distal phalanx transphyseal fracture
The articular relations of the medial condyle and proximal ulna are not as easy to evaluate in the immature skeleton. [28] See the images below. The long finger is the most Oblique views may be required to depict these fractures, since some are not apparent on AP views. Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi. The dashed radiocapitellar line is drawn through the radial neck and should pass through the capitellum. [QxMD MEDLINE Link]. MRI coronal T2* gradient echo (B) and axial fat suppressed T2-weighted (C) images better show the extent of the fracture through the cartilaginous aspect of the medial epicondyle. The Difficult Supracondylar Humerus Fracture: Flexion-Type Injuries. DeFroda SF, Hansen H, Gil JA, Hawari AH, Cruz AI Jr. Radiographic Evaluation of Common Pediatric Elbow Injuries. The Elbow: Physeal Fractures, Apophyseal Injuries of the Distal Humerus, Osteonecrosis of the Trochlea, and T-Condylar Fractures. In searching for subtle fractures, knowing their expected location is essential. Radiography also helps identify volar fracture of the middle phalanx and other associated injuries. (A) Anteroposterior view. Alternatively, the distance from the tip of the distal phalanx to the base of the middle phalanx can be measured before needle selection. Reduction is similar to that of a dorsal PIP dislocation if no concomitant injury is present. Both direct and indirect findings are helpful in the radiographic diagnosis of supracondylar fractures. [QxMD MEDLINE Link]. It usually involves injury to the volar plate and may include a volar plate avulsion fracture. Transphyseal fracture. Displaced proximal radial fractures may result from transient posterior elbow dislocation. AJR. Salter-Harris type IV injuries will often follow typical location patterns and most commonly involve the distal radius, phalanges and distal tibia. Bookshelf Successful relocation produces immediate relief of discomfort and resolution of the deformity. [QxMD MEDLINE Link]. In most patients, the medial epicondyle is extra-articular; therefore, a joint effusion is not present. Fig.1. Demonstration of normal alignment between the proximal radius and the capitellum (radiocapitellar line) and normal alignment of the proximal radius and ulna with each other are the keys to differentiating transphyseal fracture from elbow dislocation. Other injuries that may be confused with lateral condyle fractures include supracondylar fracture, true Salter-Harris type II fracture, and, in young infants, separation of the distal humeral epiphysis (transphyseal fracture, Salter-Harris type I). Note the abnormal relation of anterior humeral line on the lateral view. The bones of the hand and wrist are shown in the figure ( figure 1 ). All of the bones in the thumb are susceptible to fracture. As with lateral condyle fractures, medial condyle fractures are often unstable and may be complicated by nonunion. Dislocations are described as dorsal, volar, or lateral depending on the direction of the middle phalanx to the proximal phalanx. As with lateral condyle fractures, these are typically Salter-Harris type IV injuries. Decompress associated subungual hematoma with 18-gauge needle placed through the nail. (B) Anteroposterior contralateral comparison. Become a Gold Supporter and see no third-party ads. Finger dislocations should be reduced as quickly as possible and concurrent soft tissue injuries treated appropriately. 2007;27:154157. The capitellum and radiocapitellar joint are best seen on the radiocapitellar view. Care must be taken to ensure a true AP view, as rotation changes the Baumann angle. Initial anteroposterior (A) and lateral (B) views show a nondisplaced lateral condyle fracture. With this in mind, the average age at which the centers are seen first in 50% of children is age 3 months for the capitellum, 5 years for the medial epicondyle, 8 years for the trochlea, and 10 years for the lateral epicondyle. By Gregory Rubin, DO rubinsportsmed.com Case Conclusion A 19-month-old male presented to the ED with an open fracture dislocation of his middle finger distal phalanx after his finger was caught inside a door hinge. Incidence of unsuspected fractures in traumatic effusions of the elbow joint. Monteggia variant. Vascular injury may be a severe complication of supracondylar fractures, usually occurring with significant posterior displacement of the distal fragment, with the brachial artery injured by the sharp distal end of the proximal fracture fragment. [9, 10, 11], A review of medical records of 462 children (median age, 6 yr) with elbow fractures identified the most common fractures as supracondylar (N=258, 56%), radial neck (N=80, 17%), and lateral condylar (N=69, 15%). Clinical features that suggest a medial condyle fracture include instability and a limitation of elbow motion. In a meta-analysis of 5154 supracondylar fractures in children, nerve injury occurred in 11%. In most cases, the fracture line then partially traverses the physis and then passes into the cartilaginous distal humeral epiphysis (see the image below). It can take 3 months or more to regain full use of the hand, depending on the severity of the injury. They found that the total cost of supplies and nonphysician labor was $432.31 per OR case and $179.59 per procedure room. Initial evaluation of vascular injury is clinical. This technique has not been previously described in the Orthopedic literature for diverse pattern of fractures of the distal phalanx. Reference article, Radiopaedia.org (Accessed on 01 May 2023) https://doi.org/10.53347/rID-41775, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":41775,"questionManager":null,"mcqUrl":"https://radiopaedia.org/articles/distal-phalanx-fracture/questions/1272?lang=us"}. [36, 37]. This humeroradial or radiocapitellar joint permits the radius to flex and extend relative to the humerus and to rotate throughout elbow flexion and extension.

(B) The lateral view shows posterior displacement and angulation of the distal fragments, appearing similar to a type III supracondylar fracture. Subsequent views (C and D) show lateral and posterior displacement of a distal fragment. A needle is selected that is of sufficient length to traverse the distal phalanx and cross the DIP joint into the middle phalanx for improved stability of the temporary fixation. The mechanisms of dislocation include a fall on an outstretched arm with the elbow partially flexed and forced hyperextension, although both mechanisms more frequently result in fractures than in dislocations. WebYou have broken your distal phalanx (the end of your finger). ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Fracture of the medial condyle is an uncommon injury in children. Supracondylar fracture. Note the normal position of the medial epicondyle in left elbow, which is not seen in the right elbow. 1992:753. Most patients with lateral condyle fractures are younger, and the epiphyseal extension of the fracture is within the growth cartilage and thus not identifiable on plain radiographs. WebAbstract. 2nd ed. Extreme tenderness when the thumb is touched, A misshapen or deformed look to the thumb, Test the tendons and nerves of the thumb to make sure there are no other associated injuries, Look for injuries to the other digits and the rest of the hand, Stress the ligaments of the thumb to make sure they are strong and have no evidence of injury. The frequency of olecranon fractures on follow-up may suggest the occult nature of these fractures. Complications of lateral condyle fracture. Obstetric traumatic separation of the distal humeral epiphysis is a rare injury that follows a traumatic delivery, often secondary to an abnormal presentation.1, 2 In a historical review of 30 years of experience, Madsen 3 documented only one case of distal humeral epiphysis separation in 105,119 neonates. These may have some angulation but no true displacement of the fracture fragment and no shift of the olecranon. With healing, sclerosis is demonstrated across the entire metaphysis, indicating the full extent of the fracture (see the image below). Treatment of phalangeal fractures. The other bones of the thumb the distal phalanx and proximal phalanx are also susceptible to fractures. 9 (1):7030. doi: 10.1007/s12306-015-0366-z. Unable to process the form. Injury and follow-up x-rays for a 19-month-old middle finger distal interphalangeal joint fracture dislocation treated with closed reduction and, Injury, postreduction, and follow-up x-rays for a small finger. [QxMD MEDLINE Link]. Metaphyseal fractures can be undetectable clinically and show only in bone survey. When the cast is removed, your doctor may recommend hand therapy to restore movement to your hand. Barton KL, Kaminsky CK, Green DW, et al. Lastly, mini c-arms are now widely available in EDs. 2015;81:296302. Pain and swelling: Take your normal painkillers if you are in pain. Salter-Harris type I fractures that pass entirely through the physis of the olecranon apophysis may occur, but they are relatively uncommon. 2017 Feb 20. The distal ulnar epiphysis is best depicted on the anteroposterior view, on which it is seen to overlap the ulnar metaphysis. (B) Lateral intraoperative image shows reduction and pinning of the fracture, which is well aligned.

Burr, MD, at [emailprotected] or by mail at Department of Orthopaedic Surgery and Rehabilitation, Loyola University Medical Center Maywood, IL 60153. A padded splint can be used to prevent the bone from moving farther out of alignment. Lateral condyle fracture with instability. Normal proximal radial metaphyseal notch. LIVIN' ON THE MD EDGE: Drive, Chip, and Putt Your Way to Osteoarthritis Relief, Osteoporosis and Osteopenia: Latest Treatment Recommendations, Osteoporosis: A Bare-Bones Guide to Diagnosis and Treatment. Typical supracondylar fracture. It is normal for your finger to be a bit achy and swollen for a couple of months after this type of injury. A radial fracture with apex anterior angulation is present. This motion causes the ulna to fracture and contact the proximal radius, forcing the radial head to become dislocated from the capitellum. These fractures usually have anterior displacement of the distal fragment. Although only a very thin sliver of bone may be viewed, it represents the small ossified portion of the entire distal fragment that is mostly cartilage (see the image below). WebFractures of distal phalanx Distal Phalanx Tuft Fracture Examination reveals local swelling and tenderness +/- deformity +/- nailbed injury Management consists mainly of treating any associated soft tissue or nailbed injury or tip avulsion. These ossification centers vary not only with regard to the age of the patient at the time of development but also with regard to their radiographic appearances. Oetgen M, Dodds S. Non-operative treatment of common finger injuries. Felix S Chew, MD, MBA, MEd Professor, Department of Radiology, University of Washington School of Medicine [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. Anteroposterior (A) and lateral (B) views show significant lateral and posterior displacement of a distal fragment. Almost most distal phalanx fractures can be treated nonsurgically with splinting, a small subset warrant internal fixation to potentially avoid adverse outcomes. The bone under the nail that makes up the tip of the thumb is called the distal phalanx. (2017) RadioGraphics. An avulsion fracture (Figure 5) typically results from forced hyperextension of a flexed DIP joint. The goals of this simple intervention are to decrease unnecessary burden on the health care system, provide better care to patients, and potentially improve outcomes for patients with this type of injury. In children, an ulnar fracture often is manifested by plastic bowing without a discrete fracture line, as shown in the image below. The smooth end of the ulna is the metaphysis ending at the physial fracture. Reduction is often successful without anesthesia. 6. The PIP joints are primarily stabilized by the matching articular phalangeal surfaces plus supportive soft tissue structures, including the collateral ligaments and volar plates. Anteroposterior (A) and lateral (B) views. Metacarpal fractures are seen more often in adults, whereas phalangeal fractures are more common in children [ 2 ]. Such complications include nonunion or fibrous union. This relation should be examined on a frontal view as well. WebThe majority of fractures of the distal phalangeal diaphysis are closed and either undisplaced, or minimally displaced. Surgical management is most commonly performed with the aid of an arthrogram. Copyright 1995-2021 by the American Academy of Orthopaedic Surgeons. Failure to identify and appropriately treat these fractures can lead to long-term reduced function and disability. Orthop Rev (Pavia). Flexion injury is often from a fall on a flexed elbow, whereas extension injury is often from a fall on a slightly flexed and outstretched arm, with the coronoid process acting as the wedge. The thumb also has several nerves that give you feeling and blood vessels that provide the thumb with blood flow. For those injuries that include a small portion of the metaphysis, care must be taken to distinguish medial epicondyle fracture (usually an extraarticular injury) from medial condyle fracture, which extends to the articular surface. Anteroposterior (A) and lateral (B) views of the injured right elbow compared with anteroposterior (C) and lateral (D) views of the uninjured left elbow. Fredric A Hoffer, MD, FSIR is a member of the following medical societies: Children's Oncology Group, Radiological Society of North America, Society for Pediatric Radiology, Society of Interventional RadiologyDisclosure: Nothing to disclose. Anteroposterior view shows an obvious lateral condyle fracture with lateral displacement of the fragment, rotation, and downward displacement caused by muscular traction. Simplistically, a Monteggia fracture/dislocation may be thought of as the result of a force that dislocates the radial head and simultaneously fractures the ulna in the same direction. [33] For extension fractures, the anterior interosseous branch of the median nerve is most frequently injured, whereas with the rare flexion type supracondylar fractures, the ulnar nerve is most often involved. The assessment should also include finger alignment, ligament integrity, neurovascular status, and flexion and extension of the joints. Depending on the particular injury pattern, a closed reduction is performed of the distal phalanx fracture and/or distal interphalangeal (DIP) joint dislocation. Medially, the trochlear notch articulates with a corresponding ridge along the ulna. Features that help in distinguishing between transphyseal and lateral condyle fractures include alignment of the radiocapitellar joint and the direction of displacement. [QxMD MEDLINE Link]. 4. Arthritis can result in limited joint motion and pain in the joint. Follow-up anteroposterior (C) and lateral (D) views demonstrate the fracture better. For the normal elbow (B), note the normal position of the medial epicondyle along the medial aspect of the distal humeral metaphysis. 88(5):980-5. The Milch classification scheme for lateral condylar fractures defines a type I fracture as one that passes through the distal humeral epiphysis lateral to the lateral crista of the trochlea, in most cases passing through the ossified capitellum. david and patricia carlin, sa12 recone kit,
