How should anteromedial coronoid facet fracture be managed? Article  The elbow extension in all five patients averaged −2° (range, −10° to 0°), while the average flexion was 140° (range, 135° to 145°). All five patients showed an MEPS score of A. a X-ray of a 32-year-old male patient shows fracture of the ulnar coronoid process (Regan and Morrey type II). 2014;6(3):191–9. Later, O’Driscoll had classified the coronoid process fracture into more subtypes [7]. Daping Wang. For some fractures (type II) fixation with a 2.7-mm screw is adequate (Figs. Transverse fractures (Mayo type I) of the coronoid tip …  |  No blood vessel or nerve damage was observed during the 1-year follow-up period. It is believed that these fractures generally require open reduction and internal fixation in order to avoid recurrent elbow instability. Exchange rod technology via the elbow front center approach was used for reduction and fixation of fractures of the coronoid process of the ulna. The elbow is typically immobilized initially in a position of 90 degrees of flexion. Article  Even though this was not a long-term follow-up study, our results showed arthroscopy with an exchange rod can be an efficient method in treating the coronoid process fractures. Privacy The ulnar coronoid process plays a central role in maintaining elbow stability. The fingertip was used to separate and gradually reach the anterior capsule of the elbow joint. Subtype I fracture was usually associated with posterior elbow dislocation injury, whereas subtype II and subtype III fractures were associated with varus subluxation. A Kirschner wire of 1.5 mm diameter was then passed through this cannula into the joint. J Bone Joint Surg Am. 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. 7-10 and 7-11). Some of its fractures were often combined with injury of bone and ligament. Manage cookies/Do not sell my data we use in the preference centre. J Orthop Trauma. The patients received a thorough explanation of this study, and their oral and written informed consent was obtained in this study. Further, MR imaging could assess the integrity of the medial or lateral collateral ligament. Biggest challenge in fixation of coronoid fracture is adequate surgical exposure. All surgeries were finished in 90 min, with the average bleeding amount no more than 20 ml. Different surgical techniques have been described: suture lasso, screws, plates, and tension band wiring with steel wire (an original internal fixation technique by tension band wiring with steel wire in fractures of the coronoid process). Meanwhile, more prospective research regarding the comparison of arthroscopic technique and other open surgical techniques need to be performed. Congruent stability of the elbow joint and anatomical fracture healing remain the primary goals of treatment [6, 7, 15]. fixation of the coronoid fracture leads to fewer complications and improved outcomes compared with screw or suture anchor fixation techniques. Its fracture is not uncommon; it seldom occurs in isolation and is often accompanied by other fractures and/or ligament damage, consequently leading to elbow instability, which makes it a difficult fracture to handle [5]. 2019. The radial head, on the other hand, is a stabilizer to resist valgus stress regardless of the status of the coronoid. Desloges W, Athwal GS, Elkinson I, King GJW, Faber KJ. 6 Furthermore, the osteochondral flap fracture of the coronoid is a very rare fracture in pediatric patients. © 2020 BioMed Central Ltd unless otherwise stated. KOY and DPW carried out this project and guided the research. 2016;87(1):85–6. No problems related to pronation or supination, elbow instability, or complications of blood vessels or nerves were reported. Insertion torque, load to failure, and stiffness were measured under axial load with a material testing machine. Oper Orthop Traumatol. Accurate anesthetization of the arm was ensured. 2015;24(1):74–82. The goal of treatment is to obtain a stable, pain-free, and functional elbow. Injury. Insertion torque, load to failure, and stiffness were measured under axial load with a material testing machine. Minimal invasive percutaneous plate osteosynthesis for complex monteggia fracture with type III coronoid process fracture. Larger fragments can be fixed by screws as necessary with cannulated or non-cannulated screws. Ouyang, K., Wang, D., Lu, W. et al. Some studies have reported that the Kirschner wire is introduced from the rear of the elbow, and, similarly, the screw is introduced into the hollow nail to fix the fractures [22]. 2004;20(4):443–53. 2019 Jan;27(1):314-318. doi: 10.1007/s00167-018-4926-2. Vishwanath J, Agarwal A, Mehtani A, et al. Biomechanical testing of a novel osteosynthesis plate for the ulnar coronoid process. DPW, KOY, and WL performed the surgery for this study. J Shoulder Elbow Surg. 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. The ulnar coronoid process plays a central role in stabilizing the elbow joint [7, 13, 15–18]. Acta Orthop. The mean stiffness was 106 N/mm with PA screws and 76 N/mm with AP screws (P < 0.05). Anterior approach for fixation of isolated type III coronoid process fracture. Dr. Goetz highlights his technique for approach and fixation of the coronoid process. Fixation of the coronoid process in elbow fracture-dislocations. PubMed  In fact, when these kinds of fractures show elbow joint instability, internal fixation is preferred [17]. Treatment should be begun as early as possible and be associated with early rehabilitation and short lasting immobilization. Clin Orthop Relat Res. Arthroscopically assisted coronoid fracture fixation: a preliminary report. Using arthroscopy can help obtain intra-articular control of fracture reduction which enables perfect visualization to prevent damage to the capsules and protect the blood supply. All patients suffered from ipsilateral subluxation of the elbow without associated radial fracture. The dataset supporting the conclusions of this article is available at our institution. 2004;278(2):514–9. However, our group of patients had sufficiently large fragments to allow screw fixation. 2017 Jan;42(1):e11-e14. Coronoid process fractures of the ulna are difficult to treat, and are associated with stiffness, recurrent instability, and pain. Results: The index finger was used to feel and separate the blood vessels, nerves, muscle, and other tissues. A 0.045 or 0.062 K-wire stabilizes the fracture (Fig. Pugh DM, Wild LM, Schemitsch EH, et al. 2003;52:113–34. The role of the coronoid process in elbow stability. This site needs JavaScript to work properly. They are easily located and are pulled outside for protection. The coronoid fracture in our case was classified as a type I fracture, which is a transverse fracture of the coronoid tip. Regan W, Morrey B. Fractures of the coronoid process of the ulna. After blunt dissection with the index finger, the exchange rod technique is used to further reduce the risk of neurovascular injury. Fractures of the coronoid process of the ulna. Regan and Morrey [6] classified fractures based on the fragment size, with type III fracture accounting for more than 50% of the coronoid process fractures. 2011;93(20):1873–81. Intra- and postoperative X-ray examination showed that the fractures were satisfactorily fixed and that the screw and fracture line were vertical to each other. Minimal invasive surgery for coronoid fracture: technical note. Smaller fractures associated with the “terrible triad” or varus posteromedial instability can be stabilized by “lasso-type” sutures through proximal ulnar drill holes or suture anchors both incorporating the fragment’s capsular attachment. Clipboard, Search History, and several other advanced features are temporarily unavailable. Kiene J, Bogun J, Brockhaus N, et al. As is known, type III fractures can cause severe elbow instability; moreover, based on the extent of the bone injury rather than ligament injury, the surgeons usually opt for the safer and more reliable open fixation [7, 15, 20]. Arthroscopy enables perfect visualization to allow anatomical repair. J Hand Surg Am.

Injury. No neurovascular damage after creation of an accessory anteromedial portal for arthroscopic reduction and fixation of coronoid fractures. 2002;122(3):184–5. Suture versus screw fixation of displaced tibial eminence fractures: a biomechanical comparison. J Shoulder Elbow Surg. No problems related to pronation or supination, elbow instability, or complications of blood vessels or nerves were reported. Sanchez-Sotelo J, O'Driscoll SW, Morrey BF. 2003;3(4):199–207. After treatment, the elbow was kept immobilized in a plaster for 2–3 days, followed by encouraging gentle active movements, avoiding violent massage to prevent the occurrence of myositis ossificans. O'Driscoll SW, Bell DF, Morrey BF. With the fracture accurately reduced, the wire was inserted vertical to the posterior cortex of the bone fragment. a–h Exchange rod arthroscopic techniques for the reduction and fixation of fracture of the ulnar coronoid process: clean fracture surface, fracture reduction (a, b); exchange rod technique for midline approach (c, d); Kirschner wire pierced vertical to the bone (e, f); and screwed into the hollow screw (g, h). Cookies policy. Intra- and postoperative X-ray examination showed that the fractures were satisfactorily fixed and that the screw and fracture line were vertical to each other. The patient was laid in a supine position on the operating table, with the upper limb, the elbow, and the upper limb flexed forward to 90° and the forearm flexed to nearly 30°. 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. Objective: PubMed  Hand Clin. 2018 Sep;97(36):e12041. Hence, treatment of coronoid process fractures are challenging for surgeons. The lateral cutaneous nerves to the forearm and cephalic vein are comparatively shallow, so the incision is made in the skin alone, and dissected carefully. Plate fixation through an anterior approach for coronoid process fractures: A retrospective case series and a literature review. The authors declare that they have no competing interests. Comminuted fractures and fracture-dislocations are treated with dorsal contoured plate and screw fixation. doi: 10.2106/JBJS.ST.M.00076.
