Fracture of the metacarpal bone: diagnosis, treatment, and rehabilitation

Definition and Causes of Metacarpal Bone Fracture

A fracture of the metacarpal bone is an injury to the bone located in the wrist area, caused by mechanical impact that exceeds its strength. Metacarpal fractures can occur as a result of falling on an outstretched hand, blows, or injuries sustained during sports activities.

The causes of metacarpal fractures can be diverse, including injuries from falls, accidents, or sports injuries. Risk factors include osteoporosis, decreased bone density, as well as increased stress on the bone due to sports activities or daily actions. It is important to promptly identify and treat metacarpal fractures to prevent complications and ensure rapid recovery of hand functions.

Etiology of metacarpal bone fracture

A fracture of the metacarpal bone is one of the most common types of fractures in orthopedics and traumatology. Its etiology is mainly associated with injuries caused by falls onto an outstretched hand or direct blows to the wrist area. This type of injury is especially common among athletes, as well as among people engaged in physical labor where the hands are subject to increased loads. Furthermore, weakened bones, such as those found in osteoporosis, increase the risk of a metacarpal fracture even with minor trauma.

  • Injuries and bruises: Falls onto an outstretched hand or blows to the wrist area can lead to a fracture of the metacarpal bone.
  • Sports injuries: Athletes have an increased risk of metacarpal bone fractures due to excessive strain on the wrist.
  • Physical activity: People engaged in physical work are subject to an increased risk of metacarpal bone fractures.
  • Osteoporosis: Weakened bones in patients with osteoporosis are more susceptible to fractures even with minor injuries.
  • Aging: As people age, bones lose density, which increases the likelihood of fractures from mechanical impact.

The clinical picture of a metacarpal bone fracture.

In a metacarpal fracture, characteristic clinical signs are observed, such as swelling and tenderness in the wrist area, restricted movements in the wrist and fingers. The patient may experience localized pain upon palpation and when attempting to flex and extend the wrist. Additionally, swelling and bruising at the fracture site may also be observed in the patient.
One of the characteristic symptoms of a metacarpal fracture is a change in the shape of the wrist, which may be visually noticeable. The clinical picture may vary depending on the type and severity of the fracture, so it is important to conduct a thorough examination of the patient, including X-rays, to accurately determine the diagnosis and develop an appropriate treatment plan.

  • Swelling and tenderness: in the case of a metacarpal fracture, swelling and tenderness are observed in the wrist area, which may be related to tissue damage and the development of inflammation.
  • Restricted movement: the patient may experience a restriction of movement in the wrist and fingers due to pain and bone deformation.
  • Localized pain: upon palpation and attempts to flex and extend the wrist, the patient may experience localized pain.
  • Bluish skin discoloration: at the fracture site, there may be a bluish discoloration of the skin due to impaired circulation and bleeding.
  • Change in wrist shape: one of the characteristic symptoms of a metacarpal fracture is a change in the shape of the wrist, which may be visually noticeable.

Approaches to the treatment of metacarpal bone fracture: expert opinions

Experts in the field of orthopedics and traumatology justify various approaches to treating a metacarpal fracture depending on the type of fracture, its location, and the characteristics of the patient. Some specialists may recommend conservative treatment using a plaster cast or external fixators, while others may advocate for surgical intervention aimed at restoring anatomical structures and recovering wrist functionality.
Experts also emphasize the importance of an individualized approach to each patient when choosing a treatment method for a metacarpal fracture. The patient’s characteristics, overall health status, age, lifestyle, and the extent of the injury should be considered when deciding on the best way to restore wrist function and prevent possible complications.

Methods for diagnosing a metacarpal bone fracture

For the diagnosis of a metacarpal fracture, various methods are used, including clinical examination and the appointment of X-rays. During the examination, the doctor assesses clinical symptoms such as tenderness, swelling, changes in the shape or function of the wrist. X-rays allow for confirmation of the diagnosis, determination of the nature and location of the fracture, and to make a decision on the optimal treatment method.

Additional diagnostic methods, such as computed tomography (CT) or magnetic resonance imaging (MRI), may be used in complex cases when a more detailed study of injuries or assessment of the condition of surrounding tissues is necessary. Accurate diagnosis of the metacarpal fracture plays an important role in determining the optimal treatment plan and prognosis for the patient.

  • Clinical examination: The doctor assesses tenderness, swelling, and changes in the shape and function of the wrist.
  • X-ray: X-ray images allow for the determination of the presence, nature, and location of the fracture.
  • Computed tomography (CT): Used in complex cases for a more detailed study of injuries and surrounding tissues.
  • Magnetic resonance imaging (MRI): A method that provides detailed images of internal structures for additional diagnostics.
  • Ultrasound examination: A technique that can be used to assess the condition of soft tissues and blood vessels in the area of the fracture.

Methods for treating a metacarpal bone fracture

The treatment of a metacarpal bone fracture depends on many factors, including the nature and severity of the fracture, the age of the patient, and the presence of accompanying diseases. In the case of moderate fractures, conservative treatment may be sufficient, including the application of a plaster cast to provide support and fixation for the healing of the bone. In more complex cases, when the fracture is displaced or accompanied by damage to adjacent tissues, surgical intervention may be required.

Surgical treatment of a metacarpal bone fracture may include osteosynthesis (internal fixation of bones using plates, screws, or nails) or exostosis if the bone requires additional support for healing. Early and proper treatment of a metacarpal bone fracture, considering the individual characteristics of the patient, helps prevent possible complications and ensures the best prognosis for the recovery of hand function.

  • Conservative treatment: Includes applying a plaster cast for fixation and support of fracture healing, and using physiotherapy to restore joint mobility.
  • Surgical osteosynthesis: Used in cases of severe and displaced fractures for internal fixation of bones with plates, screws, or nails.
  • Exostosis: Used to provide additional support and fixation of the bone in cases requiring further stabilization.
  • Therapeutic exercise: Recommended for restoring strength and mobility in the affected joint after fracture healing.
  • Individual approach: Fracture treatment of the metacarpal bone should be tailored to the individual characteristics of the patient, considering age, overall health condition, and nature of the injury.

Prevention measures for metacarpal bone fracture

Prevention of metacarpal bone fractures includes a number of measures aimed at strengthening bone tissue and preventing injuries. Regular physical exercise, especially physical activities for the hands to improve muscle tone and bone density, contributes to strengthening bones and reducing the risk of fractures. Additionally, wearing protective gear during sports or physical work can help prevent injuries, including metacarpal fractures.
An important aspect of prevention is also proper nutrition, rich in calcium and vitamin D, which are essential for bone health. Preventing falls and using caution in daily life also help reduce the risk of metacarpal fractures, especially in individuals with weakened bone tissue.

  • Physical activity: Regular exercises, including strength training for the arms, help improve muscle tone and strengthen bone tissue.
  • Wearing protective gear: When engaging in sports or physical work, protective equipment should be used to prevent injuries, including fractures of the metacarpal bone.
