4 By order of the Federal Agency for Technical Regulation and Metrology dated December 13
2011 Ne 1258-st interstate standard GOST ISO 5836-2011 was put into effect as a national standard of the Russian
Federation on January 1, 2013.

5 This standard is identical to the international standard ISO 5836:1988 Implants for surgery - Metal bone plates
- Holes corresponding to screws with asymmetrical thread and spherical under-surface base surface).

The degree of conformity is identical (YUT).

Information on the compliance of interstate standards with reference international
standards are given in the additional appendix YES.
The standard has been prepared based on the application of GOST R ISO 5836-2006

6 INTRODUCED FOR THE FIRST TIME

Information on the entry into force (termination) of this standard

published in the index "National Standards".
Information about changes to the current standard is published in the index
"National Standards", and the text of the changes - in the information signs "National
standards." In the event of a revision or cancellation of the current standard, the relevant
information will be published in the information index "National Standards"

1 Scope and distribution

This International Standard specifies dimensions and tolerances for openings.

in metal plates for fastening bone fragments used in

as implants in surgery in order to facilitate the correct

fixing of applied screws in accordance with ISO 5835.

Notes

1 This standard does not apply to the shape and dimensions of plates or
distance (center to center) between holes.
2 Relationship between international standards for screws and metal plates
for fastening bone fragments and the necessary tools for this is given in
appendix A.

2 Normative references

This standard uses the normative reference to the following

international standard:
ISO 5835:1991 Implants for surgery; metal bone screws with hexagonal drive
connection, spherical under-surface of head, asymmetrical thread; dimensions
(Implants for surgery. Metal screws for fastening bone fragments with
socket wrench. Spherical bearing surface of the head.

refer to a plate of thickness a/ cf. If the thickness of the plate exceeds a t, the value of t should not exceed that given in Table 1 so that the plate does not
weaken. In this case, the value of size b should increase. If the thickness of the plate is less than a<. the value of dimension b should not be less than that presented
in table 1 in order to prevent the protrusion of the screw head above the surface of the plate. In this case, the value of the size t must be reduced and may reach zero.

All of the above is represented by mathematical conditions.

Annex A
(reference)

Relationship between international standards for screws and metal plates

for fastening bone fragments and the necessary tools for this

A series of international standards for screws and metal plates for

fastening of bone fragments and the tools necessary for this is divided into two
parallel series. The reason was the big difference in the shape of the thread
screws for fastening bone fragments (types of screws HA and HB are opposed
screw types HC and HD).
Diagram illustrating the relationship between screws, plates and
tool included in two parallel series of international standards,

is given in Table A.1.
