Overall, carpal dislocations comprise less than 10% of all wrist injuries. What additional data is most necessary to obtain before a reduction is attempted? Patients often prefer to hold their fingers in partial flexion due to pain on extension. Data Trace Publishing Company (OBQ08.179) (OBQ18.216) Lunate fractures account for around 4% of all carpal fractures 1.

Lunate dislocation. Classification. A 35-year-old professional football player complains of severe wrist pain after making a tackle. Volar pole fractures are more commonly observed as the lunate is compressed by the capitate. In lunate dislocations, disruption of Gilula's arcs can be appreciated with disruption of spaces between the proximal and distal carpal bones. Chronic DISI deformities may be indicated for fusion procedures depending on degree of arthritis and patient symptoms.

Towson, MD 21204 Two-point discrimination is now >10mm in these fingers. Treatment requires urgent closed versus open reduction and stabilization. What is the next most appropriate step in management? As he tried to brace his fall, he landed directly on his extended and ulnarly deviated left hand. It is the second most common carpal bone injury in children 1. He denies any new trauma, and has followed all post-operative activity restrictions. (OBQ04.233) Perilunate instability represents about 7 percent of all injuries to the carpus [ 5 ]. Pearls/pitfalls. 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. There is injury of all of the perilunate ligaments, most significantly the dorsal radiolunate ligament.

Capitate fractures are classified by the anatomic location of the fracture, along with what other concomitant injuries may be present. A lumberjack in rural Michigan falls 10 feet from an Evergreen branch onto an outstretched arm and develops immediate wrist pain. What is the most appropriate treatment at this time? Phalanx Fractures are common hand injuries that involve the proximal, middle or distal phalanx. Given the lunate's position in the wrist, there is significant overlap from other carpal bones and hence these fractures can be subtle. These should not be confused with perilunate dislocations in which the radiolunate articulation is preserved and the rest of the carpus is displaced dorsally.

Lunate fracturesare a carpal injury that if left untreated, can result in significant carpal instability. Capitate fractures account for 1-2% of all carpal fractures 1,2. Isolated fractures without displacement or subluxation can be managed conservatively, however fractures that possess joint subluxation are unstable and require surgical intervention 2. These should not be confused with perilunate dislocations in which the radiolunate articulation is . - Discussion: (OBQ12.168) Toe fractures of this type are rare unless there is an open injury or a high-force crushing or shearing injury. Phalanx fractures of the hand are some of the most common fractures occurring in humans.

Terry Thomas sign: This is seen on an AP wrist film and is indicated by a gap >3mm between the scaphoid and lunate bones Cortical Ring sign: occurs when the scaphoid is in a flexed position, making the scaphoid tubercle more prominent.A measure distance less than 7mm between the end of the cortical ring and the proximal end of the scaphoid suggests scapholunate dissociation and instability.

The black dot in the photo is the capitate. Incompetence of which of the following anatomic structures is the most likely etiology of this finding? When the lunate is severely fracture, collapsed, or arthritic, salvage treatments such as lunate and other wrist bone removal may be necessary. It can be caused by multiple factors such as: Damage to the lunate can lead to pain and stiffness. At the time of the index operation, there was no distal radioulnar joint instability after plating of the radius. (SAE07SM.38) Diagnosis is confirmed with either a radiographic carpal tunnel view or CT scan. Lunate Dislocation (Perilunate dissociation). Stage IV denotes a true lunate dislocation, involving a . push up position), may be associated with wrist instability or weakness, may see swelling over the dorsal aspect of the wrist, tenderness in the anatomical snuffbox or over the, pain increased with extreme wrist extension and radial deviation, when deviating from ulnar to radial, pressure over volar aspect of scaphoid subluxates the scaphoid dorsally out of the scaphoid fossa of the distal radius, and a clunk is palpated when pressure is released as the scaphoid reduces back over the dorsal rim of the radius, a painful clunk during this maneuver may indicate insufficiency of scapholunate ligament, clenched fist (can exaggerate the diastasis), dorsal tilt of lunate leads to SL angle > 70, may be used as screening tool for arthroscopy, always assess the contralateral wrist for comparison, may demonstrate the presence of a tear but cannot determine the size of the tear, positive finding of a tear may indicate the need for wrist arthroscopy, often overused as a screening modality for SLIL tears, requires careful inspection of the SLIL by a dedicated radiologist to confirm diagnosis, Carpal instability nondissociative (CIND), splinting and close follow-up with repeat imaging and clinical response with acute injuries, most people feel casting alone is insufficient, acute scapholunate ligament injury without carpal malalignment, ligament pathoanatomy is ammenable to repair, if pathoanatomy of SL ligament injury is a scaphoid fx than repair with, small incision is made just distal to the radial styloid, care to avoid cutting the radial sensory nerve branches, often added to a ligament repair and remains a viable alternative for a chronic instability when ligament repair is not feasible, place two k-wires in parallel into the scaphoid bone, reduce the SL joint by levering the scaphoid into extension, supination and ulnar deviation and lunate into flexion and radial deviation, confirm reduction of the SL joint under fluoroscopy, FCR tendon transfer (direct SL joint reduction), ECRB tendonosis (indirect SL joint reduction), weave not recommended due to high incidence of late failure.

AP and lateral radiographs of the wrist are shown in figures A and B respectively. Lunate dislocations typically occur due to a fall on an outstretched hand (or during a motor vehicle injury) where there is forceful dorsiflexion of the wrist 3.

The lunate is one of the eight small bones in the wrist. FOOSH), high incidence of distal radius fractures in women > 50 years old, DEXA scan is recommended for women with distal radius fractures, fall on outstretched hand (FOOSH) is most common in older population, higher energy mechanism more common in younger patients, includes the radial styloid and scaphoid fossa, attachment sites for the brachioradialis tendon, long radiolunate ligament, and radioscaphocapitate ligament, serves as a buttress to resist radial carpal translation, functions as a load-bearing platform for activities performed with the wrist in ulnar deviation, holds the carpus out to length radially, allowing a more uniform distribution of load across the scaphoid and lunate facets, serves as an anchor for the radioscaphocapitate ligament that prevents ulnar translation of the carpus, transmits load from the carpus to the forearm, based on joint involvement (radiocarpal and/or radioulnar) +/- ulnar styloid fracture, divides intra-articular fractures into
