Department of Orthopedics, Teikyo University Hospital

Conditions Treated
Pseudoarthrosis and Malunion in Limb Healing from Trauma.

Treatment Methods (Surgical Operation of Malunion and Pseudoarthrosis Using Ilizarov Technique and Chipping Technique)

Most fractures steadily heal if appropriately treated. However, open fractures and splinter fractures, if they are difficult to treat or are improperly treated, may lead to complications such as bending stiffness and short limbs in fracture union (malunion) and delayed union

(pseudoarthrosis). These outcomes often make daily life difficult.

A bone lengthening procedure called the Ilizarov method is a method for treating such cases. In this method, part of the bone in the lesion is cut off, the gap in the bone is gradually extended to grow the bone as porosis develops, and finally the bone is fixed at an appropriate length.

However, this method is used by few medical facilities, including those overseas, because it requires precise techniques and much experience. The Department of Orthopedics of our hospital introduced the Ilizarov method at an early stage, and has since gained a solid experience and the best results in Japan.

The Department also offers a unique surgical operation that is an extension of the Ilizarov method. This method, called the chipping technique (fracturing method), does not cut off any bone but fractures some portions of the normal bone above and below a lesion to accelerate porosis. The Department has also been developing treatments that reduce the inconvenience for patients undergoing medical treatment. In the Ilizarov method, external fixators are used to extend bone gaps and to fix them, which have a wide external frame with a number of metal rings. The patients suffer greatly in daily life when wearing such external fixators for several months. To improve the situation, the Department has developed a new treatment procedure in which a unilateral external fixator is used to extend deformed bones and, after such bones are sufficiently extended, a six-legged ring-type frame (Taylor spatial frame) is used to press back the bones for quick correction. This technique requires the patients only to wear a unilateral external fixator most of the time during the treatment period, thus shortening the period and making daily life much easier. A large number of cases of non-union fractures have already been treated by this method.

Our hospital is founded on the principle of reliable, safe, advanced patient-oriented medical treatment, and continues to research and develop state-of-the-art medical treatments as a university-based hospital. Like other departments, the Department of Orthopedics offers a wide range of medical treatments beyond a specific field, with a variety of experts, and is particularly renowned for the treatment of non-union fractures. There are few hospitals in the world that specialize in the treatment of malunion and pseudoarthrosis; the Department of Orthopedics uses the latest techniques and treatment procedures focusing on the recovery of function as well as external appearance. Many of the patients who come to the hospital with such troubles have already undergone multiple surgical operations at other hospitals; we respect the requests of these patients and strive to meet them fully.

Moreover, in the Department of Microsurgery of the Hands, Professor Nagatsugu Kuroshima, one of the world’s leading microsurgeons, has attracted attention not only for his skill, but also for developing a high-performance surgical operation microscope in cooperation with an optical equipment manufacturer in Japan.

A Message to International Patients from Our Department

Dr. Masanori Fujimura
Dr. Takashi Matsushita
Head Professor and Department Chair

If you have experienced a serious accident and are concerned about malunion or pseudoarthrosis, please come and consult us. Do not try to convince yourself by saying “I can live with some difficulty; at least I’ m still alive.” Our mission is to resolve such worries. We take pride in being the fastest to correct malunion and pseudoarthrosis, no matter how serious it may be, with our unparalleled experience and technologies as long as there is no infection. We accept international patients, and provide the world’ s leading medical treatments in this field, including our unique procedures.

Overview of the Treatment Schedule
(Model Case: Treatment of Pseudoarthrosis and Angle Deformity of a Lower Limb)

You must send photos of both lower limbs (full-length external appearance and X-ray photos, from the front and sides) in advance for us to examine the possibility of admission.

Unfortunately, we cannot accept cases in which the patient has experienced an infection in the lesion, because the treatment period can be very long. Therefore, to determine admission, we need some information such as that you have never had any infection in the lesion or suppuration in the lesion.
