Abstract
OBJECTIVE The study aims to explain whether or not minimal invasive surgery (MIS) would be feasible in elbow fracture-dislocation with coronoid process fracture. METHODS At Taipei Veterans General Hospital, patients who had elbow dislocations with coronoid process fractures underwent a single surgeon's MIS techniques which included the fluoroscopy-guided ulnar anteromedial (FGUAM) approach in the stage of reducing the coronoid process. When there is a proximal ulnar fracture, the posterior incision should be necessary, followed by the incision over the lateral or medial elbow for treating radial fractures or ligament injuries. RESULTS The Flow Diagram for approach recommendation was established on the basis of defining MIS as that which does not include cross-plane dissection. The importance of anterior rigid fixation for the coronoid process was also emphasized. CONCLUSIONS MIS can be achieved by multiple limited surgical incisions. Although the posterior extensile approach is necessary in situations of ulnar metaphysis or ligament avulsion fracture, the FGUAM approach decreases the cross-plane dissection.

Zhou SC, Jin SY, Wang QY, Ren GK, Peng CG, Wang YB, Wu DK. Highly extensile approach for comminuted ulna coronoid process fractures with mini-plate fixation: a case series of 31 patients. BMC Musculoskelet Disord 2024; 25:522. [PMID: 38970051 PMCID: PMC11225124 DOI: 10.1186/s12891-024-07637-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Accepted: 06/27/2024] [Indexed: 07/07/2024] Open
Abstract
BACKGROUND For the treatment of coronoid process fractures, medial, lateral, anterior, anteromedial, and posterior approaches have been increasingly reported; however, there is no general consensus on the method of fixation of coronal fractures. Here, we present a highly-extensile minimally invasive approach to treat coronoid process fractures using a mini-plate that can achieve anatomic reduction, stable fixation, and anterior capsular repair. Further, the study aimed to determine the complication rate of the anterior minimally invasive approach and to evaluate functional and clinical patient-reported outcomes during follow-up. METHODS Thirty-one patients diagnosed with coronoid fractures accompanied with a "terrible triad" or posteromedial rotational instability between April 2012 and October 2018 were included in the analysis. Anatomical reduction and mini-plate fixation of coronoid fractures were performed using an anterior minimally invasive approach. Patient-reported outcomes were evaluated using the Mayo Elbow Performance Index (MEPI) score, range of motion (ROM), and the visual analog score (VAS). The time of fracture healing and complications were recorded. RESULTS The mean follow-up time was 26.7 months (range, 14-60 months). The average time to radiological union was 3.6 ± 1.3 months. During the follow-up period, the average elbow extension was 6.8 ± 2.9° while the average flexion was 129.6 ± 4.6°. According to Morrey's criteria, 26 (81%) elbows achieved a normal desired ROM. At the last follow-up, the mean MEPI score was 98 ± 3.3 points. There were no instances of elbow instability, elbow joint stiffness, subluxation or dislocation, infection, blood vessel complications, or nerve palsy. Overall, 10 elbows (31%) experienced heterotopic ossification. CONCLUSION An anterior minimally invasive approach allows satisfactory fixation of coronoid fractures while reducing incision complications due to over-dissection of soft tissue injuries. In addition, this incision does not compromise the soft tissue stability of the elbow joint and allows the patient a more rapid return to rehabilitation exercises.

[PMID: 36584867 DOI: 10.1016/j.jse.2022.11.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 11/15/2022] [Accepted: 11/20/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND The role of the coronoid process in elbow instability has been established. When necessary, coronoid fixation can be challenging. Placing fixation perpendicular to the fracture requires achieving a trajectory as close as possible to the midline axis of the proximal ulna, either from anterior to posterior or vice versa. The aim of this study was to determine whether coronoid exposure-and the ability to place fixation from anterior to posterior-is improved via a lateral extensor-splitting approach with forearm supination, that is, the "spin move," with progressive stages of lateral elbow instability. METHODS The lateral extensor-splitting approach was performed on 9 cadaveric upper extremities. A 0.157-mm (0.062-inch) wire was drilled perpendicularly into the lateral aspect of the humerus just proximal to the lateral epicondyle. A second wire was drilled into the tip of the coronoid, aiming for a drill trajectory as close as possible to the midline axis. The angle between the 2 wires was measured as the initial angle. Three stages of progressive lateral elbow instability were produced by sequential release of the lateral ulnar collateral ligament (LUCL), common extensor origin (CEO), and posterior capsule. At each stage, the spin move was performed and the angle between the 2 wires was measured. The difference between this angle and the initial angle was calculated, with the average value reported as the Δ angle for each stage. The average difference between each stage and the next stage was reported. RESULTS The spin move resulted in Δ angles of 10.3° with the LUCL released, 20° with the CEO released, and 29.1° with the posterior capsule released. Progressing from LUCL release to CEO release to posterior capsule release, the Δ angle between the K-wires increased an average of 9.6° from the LUCL stage to the CEO stage and 9.1° from the CEO stage to the posterior capsule stage. CONCLUSION The spin move is a simple maneuver that can improve exposure of the coronoid process regardless of the degree of elbow instability. This may facilitate a more perpendicular screw, bone tunnel, or suture anchor trajectory via the lateral approach, reducing the need for posterior-to-anterior fixation. The improved exposure is inferred from the differences in the K-wire angles with and without the spin move. This study has also quantified the change in coronoid exposure using the angles of the wires with progressive release of the LUCL, CEO, and posterior capsule. If necessary, releasing the CEO or posterior capsule with eventual repair may allow improved coronoid fixation from the lateral approach.

Abstract
OBJECTIVE This study is aimed to investigate the clinical outcomes of a novel SSPS for fixation of the comminuted coronoid fracture. METHODS A retrospective study was carried out in the patients with comminuted fractures of the coronoid treated by SPSS fixation between January 2014 and December 2018. A total of 17 patients (17 sides) was included in our study, including 11 male and six female, with a mean age range from 18 to 60. All cases started to functional rehabilitation immediately after the operation. Clinical outcomes were evaluated both radiographically and functionally at the follow-up visit, including the elbow instability, range of motion and Mayo elbow performance score (MEPS). RESULTS According to the O'Driscoll classification system, there was two side of type 1.2, two of type 2.1, four of type 2.2, three of type 2.3, two of 3.1 and four of type 3.2. The surgery was carried out by Kocher and anteromedial approach in 12 patients, posterior and anteromedial approach in four, anterior approach in one. The average operation time and intraoperative blood loss was 129.41±43.87 min and 115.29±104.65 ml. The median follow-up time was 9 months (range, 6 to 15 months). The mean flexion, extension, pronation and supination motion was 138.76±8.67 degrees, 20.00±13.58, 82.94±5.32and 74.12±14.39 respectively at final follow up. The mean MEPS score was 89.76±8.46, including 11 excellent, 3 good and 3 fair result. The mean VAS score was 1.94±0.97. The mean union time of coronoid fractures was 2.77±0.31 months according to the established standard of healing. There were no significant differences in clinical outcomes among groups according to the O'Driscoll classification (P > .05) and ligament repair strategy (P > .05). No patient underwent instability or dislocation of the elbow during follow up. There were two cases with mild ulnar nerve symptoms which recovered totally at follow up. Meanwhile, there were three cases with heterotopic ossification of the elbow. CONCLUSION Our findings demonstrated that the SSPS can provide a reliable fixation for the comminuted coronoid fracture with satisfactory clinical outcomes.

Abstract
The ulnar coronoid process plays a key role in maintaining elbow stability; however, there is no gold standard treatment for ulnar coronoid process fractures. We present a novel surgical technique, arthroscopic reduction and bent K-wire fixation, for type II and III coronoid process fractures according to the O’Driscoll classification. Five patients were treated and retrospectively reviewed between January 2016 and December 2019. All the surgeries were performed by a single surgeon. We evaluated clinical outcomes by evaluating a range of motion, disability of arm, shoulder, and hand (DASH) score, Mayo Elbow Performance score (MEPS), and radiographic images. Intraoperative and postoperative radiographs showed that the fractures healed well and were satisfactorily fixed. The average elbow extension/flexion was −3/130, with an average DASH score of 2.42 and MEPS of 97. Coronoid process fractures can be treated successfully with arthroscopic reduction and fixation of bent K-wire, which allows more rigid fixation and early functional exercise, resulting in good outcomes without special tools.

One incision-two windows approach for fixation of multifragmentary coronoid process fracture of the ulna: A case report. Trauma Case Rep 2022; 40:100655. [PMID: 35665199 PMCID: PMC9160398 DOI: 10.1016/j.tcr.2022.100655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/21/2022] [Indexed: 11/24/2022] Open
Abstract
Since the range of access of each surgical approach around the elbow has limitations, it is difficult to treat all types of fractures using only one approach. In the case reported herein, anterior and medial fragments of the comminuted ulnar coronoid process fracture were treated by preparing two access routes through one skin incision and effectively performing the buttress plating of each fragment. The subject was a 27-year-old female who sustained a fracture of the coronoid process of the right ulna by falling during snowboarding. Computed tomography showed the concurrence of a type 2 subtype III and type 3 subtype I ulnar coronoid process fracture according to the O'Driscoll classification. The coronoid process was split into 3 parts: a fragment consisting of the anteromedial facet and upper half of the sublime tubercle (fragment 1), a central fragment including the tip (fragment 2), and a fragment extending from the radial side of the tip to the base of the coronoid process (fragment 3). A 12-cm-long skin incision was made on the anteromedial side of the elbow joint. The region of the anteromedial facet and sublime tubercle was reached by passage between the palmaris longus/flexor digitorum superficialis and humeral head of flexor carpi ulnaris using the over-the-top approach. Fragment 1 was fixed with a buttress plate. Using the anterior approach, the brachialis was then longitudinally split through by passage between the biceps and neurovascular bundle, fragments 2 and 3 were fixed together with a buttress plate. The “one incision-two windows” approach, which provides two approaches (the over-the-top window and the anterior window) by a single skin incision, was implemented for a multifragmentary ulnar coronoid process fracture. This approach is considered to offer access from the front to each of the anterior and medial fragments and permits appropriate buttress plate fixation.

Abstract
Background Existing approaches for treating elbow fractures include lateral, medial, anterior and posterior approaches, though the anterior approach is often not chosen by surgeons to avoid damage to important nerves and blood vessels. However, the anterior approach has unique advantages. The purpose of this study was to report outcomes of 38 patients with coronal plane elbow fractures treated through the anterior approach. Methods We retrospectively analyzed 38 cases of coronal plane elbow fracture treated through an anterior approach at our institution between March 2015 and July 2019. The length of the surgical incision, operation time, and postoperative complications were recorded. The range of flexion, extension, and rotation of the affected elbow and the healthy elbow were collected at follow-up. Functional outcomes were evaluated using the Mayo Elbow Function Score (MEPS). Results All 38 patients were followed up for a mean of 21.26 months (range 12–36 months). Intraoperatively, the mean surgical incision length was 8 ± 2 cm and the mean operative time was 123 ± 59 min. At the final follow-up, solid osseous union was confirmed for all coronal plane elbow fractures. The mean elbow flexion arc was 129 ± 7°, and the extension arc was 9 ± 6°. The mean pronation arc was 83 ± 3°, and the supination arc was 80 ± 3°. The mean MEPS was 90 ± 8 points, with 18 excellent cases and 20 cases of excellent and good results, respectively. In 31 cases, there was no significant difference in elbow extension, flexion, or pronation between the single-fracture and healthy elbows (P > 0.05), though the arc of supination was slightly worse than that of the healthy elbow (P < 0.05). VAS pain scores before the operation, at three months after the operation, and during follow-up were compared, and pain was significantly reduced after treatment (P < 0.05). Two patients experienced transient postoperative median nerve paralysis, from which they recovered within three months. One patient had mild heterotopic ossification and was not treated because it did not affect the function of the elbow joint. All patients returned to work and were satisfied with the treatment. Conclusion The anterior approach has the benefits of simplicity, safety, minimal invasiveness, excellent exposure, and satisfactory prognosis for coronal plane elbow fracture.

Abstract
BACKGROUND The optimal approach for the fixation of coronoid process fractures is unknown. We present the advantages and the clinical effect of the pronator teres and the flexor carpi radialis interval approach for the treatment of ulna coronoid process fractures. METHODS The patients, who had operative treatment of closed ulna coronoid process fracture by the pronator teres and the flexor carpi radialis interval approach between January 2011 to December 2016, were studied retrospectively. Seventeen consecutive patients had received surgical fixation by screws or a mini-plate through the above approach, of whom were 16 males and one female with an average age of 36.7 years (range, 21-58 years). There were 11 cases of type II and 6 cases of type III according to the O'Driscoll classification, of which, 6 patients had combined elbow dislocation, 2 patients showed elbow instability after fixation, and one had another incision to repair the lateral collateral ligament, and received a hinged external fixator. The other patient only received a hinged external fixator for 4 weeks. Mayo Elbow Performance Score (MEPS) was used to assess the function of elbow for each patient at the final follow-up. RESULTS Mean follow-up was 28.7 months (range, 24-38 months). Fracture union was achieved in each patient; the average time to radiologic union was 14.2 weeks (range, 12-16 weeks). At the final follow-up, the elbow extension degree of the affected side was (3.88±2.96°), reaching 98.1% of the normal side, and the flexion degree was (131.59±4.93°), reaching 98.16% of the normal side. The forearm pronation was (82.94±3.86°), reaching 94.31% of the normal side, and the supination activity was (82.12±3.82°), reaching 93% of the normal side. According to the MEPS, the functional recovery of the injured arm was assessed as excellent in 16 cases, and good in one. None of the patients showed any neurovascular or deep infections and no heterotopic ossification was found. CONCLUSIONS The pronator teres and the flexor carpi radialis interval approach has the advantages of simplicity, safety, minimal invasion, excellent exposure, and good postoperative function recovery for ulna coronoid process fracture.

Abstract
Terrible triad of the elbow associates posterior dislocation, radial head fracture and coronoid process fracture. It is a complex trauma, associating severe bone and ligament lesions, with high more-or-less long-term risk of residual instability, stiffness, pain and osteoarthritis. During the last 20 years, pathologic, biomechanical and clinical knowledge has greatly progressed. Prevention of these severe complications requires initial understanding of the lesion mechanism and precise analysis of all lesions. Surgery aims to restore perfect stability by sequential anatomic repair, enabling early mobilization to prevent onset of stiffness. The aims of the present paper were to summarize the anatomic and pathophysiological bases, highlight the crucial importance of the humeroradial column and lateral collateral ligament, and to determine the importance of the coronoid process. Some aspects of treatment are controversial: systematic medial collateral ligament repair, or use of an articulated external fixator. Finally, we propose a simple algorithm to guide repair.

Abstract
OBJECTIVE To investigate the effectiveness of a modified anteromedial approach in the treatment of ulnar coronoid process fracture. METHODS Between February 2017 and July 2018, 15 patients with ulna coronoid process fracture were reviewed. There were 9 males and 6 females, with an average age of 42.3 years (range, 24-60 years). The causes of injury included falling in 10 cases and traffic accidents in 5 cases, all cases were closed injury. According to the O'Driscoll classification, there were 4 cases of type Ⅰ, 6 cases of type Ⅱ, and 5 cases of type Ⅲ. The time from injury to operation was 2-8 days (mean, 3.7 days). All fractures were treated via a modified anteromedial approach between the pronator teres and the flexor carpi radialis plus with partial incision of flexor tendon aponeurosis. The fracture healing, muscle strength of forearm, postoperative complications were observed. At last follow-up, the elbow mobility were measured, the function of elbow was evaluated by Mayo elbow performance score (MEPS). RESULTS All cases were followed up 10-18 months (mean, 13.3 months). Fracture union was achieved in all patients with a mean time of 10 weeks (range, 8-14 weeks). No obvious decrease of hand grip strength, nerve injury, and infection occurred. One patient had slight heterotopic ossification without special treatment. At last follow-up, all patients had stable elbows with good flexion-extension and varus-valgus stability, the mean flexion was 123.3° (range, 100°-140°), mean extension loss compared with that before operation was 6.7° (range, 0°-20°), mean pronation was 76.0° (range, 60°-85°), and mean supination was 75.8° (range, 55°-90°). The MEPS score was 65-100 (mean, 90.3) with the result of excellent in 10 cases, good in 4 cases, and fair in 1 case. CONCLUSION The treatment of ulnar coronoid process fracture via the modified anteromedial approach provides excellent exposure, minimal invasion, fewer complications, and satisfactory prognosis, which is conducive to elbow joint function recovery.

Abstract
BACKGROUND The goal of this study was to evaluate the clinical effect of Regan-Morrey type II comminuted coronoid process fracture treated with mini plate through the direct anterior approach (DAA). METHODS Ten patients who underwent open reduction and internal fixation (ORIF) with mini plate through the DAA between February 2013 and August 2016 was included. There were three women and seven men, with an average age of 34.4 ± 7.5 years. At the final follow-up, the Mayo Elbow Performance Index (MEPS), Visual Analogue Scale (VAS) score, Disability of the Arm, Shoulder, and Hand (DASH) score, and the elbow range of motion were noted. RESULTS The mean follow-up was 26.3 ± 2.2 (range 24-31) months. The mean elbow arc of motion was 118.5° with a mean arc of extension of 4° ± 5.2° and flexion of 122.5° ± 7.2°.The mean forearm pronation was 72° ± 7.2°, and the mean supination was 68° ± 6.3° with a mean forearm rotation arc of 140°. The average postoperative score according to the MEPS was 91 ± 5.7 points (range 80-100 points), and all patients achieved satisfactory scores (8 excellent and 2 good). The final average VAS score was 0.6 ± 1 (range 0-3). The final average DASH score was 4.0 ± 1.6 (range 2.3-7.4). None of the patients complained about elbow instability that required secondary surgery. No complications of infection, joint incongruency, fracture nonunion, median nerve palsy, or implant failure were reported. CONCLUSIONS ORIF with mini plate through the DAA for the treatment of the type II comminuted coronoid process fractures can achieve satisfactory outcomes.

Abstract
Background The coracoid process plays an important role in maintaining the stability of the elbow joint. A fracture of the coronoid process is often treated via surgical approaches, including open reduction and internal fixation, which aim to regain a stable, flexible, and loadable joint. In this study, we compared the anterior, medial, and posterior approaches of internal fixation in the repair of fractures of the coronoid process of the ulna. Methods In this retrospective study, 147 patients with fractures in the coronoid process of the ulna were recruited and classified into the anterior group (n = 73), the medial group (n = 32), and the posterior group (n = 42) according to the surgical approach used for internal fixation. These patients were assessed with respect to incision, operative time, estimated blood loss, fracture healing, and postoperative complications. The Mayo Elbow Performance Score was used to evaluate any form of disability associated with elbow injuries. Multivariate logistic regression analysis was performed to investigate the factors influencing the efficacy of fractures of the coronoid process of the ulna. Results In the medial approach group, the operative time was longer, and perioperative blood loss and postoperative drainage volume were obviously increased compared with the anterior and posterior groups. The anterior group exhibited a better postoperative recovery compared with the medial, and posterior groups. Compared with the anterior group, fracture-healing time in the posterior group was further reduced, whereas elbow joint flexion extension and forearm rotation degree improved. Complications were significantly reduced in the posterior approach group compared with the anterior and medial groups. The factors influencing the efficacy of fractures of the coronoid process of the ulna included the Regan–Morrey classification, perioperative blood loss, and the internal fixation approach. Conclusion In summary, the approach used influences fracture healing or the outcome after osteosynthesis. The posterior internal fixation method produced satisfactory functional outcomes in patients with fractures of the coronoid process of the ulna.

Abstract
Coronoid process fractures of the ulna are difficult to treat, and are associated with stiffness, recurrent instability, and pain. Hence, treatment of coronoid process fractures are challenging for surgeons. The purpose of this study was to report the clinical outcomes of an anterior surgical approach associated with plate fixation for Regan and Morrey type II or type III fractures of the coronoid process.We evaluated 16 consecutive patients who underwent surgical treatment for fracture of the coronoid process of the ulna from March 2012 to July 2016. Ten patients had a type II fracture, and 6 patients had a type III fracture. All patients underwent surgical treatment for coronoid process fracture through an anterior approach. While preserving the neurovascular structure, all fractures were treated with buttress plate fixation, maintaining the gap between brachial artery and median nerve. Each patient was treated with concentric reduction of both the ulnotrochlear and the radiocapitellar articulations, without any evidence of elbow instability, except 1 case, who showed some medial instability.At the final follow-up, solid osseous union was confirmed for all coronoid fractures. The average time to radiologic union was 16.3 weeks. The mean flexion-extension arc was 124.25 ± 12.12 degree, with a mean flexion contracture of 8.25 ± 4.36 degree, and further flexion of 132.5 ± 9.31 degree. The mean forearm rotation arc was 167.81 ± 10.49 degree. Fifteen patients achieved a functional arc of motion. The mean Mayo elbow performance score was 92.1 points, with 12 excellent cases and 4 good cases.Coronoid process fractures of the ulna can be treated successfully with plate fixation through an anterior surgical approach, which allows for accurate reduction and rigid internal fixation and early functional exercise, resulting in a reasonable outcome.

Abstract
BACKGROUND Ulna coronoid fracture is a complicated injury and occurred in the coronal plane. Undeniably, there is no universally accepted approach for treating ulna coronoid fractures. Therefore, this study aimed at exploring the efficacy of different surgical treatments for Regan-Morrey type II and III ulna coronoid fractures. METHODS A total of 164 patients with ulna coronoid fractures were admitted and treated in department of orthopedics at Yiwu Central Hospital, the Affiliated Yiwu Hospital of Wenzhou Medical University for retrospective analysis. The baseline features (age, gender, time from injury to surgery and so on) before the surgery and different conditions during the surgery were compared. Following that, the Visual Analogue Scale (VAS) pain score was employed to evaluate the severity of preoperative and postoperative pain experienced by the patients in each group. Afterwards, Broberg and Morrey elbow score was used to evaluate elbow joint function and surgical effect of the patients. Lastly, the postoperative recovery and complications were compared. RESULTS It was firstly observed that internal fixation with mini plate and hollow screw compelled to lower average operation time and blood loss than Kirschner wire and steel wire suture. Next, the severity of postoperative pain was lessened in comparison with preoperative pain. Afterwards, mini plate and hollow screw improved elbow joint function more notable than Kirschner wire and steel wire suture, and Kirschner wire and steel wire suture resulted in higher incidence of complications and worse postoperative recovery. CONCLUSION Collectively, this study clarified that for the treatment of Regan-Morrey type II and III ulna coronoid fractures, internal fixation with mini plate and hollow screw has an overall superior surgical effect than internal fixation with Kirschner wire and steel wire suture.

Abstract
Objective To summarize the research progress in posteromedial rotatory instability (PMRI) of the elbow joint. Methods The recent researches about the management of PMRI of the elbow joint from the aspects of pathological anatomy, biomechanics, diagnosis, and therapy were analyzed and summarized. Results The most important factors related to PMRI of the elbow joint are lateral collateral ligament complex (LCLC) lesion, posterior bundle of the medial collateral ligament complex (MCLC) lesion, and anteromedial coronoid fracture. Clinical physical examination include varus and valgus stress test of the elbow joint. X-ray examination, computed tomography, particularly three-dimensional reconstruction, are particularly useful to diagnose the fracture. Also MRI, arthroscopy, and dynamic ultrasound can assistantly evaluate the affiliated injury of the parenchyma. It is important to repair and reconstruct LCLC and MCLC and fix coronoid process fracture for recovering stability of the elbow joint. There are such ways to repair ligament injury as in situ repairation and functional reconstruction, which include direct suturation, borehole repairation, wire anchor repairation, and transplantation repairation etc. The methods for fixation of coronal fracture include screw fixation, plate fixation, unabsorbable suture fixation, and arthroscopy technology. Conclusion It is crucial that recovering the stability of the elbow joint and early functional exercise for the treatment of PMRI. Individual treatment is favorable to protect soft tissue, reduce surgical complications, and improve the functional recovery and the quality of life.
