<h2>Equipement</h2> <ul> <li>30 deg, 4 mm arthroscope;</li> <li>arthroscopic pump;</li> </ul> <h2>Positioning</h2> <ul> <li>patient is usually prone with sandbag placed under antecubital fossa;</li> <li>TV monitor is positioned opposite of the patient;</li> <li>ulnar nerve is palpated to pinpoint its location and to ensure that it does not subluxate with elbow flexion</li> <li>instill fluid into the joint thru the <a href="/joints/aspiration-of-elbow-joint/" data-wpel-link="internal">aconeus triangle</a>; <ul> <li>through the lateral soft spot, which is bound by the radial head, lateral epicondyle, and olecranon</li> <li>when the elbow is distended, the major neurovascular structures are positioned farther away from the portal sites</li> </ul> </li> </ul> <h2>Portal Placement</h2> <h3><strong> posterolateral portal</strong></h3> <ul> <li>portal is located thru the center of the <a href="/joints/aspiration-of-elbow-joint/" data-wpel-link="internal">aconeus triangle</a>;</li> <li>when the anterior aspect of the joint is being visualized, the posterolateral portal can be used as an outflow portal;</li> <li>posterolateral portal can be used to visualize the posterior elbow structures including the olecranon fossa; <ul> <li>use of a 70 deg arthroscope facilitates visualization of the radiocapitellar joint;</li> </ul> </li> <li>this portal allows debridement of the capitellum (in the case of <a href="/joints/osteochondritis-of-the-elbow/" data-wpel-link="internal">osteochondritis dissecans</a>);</li> </ul> <h3>anterosuperior lateral</h3> <ul> <li>considered safer than anterolateral portal;</li> <li>portal allows visualization of the ulnohumeral articulation, anteromedial aspect of elbow, coronoid fossa and process, and anterior<br /> aspect of radiocapitellar joint;</li> <li>portal is placed 2 cm superior to the anterior aspect of lateral epicondyle;</li> <li>blunt dissection into the joint capsule helps to avoid injury.</li> </ul> <h4>cautions</h4> <ul> <li>PIN is most at risk, (less than the anterolateral portal) and lateral antebrachial cutaneous nerves are at risk;</li> </ul> <h3>anterolateral portal</h3> <ul> <li>this portal can be used for instrumentation as well as visualization of the lateral aspect of the radial head;</li> <li>this portal is often established first;</li> <li>w/ elbow flexed 90 deg, the portal is located 3 cm distal and 1-2 cm anterior to the lateral epicondyle, which should bring portal just anterior and proximal to the radial-capitellar articulation w/ the portal driven toward the center of the trochlea; <ul> <li>elbow is kept flexed during trochar insertion since extension brings the radial nerve closer to the joint (3 to 7 mm);</li> </ul> </li> </ul> <h4>hazards</h4> <ul> <li>the portal pass through the ECRB and supinator;</li> <li><a href="/nerves/posterior-interosseous-nerve/" data-wpel-link="internal">posterior interosseous nerve</a> is at risk w/ this portal, as it runs about 0.5 cm to 1 cm anterior and medial to the portal;</li> <li>in order to protect the PIN, this portal is made from inside outward under visualization from the proximal-medial portal;</li> <li>the scope is advanced anterolaterally across the radial head w/ care not to deviate too anteriorly;</li> <li>the light of the arthroscope will be visible thru the skin which will facilitate proper skin incision;</li> </ul> <h3>proximal anterolateral portal</h3> <ul> <li>located 2 cm proximal and 1 cm anterior to the lateral epicondyle;</li> <li>this portal is significantly farther (on average 13.7 mm) from the radial nerve than other anterolateral portal sites;</li> <li>this portal allows for an excellent view of the anterior radiohumeral and ulnohumeral joints as well as the anterior capsular margin.</li> </ul> <h3>proximal antero-medial portal</h3> <ul> <li>allows visualization of the following: <ul> <li>anterior elbow including the anterior joint capsule, medial condyle, coronoid process, trochlea, capitellum, and the radial head;</li> <li>radial head is best visualized from the proximal anteromedial portal</li> </ul> </li> <li>joint should already be distened w/ fluid;</li> <li>location is 2 cm proximal to medial epicondyle, and immediately anterior to the inter-muscular septum, using a longitudinal skin stab incision;</li> <li>ensure that the position of the intermusuclar septum is clearly demarcated;</li> <li>make 1/2 cm incision and spread w/ hemostat;</li> <li>trochar is inserted over the anterior surface of the humerus aiming for the radial head;</li> <li>maintain contact w/ anterior humerus at all times to reduce risk to N/V structures is minimized.</li> <li>trocar w/ it (arthroscopic sheath) is then inserted, followed by the scope;</li> <li>hazards: <ul> <li>nerves at risk w/ this portal include the <a href="/nerves/ulnar-nerve/" data-wpel-link="internal">ulnar nerve</a>, medial brachial cutaneous, <a href="/nerves/medial-antebrachial-cutaneous-nerve/" data-wpel-link="internal">medial antebrachial cutaneous</a>, median nerve, and brachial artery;</li> <li>ulnar nerve lies 4 mm from this portal site;</li> <li>median nerve lies 7-20 mm away from portal with the elbow in flexion;</li> </ul> </li> </ul> <h3>anteromedial portal</h3> <ul> <li>some surgeons prefer to establish this portal first;</li> <li>elbow should be flexed 90 deg as the portal is established;</li> <li>placed 2 cm anterior and 2 cm distal to the medial epicondyle, placed under direct vision;</li> <li>the <a href="/nerves/median-nerve/" data-wpel-link="internal">median nerve</a> lies 1 to 2 cm anterior and lateral to this portal;</li> </ul> <h2>Complications: nerve damage</h2> <ul> <li>be particularly careful in elbow that have altered anatomy or scarring (as from intra-articular fracture); <ul> <li>this situation may distort normal landmarks, decrease arthroscopic distension, and cause nerves to remain adherent to capsule;</li> </ul> </li> <li>in the report by <a href="http://www.ncbi.nlm.nih.gov/pubmed/11205854" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">Kelly EW, et al<span class="wpel-icon wpel-image wpel-icon-6"></span></a>, the authors retrospective review of 473 consecutive elbow arthroscopies performed in 449 patients over an 18 year period was conducted; <ul> <li>of the 473 cases, 414 were followed for more than six weeks;</li> <li>most common final diagnoses were osteoarthritis (150 cases), loose bodies (112), and RA or inflammatory arthritis (seventy-five);</li> <li>arthroscopic procedures included synovectomy (184), d茅bridement of joint surfaces or adhesions (180), excision of osteophytes (164), diagnostic arthroscopy (154), loose-body removal (144), and capsular procedures such as capsular release, capsulotomy, and capsulectomy (73).</li> <li>a serious complication (a joint space infection) occurred after four (0.8%) of the arthroscopic procedures;</li> <li>minor complications occurred after fifty (11%) of the arthroscopic procedures; <ul> <li>these complications included prolonged drainage from or superficial infection at a portal site after 33 procedures, persistent minor contracture of 20掳 or less after seven, and twelve transient nerve palsies (five ulnar palsies,<br /> four聽superficial聽radial palsies, one posterior interosseous palsy, one medial antebrachial cutaneous palsy, and one<br /> anterior interosseous palsy) in ten patients;</li> <li>most significant risk factors for the development of a temporary nerve palsy were an underlying diagnosis of rheumatoid arthritis (p < 0.001) and a contracture (p < 0.05). There were no permanent neurovascular injuries, hematomas, or<br /> compartment syndromes in our series, and all of the minor complications, except for the minor contractures,聽resolved<br /> without sequelae.</li> </ul> </li> </ul> </li> <li>references: <ul> <li><a href="http://www.ncbi.nlm.nih.gov/pubmed/11205854" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">Complications of Elbow Arthroscopy<span class="wpel-icon wpel-image wpel-icon-6"></span></a>.</li> <li><a href="http://www.ncbi.nlm.nih.gov/pubmed/10524831" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">Complete Transection of the Median and Radial Nerves During Arthroscopic Release of Post-traumatic Elbow Contracture<span class="wpel-icon wpel-image wpel-icon-6"></span></a>.</li> <li><a href="http://www.ncbi.nlm.nih.gov/pubmed/25957982" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">The course of the median and radial nerve across the elbow: an anatomic study<span class="wpel-icon wpel-image wpel-icon-6"></span></a></li> <li><a href="http://www.ncbi.nlm.nih.gov/pubmed/3768116" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">Neurovascular anatomy and elbow arthroscopy: inherent risks<span class="wpel-icon wpel-image wpel-icon-6"></span></a>.</li> <li><a href="http://www.ncbi.nlm.nih.gov/pubmed/26152782" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">Elbow Positioning and Joint Insufflation Substantially Influence Median and Radial Nerve Locations<span class="wpel-icon wpel-image wpel-icon-6"></span></a></li> <li><a href="http://www.ncbi.nlm.nih.gov/pubmed/8421009" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">Avoiding nerve damage during elbow arthroscopy<span class="wpel-icon wpel-image wpel-icon-6"></span></a>.</li> <li><span id="scm6MainContent_lblArticleTitle"><a href="http://www.ncbi.nlm.nih.gov/pubmed/23925741" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">Prevention of Nerve Injury During Arthroscopic Capsulectomy of the Elbow Utilizing a Safety-Driven Strategy<span class="wpel-icon wpel-image wpel-icon-6"></span></a></span></li> <li><a href="http://www.ncbi.nlm.nih.gov/pubmed/7641472" data-wpel-link="external" target="_blank" rel="external noopener noreferrer" class="wpel-icon-right">Arthroscopic surgery of the elbow.
