Traumatic floating clavicle: a case report and literature review

Traumatic Floating Clavicle: A Case Report and Updated Literature Review

Traumatic floating clavicle or bipolar dislocation is a rare injury. Herein, we present a case of ipsilateral sternoclavicular and acromioclavicular joint dislocation after a motorcycle accident. The patient was a 43-year-old man who presented with right shoulder pain and limited range of motion. The radiograph revealed superior displacement of the acromioclavicular joint dislocation and suspected ipsilateral sternoclavicular joint dislocation and a CT scan confirmed injuries to both the medial and lateral ends of the clavicle. Due to the patient being active and young, we considered operative treatment. The sternoclavicular joint was stabilized with FiberTape® suture (Arthrex, Naples, FL), and the acromioclavicular joint with Dog Bone™ Button (Arthrex) and suture cerclage. At the one-year follow-up, the patient reported excellent outcomes without complications. We also summarize the literature on this particular injury, including its characteristics, surgical options, and treatment outcomes.

Application of a new sternoclavicular hook plate in bipolar clavicle injuries

Objective

To evaluate the safety and effectiveness of using a new sternoclavicular hook plate combined with a shoulder locking hook plate for the treatment of bipolar clavicle injuries.

Methods

Retrospective analysis of 7 patients with bipolar clavicle injury, all-male, with a mean age of 51.1 years, who underwent a new sternoclavicular hook plate combined with a shoulder clavicular hook plate implantation.

Results

All 7 patients were fixed with a sternoclavicular hook plate combined with a repositioned shoulder locking hook plate and received 13-24 months of follow-up. There were no postoperative complications, no wound infections, and no plate or screw fractures. The mean ASES score was 94.3 ± 2.8.

Conclusion

The safety and effectiveness of a new sternoclavicular hook plate combined with a shoulder locking hook plate in the treatment of bipolar clavicle injuries.

Monopolar and Bipolar Combination Injuries of the Clavicle: Retrospective Incidence Analysis and Proposal of a New Classification System

Clavicle injuries are common, but only few case reports describe combined clavicular injuries (CCI). CCI include combinations between clavicular fractures and acromioclavicular/sternoclavicular joint dislocations (SCJD). We present the first general therapeutic recommendations for CCI based on a new classification and their distribution. A retrospective, epidemiological, big data analysis was based on ICD-10 diagnoses from 2012 to 2014 provided by the German Federal Statistical Office. CCI represent 0.7% of all clavicle-related injuries (n = 814 out of 114,003). SCJD show by far the highest proportion of combination injuries (13.2% of all SCJD were part of CCI) while the proportion of CCI in relation to the other injury entities was significantly less (p < 0.023). CCIs were classified depending on (1) the polarity (monopolar type I, 92.2% versus bipolar type II, 7.8%). Monopolar type I was further differentiated depending on (2) the positional relationship between the combined injuries: Ia two injuries directly at the respective pole versus Ib with an injury at one end plus an additional midshaft clavicle fracture. Type II was further differentiated depending on (3) the injured structures: IIa ligamento-osseous, type IIb purely ligamentous (rarest with 0.6%). According to our classification, the CCI severity increases from type Ia to IIb. CCI are more important than previously believed and seen as an indication for surgery. The exclusion of further, contra-polar injuries in the event of a clavicle injury is clinically relevant and should be focused.

Bipolar clavicular fracture on ipsilateral reverse shoulder prosthesis: Case report

•

Rare case of traumatic bipolar clavicular over an ipsilateral reverse shoulder prosthesis.

•

Open reduction and internal fixation showed satisfactory bony alignement with intact reverse shoulder prosthesis.

•

Post operative rehabilitation is of great importance, taking into consideration the deltoid musculature wish should be addressed for shoulder strengthening over prosthesis.

Background

Bipolar clavicular fractures are extremely rare with no consensus on management. No previous cases of bipolar clavicular fracture on an ipsilateral reverse shoulder prosthesis have been reported.

Case presentation

We report a case of a 78y.o female patient with left bipolar clavicular fracture on ipsilateral reverse shoulder prosthesis, associated with multiple ribs fracture, that was treated with open reduction and internal fixation using k-wires and endobutton for the lateral part, while as the medial part was fixed with plate and screws.

Conclusions

Any patient with a clavicle fracture, with a history of sequential forces to the clavicle, a bipolar injury should always be suspected. Attention should be given if any implants are present on the ipsilateral side of the injury, which could affect surgical planning and outcome.

Ipsilateral sternoclavicular joint anterior dislocation with fracture of the mid shaft of the clavicle

Even though fractures of the clavicle are very common but fracture of the shaft of clavicle associated with sternoclavicular joint dislocation is extremely rare. This is a case report of a 50-year old woman who met with a road accident. Radiographs revealed right mid shaft clavicle fracture with inferior angulation of fracture fragments, anterior dislocation of sternoclavicular joint. The sternoclavicular joint was stabilized with sutures whereas the midshaft fracture was managed non-operatively. In postoperative period the sternoclavicular joint was found stable whereas the shaft clavicle united completely after 6 months.

Bipolar Dislocation of the Clavicle: A Report of Two Cases with Different Injury Patterns and a Literature Review

Bipolar dislocation of the clavicle is a rare injury that is defined as a concomitant dislocation of the ipsilateral acromioclavicular joint and sternoclavicular joint. This injury is also described as a floating clavicle. Although this injury has been known for nearly two centuries, knowledge about it is limited and the treatment strategy remains controversial. Bipolar dislocation includes several combinations of both joints' injury types. We reported two patients with bipolar dislocation of the clavicle: one with an anterior dislocation and the other with a posterior dislocation of the sternoclavicular joint. After reviewing the currently available literature, we discussed these cases to highlight the necessity of a specific treatment approach that is modified based on the pattern of each joint's lesion.

A Rare Case of Bipolar Clavicle Fracture

Segmental or bipolar fractures of the clavicle generally refer to a concomitant ipsilateral distal clavicle and midshaft clavicle fracture. These injuries are exceedingly rare and are generally secondary to higher energy injuries. We report a case of a 38-year-old male who sustained a left bipolar clavicle fracture after falling from a push bike while riding recreationally which unusually involved the medial and lateral ends of the clavicle and not the midshaft as previously reported in other patients. The patient's exact fracture configuration was not immediately apparent highlighting the need for careful examination of the whole clavicle in order to not miss a bipolar fracture.

Operative Treatment of an Atypical Segmental Bipolar Fracture of the Clavicle

Introduction:

Clavicle fractures are very common, accounting for approximately 4% of all adult fractures. Segmental bipolar fractures involving the lateral and the medial ends of the clavicle are extremely rare, with only isolated cases reported in the literature. The injury mechanism is often unclear and the management of these fractures remains controversial.

Case presentation:

Here is to report a case of a segmental bipolar fracture of the clavicle with a lateral fracture and a displaced medial fracture without dislocation of the sternoclavicular joint following a low energy fall to the outstretched hand, and discuss its management.

Conclusions:

Stability of the clavicle is crucial for shoulder function and care should be taken not to miss or underestimate segmental bipolar fractures even with a low energy mechanism. Authors believe that operative treatment should be taken into consideration for displaced fractures.
