Tamponade following sternoclavicular dislocation surgical fixation

Traumatic posterior sternoclavicular joint dislocation - Current aspects of management

The posterior sternoclavicular joint dislocation is a rare and potentially life-threatening injury, as massive haemorrhage can occur at the time of trauma, during reduction manoeuvres and drilling. These injuries are rare and a collective experience of managing them is of paramount importance. We present our multidisciplinary experience of managing several of these injuries in our centre, with learning points we have identified. Assessment should include Computerised Tomography Angiography (CTA) to assess the anatomy of the joint including the proximity to the underlying innominate vein and to identify any bleeding. Both closed reduction and open reconstruction have the potential for massive haemorrhage which can be controlled successfully with direct access to the underlying vessel. We recommend that all reductions should be performed in the presence of a cardiothoracic surgeon who can gain vascular control in the head, neck, and thorax. In specific high-risk cases, pre-emptive venous catheterisation can also be considered. We recommend that a discussion and rehearsal for intra-operative bleeding should be undertaken with the whole theatre team, with roles assigned pre-emptively and to allow identification of any deficiencies in staff expertise or equipment. Of the five recent cases managed in our centre one patient had a closed reduction and four had open reductions. Success of closed reductions within 48 h is high and these can be attempted up to 10 days after injury. Our patient undergoing closed reduction had a favourable outcome and returned to professional rugby at five months. Open reduction was performed in a physeal fracture as there was a delay to surgery and callus had begun to form and had the potential to adhere to the underlying vessel. In this case we performed open reduction and stabilised with tunnelled suture fixation. Our preferred method of reconstruction uses a palmaris graft with internal figure of eight bracing. One patient had a subsequent fracture of the medial clavicle around the drill holes that healed without further intervention. Despite good reduction and stability achieved following palmaris reconstructions, two patients are experiencing ongoing symptoms of globus and one with voice change without any objective underlying cause.

Posterior Sternoclavicular Dislocation: Do We Need "Cardiothoracic Backup"? Insights From a National Sample

OBJECTIVES

To describe the incidence of and risk factors for vascular injury associated with P-SCD.

METHODS

We used data from the HCUP-NIS from 2015 to 2016 and defined a cohort of patients with sternoclavicular dislocation (SCD) using ICD-10-CM diagnosis codes. We further isolated a subset with P-SCD. We describe the incidence of thoracic vascular injury, demographics, and injury severity score in this cohort.

RESULTS

Of an estimated 550 patients who had SCD, 140 (25%) were identified as having a P-SCD. No vascular injuries occurred in the P-SCD cohort. Among all patients with SCD, <2% of patients had a vascular injury, all of whom had an injury severity score ≥15, independent of the vascular injury itself. Among patients with an isolated P-SCD injury (55), overall length of stay was 1.8 days and total charges averaged $29,724.45. There was no mortality among patients with isolated P-SCD.

CONCLUSIONS

Here, we report no vascular injuries in the largest known series of P-SCD. Among all patients with SCD, vascular injury was rare, occurring only in severely polytraumatized patients. The recommendation for routine involvement of cardiothoracic surgeons in all cases of P-SCD should be re-examined.

Total Endovascular Repair of Post-Trauma Ascending Aortic Pseudoaneurysm and Secondary Superior Vena Cava Syndrome

BACKGROUND

Clavicular fracture or sternoclavicular luxation is observed in 10% of all polytrauma patients and is frequently associated with concomitant intrathoracic life-threatening injuries. Posterior sternoclavicular luxation is well known to induce underlying great vessels damage. The gold standard treatment usually is a combined orthopedic and cardiovascular surgical procedure associating vascular repair, clavicular open reduction, and internal fixation.

METHODS

A 59-year-old wheelchair ridden, institutionalized woman, known for psychiatric disorder, severe scoliosis, malnutrition, and chronic obstructive pulmonary disease was admitted in our hospital for chronic chest pain 3 months after a stairway wheelchair downfall. A thoracic computed tomography (CT) scan revealed a voluminous ascending aortic pseudoaneurysm (63 × 58 mm, orifice 5 mm) consecutive to perforation following posterior sternoclavicular luxation. The patient refused all therapies and was lost to follow-up. Six months later, she was readmitted for a symptomatic superior vena cava syndrome. Thoracic CT scan revealed pseudoaneurysm growth with innominate vein thrombosis and superior vena cava subocclusion. Pseudoaneurysm orifice was stable. In the presence of symptoms with massive facial edema and inability to open her eyelids, the patient accepted an endovascular treatment.

RESULTS

The procedure was performed under general anesthesia using both fluoroscopic and transesophageal echocardiographic guidance. Through a femoral arterial access, a 10-mm atrial septal defect occluder device was used to seal successfully the pseudoaneurysm orifice. The superior vena cava was then opened with a 26-mm nitinol high radial force stent through a femoral venous access. Postoperative course was uneventful. At 3-month follow-up, the patient remains symptom free and a CT scan confirmed pseudoaneurysm thrombosis and superior vena cava permeability.

CONCLUSION

Post-traumatic sternoclavicular posterior luxation is a cause of great vessels and ascending aorta injuries. Minimally invasive endovascular approaches can be considered to treat vascular injuries and their consequences, especially in elderly patients and those at high risk for surgery.

Outcomes and complications following graft reconstruction for anterior sternoclavicular joint instability

PURPOSE

Publications describing tendon graft reconstruction for anterior sternoclavicular joint (SCJ) instability are rare and usually refer to small patient numbers. The aim of this study was to systematically review the literature regarding outcomes and complications following tendon graft reconstruction techniques for anterior SCJ instability.

METHODS

An online database was systematically searched to identify studies on graft reconstruction for anterior SCJ instability. Reported outcome scores were graded as excellent, good, fair and poor to summarize the study results. All reported complications were recorded.

RESULTS

Five articles with a total of 80 patients met the inclusion criteria. Reported outcomes were excellent in 10 %, good in 89 % and fair in 1 %. Recurrent instability was found in 10 % of the patients, and 5 % underwent revision surgery due to persistent impairment of shoulder function related to SCJ instability or osteoarthritis.

CONCLUSION

Surgical stabilization techniques for the SCJ using autologous tendon grafts have shown to be safe and reliable and make better patients' pain situation and shoulder function. However, a certain amount of impairment might persist, which needs to be discussed with patients. Severe complications were rare and revision rates were as low as 5 %. Therefore, graft reconstruction techniques should be considered for patients with chronic anterior SCJ instability after a course of failed conservative treatment. This study is valuable for clinicians in daily clinical practice when dealing with this difficult-to-treat pathology and can help surgeons to better predict the clinical outcomes and complications following SCJ graft reconstruction. It should, however, not lead to underestimation of the potential risks of the procedure.

[Fracture-separation of the medial clavicular epiphysis: about 6 cases and review of the literature]

This study aims to describe the epidemiological characteristics and the different anatomo-clinical entities of the fracture-separation of the medial clavicular epiphysis but also to relate the morphological and functional results of bloody reduction followed by osteosuture using non absorbable thread. Five boys and one girl (mean age 14 years) showed a closed and isolated shoulder girdle trauma. Clinical examination and medical imaging, especially CT scan, allowed the diagnosis of epiphyseal separation and to classify the degree of medial clavicular epiphysiseal ossification indicating the direction of displacement as well as the nature of displacement according to the Salter-Harris classification. Bloody reduction followed by osteosuture using non absorbable thread (No. 1 decimal) was performed in 3 patients. One patient underwent cross-pinning the two younger patients were treated orthopedically. The displacement of the clavicle stump was anterior in 3 patients and retro-sternal in 3 patients. Posterior forms were complicated by odynophagia (n = 2) and asymptomatic compression of the subclavian vein (n = 1). One of the posterior forms was associated with an ipsilateral fracture of the medial one third of the clavicle. Consolidation was achieved in all patients with preservation of shoulder mobility. The fracture-separation of the medial end of the clavicle mimes clinically and radiologically the sternoclavicular dislocation. It can be serious because of the risk of visceral and vascular compression in its posterior form. Tomdensitometry is irreplaceable for an accurate diagnosis. Our preference is for bloody reduction followed by osteosuture using non metallic thread.

Death Due to Intra-aortic Migration of Kirschner Wire From the Clavicle: A Case Report and Review of the Literature

Migration of orthopedic fixation wires into the ascending aorta though a rare occurrence can have devastating consequences. Therefore, prompt recognition, with immediate and cautious retrieval of the implant is paramount in averting these complications.We present a case of a 5-year-old boy with the intra-aortic migration of a K-wire used for the treatment of a right clavicle fracture. He was transferred to us with a history of syncope, chest pain, and shortness of breath 7 days after K-wire placement, which was performed at another hospital. On CT scan, the wire was found to be partially inside the ascending aorta, which was associated with massive hemopericardium and cardiac tamponade. The patient was taken up for emergency surgery for the removal K-wire and for the management of cardiac temponade. However, the patient developed cardiac arrest during the induction of intravenous anesthesia and endotracheal intubation. The K-wire was retrieved from the thorax via thoracotomy. However, the patient died 10 days after the surgery.As the migration of wires and pins during orthopedic surgery can cause potentially fatal complications, these should be used very cautiously, especially for percutaneous treatment of shoulder girdle fractures. The patients with such implants should be followed frequently, both clinically and radiographically. If migration occurs, the patient should be closely monitored for emergent complications and the K-wire should be extracted immediately.

Repair of Unstable Posterior Sternoclavicular Dislocation Using Nonabsorbable Tape Suture and Tension Band Technique: A Case Report with Good Results

Posterior sternoclavicular joint dislocation (PSCJD) is quite a rare condition. Nearly half of the closed reduction attempts fail due to various reasons. In this paper, we present a 25-year-old male patient who was admitted to the emergency department in our hospital after having a motor-vehicle accident. It was decided to do PSCJD after physical and imaging studies. Following necessary preparations, closed reduction was attempted with abduction-traction maneuver under general anesthesia; however, adequate stabilization could not be achieved and redislocation was detected during control. Therefore, joint was stabilized with tension band technique using 6 mm polyamide nonabsorbable type suture during open reduction. Painless and complete range of motion in shoulder was achieved at the postoperative 10th week.

Pediatric Posterior Sternoclavicular Joint Injuries

Posterior sternoclavicular joint injuries are increasingly diagnosed in children and young adults. Most of these injuries are the result of indirect mechanisms, typically lateral compression, with a posterior-to-anterior force applied to the shoulder during sports. Less frequently, these injuries are caused by direct impact on the medial clavicle, which can occur in rollover motor vehicle accidents, or may represent atraumatic instability. In patients younger than 25 years, physeal separation is more common than true dislocation. Theoretically, these patients have increased remodeling potential. Reduction is recommended to prevent and/or manage the compression of mediastinal structures, which can lead to life-threatening injury. Open surgical stabilization is the preferred treatment for acute and chronic retrosternal injuries. A thoracic or trauma surgeon should be available during stabilization in the rare event of potentially life-threatening hemorrhage after reduction. Outcomes have been largely successful, with pain-free, unrestricted range of motion and return to activity.

Safe surgical technique: reconstruction of the sternoclavicular joint for posttraumatic arthritis after posterior sternoclavicular dislocation

Posttraumatic sternoclavicular arthritis related to chronic ligamentous instability after posterior sternoclavicular dislocation represents a rare but challenging problem. The current article in the Journal’s “Safe Surgical Technique” series describes a successful salvage procedure by partial resection of the medial clavicle and ligamentous reconstruction of the sternoclavicular joint with a figure-of-eight semitendinosus allograft interposition arthroplasty.

Management of sternoclavicular dislocation in young children: considerations about diagnosis and treatment of four cases

The records of 4 children of under 14 years of age treated at our institution for traumatic sternoclavicular dislocation (SCJ) were reviewed. Closed reduction in posterior SCJ after computed tomography (CT) was successful as immediate procedure. For anterior SCJ instability, open reduction and SCJ reconstruction obtained satisfactory results. Conservative treatment of SCJ subluxation for asymptomatic children was sufficient. Radiographs in "serendipity view" were useful for confirming reduction and stability in children. No postoperative CT was needed for this purpose. Closed reduction in posterior SCJ dislocation and surgical treatment in anterior SCJ dislocation in young children can provide stability and a satisfactory return to a normal function, but with some limitation when intense or competitive shoulder motion is required during sport. Young children and parents should be aware about this possibility. Conservative treatment of SCJ subluxation for asymptomatic children is useful. Reflection is required regarding the correct imaging examination after treatment to check stable reduction in a SCJ injury.

A simple surgical treatment for acute traumatic sternoclavicular dislocation

Sternoclavicular lesions may sometimes require surgery. Many techniques have been described and they appear to be very demanding. We describe a simple technique using two screws and a strong suture (Arthrex Inc. Naples. FL 34108 USA). Level of evidence; Level IV, Case Series, Treatment Study.

Reconstruction of the sternoclavicular joint in active patients with the figure-of-eight technique using hamstrings

BACKGROUND

Dislocations of the sternoclavicular joint are rare injuries caused by massive forces applied to the joint. A high rate of complications has been reported following this injury emphasizing the importance of an accurate diagnosis and therapy.

METHODS

We report a series of patients with chronic anterior or posterior sternoclavicular instability treated with figure-of-eight gracilis- or semitendinosus-tendon reconstruction. Tendon grafts were collected from the patient's ipsilateral knee. Preoperative and postoperative DASH scores were compared to evaluate the outcome.

RESULTS

Six patients (mean age, 22 years; range 15-46; male = 3; female = 3) were included. The patients sustained an isolated dislocation of the sternoclavicular joint resulting from a high-energy trauma. Anterior instability was observed in 3 patients, posterior instability in 2 patients and the remaining patient showed multidirectional instability. The mean time from injury to operation was 8 months (range, 4-33). The semitendinosus tendon was used in 4 patients, the gracilis tendon in 2 patients, respectively. Follow-up examination was after 22 months (range, 14-34). The DASH score improved from 54.3 points (range, 45.7-68.8) preoperatively to 28.8 points (range, 25.8-34.5) postoperatively. All patients returned to full activity without limitations including competitive contact sports.

CONCLUSION

Stabilization of the sternoclavicular joint with the figure-of-eight technique seems to be a feasible alternative for young and active patients with remaining instability following conservative treatment.
