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. Often associated with nailbed injuries that would require evaluation and repair 4. Fractures of the proximal ulna are uncommon in children, accounting for 6% of elbow fractures. Garon MT, Massey P, Chen A, et al. Cost and complications of percutaneous fixation of hand fractures in a procedure room versus the operating room. 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. One patient did experience stiffness of the injured finger which improved with therapy. The other bones of the thumb the distal phalanx and proximal phalanx are also susceptible to fractures. 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. 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. Proper Technique for Reduction of Metacarpophalangeal Dislocations. The avulsed proximal fracture fragment is proximally retracted by the triceps muscle. Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi. See the Medscape Reference article Salter-Harris Fracture Imaging for more information. WebRadial/Ulnar shaft fractures 813.1 Distal Radius Fracture 813.42 Distal Ulna Fracture 813.82 Carpal Fracture 814.01 Metacarpal Fracture 815.0 Phalanx Fractures 816.0 Forearm/Wrist Fractures Radius fractures: Radial head (may require a prosthesis) Midshaft radius Distal radius (most common) Cepela DJ, Tartaglione JP, Dooley TP, Patel PN. Non-accidental Trauma 295(6590):109-10. Typically, the most concerning and problematic broken bones involve the joints. 2001 May. The lucent cleft in the fracture fragment is the normal olecranon growth plate. The patient followed up at 2 weeks for a wound check and again at 4 weeks for pin removal. Abzug JM, O'TYoole RV, Paryavi E, Sterling R. Are orthopaedic residents competent at performing basic nonoperative procedures in an unsupervised setting? Salter Harris Fractures. [22] Nonunion has been considered to be more of a problem in patients with minimally displaced fractures than in patients with significant displacement, presumably because the lack of surgical fixation allows a small amount of motion and because of the development of fibrocartilage between the fragments. Fig.1. Injury, postreduction, and follow-up x-rays are shown in Figure 3. The https:// ensures that you are connecting to the Even incomplete fractures often have enough disruption in 1 of the cortices (usually the anterior cortex) to make diagnosis easy (see the image below). Normal radial tuberosity. 7. van Leeuwen WF, van Hoorn BT, Chen N, et al. Our patients experienced no pin tract infections, nail defects, or sensation issues. Rarely, the medial epicondyle may also be fractured by direct trauma. At our institution, pediatric patients undergo conscious sedation for irrigation and debridement and nail bed repairs in almost every scenario. {"url":"/signup-modal-props.json?lang=us"}, O'Graphy T, El-Feky M, Qureshi P, et al. Stability of the reduction is assessed by gentle active flexion of the involved finger; the joint should be stable through flexion and extension. 2012 Feb. 20(2):69-77. Chicago, IL: Year Book Medical Publishers, Inc; 1985. Radiograph anteroposterior view taken in the day of the trauma. Reproduced with permission from Soyer AD: Fractures of the Base of the First Metacarpal: Current Treatment Options. Recognizing that the forearm is not aligned with the humerus on plain radiography can aid in the diagnosis of the injury. The flexor digitorum profundus tendon inserts at the volar surface of the distal phalanx. Finger fractures involving greater than 30 percent of the intra-articular surface should be referred to an orthopedic or hand surgeon. Wheeler DK, Lindscheid RL. WebFractures of the distal phalanx are the most common fractures in the hand. 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. Am J Sports Med. Open Fracture Reduction Distal Fracture Fracture rotation can be difficult to assess radiologically and is best assessed on clinical examination. Features that help in distinguishing between transphyseal and lateral condyle fractures include alignment of the radiocapitellar joint and the direction of displacement. The orientation of the fracture line in the sagittal plane has both diagnostic and clinical implications. WebINTRA ARTICULAR DISTAL HUMERUS FRACTURE 24546 Open treatment of humeral supracondylar or transcondylar fracture, includes internal fixation when performed; with intercondylar extension PELVIC RING ACETABULUM BICONDYLAR TIBIAL PLATEAU 27536 Open treatment of tibial fracture, proximal (plateau); bicondylar, with or without A corrective lateral closing wedge osteotomy can be performed to restore a nearly normal carrying angle. There are pros and cons to all treatment options. 2007 Jan. 89(1):58-63. Volar plate fractures may be small and can be treated conservatively. (B) Anteroposterior contralateral comparison. The most common follow-up fractures were olecranon (N=23, 72%), coronoid process (N=4, 13%), and supracondylar (N=3, 9%). Some institutions attempt to circumvent these challenges by running a dedicated procedure room within the emergency room (ER) for these procedures. 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. Hand Clin. Please confirm that you would like to log out of Medscape. 2008 Feb. 24(1):139-52. An end-result study. Note the pseudoarthrosis of the distal phalanx of the fourth toe Fig.3. The fracture originates in the lateral aspect of the distal humeral metaphysis and passes obliquely to the physis. Prevention and treatment of non-union of slightly displaced fractures of the lateral humeral condyle in children. For example, the medial epicondyle usually ossifies prior to the trochlea. Other causes of transphyseal fractures of the distal humerus include nonaccidental trauma and fall from a low level height [4-7]. 9 (1):7030. Rogers LF, Malave S Jr, White H, Tachdjian MO. 2018;13:428434. WebThe doctor will take an X-ray of the wrist. Internal oblique radiographs for diagnosis of nondisplaced or minimally displaced lateral condylar fractures of the humerus in children. Elbow dislocations are usually readily apparent on radiographs. 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. A variety of treatment modalities exist for distal phalanx fractures Babal JC, Mehlman CT, Klein G. Nerve injuries associated with pediatric supracondylar humeral fractures: a meta-analysis. Central slip injury can lead to the inability to extend the finger at the PIP joint and hyperflexion or boutonnire deformity over time.11 These injuries should be splinted for six weeks in full PIP extension to avoid chronic deformity at the PIP joint.11 Volar PIP dislocations are more difficult to reduce and results should be confirmed with postreduction radiography. This view also demonstrates the normal angulation between the radial neck and shaft. These injuries should be suspected with gross deformity on inspection of the middle or proximal phalanx. See the image below. Reduction may be unsuccessful because of soft tissue injury or fracture. However, such an injury may be suggested by localized tenderness and soft tissue swelling and by the presence of a posterolateral elbow dislocation. The radial fracture is so close to the joint that the injury may superficially resemble a radial head dislocation. The distal ulnar epiphysis is best depicted on the anteroposterior view, on which it is seen to overlap the ulnar metaphysis. 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. Malays Fam Physician. Kuhn MA, Ross G. Acute elbow dislocations. [23] Radiographic evaluation of the amount of displacement is also known to be limited, with many cases showing substantially more displacement by CT than radiography. Krengel WF 3rd, Wiater BP, Pace JL, Jinguji TM, Bompadre V, Stults JK, et al. Stress radiographs demonstrating widening of the medial joint space with valgus stress indicate either avulsion of the medial epicondyle or disruption of the ulnar collateral ligament. The pin was removed at her 6-week follow-up, at which time there was some early consolidation of the fracture on imaging. On the frontal view, supracondylar fractures typically extend transversely through the metaphysis across the region of the olecranon fossa. At the time the article was last revised Mostafa El-Feky had T-condylar fracture in 15-year-old youth. Broken fingers generally heal well after treatment and rehabilitation. Does using the medial or lateral humeral line improve reliability of Baumann angle measurement on plain x-ray? Localized soft tissue swelling is usually present. Traditional treatment following reduction of uncomplicated dorsal PIP joint dislocations is splinting for one to two weeks followed by buddy taping for another one to two weeks.

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. The Elbow: Physeal Fractures, Apophyseal Injuries of the Distal Humerus, Osteonecrosis of the Trochlea, and T-Condylar Fractures. Radiographic findings in lateral condyle fracture. 3. Distal phalanx fractures are often seen following crush injuries of the fingertips at home or in the work-place. Referral is recommended for fracture involving greater than 30 to 40 percent of the intra-articular surface, if reduction is difficult or unsuccessful, or if the patient is unable to achieve full extension following reduction. Most common fracture of the hand. [38, 1, 39]. The distal phalanx is the most commonly fractured bone of the hand. Epub 2015 May 10. 4:592-607. Vascular complications are less common than neurologic injury and are usually accompanied by severe injuries, often including open fractures. A 20-G needle is typically used in pediatric injuries as well, however a smaller needle could be considered occasionally for smaller patients. Distal phalanx fractures are stable and can be treated with simple splinting of the DIP joint only. Prompt and accurate diagnosis of the injury is crucial for a successful outcome. On an anteroposterior view obtained after reduction of the lateral condyle fracture (C), the olecranon fracture is more obvious. Review on mallet finger treatment 2015 Feb. 27 (1):58-66. Additional investigation with a larger cases series may be warranted to further evaluate outcomes and complications. Less often, the distal fragment is displaced laterally, and these fractures tend to have external rotation, producing valgus. 1988;13:350352. Zorrilla S de Neira J, Prada-Caizares A, Marti-Ciruelos R, Pretell-Mazzini J. Supracondylar humeral fractures in children: current concepts for management and prognosis. Keyword Highlighting When the proximal radius and ulna return to normal position, the capitellum may shear off the radial head, leaving it posteriorly displaced. Like the other long bones in the hands, each distal phalanx is separated into a head, body or shaft, and a base [3]. J Pediatr Orthop. Supracondylar fractures usually extend transversely across the metaphysis, whereas lateral condyle fractures are oblique and more distal. encoded search term (Imaging in Pediatric Elbow Trauma) and Imaging in Pediatric Elbow Trauma. A broken thumb can be a serious problem. [QxMD MEDLINE Link]. 2016 Apr. WebAbstract. Epub 2017 Sep 28. 4). fractures 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). [QxMD MEDLINE Link]. Donnelly L, Klostermeier T, Klosterman L. Traumatic elbow effusions in pediatric patients: are occult fractures the rule?. The vast majority (98%) of supracondylar fractures are extension injuries that result from a fall on an outstretched arm. They are frequently related to sports, with lesions such as the mallet finger and the Jersey finger. [QxMD MEDLINE Link]. In 55-85% of patients, the radial head is anteriorly dislocated, with an associated apex anterior ulnar fracture (Monteggia type 1 injury). 3. 4B, hyperflexion injury with fracture of articular surface of 20% to 50%. While previously supracondylar fractures were more frequent in boy than in girls, this discrepancy has diminished. The distal humeral articular surface has several grooves and ridges that are important in determining anatomic stability after a fracture. Start appropriate oral antibiotics for any open fractures. WebMost fractures of the distal phalanx can be treated nonoperatively. 2018 May/Jun;38(5):e262-e266. Tissue Eng Part B Rev. Lateral (Monteggia type 3) injuries most often occur in children 5-9 years of age (see the image below). T1-weighted MRi showx lack of osseous union. Peterson JJ, Bancroft LW. When the medial epicondyle is pulled downward (distally) by the forearm flexor muscles, it may enter the medial joint space. [5, 6, 7, 8], Standard radiographic evaluation of the elbow includes imaging in the anteroposterior (AP) and lateral views. Please enable it to take advantage of the complete set of features! 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). To make the diagnosis, it is helpful that the radiologist be familiar with the normal developmental anatomy of the elbow. The articular portion of the ulna is formed by the olecranon process proximally and by the coronoid process more distally. Treatment of multidirectionally unstable supracondylar humeral fractures in children. Entrapment is particularly common after an elbow dislocation or subluxation. The medial and lateral columns are more separated proximally than distally. These fractures are usually Salter-Harris type II injuries that include a metaphyseal fragment of variable size. Splinting for two to four weeks should be followed by range of motion and strengthening of the DIP joint. [43] Nonunion often leads to valgus deformity from a lateral shift of the fracture fragment. (A) On the anteroposterior view, the fracture is seen as a longitudinal lucent line through the medial aspect of the proximal ulna. DaCruz DJ, Slade RJ, Malone W. Fractures of the distal phalanges. Metacarpal fractures are seen more often in adults, whereas phalangeal fractures are more common in children [ 2 ]. In some patients, the finding may be subtle; recognition of this injury requires a high index of suspicion and the use of comparison views of the contralateral forearm, when needed. Reduction of Radiography with Point-of-Care Elbow Ultrasonography for Elbow Trauma in Children. If there is instability or significant rotation, referral to a hand surgeon is required. Growth Plate 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. Passage of the anterior humeral line either anterior to the capitellum or through the anterior third of the capitellum demonstrates that the capitellum is positioned too far posteriorly; this finding indicates a distal humeral fracture. 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. On the lateral view, a clue that is helpful in recognizing entrapment of the medial epicondyle is widening of the medial joint space. On the lateral view, cortical disruption is usually seen posteriorly rather than anteriorly as in supracondylar fractures. Lateral condyle fracture. The overall sensitivity of elbow US was 88%. Your surgeon may use one of several operative fixation techniques to realign the bone fragments. 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. A fracture of the thumb can be held in proper alignment using external fixation.

The long finger is the most A 4-year-old child with medial epicondyle fracture. This website also contains material copyrighted by third parties. In other patients, the fracture is best seen at the proximal tip of the olecranon metaphysis, as depicted in the image below. [3] Clinical feature of these lesions are variable, the glomus tumor present changes in pain severity depending on temperature. 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). 64B:256. Fractures involving greater than 30 to 40 percent of the intra-articular surface, reduction is difficult or unsuccessful, the patient is unable to obtain full extension following reduction, MCP dislocation (especially in the thumb), Reductions requiring anesthesia, open reductions, Conservative treatment is ineffective; large displaced bony fragment or significant volar subluxation, Flexor digitorum profundus avulsion fracture. However, in most patients, the injury is caused by a fall onto a pronated forearm, which forces the arm into hyperpronation. It is imperative that extension is maintained at all times during treatment because any flexion can affect healing and may extend the treatment period.
