Adams, MD, Middle Atlantic Shoulder & Elbow Society Annual Meeting 2021, Panel: "There is a fracture, I must fix it" - Clavicle, AC, SC Joint Injuries; Let's Goooo! Fracture at the base of the 5th metatarsal tubercle. The second and third metatarsals receive the majority of stress during ambulation and are less mobile compared with the other metatarsals. They include, primary stabilizer of atlantoaxial junction, prevents posterior migration of the odontoid into the spinal canal, connects the posterior odontoid to the anterior atlas arch, inserting laterally on bony tubercles of the lateral mass, connect the odontoid to the occipital condyles, relatively strong and contributes to occipitalcervical stability, connects the posterior body of the axis to the anterior foramen magnum and is the cephalad continuation of the PLL, occipital condyles articulate with C1 superior articular processes, provides ~50% of cervical spine flexion and extension range of motion, contains anterior and posterior joint capsules, articulation between the inferior facet of C1 and superior facet of C2, aticulation between the dens (C2) and the anterior arch of the atlas. What is the most appropriate initial management of the patient's injuries in . A radiograph taken at the time of injury is shown in Figure A, and a current radiograph is shown in Figure B. > 50-75% destruction of metaphysis (> 2.5 cm) Permeative destruction of the subtrochanteric femoral region. Atlas Fractures & Transverse Ligament Injuries are traumatic injuries usually caused by high-energy trauma with axial loading in young patients (Jefferson Fracture) or low-energy falls in elderly. Stable injuries can be treated with immobilization in a cervical collar. Treatment is nonoperative or operative based on patient activity and demands, along with degree of displacement, shortening, and comminution. Open reduction and intramedullary nailing. ranges between 1.8% to 27% depending on the bone involved and grade/fracture type. Traditionally, children aged 4 - 11 years are less likely than adolescents and adults to suffer a scaphoid fracture. The most common mechanism that cuts this ligament is foot eversion or external rotation force. What is the optimal treatment for the proximal phalanx fracture shown in Figure A? the tibia is the most common site of post-surgical osteomyelitis following surgical treatment of open fractures, delay in defintive soft tissue coverage greater than 7 days. Radiographic features Plain radiograph Small curvilinear fragment close to the medial femoral condyle at the origin of the medial collateral ligament. Stability determined by the integrity of the transverse ligament. 164 plays . The risk of infection from these types of wounds can vary depending on the type and pattern of bullets fired as well as the distance from the firearm. Decreased chance of nonunion with nonoperative treatment, Improved Constant and DASH scores with operative treatment at all time points, Increased symptomatic malunion rate with operative treatment, Increased time to union with operative treatment. Bimalleolar ankle fracture is caused by twistingwith multiple force mechanisms, or supination injury. clavicle fractures account for 2.6-4% of all adult fractures, 75-80% of all clavicle fractures will occur in the, fall onto lateral aspect of shoulder (85%), junction of the outer and middle third is the thinnest part of the bone, posterosuperiorly by sternocleidomastoid muscle, inferomedially by pectoralis major and and weight of arm, open fractures usually result from medial fragment "buttonholing" through platysma, ipsilateral scapular fracture (floating shoulder), significantly distracted/widened fracture fragments, widened interval between scapula and spine, flat laterally, tubular centrally, and prismatic medially, provide superior/inferior stability to AC joint, clavicular head originates superiorly on medial third, stabilizes distal clavicle and assists with shoulder abduction, shortening of clavicle decreases lever arm of deltoid, originates from anterior lateral third clavicle, acromion, and scapular spine, originates from occiput and C-T spine spinous process, inserts on lateral posterosuperior third of clavicle, acromion, and scapular spine, clavicular head originates from anteroinferior surface of medial half of clavicle, inserts on crest of greater tubercle of humerus, lateral to bicipital groove, protects NV structures which pass deep to muscle and displace clavicle inferiorly, originates from 1st rib and costal cartilage, cutaneous nerves that run vertically over clavicle and supply superior chest wall, passes posterior and underneath clavicle near junction of medial and middle third, subclavian vein closest to clavicle and anterior to artery and plexus, middle third is weakest portion of clavicle, transitional of the bone in both curvature and in cross-sectional anatomy, only area not supported by ligamentous or muscular attachments, popping or cracking sound near shoulder after fall, acute onset of anterior shoulder pain or directly over clavicle, tender, swelling, crepitus and deformity over clavicle, assess subclavian vessels and brachial plexus, supine may underappeciate displacement with gravity eliminated, evaluate for other injuries (ie proximal humerus, scapula), compare shortening with contralateral side, inferior displacement of lateral fragment, AP clavicle - distance between the corresponding ends of the medial and lateral fragments, AP chest - direct comparison of length of clavicle to the contralateral side, shortening >2cm associated with decrease shoulder strength and endurance, displacement relative to width of clavicle (percent), >100% displacement is a risk factor for nonunion, assess fracture pattern for preop planning, comminution, shortening, articular extension, nonunion, axial, coronal and 3D reconstruction most useful, with contrast if concern for vascular injury, may present with dysphagia, stridor, asymmetric pulses, paresthesias due to compression of surrounding structures, serendipity view or CT best demonstrate displacement, pain and prominence more lateral over AC joint, zanca or axillary views shows displaced distal clavicle relative to acromion, < 1cm displacement of the superior shoulder suspensory complex, elevate and extend shoulder to bring distal fragment to the proximal fragment, figure-of-8 associated with more pain, shortening, and lower compliance than sling, no difference in functional or cosmetic outcomes between sling and figure-of-eight braces, floating shoulder (clavicle and scapular neck fracture), brachial plexus injury (questionable because 66% have spontaneous return), open reduction internal fixation with plate and screws, operative fixation has higher union rate (>94%), similar or better functional outcomes than nonoperative, immobilize using sling or figure-of-eight brace, higher nonunion rate compared to operative management, decreased shoulder strength and endurance, displaced midshaft clavicle fractures healed with > 2cm of shortening, increased plate strength with inferior bone comminution, low rate of symptomatic hardware removal (0-3.7%), biomechanically equivalent or superior to single 3.5mm plate, limited contact, pre-controured, 3.5mm dynamic compression plate, 2.0mm, 2.4mm and 2.7mm plates can be used and combined for dual plating, improved results with ORIF for clavicle fractures with > 2cm shortening and > 100% displacement, improved functional outcomes/less pain with overhead activity, decreased symptomatic nonunion and malunion rate, increased shoulder strength and endurance, increased risk of need for future procedures, sling for 7-10 days followed by active motion, strengthening at ~6 weeks when pain-free motion and radiographic evidence of union, full activity including sports at ~3 months, goal size of intramedullary nail is 30-40% of midshaft diameter, avoids supraclavicular nerves that are commonly injured with plating, hardware migration, implant irritation, secondary procedures, typically requires hardware removal at 6 months, motion at fracture site, no callus on x-ray, DASH <40, pain and increased fatigue with overhead activities, difficulty with shoulder straps and backpacks, clavicle osteotomy with bone grafting, if symptomatic, superior plates associated with increased irritation, superior plates associated with increased risk of subclavian artery or vein penetration, 83% incidence of numbness noted at 2 weeks postop, can improve over time with ~50% having persistent numbness at 1 year, 4% in surgical group develop adhesive capsulitis requiring surgical intervention, Open treatment of clavicular fracture, includes internal fixation, when performed, Adult Knee Trauma Radiographic Evaluation, Proximal Humerus Fracture Nonunion and Malunion, Distal Radial Ulnar Joint (DRUJ) Injuries. Which of the following factors is not a risk factor to the development of this patients diagnosis? The Cyma line can also be disrupted 4 A pelvic ring fracture is a severe fracture with 2 breaks in the circular ring, leading to an unstable pelvis and a potentially unstable patient. (OBQ09.138) A 33-year-old male sustains a distal humerus fracture and is treated with open reduction and internal fixation of the distal humerus with olecranon osteotomy. Which of the following has been shown to be true regarding operative versus nonoperative treatment of this injury? Open reduction and internal fixation with plating, Closed reduction and percutaneous pinning, Nonoperative treatment with a sling and early range of motion. The patient is interested in pursuing surgical intervention. (OBQ11.118) (SBQ12TR.23) Epidemiology Associations 50% are associated with other C-spine injuries 33% are associated with a C2 fracture 25-50% of young children have a concurrent head injury Of the following possible complications from nonoperative treatment, which is the most likely? This type of fracture often affects these ligaments. Diagnosis can be confirmed with orthogonal radiographs of the involve digit. Willis AA, Kutsumi K, Zobitz ME, Cooney WP 3rd.
