FRACTURES OF THE CLAVICLE Le Kim Trong MD., Le Nghi Thanh Nhan MD. Hogar; Descubre. The trapezoid is the more lateral of the two ligaments and attaches to the distal clavicle approximately 2 cm from the AC joint.9 The conoid ligament, which is located more medially, attaches to the clavicle approximately 4 cm from the AC joint. Orthobullets dorsal extrinsic dorsal intercarpal ligaments dic the dorsal intercarpal ligament originates from the dorsum of the triquetrum and inserts on the dorsal aspects of the trapezoid and the waist of the scaphoid. Although traditionally the mandible and base of skull are thought to form a complete bony ring, interrupted only by the TMJs.This should mean that the mandible should fracture in two places (akin to the bony pelvis) making single fractures uncommon, but this in fact not the case, with ~40% of fractures … Despite these additional views 30% of scaphoid fractures remain occult on any image taken at the time of injury. Metacarpal fracture and carpal fractures occur slightly more rarely, at a rate of approximately 0.1% of children overall (Chung 2001). GROUP II – Distal third fractures (15%) Type I – Minimally displaced / interligamentous; Type II – Displaced fractures, fracture medial to the coracoclavicular ligaments IIA – Both ligaments (conoid and trapezoid) attached to the distal fragment; IIB – Conoid torn, trapezoid attached to the distal fragment Distal radius fracture is likely the most frequent cause of traumatic ACTS secondary to compression of the median nerve caused by hemorrhage or edema. ORTHO BULLETS Orthopaedic Surgeons & Providers Annotated image. From the case rID: 45880) Diagnostic Imaging. ORTHO BULLETS Orthopaedic Surgeons & Providers Coccygeal fractures are generally low-severity injuries, which nonetheless can be diagnostically challenging. Midshaft Clavicle fractures. The protected position of the trapezoid between the base of the second metacarpal, capitate, trapezium, and scaphoid and the strong ligamentous attachments provide much stability, limiting the likelihood of an isolated fracture. In addition, if osteoporosis or other disease has weakened the bones, just doing everyday activities may result in a stress fracture. Epidemiology These fractures have an incidence 0.4% to 2.7%, and males are affected more-so than females. The management of these cases has varied from complete excision to open or closed reduction, with or without percutaneous wiring. Extension fractures of the distal end of the radius (reverse Colles fracture/Smith fracture) A true Smith fracture is a fracture of the entire thickness of the distal radius, 0.5-1 in (1.3-2.5 cm) above the wrist. For this type of fracture, your doctor may place your forearm and hand in a cast or a splint. In light of this, ORIF is indicated. I : Fracture line runs between the intact conoid and trapezoid ligaments, resulting in minimal fracture displacement; II: Fracture line medial to coracoclavicular ligaments resulting in greater fracture displacement and higher incidence of nonunion. Clavicle fractures are common and the diagnosis is often apparent based on history and physical exam alone; The majority of clavicle fractures can be managed non-operatively but operative indications depend on the fractureâ s location, stability, and amount of displacement for midshaft fractures A fall onto the lateral shoulder most … Carpal bone dislocation is uncommon. Type IIA and IIB and Type V fractures (highlighted in red boxes below) Type IV is non operative because it is a physeal fracture in pediatrics. obesity, overlying bowel gas/faeces).. INTRODUCTION.

MB BULLETS Step 2 & 3 For 3rd and 4th Year Med Students. … … Displaced fracture medial to the conoid and trapezoid ligaments or separation of clavicle from the the ligaments. Isolated fractures of the trapezium are only thought to account for 3-5% of all carpal fractures 1,2.. Given that management of coccygeal fractures is nearly always non-operative, some radiology literature suggests that x-ray … Retrograde IMN is not a … No fracture. IIA : Conoid and trapezoid attached to distal fragmetnt 12 This classification was developed before widespread use of MRI, and we are unaware of any study that has confirmed the integrity of the trapezoid and conoid ligaments in type IIA and IIB injuries. The … The stability of comminuted fractures of the distal part of the radius with volar fragmentation is determined not only by the reduction of the major fragments but also by the reduction of the small volar lunate fragment. The distal volar lunate fragment is the site of origin of the strong volar radiolunate ligaments which insert onto the lunate, and so displacement of this small piece … Trapezoid fractures occur when the second metacarpal butts up against it. The circle indicated the dislocated trapezoid bone in the distal carpal row. Each scaphoid fracture is different, however, and as a result of these differences, the treatment of each fracture and/or nonunion may vary.

The highest incidence of phalangeal fractures occurs in the 0-4 year age group, at a rate of approximately 0.2% of children in that age group. Pathology. They can be broadly classified into ridge (most common 2) and body fractures.. Fractures to bones of the distal carpal row—comprising the trapezium, trapezoid, capitate, and hamate— are less frequent than fractures of bones in the proximal row … The Judet and Letournel classification is the most widely used classification system for acetabular fractures.It classifies acetabular fractures into ten major fracture patterns, which consist of five simple patterns and five complex patterns 1,2. Fracture near the thumb. Hand fractures are among the top five most common fractures occurring in childhood. A fracture of the carpal bones of the wrist may present with swelling and bruising. This part of the scaphoid bone has a good blood supply, which is necessary for healing. How is a scaphoid fracture diagnosed? Type 1: Middle 1/3 fractures.

The long-term consequences of not treating a scaphoid fracture can be significant. There are sixteen cases to date reported in the literature. Tibial tuberosity avulsion fractures are uncommon. Diagnosis may be delayed or missed due to coccygeal anatomy and patient/technical factors (e.g. 4 Botte and Gelberman 19 reported a 1% incidence of trapezoid fractures in comparison with all carpal bones. Scaphoid fractures that are closer to the thumb (distal pole) usually heal in a matter of weeks with proper protection and restricted activity. ORIF options include locked femoral plating or retrograde intramedullary nailing (IMN). Plain radiograph – recommended views. The decision for revision of the femoral component is guided by component stability versus loosening, with ORIF and revision arthroplasty indicated, respectively. This paper presents a case of an isolated dislocation of the trapezium without fracture, managed with closed reduction and … In Neer type IIB fractures, the conoid ligament is torn, but the trapezoid is presumed to remain attached to the distal fragment. From the case: Trapezoid dislocation. Neer … They often occur as a result of a high energy trauma and usually involve either direct or indirect axial loading 1.These are most commonly transverse loading … Conoid torn, trapezoid intact 30 Volar displacement of fracture fragments or direct contact with the median nerve can result in direct nerve contusion or ACTS.
