(OBQ17.87) Around 60% of perilunate dislocations are associated with a scaphoid fracture which is then termed a trans-scaphoid perilunate dislocation . Lunate fractures account for around 4% of all carpal fractures 1. Lunate dislocations are far less common than the less severe perilunate dislocation. Diagnosis can be confirmed with orthogonal radiographs of the involve digit. The lunate bone articulates with the scaphoid, the distal radius, and the TFCC. 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. Technique guides are not considered high yield topics for orthopaedic standardized exams including ABOS, EBOT and RC.

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. Hamate Body Fractures are rare carpal fractures that can be associated with 4th or 5th metacarpal fractures. The lunate is made up of the volar pole, body, and dorsal pole. Scapholunate Ligament Injury is a source of dorsoradial wrist pain with chronic injuries leading to a form of wrist instability (DISI deformity). Flashcards. Diagnosis of DISI deformity can be made with lateral wrist radiographs showing a scapholunate angle. (SBQ07SM.38) It works closely with the two forearm bones (the radius and ulna) to help the wrist move. The lunate is a central bone in the wrist that is important for proper movement and support of the joint (Figure 1). Inability to flex the thumb interphalangeal joint. Scapholunate Advanced Collapse Article - StatPearls Wrist osteoarthritis - Wikipedia (OBQ12.244) Ulnar gutter splint/cast. - 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; Management should consist of.

The plate may need to removed once the fracture is healed to reduce the chance of flexor pollicis longus injury, The plate may need to removed once the fracture is healed to reduce the chance of flexor carpi radialis injury, The plate may need to removed once the fracture is healed to reduce the chance of flexor digitorum superficialis index finger injury, The patient should undergo revision fixation as soon as possible, The plate is in appropriate position and will likely never need to be removed. A 52-year-old farmers periodic wrist pain has been managed with non-operative modalities to include two injections in the last 8 months. Lunate Fracture - an overview | ScienceDirect Topics Multidetector CT of Carpal Injuries: Anatomy, Fractures, and Fracture-Dislocations1. Radiographs are provided in Figures A-C. The lunate is one of the eight small bones in the wrist. Most displaced fractures of the lesser toes can be managed by family physicians if there are no indications for referral. Kienbocks disease is also known as avascular necrosis (AVN) of the lunate. When the lunate is severely fracture, collapsed, or arthritic, salvage treatments such as lunate and other wrist bone removal may be necessary. lunate fracture orthobullets - paperravenbook.com Lunate fractures are relatively uncommon, representing about 4 percent of all carpal bone injuries [ 1-4 ]. The instrument touches a structure that prevents ulnar translocation of the carpus after a PRC. A 58-year-old man underwent distal radius ORIF with a volar locking plate yesterday. Changes for Fat Loss by with a free trial. (OBQ04.233) Check for errors and try again. The lunocapitate articulation may be disrupted resulting in a dorsal perilunate dislocation, or in the case of concomitant scaphoid fracture, the wrist may undergo a transscaphoperilunate dislocation. (OBQ07.226) - most frequently dislocated carpal bone; Phalanx Fractures - Hand - Orthobullets scaphoid is flexed and lunate is extended as scapholunate ligament no longer restrains this articulation, lunate extended > 10 degrees past neutral, resultant scaphoid flexion and lunate extension creates, abnormal distribution of forces across midcarpal and radiocarpal joints, malalignment of concentric joint surfaces, describes predictable progression of degenerative changes from the radial styloid to the entire scaphoid facet and finally to the unstable capitolunate joint, as the capitate subluxates dorsally on the lunate, key finding is that the radiolunate joint is spared, unlike other forms of wrist arthritis, since there remains a concentric articulation between the lunate and the spheroid lunate fossa of the distal radius, Arthritis between scaphoid and radial styloid, Arthritis between scaphoid and entire scaphoid facet of the radius, While original Watson classification describes preservation of radiolunate joint in all stages of SLAC wrist, subsequent description by other surgeons of "stage IV" pancarpal arthritis observed in rare cases where radiolunate joint is affected, validity of "stage IV" changes in SLAC wrist remains controversial and presence pancarpal arthritis should alert the clinician of a different etiology of wrist arthritis, patients localize pain in region of scapholunate interval, tenderness directly over scapholunate ligament dorsally, will not be positive in more advanced cases as arthritic changes stabilize the scaphoid, with firm pressure over the palmar tuberosity of the scaphoid, wrist is moved from ulnar to radial deviation, positive test seen in patients with scapholunate ligament injury or patients with ligamentous laxity, where the scaphoid is no longer constrained proximally and subluxates out of the scaphoid fossa resulting in pain, when pressure removed from the scaphoid, the scaphoid relocates back into the scaphoid fossa, and typical snapping or clicking occurs, obtain standard PA and lateral radiographs, PA radiograph will reveal greater than 3mm diastasis between the scaphoid and lunate, PA radiograph shows sclerosis and joint space narrowing between scaphoid and the entire scaphoid fossa of distal radius, PA radiograph shows sclerosis and joint space narrowing between the lunate and capitate, and the capitate will eventually migrate proximally into the space created by the scapholunate dissociation, thinning of articular surfaces of the proximal scaphoid, scaphoid facet of distal radius and capitatolunate joint with synovitis in radiocarpal and midcarpal joints, NSAIDs, wrist splinting, and possible corticosteroid injections, prevents impingement between proximal scaphoid and radial styloid, may be performed open or arthroscopically via 1,2 portal for instrumentation, since posterior and anterior interosseous nerve only provide proprioception and sensation to wrist capsule at their most distal branches, they can be safely dennervated to provide pain relief, can be used in combination with below procedures for Stage II or III, contraindicated with caputolunate arthritis (Stage III SLAC) because capitate articulates with lunate fossa of the distal radius, contraindicated if there is an incompetent radioscaphocapitate ligament, excising entire proximal row of carpal bones (scaphoid, lunate and triquetrum) while preserving, provides relative preservation of strength and motion, also provides relative preservation of strength and motion, wrist motion occurs through the preserved articulation between lunate and distal radius (lunate fossa), similar long term clinical results between scaphoid excision/ four corner fusion and proximal row carpectomy, wrist fusion gives best pain relief and good grip strength at the cost of wrist motion, - Scaphoid Lunate Advanced Collapse (SLAC), Lunate Dislocation (Perilunate dissociation), Gymnast's Wrist (Distal Radial Physeal Stress Syndrome), Scaphoid Nonunion Advanced Collapse (SNAC), Carpal Instability Nondissociative (CIND), Constrictive Ring Syndrome (Streeter's Dysplasia), Thromboangiitis Obliterans (Buerger's disease).

Diagnosis is confirmed with either a radiographic carpal tunnel view or CT scan. Diagnosis is made clinically with progressive wrist pain and wrist instability with radiographs showing advanced arthritis of the radiocarpal and midcarpal joints (radiolunate joint spared). (OBQ18.216) There is no single cause of Kienbocks disease. Phalanx fractures of the hand are some of the most common fractures occurring in humans. Most likely, the most reliable test to assess the blood supply of the lunate is Magnetic Resonance Imaging (MRI). Stage IV denotes a true lunate dislocation, involving a . As he tried to brace his fall, he landed directly on his extended and ulnarly deviated left hand. Urgent reduction and surgical repair of disrupted ligaments is required to prevent long-term joint dysfunction. (OBQ18.177) (OBQ12.105) - Discussion: Treatment of acute SL ligament injuries may be immobilization versus operative repair/reconstruction depending on degree of displacement. toe phalanx fracture orthobullets Lunate dislocations are an uncommon traumatic wrist injury that require prompt management and surgical repair.

Wrist Dislocation by Kadeer M Halimi from emedicine.com. Late treatment of a dorsal transscaphoid, transtriquetral perilunate wrist dislocation with avascular changes of the lunate. Preoperatively, he reported some mild sensory disturbances in the volar thumb and index finger, but had 2-point discrimination of 6mm in each finger. 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. This is an AAOS Self Assessment Exam (SAE) question. (OBQ05.25) immobilization in a long arm thumb spica cast. On examination, her wrist is mildly swollen and she is unable to actively oppose her thumb. Capitate fractures are classified by the anatomic location of the fracture, along with what other concomitant injuries may be present. His radiograph is shown in Figure A.
