“…In the course of CT, people are exposed to more radiation. Particularly in comminuted fractures, care is taken to avoid over compression at the fracture site that would narrow the olecranon to coronoid distance [17]. In our study, high correlation was found between POH and UTW, RTW, TW.…”

“…Non-displaced fractures can be treated with a short period of immobilization followed by gradually increasing range of motion [6]. In cases with the displaced fracture pattern, the proximal ulna can be stabilized surgically by the use of dorsal plates, tension band wiring, and intramedullary screws [3,6,9,10,17]. The goals of the treatment are restoration of the normal contour and dimension of the trochlear notch to restore stability, healing of the fracture to restore triceps function, and early mobilization of the elbow to limit stiffness [9].…”

The unique bony architecture of the proximal ulna presents particular difficulties for the implants used in fracture fixation and arthroplasty of the elbow. Knowing the detailed anatomy of the variations of proximal ulna will guide the surgeon to obtain a more reliable length of the olecranon and to offer a safe place for Kirschner wire replacement concerning humero-ulnar joint functionality. In this study, PUTA was also defined. The angle determines the rotation of the proximal ulna and it has a great importance for the movements of the joint. The measured angulations will help the surgeon to design the proper prosthesis for the maintenance of the functions of the elbow joint.

“…When a transosseous suture, wire, or screw passing the posterior border of the proximal ulna is used, the knot of a wire or the head of a screw is located on posterior border of the proximal ulna, which can cause skin irritation or pain. If screw fixation of the coronoid fragment is performed on the posterior border of the ulna, it is available only for a simple coronoid pattern and the reduction should be confirmed by fluoroscopy because an anatomical reduction is difficult to conduct [17]. Ring insisted that precise anatomic alignment was difficult to accomplish with suture fixation and can be achieved by restoring the anterior capsular insertion and anterior bony buttress [7].…”

The purpose of the present study was to determine the clinical outcome and prognostic factors after applying the coronoid plate fixation technique who had sustained type II or III coronoid process fractures. Fifteen consecutive patients were enrolled in this study. The mean arc of flexion-extension was 116°with a mean flexion and flexion contracture of 126°and 11°, respectively. The mean arc of forearm rotation was 158°with a mean pronation and supination of 78°and 80°, respectively. The mean Mayo Elbow Performance Score (MEPS) was 88 points (range, 70-100 points), which corresponded to an excellent result in ten elbows, good result in four and fair result in one. All the isolated coronoid fractures (8 patients) (there was no combined injury) and nine of the eleven (82%) noncomminuted coronoid fractures (the existence of one or two fracture fragments) had excellent functional results in accordance with the MEPS (average MEPS was 93.8 and 93.3, respectively). Patients with less favorable results according to the MEPS had lateral side injuries, such as lateral collateral ligament injures or radial head fractures (mean MEPS 78.0) The average functional score (MEPS) of the patients showing signs of arthritic changes was 76.7. Based on our experience, coronoid plate fixation of type II and III coronoid process fractures is an acceptable and alternative method that can provide good results. However, acceptable clinical outcomes are not only related to the successful rigid internal fixation of the coronoid fracture but depend on the severity of the primary injury and associated soft tissue injuries. The comminution of the fracture fragment, associated lateral collateral ligament injuries, and posttraumatic arthritic changes can be considered indicators of a poor functional outcome.

“…In previous studies, 10% to 15% limitation in arc of motion compared to the contralateral arm was observed in up to 75% of patients. [36][37][38] Wound healing is often problematic in high-energy injuries. In case of severe swelling, delayed surgery is inevitable.…”

Since the olecranon fractures are caused by relatively low-energy injuries, such as a fall from standing height, they are usually found without comminution. Less commonly they can be developed by high-energy injuries and have severe concomitant comminution or injuries to surrounding structures of the elbow. Because the fracture by nature is intra-articular with the exception of some avulsion-type fracture, a majority of olecranon fractures are usually indicated for surgical treatment. Even if there is minimal displacement, surgical treatment is recommended because there is a possibility of further displacement by the traction force of triceps tendon. The most common type of olecranon fracture is displaced, simple non-comminuted fracture (that is, Mayo type IIA fractures). Although tension band wiring was the most widespread treatment method for these fractures previously, there is some trends toward fixation using locking plates. Primary goal of the surgery is to restore a congruent joint and extensor mechanisms by accurate reduction and stable fixation so that range of motion exercises can be performed. The literature has shown that good clinical outcomes are achieved irrespective of surgical fixation technique. However, since the soft tissue envelope around the elbow is poor and the implants are located at the subcutaneous layer, implant irritation is still the most common complication associated with surgical treatment.
