MSK MRI

FSPD image demonstrates full-thickness tear of the membranous portion (not shown) and volar band of the scapholunate ligament (SLL), and partial tear of dorsal band. Note the hyperintense signal and thickening of the radioscaphocapitate (RSC) ligament and long radiolunate ligament (LRL), consistent with grade I injury or sprain. LRL should not be mistaken for intact volar SLL. #WristMRI, #WristA..

The lunate attachment is just dorsal to the long radiolunate ligament (LRL), (=radiolunotriquetral ligament (RLT)) attachment and immediately proximal to the cartilage surface. #WristMRI, #WristAnatomy, #WristLigament, #WristInstability, #Wrist MRI, #Wrist anatomy, #wrist ligament, #안산에이스병원, #Radioscaphocapitate ligament, #Long radiolunate ligament, #Scapholunate Ligament

An interligamentous sulcus (yellow dots), demonstrating fluid signal can sometimes be identified between the radioscaphocapitate (RSC) ligament and long radiolunate ligament (LRL), and should not be mistaken for a tear. #WristMRI, #WristAnatomy, #WristLigament, #WristInstability, #Wrist MRI, #Wrist anatomy, #wrist ligament, #안산에이스병원, #Radioscaphocapitate ligament, #Long radiolunate ligament, #In..

At the level of the scaphoid (left), the radioscaphocapitate (RSC) ligament is seen palmar to the waist of the scaphoid, being distal to the long radiolunate ligament (LRL). At the level of the lunate (right), MRI shows a short radiolunate ligament (SRL) passing from the volar lip of the distal radius at the lunate facet, to the volar lunate cortex. Immediately distal to the SRL is the LRL, foll..

Ganglion cysts are also commonly associated with extrinsic ligaments. The volar ganglion cyst with a loculated component interdigitating with the fibers of the long radiolunate (LRL) or radiolunotriquetral ligament (RLT). #WristMRI, #WristAnatomy, #WristLigament, #WristInstability, #Wrist MRI, #Wrist anatomy, #wrist ligament, #안산에이스병원, #Radioscaphocapitate ligament, #Long radiolunate ligament, #..

The radial and palmar origins of the radioscaphocapitate ligament (RSC) and the radiolunotriquetral ligament (RLT) on the radial styloid process are intimately associated. Like most capsular ligaments, they are predominantly low signal with linear higher-signal striations. #WristMRI, #WristAnatomy, #WristLigament, #WristInstability, #Wrist MRI, #Wrist anatomy, #wrist ligament, #안산에이스병원, #Radiosc..

The radial collateral ligament is readily visible in this patient, with a small wrist joint effusion, extending from the tip of the radial styloid process to the scaphoid tuberosity. #WristMRI, #WristAnatomy, #WristLigament, #WristInstability, #Wrist MRI, #Wrist anatomy, #wrist ligament, #안산에이스병원, #Radial collateral ligament,

The palmar extrinsic ligaments are more important in wrist stabilization as they are thicker and stronger than the dorsal extrinsic wrist ligaments. The palmar extrinsic ligaments are more important in wrist stabilization as they are thicker and stronger than the dorsal extrinsic wrist ligaments.

Here is a large superolateral humeral head erosion and synovial thickening and joint effusion. Is this a Hill-Sachs Lesion? Hill-Sachs lesions are strongly associated with anteroinferior glenoid fracture, anteroinferior glenoid labrum tear (Bankart lesion), and joint capsular injury. However, there are several common non-traumatic bones and joint diseases that rarely mimic Hill-Sachs lesions. An..
