Lag Screw Technique (Small and Large Fragment)

Lag screw is commonly used in orthopaedic surgery. Correct technique is imperative in order to get a good compression and stability at fracture site.
This video describes the lag screw technique in detail. After watching the video you will be able to put a lag screw using correct operative technique.

[@sanjaydhungana8242]

from where did you do your mbbs and md? and are these two degrees just sufficient to be a skilled orthopedic surgeon?

[@DrVinayKumarSingh]

It's all mentioned in the channel description.

[@gm2311902007]

Sir, wilL the screw size of large and small fragment be different in forearm bone and lower limb bone, say radius and femur.?

[@DrVinayKumarSingh]

It's already there.

[@sanjaydhungana8242]

more frequent videos please

[@DrVinayKumarSingh]

Sure

[@bmorthonanban1508]

Nice demonstration sir. Countersink is same for 3.5 and 4.5 or different?

[@DrVinayKumarSingh]

It's different as head size is different.

[@savjoshi]

Sir should tapping be extended till 2nd cortex?Or only in the gliding hole?

[@DrVinayKumarSingh]

Tap is needed only for pilot hole.

[@abid-ali1235]

Excellent demonstration sir...plz adv lag screw should be inserted in the last or it be the first screw, when we r doing plating

[@DrVinayKumarSingh]

Lag should be the first step

[@24khare]

Sir please make videos on basics screws and drill bits which one to use when...it's hard to remember every time in diffrent surgeries

[@DrVinayKumarSingh]

Hopefully soon.

[@vimalsyama]

Do we have to tap only for the gliding hole? How will a 4.5 mm or 3.5mm screw will go into the smaller size pilot hole?

[@DrVinayKumarSingh]

You need to read about screws.

[@akshaypushkar807]

Thank you Sir..
Nice demo..
Sometimes, we find it difficult to seat the plate after putting the lag screw. request if you can demonstrate Sir. Whether the neutralization plate (or even bridge plate) should be put orthogonal to lag screw or over the lag screw once its head is countersunk?

[@DrVinayKumarSingh]

Akshay you have few options as you mentioned in the question.
1. Seat screw after countersink so that it's not proud.
2. Put plate in a way that head if screw is in different plane like we do in fibula fracture around ankle.
3. Put lag screw through the plate.
If you use lag screws then your plate will be neutralisation mode not bridge mode.

[@akshaypushkar807]

Thank you Sir for your prompt response Sir.. It's crystal clear now sir..

[@arunlal3879]

sir does the order of steps matter? I mean is depth measuremnrt fol by tap and then countersink still the same?

[@DrVinayKumarSingh]

These are my steps

[@mrzackhan]

Sir please make videos about foot and ankle fractures and it's management 😊😊

[@lucasthechihuahua6332]

dear dr, I have a question, what is the countersink number for a 3.5mm screw and for a 4.5 screw, thanks

[@DrVinayKumarSingh]

They come as part of small and large fragment set

[@mohammadminhazuddin743]

thnks for doing good job in pandemic situation..which one is better? lag in the plate hole or lag directly on the bone? doing tab is necessary?

[@DrVinayKumarSingh]

Lag screw through the plate is much stronger than the screw on its own. Tap is needed if you are using a non tapping screw.

[@mohammadminhazuddin743]

in case of lag through the plate what is the sequence of screw?

[@DrVinayKumarSingh]

@@mohammadminhazuddin743 it's S3 except first step will be reduction and application of plate.

[@mohammadminhazuddin743]

@@DrVinayKumarSingh sir that means 1st lag then all screw in neutral hole..?

[@DrVinayKumarSingh]

@@mohammadminhazuddin743 that's correct else it will create compression and lag screw may come loose or fracture may displace.

[@sanjaydhungana8242]

sir, it's been 7 weeks post orif #SOH, can i do pushups now?

[@DrVinayKumarSingh]

No not before six months

[@vishwarewal4412]

Sir its difficult for me to get reduction many a time your opinion regarding how to hold nerve during such situations

[@DrVinayKumarSingh]

Patience and correct position of reduction claps to allow access for lag screw.

[@jeffertvmc]

Sir Can I know What company of 3.5 and 4.5 instrument set you are using?

[@DrVinayKumarSingh]

It's Indian made

[@drhomymodi5412]

Sir which screw size used as lag principle in small and large fragment fracture..? Is it 3.5 and 4.5..??

Yes
