Background: Monteggia fracture-dislocation is rare in children. Various reports attest to its rarity, while recording the many variant of this injury. It is, therefore, easy to miss the diagnosis in the absence of proper clinical examination and radiographs. Case Report : This report highlights two rare variants of Monteggia fracture-dislocation seen in children. The first case was a 12-year old girl alleged to have fallen from a 15- feet tall tree and sustaining a combined type III Monteggia injury with ipsilateral Type II Salter-Harris injury of distal end radius with a metaphyseal fracture of the distal third of the ulna. The second case was a 13-year old who had sustained a closed fracture of atypical Type I Monteggia hybrid lesion, in a road traffic accident. Conclusion: This report highlights the rare variants of Monteggia fracture dislocation which could have been missed without proper clinical examinations and radiographs.

Child ; Humans ; Monteggia's Fracture

The anterior interosseous nerve innervates the flexor pollicis longus, the flexor digitorum profundus and the pronator quadratus. There are no sensory fibers from the anterior interosseous nerve leading to the skin. Paralysis of the anterior interosseous nerve that accompanies a Monteggia fracture has rarely been reported, and incomplete paralysis of the anterior interosseous nerve has almost not been reported. We experienced a patient with incomplete anterior interosseous nerve palsy involving the flexor pollicis longus as a complication of a Monteggia fracture. The paralysis of the flexor pollicis longus recovered 4 months after the surgery for the Monteggia fracture.

PURPOSE: This study compares the mechanism of injury and the treatment outcomes in children and adults with Monteggia fractures. MATERIALS AND METHODS: 30 patients with Monteggia fractures were treated. There were 14 children with an average age of 8.6 years and 16 adults with an average age of 36.2 years. The results are based on a review of the clinical records and the initial radiographs combined with a follow-up examination. RESULTS: Pediatric Monteggia fractures were almost always found to be the result of low energy trauma (86%), but in adults, these fractures were most often found to be result of high energy trauma (88%). There were high prevalence of type III fractures with concomitant posterior interosseous nerve injury in the children. There were 7 serious complications in the adults. CONCLUSION: The clinical outcomes of Monteggia fracture in children were satisfactory as compared to that in adults. Yet, we recommend cautiously diagnosing and treating this injury in children because most type III fractures were accompanied by posterior interosseous nerve injury.

OBJECTIVETo investigate the effects of closed reduction and ulna intramedullary nail fixation for the treatment of fresh Monteggia fractures of Bado type I and II in children.

METHODSTwenty-three children patients with Monteggia fracture during July 2010 to September 2013 were treated by closed reduction and ulna intramedullary nail fixaion including 18 boys and 5 girls with an average age of 9.3 years old ranging from 6 to 13 years old. Among them,15 cases were Bado type I and 8 cases were Bado type II. There were 9 cases with radial nerve injury. The operation time,the recovery of nerve injury, the fracture healing and the function of elbow were observed and recorded.

RESULTSAll patients were followed up for 6 to 24 months (12 months on average). All patients were obtained bone healing. According to Anderson standard, at the final follow-up, 20 cases got excellent result, 2 cases got good result, and one case got fair result.

CONCLUSIONTreatment of the fresh Monteggia fractures in children by closed reduction and ulna intramedullary nail fixation has advantages of simple operation, less trauma and good results.

OBJECTIVEMonteggia fracture dislocation equivalent, though already described by Bado, is still an unclassified entity. We aimed to retrospectively analyze 18 cases of Monteggia variants and discuss the injury mechanisms, management, and outcome along with a review of the literature.

METHODSA retrospective record of Monteggia fracture dislocation (2003-2008) was reviewed from medical record department of our institute. Classic Monteggia fracture dislocation, children below 12 years or adults over 50 years, as well as open grade II and III cases were excluded from this study. Monteggia variant inclusion criteria included fracture of the proximal ulna together with a fracture of the radial head or neck and skeletal maturity. Totally 26 patients were identified with Monteggia variants and 18 were available for follow-up, including 11 males and 7 females with the mean age of 35 years. The ulna fracture was treated by compression plating along with tension band wiring. Radial head/neck was reconstructed in 12 patients while excised in 6 patients.

RESULTSFollow-up ranged from 1-4 years, mean 2.6 years. Patients were assessed clinicoradiologically. Mayo Elbow Performance Score was employed to assess the outcomes. At final follow-up, the results were excellent in 10 patients, good in 4, fair in 2 and poor in 2. Mean range of motion of the elbow was 20 degree 116 degree, 50 degree and 55 degree for extension, flexion, pronation and supination, respectively. Two patients had complications in the form of heterotopic ossification and stiffness of the elbow. One nonunion ulna, primarily treated by tension band wiring, was managed by refixation with locking reconstruction plate and bone grafting. Bone grafting was only required in this patient for nonunion. Another patient had implants removed on his request. The results in our series closely correlated with extent of intraarticular damage, coronoid fracture and comminuted fractures.

CONCLUSIONSMonteggia fracture dislocation equivalents are rare injuries and pre-surgery recognition by radiographs and 3-D CT helps make optimal plan. The poor results usually relate to intraarticular damage, coronoid fractures and comminution of the ulna and radial head fractures.

In 1814, Giovanni Battista Monteggia first described two cased of fracture of proximal third of ulna with a dislocation of radial head, and this combined injury is now known as the Monteggia fracture. Despite its rarity, the importance of early recognition of dislocated radial head and correct treatment has been emphasized. Eight cases of Monteggia fracture were studied from March, 1984 to June, 1987. The results are as follows 1. Male patients were six and female were two. 2. The frequent cause of injury was fall down in four cases. 3. Bado type I accounted for 50%, type II for 12.5% and type III for 37.5%. 4. The level of ulna fracture was above upper one third of ulna in seven. 5. The common direction of dislocated radial head was anterior. 6. Two children and two adults were managed by closed reduction. 7. The results (by Bruce et al. criteria) were 3 excellent, 2 good, 1 fair and 2 poor. Four ulna fractures in adult were treated by open reduction and internal fixation using a semitubular plate.

PURPOSE: To evaluate the clinical outcome of silicone radial head prosthesis for treatment of comminuted radial head fractures. MATERIALS AND METHODS: Seven patients who had taken a radial head replacement with a silicone prosthesis from November 2001 to April 2004 were enrolled in the study. Mean age was 49.1 years old when they sustained a fracture of the radial head or neck. There were two Mason type III fractures and five Mason type IV fractures. Associtated injuries were a variant of Monteggia fracture, Essex-Lopresti injuries and a capitellum fracture. Mean follow-up was 20.3 months. The clinical outcome was analized by Mayo Elbow Performance Index. RESULTS: Overall outcome was that two cases were excellent, four cases were good and one case was fair. There were complications which included limitation of motion, radioulnar synostosis and proximal migration of radius. CONCLUSION: The silicone radial head prosthesis was found to be recommendable treatment option for patients with Mason type III and IV radial head fractures which were difficult to be reconstructed.

PURPOSE: To adequately diagnose Monteggia fracture which is frequently misdiagnosed at initial visit and to suggest appropriate treatment options according to the interval between initial trauma and final diagnosis. MATERIALS AND METHODS: We analyzed retrospectively 17 Monteggia fractures in children, who had been treated from May 1993 to August 1998, with complete radiologic data, medical records and adequate follow-up period. RESULTS: In 17 cases, six (35.3%) had inadequate diagnosis initially and the others (11 cases) were diagnosed adequately. Eleven cases diagnosed within 48 hours after initial injury were treated with closed reduction. Three cases diagnosed at more than 6 weeks after initial injury were treated with open reduction, ulnar osteotomy and annular ligament reconstruction. Two cases diagnosed at 3 weeks after initial injury were treated with only ulnar osteotomy followed by closed reduction of radial head. One refused treatment. All patients except one who refused treatment, had favorable clinical outcome in medium-term follow up. CONCLUSION: Monteggia fracture must be suspected in children, if there was noted ulnar fracture or radial head dislocation alone is noted. Within 3 weeks after trauma, single corrective osteotomy with closed reduction of the radial head was considered enough for treatment. At more than 6 weeks after trauma, open reduction, ulnar osteotomy and annular ligament reconstruction were needed in our study.

Elbow dislocation with concomitant diaphyseal fractures of radius and ulna has been reported rarely. This injury could be included in Monteggia equivalent lesions based on the mechanism of injury, radiographic pattern and method of treatment as described by Bado. We report a rare case of Monteggia equivalent lesion in an adult with unclear mechanism of injury. The possible mechanism of injury, its management and the follow-up results were described. An attempt to solve the controversy regarding whether labeling it as type 1 or type 2 was made.
