved. In this article, imaging modalities including radiography, arthrography, ultrasound (US), computed tomography (CT), CT arthrography, magnetic resonance (MR) imaging, and MR arthrography are compared with regard to differential diagnosis. Clinical imaging findings are reviewed for a more comprehensive understanding of this disorder. Treatments for the common diseases that cause the ulnar-sided wrist pain including extensor carpi ulnaris (ECU) tendonitis, flexor carpi ulnaris (FCU) tendonitis, pisotriquetral arthritis, triangular fibrocartilage complex (TFCC) lesions, ulnar impaction, lunotriquetral (LT) instability, and distal radioulnar joint (DRUJ) instability are reviewed

Avaliação artroscópica e macroscópica da faceta medial do semilunar Arthroscopic and macroscopic evaluation of the lunate medial facet

OBJETIVO: avaliar a correlação entre a presença de uma faceta medial do semilunar e a incidência de lesões ligamentares e artrose do pólo proximal do hamato. MÉTODOS: Avaliação artroscópica e dissecação dos punhos foram efetuados em cadáveres. RESULTADOS: Houve uma correlação clara, estatisticamente significativa entre artrose do pólo proximal do hamato e a presença da faceta medial do semilunar. CONCLUSÃO: Artrose do pólo proximal do hamato está correlacionada com a presença do tipo II semilunar. Nível de Evidência III, Estudo de pacientes nãoconsecutivos; sem padrão de referência "ouro" aplicado uniformemente<br>OBJECTIVE: To evaluate the correlation between the presence of a lunate medial facet and the incidence of ligament lesions of the wrist and arthrosis of the proximal pole of the hamate. This study was carried out on cadavers. METHODS: Arthroscopic evaluation and dissection were performed on cadaver wrists. RESULTS: There was a clear, statistically significant correlation between arthrosis of the proximal pole of the hamate and the presence of a medial facet on the lunate. CONCLUSION: Arthrosis of the proximal pole of the hamate is correlated with the presence of a type II lunate. Level of Evidence III, Study of nonconsecutive patients; without consistently applied reference ''gold'' standard
