RU2342913C1 - Method of preventive measures of deformation and fracture of patients with metabolic osteopathy and osteogenesis imperfecta - Google Patents

Abstract

FIELD: medicine, traumatology, orphopedics.

SUBSTANCE: invention can be used as preventive measures for fractures and further deformation of bones of patients with metabolic osteopathy and osteogenesis imperfecta. Bones of limbs are preventively armored by archwise curved spokes with hydroxyapatite cover, note that tips of the curve of the spokes are oriented to the opposite directions when they inserted to medullary canal.

EFFECT: strained elastic system preventing from limbs deformation.

Description

The invention relates to medicine, in particular to orthopedics, and can be used to prevent deformations and fractures of long tubular bones in patients with metabolic osteopathies and imperfect osteogenesis.

A known method for correcting bone metabolism is based on the integrated administration of xidiphon and oxydevitis drugs into the patient’s body according to the following scheme: 2 months — admission, 1 month — break during treatment for the first two years and two monthly courses per year with a treatment duration of more than two years ( Patent 2029550 RF, publ. 1995.02.27).

However, this method is intended for a long course of treatment, leading to a decrease in the risk of new fractures, but does not completely prevent them.

There is a method of treating the prevention of deformities and fractures in patients with metabolic osteopathies and imperfect osteogenesis, which includes the use of high doses of vitamin D with calcium and phosphorus preparations in combination with bed rest, therapeutic massage and spa treatment (P.V. Novikov “Rickets and hereditary rickets-like diseases in children: diagnosis, treatment, prevention. ”- M., Triada-X, 2006, 336 p).

However, this method of treatment often leads to severe forms of bone deformities or fractures of the tubular bones, and when surgical treatment with corrective osteotomy of the tubular bones of the lower legs or thigh bones with correction of the axes of the lower legs and thigh, and further immobilization with a plaster cast or distraction compression apparatus.

The objective of the invention is the prevention of deformities and fractures of limb bones in patients with metabolic osteopathies and imperfect osteogenesis, which prevents the development of deformities, fractures and pain relief in these diseases.

This problem is solved by the fact that in the method for the prevention of deformities and fractures of limb bones in patients with metabolic osteopathy and imperfect osteogenesis, including drug therapy, reinforcement of the bones of the limbs is performed by arcuately curved knitting needles with a hydroxyapatite coating, and the bend vertices of the knitting needles when they are inserted into the bone marrow Orient in opposite directions.

The proposed method is illustrated by a description, an example of practical use and illustrative material, which shows:

Figure 1 - X-ray diffraction patterns of the right and left limbs of the patient M., 40 years old, before treatment;

Figure 2 - X-ray diffraction patterns of the right and left limbs of the patient M., 40 years old, after intramedullary reinforcement.

The method is as follows.

During the operation, two channels are initially formed in an oblique direction to the diaphysis of the bone at the levels of the proximal and distal metaphyses so that they end in the bone marrow cavity. Then, arched curved spokes are introduced into each of the formed channels, and the vertices of the bending of the spokes are oriented in opposite directions when they are introduced into the marrow canal. Knitting needles bite and sink deep into the soft tissues.

The practical use of the method is illustrated by the following clinical example.

Patient M., 40 years old, medical history No. 27178, diagnosis: phosphate diabetes; valgus deformity of the right lower limb, varus deformity of the left lower limb, shortening of the right lower limb 2 cm (Figure 1).

To prevent further deformation and fractures, an operation was performed: preventive reinforcement of the femur and tibia with spokes with a hydroxyapatite coating.

After anesthesia and treatment of the surgical field, two canals were formed in the fragments of the femur and tibia using well-known techniques. Then they entered through them to the opposite metadiaphysis along an arcuately curved spoke. The bend vertices of the spokes introduced into the bone marrow canal were oriented in opposite directions. The ends of the needles were bitten, bent and immersed in soft fabrics. The operation was completed by suturing wounds, applying aseptic dressings and performing control radiography. (Figure 2).

After a year at the control examination: the axis of the limb is correct. The patient leads an active lifestyle, there are no pain when walking.

Using the proposed method in the clinic FGUN "RRC" WTO "them. Acad. GA Ilizarova Roszdrav ”showed that its use in the treatment of patients with imperfect osteogenesis and metabolic osteopathy, accompanied by osteoporosis of bone tissue, provides a warning for the development of deformities. This effect is achieved due to the preventive reinforcement of the femur and tibia with hydroxyapatite-coated needles to create an intraosseous tensioned elastic system that counteracts limb deformation.

Claims (1)

A method for the prevention of fractures and the further development of deformity in patients with metabolic osteopathies and imperfect osteogenesis, characterized in that prophylactically reinforcing the bones of the limbs with arcuate curved spokes with a hydroxyapatite coating, the bending tips of the spokes being oriented into the marrow canal are oriented in opposite directions.
