Z-plasty is a plastic surgery technique that is used to improve the functional and cosmetic appearance of scars. With this technique, it is possible to redirect a scar into better alignment with a natural skin fold or the lines of least skin tension.

Contracted scars may be lengthened with this technique. Z-plasty involves the creation of two triangular flaps of equal dimension that are then transposed. Basic z-plasty flaps are created using an angle of 60 degrees on each side, which can lengthen a scar by 50 to 70 percent and reorient the direction of the central wound by 90 degrees. Keeping the length and angle of each flap precisely the same is key to avoiding mismatched flaps that may be difficult to close.

Some possible complications of z-plasty include flap necrosis, hematoma formation under the flaps, wound infection, trapdoor effect, and sloughing of the flap caused by high wound tension. Z-plasty is a plastic surgery technique used to improve the functional and cosmetic appearance of scars.

It involves the creation of two triangular flaps of equal dimension that are then transposed. For a basic z-plasty, the triangular flaps are created using an angle of 60 degrees Figures 1a through 1e. Theoretically, this angle can lengthen a contracted scar by about 75 percent and reorient the direction of the central wound by 90 degrees. In practice, the lengthening and reorientation will be less, owing to increased wound tension. The basic degree z-plasty technique.

The original defect is 90 degrees perpendicular to the lines of least skin tension. Tension on the healing wound eventually widens and thickens the scar. The scar length AB is 2.

The diagonal lines should be the same length as the scar 2. The new flap tips are E and F. Angles smaller than 60 degrees are easier to transpose but result in less lengthening and realignment of the scar to less than 90 degrees. Angles larger than 60 degrees should be avoided because the force required to transpose the flaps increases markedly, making closure of the wound difficult.

The length of each of the lateral limbs of the z-plasty must be precisely equal to the central incision over the original scar, or puckering at the corners will result, and additional undermining and trimming of the flaps will be necessary to obtain proper closure. The multiple variations of the basic z-plasty are beyond the scope of this article. Incisions are made vertically through the skin using a no. The triangular flaps and the surrounding skin are undermined.

In a primary care setting, z-plasty is reserved for improvement of linear, thin scars and is not used as a primary closure technique. The most common situation in which a z-plasty would be used is an unfavorable cosmetic or functional scar that has not improved after waiting for a reasonable length of remodeling time e. More complicated scar situations, such as burn scar contractures, wide scar contractures on fingers, and hypertrophic or keloid scars, typically involve plastic surgery techniques other than basic z-plasty.


The F flap is pulled above the E flap.In vertebroplasty, bone cement is injected into fractured vertebrae to stabilize the spine and relieve pain. Vertebroplasty is an outpatient procedure for stabilizing compression fractures in the spine. Bone cement is injected into back bones vertebrae that have cracked or broken, often because of osteoporosis.

The cement hardens, stabilizing the fractures and supporting your spine. For people with severe, disabling pain caused by a compression fracture, vertebroplasty can relieve pain, increase mobility and reduce the use of pain medication. Kyphoplasty is similar to vertebroplasty, but uses special balloons to create spaces within the vertebra that are then filled with bone cement.

Kyphoplasty can correct spinal deformity and restore lost height. Vertebroplasty care at Mayo Clinic. Mayo Clinic does not endorse companies or products.

You lie face down on a table. The health care provider cleans the area of your back and applies medicine to numb the area. A needle is placed through the skin and into the spine bone. Real-time x-ray images are used to guide the doctor to the correct area in your lower back.

A balloon is placed through the needle, into the bone, and then inflated.


This restores the height of the vertebrae. Cement is then injected into the space to make sure it does not collapse again. A common cause of compression fractures of the spine is thinning of your bones, or osteoporosis. Your provider may recommend this procedure if you have severe and disabling pain for 2 months or more that does not get better with bed rest, pain medicines, and physical therapy.

Your provider may also recommend this procedure if you have a painful compression fracture of the spine due to:. You will probably go home on the same day of the surgery. You should not drive, unless your provider says it is OK. People who have kyphoplasty often have less pain and a better quality of life after the surgery.

They often need fewer pain medicines, and can move better than before. Randomized controlled trial of vertebroplasty versus kyphoplasty in the treatment of vertebral compression fractures.

Medical browser? Full browser?Urethroplasty is the repair of an injury or defect within the walls of the urethra. Urethroplasty is regarded as the gold standard treatment for urethral strictures and offers better outcomes in terms of recurrence rates than dilatations and urethrotomies.

The Basic Z-Plasty

It is probably the only useful modality of treatment for long and complex strictures though recurrence rates are higher for this difficult treatment group. There are four commonly used types of urethroplasty performed; anastomotic, buccal mucosal onlay graft, scrotal or penile island flap graftand Johansen's urethroplasty. With an average operating room time of between three and eight hours, urethroplasty is not considered a minor operation. Hospital stays of two or three days duration are the average.

More complex procedures may require a hospitalization of seven to ten days. Ideally, the patient will have undergone urethrography to visualize the positioning and length of the defect. The patient will be transported to the operating room and the procedures for induction of the type of anesthesia chosen by both the patient and medical staff will be started.

The subject area will be prepped by shaving, application of an antiseptic wash usually povidone iodine or chlorhexidine gluconate - if sensitive or allergic to the formersurgically draped and placed in the Lloyd-Davies position. Note: throughout the duration of the procedure, the patient's legs will be massaged and manipulated at predetermined intervals in an attempt to prevent compartment syndromea complication from circulatory and nerve compression resultant from the lithotomy positioning.

Some hospitals utilize the Allen Medical Stirrup System, which automatically inflates a compression sleeve applied to the thigh-portion of the stirrup device at predetermined intervals. This system is designed to prevent compartment syndrome in surgeries lasting more than six hours. At this time the surgical team will perform testing to determine if the anesthesia has taken effect.

Upon satisfactory finding sa suprapubic catheter with drainage system will be inserted into the urinary bladder to create urinary diversion during the procedureand the chosen procedure will then be initiated. Note: The surgical procedures listed below may have small variances in the methodology used from surgeon to surgeon. Consider the following as a generalized description of each individual procedure, although every precaution was taken to ensure the accuracy of the information.

The choice of procedure is dependent on factors including: [2]. Note: in more complex cases, more than one type of procedure may be performed, especially where longer strictures exist. In this single-stage procedure the urethra will be visualized in the area of the defectand the incision will be started at its mid-line usually using a bovie knife to dissect the dermal and sub-dermal layers until the associated musculature, corpus cavernosumcorpus spongiosumand ventral urethral aspects are exposed.

Particular care is used during the dissection to prevent damage to nerves and blood vessels which could result in erectile dysfunction or loss of tactile sensation of the penis. The area of the defect is evaluated and marked both mid-line laterallyand at the distal and proximal borders transversely. Using an index finger, the urethra is gently separated from the cavernosum, and a specially designed retractor is then placed behind the urethra to protect vulnerable areas from damage during the transecting and removal of the urethral defect.

The now patent ends of the urethra are prepared using a technique called "spatulation", which essentially allows for the end-to-end anastomosis to adjust to the differing diameters of the urethra. A silicone catheter is inserted through the penis and temporary distal-urethral end, and threaded into the temporary proximal-urethral end, leaving a wide loop for the surgeon to have access to the dorsal urethral aspect for micro-suturing, and start of the anastomosis.

The dorsal one-third of the urethral anastomosis is begun, completed, and the catheter is retracted slightly to allow for its positioning within the pre-anastomosed urethra. At this time, using micro surgical technique, the anastomosis is completed and fibrin glue is applied to the anastomotic suture line to help prevent leakage and fistula formation. The silicone guide catheter will then be withdrawn from the penis and a replaced by an appropriately sized Foley catheter and urinary drainage systemand the incision closed layer by layer.

Micro-doppler circulatory measurement of the penile vasculature is performed at way points throughout the procedure, and a final assessment is taken and recorded. The incision is inspected and dressed, and the patient is discharged to recovery. The area of the defect is evaluated and marked laterally mid-line, and marked positioning sutures are positioned one, each at the proximal and distal ends of the area of urethra closest to border of the defective area.

Upon retrieval, the buccal graft is presented to the urethral surgeon, who will then prepare the graft by trimming and removal of extraneous tissue. The surgeon will create an incised opening laterally between the known outer borders of the defect, retract the incised opening to the desired diameter, and position the graft to cover the incision.

Using micro surgical techniques, the buccal graft will be sutured in place and fibrin glue applied to the suture line to prevent leakage and formation of a fistula. At this time an appropriately sized a Foley catheter will be inserted through the repair and into the bladder and connected to a urinary drainage systemand the incision closed layer by layer.
