coronoid fracture fixation

fixation of the coronoid fracture leads to fewer complications and improved outcomes compared with screw or suture anchor fixation techniques. Cohen MS. Fractures of the coronoid process. One patient with Regan and Morrey type II fracture had a large fracture fragment and required two cannulated screws for fixation. From January 2012 to December 2013, six patients (four males, two females) with a mean age of 26.6 years were treated. J Shoulder Elbow Surg. Anat Rec A Discov Mol Cell Evol Biol. Privacy A 3.9 cannulated screw was then used to secure the coronoid onto the proximal ulna. For these reasons, our results may not reflect the whole advantages of this arthroscopic technique. Anterior approach for fixation of isolated type III coronoid process fracture. J Bone Joint Surg Am. Arthroscopic reduction and fixation of coronoid fractures with an exchange rod—a new technique. Sanchez-Sotelo J, O'Driscoll SW, Morrey BF. With the index finger still in situ, a blunt exchange rod measuring about 3 mm in diameter was introduced along the pulp of the index finger, through the anterior capsule. A case report and brief review of literature. Optimal screw orientation for fixation of coronoid fractures. California Privacy Statement, Google ScholarÂ. According to the Regan and Morrey fracture classification and O’Driscoll’s classification, two and four patients were classified as type I and type II and as having tip fracture (O’Driscoll type I) and anteromedial fracture (O’Driscoll type II), respectively. Dr. Goetz highlights his technique for approach and fixation of the coronoid process. After fixation, the extension and flexion of the joint was checked to assess the stability of fixation, particularly when it was under the valgus stress. a–c CT scan of a 32-year-old male patient shows fracture of the ulnar coronoid process (Regan and Morrey type II). CT and MR imaging aimed to check the degree of instability for posterolateral and posteromedial rotation.

Almost all the surgical techniques noted above using open surgeries which typically require a fairly large incision and the small fracture fragment may slide into the posterior compartment of the elbow. Later, O’Driscoll had classified the coronoid process fracture into more subtypes [7]. Wolschrijn CF, Weijs WA. PubMed  doi: 10.1016/j.jhsa.2016.11.003. Moreover, it protects the surrounding soft tissue, shows good stability of the components, and allows early rehabilitation exercises. 2016;25(8):1268–73. Conclusions: Article  Rausch V, Hackl M, Seybold D, Wegmann K, Müller LP. The low incidence of this specific fracture pattern compelled us to study only a small number of cases. The tourniquet was released. Arthroscopic reduction and fixation of coronoid fractures with an exchange rod-a new technique. The role of the coronoid process in elbow stability. Google ScholarÂ. In total, six patients (four males and two females) with an average age of 26.6 (ranged from 19 to 34) years were recruited; two patients had a fracture of the left ulna while four patients had a fracture of the right ulna. Accurate anesthetization of the arm was ensured. 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. Suture versus screw fixation of displaced tibial eminence fractures: a biomechanical comparison. Oper Orthop Traumatol. Arthroscopically assisted coronoid fracture fixation: a preliminary report. Instr Course Lect. Correspondence to All of our results showed fractures were healing well, and the elbows were in stable condition. KOY and DPW carried out this project and guided the research. Park SM, Lee JS, Jung JY, et al. According to O’Driscoll’s [13] typing method, two patients were classified as having tip fracture (O’Driscoll type I), and four patients were classified as having anteromedial fracture (O’Driscoll type II). 1991;73(3):440–6. Therefore, prompt anatomical reduction is recommended. However, our group of patients had sufficiently large fragments to allow screw fixation. [Study advancement of anatomy and biomechanics of posterior three type screw fixation techniques of axial]. This study described six patients in whom the exchange rod arthroscopic technique was effectively used for the reduction and fixation of fractures of the coronoid process of the ulna. Coronoid fracture accounted for 2.9% of all mandibular fractures (39/1358). Eur J Orthop Surg Traumatol. JYX and LQP collected the research data and made the statistical analysis. 2011;20(2):e1–4. 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). Transverse fractures (Mayo type I) of the coronoid tip … The radial head, on the other hand, is a stabilizer to resist valgus stress regardless of the status of the coronoid. J Shoulder Elbow Surg.

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. Minimal invasive surgery for coronoid fracture: technical note. Fixation of the coronoid fragment again depends on location and size. The fracture is identified (Fig. Minimal invasive percutaneous plate osteosynthesis for complex monteggia fracture with type III coronoid process fracture. Coronoid fracture is fixed first through the lateral approach followed by radial head and ligament repair. Kiene J, Bogun J, Brockhaus N, et al. The left and right ulnas were involved in two and four patients, respectively. Closkey RF, Goode JR, Kirschenbaum D, et al. 2002;122(3):184–5. Posterolateral rotatory instability of the elbow.

Reconstruction for elbow instability caused by congenital aplasia of the ulnar coronoid process—a case report.  |  Moreover, it may hinder the blood supply of the fracture fragments. 2005;14(1):60–4. Large anteromedial facet fractures can be secured with precontoured or T-plates in a buttress fashion [8, 12]. Damage to the coronoid process in addition to other elbow structures may complicate treatment. To the editor: On "Optimal screw orientation for fixation of coronoid fractures". 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. 2005 Oct;21(10):1172-6. doi: 10.1016/j.arthro.2005.06.019. Doornberg JN, Ring D. Coronoid fracture patterns. 2017 Jan;42(1):e11-e14. Under arthroscopy, the external rotation shift and the width of the brachial, ulnar, or medial artery or the subluxation of the humeral bone and caput radii were tested. The elbow extension in all five patients averaged −2° (range, −10° to 0°), while the average flexion was 140° (range, 135° to 145°). 2014;6(3):191–9. KOY, DPW, HFL, HL, JX, and WZF contributed to the follow-up of the patients and wrote the manuscript. 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°. Medial oblique compression fracture of the coronoid process of the ulna. We therefore investigated the feasibility of arthroscopic reduction and internal fixation (ARIF) with anterior capsule repair for management of Types I and II coronoid fractures in cases of isolated coronoid fractures with demonstrable instability on conventional radiographs, MRI, or CT (Fig. O'Driscoll SW, Bell DF, Morrey BF. Bong MR, Romero A, Kubiak E, Iesaka K, Heywood CS, Kummer F, Rosen J, Jazrawi L. Arthroscopy. HHS No blood vessel or nerve damage was observed during the 1-year follow-up period. Part of Knee Surg Sports Traumatol Arthrosc. Calcaneal Fracture ORIF with Lateral Approach, Plate Fixation, and Locking Screws RETIRE Transtibial Below the Knee Amputation (BKA) Coronoid Fractures Pathway Updated: 10/4/2016 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. Physical therapy following coronoid fracture fixation is usually surgeon dependent and is variable. Methods: A retrospective chart review performed at three tertiary care centers identified forty consecutive patients treated for terrible triad injuries of the elbow with a minimum follow-up of eighteen months (mean, twenty-four months; range, … Follow-ups showed that the fractures had healed well, and the average elbow extension was −2° while the average flexion was 140°. Biggest challenge in fixation of coronoid fracture is adequate surgical exposure. The coronoid fracture in our case was classified as a type I fracture, which is a transverse fracture of the coronoid tip. All authors read and approved the final manuscript. Even though type I fractures can usually be treated non-surgically, the optimal treatment for type I coronoid process fractures remains controversial [19]. USA.gov. 2004;20(4):443–53. At this point, the anterior capsule was pushed with the index finger and visualized through the arthroscope. PA screw placement yielded greater strength and stiffness of fixation than did AP placement. J Orthop Surg Res 12, 9 (2017). a Radial nerve. 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. Epub 2018 Apr 2. COVID-19 is an emerging, rapidly evolving situation. Han SH, Yoon HK, Rhee SY, et al. NLM Clipboard, Search History, and several other advanced features are temporarily unavailable. Arthroscopy using an exchange rod can provide excellent visual exposure of the fractured joints, without the need for a large incision during the anatomical repair. The fracture site was then refreshed by removing any tissue that prevented a good reduction and ultimate fixation.  |  Fixation of the coronoid process in elbow fracture-dislocations. doi: 10.2106/JBJS.ST.M.00076. Arthroscopy enables perfect visualization to allow anatomical repair. The ligament injuries associated with a small coronoid fracture may play a more important role in elbow instability than the fracture itself. Fixation of the coronoid fragment again depends on location and size. Arrigoni P, Cucchi D, Guerra E, Luceri F, Nicoletti S, Menon A, Randelli P. Knee Surg Sports Traumatol Arthrosc. O'Driscoll SW, Jupiter JB, Cohen MS, et al. The lateral cutaneous nerve of the forearm was carefully protected and tracted laterally with the skin and subcutaneous tissue. The coronoid plays a pivotal role as an anterior buttress, yet the optimal management of the coronoid fracture remains unknown. 2009;23(4):277–80. Since the elbow remained unstable throughout the range of … On the basis of our preliminary study, we speculate that fractures of the coronoid process of the ulna that do not require obvious open reduction surgery can be treated by arthroscopic reduction and fixation by using the exchange rod technology, which provides excellent visualization and allows a good anatomical repair without extensive dissection of soft tissue. In fact, when these kinds of fractures show elbow joint instability, internal fixation is preferred [17]. A surgical strategy based on O’Driscoll classification and ligament injury.  |  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]. Some of its fractures were often combined with injury of bone and ligament. The anterior area of the elbow is rich in blood vessels and nerves; however, the area that is close to the outer flank of the biceps tendon is relatively safe (Fig. 6). In cases where the fracture fragment is too small for screw fixation, some studies have reported that the use of cerclage suture fixation has achieved good results [21]. 2008;466(12):3147–52. 2003;52:113–34. For some fractures (type II) fixation with a 2.7-mm screw is adequate (Figs. 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’scapsular attachment. 2019 Jan;27(1):314-318. doi: 10.1007/s00167-018-4926-2. Together with the fact that it is clinically easier to insert and remove screw from the posterior ulna, these data indicate that optimal screw orientation for fixation of coronoid tip fracture is posterior to anterior direction. This study was approved by the Medical Ethics Committee of Shenzhen University, which was performed in accordance with the ethical standards of the 1964 Declaration of Helsinki as revised in 2000.

Anatomy of the elbow with a median approach using the Kirschner wire. DPW, KOY, and WL performed the surgery for this study. Fractures of the coronoid process of the ulna. No problems related to pronation or supination, elbow instability, or complications of blood vessels or nerves were reported. Further, MR imaging could assess the integrity of the medial or lateral collateral ligament. 2009 Sep;23(8):612-3; author reply 613. doi: 10.1097/BOT.0b013e3181b65a08. The patients gave their oral and written informed consent to the publication of their anonymous and clustered data and anonymous pictures. J Shoulder Elbow Surg. PubMed Central  The brachial artery and median nerve lie on the inner flank of the biceps tendon, protected by the muscle tendon; the lateral cutaneous nerve to the forearm, cephalic vein, radial nerve, and radial collateral artery are on its outer flank.

The average age in this study group was 38.7 years (range 22–58 years). 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). 2013;23(4):395–405. Subsequently, the arthroscopy was introduced via the proximal, anteromedial, and lateral approaches, and the soft tissue around the fracture block was cleared, separating it from the outer tissues. A transverse osteotomy at the midpoint of the coronoid height was created to simulate a Regan–Morrey type II coronoid fracture. 2012;43(7):989–98. 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. Vishwanath J, Agarwal A, Mehtani A, et al. Sukegawa K, Suzuki T, Ogawa Y, et al. All fractures were consequences of indirect violence. In awake as well as anesthetized patients, humero-ulnar instability between 25° elbow extension and full extension was observed. This enables the insertion of the screw vertical to the fracture line, which facilitates anatomical reduction and firm fixation. We performed a biomechanical study using 10 pairs of fresh-frozen cadaveric elbows. It has been believed that only type III fractures require open reduction and internal fixation to improve elbow instability [9]. 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]. 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. This paper reports a method of coronoid process fracture fixation using suture anchors. 1, 2, 3 The treatment of fracture-dislocations requires attention to the coronoid, radial head, and lateral collateral ligament.
