Surgical fixation of traumatic sternal manubrium dislocation and right-sided rib fractures following a motorcycle accident.

This brief report discusses the diagnosis, management and surgical intervention of a man in his 30s presenting with a rare traumatic sternal manubrium dislocation following a motorcycle crash, accompanied by multiple concomitant rib fractures. The severity and complexity of the patient's injuries necessitated an operative approach for his sternomanubrial dislocation, emphasising the importance of multidisciplinary coordination, accurate diagnosis and prompt surgical intervention. The report provides valuable insights into the successful application of open reduction and internal fixation with plating in a real-world setting, which resulted in positive patient outcomes, despite the rarity and severity of this type of trauma. It further underscores the need for additional research to advance best practices for managing traumatic sternal manubrium dislocations in the context of high-impact injuries.

Resection of the entire first rib for giant osteochondroma by trans manubrial approach: a case report and review of the literature.

BACKGROUND: First rib tumors are extremely rare. Its compression of neurovascularity can easily lead to severe complications such as thoracic outlet syndrome, so early surgical resection is crucial. However, there is no standardized approach to surgery. CASE PRESENTATION: A previously healthy 18-year-old Chinese male undergoes a chest computed tomography (CT) scan that incidentally reveals a raised calcified mass on the right first rib, which is most likely an osteochondroma when combined with magnetic resonance imaging (MRI). We achieved excellent results with resection and thoracic reconstruction by adopting an inverse L-shaped incision in the anterior chest and a longitudinal split of the sternum. CONCLUSIONS: Our practice provides great reference for the surgical management of first rib tumors.

Manubriectomy made easy.

Bone metastasis is the most common form of distant metastasis encountered within the breast cancer population. Surgical resection of bone metastases is a curative treatment option in patients who present with an isolated solitary lesion and no other associated disease. This decision is typically made following a multidisciplinary discussion. Patients can also be put forward for surgical excision of bone metastases following inadequate response to chemotherapy or radiotherapy.  With tumours located in the manubrium of the sternum, surgery serves not only to resect the bone metastasis but to provide suitable chest wall reconstruction. The goal of this approach is to maintain the structural and bony stability of the chest wall as well as that of associated structures, e.g. rib insertion or articulation of the shoulder girdle. A widely utilized approach involves excising the area of metastasis within the manubrium followed by implanting a bone cement prosthesis. Titanium plates are used to fix the bone prosthesis to the sternal body inferiorly and to the remainder of the manubrium superiorly.  We present a step-by-step video tutorial for performing a lower hemi-manubriectomy in a patient with triple-negative breast cancer. Our goal is to describe the fundamental principles and surgical techniques used to perform this procedure followed by the postoperative outcomes.

Presence of manubrium-sternum joint does not assure sufficient elevation of sternum in Nuss procedure for pectus excavatum patients.

BACKGROUND: The manubrium and body of the sternum are connected by the manubrium-sternum joint (MSJ). In performing the Nuss procedure for pectus excavatum patients, the body of the sternum is elevated as the operator flips correction bars upside down. Theoretically, the presence of the MSJ should allow elevation of the sternum body. However, does the MSJ secure sufficient elevation of the sternum? This study aims to elucidate this clinical question. METHODS: Seventy-four adult pectus excavatum patients with moderate to serious deformity (with Haller Index being equal to or greater than 5) were included in the study. The MSJ was open in all patients. For 29 patients, the sternum was elevated by only bar flipping (Non-Separation Group); for 45 patients, the sternum was horizontally separated after bar flipping (Separation Group). Whether or not additional elevation for Separation Group patients results from the division was observed, and the degree of the additional elevation was evaluated. Furthermore, 74 patients subjectively evaluated postoperative pain and gave scores with a Visual Analog Scale ranging from 0 (no pain) to 10 (intolerable pain). The VAS scores were compared between the two groups. RESULTS: In the Separation Group, the sternums of all patients achieved additional elevation from sternum separation. The pain scores were lower for the Separation Group than for the Non-Separation Group. CONCLUSION: Even when the MSJ is present, horizontal separation enhances the elevation of the sternum. Furthermore, horizontal separation of the sternum reduces postoperative pain.

Right transmanubrial approach to the cervicothoracic spine with venous reconstruction.

The transmanubrial approach first reported by Grunenwald in 1997 is well-known for superior sulcus lung malignancies involving the thoracic inlet. Because an anterior approach to levels below Th2 is difficult without removing the manubrium, we used the transmanubrial approach for anterior cervicothoracic corpectomy and fusion (C7-Th3) in a patient with bilateral lower extremity paralysis due to ossification of the posterior longitudinal ligament in the cervicothoracic spine. To ensure more working space in the deep surgical field, which was hindered by a prior cardiac operation with median sternotomy and a goiter protruding into the upper mediastinal region, the right brachiocephalic vein was temporarily divided and subsequently reconstructed using bovine pericardium.

Delayed presentation of manubriosternal dislocation after thoracolumbar spondylodesis in a polytrauma patient - a case report.

BACKGROUND: Manubriosternal dislocations are a rare entity and frequently associated with thoracic spine fractures and, in minority of cases, with cervical or thoracolumbar fractures. METHODS: Our case represents a 38-year-old male who fell from a height resulting in multiple fractures, amongst others of the first lumbar vertebra. At primary survey and computed tomography scan no manubriosternal injury was apparent. After posterior stabilization of the thoracolumbar vertebrae a manubriosternal dislocation was identified and stabilized using plate-and-screw fixation. RESULTS: Clinical findings of a manubriosternal dislocation are not always obvious, allowing them to be missed at initial assessment. CONCLUSIONS: Manubriosternal dislocations can be missed at the initial investigation, even on cross-sectional imaging, and only become visible after spine stabilization because of the tight relationship between sternum and vertebrae in the thoracic cage. There is no unanimity in literature for surgical treatment of manubriosternal dislocations, although plate fixation is generally considered a safe and effective treatment option.

Heart transplantation using manubrium-sparing sternotomy for sternal re-entry.

We report a technique of heart transplantation performed by manubrium-sparing sternotomy for challenging re-entry after minimally invasive left ventricular assist device insertion. A T-shaped, manubrium-sparing sternotomy was performed using an oscillating saw up to the first intercostal space. After cardiopulmonary bypass was established via the right axillary artery and percutaneous venous cannulation of the right jugular and femoral vein, the outflow graft was ligated and divided via a left thoracotomy. All anastomoses were performed with a standard technique with an excellent exposure and outcome.

Manubrium Reconstruction.

To date, there is no standard approach for manubrial reconstruction. We had previously utilized mesh; however, this resulted in breakage, infection, and poor cosmesis. In this case series, we describe our transition to iliac wing autograft reconstruction. We examined 7 patients who underwent manubrial resection and reconstruction: 2 with mesh and methyl methacrylate and 5 with an iliac wing autograft. The outcomes of the autograft patients were overall favorable with no short-term complications or instances of breakage. We conclude that an iliac wing autograft for manubrial reconstruction is feasible and effective alternative to methyl methacrylate mesh.

Median manubriotomy for ventral access to the caudal cervical and cranial thoracic spine.

OBJECTIVE: To describe median manubriotomy to access the ventral aspect of the caudal cervical and cranial thoracic spine and report the outcomes in dogs with lesions affecting the spinal cord at C6-T2 vertebral bodies. To evaluate possible complications of this technique and clinical outcomes. STUDY DESIGN: Cadaveric study and short case series. STUDY POPULATION: Two cadavers and nine dogs with lesions affecting the spinal cord at C6, C7, T1 or T2 vertebral bodies or corresponding intervertebral spaces. METHODS: Two cadavers were used for demonstration purposes. Medical records (2013-2019) were reviewed for dogs undergoing median manubriotomy to facilitate access to the ventral aspect of C6-T2 vertebral bodies and/or corresponding intervertebral disc spaces. Data on preoperative and postoperative neurological status and diagnostic imaging, surgical technique, and complications were retrieved. RESULTS: Indications for surgery included C7-T1 disc extrusions in five dogs, caudal cervical misalignment in three dogs, and C7-T1 and T1-T2 disc protrusions in one dog. The vertebral bodies of C6 to T2 were consistently visualized after median manubriotomy. Preoperative clinical signs resolved in five dogs and improved in two dogs. One dog was euthanized for lack of improvement, and one dog died of pulmonary thromboembolism. CONCLUSION: Median manubriotomy improved the surgical access to the ventral aspect of caudal cervical and cranial thoracic spine without related complications. CLINICAL SIGNIFICANCE: Median manubriotomy can be considered in dogs undergoing ventral decompression and/or stabilization of C7-T1 and T1-T2 intervertebral disc spaces.

The transmanubrial osteomuscular-sparing approach: a valuable adjunct to the head and neck surgical armamentarium.

PURPOSE OF REVIEW: To describe and popularize the transmanubrial osteomuscular-sparing approach (TOSA) outside its original thoracic surgical field of application, based on the consideration that it could be of interest for the management of a number of head and neck cases in both elective and emergent scenarios. RECENT FINDINGS: The main advantages of TOSA compared with transclavicular techniques are its superb exposure of anatomic structures located at the level of the cervicothoracic junction, and superior postoperative aesthetic and functional outcomes. Recently, a number of studies have described the association of TOSA with other minimally invasive approaches, such as video-assisted thoracoscopic surgery and robotic hybrid approaches, with the aim of avoiding association of the transmanubrial route with anterior/posterior thoracotomies, or more extended surgeries, such as the trapdoor or hemiclamshell procedures. SUMMARY: TOSA, even though originally conceived to reduce the morbidity ensuing from classic transclavicular approaches for management of Pancoast tumors, may well play an important role in a number of head and neck surgical conditions, including those related to mediastinal goiter and thyroid cancer, management of stenosis and lesions of the thoracic trachea and esophagus, treatment of the junction between innominate, internal jugular, and subclavian veins, epiaortic arteries, thoracic duct, brachial plexus, and low sympathetic chain. Whenever comprehensive control of vascular and nonvascular structures of the upper mediastinal inlet is required, TOSA should be planned and performed by combining the expertise of cooperating professionals.

Analysis of sternal healing after median sternotomy in low risk patients at midterm follow-up: retrospective cohort study from two centres.

BACKGROUND: For low risk patients undergoing median sternotomies, no midterm follow-up studies involving sternal healing have been conducted. In this study we evaluated sternal healing in low risk patients by chest CT scan and the risk factors associated with poor healing were analyzed. METHODS: Patients who underwent sternal median incision heart surgery from September 2014 to March 2015 were recruited. The clinical information of these patients during hospitalization was collected, and the CT scan data were submitted to the two chief physicians of the Radiology Department for radiographical sternal healing score determination. Based on the method of wound closure, the patients were divided into sternum plate (Plates) and wire groups (Wires). RESULTS: Forty-four patients were recruited. The mean CT examination time was 17.27 ± 2.30 months postoperatively. Twenty-nine (65.9%) patients met the criteria for radiographic sternal healing. Three segments, including the aortopulmonary window, the main pulmonary artery, and the aortic root, had healed less in comparison to the manubrium segment. Compared to patients in whom 6-7 metal wires were used for sternal closure, healing of the lower sternum was worse in patients in whom five wires were used, but the difference in healing was not statistically significant. Univariate analysis of sternal healing showed that patient age was a risk factor for sternal non-healing. When the patient age was > 45 years, the predicted risk of radiographic sternal non-union was 1.833 (95% CI: 1.343-2.503). CONCLUSIONS: At the mid-term follow-up, 65.9% of patients undergoing median sternotomies demonstrated radiographic sternal healing. Age, but not closure device, was a risk factor for sternal non-healing in low risk patients. Use of more wires had a positive impact on sternal healing.

Cerebral ischaemia following anterior upper thoracic spinal surgery utilizing a partial manubrial resection.

PURPOSE: Firstly, to describe two cases of cerebral ischaemia complicating anterior upper thoracic spinal surgery and define the likely cause of this complication. Secondly, to describe preventative measures and the effect these have had in reducing this complication within our institution. METHODS: Firstly, a review of two cases of cerebral ischaemia complicating anterior upper thoracic spinal surgery utilizing a partial manubrial resection. Secondly, cadaveric dissections of the carotid arteries to determine the effect of neck positioning and aortic arch retraction during a simulated procedure. Thirdly, a retrospective review of 65 consecutive cases undergoing this procedure and assessment of the rate of this complication before and after the adoption of preventative measures. RESULTS: Two cases of carotid artery territory cerebral ischaemia, without radiographic evidence of carotid or cardiac pathology were identified in 50 consecutive cases prior to the implementation of preventative measures. These patients revealed fluctuating hemodynamic instability after placement of the inferior retractor. Cadaveric dissection reveals significant carotid artery traction particularly with neck extension. Since the adoption of preventative measures, no cases of cerebral ischaemia have been encountered. CONCLUSIONS: Cerebral ischaemia is a potential complication of anterior upper thoracic spinal surgery requiring retraction of the aortic arch. This most likely occurs from carotid stenosis due to aortic retraction and therefore, may be reduced by positioning the patient with neck flexion. Continuous non-invasive monitoring of cerebral saturation, as well as actively monitoring for hemodynamic instability and reduced carotid pulsation after retractor placement, allows for early detection of this complication. If detected, perfusion can be easily restored by reducing the retraction of aortic arch.

Manubrium resection and reconstruction for mediastinal tumor: a case report.

Primary mediastinal tumours with chest wall involvement represent technical challenges that may offer a survival benefit. Reconstruction with osteossynthesis material, bioprosthesis and muscle flaps is indicated to re-establish the excised component function. We report a case of a 30-year-old male with a primary mediastinal seminoma operated after chemotherapy with need for en bloc resection of the residual mass and manubrium with chest wall reconstruction. This type of surgery is rare and represents a technical challenge. Therefore, it should be performed in referral centers and with a multidisciliplinary approach.

Tumores primários do mediastino com envolvimento da parede torácica representam desafios cirúrgicos que podem proporcionar um benefício na sobrevida. A reconstrução com material de osteossíntese, biopróteses ou retalhos musculares está indicada para restabelecer a função dos segmentos excisados. Reportamos o caso de um doente de 30 anos do sexo masculino submetido a cirurgia após quimioterapia adjuvante por seminoma primário do mediastino com necessidade de ressecção em bloco do tumor residual e manúbrio com reconstrução da parede torácica. Este tipo de cirurgia é rara e representa um desafio a nível técnico, devendo ser realizada em centros de referência e com abordagem multidisciplinar.

Custom-made Prosthesis for Reconstruction after Radical Resection for Chondrosarcoma of Manubrium.

The clinical incidence of tumors in the manubrium is not high. Regardless of whether the tumor is primary or metastatic, the tumor should be completely removed as long as the patient is able to tolerate the surgery. This procedure can lead to sternal defects. Deciding on the method of defect reconstruction is a critical problem that clinicians face. In this , to reduce the limitations of the patient's upper body movement after surgery due to the inflexibility in the connections of the sternal prosthesis, we created a prosthesis using a computer-assisted design method and a 3-D technique, to completely preserve the agility of the sternum and maximize the patient's post-operational movement. The method used in the present study takes into consideration the individual's chest anatomy, sternum stress, and many other biological characteristics. Care is taken to measure the sternum size accurately, to provide personalized treatment, to accomplish precise results, and to reduce potential future damage. The patient's shoulder function was improved following the procedure.

Expansile manubriotomy for ventral cervicothoracic junction disease.

Cervicothoracic junction can be approached anteriorly, anterolaterally, posterolaterally, and posteriorly. The anterior approaches in this region best address the ventral vertebral body disease but may cause significant morbidity. Twelve patients with their disease process located ventral to the spinal cord in the cervicothoracic junction underwent expansile manubriotomy and corpectomy. Eleven patients underwent fusion. One patient underwent an oblique corpectomy. All patients had their disease process from T1 to T3 vertebral levels. After dissection, the manubrium was cut open in the midline until the sternal notch. Further manubrial cut was extended laterally to just below the second rib. A self-retaining retractor was placed and opened. This gave an additional exposure of 10 cm from the midline towards the right side. It also opened the thoracic inlet. The superior mediastinum was dissected. Brachiocephalic vessels were looped down and a plane was made between the carotid artery laterally, and the trachea and esophagus medially. The prevertebral fascia was reached and opened to access the vertebral body. The procedure could be carried out successfully in all the patients. A patient with uncontrolled diabetes mellitus and end-stage renal disease with pyogenic epidural abscess succumbed to her illness after 3 weeks. Expansile manubriotomy is technically feasible, less invasive, and least morbid of all the anterior approaches for accessing the anteriorly located disease process above the T4 vertebral level.
