Open treatment of an ulnar shaft fracture involves a surgical procedure where the fractured bone is directly accessed and realigned. The ulna is one of the two long bones in the forearm, located on the side opposite the thumb, and the shaft refers to the long, central portion of the bone. An ulnar shaft fracture, often termed a nightstick fracture, typically occurs due to a direct impact to the ulnar side of the forearm, commonly when an individual attempts to shield themselves from a blow. This procedure includes the process of open reduction, which means that the fracture is corrected through a surgical incision rather than through closed manipulation. During the surgery, an incision is made over the fracture site, allowing the surgeon to dissect through the fascia, which is the connective tissue surrounding the muscles. The incision is strategically placed between the extensor carpi ulnaris and the flexor carpi ulnaris muscles to provide optimal access to the fracture. Once the fracture site is exposed, the periosteum, a dense layer of vascular connective tissue enveloping the bone, is incised and elevated to clear the area of any debris. The fractured bone is then realigned to its proper anatomical position, and internal fixation is applied as necessary, which often involves the use of a plate and screw device to stabilize the fracture and promote healing.
