Hand surgery: politicization and ulnarization—what do you need to know?

Reconstructive surgery of the upper limbs is becoming an increasingly important area of medicine. In our article, we will discuss the process of polysynthesis and ulnarization, explaining the surgical techniques, benefits, and impact of the procedure on patients' future lives.

Hand surgery – preliminary information

Hand surgery is necessary in cases of uncorrectable congenital defects, serious injuries, or diseases. The most common indications for surgery include:

• hand and finger fractures – complex fractures that cannot heal properly without surgical intervention, often requiring stabilization with screws, plates, or wires;
• carpal tunnel syndrome – this condition, which involves compression of the median nerve in the wrist, may require surgical release when conservative treatment proves ineffective;
• Dupuytren's disease – in advanced cases of this disease, where there is significant contracture of the fingers, surgery may be necessary to improve the mobility and functionality of the hand;
• Radial bone hypoplasia – also known as radial hemimelia, this is a congenital defect where the radial bone is partially or completely undeveloped. This not only causes the hand to be deformed, but also limits its functionality. Treatment often requires complex reconstructive surgery, which may include bone lengthening, corrective osteotomy, and ulnarization to improve the function and appearance of the hand.
• Congenital hand defects in newborns – these are diverse and can vary in severity and impact on hand function. Diagnosis and treatment of congenital hand defects usually begins in the neonatal period and may include both surgical treatment and rehabilitation to maximize hand function. Each case requires individual assessment by a pediatric orthopedic specialist.
• Thumb hypoplasia is a congenital malformation in which the thumb is abnormally shaped or too small. The degree of hypoplasia can vary from slight underdevelopment to complete absence of the thumb. Thumb surgery may include procedures such as polysynthesis and other operations aimed at reconstructing and strengthening the thumb to provide the patient with better hand function.

Each of these situations requires an individual approach and a thorough assessment by a specialist to ensure the best possible treatment and rehabilitation results for the patient. Hand surgery must therefore be well planned and performed by an experienced team of surgeons who are familiar with the latest surgical techniques and methods.

Hand surgery – surgical methods used

Hand surgeries can be complex and varied, depending on the type of injury or defect. Therefore, surgical methods are carefully tailored to the patient's needs. In the context of hand surgery, finger reconstruction after amputation, polysynthesis, and ulnarization deserve special attention.

Reconstruction of fingers after amputation

Finger reconstruction after amputation is a process that aims to restore as much functionality as possible to lost fingers. This may involve several techniques:

• Skin grafts – restore skin coverage at the site of amputation.
• Bone grafts – enable the reconstruction of the bone structure of the finger.
• Use of prostheses – which can be either temporary or permanent, depending on the situation.
• Microsurgery is a technique used to reconstruct a child's hand, which allows part of the limb to be saved using microscopic instruments to connect blood vessels and nerves.

What is politicization?

Finger reconstruction is a surgical technique used mainly in children who were born without a thumb or with a severely damaged thumb. The procedure involves transforming one of the fingers—usually the index finger—into a new thumb. This finger surgery involves moving muscles, tendons, nerves, blood vessels, and bones so that the newly created thumb can function like a natural one. This gives the patient greater ability to grasp and manipulate objects.

What is ulnarization?

Ulnarization is a technique in which the hand is moved to the ulnar side of the ulna. This procedure can be used in cases of radial bone hypoplasia. The main goal of ulnarization is to improve hand function by creating a new position that allows for better use of the remaining elements of the hand. The method of wrist ulnarization was developed by Dr. Paley.

Summary

Hand surgery is evolving into a key area of medicine that is of great importance for improving patients' quality of life. Although complex, these operations offer new opportunities for patients with difficult-to-treat hand defects, paving the way for a better and more independent life. However, it is important to remember that every surgical intervention requires careful planning, an experienced medical team, and intensive rehabilitation to maximize the chances of success and minimize the risk of complications.
