Examination of Pediatric Elbow
Published in Nirmal Raj Gopinathan, Clinical Orthopedic Examination of a Child, 2021

The olecranon is the most prominent bony landmark felt posteriorly in a flexed elbow and palpated by moving the fingers proximally along the subcutaneous border of the ulna. It may be tender in an olecranon fracture, and abnormal projection of the olecranon process posteriorly may be seen in an SC humerus fracture in children and posterior dislocation of the elbow in adults. Swelling resulting from olecranon bursitis (student’s elbow) will be more distinct and sharply demarcated like a “goose egg” over the olecranon process. Olecranon apophysitis may present as a point of tenderness in the olecranon and along with triceps insertion due to overuse.

Request an X-ray to confirm the diagnosis and to delineate the degree of fracture displacement, angulation or comminution. Anterior dislocation of the elbow may accompany a displaced olecranon fracture.

A 38-year-old man presents with elbow pain after a fall. AP and lateral radiographs demonstrate the presence of an 8 mm anterior fat pad and a posterior fat pad. No obvious fracture line can be identified. Which of the following is most likely? Ulna fracture.No fracture.Olecranon fracture.Radial head fracture.Humeral shaft fracture.
Elbow dislocation with lateral condyle and coronoid fractures

In CT scan, an anteromedial coronoid fracture could be recognized [8]. O’Driscoll described three types of coronoid fracture (rim only (I), rim and tip (II), rim, tip and sublime tubercle (III)). This type could be associated with the elbow dislocation, olecranon fracture or rarely radial head fracture [9]. Of course, only a slight elbow incongruity may be present and the lesion could be missed; this could rapidly lead to elbow arthrosis. Then, any isolated coronoid fracture should be further studied by examination and CT scans to assess this type of fracture. Our patient has a coronoid fracture and lateral condyle fracture with elbow dislocation. The coronoid fracture in this patient is assessable by the Regan Morrey classification, but an intact radial head rules out the terrible triad of the elbow.
Design approaches and challenges for biodegradable bone implants: a review
Published in Expert Review of Medical Devices, 2021
The journey of Internal fixation medical devices as a fractured bone healing aid began more than 100 years ago with metal plating being used in 1895 for orthopedic surgery [1]. Many different types of plates emerged later, corresponding to types and position of fractures, for example, clover leaf plate, spoon plate, L-plate, T-plate, cobra head plate, reconstruction plate, straight plate, tubular plate, etc. An adjustable locking plate was designed and received good response because of offering many advantages, such as allowable movement to segmental fractured bone for structural stability and precise positioning of disconnected segments [36]. These plates were usually fixed with screws made up of NB materials. In fact, screws were used in 1850 to fixate an olecranon fracture where two wooden screws and a leather strap were used. In 1920, stainless steel made its entry as bone screw material. It had reasonable and allowable biocompatibility. Its modified design with some additional features incorporated for human bone was developed in 1940 [16]. Three types of screws have been mainly used for joints or oblique fractures: V-shape threaded, square-threaded and buttress-threaded. Out of them, the buttress-threaded screws have been one of the most preferred options for surgeons as they provide comparatively high axial thrust and pull-out resistance [14]. The NB implants have been used in biomedical engineering for long but design investigations have been relatively few. For bone fracture fixation applications, Mg-alloys have been frequently used for manufacturing biodegradable bone implants.A brief history depicting some examples of biodegradable implants made by Mg or its alloys is enumerated in Figure 2[37–43].
A novel method of acromioclavicular joint separation fixation using a knotless dog bone technique
Published in Baylor University Medical Center Proceedings, 2019

A 66-year-old man presented at a level 1 trauma center after fall from a 12-foot ladder, which led to a left Rockwood Grade V AC separation. Additional injuries included an ipsilateral olecranon fracture treated in a splint, a left pneumothorax, and multiple rib fractures. The patient was admitted to our surgical intensive care unit for management of his rib fractures and ultimately underwent extensive rib plating. He did well postoperatively from his rib fixation and we then proceeded with surgery to correct the AC joint separation 5 days after injury.
