The Novel Hooked Kirschner Wire Technique for Ulna Coronoid Process Fractures

Background@#The aim of this study was to introduce a novel technique to improve the ease of fixing of even small fragments of the coronoid process and report the clinical outcomes of this method. @*Methods@#Forty-nine patients with ulnar coronoid process fractures fixed using the hooked Kirschner wire (K-wire) technique at our hospital from 2007 to 2019 were reviewed. Radiological features and fracture union were assessed using simple radiographs.Functional outcomes of the treated elbows were evaluated at the final follow-up visit using the Mayo Elbow Performance Score (MEPS). @*Results@#All patients were examined at a mean follow-up of 17.7 months (range, 6–62 months). We observed bony union in patients at a mean of 10.9 weeks (range, 6–22 weeks). The mean flexion and extension ranges of the elbow were 132.0° (range, 106° –151°) and 4.5° (range, –20° to 30°), respectively. The mean pronation and supination ranges of the forearm were 81.1° (range, 60°–90°) and 88.3° (range, 60°–120°), respectively. The mean arc of the elbow was 127.4° (range, 78°–160°). All patients were evaluated using the MEPS at the final follow-up visit, with a mean score of 96.9 points (range, 80–100 points). One case of coronoid nonunion was observed and re-fixation was performed. One case of infection was observed and also treated with additional surgery. Three patients complained of ulnar nerve symptoms and 1 patient underwent surgical release for tardy ulnar nerve palsy. @*Conclusions@#Despite its limitations, the hooked K-wire technique was a useful method for even smaller coronoid process fractures. K-wires were also a useful temporary intraoperative fixation method and could provide permanent fixation.

Treatment of Traumatic Sternoclavicular Joint Anterior Dislocation with a Sternal Fracture / 대한정형외과학회잡지

A traumatic dislocation of the sternoclavicular joint is a rare injury, and among them, anterior dislocation is more common than a posterior dislocation. Posterior dislocation is a potential risk by compressing the mediastinal structures, but an anterior dislocation has not been considered a risk. Traumatic sternoclavicular joint anterior dislocation associated with anterior angulation of a sternal fracture can develop mediastinal compression and have a risk in the same way as a posterior dislocation. This case report is about a traumatic sternoclavicular joint anterior dislocation with a sternal fracture accompanied by mediastinal compression that was treated surgically using a plate and showed relatively good clinical results. This rare case is reported along with a review of the relevant literature.

Crossbar Technique for the Failed Clavicular Hook Plate Fixation in an Acute Acromioclavicular Joint Dislocation: Salvage for Acromial Fracture after Clavicular Hook Plate

We experienced acromial erosion and subsequent fracture after the treatment of Rockwood type V acromioclavicular dislocation with hook plate and coracoclavicular ligament augmentation. It was treated by using a surgical technique to address an acromial fracture and subsequent losses of reduction in acromioclavicular joint with two trans-acromial cortical screws (crossbar technique). The reduction state of acromioclavicular joint could be maintained by these two screws. Our crossbar technique could be considered as a good salvage procedure for the reduction loss caused by cutout or significant erosion of acromion after insertion of clavicular hook plate.

The Surgical Outcomes of Olecranon Fracture Dislocation of the Elbow / 대한정형외과학회잡지

PURPOSE: The purpose of this study is to evaluate the surgical outcomes of olecranon fracture dislocation in accordance with the direction of the dislocation. MATERIALS AND METHODS: From December 2006 to February 2016, the surgical outcome in patients who had been followed-up for a minimum of 6 months accompanied with olecranon fracture and elbow instability were reviewed retrospectively. We classified olecranon fracture as either the anterior type or the posterior type. Moreover, we evaluated the clinical results by the Mayo elbow performance scores (MEPS) and checked for any associated injury, age, injury mechanism, and complication. RESULTS: Fourteen patients had anterior transolecranon fracture dislocation, with an average age of 46 years. The associated lesions were radial head fractures found in 2 patients (14.3%) and coronoid process fracture found in 5 patients (35.7%). Patients with anterior transolecranon fracture showed an average MEPS of 93.2 (70–100). Eight patients with posterior olecranon fracture dislocation had an average age of 66 years (22–87 years). The associated lesions were radial head fractures in 6 patients (75.0%) and coronoid process fracture in 8 patients (100%). Patients with posterior olecranon fracture dislocation showed an average MEPS of 94.4 (80–100). In comparison with the anterior type, posterior type occurred more frequently in elders and showed a greater association with injuries, such as radial head fracture and coronoid process fracture. However, there was no significant difference between the two groups with respect to the clinical outcome. CONCLUSION: There were differences in frequency of associated injuries and age in accordance with the direction of olecranon fracture dislocation. Moreover, good clinical outcomes were achieved by surgical treatment.

Helical Plating for Fractures of the Proximal Humeral Shaft / 대한정형외과학회잡지

PURPOSE: To evaluate the effectiveness of internal fixation with a helical plate for displaced proximal humeral shaft fractures by analyzing the clinical outcomes of patients. MATERIALS AND METHODS: Fourteen displaced fractures of the proximal humeral shaft were treated by open reduction and internal fixation (ORIF) or by minimally invasive plate osteosynthesis (MIPO) with the use of helical locking compression plates. We evaluated the adequacy of reduction, time-to-fracture healing, range of motion of the shoulder, and postoperative complications. The functional outcome of the shoulder was evaluated using a Constant-Murley shoulder score. RESULTS: Anatomical reduction of the fracture was obtained in nine cases treated by ORIF, and anatomical alignment was obtained in five cases treated by MIPO. All fractures were healed in an average of 14.9 weeks. The active range of motion of the shoulder was fully recovered in five cases, and restricted in nine cases, at around 12 months after surgery. The mean Constant-Murley shoulder score was 87.4 points, at around 12 months after surgery. There were no major complications, such as neurovascular injury, infection, loss of fixation, and nonunion. CONCLUSION: Helical locking compression plating for proximal humeral shaft fractures is a safe and effective surgical method in obtaining satisfactory fracture healing and functional outcome because it provides stable fixation and avoids complications related with lateral plating.

Clinical Results of Open Reduction and Internal Fixation in the Coronal Plane Articular Fracture of the Distal Humerus / 대한정형외과학회잡지

PURPOSE: The purpose of this study is to evaluate the surgical outcomes according to the Ring's classification system in patients with the distal humeral coronal plane articular fracture after treatment with open reduction and internal fixation (OR/IF). MATERIALS AND METHODS: Patients with the distal humeral coronal plane articular fracture treated with OR/IF in the three hospitals were reviewed retrospectively. The patients were evaluated clinically and radiographically according to the Ring's classification system. RESULTS: Eleven patients, including three males and eight female patients, with a mean age of 55 years (15–88 years) were enrolled in this study. Average Mayo elbow performance score was 85 (60–100), four patients had excellent, four had good, and three had fair results. Fracture union was achieved in ten of 11 patients who underwent open reduction and internal fixation. In the analysis of the results according to Ring's classification, patients presenting fracture of the posterior aspect of the lateral column showed worse clinical results than those who did not. It was the same for the patient presenting fracture of the posterior aspect of the trochlea. CONCLUSION: The open reduction and internal fixation provides good clinical and radiologic outcomes for the distal humeral coronal plane articular fracture. Our results suggest that the type of fracture involvement with posterior aspect of trochlear or capitellum can result in poor clinical outcomes.

At 10 years of follow-up, satisfactory functional recovery was observed. Herein, we report on a case of displaced distal femoral epiphyseal birth fracture with literature reviews.

An Anterosuperior Deltoid Splitting Approach for Plate Fixation of Proximal Humeral Fractures

BACKGROUND: The purpose of this study was to evaluate the usefulness and safety of the anterosuperior deltoid splitting approach for fixation of displaced proximal humeral fractures by analyzing the surgical outcomes. METHODS: Twenty-three patients who could be followed-up for at least 8 months after the treatment of displaced proximal humeral fractures through the anterosuperior deltoid splitting approach were enrolled. We evaluated the reduction of the fractures and surgery-related complications at the last follow-up using X-ray results and clinical outcomes comprising the University of California at Los Angeles (UCLA) scoring system and the Korean Shoulder Society (KSS) score. RESULTS: At the last follow-up of patients treated using the anterosuperior deltoid splitting approach for internal fixation of proximal humeral fractures, we found 22 cases (95.6%) of bone union, a mean UCLA score of 28.3 (range, 15 to 34) and a mean KSS score of 82.1 (range, 67 to 95). Various surgery-related complications were noted; a case of varus malunion after fracture displacement, a case of nonunion, a case of delayed union, two cases of impingement, and a case of partial axillary nerve injury, which recovered completely through the follow-up. CONCLUSIONS: Plate fixation using the anterosuperior deltoid splitting approach could be another reliable option for treating displaced proximal humeral fractures.

In recent years, there has been a noticeable increase in contrast media extravasation injury. However, definite guidelines for the treatment of the injury have not yet been established, although it causes severe complications such as compartment syndrome, skin necrosis etc. We try to introduce conservative management with a thorough review of the relevant literatures about successful treatment and functional restoration from contrast media extravasation injury without any complications.

Reduction of Anterior Shoulder Dislocations by Acromion Upholding Method (Shin's Method): Technical Note / 대한정형외과학회잡지

The most common form of joint dislocation is anterior shoulder dislocation. There are a number of available techniques to reduce, but which have a possibility to be happened many kinds of complications like brachial plexus injury, axillary nerve injury and fracture of the humerus. In addition, the drugs we use for the reduction have potential side effects such as cardiovascular complications and respiratory arrest. We are trying to introduce new reduction technique aimed at minimizing the complications and increasing the success rate, which was used in 23 cases and all of them were successfully reduced without complications.

Cryptococcal Tenosynovitis of the Hand in a Patient with Rheumatiod Arthritis: A Case Report

Cryptococcosis is a fungal infection caused by Cryptococcus neoformans which is frequently occurred in the immunosuppressed host. Any organ or tissue may become infected, however, tendon sheath infection is extremely rare. We report a case of primary cryptococcal tenosynovitis after direct skin injury in a patient with rheumatoid arthritis who has been treated with methotrexate and leflunomide.

Distal Intersection Syndrome of the Wrist: Three Cases Report

Distal intersection syndrome indicates simultaneous tenosynovitis or tendinosis of the second and third extensor compartment where extensor pollicis longus cross with the tendons of the second extensor compartment. We report three cases of distal intersection syndrome which differ from usual intersection syndrome.

The Surgical Outcomes of Clavicle Lateral End Fractures Fixed with the Oblique T Locking Compession Plate

PURPOSE: The purpose of this study is to evaluate the surgical outcomes of the clavicle lateral end fracture fixed with an oblique T locking compression plate (LCP). MATERIALS AND METHODS: Fourteen clavicle lateral end fractures were fixed with the oblique T-LCP and followed up for at least 1 year after the surgery. Thirteen cases were unstable Neer type II fractures and one case was nonunion of the Neer type I fracture. The mean age was 46 years of age (range, 26~70). In ten cases, augmenting sutures with the absorbable suture material were placed in the coraco-clavicular ligament and around the plate and the clavicle to improve the stability of fracture fixation. Autogenous iliac bone graft was done in four cases. The clinical outcomes were evaluated by using UCLA scoring system and KSS (Korean Shoulder Score). RESULTS: The mean UCLA score was 33.5 and the mean KSS was 94.9. Average time of bone union was 11.9 weeks (range, 6~28), including 1 case with a delayed union. There was no complication such as loss of fixation or nonunion. CONCLUSION: Fixation with the oblique T-LCP is a good option providing reliable functional results in clavicle lateral end fractures.

Pyogenic Arthritis of the Shoulder in Patient with Infective Endocarditis: A Case Report

PURPOSE: We report a case of pyogenic arthritis of the shoulder secondary to infective endocarditis. MATERIALS AND METHODS: A 70 year-old male who had suffered from pyogenic arthritis of the left shoulder secondary to infective endocarditis was treated with artificial valvuloplasty, arthroscopic synovectomy and drainage. RESULTS: Infection was cured and the patient achieved a good functional outcome. CONCLUSION: Pyogenic arthritis of the shoulder is rarely associated with infective endocarditis. However, if the symptoms are misdiagnosed as musculoskeletal symptoms associated with infective endocarditis, serious complications may arise. As such, musculoskeletal symptoms associated with infective endocarditis should be paid careful attention.

The Surgical Outcomes of Isolated Greater Tuberosity Fractures of the Proximal Humerus Fixed with the Spring Plate

PURPOSE: The purpose of this study was to evaluate the surgical outcomes of isolated greater tuberosity fractures of the proximal humerus fixed with the spring plates. MATERIALS AND METHODS: Fourteen patients who could be followed up at least 1 year after the surgical treatment of isolated greater tuberosity fracture were evaluated. Their mean age was 51 years (range, 25~73 years). The deltopectoral approach and fixation with the spring plate were performed in all cases. The spring plate was used in all cases. In some circumstances, sutures incorporating the rotator cuff, interfragmentary screw or tension band wire were added. We evaluated the clinical outcomes using UCLA scoring system and KSS (Korean Shoulder Score). RESULTS: The mean UCLA score was 29.8 and the mean KSS was 89.4. The average time of bony union was 10.2 weeks (range, 7~14 weeks) after the surgery, including 1 case that was performed the secondary operation due to metal failure. The shoulder stiffness were observed in 4 cases and one case of infection was treated well without operation. CONCLUSION: In the treatment of isolated greater tuberosity fractures of the proximal humerus, the spring plates fixation can be a good surgical option providing reliable functional results.
