Arthroscopy portals

Yongwei Pan, Leung-Kim Hung
Purpose The terminal branches of the posterior interosseous nerve (PIN) are the main articular branch on the dorsal aspect of the wrist. Its relationship to dorsal wrist arthroscopic portals has not yet been elucidated. The purpose of this study was to quantitatively describe the anatomical relationships between the dorsal wrist arthroscopic portals and the PIN. Methods Dorsal wrist arthroscopic portals were established in 28 cadaver extremities, after which the limbs were dissected. Measurements were taken from the portals to the PIN...

Three direct volar portals for wrist arthroscopy have been described previously: two radiocarpal and one midcarpal. The aim of this study was to systematically describe four volar arthroscopic portals through minimally invasive incisions using an inside-out approach from known dorsal portals. Four volar arthroscopic wrist portals were studied on six hand specimens using an inside-out technique: a radial radiocarpal approach (RRCA), an ulnar radiocarpal approach (URCA), a radial midcarpal approach (RMCA) and an ulnar midcarpal approach (UMCA)...

Over the past 2 decades, hip arthroscopy has developed as a surgical technique, with more orthopaedic surgeons attempting to become proficient in performing this surgical procedure as indications and surgical skills evolve. The hip joint presents unique arthroscopic challenges because of its anatomic location, and it can be challenging to safely and confidently establish portal sites. Ultrasound-guided hip arthroscopy portal placement is not yet common practice for orthopaedic surgeons. The potential advantages of ultrasound-guided hip arthroscopy portal placement are the lack of radiation exposure to the patient and operating room personnel, direct visualization of the hip joint and surrounding soft-tissue structures, and lack of bulky fluoroscopic equipment in the operative field...

The use of an accessory posteromedial portal for posterior cruciate ligament reconstruction in bicruciate knee ligament reconstruction has often been described. However, the use of a posteromedial portal can be time consuming and has some inherent risks including injury to the saphenous vein or nerve. We describe our bicruciate knee ligament reconstruction using 4 exclusively anterior portals including a high anteromedial, high anterolateral, low anteromedial, and low anterolateral portals. Arthroscopy is performed using a combination of 30° and 70° arthroscopes...

Revision arthrodesis is indicated in symptomatic nonunion of the first tarsometatarsal joint. Revision by first tarsometatarsal arthroscopy cannot deal with the dilated screw tract and associated bone cysts. Revision by bone endoscopy is indicated in symptomatic nonunion of the first tarsometatarsal joint, which is previously fixed by transarticular screw along with loosening of the screw and bone cyst formation. The screw tract makes up the portal tract, with the proximal and distal ends of the tract corresponding to the proximal and distal portals, respectively...

BACKGROUND: Evolving wrist arthroscopy requires creating new portals, and creating portals reciprocally leads to increased indications for arthroscopic wrist procedures. To facilitate access to the lunate bone and fossa for new arthroscopic procedures, a new portal was used. This is a cadaveric study of this portal. OBJECTIVES: In this cadaveric study, we evaluated a portal in wrist arthroscopy for procedures involving the lunate bone and lunate fossa. MATERIALS AND METHODS: Seventeen wrists from 10 fresh cadavers were included in this study...

Introduction Pseudoaneurysm formation following ankle arthroscopy is a rare but potentially catastrophic complication. The placement of anterior ankle portals carries inherent risk to the superficial and deep peroneal nerves, as well as to the dorsalis pedis artery. Anatomical variations in the dorsalis pedis and the presence of branches at the joint line may increase the risk of vascular injury and pseudoaneurysm formation during arthroscopy. There is limited anatomical evidence available regarding the branches of the dorsalis pedis artery, which occur at the point at which they cross the ankle joint...

BACKGROUND: Prompt open arthrotomy is historically utilized to treat pediatric septic arthritis of the hip, but arthroscopy has been described as a valid alternative to prevent long-term sequelae. Standard hip arthroscopy in adolescents and adults utilizes lateral-based portals, but successful irrigation in infants may necessitate a medial portal due to the smaller joint size. The purpose of this study was to determine the safety of a medial hip portal in children based on its anatomic relation to neurovascular structures...

Hip arthroscopy in patients with osteoarthritis has been shown to have suboptimal outcomes. Elevated cytokine concentrations in hip synovial fluid have previously been shown to be associated with cartilage pathology. The purpose of this study was to determine whether a relationship exists between hip synovial fluid cytokine concentration and clinical outcomes at a minimum of 2 years following hip arthroscopy. Seventeen patients without radiographic evidence of osteoarthritis had synovial fluid aspirated at time of portal establishment during hip arthroscopy...

Hip arthroscopy has gained popularity in recent years for diagnostic and therapeutic hip preservation management. This article details the establishment of arthroscopic portals of the hip, specifically the anterolateral and modified anterior portals without fluoroscopic guidance. The anterolateral portal is established anatomically, and the modified anterior portal is then established under arthroscopic guidance. A through understanding of the hip anatomy allows for these portals to be made both safely and reliably for hip arthroscopies in the modified supine positioned patient...

Access to all areas of the ankle during arthroscopy is always problematic. The use of the correct portals and distraction increases access in both the supine and prone positions. Noninvasive distraction up to 30 pounds is safe and effective to perform arthroscopy in the supine position, and avoids the potential complications of pin distraction.

PURPOSE: In this anatomical cadaver study, the distance between major nerves and ligaments at risk for injury and portal sites created by trainees was measured. Trainees, inexperienced in elbow arthroscopy, have received a didactic lecture and cadaver instruction prior to portal placement. The incidence of iatrogenic injury from novice portal placement was also determined. METHODS: Anterolateral, direct lateral, and anteromedial arthroscopic portals were created in ten cadavers by ten inexperienced trainees in elbow arthroscopy...

Subtle injuries of the Lisfranc joint complex are uncommon and difficult to diagnose clinically and thus are easily missed even by experienced orthopedic doctors. Misdiagnosed injuries can lead to chronic disability until eventual fusion surgery. We describe 10 cases diagnosed with subtle injury of the Lisfranc joint that were treated with combined innovative portal arthroscopy and fluoroscopy-assisted reduction and percutaneous screw fixation in an interfragmentary fashion. The distance between the first and second metatarsals (the Lisfranc distance) and that between the medial cuneiform and fifth metatarsal base (foot arch height) was measured before and after surgery...
