Successful management is dependent on an early and accurate diagnosis of the injury, through clinical and radiologic evaluation. Incidence of pin track infections in childrens fractures treated with Kirschner wire fixation. WebDistal phalangeal enchondromas are rare and often difficult to differentiate from epidermal cysts, glomus tumor and osteoid osteoma. As with lateral condyle fractures, these are typically Salter-Harris type IV injuries. Fractures and dislocations of the elbow region. Clinically, obliquity is important because rotation along an oblique fracture line leads to varus or valgus in addition to deformity. Oman Med J. In addition, usually, the trochlea initially appears as multiple fragmented ossification centers; by contrast, the medial epicondyle has a smooth and regular appearance. In one study, 7 out of 606 supracondylar humeral fractures were flexion-type injuries. Even incomplete fractures often have enough disruption in 1 of the cortices (usually the anterior cortex) to make diagnosis easy (see the image below). Web26785 Open treatment of distal phalangeal fracture, finger or thumb, with or without internal or external fixation, each Depth of Plunge CPT Description 23515 Open treatment of clavicular fracture, with or without internal or external fixation 23615 Open treatment of proximal humeral (surgical or anatomical neck) fracture, with or Complications include unstable fixation, K-wire migration, septic arthritis and osteoarthritis. 2016 Jun. 2017 Jun. The most common complication is cubitus varus caused by a malunion, osteonecrosis of the medial condyle, or growth arrest. Master Techniques in Orthopaedic Surgery: The Hand. A fluoroscopic image of the selected needle next to the distal phalanx before insertion can help to confirm the appropriate needle choice. government site. When no displacement is present, findings indicating a lateral condyle fracture may be subtle. The fractured medial epicondyle may become entrapped in the elbow joint, representing a major complication. Lateral condyle fracture. The ulna articulates with the humerus at the trochlea, which is the grooved and rounded medial articular portion of the distal humerus. She was started on a home exercise program at that time. 2017 Aug. 46 (8):1081-1085. Philadelphia, PA: Lippincott Williams & Wilkins; 2015:427438. Common complications of these injuries are: altered sensitivity (numbness, hyperesthesia, tenderness) cold sensitivity (cold intolerance) restriction of DIP joint movement Would you like email updates of new search results? 3. [32] If this does not adequately restore circulation, vascular repair, usually following arteriography, may be needed. On the lateral view, a thin metaphyseal flake is present posteriorly and indicates a Salter-Harris type II injury rather than the usual Salter-Harris type I injury. The long finger is the most The bones of the thumb have several important ligaments at each joint that both allow for motion of the joint and keep the joint stable so it does not dislocate: Several other tendons/muscles allow the thumb to move in virtually all directions. Prompt and accurate diagnosis of a transphyseal distal humerus fracture is crucial for a 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. Before The peak age of occurrence for these fractures is 4-10 years. Carpenter S, Rohde RS. Orthop Clin North Am. Monteggia variant. Relationship of the anterior humeral line to the capitellar ossific nucleus: variability with age.

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. Kuoppala E, Parviainen R, Pokka T, Sirvi M, Serlo W, Sinikumpu JJ. 1. The elbow should be well visualized in all patients who have an ulnar injury, with or without an associated radial fracture. 37 (6): 1791-1812. fractures involving a single facial buttress, Meyers and McKeevers classification (anterior cruciate ligament avulsion fracture), Watson-Jones classification (tibial tuberosity avulsion fracture), Nunley-Vertullo classification (Lisfranc injury), pelvis and lower limb fractures by region. Place in stack splint for protection and pain control for 3 to 4 weeks. 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. Kuhn MA, Ross G. Acute elbow dislocations. Metaphyseal fractures [corner fracture]: Commonly affects the distal femur or the proximal tibia (Fig. Between these grooves is the lateral crista of the trochlea, which provides lateral stability to the trochleoulnar joint. If the medial epicondyle is not seen in its normal anatomic position, it should be searched for elsewhere, including within the elbow joint. 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. Sometimes, thumb fractures can result in joint instability when they involve the important ligaments that keep the joints aligned. Treatment of a mallet fracture includes splinting the distal interphalangeal joint in extension; various splint types are of equal benefit. Fracture rotation can be difficult to assess radiologically and is best assessed on clinical examination. [QxMD MEDLINE Link]. The double density caused by such overlap may simulate a flake of bone, with lucency of the physis simulating an adjacent fracture line. In particular, the internal oblique view has been shown to be better than the AP view for showing the presence of lateral condyle fracture, the degree of displacement, and findings suggesting instability. The distal ulnar epiphysis is best depicted on the anteroposterior view, on which it is seen to overlap the ulnar metaphysis. This complication is usually caused by malalignment of the radial head and neck; more severe limitation of motion may result from radioulnar synostosis. 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. J Pediatr. Differential diagnosis for corner 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. Salter-Harris IV injuries typically have a poor prognosis due to interruption of the proliferative and reserve cartilage zones often leading to altered joint mechanics and functional impairment and as such orthopedic evaluation and subsequent operative intervention are often required 1,2. [QxMD MEDLINE Link]. A systematic physical examination is imperative to avoid complications and poor outcomes following these injuries. [6] Cubitus varus after supracondylar fractures is relatively common and had previously been considered to be primarily a cosmetic problem. It should be borne in mind that transphyseal fractures are associated with child abuse. Medial condyle fracture with markedly rotated distal fragment in a 7-year-old boy. 533-93. (B and C). Compare these images with the lateral view of the contralateral elbow (C), which shows the anterior humeral line passing normally through the middle third of the capitellum. 2007 Jan. 89(1):58-63. The needle can be chosen based on the measurement of the isthmus of the distal phalanx on the lateral view on the injury radiographs. At surgical exploration, the brachial artery was transected at the level of the fracture. 2019 Feb 1;13(1):47-56. doi: 10.1302/1863-2548.13.180156. In supracondylar fractures with medial displacement of the distal fragment, there is often internal rotation, which results in varus if the fracture is oblique. New York: Churchill Livingstone. Radiography is also required following successful reduction to evaluate for subluxation, instability of the PIP joint, and possible volar plate fractures of the middle phalanx. The most common follow-up fractures were olecranon (N=23, 72%), coronoid process (N=4, 13%), and supracondylar (N=3, 9%). You may inquire whether the author(s) will agree to phone conferences and/or visits regarding these techniques. Cubitus varus has also been recognized to result from posttraumatic trochlear deformity, which is likely due to avascular necrosis of the trochlear ossific nuclei or ischemic injury of growth plate chondrocytes following distal humeral fractures, most commonly supracondylar fractures. [QxMD MEDLINE Link]. Initial anteroposterior (A) and lateral (B) views show an obvious lateral condyle fracture and a relatively subtle olecranon fracture. Middle and proximal phalanx fractures are often associated with trauma. [15] : Initial evaluation of chronic elbow pain should begin with radiography. 2018 Sep. 33 (5):444-446. Valgus may also result from malunion, and varus deformity may be caused by malunion or stimulation of growth of the lateral condylar physis. Referral to a hand specialist is required if a fracture is unstable, involves a large portion (greater than 30 percent) of the intra-articular surface, or has significant rotation. Weband phalanx fracture consolidation (Fig. 4:592-607. Closed fractures are generally stable, especially when they do not involve the articular surface. In these cases, only the radial head is still in alignment with the capitellum. J Orthop Trauma. 50:95. Metaphyseal fractures can be undetectable clinically and show only in bone survey. The thumb connects to the hand through the [Guideline] Hayes CW, Roberts CC, et al. http://www.guideline.gov/content.aspx?id=49910&search=elbow, American Society for Bone and Mineral Research, Society of Nuclear Medicine and Molecular Imaging. Percutaneous pinning of distal phalanx fractures in the ED using an 18- or 20-G hypodermic needle is an effective treatment with minimal early complications. J Pediatr Orthop. Normal radiographic findings that may simulate nontraumatic pathology include a radial tuberosity that appears as a lytic lesion when viewed en face (see the image below) and the olecranon fossa of the distal humerus, which may be unusually large and lucent. This motion causes the ulna to fracture and contact the proximal radius, forcing the radial head to become dislocated from the capitellum. Some error has occurred while processing your request. 2nd ed. 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. The incidence of phalangeal fractures is the highest in children aged 10 to 14 years, wh Pediatric Phalanx Fractures from the American Academy of Orthopaedic Surgeons, The flexor pollicis longus (FPL), which runs along the palm side of the thumb and allows you to bend your thumb. Although the Baumann angle usually is defined as the angle between the growth plate for the capitellum and a line drawn perpendicular to the humeral shaft, the need to draw the perpendicular line can be avoided by using the complement of the angle between the capitellar growth plate and the humeral shaft. Medial condyle fracture. While transphyseal distal humerus fractures are rare, the true incidence may be These injuries resemble Salter-Harris type I, III, and II fractures, respectively, though the Salter-Harris classification is usually applied to injuries of the epiphyses rather than those of the apophyses. Edmonds EW. Prior literature has demonstrated effective stabilization of mallet fractures with hypodermic needles2; however, the utility of this technique for other fracture patterns have not been discussed. 2018;13:428434. J Trauma. 65:371-8. Note the abnormal relation of anterior humeral line on the lateral view. Radiology of Skeletal Trauma. Classification of fractures of the thumb. A dorsal PIP dislocation often leads to obvious dorsal deformity of the middle phalanx and volar plate tenderness. 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. AJR. 1990. 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. This is particularly helpful in the distal tibia when the plain film can under-estimate the complexity and severity of a distal tibial injury.

(B) Anteroposterior contralateral comparison. J Pediatr Orthop. Anteroposterior (A) and lateral (B) views. 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. Anteroposterior (A) and lateral (B) views of the injured left elbow with anteroposterior (C) and lateral (D) views of the right elbow for comparison. These deformities may cause posttraumatic arthritis with pain and diminished range of motion, which are often not correctable. 4. See Instructions for Authors for a complete description of levels of evidence. Often, medial displacement accompanies supracondylar fractures. With the elbow fully extended, or hyperextended with relative ligamentous laxity during childhood, the olecranon acts as a fulcrum to transmit the load into a bending force on the distal humerus in the supracondylar region. WebDistal Phalanx Fractures Tuft Fracture (crush injury) Soft tissue injury is often more obvious; Xray required to detect underlying fracture Management consists mainly of Similar to lateral condyle fractures, the fracture continues through the epiphysis, but it cannot be seen in this patient because the entire trochlea is still cartilage and has not yet become ossified. As in all cases of trauma, the importance of recognition of open distal phalanx fractures is due to the increased risk of contamination and, hence, infection. With healing, sclerosis is demonstrated across the entire metaphysis, indicating the full extent of the fracture (see the image below). Copyright 2012 by the American Academy of Family Physicians. WebTransphyseal 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.

The lucent cleft in the fracture fragment is the normal olecranon growth plate. The fracture extends through the metaphysis and into the epiphysis, typically arising just above the medial epicondyle and extending to the trochlear groove, as shown in the image below. The chronologic order of appearance of elbow ossification centers is as follows: capitellum, radial head, medial epicondyle, trochlea, olecranon, and lateral epicondyle at 1, 5, 7, 10, 10, and 11 years, respectively. This typically occurs several years after the injury. [QxMD MEDLINE Link]. Lastly, mini c-arms are now widely available in EDs. Therefore, the flake of bone must represent a fracture fragment. Finger fractures and dislocations are common injuries that are often managed by family physicians. (2010) Clinical radiology. 187:812-817. Less frequently (4 of 48 in Jakob's series), the fracture passes through the lateral aspect of the metaphysis, crosses the physis, and continues through the ossified capitellum, with the typical radiographic appearance of a Salter-Harris type IV fracture (see the image below). [20, 27, 1]. A volar dislocation (Figure 2) can be accompanied by avulsion of the central slip extensor mechanism of the PIP. As a result, accurate and timely radiographic interpretation is essential for alerting the clinical staff to the features of the fractures and the need for orthopedic treatment. Failure to treat PIP dislocations appropriately can lead to chronic pain, degenerative changes, and loss of function. They are frequently related to sports, with lesions such as the mallet finger and the Jersey finger. The bones of the hand and wrist are shown in the figure ( figure 1 ). 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. Unable to load your collection due to an error, Unable to load your delegates due to an error. Radiographic findings of elbow dislocation. Type A fractures have no or minimal gap at their lateral aspect and cannot be traced all of the way to the physis. Krengel WF 3rd, Wiater BP, Pace JL, Jinguji TM, Bompadre V, Stults JK, et al. Table 1 summarizes the evaluation and management of finger dislocations and fractures. Fracture is obvious on both the anteroposterior (A) and lateral (B) views. Normal lines. When proximal radial fractures occur in children, they primarily involve the radial neck.
