2005 Oct;21(10):1172-6. doi: 10.1016/j.arthro.2005.06.019. The radial head, on the other hand, is a stabilizer to resist valgus stress regardless of the status of the coronoid. J Hand Surg Am. Later, O’Driscoll had classified the coronoid process fracture into more subtypes [7]. c Biceps tendon. Smaller fragments of coronoid tip in children reported to be repaired by lasso-type suture. Biomechanical testing of a novel osteosynthesis plate for the ulnar coronoid process. The elbow is typically immobilized initially in a position of 90 degrees of flexion. From January 2012 to December 2013, six patients (four males, two females) with a mean age of 26.6 years were treated. - Fixation of the Coronoid Process in Elbow Fracture-Dislocations - Optimal screw orientation for fixation of coronoid fractures - Use of Fine-threaded K-wires in the Treatment of … Coronoid fracture accounted for 2.9% of all mandibular fractures (39/1358). By using this website, you agree to our The radial head, on the other hand, is a stabilizer to resist valgus stress regardless of the status of the coronoid. Follow-ups showed that the fractures had healed well, and the average elbow extension was −2° while the average flexion was 140°. NLM According to Regan and Morrey classification [6], coronoid process fracture can be divided into three types including type I tip fracture, type II with fracture of 50% or less of height, and type III with fracture of more than 50% of height. Four patients could extend their elbow completely, while one patient could not fully extend his elbow, with a shortfall of 10°. This operation is more challenging, since it is difficult to accurately guide the Kirschner wire into its ideal position in the fracture fragment. Comminuted fractures and fracture-dislocations are treated with dorsal contoured plate and screw fixation. 2011;93(20):1873–81. The specimens of a pair were then randomized to be fixed with an AP screw in one specimen and a PA screw in the other. d Elbow median neurovascular bundle (brachial artery, median nerve). National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Isolated type IIIA fracture of the coronoid process of ulna. Highly comminuted type 3 fractures pose a significant problem during open reduction and internal fixation (ORIF) and may be better treated with a hinged external fixator. 2003;3(4):199–207. 2014;6(3):191–9. PA screw placement yielded greater strength and stiffness of fixation than did AP placement. Conclusions: O'Driscoll SW, Jupiter JB, Cohen MS, et al. However, arthroscopy can make accurate positioning of the wire and insertion of the screw easier [23]. California Privacy Statement, No problems related to pronation or supination, elbow instability, or complications of blood vessels or nerves were reported. Follow-ups showed that the fractures had healed well, and the average elbow extension was −2° while the average flexion was 140°. From January 2012 to December 2013, six patients (four males, two females) with a mean age of 26.6 years were treated. The entry points to the elbow were marked before inflating the tourniquet to 250 mmHg. Fixation of the coronoid fragment again depends on location and size. Butler DP, Alsousou J, Keys R. Isolated anterolateral fracture of the coronoid process of the ulna: a case report. Fracture of the coronoid process is not uncommon; it seldomly occurs in isolation and is often accompanied by other fractures or ligament damage in the area, leading to elbow instability. Terms and Conditions, The fracture is identified (Fig. Injury. As the coronoid process is deep to the common flexor origin, exposure from medial side is difficult and limited. They often occur in association with elbow dislocations and play an important role in elbow instability. Rausch V, Hackl M, Seybold D, Wegmann K, Müller LP. Exchange rod technology via the elbow front center approach was used for reduction and fixation of fractures of the coronoid process of the ulna. Conclusions: Fixation of a 50% transverse coronoid fracture improves varus and internal rotatory laxity but is unlikely to meaningfully improve valgus or external rotation laxity. Optimal screw orientation for fixation of coronoid fractures. A 0.045 or 0.062 K-wire stabilizes the fracture (Fig. The combination of small fracture fragment comminution and soft tissue stripping may result in insufficient fixation and residual instability. 2012;43(7):989–98. The outpatients were regularly reviewed to assess the overall function of their elbow joint, based on the Mayo Elbow Performance Score (MEPS) scoring system [3], considering factors such as pain (45 points), range of motion (20 points), stability (10 points), daily function (25 points), and so on, with ≥90 points scored as A, 75–89 points scored as B, 60–74 points scored as C, and ≤60 points scored as D. X-ray examinations conducted at the time of surgery showed that all fractures were anatomically reduced.  |  7-8)and reduced with a sharp tenaculum. Regan W, Morrey B.
