Splint to immobilise – usually the little and ring fingers This fracture usually does not involve the joint surface and so arthritis in later life is unusual after this fracture. In general, the above two potential issues are the key reasons why surgery would be offered to people with these fractures. This can cause significant functional compromise to the hand. Little finger rotation can occur such that it overlaps the ring finger when one makes a fist. Significant angulation will cause a permanent lag. This is common finding initially in most of these fractures but it usually resolves. Volar angulation can cause an inability to fully straighten the little finger (extensor lag). This can cause two of the potential problems associated with these fractures: The fracture can result in the head of the 5th metacarpal (MCP joint) experiencing significant volar (flexor/forward) angulation and/or rotation at the fracture site. The degree to which the fracture has displaced determines the type of complications that can arise with these fractures. However, they will result in a loss of prominence of the little finger knuckle. In general, Boxer’s fractures are extremely common and usually do not require surgery and cause no functional compromise. If a fracture involves the joint surface then arthritis may develop later in life. This swelling can cause stiffness to the hand and fingers. Overall, swelling occurs at the site of the fracture and often affects the whole hand. This swelling is magnified by the bleeding that occurs from the bone ends at the site of the fracture. Therefore, significant soft tissue trauma also occurs with its resultant swelling. The forces required to fracture a bone also act on the surrounding soft tissues. Even though the laceration is often no more than a small puncture wound, these are at very high risk of developing an infection including septic arthritis and should be treated aggressively. This typically occurs in boxer’s fractures when the fist strikes a tooth. A significant force can result in the bone ending up multiple pieces (comminuted) or become significantly displaced resulting in a deformity.Īny laceration overlying, or associated with, a fracture is referred to as a compound fracture. It typically results from a punching mechanism. Note that the fracture is back in near perfect position.A Boxer’s fracture refers to a fracture involving the neck of the 5th metacarpal. Depending on the healing, the patients may have to stay out of physical sports for 8-10 weeks.īoxers fracture after percutaneous pinning. These pins or wires will stay in place for about 6 weeks and then we can take them out in clinic (almost painless process). Therefore, we placed two k- wires to hold the bones in position. However, as expected, it was unstable- it kept falling back out of position. The patient was taken to the operating room and the fracture was able to be reduced (ie, pushed back into place) without an incision. In this image, I have added an arrow to point out the angulation of the metacarpal bone in case it is not clear.īoxers fracture with arrow demonstrating the angulation which measures about 90 degrees. Severe boxers fracture, 5th metacarpal neck fracture I believe the fracture is clear on the little finger metacarpal. Most doctors would agree that this is too much deformity and something should be done. The following patients injured himself in basketball and had a notable deformity measuring almost 90 degrees. Doctors do not agree on what degree of angulation is safe but when the angle is too severe, a reduction to put the bones back in better alignment or a surgery are often recommended. Rarely, this fracture may not do well in a cast or splint due to more angulation or deformity. Once healed, people get back to activities but sometimes notice that their knuckle is not quite as visible. Thankfully, most of these 'boxer's fractures' heal uneventfully in a cast or in a brace. We most commonly see this fracture when an adolescent or young adult male punch someone or something. This fracture happens to the pinky finger metacarpal when the force of a punch (or something similar) is absorbed by the metacarpal. It is actually not a good name because boxers don't get this fracture because they understand how to safely punch. The most common metacarpal fracture is often called a 'boxer's fracture'. These injuries happen for a number of reasons- direct force such as in football, a slash across the hand in in hockey, or a punching force in any sport (or non- sport). One of the most common hand injuries in the athlete is a broken hand bone or metacarpal fracture.
