Scaphoid fractures usually occur due to a fall on the out-stretched hand. Most patients complain of pain within the wrist with difficulty in gripping objects. There are various ways one can experience a scaphoid fracture, and the type of fracture may change A scaphoid fracture may also be described by the location. It may be at the far end (distal pole), in the middle (waist), or in the near end (proximal pole). The fractures at the near end (nearer to the elbow, proximal pole) have a poorer blood supply and therefore are less likely to heal without surgery. In addition, the near end (proximal pole) is at risk for dying (avascular necrosis) without prompt treatment.

Scaphoid Fracture Symptom

The most typical symptoms of a scaphoid fracture are visible swelling and tenderness near the thumb. These symptoms can be mistaken for a more gentle injury, but if bruising,
The signs of a scaphoid fracture include pain and swelling at the base of the thumb, and tenderness of the affected area. Often misdiagnosed through the patient themselves, a scaphoid fracture in many cases is thought to be a sprained wrist. Though if the pain doesn't subside dramatically after a day, have a doctor or emergency-room physician checks the region, you may have incurred a scaphoid fracture.

Scaphoid Fracture Causes

A scaphoid fracture most often results from a fall with an outstretched hand. Motor vehicle crashes, and workplace injuires can also cause scaphoid fractures The outcome of scaphoid fractures is largely dependent on the location of the burglary the bone and also the amount the navicular bone have displaced or shifted. Fractures close to the end of the bone toward the hand have the greatest blood supply and heal the best. Fractures located in the core scaphoid (the waist) or closer to the forearm (the proximal pole) sometimes have trouble healing since the blood supply to these areas is poor.

A scaphoid fracture causes tenderness directly within the bone. This is an area referred to as the anatomic snuffbox Your pain may increase when you move your thumb or grip things. Your initial pain may decrease over days or weeks. Scaphoid fractures usually do not cause bruising or significant swelling, which is the reason they are often mistaken for any sprained wrist.

Scaphoid Fracture Healing time

Healing duration of scaphoid fracture (treated in a cast) can take anything from 6 to 10 weeks or maybe even additional time. Some scaphoid fractures possess a difficult time healing. There might be delayed healing, or sometimes the bone will not heal, leading to a nonunion. In these instances, follow up surgery might be necessary to insert bone grafts. The bone grafts promote healing simply because they either bring a circulation to the area, or growth factors that enhance healing.

Scaphoid Fracture diagnosed

It is necessary that a scaphoid fracture be diagnosed early because the scaphoid bone includes a poor blood supply and will not heal well with continued stress. Furthermore, when the scaphoid bone fractures, so that the fracture displaces (where two or more pieces of bone have moved from one another), the odds of the bone healing appropriately without medical intervention are extremely small. If medical intervention doesn't happen soon enough and the circulation is not reestablished, the bone may degenerate and necrosis (tissue death) from the bone may occur.

If your scaphoid fracture is suspected. Your physician can diagnose a scaphoid fracture by examining your wrist and taking X-rays. Sometimes scaphoid fractures don't show up on initial X-rays. The X-rays may be repeated later, or computed tomography (CT) scans or magnetic resonance imaging (MRI) scans can be utilized because they show more detail. CT scans are often performed, as the degree of fracture displacement is often hard to determine from plain X-rays.

Scaphoid Fracture Treatment

The most common surgical treatment for a scaphoid fracture is percutaneous screw fixation, where the two disconnected areas of the scaphoid are gathered with a small screw, and allowed to heal normally. This method generally allows for much faster healing than 12 weeks of wearing a cast, if you lead an active lifestyle, this method will most likely be the best for you personally. In some cases if the fracture doesn't heal, a scaphoid non-union, a bone grafting may be necessary, which entails a doctor taking pieces of bone from another part of the wrist and placing it between your two parts of the scaphoid. The goal of this is to have the healthier bone encourage growth of the scaphoid, so that it can join in a cohesive unit.

The treatment plan will depend on the severity of the fracture as noted about the x-rays and the patient's medical condition, activity level, and desires. Patients who have well-aligned or non-displaced.this fractures might be treated without surgery. This usually takes a cast immobilizing the thumb and wrist for 2-3 months before fracture's heal. Follow-up x-rays are obtained in a clinic to evaluate how the fracture is healing. Over 90% of patients treated appropriately in this way will heal their scaphoid fracture. Treatments are often helpful in improving flexibility and strength following the cast is removed. It may take up to a year for strength and range of motion to improve to be maximal, even with therapy. Occasionally, people do not regain full range {of motion|of movement
