Shark Screw®

Less: pain, risks, sick leave.9

Shark Screw®

the screw made from human bone

Shark Screw® is a screw made from human donor bone and is used in orthopaedics and trauma surgery. Like the body’s own bone, this bone screw undergoes natural, constant bone metabolism and is remodeled within a few weeks or months into new, ideally adapted bone tissue.1,2 There is no need for an operation to remove the metal.2 Metals in the body, on the other hand, entail precisely this risk: in many cases, they have to be removed again during a second operation. Otherwise, they remain in the body with no function.3,4 However, screws made from human bone have far more advantages than the elimination of metal removal.4

Advantages of Shark Screw®

No metal removal

“Shark Screw® is integrated into the natural bone remodeling process of the human body and becomes the patient’s own bone – my patients are spared the risks that metals can cause in the body.”

Natural material

“Shark Screw® is a screw made from pure human donor bone – a very safe material that is familiar to the human body.”

Excellent compatibility

“Our experience: Shark Screw® has proven its worth for many years in patients with or without pre-existing conditions. These include intolerances, allergies and diabetes. We provide our patients with Shark Screw® for hallux valgus and many other operations.”

Becomes your own bones

“The big advantage for my Shark Screw® patients: This screw is converted into the patient’s own bone. The screw is no longer visible on the X-ray image after a while.”

How bone healing works

From Shark Screw® to the patient’s own bone

After insertion into the bone, Shark Screw® is colonized by the body’s own cells and integrated into the natural bone metabolism. This natural integration process creates new bone connections.1 Possible complications that can arise from metals in the body, such as irritation of nerves, ligaments and tendons, are therefore eliminated. The avoidance of these risks, sick leave and time expenditure leads to enormous savings in the healthcare system. 3,4,5

Patients' experiences

Real people – real stories. How are patients who have been treated with Shark Screw® doing today? Why did they choose Shark Screw®? Here you will find selected experiences of patients who have been treated with Shark Screw®.

Magdalena's story

Severe bunion

“My bunion made it difficult for me to buy shoes and do sports. It was made clear to me that if I had a metal plate fitted, it would have to be removed again later – I wanted to avoid this additional second surgery. That’s why I opted for Shark Screw®. I am extremely happy with the result and I am very pleased every day when I see my foot. I am grateful that I can now do any sport again and that I can find shoes that fit again.”

Raphael's story

Flatfoot

“At first I didn’t even know I had flat feet when the pain in my foot started. I was particularly restricted by this deformity when walking. My orthopaedist told me about the Shark Screw® and my decision was made straight away – I don’t want to have any metal in my body. It also saves me a possible second surgery to remove the metal.”

Ilse's story

TMT ll-lll

“At first, I had the feeling that my feet were always falling asleep – a short time later, the pain from the osteoarthritis got worse and worse when I walked. It even affected my spine. Unfortunately, painkillers no longer helped, so I decided to have surgery. I opted for Shark Screw® because it saved me a second surgery to remove the metal.”
