If time has passed since injury, it can also lead to wrist arthritis. 28 (6): 1771-84. - it differs from Colles' or Smith's Fracture in that the dislocation is the most striking radiographic finding; - volar Barton's is more common than dorsal Barton frxs; - mechanism: - usually result from a fall upon an outstretched arm, leading to dorsiflexion stress and tension failure of volar lip of radius; What is the next most appropriate step in management? Diagnosis is generally made with radiographs of the wrist but may require CT for confirmation. The combination of a capitate fracture and a scaphoid waist fractureis known as "scaphocapitate syndrome" . Rathachai Kaewlai, Laura L. Avery, Ashwin V. Asrani, Hani H.

In the early stages of this disease, the x-rays may be normal and other tests are needed to confirm the diagnosis. Treatment is nonoperative for non-displaced fractures but displaced or intra-articular fractures require ORIF.

At the time the article was created Andrew Murphy had no recorded disclosures. The rest of the carpal bones are in a normal anatomic position in relation to the radius. They often are not diagnosed initially and present delayed as lunate osteonecrosis, which is also known as Kienbock disease. Distal Radius Fracture Non-Spanning External Fixator . The lunate is made up of the volar pole, body, and dorsal pole. Classification. Diagnosis is made clinically and radiographically with orthogonal radiographs of the wrist, Treatment can be nonoperative or operative depending on fracture stability and fracture displacement as well as patient age and activity demands, accounts for 17.5% of all fractures in adults, younger patients due to high energy mechanisms, older patients due to low energy mechanisms (i.e. educational laws affecting teachers. . A 45-year-old construction worker sustains a fall and presents with an isolated injury to his upper extremity. DISI (dorsal intercalated segmental instability), scapholunate dissociation causes the scaphoid to flex palmar and the lunate to dorsiflex, if left untreated the DISI deformity can progress into a, DISI deformity may also develop secondary to distal pole of the scaphoid excision for treatment of STT arthritis, DISI is a form of carpal instability dissociative, c-shaped structure connecting the dorsal, proximal and volar surfaces of the scaphoid and lunate bones, dorsal fiber thickened (2-3mm) compared to volar fibers, dorsal component provides the greatest constraint to translation between the scaphoid and lunate bones, proximal fibers have minimal mechanical strength, Overview of wrist ligaments and biomechanics, acute FOOSH injury vs. degenerative rupture, age, nature of injury, duration since injury, degree of underlying arthritis, level of activity, pain increased with loading across the wrist (e.g. Late treatment of a dorsal transscaphoid, transtriquetral perilunate wrist dislocation with avascular changes of the lunate.

A 35-year-old professional football player complains of severe wrist pain after making a tackle. At the time of the index operation, there was no distal radioulnar joint instability after plating of the radius. He initially thought it was a sprain, but presents due to continued pain worsened by push-ups. He denies any new trauma, and has followed all post-operative activity restrictions. There is injury of all of the perilunate ligaments, most significantly the dorsal radiolunate ligament. A four-stage process to describe perilunar instability has been described,where lunate dislocation represents stage IV 2. disruption of the normally smooth line made by tracing the proximal articular surfaces of the hamate and capitate, lunate overlaps the capitate and has a 'triangular' or 'piece of pie' appearance (also seen in perilunate dislocation), signet ring sign: rounded appearance of the scaphoid tubercle due to rotatory subluxation from injury to the scapholunate ligament, lunate seen displaced and angulated volarly, lunate does not articulate with capitate or radius (as opposed to perilunate dislocation where the lunate remains aligned with the radius). A 32-year-old ballet dancer sustains a distal radius fracture, and is subsequently closed reduced and casted. Perilunate dislocations and fracture-dislocations are relatively uncommon injury patterns in acute wrist trauma. She underwent open reduction and fixation of the distal radius fracture, and current radiographs are shown in Figure B.

(OBQ06.102) Like the scaphoid bone, the lunate also has a tenuous retrograde blood supply off of an interosseus arterial branch, and it has the same inherent risk of poor healing and AVN . The black dot in the photo is the capitate. Treatment is designed to relieve pain and restore function.Your hand surgeon will advise you of the best treatment options and explain the risks, benefits and side-effects of various treatments for Kienbocks disease.
