Metacarpal fractures are seen more often in adults, whereas phalangeal fractures are more common in children [ 2 ]. [QxMD MEDLINE Link]. Initially this leaves a wide space between the lateral epicondyle ossification center, which typically has a linear pattern, and the lateral condyle, which can be misinterpreted as an avulsion fracture. If an associated radial fracture is not identified, a careful search should be made for a radiocapitellar dislocation or subluxation. Philadelphia:. The distal ulnar epiphysis is best depicted on the anteroposterior view, on which it is seen to overlap the ulnar metaphysis. Rotator Cuff and Shoulder Conditioning Program. A 5-year-old child with type III supracondylar fracture and brachial artery injury. [41] See the image below. Fat pad signs indicate an elbow joint effusion. Distal phalanx, distal and shaft, transverse - AO Foundation Rabiner JE, Khine H, Avner JR, Friedman LM, Tsung JW. J Bone Joint Surg. Some institutions attempt to circumvent these challenges by running a dedicated procedure room within the emergency room (ER) for these procedures. This rotation allows for supination and pronation of the forearm and depends on proper motion of the proximal radioulnar joint (the third articulation of the elbow) and on the normal mobility of the forearm and wrist. Transverse fractures are common in both accidental and non-accidental traumas. The rare Salter-Harris type II may mimic lateral condyle fracture radiographically, but not clinically. In transphyseal fracture, the distal humeral epiphysis and forearm bones are usually displaced medially, whereas in true elbow dislocations, the radius and ulna are dislocated either laterally and posteriorly (in children >2 y) or primarily posteriorly (in children < 2 y). [9, 5, 20, 21, 22, 23, 24, 25, 26, 1], Supracondylar fractures are the most common elbow fracture in children, accounting for 50-60% of all elbow fractures. 65 (10): 773-80. 4:592-607. Web[2,3]. If the bones remain in a stable position with good alignment, thumb fractures generally heal well. Some transphyseal fractures include a small portion of the metaphysis as shown in the image below; such a finding is helpful in recognizing that a fracture is present. 5. A notchlike defect in the proximal radial metaphysis may be confused with a fracture (see the image below). If there is instability or significant rotation, referral to a hand surgeon is required. Once the fracture has healed, it is very important to follow all therapy instructions to improve motion in the thumb. Differential diagnosis for corner At her last follow-up 7 months postinjury, she demonstrated radiographic healing of her fracture and returned to full work with only mild limitations in strength and range of motion. Fractures at the base of the distal phalanx are often unstable due to the fact these are the insertions sites for both the flexor and extensor tendon, however splinting of these fractures, granted they are closed has favorable outcomes 3. With medial displacement or medial comminution, loss of support for the medial aspect of the distal fragment allows the distal fragment to shift into varus alignment. A variety of 18- and 20-G short hypodermic needles are available in all practice settings. For the normal elbow (B), note the normal position of the medial epicondyle along the medial aspect of the distal humeral metaphysis. Almost most distal phalanx fractures can be treated nonsurgically with splinting, a small subset warrant internal fixation to potentially avoid adverse outcomes. 2016 Apr. Since relatively little growth occurs at the distal humerus, angular deformity in most cases is not due to growth disturbance, but rather malunion of varus deformity. National Library of Medicine The overall sensitivity of elbow US was 88%. [QxMD MEDLINE Link]. 474 (11): 2531-2537. In these cases, only the radial head is still in alignment with the capitellum. This is sometimes called a tuft fracture Healing: This normally takes approximately 4-6 weeks to heal. Intra-articular fractures are often complicated and unstable and should be referred to a hand specialist.3 Extra-articular fractures may be nondisplaced or displaced. [22]. Abzug JM, O'TYoole RV, Paryavi E, Sterling R. Are orthopaedic residents competent at performing basic nonoperative procedures in an unsupervised setting? Once the needle has been inserted into the skin and through the distal cortex, the needle can be advanced by twisting the hub of the needle with a gentle axially directed force. Prognostic Level III. [34] Although this has not been shown in several other series, including prospective studies, in most cases supracondylar fractures are now treated with only lateral pins to avoid nerve injury. Metaphyseal fractures [corner fracture]: Commonly affects the distal femur or the proximal tibia (Fig. 2016 Jun. [QxMD MEDLINE Link]. Saeed W, Waseem M. Fracture, Elbow. Acta Orthop. [QxMD MEDLINE Link]. Supracondylar Fractures of the Distal Humerus. Kuhn MA, Ross G. Acute elbow dislocations. 39(2):163-71, v. [QxMD MEDLINE Link]. In young children in whom the distal humeral epiphysis is not yet ossified, this malalignment of the forearm bones and the distal humeral metaphysis may be mistaken to indicate an elbow dislocation. 3rd ed. Although it is important to differentiate medial condyle fractures from medial epicondyle fractures, the distinction is not always easy to make with radiographs. In evaluating the proximal ulna in children, the normal olecranon apophysis must not be mistaken for a fracture fragment. A dorsal PIP dislocation often leads to obvious dorsal deformity of the middle phalanx and volar plate tenderness. Several bones contribute to thumb function. Distal A local joint block can be considered if significant pain impedes reduction. The lucent cleft in the fracture fragment is the normal olecranon growth plate. WebDisplaced phalangeal neck fractures may be missed because the fracture may be confused with a distal physis, a minor avulsion fracture, or even a nondisplaced fracture if adequate lateral and oblique films are not obtained. [46] Some proximal radial fractures may result in abnormal articulation of the radial head and capitellum and therefore are fracture/dislocations. Yoong P, Goodwin RW, Chojnowski A. Phalangeal fractures of the hand. The presence of a metaphyseal flake fracture is not specific because some medial epicondyle avulsions extend into the metaphysis as a Salter-Harris type II fracture. Curr Rev Musculoskelet Med. Shukla M, Keller R, Marshall N, Ahmed H, Scher C, Moutzouros VB, et al. If the fracture extends into the joint, it is called an intra-articular fracture; if it does not, it is called an extra-articular fracture. It occurs due to injury or weakened bones. However, caution should be taken where there is partial overlap of the capitellum with the metaphysis. Fractures with significant radiological comminution and/or extensive soft tissue injury should be clinically and radiologically reviewed for open fracture. Orthop Clin North Am. [13] In astudy of 900 young baseball players (aged 7-11 yr), 35.2% reported episodes of elbow pain. J Trauma. eCollection 2021. Is Bone Mineral Density Testing Underused in Prostate Cancer Care? Treatment is generally straightforward, with excellent outcomes. We describe 2 patients treated with this technique at our institution: 1 child with an open fracture dislocation of the distal phalanx and 1 adult with an open transverse fracture of the distal phalanx. Hand Clin. For these fractures, the lateral crista of the trochlea is intact, maintaining stability of the elbow joint. Distal phalanx fractures are among the most common fractures in the hand. FOIA Owing to traction from the forearm flexors, the medial epicondyle is displaced distally, and usually medially, from its anatomic position (see the image below). Lateral view in a patient with osteogenesis imperfecta who has had bilateral recurrent fractures in the same region. WebTransphyseal Fracture of the Distal Humerus. WebPhalangeal fractures are the most common foot fracture in children. 1998. 6. Other causes of transphyseal fractures of the distal humerus include nonaccidental trauma and fall from a low level height [4-7]. In addition to the major distal fragments, small comminuted fragments are noted proximally. Although the radiologic diagnosis of lateral condyle fracture depends on plain radiographic findings, MRI, arthrography, or ultrasonography (US) may be useful in the further evaluation of the fractures, particularly with regard to the course of the fracture through the cartilaginous epiphysis, as shown below. The fracture is almost always about 1 inch from the end of the bone. Radiography must be performed following splint application to confirm congruity of the fracture fragment with the distal phalanx in the joint space.3 Studies show no difference in outcomes among splint types as long as DIP extension is maintained.1315. Supracondylar fracture. (A) Note the avulsion of the medial epicondyle, which projects just distal to the trochlea on the anteroposterior view. The addition of arthrography is helpful, especially for detecting intra-articular bodies. A staging system for displacement of lateral condyle fractures is as follows 2013 Jan. 61(1):9-17. Radiology of Skeletal Trauma. 533-93. [QxMD MEDLINE Link]. The next bone is called the proximal phalanx. The assessment should also include finger alignment, ligament integrity, neurovascular status, and flexion and extension of the joints. Injury, postreduction, and follow-up x-rays are shown in Figure 3. WebThe majority of fractures of the distal phalangeal diaphysis are closed and either undisplaced, or minimally displaced. Oman Med J. However, the adjacency of fracture margins for the metaphysis and capitellum poses the risk of focal physial closure. K-wire CT may be helpful to further assess the nature of the fracture. Phalangeal Fractures Treatment & Management: Fractures of the An official website of the United States government. DaCruz DJ, Slade RJ, Malone W. Fractures of the distal phalanges. Imaging Pitfalls of the Acutely Traumatized Pediatric Elbow. Become a Gold Supporter and see no third-party ads. Loss of thumb function due to a fracture can affect your ability to grasp items, and certain types of thumb fractures can increase the risk of arthritis later in life. Anteroposterior (A) and lateral (B) views show combined fractures of the distal humeral lateral condyle and olecranon process of the ulna. Distraction may also result from the ulnar collateral ligament with elbow dislocation or subluxation, which accounts for approximately half of medial epicondyle fractures in children. For more information, please refer to our Privacy Policy. 2008;1:97102. It is also referred to as the terminal phalanx. 64B:256. Unable to process the form. Thumb Fractures - Emergency Department Rang M. Children's Fractures. Transphyseal Distal Humeral Fractures: A 13-Times-Greater Risk of Non-Accidental Trauma Compared with Supracondylar Humeral Fractures in Children Less Than 3 Years of Age Prognostic Level III. [QxMD MEDLINE Link]. It is important that such entrapment be recognized; the diagnosis may be made on the basis of radiographic findings. Case Report: Locking Plate for Cubitus Varus Correction in a 7-Year-Old Girl With Osteogenesis Imperfecta. WebAbstract. [45] It has also been suggested that extension force in infants may be more likely to cause a transphyseal fracture than supracondylar fracture. Salter-Harris type IV fracture | Radiology Reference Article Philadelphia, PA: JB Lippincott; 1983. Fractures of the distal humerus include supracondylar fracture, lateral condyle fracture, medial epicondyle fracture, medial condyle fracture, and transphyseal (transcondylar fracture), and T-condylar fracture. ("Articular" means "joint.") People with a history of bone disease or calcium deficiency are especially at risk for thumb fractures. Our proposed technique would not deviate from that standard protocol. MRI, US, or arthrography may be used to directly depict the relationship of the cartilaginous distal humeral epiphysis to the metaphysis (see the image below). Fracture 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. PMC A variety of treatment modalities exist for distal phalanx fractures See the image below. The Elbow: Physeal Fractures, Apophyseal Injuries of the Distal Humerus, Osteonecrosis of the Trochlea, and T-Condylar Fractures. Nerve injuries may complicate supracondylar fractures. 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"}. Transphyseal fracture. It is normal for your finger to be a bit achy and swollen for a couple of months after this type of injury. Before This technique has not been previously described in the Orthopedic literature for diverse pattern of fractures of the distal phalanx. However, widening of the joint space may be difficult to evaluate in patients in whom the elbow is immature; in such cases, the largely cartilaginous trochlea makes the normal gap between the distal humerus and ulna appear quite wide. Postreduction radiography can be used to assess alignment. Prevention and treatment of non-union of slightly displaced fractures of the lateral humeral condyle in children. In patients younger than 2 years, elbow dislocations are exceedingly rare, and transphyseal fractures (distal humeral epiphyseal separation) are often mistaken for elbow dislocation. Unable to process the form. The authors typically use needles that are 1 or 1.5 inches in length. At the time the article was created Tom O'Graphy had no recorded disclosures. Finnbogason T, Karlsson G, Lindberg L, Mortensson W. Nondisplaced and minimally displaced fractures of the lateral humeral condyle in children: a prospective radiographic investigation of fracture stability. Medial epicondyle fracture with entrapment in an 8-year-old boy. Transphyseal fractures of the distal humerus typically occur in children younger than 3 years secondary to birth trauma, nonaccidental trauma, or a fall from a small height. A 13-year-old youth with nonunion of lateral condyle fracture and subsequent ulnar neuropathy. J Bone Joint Surg Am. In a Monteggia fracture type 3, the radial head is dislocated, primarily laterally and slightly anteriorly. J Orthop Trauma. Finger dislocations should be reduced as quickly as possible and concurrent soft tissue injuries treated appropriately. The medial and lateral columns are more separated proximally than distally. [1, 2, 3, 4] The evaluation of pediatric elbow radiographs in the setting of acute trauma may be challenging for many emergency department physicians, orthopedic surgeons, and radiologists. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Classifications In Brief: Salter-Harris Classification of Pediatric Physeal Fractures. Supracondylar fracture. Distal Phalanx The elbow is composed of 3 articulations. Radiology. Fractures of the coronoid process are infrequent in children, but they may be seen with posterior elbow dislocation. [38, 1, 39]. 7. van Leeuwen WF, van Hoorn BT, Chen N, et al. [48]. ("Articular" means "joint.") Place in stack splint for protection and pain control for 3 to 4 weeks. This website also contains material copyrighted by third parties. Oblique views may be required to depict these fractures, since some are not apparent on AP views. Treatment following simple reduction is also similar to that following PIP dislocation. Anteroposterior view shows an obvious lateral condyle fracture with lateral displacement of the fragment, rotation, and downward displacement caused by muscular traction. Although posteriorly displaced lateral condyle fractures may show an abnormal relationship between the anterior humeral line and the capitellum, this finding is not as useful in lateral condyle fractures as in supracondylar fractures. Vertically oriented fracture begins along the medial aspect of the distal humeral metaphysis and extends to the growth plate. [16], Tokarski et al found that use of conventional radiography may be reduced in patients with a low clinical concern for fracture and normal elbow ultrasound. 2008 Feb. 24(1):139-52. The 2 major complications of supracondylar fractures in children are cubitus varus (see images below), which is relatively common, and vascular injury, which is uncommon but has considerable morbidity when present. In the radiographic evaluation of pediatric elbow trauma, it is important to assess the status of the medial epicondyle, particularly after an elbow dislocation. A study by Garon et al1 assessed the cost of performing percutaneous fixation of hand fractures in a procedure room versus an OR. In most cases, lateral condyle fractures are distraction injuries from the forearm extensors, usually as a result of acute varus stress applied to an extended elbow. WebTransphyseal distal humerus fractures typically occur in children younger than 3 years secondary to birth trauma, nonaccidental trauma, or a fall from a small height. We introduce a technique to stabilize diverse fractures of the distal phalanx in the emergency department (ED) utilizing a hypodermic 18- or 20-G needle. 2018;13:428434. Broken Wedge JH, Robertson DE. Splinting for two to four weeks should be followed by range of motion and strengthening of the DIP joint. Orthop Rev (Pavia). At the time the article was created Chris Rothe had no recorded disclosures. Prompt and accurate diagnosis of a transphyseal distal humerus fracture is crucial for a [20, 27, 1]. In fact, Monteggia variant and pseudo-Galeazzi injuries are forearm fractures involving both bones, with 1 of the fractures occurring so close to the joint that a dislocation is erroneously suggested. Transphyseal Distal The peak age of occurrence for these fractures is 4-10 years. Distinguishing between these fractures is important because lateral condyle fractures are often unstable and require operative fixation, which is frequently not necessary for transcondylar fractures, which are more stable following reduction. Successful management is dependent on an early and accurate diagnosis of the injury, through clinical and radiologic evaluation. 2. Therefore, if the medial epicondyle is not seen in its expected location and a single ossicle is seen beneath the medial aspect of the distal humeral metaphysis, the ossicle should be interpreted as an avulsed medial epicondyle that is entrapped in the joint rather than a normal trochlea. 398-9. Beaty JH, Kasser JR. Rockwood and Wilkins' Fractures in Children. Reliability of a modified Gartland classification of supracondylar humerus fractures. This is sometimes called a tuft fracture Healing: This normally takes approximately 4-6 weeks to heal. Copyright 2012 by the American Academy of Family Physicians. These fractures are 1964. In the lateral projection, the fracture is often transverse, but may be oblique, extending proximally from anterior to posterior. Edmonds EW. The elbow is the most frequently dislocated joint in children, whereas in adults, dislocations of the shoulder and interphalangeal joints of the fingers are more common. On the lateral view, cortical disruption is usually seen posteriorly rather than anteriorly as in supracondylar fractures. With such bending, the joint capsule applies a tension force to the anterior cortex of the distal humerus, accounting for the frequent anterior position of the lucent fracture line. Transphyseal fracture. A major complication of a radial neck fracture is limitation of motion at the proximal radioulnar joint, which mostly limits supination. 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. The distal interphalangeal joints are formed by the articulations between the heads of the middle phalanges and the bases of the distal phalanges. Skeletal Radiol. On the frontal view, supracondylar fractures typically extend transversely through the metaphysis across the region of the olecranon fossa. Subtle olecranon fracture. Approximately 10-12% of all physeal fractures will be a Salter-Harris type IV fracture. This is particularly helpful in the distal tibia when the plain film can under-estimate the complexity and severity of a distal tibial injury. 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). Often, the capitellum has ossified; in such cases, it may serve as an important marker in the otherwise cartilaginous distal humeral epiphysis. Copyright 2023 American Academy of Family Physicians. When associated with a crush injury, open fracture is more likely. It also aids recognition of an injury when the pattern is altered. The presence of a joint effusion does not specifically indicate that a fracture is present, but a joint effusion does signal that a fracture is likely; in such cases, a careful search is required. Fracture, traumatic When the elbow is fully extended, the olecranon becomes locked into the olecranon fossa, making it susceptible to fracture by varus or valgus stress. WebYou have broken your distal phalanx (the end of your finger). {"url":"/signup-modal-props.json?lang=us"}, Rothe C, Hacking C, Jones J, et al. 50:95. sharing sensitive information, make sure youre on a federal You may inquire whether the author(s) will agree to phone conferences and/or visits regarding these techniques. Therefore, elbow radiographic findings are normal in a pulled elbow. If separation is significant, as shown below, recognition of the fracture is easy, although distinguishing these fractures from supracondylar fractures depends on knowing the characteristic course (see the image below). Injury to soft tissue can also lead to hyperesthesia, cold sensitivity, and nail abnormalities.4 Fixation with previously described techniques, most frequently CRPP with k-wires, involves overutilization of hospital resources by requiring the procedure be done in an operative room. Salter Harris Fractures. The radiographic depiction of lateral condyle fractures depends on the degree of separation at the fracture site. These broken bone fragments must be held in place while the bone heals. 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. [QxMD MEDLINE Link]. 65:371-8. Displacement of the radial head may be marked, usually with the head displaced distally, and its articular surface may be rotated into the coronal plane posteriorly. Normal radial tuberosity. Common complications of these injuries are: altered sensitivity (numbness, hyperesthesia, tenderness) cold sensitivity (cold intolerance) restriction of DIP joint movement 88(5):980-5. 83-A(5):735-40. See the Medscape Reference article Salter-Harris Fracture Imaging for more information. (A) Anteroposterior view shows a varus deformity of the distal humerus from a prior supracondylar fracture that has fully healed. 1988;13:350352. These hinge joints allow flexion and extension and are reinforced by plantar ligaments, as well as by medial and lateral collateral ligaments. J Bone Joint Surg Br. Salter-Harris type IV injuries will often follow typical location patterns and most commonly involve the distal radius, phalanges and distal tibia. The detection of these fractures requires a high index of suspicion and comparison with the noninjured elbow. Because of the risk of tendon retraction and the need for surgical treatment, patients with flexor digitorum profundus avulsion fractures should be referred to a hand specialist. Cepela DJ, Tartaglione JP, Dooley TP, Patel PN. The proximal radius and ulna maintain a normal relationship with respect to the epiphysis; hence, the forearm bones are also displaced relative to the humeral metaphysis. Distal Phalanx Fracture Nondisplaced or minimally displaced (< 2 mm) lateral condyle fractures, may be stratified according to their risk of subsequent displacement. A 4-year-old child with medial epicondyle fracture. In supracondylar fractures with medial displacement of the distal fragment, there is often internal rotation, which results in varus if the fracture is oblique. There are pros and cons to all treatment options. The long finger is the most Lattanza LL, Keese G. Elbow instability in children. distal phalanx fracture; percutaneous pinning; emergency department; hypodermic needle. Functional outcome of the elbow in toddlers with transphyseal fracture of the distal humerus treated surgically. J Shoulder Elbow Surg. Epub 2017 Sep 28. Combined lateral condyle and olecranon fractures. Common Finger Fractures and Dislocations | AAFP Several types of fractures can involve the phalanx or the intra-articular surface.
