Exam and imaging revealed an oblique distal phalanx fracture with an associated volar laceration and nail bed injury. The position of the tiny ossification center for the capitellum suggests that it is displaced posteriorly; this is confirmed on the arthrogram (C). [QxMD MEDLINE Link]. A major complication of a radial neck fracture is limitation of motion at the proximal radioulnar joint, which mostly limits supination. With this in mind, the average age at which the centers are seen first in 50% of children is age 3 months for the capitellum, 5 years for the medial epicondyle, 8 years for the trochlea, and 10 years for the lateral epicondyle. 2010 Dec 1. The distal interphalangeal joints are formed by the articulations between the heads of the middle phalanges and the bases of the distal phalanges. [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. Radiocapitellar alignment remains normal. Initial anteroposterior (A) and lateral (B) views show an obvious lateral condyle fracture and a relatively subtle olecranon fracture. [12], A study of 62 elementary school baseball players (grades 4-6; ages 9-12 yr) for elbow injuries using MRI found positive findings in 26 (41.9%), all confined to the MCL. This motion causes the ulna to fracture and contact the proximal radius, forcing the radial head to become dislocated from the capitellum. The technique is cost and time effective when treating patients with this type of injury. 2007 Jan. 89(1):58-63. (2013) Hand clinics. Most cases of isolated radial head dislocation in children are likely to actually be Monteggia fracture/dislocation with a subtle ulnar bowing fracture. This website also contains material copyrighted by third parties. 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 Middle finger distal interphalangeal (DIP) joint fracture dislocation following reduction of DIP joint, spanning 20-G needle, and soft tissue repair. At the time the article was last revised Craig Hacking had no recorded disclosures. [QxMD MEDLINE Link]. Medial epicondyle avulsion fracture in an 11-year-old girl with an avulsion of part of the left medial epicondyle (A). This humeroradial or radiocapitellar joint permits the radius to flex and extend relative to the humerus and to rotate throughout elbow flexion and extension. The capitellum (along with the remainder of the cartilaginous epiphysis) is medially and posteriorly displaced relative to the metaphysis. Garon MT, Massey P, Chen A, et al. Phalangeal Fractures Treatment & Management: Fractures of the These fractures are Fracture rotation can be difficult to assess radiologically and is best assessed on clinical examination. Silverman FN. WebDiagnosis and Pathology. Imaging of Pediatric Growth Plate Disturbances. Bookshelf Phalanges of the foot WebTransphyseal Fracture of the Distal Humerus. Closed fractures are generally stable, especially when they do not involve the articular surface. Am J Sports Med. Some common finger fractures can be treated conservatively with appropriate reduction and immobilization. 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. Distal phalanges are the most exposed phalanges and are, therefore, fractured more often than other hand fractures. This is sometimes called a tuft fracture Healing: This normally takes approximately 4-6 weeks to heal. The most common fracture seen is a tuft fracture. 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. Anteroposterior (A) and lateral (B) views. 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. Radiographic findings of proximal radius fractures. Please enable scripts and reload this page. On exam, the dislocation was unable to be reduced. 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. In evaluating the proximal ulna in children, the normal olecranon apophysis must not be mistaken for a fracture fragment. Felix S Chew, MD, MBA, MEd is a member of the following medical societies: American Roentgen Ray Society, Association of University Radiologists, International Skeletal Society, Radiological Society of North AmericaDisclosure: Nothing to disclose. The distal interphalangeal joint was swollen and tender with a loss of active movement. Once the fracture has healed, it is very important to follow all therapy instructions to improve motion in the thumb. Disclaimer. The PIP joints are primarily stabilized by the matching articular phalangeal surfaces plus supportive soft tissue structures, including the collateral ligaments and volar plates. 2015 Aug 28. Radiography also helps identify volar fracture of the middle phalanx and other associated injuries. Patients should be informed that these fractures are often complicated by hyperesthesia, pain, and numbness for up to six months following the injury.12. Copyright 1995-2021 by the American Academy of Orthopaedic Surgeons. You may need surgery to treat the thumb fracture, depending on the location of the break, the alignment of the broken bone, and the amount of movement between the fragments. Distal Phalanx Fracture This very common fracture can occur in many different ways to people of all ages. 1974 Jun. Fractures of the coronoid process are infrequent in children, but they may be seen with posterior elbow dislocation. Medial condyle fracture. Often associated with nailbed injuries that would require evaluation and repair 4. Typical supracondylar fracture. Case Report: Locking Plate for Cubitus Varus Correction in a 7-Year-Old Girl With Osteogenesis Imperfecta. In supracondylar fractures with medial displacement of the distal fragment, there is often internal rotation, which results in varus if the fracture is oblique. (B) Subsequent radiograph shows abnormality of the medial condyle and varus deformity from a growth plate injury. Identify direction (dorsal, volar, lateral), Check for neurovascular status and soft tissue injuries (volar plate in dorsal dislocation, central slip in volar dislocation), Volar: Splint in extension if there is an associated central slip, Check for neurovascular status and soft tissue injuries, Obtain postreduction radiographs (soft tissue injuries often impede reduction), Splint and early range of motion for simple dislocations, Splint for two to four weeks followed by range of motion; hyperesthesia, pain, and numbness common for up to six months following injury, Assess for inability to extend at DIP joint, Radiographs show a bony fragment at dorsal surface of the proximal distal phalanx, Splint DIP joint in extension for eight weeks, Assess for inability to flex at the DIP joint, Radiographs show a bony fragment at volar surface of the proximal distal phalanx, Referral recommended (possible flexor digitorum profundus retraction). Elbow dislocation accounts for approximately 5% of elbow injuries in children. On the anteroposterior view (C), the fracture may clearly be seen to extend all of the way across the metaphysis. The distal phalanx is the most commonly fractured bone of the hand. Fat-suppressed T2-weighted coronal MRI shows that the fracture extends through the metaphysis into the epiphysis, although the articular surface remains intact. However, this finding may cause the injury to be confused with a lateral condyle fracture. When no displacement is present, findings indicating a lateral condyle fracture may be subtle. Understanding the developmental anatomy of the pediatric elbow helps ensure that normal ossification centers are not misinterpreted as fracture fragments. Shaw BA, Kasser JR, Emans JB, Rand FF. In addition to the findings in the multiple ossification centers described above, other normal findings may simulate pathology. Radiographic findings that indicate transphyseal fracture rather than dislocation include maintenance of normal radiocapitellar relations and medial displacement of the forearm bones. 1998. 2008 Apr. 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. 25 (3): 527-42, vii-viii. See permissionsforcopyrightquestions and/or permission requests. Anteroposterior (A) and lateral (B) views. 4B, hyperflexion injury with fracture of articular surface of 20% to 50%. Lateral view in a patient with osteogenesis imperfecta who has had bilateral recurrent fractures in the same region. With subtle fractures, the fracture line may be initially seen through only a portion of the metaphysis. The radiographic depiction of lateral condyle fractures depends on the degree of separation at the fracture site. 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. Subtle cortical deformity also may be present medially or laterally, which may be associated with varus or valgus deformity. The history should include mechanism of injury, timing and progression of symptoms, hand dominance, and any previous finger injury. 2017 Mar 20. represent > 50% of all phalangeal fractures and frequently involve the ungual tuft 1. Graham T, Evans P Maschke S. Operative treatment of selected fractures of the childs hand. 1) and a protective splint was placed. Our patients experienced no pin tract infections, nail defects, or sensation issues. Stage II fractures extend through the articular surface, allowing for a small amount of displacement of the distal fragment and olecranon shift. Klatt JB, Aoki SK. (A) Anteroposterior radiograph shows the displaced lateral condyle and cubitus valgus. Diagnostic difficulties stem both from the complex developmental anatomy of the elbow and from significant differences between children and adults in the patterns of injury after elbow trauma. In most patients, the fracture is a Salter-Harris type I injury, passing entirely through the growth plate. Combined lateral condyle and olecranon fractures. 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. Proximal radial fractures in children are frequently associated with other injuries; such injuries most frequently involve the olecranon. Like the metacarpal, the distal and proximal phalanges can fracture near/into a joint or in the shaft of the bone. Leitch KK, Kay RM, Femino JD, Tolo VT, Storer SK, Skaggs DL. The patient saves significant time by undergoing the procedure in the ER as well by avoiding the additional time to be indicated for the procedure, whether urgent or as an outpatient. In some cases, the fracture may extend into the metaphysis, producing a Salter-Harris type II injury. Open Fracture Reduction Complications of proximal radius fractures. Supracondylar fracture. Trochlear deformity occurring after distal humeral fractures: magnetic resonance imaging and its natural progression. 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. Distal phalanx fracture | Radiology Reference Article A variety of treatment modalities exist for distal phalanx fractures Note associated proximal radial metaphyseal fracture. Fracture, Distal Phalanx The elbow should be well visualized in all patients who have an ulnar injury, with or without an associated radial fracture. The ulna articulates with the humerus at the trochlea, which is the grooved and rounded medial articular portion of the distal humerus. The dashed radiocapitellar line is drawn through the radial neck and should pass through the capitellum. Battle J, Carmichael KD. J Trauma. Distal phalanx or tuft fractures: Closed with minimal to no displacement: Inherently stable Often have an associated subungual hematoma that may need evacuated (see Other Procedures ) for pain control Ice for swelling and pain control 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). [QxMD MEDLINE Link]. Weband phalanx fracture consolidation (Fig. {"url":"/signup-modal-props.json?lang=us"}, O'Graphy T, El-Feky M, Qureshi P, et al. F. Thumb fractures 1. 4(1):25-9. 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. Pathologic mallet fracture of distal phalanx enchondroma With some proximal radial fractures, no displacement of the epiphysis occurs; detection of the fracture depends on the metaphyseal component, which may show only subtle abnormal angular deformity, as in the image below. See the Medscape Reference article Salter-Harris Fracture Imaging for more information. Shaw N, Erickson C, Bryant SJ, Ferguson VL, Krebs MD, Hadley-Miller N, Payne KA. Posterolateral elbow dislocation. Medial epicondyle avulsion fracture with entrapment in an older patient. 295(6590):109-10. Supracondylar fractures may be associated with ipsilateral fractures remote from the elbow, most frequently of the distal radius. WebAbstract. Unable to load your collection due to an error, Unable to load your delegates due to an error. Under conscious sedation and digital block, a Seymour-type exposure3 was utilized to achieve reduction. Initial anteroposterior (A) and lateral (B) views show a nondisplaced lateral condyle fracture. 2nd ed. Successful management is dependent on an early and accurate diagnosis of the injury, through clinical and radiologic evaluation. [42] Distinction between lateral condyle fracture and transphyseal fracture is discussed in that section.
