Bipolar Clavicular Dislocation

Abstract

Bipolar clavicular dislocation rarely occurs. Although referred to by several different names (panclavicular dislocation, bifocal clavicle dislocation, traumatic floating clavicle, and periarticular clavicle dislocation), knowledge regarding appropriate treatment of this condition is limited. Conservative therapy remains the gold standard in asymptomatic individuals. In younger individuals with higher functional demands, or individuals with persistent pain or instability, open reduction with internal fixation of the acromioclavicular joint has also proven successful. In situations with continued medial instability, internal fixation can be used at both the acromioclavicular joint and sternoclavicular joint.Chronic bipolar dislocation may require total claviculectomy, especially when chronic dislocation has led to nonviable acromioclavicular and sternoclavicular joint viability. This article presents a chronic case of bipolar dislocation treated by complete claviculectomy.

A four-year-old neglected traumatic bipolar clavicular dislocation: a case report

“…9,12 This condition has also been referred to as bifocal clavicular dislocation, floating clavicle, periarticular clavicle dislocation, and panclavicular dislocation. 2 Porral 11 described the first case of bipolar clavicular dislocation in 1831, and since then, a scarce number of reports have been published. Therefore, there is limited knowledge of the diagnosis, the optimal treatment, and the prognosis, especially in chronic cases.…”

Traumatic Floating Clavicle: A Case Report and Literature Review

“…Synonyms for this injury include complete dislocation [1], bipolar dislocation [2], panclavicular dislocation [3], bifocal clavicular dislocation [4], and traumatic floating clavicle [5]. These injuries are rare, and there has been no definitive incidence of these injuries reported in the literature.…”

“…This rare injury refers to simultaneous injuries to the medial and lateral end of the clavicle and has been called variously—complete dislocation [1], bipolar dislocation [2], panclavicular dislocation [3], bifocal clavicular dislocation [4], and traumatic floating clavicle [5]. Bipolar fracture dislocations of the clavicle are rare injuries, usually the result of high-energy trauma [4, 6, 7].…”

“…Since the original description by Porral in 1831 [8], only a handful of individual case reports and the case series of Beckman [1] and Sanders et al [9] have been reported in the literature. Management of these injuries has remained controversial ranging from nonoperative [10] to aggressive surgery [11]—even to the extent of total clavicle excision for a neglected dislocation [2]. It is noted through a careful review of the literature that surgical options have been preferred for younger and more active patients whereas the older and more sedentary patients were managed nonoperatively [4, 5].…”

Case Report: Floating-clavicle from the 17th Century: The Oldest Case?

“…Each author certifies that his or her institution approved or waived approval for the reporting of this case and that all investigations were conducted in conformity with ethical principles of research. increased the frequency of this injury, most reports have been based on single cases [1,2,5,7,8,11,12,17,27]. Only five studies presented multiple cases (four cases published by Rockwood [25] in 1984, six cases by Sanders et al [26] in 1990, two cases by Le Huec et al [18] in 1998, three cases by Dieme et al [10] in 2007, and two cases by Schemitsch et al in 2011 [28]).…”
