Bunionectomy

Overall Purpose of Procedure:• The common bunion is a localized area of enlargement

of the inner portion of the joint at the base of the big toe. The enlargement actually represents additional bone formation, often in combination with a misalignment of the big toe. The normal position of the big toe (straight forward) becomes outward-directed toward the smaller toes (Hallux Valgus.) The enlarged joint at the base of the big toe (the first metatarsophalangeal joint) can become inflamed with redness, tenderness, and pain. A small fluid-filled sac (bursa) adjacent to the joint can also become inflamed (bursitis) leading to additional swelling, redness, and pain.

Bunionectomy

Bunions are most often caused by an inherited faulty mechanical structure of the foot. It is not the bunion itself that is inherited, but certain foot types that make a person prone to developing a bunion.

Although wearing shoes that crowd the toes won't actually cause bunions in the first place, it sometimes makes the deformity get progressively worse.

Bunionectomy - Approaches Austin Bunionectomy: This is the most common type of

bunionectomy involving cutting the first metatarsal bone at the "head" and fixing the cut with a screw. There are other names for this type of bunionectomy including tricorrectional, chevron, etc. Typically, patients are able to put some weight on the heel of the operated foot immediately post-operatively.

Lapidus Fusion: This procedure is typically reserved for the more severe bunions and involves fusing the first metatarsal bone to the medial cuneiform bone. Recovery from this surgery is much more prolonged, requiring strict non-weight bearing with a cast for 6-8 weeks after surgery.

Fusion (arthrodesis) of big toe joint: Fusion of the

bunion joint is for severe osteoarthritis.

Bunionectomy - Approaches

McBride Bunionectomy: removal of bone and repositioning of tendons.

Keller Bunionectomy: Removal of part of the big toe joint. This procedure is performed mostly in older patients.

Silver Bunionectomy: Simple shaving of the bunion "bump." This procedure can only be done in minor bunion cases.

Bunionectomy

• A less common bunion is located at the joint at the base of the smallest (fifth) toe. This bunion is sometimes referred to as a tailor's bunion.

Bunionectomy

Define the procedure: • A dorsal incision is

made from the proximal phalanx to beyond the neck of the metatarsal.

• Removal of excess bone and realign the great toe.

Hammer Toe


Hammer Toe

• Overall Purpose of Procedure:• A hammer toe is a deformity of the second, third,

or fourth toe causing it to be permanently bent at the proximal interphalangeal joint, resembling a hammer. Mallet toe is another name for this condition when affecting the distal interphalangeal joint.

Hammer Toe- Anatomy -

• A Flexible Joint• You can straighten a flexible hammer toe with your

fingers. Although they look painful, flexible hammer toes may not hurt.

• A Rigid Joint• A rigid hammer toe cannot be moved, even with the

fingers. Rigid joints may cause pain and distort foot movement. This may put extra stress on the ball of the foot, causing a callus (a corn on the bottom of the foot).

• Exploration and Isolation:• Apply plantar pressure.• Senns or single tooth skin hooks.


• Surgical Repair• The long extensor muscle,

called the extensor digitorum longus (EDL), originates in the anterior leg. The EDL descends the leg crossing the ankle and continuing on to the tips of the toes. The EDL extends or lift the toes.

• Excision of the EDL.• Resection of the

articulating joint with a small saw.

• The edges of the joint are lined up and a k-wire is run through the end of the toe, fusing the joint.

• Reattachment of the EDL with suture like Supramid.

ORIF Ankle


ORIF ANKLE- ANATOMY -

ORIF ANKLE- ANATOMY - The leg bones form a scooped pocket

around the top of the anklebone. This lets the foot bend up and down.

Right below the ankle joint is another joint (subtalar), where the anklebone connects to the heel bone (calcaneus). This joint enables the foot to rock from side to side. Three sets of fibrous tissues connect the bones and provide stability to both joints. The knobby bumps you can feel on either side of your ankle are the very ends of the lower leg bones. The bump on the outside of the ankle (lateral malleolus) is part of the fibula; the smaller bump on the inside of the ankle (medial malleolus) is part of the tibia.

ORIF ANKLE

Overall Purpose of Procedure: To stabilize the ankle so the patient can regain function of their foot.

Define the procedure: The replacement of

the bones into their correct position via plate and screws to stabilize the ankle.

Open reduction and internal fixation of bimalleolar fracture

ORIF ANKLE BIMALLEOLAR fracture: means that

the lateral malleolus and the medial malleolus are broken.

Trimalleolar fracture: a fracture of the ankle that involves the lateral malleolus, medial malleolus and the distal posterior aspect of the tibia, the posterior malleolus. Strictly speaking, there are only two malleoli (medial and lateral), but the term trimalleolar is used nevertheless.

ORIF ANKLE-UNIMALLEOLAR-

Incision: 15 kb on #3 handle for incision.

Bone most often broken is the fibula.

Some surgeons like multiple 15 kb’s for this procedure. Be prepared for this. (bone dulls KB’s quickly)

incision can be made over the fibula with a ten blade as well as the tibia.

ORIF ANKLE CONT. OPERATIVE SEQUENCE

Hemostasis: Handheld Bovie and hemostats.a pneumatic thigh tourniquet is used for

hemostasis


Dissection and Exposure:

Metz, Adsons. Small Weitlander Senn Rakes


Exploration and Isolation:

periosteum is reflected with use of a periosteal elevator at the fracture site of the fibula/tibia


Surgical Repair/Removal/Specimen Collection:

Fibular fracture is manually reduced and maintained with the use of a bone clamp, the C-arm is utilized to view the reduction.

K-wire can be inserted through the fracture site and utilized as a guide wire or to hold the fracture together while proper plate is found.

CANCELLOUS SCREW VS CORTICAL SCREWS Cancellous screw: A screw designed for

placement in cancellous bone. The pullout strength of a screw is proportional to the amount of metal-bone contact. Because cancellous bone is porous, threads for cancellous bone screws have to be longer than for cortical screws to achieve the same degree of metal-bone contact and thus have the same pullout strength as cortical screws.

CORTICAL SCREW Cortical Screw:

Cortical screws have closely-spaced, shallow threads.

Cortical screws are stronger than cancellous screws of the same outer diameter.

FULL VS PARTIAL THREAD

SCREW PROCEDURE Drill Depth Gauge Tap Screw


Surgical Repair / Removal/Specimen Collection: A cannulated interfrag

cortical screw can be inserted perpendicular to the fracture site of the fibula (over the K-wire)

A 1/3 tubular plate (most common plate) can be bent to the shape of the fibula, placed over the fracture and stabilized with the screws.

The C-arm will again be utilized to check placement of screws and plate.


Hemostasis and Irrigation:All bleeding is controlled with cautery. Use of warm Saline to irrigate.Take emeses pan with you.


Closure:Subcutaneous tissue will be reapproximated

and sutured with use of 2-0 Vicryl. The skin will be closed with staples or

Monocryl.Patient to maintain strict non-weight

bearing status of the extremity.

REMEMBER Three simple steps to remember when

working with fractures:

Find the bone (fracture site) Reduce the bone Plate the bone
