2. Introduction
• 1931 Burman
• Initial Description in 1980s
• Confined space, complex
articulation, proximity of major
neurovascular structures
• Initially used primarily as a
diagnostic tool, now routinely
used to treat
3. • Advantages
• Improved articular visualization
• Decreased postoperative pain
• Faster postoperative recovery
• Disadvantages
• Technically demanding
• High risk of damage to
neurovascular structures due to
proximity to the joint
10. Prone Elbow Arthroscopy
Advantages
• Best access to posterior portal
• No arm support necessary
Disadvantages
• More difficult anesthesia
• Difficult to convert to open
• Image reversal
Lateral decubitus elbow arthroscopy
• Same advantages with the prone position
• It does not compromise the airway
Supine Elbow Arthroscopy
Advantages
• Best anterior access
• Easier anesthesia
• Easy conversion to open
Disadvantages
• Difficult posterior access
and orientation
11. Portal Placement
Technique
• Portal placement technique
• fully distend joint through lateral soft spot
placing portal
• capsule distension moves NV structures away from
the joint when trocar is introduced
• careful "nick and spread" technique using hemostat
• Needle technique for the rest

Portals Situation Use Neurovascular
Straucuture
MALP directly anterior to
the radiocapitellar
joint
workhorse of the lateral
portals.
9.8 mm from the radial
nerve
PALP 1-2cm proximal, 1cm
anterior to lateral
epicondyle
See radial head, medial
side of elbow, coronoid,
trochlea, brachialis
insertion, coronoid fossa
Radial nerve with an
average distance
ranging from 9.9 to 13.7
mm and 6 mm from the
LABCN
DALP 3 cm distal and 1 cm
anterior to the LE

radial nerve 4.0 to
7.2 mm.LABCN is
approximately 7.6 to
12.6 mm away
16. Portal Location Use Neurovascular
Structures
Anteromedial
Portal
2 cm anterior and
2 cm distal to the
ME.
Used most often to
augment the proximal
anteromedial portal to
access medial recess.
Place under direct
visualization.
Median nerve 5.0 to 7.0 mm MABCN
1.0 to 8.9 mm away, Brachial artery
15.2 to 16.6 mm
Mid-
anteromedial
Portal
1 cm proximal and
1 cm anterior to
the ME.
Given its close proximity
to the anteromedial
portal and proximal
anteromedial portal
(PAMP), it is rarely used
13.8 mm from the median nerve,
17.6 mm from the brachial artery,
and 7.0 mm from the MABCN
Proximal
Anteromedial
Portal
2 cm proximal to
the ME and
immediately
anterior to the
intermuscular
septum

compartment, radial
head, capitellum,
coronoid, trochlea
Most commonly used

NIL

20. PALP provides good visualization of the anterior
ulnohumeral and radiocapitellar joint
Soft Spot Portal Best Visualization
• Posterior Surface of Radial Head • Posterior Capitellum •
Radial Surface of Olecranon
25. Most experienced only
• Capsulectomy •Osteocapsular
arthroplasty • Fracture fixation
Low
Diagnostic arthroscopy, Loose body
removal , Plicae excision Debridement of OCD
Advanced
• Synovectomy • Capsulotomy •
Radial head excision • Lateral
epicondylitis release
Level of experience
26. Pearls
• PROPER POSITIONING OF THE
PATIENT
• Identification and labelling of all
landmarks
• Consideration of the intra-
articular pathology
• Fewest number of portals
required
• Beware of the location of Radial ,
Ulnar and Median Nerve
27. Pitfalls
• Beware of the prior surgical interventions
• Excessive swelling and fluid extravasation
• Each additional portal increase the risk of complications
• Inadvertent distal placement of anterior portals
decrease the safe working distance from critical
neurovascular distances
• Because of the location of the Ulnar nerve , here is no
true safe zone on the medial side
28. • Elbow arthroscopy is a difficult procedure with a
steep learning curve
• As experience is gained indications are expanding
• Start with easier procedures and stay in the safe
side
