- immobilize forearm in neutral rotation w/ slight supination, w/ cast carefully molded over lateral side of ulna at level of fracture; - Type III - 20% Fractures in children. - realize that even w/ successful closed reduction of the ulna (and accompanying reduction of the radial head) that subsequently Vol 2: 520. - apex of angular deformity of ulna usually indicates direction of radial head dislocation; - Reduction: Towson, MD 21204 If one of the forearm bones is injured, injury should be looked for in the other bone and in associated joints of the forearm, elbow, and wrist. - this ordinarily requires 6-10 wks depending on the age of pt; 40 (3):e216-e221. Milan: Maspero; 1814. vol 5: Bado JL. J Bone Joint Surg Br. Monteggia fracture-dislocations remain a relatively uncommon injury. (OBQ09.264) Repair of Bado II Monteggia Fracture: Case Presentation and Surgical Technique. In a retrospective study on the functional and radiologic long-term outcome of ORIF in 11 skeletally mature patients with Bado type I Monteggia fractures, Guitton et al found that the mean arc of elbow flexion increased from 110 at early follow-up to 120 at late follow-up. [14]. Ulna - Physiopedia Epub 2012 Oct 10. - associated nerve injury: 1967; 50:71-86. The character of the ulnar fracture is useful in determining optimal treatment. The fracture of the radial head was treated with either complete or partial excision of the fragments in twelve patients (with replacement with a silicone prosthesis in two), open reduction and internal fixation in ten patients, and no intervention in four patients. Robert J Nowinski, DO Clinical Assistant Professor of Orthopaedic Surgery, Ohio State University College of Medicine and Public Health, Ohio University College of Osteopathic Medicine; Private Practice, Orthopedic and Neurological Consultants, Inc, Columbus, Ohio Monteggia fractures and their variants are often misdiagnosed, however, because of the numerous atypical presentations of this injury in children. Monteggia fracture - Wikipedia [5] The mean arc of forearm rotation increased from 145 to 149.

The other two unsatisfactory results were in a patient who had had a Bado type-I fracture and in one who had had a Bado type-IV fracture. - keep elbow flexed ( > 90 deg), to relax biceps, so that full supination can be avoided w/o losing reduction; - Non Operative Treatment: Datta T, Chatterjee N, Pal AK, Das SK. HTML view of the file Chapter 10.html Take great care to avoid injury to the underlying skin. Compartment Syndrome in Operatively Managed Pediatric Monteggia Fractures and Equivalents. This principle also applies to aGaleazzi fracture, which is a fracture of the distal radius with concomitant dislocation of the distal radioulnar joint (DRUJ). different treatment protocol for children, may be part of complex injury pattern including, Fracture of the proximal or middle third of the ulna with, Fracture of the ulnar metaphysis (distal to coronoid process) with, Fracture of the proximal or middle third of the, Jupiter Classification of Type II Monteggia Fracture-Dislocations, Fracture extending to distal half of ulna, may or may not be obvious dislocation at radiocapitellar joint, may be loss of ROM at elbow due to dislocation, radial deviation of hand with wrist extension, AP and Lateral of elbow, wrist, and forearm, helpful in fractures involving coronoid, olecranon, and radial head, must ensure stabilty and anatomic alignment of ulna fracture, acute fractures which are open or unstable (long oblique), most Monteggia fractures in adults are treated surgically, ORIF of ulna shaft fracture, open reduction of radial head, failure to reduce radial head with ORIF of ulnar shaft only, Monteggia "variants" with associated radial head fracture, lateral decubitus position with arm over padded support, midline posterior incision placed lateral to tip of olecranon, develop interval between flexor carpi ulnaris and anconeus along ulnar border proximally, and interval between FCU and ECU distally, with proper alignment of ulna radial head usually reduces and open reduction of radial head is rarely needed, failure to align ulna will lead to chronic dislocation of radial head, treatment based on involved components (radial head, coronoid, LCL), if no improvement obtain nerve conduction studies, usually caused by failure to obtain anatomic alignment of ulna, If diagnosis is delayed greater than 2-3 weeks complication rates increase significantly, Adult Knee Trauma Radiographic Evaluation, Proximal Humerus Fracture Nonunion and Malunion, Distal Radial Ulnar Joint (DRUJ) Injuries.

Hess, MD (Frontiers #16, 2016), Monteggia Fracture Dislocation - Everything You Need To Know - Dr. Nabil Ebraheim. The ulna and interosseous membrane also may provide stable platforms for dislocation of the proximal radius, leading to the Monteggia fracture. Adults and unstable injuries generally require ORIF of the ulna. different treatment protocol for children, may be part of complex injury pattern including, Fracture of the proximal or middle third of the ulna with, Fracture of the ulnar metaphysis (distal to coronoid process) with, Fracture of the proximal or middle third of the, Jupiter Classification of Type II Monteggia Fracture-Dislocations, Fracture extending to distal half of ulna, may or may not be obvious dislocation at radiocapitellar joint, may be loss of ROM at elbow due to dislocation, radial deviation of hand with wrist extension, AP and Lateral of elbow, wrist, and forearm, helpful in fractures involving coronoid, olecranon, and radial head, must ensure stabilty and anatomic alignment of ulna fracture, acute fractures which are open or unstable (long oblique), most Monteggia fractures in adults are treated surgically, ORIF of ulna shaft fracture, open reduction of radial head, failure to reduce radial head with ORIF of ulnar shaft only, Monteggia "variants" with associated radial head fracture, lateral decubitus position with arm over padded support, midline posterior incision placed lateral to tip of olecranon, develop interval between flexor carpi ulnaris and anconeus along ulnar border proximally, and interval between FCU and ECU distally, with proper alignment of ulna radial head usually reduces and open reduction of radial head is rarely needed, failure to align ulna will lead to chronic dislocation of radial head, treatment based on involved components (radial head, coronoid, LCL), if no improvement obtain nerve conduction studies, usually caused by failure to obtain anatomic alignment of ulna, If diagnosis is delayed greater than 2-3 weeks complication rates increase significantly, Proximal Humerus Fracture Nonunion and Malunion, Distal Radial Ulnar Joint (DRUJ) Injuries. A Monteggia fracture involves a fracture of the ulna with disruption of the proximal radio-ulnar joint (PRUJ) and radiocapitellar dislocation (Bado, 1967). - Mechanism: - proposed mechanisms include direct blow & hyperpronation injuries as well- as the hyperextension theory; (3/76), Level 1 Bae DS. In addition, there are substantial differences between Monteggia injuries in children and adults. Monteggia fractures in children and adults. [QxMD MEDLINE Link]. Treatment may be closed reduction and casting for length stable ulna fractures with a stable radiocapitellar joint. [QxMD MEDLINE Link]. The relatively good results associated with nonoperative treatment of pediatric Monteggia injuries reflect the prevalence of stable (incomplete) fractures in children. Adults and unstable injuries generally require ORIF of the ulna. Although most pediatric fracture patterns can be managed conservatively with closed reduction and long arm casting, most adult fractures require open reduction and internal fixation (ORIF). - treated by reduction and stabilization of ulna followed by reduction of radial head via supination & direct pressure; The Monteggia fracture is a fracture of the proximal third of the ulna with dislocation of the proximal head of the radius. Monteggia Fractures in Pediatric and Adult Populations, Clifford R. Wheeless, III, M.D. encoded search term (Monteggia Fracture) and Monteggia Fracture. Galezzi's fracture-fracture to the distal radius accompanied by ulnar head dislocation at distal radio-ulna joint. [8] : The Bado classification is based on the recognition that the apex of the fracture is in the same direction as the radial head dislocation. PDF Variants of Monteggia Type Injury: Case Reports J Hand Surg Am. Pathology of the annular ligament in paediatric Monteggia fractures. 35 (3):e434-7. J Bone Joint Surg Br. 36 Suppl 1:S67-70. [2 . Leonidou A, Pagkalos J, Lepetsos P, Antonis K, Flieger I, Tsiridis E, et al. He founded Orthopaedic Specialists of North Carolina in 2001 and practices at Franklin Regional Medical Center and Duke Raleigh Hospital. A review of the complications, Does a Monteggia variant lesion result in a poor functional outcome? (0/1), Level 1 The radial head dislocation may not be apparent and will possibly be missed if the elbow is not included in the radiograph. Bado initially described and classified these injuries. 1949 Nov. 31B (4):578-88, illust. AP and lateral radiographs reveal a proximal ulnar shaft fracture, 30 degrees apex anterior, and a radial head dislocation. (16/80), Level 5 [QxMD MEDLINE Link]. Fractures of the shafts of the radius and ulna. Bado [1] classification in Monteggia fracture-dislocations and - Giovanni Monteggia (1814) first described frx of proximal 1/3 of ulna in association w/ Thank you. Monteggia described a fracture of the proximal third of the ulna with anterior dislocation of the radial head from both the proximal radioulnar and radiocapitellar joints. JAMA 1940;115:1699-1705. Forty-eight patients who had been followed for a minimum of two years (average, 6.5 years; range, two to fourteen years) were identified. [11, 12] Of the Monteggia fractures, Bado type I has been reported to be the most common (59%), followed by type III (26%), type II (5%), and type IV (1%). (1/8), Undecided Galeazzi fracture: Distal radial shaft fracture with associated distal radio-ulnar joint (DRUJ) dislocation Special Investigations Imaging '2 views and 2 joints': Always get a minimum of two views (AP and LAT) that include the joint above and below the injury (two joints). Whenever a fracture of a long bone is noted, the joints above and below should be evaluated with radiographs in orthogonal planes (planes at 90 angles to each other). Problems with the elbow related to fractures of the coronoid process and the radial head, which are common with Bado type-II Monteggia fractures, remain the most challenging elements in the treatment of these injuries. [QxMD MEDLINE Link]. Soni JF, Valenza WR, Pavelec AC. A 12-year-old male sustains an ulnar fracture with an associated posterior-lateral radial head dislocation. If not diagnosed at an early stage, these lesions can gradually lead to forearm deformities and dysfunction, finally resulting in neglected Monteggia fracture. Evaluation of outcome of corrective ulnar osteotomy with bone grafting and annular ligament reconstruction in neglected monteggia fracture dislocation in children. The records concerning ten consecutive years of experience with Monteggia fractures in adult patients at a level-one trauma center were retrospectively reviewed.
