How To Tell If You Are Lost Eah
The fiber orientation of the muscles will guide you to them. The brachioradialis runs from proximal to the elbow in a straight line toward the radial styloid, whether the elbow is flexed or extended. With the elbow flexed, the tendons of the brachialis and biceps will be at a 60- or 70-degree angle, or perhaps greater, to the fiber direction of the brachioradialis. If you dissect too far proximally along the brachioradialis, you will not see the brachialis muscle well. You should, however, see...

The incision should be marked directly over the spinous processes. Frequent palpation of the bony landmarks is typically all that is needed to ensure a midline approach. A midline raphe between the cervical musculature provides an excellent avascular plane for dissection. If the exposure seems excessively bloody with extensive muscle bleeding, stopping and identifying this midline plane will reduce further blood loss. The C2 spinous process is typically large and bifid. The C3 process is often...

It is difficult to get lost because the bones are subcutaneous. If you see the extensor tendon of the first toe, you are too far lateral. If you see the toe flexor tendons, you are too far plantar. It is possible to be too proximal or too distal if your goal is to get to the metatarsophalangeal joint it is easily remedied by extending the incision.

As with many approaches, it is difficult to get lost when you are coming directly down on the bone. The key landmark is the medial border of the biceps. Once you have that retracted out of the way, then the neurovascular structures are medial and posterior to it and should be protected. The brachialis muscle, which is surprisingly big, underlies the biceps, and sometimes it is difficult to tell one from the other. It is not usually necessary to do so, however, and you can simply approach...
How To Tell If You Are Lost Dwv
Getting lost medially or laterally is fairly common with this approach because there are so many tendons in view. The main way to tell if you are too far to one side or the other is to grasp the tendon gently and pull on it and see what moves. That should give you an idea what structure you are looking at. It is no problem if you are too far one way or another. You simply come back to the midline and find what structure you are looking for. If you see an artery on either the medial or the ulnar...
Technique Rvf
Generally, a V-shaped zigzag incision is made through the skin and subcutaneous tissue. Once you are deep to that tissue, the intrinsic muscle tendons are easily identified. There is fascia in between the intrinsic muscle tendons and the central slip tendons, which when split will expose the proximal phalanx. In the middle phalanx, the intrinsic muscles have come together to form a tendon that goes on to the distal phalanx. By staying on either side of this tendon, you can expose the bone....

The medial knee approach, as seen in Figures 40 2 and 40 3, does not provide much in the way of visual cues as to where the various structures are. The major way to identify the location of the medial collateral ligament is by palpation. It is easy to feel the medial femoral condyle and the ligament as the thickening in the capsule. If you are too far proximal or distal and not centered over the joint line itself, you simply need to extend the incision. If you are too far anterior, you will see...

If the incision is too far dorsal, you will encounter the extensor pollicis longus EPL tendon. Pull on the tendon to determine its function. Sometimes the EPB will also cause thumb interphalangeal joint extension, so check where the tendon is located proximally as you pull on it. The EPL is seen just ulnar to Lister's tubercle, and the EPB is seen at the radial border of the anatomic snuffbox. You might also become lost in identifying the carpometacarpal joint. Remember that the basal joint is...
How To Tell If You Are Lost Dmy
This approach is based on the key landmark of the flexor carpi radialis FCR tendon. If you do not see the tendon, which is an easily identifiable structure, you are lost to one side or the other. If you are deep to the subcutaneous tissue and do not see any tendons, you are typically too far radial. If you go through the flexor retinaculum and see multiple tendons, you are too far ulnarward. This approach should not be carried deep until the FCR tendon is identified. You can clearly see the fat...

If you get lost in this approach, reconsider radiology. It is easy to get lost in the terminology, so here are a few definitions Eponychium The thin membrane of tissue extending from the nail wall for a short distance onto the nail. Hyponychium The mass of keratin beneath the distal nail just distal to the distal edge of the sterile matrix . Lunula The convex opaque portion of the proximal nail, corresponding to the underlying germinal matrix. Nail bed All of the soft tissue beneath the nail...
How To Tell If You Are Lost Cuv
It is easy to get confused as to which muscle is which with this approach because of the muscles' very large size and because they all tend to run together, especially proximally. If you are not seeing the adductor longus and brevis discretely with the anterior branch of the obturator nerve, then you are probably lost. Usually you would be lost anteriorly, which is a very dangerous situation, because if you are anterior to the pectineus the femoral neurovascular structures are very much at...

Once you have cut the flexor retinaculum proximal to the wrist, you should palpate the transverse carpal ligament with a hemostat or other similar blunt instrument and feel the grittiness of the transverse fibers. You should also feel the hook of the hamate from inside the carpal canal and then start your transection with the nerve protected. Once you are deep to the superficial fat and the palmar fascia, any further fat that is encountered distally indicates you are already distal to the end...

Tricks Ome
When incorporating traumatic wounds into this incision, a more acute angle may be necessary. If you are unable to create a zigzag pattern without creating a skin angle more acute than 60 degrees, then make a longitudinal extension of the traumatic wound to the level of the skin crease, and extend the incision diagonally across the crease. When raising flaps, use the scissors to bluntly dissect, by spreading in a longitudinal direction. This reduces the chance of injury to the digital nerve and...
Structures At Risk Sdt
Laterally, the structure at risk is the radial nerve. This nerve enters the forearm underneath the brachioradialis muscle, which is the first muscle identified with this approach. The anterior edge of that muscle should be dissected and the nerve will be found on the inner border of the muscle. It should be retracted out of the way and protected. The brachial artery and the median nerve are at risk if you are dissecting medial to the biceps tendon. As long as you stay lateral to those tendons,...
Tricks Qsp
This approach is straightforward, with no real tricks. There is no reason to separate the subcutaneous tissue from the skin generally, and it is better from a healing standpoint if they are incised as one layer. Once you are deep to the subcutaneous tissue, further dissection curves around the medial or lateral borders of the patella. As the incision approaches the tibial tubercle, it should veer either to the medial or lateral sides so it is not directly over the prominence of the tubercle.
