BACKGROUNDRIB FRACTURESRib fractures are common in blunt chest wall trauma.The fractured ribs usually heal on their own without specific treatment, but a subset of patients have fractures that produce overlaying bone fragments that mayproduce severe pain, respiratory compromise, and chestwall deformity.Most of the fractured ribs are treated with conservativenon-operative care. These include aggressive pain mana gement (epidural analgesia, rib oral analgesics and/orbracing techniques), and ventilation and tracheotomy1until fibrous stabilization is achieved. These treatmentmethods have been shown to have good results in respect to restoration of the damaged chest wall, but havehigher chest infection and mortality rates compared tosurgical treatment.2More severe chest wall trauma is a major cause of morbidity and mortality, especially in the presence of a flailchest where paradoxical inward movement of the flailsegment in inspiration is found. Patients with flail chestoften require aggressive pain control, ventilation, andprolonged ICU stay.1About 10% of chest wall trauma cases result in a flailchest.4 Flail chest injuries, defined as fracture of at leastthree consecutive ribs in at least two locations each, areassociated with a mortality rate of up to 36%.3, 4 Flailchest injuries develop paradoxical inward movement ofthe flail segment which prevents effective inspirationand require prolonged mechanical ventilation which canlead to pneumonia and sepsis.32DePuy Synthes MatrixRIB Surgical TechniqueImage courtesy of Mario G. Gasparri, MD at MedicalCollege of Wisconsin, USA

The need to improve rib fracture treatment has beenreco gnized for many years and some surgeons havebeen using operative approaches including plates, intramedullary devices, vertical bridging, wire, sutures, andstruts to repair the chest wall.2, 3, 4, 5, 6, 7, 8, 9These attempts indicate a trend in better rib fracturetreatment to improve pain control, reduce duration of mechanical ventilation, reduce ICU stays, reduce the risk forchest wall deformities and ultimately improve patient care.MatrixRIB Surgical TechniqueDePuy Synthes3

BackgroundCHEST WALL DEFORMITYPectus Excavatum is the most common congenital chestwall deformity where the sternum is depressed. Anotherless common deformity of the sternum, known as PectusCarinatum, is where the sternum protrudes.Almost all patients with severe Pectus excavatum indicate that they have progressive symptoms of early fatigability, dyspnea, decreased endurance, tachycardia andtachypnea with physical exertion. With moderate-to-severe Pectus excavatum, the heart is often displaced intothe left chest and compressed, causing reduced strokevolume and cardiac output during exertion. Pulmonaryexpansion during inspiration is moderately confined, resulting in restriction, which often is noted on exercisepulmonary function tests. Physiologic impairment andreduced exercise capacity may be attributable to impaired cardiovascular performance rather than ventilatorlimitation.10Pectus excavatum repair has demonstrated significantimprovement in maximum voluntary ventilation, maximum oxygen utilization, and total lung capacity measured during exercise. Pectus excavatum repair that includes internal sternal support has been shown tominimize the occurrence of postoperative respiratory distress caused by paradoxical chest motion, to reducepain, to permit early ambulation and permit deeper respirations, and to maximize the extent to which thedefect is permanently corrected.10During most open surgical procedures, small sections ofdeformed costochondral cartilage are removed to freethe sternum laterally. A transverse wedge osteotomy isoften made in the sternum at the onset of the deformityto enable repositioning of the sternum into the correctanatomic position. Once approximated, the sternummust be fixated in place for the duration of the bonehealing process. Depending on the surgeon, fixation canoccur along the transverse sternotomy and/or laterallyfrom rib-to-rib along the sternum.4DePuy Synthes MatrixRIB Surgical Technique

CHEST WALL RESECTIONLarge resections of the chest wall, including the ribs, sternum, and/or surrounding soft tissue, are performed forthe curative and palliative treatment of malignant and benign tumors, radiation necrosis, and deep sternal woundinfections. Resections of defects greater than 5 cm in dia meter require skeletal reconstruction to maintain physiologic respiratory function and protect vital intrathoracicorgans.11 Paradoxical respiration may occur withoutproper stabilization causing pain, respiratory distress, andoften necessitating long term mechanical ventilation. Themain goals of reconstruction are: prevention of flail chest,maintenance of physiologic respiration, protection of thoracic organs, and an acceptable cosmetic result.11MatrixRIB Surgical TechniqueDePuy Synthes5

MRI INFORMATIONTorque, Displacement and Image Artifactsaccording to ASTM F 2213-06, ASTM F 2052-14 andASTM F2119-07Non-clinical testing of worst case scenario in a 3 T MRIsystem did not reveal any relevant torque or displacement of the construct for an experimentally measuredlocal spatial gradient of the magnetic field of 5.4 T/m.The largest image artifact extended approximately 35 mmfrom the construct when scanned using the GradientEcho (GE). Testing was conducted on a single SiemensPrisma 3 T MRI system.Radio-Frequency-(RF-)induced heating accordingto ASTM F2182-11aNon-clinical electromagnetic and thermal simulations ofworst case scenario lead to temperature rises of 21.7 C(1.5 T) and 12.4 C (3 T) under MRI conditions using RFCoils (whole body averaged specific absorption rate(SAR) of 2 W/kg for 15 minutes).Precautions: The above mentioned test relies onnon-clinical testing. The actual temperature rise inthe patient will depend on a variety of factors beyond the SAR and time of RF application. Thus, it isrecommended to pay particular attention to the following points: It is recommended to thoroughly monitor patientsundergoing MRI scanning for perceived temperature and/or pain sensations. Patients with impaired thermo regulation or temperature sensation should be excluded from MRIscanning procedures. Generally it is recommended to use an MRI systemwith low field strength in the presence of conductive implants. The employed specific absorptionrate (SAR) should be reduced as far as possible. Using the ventilation system may further contribute to reduce temperature increase in the body.6DePuy Synthes MatrixRIB Surgical Technique

Intended use, Indications, Contraindicationsand WarningsImportant: The Synthes MatrixRIB pre-contouredand straight plates are not indicated for use aspermanent implants for bridging gaps after chestwall resections.ContraindicationsThe MatrixRIB Fixation System is contraindicated for: The fixation of the sternum in acute cardiacpatients, due to the potential delay if emergentre-entry is required Screw attachment or fixation to the clavicle or spine Use in patients with latent or active infection,with sepsis, or who are unwilling or incapable offollowing postoperative care instructions.Warnings Metallic internal fixation devices cannot withstandactivity levels and/or loads equal to those placed onnormal healthy bone as these devices are not designedto withstand the unsupported stress of full weightbearing, load-bearing, or gap spanning which mayresult in fatigue failure of the device. Additionally, using the device for spanning gaps inpatients that put extreme strain on the implant (e.g.overweight or non-compliant) may further contributeto premature device failure. These devices can break intraoperatively whensubjected to excessive forces or outside the recommended surgical technique. While the surgeon mustmake the final decision on removal of the broken partbased on associated risk in doing so, we recommendthat whenever possible and practical for the individualpatient, the broken part should be removed. Medical devices containing stainless steel may elicit anallergic reaction in patients with hypersensitivity tonickel.8DePuy Synthes MatrixRIB Surgical Technique
