Displaced and angulated fractures need referral to hand surgery. 2012 Jul-Aug. 32(5):477-82. 1964. The thumb also has several nerves that give you feeling and blood vessels that provide the thumb with blood flow. (B) Lateral view. Subtle lateral condyle fracture. 45 (2):140-144. J Bone Joint Surg Am. If the medial epicondyle is not seen in its normal anatomic position, it should be searched for elsewhere, including within the elbow joint. Monteggia fracture/dislocation involves dislocation of the radial head accompanied by fracture of the proximal or mid ulna, with the apex of the ulnar fracture pointing in the same direction as the radial head dislocation. Reduction of a dorsal PIP dislocation should be attempted at the time of injury, if possible, by applying traction and volar pressure on the middle phalanx at the PIP joint (Figure 1). Anterior displacement of most of the distal ulna relative to the wrist is due to a distal ulnar growth plate fracture, with anterior displacement of the metaphysis relative to the epiphysis, which still articulates normally with the wrist. see full revision history and disclosures, Gustilo Anderson classification (compound fracture), Anderson and Montesano classification of occipital condyle fractures, Traynelis classification of atlanto-occipital dissociation, longitudinal versus transverse petrous temporal bone fracture, naso-orbitoethmoid (NOE) complex fracture, cervical spine fracture classification systems, AO classification of upper cervical injuries, subaxial cervical spine injury classification (SLIC), thoracolumbar spinal fracture classification systems, AO classification of thoracolumbar injuries, thoracolumbar injury classification and severity score (TLICS), Rockwood classification (acromioclavicular joint injury), Neer classification (proximal humeral fracture), AO classification (proximal humeral fracture), AO/OTA classification of distal humeral fractures, Milch classification (lateral humeral condyle fracture), Weiss classification (lateral humeral condyle fracture), Bado classification of Monteggia fracture-dislocations (radius-ulna), Mason classification (radial head fracture), Frykman classification (distal radial fracture), Hintermann classification (gamekeeper's thumb), Eaton classification (volar plate avulsion injury), Keifhaber-Stern classification (volar plate avulsion injury), Judet and Letournel classification (acetabular fracture), Harris classification (acetebular fracture), Young and Burgess classification of pelvic ring fractures, Pipkin classification (femoral head fracture), American Academy of Orthopedic Surgeons classification (periprosthetic hip fracture), Cooke and Newman classification (periprosthetic hip fracture), Johansson classification (periprosthetic hip fracture), Vancouver classification (periprosthetic hip fracture), Winquist classification (femoral shaft fracture), Schatzker classification (tibial plateau fracture), AO classification of distal femur fractures, Lauge-Hansen classification (ankle injury), Danis-Weber classification (ankle fracture), Berndt and Harty classification (osteochondral lesions of the talus), Sanders CT classification (calcaneal fracture), Hawkins classification (talar neck fracture), anterior superior iliac spine (ASIS) avulsion, anterior cruciate ligament avulsion fracture, posterior cruciate ligament avulsion fracture, avulsion fracture of the proximal 5th metatarsal, lucent fracture line extending through metaphysis, across physis and into the epiphysis, angulation, displacement and rotation may occur, adjacent soft tissue swelling and joint effusion may be noted, CT imaging has a role in evaluating the degree of displacement and anatomic extent of Salter-Harris type IV fractures and can subsequently guide operative intervention, CT imaging can also be incorporated to evaluate focal osseous bridging across the physis during the healing process (most common in Salter-Harris IV and V injuries), 1. Pain and swelling: Take your normal painkillers if you are in pain. When proximal radial fractures occur in children, they primarily involve the radial neck. 41 (7):1453-1461. A 4-year-old child with medial epicondyle fracture. 1) and a protective splint was placed. According to the authors, referral to a nerve specialist following supracondylar fractures is recommended in cases of complete nerve palsy, a positive Tinel sign, or neuropathic pain or vascular compromise. 1998. However, the displacement may also be lateral, as shown in the image below. Distal phalanx fractures are stable and can be treated with simple splinting of the DIP joint only. Because the lateral crista of the trochlea is often included in the fracture fragment, the elbow joint loses lateral support in lateral condyle fractures. 23 (3):318-26. ("Articular" means "joint.") The articular portion of the ulna is formed by the olecranon process proximally and by the coronoid process more distally. In transphyseal fractures, radiocapitellar alignment remains normal, whereas in lateral condyle fractures, the distal fragment is often displaced or rotated, as described above, with alteration of the radiocapitellar alignment. Additionally, it is the orientation of the neck rather than the shaft that should be used to evaluate radiocapitellar alignment. Kim HH, Gauguet JM. [45] It has also been suggested that extension force in infants may be more likely to cause a transphyseal fracture than supracondylar fracture. In addition, traction from the common extensor muscles leads to rotation so that the cartilage-covered articular surface of the fractured lateral condyle is in contact with the metaphysis, leading to nonunion if not corrected. Like the other long bones in the hands, each distal phalanx is separated into a head, body or shaft, and a base [3]. J Bone Joint Surg Am. Log Guidelines for Orthopaedic Trauma A nondegenerative injury was seen in 27.5%, and 67.9% were degenerative injuries. In other patients, the fracture is best seen at the proximal tip of the olecranon metaphysis, as depicted in the image below. In the radiographic evaluation of pediatric elbow trauma, it is important to assess the status of the medial epicondyle, particularly after an elbow dislocation. It usually involves injury to the volar plate and may include a volar plate avulsion fracture. The authors declare that they have nothing to disclose. Other fractures that may be associated with elbow dislocations include fractures of the proximal radius, particularly fractures in which the radial head is markedly displaced and rotated into the coronal plane; fractures of the lateral condyle; and remote fractures in the same extremity, most often the distal radius and ulna. JAMES R. BORCHERS, MD, MPH, AND THOMAS M. BEST, MD, PhD. 32(4):373-7. 22(2):188-93. These injuries are due to valgus rather than varus stress and distract the physis starting medially. This site needs JavaScript to work properly. [QxMD MEDLINE Link]. Lateral view in a patient with osteogenesis imperfecta who has had bilateral recurrent fractures in the same region. In infants, the distal humeral physis has a flat transverse configuration without the stability afforded by a V-shaped configuration in older children. Fractures and dislocations involving the distal phalanx are frequently treated with immobilization, however particular injury patterns warrant additional stabilization. Skaggs DL, Mirzayan R.

Displaced fractures of the neck of the radius. 1978 Jul. Zhou H, Zhang G, Li M, Qu X, Cao Y, Liu X, Zhang Y. J Orthop Surg Res. In cases in which it is clinically indicated, cubitus varus may be corrected by valgus osteotomy. Closed reduction and percutaneous pinning techniques similar to those used for supracondylar humerus fractures are employed. However, this can be challenging for the surgeons schedule, patients schedule, and can also place unnecessary financial burden on the health care system. Medscape Education. [7] Knowledge of the mechanisms of injury, the range of skeletal and soft tissue findings in the different patterns of injury, and the proper indications for additional views all aid in the recognition of subtle fractures. Beaty JH, Kasser JR. Highlight selected keywords in the article text. This view also demonstrates the normal angulation between the radial neck and shaft. Displaced proximal radial fracture. Radiography also helps identify volar fracture of the middle phalanx and other associated injuries. An anteroposterior tomogram (D) obtained at that time shows both the displacement and the course of the fracture line through the epiphysis to the articular surface of the trochlea. In most cases, neurological deficit recover in a few months. Olecranon fracture. Often associated with nailbed injuries that would require evaluation and repair 4. The assessment should also include finger alignment, ligament integrity, neurovascular status, and flexion and extension of the joints. [5] On lateral views, cortical disruption is usually seen posteriorly rather than anteriorly, as with supracondylar fractures (see the image below). Typical supracondylar 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. A thumb fracture may also happen in sports when a ball catches and pulls the thumb back. Arthritis can result in limited joint motion and pain in the joint. WebDistal phalanx fractures are often seen following crush injuries of the fingertips at home or in the work-place. J Pediatr Orthop. [43] Nonunion often leads to valgus deformity from a lateral shift of the fracture fragment. Under conscious sedation and digital block, a Seymour-type exposure3 was utilized to achieve reduction. Typical supracondylar fracture. Transphyseal Distal (B) The lateral view shows posterior displacement and angulation of the distal fragments, appearing similar to a type III supracondylar fracture. 17.1 ). A role for 3-D kinematic analysis of CT and MRI imaging for evaluation of lateral condyle fracture with nonunion has also been proposed If you log out, you will be required to enter your username and password the next time you visit. WebYou have broken your distal phalanx (the end of your finger). If these fractures are stable, they can be treated nonoperatively with splintage. 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. 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. Most cases of isolated radial head dislocation in children are likely to actually be Monteggia fracture/dislocation with a subtle ulnar bowing fracture. Anteroposterior view shows an obvious lateral condyle fracture with lateral displacement of the fragment, rotation, and downward displacement caused by muscular traction. Curr Opin Pediatr. (2017) RadioGraphics. (B) Lateral intraoperative image shows reduction and pinning of the fracture, which is well aligned. These may have some angulation but no true displacement of the fracture fragment and no shift of the olecranon. Initial anteroposterior (A) and lateral (B) views show an obvious lateral condyle fracture and a relatively subtle olecranon fracture. 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. Transphyseal fracture (also called transcondylar fracture) is a fracture through the distal humeral physis that separates the entire distal humeral epiphysis from the metaphysis. Most supracondylar fractures involve posterior displacement or angulation of the distal fragment. A 38-year-old right hand dominant female presented to the ED after sustaining an open fracture of the left small finger distal phalanx when it was caught in the rotary blade of a bread cutter at work. MRI could demonstrate the abnormal relationship of the radial head and annular ligament, but such studies are seldom needed. This is particularly helpful in the distal tibia when the plain film can under-estimate the complexity and severity of a distal tibial injury. Initial anteroposterior (A) and lateral (B) views show a nondisplaced lateral condyle fracture. The extensor pollicis longus (EPL), located on the back side of the thumb, which allows you to straighten your thumb. An avulsion fracture (Figure 5) typically results from forced hyperextension of a flexed DIP joint. Evaluation of displacement of the medial epicondyle may also be aided by recent data regarding the position of the normal medial epicondyle relative to other distal humeral landmarks. 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 much less common flexion-type supracondylar fracture is usually caused by a direct blow to the posterior aspect of the elbow, usually from a fall onto the elbow. 2010 Apr-May. Transphyseal Distal 4. Lateral condyle and olecranon fractures. Although acute nerve injury is rare, elbow deformity following lateral condyle fracture may lead to ulnar neuritis (tardy ulnar palsy), a late complication (average interval from injury = 22 years). 1-6. The distal fracture fragment is displaced laterally and posteriorly. Check for errors and try again. Salter-Harris type IV injuries will often follow typical location patterns and most commonly involve the distal radius, phalanges and distal tibia. Relationship of the anterior humeral line to the capitellar ossific nucleus: variability with age. Rogers LF. Supracondylar fracture. Reliability of a modified Gartland classification of supracondylar humerus fractures. In some cases, the fracture may extend into the metaphysis, producing a Salter-Harris type II injury. Radiographic findings in supracondylar fracture. Cepela DJ, Tartaglione JP, Dooley TP, Patel PN. Most common fracture of the hand. A pulled elbowis a distraction injury. Initial anteroposterior (A) and lateral (B) views show a nondisplaced lateral condyle fracture. The most common of these in the thumb are fractures involving the base of the first metacarpal, affecting the CMC joint where the thumb connects to the wrist: Fractures of the thumb metacarpal can also occur in the long portion of the bone, which is called the metacarpal shaft. After spontaneous reduction, prior elbow dislocation may be suggested by the identification of the fractures described above. Clinically, obliquity is important because rotation along an oblique fracture line leads to varus or valgus in addition to deformity. This technique has not been previously described in the Orthopedic literature for diverse pattern of fractures of the distal phalanx. 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). The possibility of concomitant fracture or soft tissue injury must be considered, especially if relocation is unsuccessful. [QxMD MEDLINE Link]. encoded search term (Imaging in Pediatric Elbow Trauma) and Imaging in Pediatric Elbow Trauma. In the closed crush fracture of the distal phalanx, the L-shaped Alumafoam splint placed on the volar aspect to protect the soft tissues is considered the best distal phalanx fracture; percutaneous pinning; emergency department; hypodermic needle. Accessibility 98-B (6):851-856. [29, 30] : Type 1 - Fractures with no or minimal posterior displacement or angulation of the distal fragment such that the anterior humeral line still intersects part of the capitellum, Type 2 - Fractures with more posterior displacement or angulation, but with an intact posterior cortex; type 2 fractures have been divided into type 2A, with no rotation or translation, and type 2B, with some rotation or translation in addition to posterior displacement and angulation, Type 3 - Fractures with displacement and complete cortical disruption (see the image below), Type 4 - Fractures with displacement, complete cortical disruption, and complete loss of the periosteal hinge anteriorly and posteriorly leading to multidirectional instability. The elbow is composed of 3 articulations. Anteroposterior (A) and lateral (B) views show significant lateral and posterior displacement of a distal fragment. In a Monteggia fracture type 3, the radial head is dislocated, primarily laterally and slightly anteriorly. It is believed that the most common injuries found in association with olecranon fractures are fractures of the proximal radius. 2. These fractures are Nerve injuries may complicate supracondylar fractures. Regenerative Medicine Approaches for the Treatment of Pediatric Physeal Injuries. The incidence of distraction fractures is particularly high in patients with osteogenesis imperfecta, including patients with relatively normal-appearing bones and few fractures elsewhere (see the image below). With type C fractures, the fracture line remains is as wide medially as laterally. These fractures are Anteroposterior (A) and lateral (B) views of the injured right elbow compared with anteroposterior (C) and lateral (D) views of the uninjured left elbow. The alignment was confirmed by clinical examination and fluoroscopy. According to Rabiner et al, ultrasonography is highly sensitive for elbow fractures, and a negative ultrasound may reduce the need for radiographs in children with elbow injuries. Fractures of the proximal phalanx can be complex owing to forces exerted on the fracture fragments by multiple muscles and tendons which often result in angular The effect of humeral length visualized on the x-ray. Olecranon avulsion fracture. Epub 2017 Sep 28. MRI is useful in identifying medial epicondyle fractures prior to ossification of the medial epicondyle and for delineating the full extent of the cartilaginous fracture in children with a small medial epicondyle ossification center. Radiograph anteroposterior view taken in the day of the trauma. Fracture, traumatic (A) Initial anteroposterior view shows typical medial displacement of the capitellum and forearm bones. CRPP is a common technique to manage these injuries and is usually performed in the operating room (OR) setting using Kirshner wires (k-wires) under local anesthesia or a peripheral nerve block. Dynamic assessment with US is effective for diagnosing nerve or muscle subluxation. Rotation is assessed after a finger fracture by active flexion; there should be no digital overlap. [48]. [QxMD MEDLINE Link]. This relation should be examined on a frontal view as well. These deformities may cause posttraumatic arthritis with pain and diminished range of motion, which are often not correctable.

Burr, MD, at [emailprotected] or by mail at Department of Orthopaedic Surgery and Rehabilitation, Loyola University Medical Center Maywood, IL 60153. Treatment consists of splinting in slight flexion with early range of motion and strengthening exercises. WebMost fractures of the distal phalanx can be treated nonoperatively. Other views may also be helpful, such as the internal oblique view for lateral condyle fractures. Distal Phalanx Fractures [46] Some proximal radial fractures may result in abnormal articulation of the radial head and capitellum and therefore are fracture/dislocations. Lateral condyle fractures may be associated with other elbow fractures. Transphyseal elbow fracture in newborn: review of literature. Shukla M, Keller R, Marshall N, Ahmed H, Scher C, Moutzouros VB, et al. However, this finding may cause the injury to be confused with a lateral condyle fracture. J Trauma. In the remainder of patients, fractures/dislocations are divided equally between posterior (Monteggia type 2 injury) and lateral (Monteggia type 3 injury) dislocation of the radial head. 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. They will also: If the bone fragments of the fracture have not moved (displaced) very much, or if the break is located in the middle (shaft) of the bone, your surgeon may be able to treat the thumb fracture without surgery using a specially designed cast (spica cast) to hold the bone fragments in place. Surgery for nailbed repair and/or Kirschner wire fixation will be required in more complex cases. A systematic approach to the finger examination avoids missed diagnoses, potential complications, and poor outcomes. Radiographic findings in lateral condyle fracture. [QxMD MEDLINE Link]. Chicago, IL: Year Book Medical Publishers, Inc; 1985. Most medial epicondyle fractures are avulsion injuries caused by traction from the ulnar collateral ligament or the forearm flexor muscles that arise from the medial epicondyle. Donnelly L, Klostermeier T, Klosterman L. Traumatic elbow effusions in pediatric patients: are occult fractures the rule?. See Instructions for Authors for a complete description of levels of evidence. This website also contains material copyrighted by 3rd parties. The normal apophysis may have separate ossifications centers near its tip. Saeed W, Waseem M. Fracture, Elbow. The even better news for coders? Peterson JJ, Bancroft LW. Distal A padded splint can be used to prevent the bone from moving farther out of alignment. The next bone is called the proximal phalanx. [QxMD MEDLINE Link]. [Closed reduction and percutaneous pinning with three Kirschner wires in children with type III displaced supracondylar fractures of the humerus]. Cost and complications of percutaneous fixation of hand fractures in a procedure room versus the operating room. The anterior humeral line may be extremely useful in the diagnosis of supracondylar fracture. 2015 Sep;99 Suppl 1:S99-105. Volar plate fractures may be small and can be treated conservatively. 7th Ed. In particular situations, such as with young children, conscious sedation can be provided by ED physicians to make the procedure more tolerable. Salter-Harris fracturesare a group childhood injuries where a fracture involves the physis. 7. van Leeuwen WF, van Hoorn BT, Chen N, et al. The ulna articulates with the humerus at the trochlea, which is the grooved and rounded medial articular portion of the distal humerus. Prognostic Level III. Leitch KK, Kay RM, Femino JD, Tolo VT, Storer SK, Skaggs DL. 2017 Feb 20. While previously supracondylar fractures were more frequent in boy than in girls, this discrepancy has diminished. In particular, if undergoing an outpatient procedure rather than ER procedure, the patient may need to take additional time off for a preoperative clinic visit and for the surgery. Okumura Y, Maldonado N, Lennon K, McCarty B, Underwood P, Nelson M. Point-of-Care Ultrasound: Sonographic Posterior Fat Pad Sign: ACase Report and Brief Literature Review. The decision to remove the pin at this time point was based on the absence of tenderness at the fracture site and stable appearance on x-rays. The capitellar ossification center eventually extends beyond the capitellum into the lateral aspect of the trochlea and accounts for ossification of the lateral crista of the trochlea. WebAbstract. The dashed radiocapitellar line is drawn through the radial neck and should pass through the capitellum. Subsequent views (C and D) show lateral and posterior displacement of a distal fragment. Silverman FN. Assessment of stability is necessary for appropriate management of dislocated joints. Note associated proximal radial metaphyseal fracture. In addition to the findings in the multiple ossification centers described above, other normal findings may simulate pathology. A unique physeal injury of the distal phalanx - PMC T1-weighted MRi showx lack of osseous union. Following reduction of a proximal interphalangeal dislocation, short-term splinting in flexion with early active range of motion and strengthening is preferable to prolonged immobilization. 1987 Jul 11. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. In those cases in which vascular injury is recognized, reduction usually corrects the vascular abnormality, and hence reduction and pinning should not be delayed for arteriographic assessment. [28] See the images below. Stability of the reduction is assessed by gentle active flexion of the involved finger; the joint should be stable through flexion and extension. Rha E, Lee M, Lee J, et al. In this patient, the uninjured right elbow has a Baumann angle of 12, and the previously injured left elbow has a Baumann angle of only 2, suggesting 10 of varus deformity of the left distal humerus. [36, 37]. 50:95. 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. In young patients with a nonossified or only partially ossified trochlea, the epiphyseal component of the fracture is not visible, and only the metaphyseal flake is identifiable. Radiographic findings of elbow dislocation. 2018 Jan. [QxMD MEDLINE Link]. Radiographs showed a physeal injury of the distal phalanx with an 3. DeFroda SF, Hansen H, Gil JA, Hawari AH, Cruz AI Jr. Radiographic Evaluation of Common Pediatric Elbow Injuries. Therefore, elbow radiographic findings are normal in a pulled elbow. To limit these complications, we wanted to explore the benefits of using locked extra-articular DIP pinning. Distal Fracture Referral is recommended for complicated injuries.
