Investing stitch suture pattern dog

These factors have also been shown to be associated with an increase in gliding resistance. However, after the healing process is completed, the tendon remains less homogeneous in comparison with the unaffected tendon for long periods and nonabsorbable suture material remains visible as hyperechoic foci.

The patient had no history of lameness in the affected limb prior to this event. At the time of admission, the dog was able to ambulate with a plantigrade stance. A deep skin laceration in the region of the common calcaneal tendon was observed, and a complete transverse tendon laceration was suspected.

Orthogonal radiographs of the tarsal region revealed discontinuity of the opaque soft tissue margin of the calcaneal tendon with interspersed fat opacity. No bony abnormalities were identified. An acute, complete, transverse common calcaneal tendon laceration was diagnosed based on the clinical presentation, physical examination, and radiographic findings. A preoperative complete blood count and serum biochemical profile were within normal limits.

It contains many hair follicles with multiple shafts of fine dense hair. Removing the hair without damaging the skin or clogging the clipper blades can be difficult. A good-quality, robust set of clippers is a sound investment. Rabbit hair is so fine that it quickly becomes trapped between fine clipper blades. Running the clipper blade slowly through the fur can prevent this. Depilatory creams can be used but tend to be messy and difficult to clean off satisfactorily.

The application of excessive quantities of spirit to the operation site can cause heat loss, especially in small, thin rabbits.

Apposing sutures bring the tissue edges into direct contact without eversion or inversion. Another differentiation in suture patterns is whether they are a simple or mattress tension suture: Mattress patterns: Close an incision under tension better than simple patterns.

May slow down healing by compressing tissue on each side of the incision, compromising local blood supply. Designed to withstand more tension by spreading the tension over a wider area. May be appositional, inverting, or everting depending on whether suture material is placed full or partial thickness within the skin edge.

Suture knots There are some guiding principles of knot formation that should be followed: Knots should be as small as possible to minimize foreign body reactions. After the first loop is tied in a knot traction should be maintained to avoid loosening.

Extra knots do not add strength to an accurately tied knot. Useful knots to learn: Aberdeen knot: the Aberdeen knot has been shown to be stronger and more secure than a surgeon's knot for ending a suture line. The Aberdeen knot is also of a smaller volume than a standard surgeon's knot. An Aberdeen knot tied with 3 throws and 2 turns has been shown to provide the maximum level of security.

Sliding knot: useful for placing a ligature deep in a body cavity, it should always be covered with a square knot for security to prevent the knot loosening. Fascial imbrication. The technique is essentially the same as for a vertical mattress suture except that two sutures are placed in a parallel fashion before they are tied. This produces an interrupted pattern in which the edges of the wound are inverted.

Usages Second layer of closure for hollow viscera. Two-layer closure is historically utilized to aseptically invert a transected, clamped viscus. A single layer of Cushings sewn over a clamp and tightened as the clamp is removed. Followed by an inverting seromuscular pattern Oversewn with Lembert. Usages Closure of hollow viscera stumps. A bite is taken at regular intervals around the perimeter of an opening so that when pulled tight, it can be made smaller or closed completely.

This technique may be used to close visceral stumps and to secure percutaneous tubes into a viscus such as may be seen in gastrostomy and cystostomy procedures. Useful for areas such as the rectum to correct a prolapse. Usages Closure of hollow viscera stumps or securing of tubes and catheters. Tension Sutures 1. Interrupted Horizontal Mattress Suture Common Suture Patterns: Interrupted Horizontal Mattress The needle is passed from one side of the wound to the other 2—5 mm away from the wound edge , then horizontally back across the wound, leaving a short gap 6—8 mm between the bites.

This creates a horizontal suture on either side of the wound. A knot is then placed to join the suture material on the original side. This suture is mostly used for relieving tension. Appositional to everting suture pattern depending on the tightness of throws. Can strangulate blood. Usages Closure in areas of high tension or occasionally used in the closure of flat tendons or muscle with minimal fascia vessels at wound edges.

Interrupted Vertical Mattress Suture Common Suture Patterns: Interrupted Vertical Mattress A bite is taken 8—10 mm away from the wound and passes through to an equal distance away from the wound on the opposite side. The suture is then repeated back across the wound, but this time, a bite is taken vertically from the original bite 3—4 mm away from the wound, creating a vertical suture on either side.
