Posterior interosseous nerve palsy associated with neglected pediatric Monteggia fracture-dislocation: A case report

IntroductionThe main goal of the treatment is the anatomical reduction of the ulna fracture and the radial head dislocation in acute and chronic Monteggia cases. Acute pediatric Monteggia lesions are generally treated non-surgically; however, the treatment of chronic Monteggia is challenging. The aim of this article is to share our experiences about treatment of neglected Monteggia lesion.Presentation of caseA 6-year-old girl who underwent a surgery in our clinic for a missed Bado type-III Monteggia fracture-dislocation of the right elbow with concomitant posterior interosseous nerve (PIN) palsy, which resolved spontaneously after the operation. The operation consisted of open reduction of the radial head, transverse ulnar osteotomy and fixation with an intramedullary Kirchner wire, and annular ligament repair without exploring PIN. The patient was seen in routine follow-up periods until the postoperative first year using plain radiographies. At 16th week follow-up, all functions of the PIN were returned. At first-year follow-up, full range of elbow motion was observed; plain radiographies showed radiocapitellar joint congruency, and Mayo Elbow Performance Index was one hundred.DiscussionTreatment planning for chronic, neglected or missed Monteggia fractures is challenging. There is no consensus about the definitive treatment in the literature.ConclusionWe recommend anatomic and stable restoration of radiocapitellar joint by correcting ulna deformity. Radiocapitellar fixation and PIN exploration may not be necessary in all neglected Monteggia lesions.     

Missed Monteggia fracture in children: Is annular ligament reconstruction always required?

Background:

Chronic (neglected) radiocapitellar joint dislocation is one of the feared complications of Monteggia fractures especially when associated with subtle fracture of the ulna bone. Many treatment strategies have been described to manage chronic Monteggia fracture and the need for annular ligament reconstruction is not always clear. The purpose of this study is to highlight the management of missed Monteggia fracture with particular emphasis on utility of annular ligament reconstruction by comparing the two groups of patients.

Materials and Methods:

In a prospective study 12 patients with mean age of 7.4 years, who presented with neglected Monteggia fractures, were studied. All children underwent open reduction of the radiocapitellar joint. Five children (Group A) were treated with angulation-distraction osteotomy of ulna and annular ligament reconstruction and six cases (Group B) required only angulation-distraction osteotomy of ulna without ligament reconstruction. In one case an open reduction of the radiocapitellar joint was sufficient to reduce the radial head and this was included in Group B. The gap between injury and presentation was from 3 months to 18 months (mean 9 months). Ten patients were classified as Bado I, and one each as Bado II and III respectively. We used the Kim''s criteria to score our results.

Result:

The mean follow-up period was 22 months. All ulna osteotomies healed uneventfully. The mean loss of pronation was 15 degree in Group A and 10 degree in Group B. Elbow flexion improved from the preoperative range and no child complained of pain, deformity and restriction of activity. The elbow score was excellent in 10 cases, and good in two cases.

Conclusion:

Distraction-angulation osteotomy of the ulna suffices in most cases of missed monteggia fracture and the need for annular ligament reconstruction is based on intraoperative findings of radial head instability.     

Korrektur von veralteten Monteggia-Verletzungen im Kindes- und Jugendalter

While adequately treated acute Monteggia lesions have a good prognosis, results in neglected Monteggia fractures are varied. Outcomes improved as a consequence of a better understanding of the pathology of the elbow joint. Persistent malposition of the radial head leads to maldevelopment of the radioulnar and radiohumeral joints. The following parameters have a crucial influence on prognosis of neglected Monteggia fractures: morphological changes of the elbow joint, duration of dislocation and the age of the patient. An individual treatment concept is necessary for an adequate correction of the complex malformations. Concerning the indications for corrective surgical procedures it is important to estimate whether they are advantageous. Not every dislocation of the radial head has to be treated and sometimes the spontaneous development can be functionally and symptomatically better than an unsuccessful attempt at correction. This publication presents the criteria which are necessary for a correct treatment of neglected Monteggia lesions. The key procedure of correction is osteotomy of the ulna which can range from simple angulation up to complex multidimensional corrections. The results of treatment of neglected Monteggia lesions depend strongly on the surgeon’s experience and the technique chosen.     

Surgical treatment of missed Monteggia lesions in children

Purpose The treatment of an unrecognized Monteggia lesion continues to pose a therapeutic challenge, as evidenced by the variety of surgical techniques described. Moreover, there are high complication and redislocation rates following surgery. This report concerns a surgical technique to reduce a chronic dislocation of the radial head utilizing an ulnar osteotomy and internal fixation. Methods Six consecutive cases of missed Monteggia lesions were treated in our institution between August 2001 and September 2003. Patient mean age was 6.5 (range 4–8) years, and the mean interval between injury and surgical procedure was 17 (range 1–49) months. Surgery consisted of an ulnar osteotomy with angulation and lengthening, bone grafting at the osteotomy site, and internal fixation. Open reduction of the radial head, repair or reconstruction of the annular ligament or temporary fixation of the radial head with a transarticular wire was not undertaken. Cast immobilization with the forearm in neutral rotation was maintained for 2 weeks. Results There was one case of nonunion. At an average follow-up of 3 (range 1.5–4.4) years, all patients had regained painless function of the forearm, good range of elbow and forearm motion, and maintenance of the radial head reduction. Conclusions Both angulation and elongation of the ulna are required to allow for reduction of the radial head. We do not see any indication for procedures directed at the radio-capitellar joint.

Treatment of the missed Monteggia fracture in the child.

Eight children with missed Monteggia fracture-dislocations are described. Seven had reconstructive surgery which included resection of scar tissue from the radiohumeral joint, proximal ulnar osteotomy, reduction of the radial head and reconstruction of the annular ligament. One had excision of the radial head. Excellent results were obtained in patients under ten years of age, up to four years after the initial injury.

Detrimental effects of overstuffing or understuffing with a radial head replacement in the medial collateral-ligament deficient elbow

BACKGROUND: Comminuted radial head fractures associated with an injury of the medial collateral ligament can be treated with a radial head implant. We hypothesized that lengthening and shortening of the radial neck would alter the kinematics and the pressure through the radiocapitellar joint in the medial collateral ligament-deficient elbow. METHODS: The effects of lengthening (2.5 and 5 mm) and shortening (2.5 and 5 mm) of the radial neck were assessed in six human cadaveric upper extremities in which the medial collateral ligament had been surgically released. The three-dimensional spatial orientation of the ulna was recorded during simulated active motion from extension to flexion. Total varus-valgus laxity and ulnar rotation were measured. Radiocapitellar joint pressure was assessed with use of pressure-sensitive film. RESULTS: Radial neck lengthening or shortening of >/=2.5 mm significantly changed the kinematics in the medial collateral ligament-deficient elbow. Lengthening caused a significant decrease (p < 0.05) in varus-valgus laxity and ulnar rotation (p < 0.05), with the ulna tracking in varus and external rotation. Shortening caused a significant increase in varus-valgus laxity (p < 0.05) and ulnar rotation (p < 0.05), with the ulna tracking in valgus and internal rotation. The pressure on the radiocapitellar joint was significantly increased after 2.5 mm of lengthening. CONCLUSIONS: This study suggests that accurate restoration of radial length is important and that axial understuffing or overstuffing of the radiohumeral joint by >/=2.5 mm alters both elbow kinematics and radiocapitellar pressure. CLINICAL RELEVANCE: This in vitro cadaver study indicates that a radial head replacement should be performed with the same level of concern for accuracy and reproducibility of component position and orientation as is appropriate with any other prosthesis.     

The role of biceps loading and muscle activation on radial head stability in anterior Monteggia injuries: An in vitro biomechanical study

IntroductionLittle evidence-based information is available to direct the optimal rehabilitation of patients with anterior Monteggia injuries.Purpose of the StudyThe aims of this biomechanical investigation were to (1) quantify the effect of biceps loading and (2) to compare the effect of simulated active and passive elbow flexion on radial head stability in anterior Monteggia injuries.Study DesignIn vitro biomechanical study.MethodsSix cadaveric arms were mounted in an elbow motion simulator. The effect of biceps loading, simulated active and passive elbow flexion motions was examined with application of 0N, 20N, 40N, 60N, 80N, and 100N of load. Simulated active and passive elbow flexion motions were then performed with the forearm supinated. Radial head translation relative to the capitellum was measured using an optical tracking system. After testing the intact elbows, the proximal ulna was osteotomized and realigned using a custom jig to simulate an anatomical reduction. We then sequentially sectioned the anterior radiocapitellar joint capsule, annular ligament, quadrate ligament, and the proximal and middle interosseous membrane to simulate soft tissue injuries commonly associated with anterior Monteggia fractures.ResultsGreater magnitudes of biceps loading significantly increased anterior radial head translation. However, there was no significant difference in radial head translation between simulated active and passive elbow flexion except in the final stage of soft tissue sectioning. There was a significant increase in anterior radial head translation with progressive injury states with both isometric biceps loading and simulated active and passive motion.ConclusionsOur results demonstrate that anatomic reduction of the ulna may not be sufficient to restore radial head alignment in anterior Monteggia injuries with a greater magnitude of soft tissue injury. In cases with significant soft tissue injury, the elbow should be immobilized in a flexed and supinated position to allow relaxation of the biceps and avoid movement of the elbow in the early postoperative period.
