In supracondylar fractures with medial displacement of the distal fragment, there is often internal rotation, which results in varus if the fracture is oblique. Fractures of the proximal ulna are uncommon in children, accounting for 6% of elbow fractures. Philadelphia, PA: JB Lippincott; 1983. The smooth end of the ulna is the metaphysis ending at the physial fracture. Radial head displacement or injury to the proximal radial growth plate may cause growth arrest, leading to radial shortening that may affect alignment of the wrist. Beaty JH, Kasser JR. Rockwood and Wilkins' Fractures in Children. A major complication of a radial neck fracture is limitation of motion at the proximal radioulnar joint, which mostly limits supination. Is Bone Mineral Density Testing Underused in Prostate Cancer Care? Kuhn MA, Ross G. Acute elbow dislocations. Splinting in extension for two to three weeks is the typical nonoperative treatment. 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. [QxMD MEDLINE Link]. This is sometimes called a tuft fracture Healing: This normally takes approximately 4-6 weeks to heal. 171:243-245. Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi. 2013 Jan. 61(1):9-17. Semin Ultrasound CT MR. 2018 Aug. 39 (4):384-396. Please try again soon. The radial head ossification center is initially oval and subsequently becomes flattened and disk shaped. 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). Finger fractures and dislocations may occur during daily activities, such as work, but usually occur during participation in sporting activities. Some common finger fractures can be treated conservatively with appropriate reduction and immobilization. The bones of the hand and wrist are shown in the figure ( figure 1 ). This complication is usually caused by malalignment of the radial head and neck; more severe limitation of motion may result from radioulnar synostosis.

Operative treatment of selected fractures of the childs hand. 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 83-A(5):735-40. On the lateral view, the distal ulnar epiphysis is largely obscured by the distal radius. [QxMD MEDLINE Link]. J Bone Joint Surg Am. Olecranon fracture. 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). However, these injuries have marked medial soft tissue swelling compared with the lateral soft tissue findings with lateral condyle fracture. Several types of fractures can involve the phalanx or the intra-articular surface. Federal government websites often end in .gov or .mil. Note the normal notchlike step off of the lateral aspect of the proximal radial metaphysis. Unlike supracondylar fractures, vascular and neurologic complications are extremely rare with lateral condyle fractures. J Shoulder Elbow Surg. A more recent article on common finger fractures and dislocations is available. 8600 Rockville Pike 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. 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. Treatment is generally straightforward, with excellent outcomes. Reliability of a modified Gartland classification of supracondylar humerus fractures. The avulsed proximal fracture fragment is proximally retracted by the triceps muscle. John J Grayhack, MD, MS is a member of the following medical societies: American Academy of Orthopaedic SurgeonsDisclosure: Nothing to disclose. Initial evaluation of vascular injury is clinical. Reduction may be unsuccessful because of soft tissue injury or fracture. Fracture-dislocation of the elbow. [QxMD MEDLINE Link]. On the frontal view, supracondylar fractures typically extend transversely through the metaphysis across the region of the olecranon fossa. If there is instability or significant rotation, referral to a hand surgeon is required. [QxMD MEDLINE Link]. 4B, hyperflexion injury with fracture of articular surface of 20% to 50%. The elbow should be well visualized in all patients who have an ulnar injury, with or without an associated radial fracture. [QxMD MEDLINE Link]. Oblique views may be required to depict these fractures, since some are not apparent on AP views. Lateral condyle and olecranon fractures. government site. Common signs of injury are local swelling, erythema, pain, deformity, and tenderness to palpation. [18]. We propose that fracture stabilization can be performed by the on-call hand resident or fellow in the ER. [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. 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. 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. Anteroposterior (A) and lateral (B) views. 1975 Dec. 57(8):1087-92. On the lateral view, a clue that is helpful in recognizing entrapment of the medial epicondyle is widening of the medial joint space. The technique is cost and time effective when treating patients with this type of injury. Unauthorized use of these marks is strictly prohibited. Kim HT, Song MB, Conjares JN, Yoo CI. [QxMD MEDLINE Link]. Complications of lateral condyle fracture. Although not directly analogous, this is one example of the cost disparities associated with performing a procedure in the ER versus OR. J Bone Joint Surg Am. The rest of the radius appears dislocated with respect to the capitellum; however, this is a displaced fracture rather than a dislocation (see the image below). Kuoppala E, Parviainen R, Pokka T, Sirvi M, Serlo W, Sinikumpu JJ. Conversely, ulnar fractures in a child are often accompanied by a radial fracture or dislocation, even if the ulnar fracture is a relatively subtle greenstick injury. [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. Typically, an 18 (outer diameter 1.270mm) or 20-G needle (outer diameter 0.908mm) can be used for an adult. The pin was removed at her 6-week follow-up, at which time there was some early consolidation of the fracture on imaging. (2010) Clinical radiology. Lateral condyle fracture passing through the ossified portion of the capitellum. Wolters Kluwer Health Failure of the radiocapitellar line to pass through the capitellum indicates radiocapitellar 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. Reduction is similar to that of a dorsal PIP dislocation if no concomitant injury is present. Because the entrapped medial epicondyle is positioned just distal to the medial side of the distal humeral metaphysis, it may be misinterpreted as the ossification center for the trochlea. Overall, many thumb fractures have good outcomes after appropriate treatment. In the study, after clinical examination and before radiography, pediatric emergency physicians performed elbow US of the posterior fat pad and determined whether radiography was required. The anterior fat pad is demonstrated and is abnormally elevated. In addition to the findings in the multiple ossification centers described above, other normal findings may simulate pathology. (A) Note the avulsion of the medial epicondyle, which projects just distal to the trochlea on the anteroposterior view. To limit these complications, we wanted to explore the benefits of using locked extra-articular DIP pinning. WebDistal phalanx fractures are often seen following crush injuries of the fingertips at home or in the work-place. This information is provided as an educational service and is not intended to serve as medical advice. J Child Orthop. Reduction is often successful without anesthesia. 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. Stage II fractures extend through the articular surface, allowing for a small amount of displacement of the distal fragment and olecranon shift. Other views may also be helpful, such as the internal oblique view for lateral condyle fractures. Please enable scripts and reload this page. 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. Rabiner JE, Khine H, Avner JR, Friedman LM, Tsung JW. However, additional morbidity includes a predisposition to subsequent lateral condyle fracture, pain, and late development of posterolateral elbow instability. Salter-Harris type IV injuries will often follow typical location patterns and most commonly involve the distal radius, phalanges and distal tibia. All rights reserved. Monteggia fracture type I. Lateral view of injured forearm (A) shows anterior dislocation of the radial head and convex anterior bowing of the ulna, which is most apparent when compared with the contralateral uninjured forearm (B). Hence, lateral condyle fractures are Salter-Harris type IV injuries, even though they often have the radiographic appearance of a Salter-Harris type II injury. Anteroposterior (A) and lateral (B) views show combined fractures of the distal humeral lateral condyle and olecranon process of the ulna. 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.
