CASE #1
• 7 year old child fell jumping from couch
• Pain and swelling around elbow
• X-rays• Where’s the
trouble?

Supracondylar Fractures
• Peak age 5-8 years• Males > Females (2:1)• Left>Right(61%/39%)• Open Fractures (1%)• Rare “floating elbow”• Nerve injury 7% all fractures, up to 49% of
type III fractures (Waters, et al)
![Page 8: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/8.jpg)
Supracondylar Fractures
• Highest rate of complications of any pediatric fracture– Malunion– Neurovascular
Impairment– Compartment Syndrome
![Page 9: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/9.jpg)
Tip #1: Get the x-rays right
Lateral xrays: ANTERIOR humeral line, “teardrop”
AP x-rayBaumann’s angle
• 9-26 deg• Need true AP distal
humerus 90deg beamSkaggs
![Page 10: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/10.jpg)
Tip #2: Know fracture type• Direction of displacement:
-extension type (98%)*posterior - medial*posterior - lateral
-flexion type• Amount of displacement / stability
-Gartland Types I/II/III/IV***Floating Elbow
![Page 11: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/11.jpg)
Type I• Non-displaced• Positive fat pad
sign on lateral (posterior)
• Symmetric Baumann’s angle and humeral condylar line
• Stable
![Page 12: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/12.jpg)
Type II• Displaced with
posterior cortex intact
• Requires reduction– Flexion/Hyperpronation– Not always
• Malunion risk– Lateral condyle fractures– Loss of function– Cubitus Varus
![Page 13: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/13.jpg)
Type III / IVTYPE III / IV• III– Displaced with no cortical
contact
• IV– Extension to flexion type
• High risk of complications
![Page 14: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/14.jpg)
Flexion Type
• Different reduction maneuver
• Trouble is lack of extension and varus

Non-Op Closed Reduction• < 120 deg flexion casting
– Loss of reduction >50%• (Millis CORR 1984)
– Volkman’s ischemia(Kurer CORR 1990)
• Cast < 90 degs(Pirone JBJS 1988)
TROUBLE:
– rotational deformity– coronal malalignment– significant extension

Percutaneous Pinning• History:– Miller (1939),
Swenson (1948)
• Best results, rare complications– (Flynn 1986)
• Minimal to no risk of physeal arrest
• Low rate of malunion• Iatrogenic ulnar
nerve injury with medial pin <3% (Royce1991)
• pin tract infection (0-7%)
![Page 17: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/17.jpg)
Pin Placement– 3 lateral entry pins
• greatest combination of torsional and bending stiffness• With medial comminution, adding a medial pin increased
torsional stiffness and bending stiffness (Silva, 2013)
– Spread and divergence– Ulnar nerve iatrogenic injury - healthy debate

Lateral condyle fractures
12 - 17% of all elbow fractures in childrenSecond most common elbow fractureUsually ages 4 – 10 yearsMechanism of injury: varus stress imparted
on extended elbow and supinated forearm
History of fall, traumaPain, swelling, limited elbow motion

operative?– Prone
• Considerations– Hand dominance– Demands– Ulnar nerve function

Pediatric Monteggia Fractures• Radial head ossifies ~ age 4
• Classification– Type I: most common, anterior dislocation – Type II: posterior dislocation of the radial head – Type III: lateral dislocation of radial head w/ ulnar metaphyseal
fracture, usually a greenstick • assoc w/ radial nerve injuries & is 2nd most common type
– Type IV: anterior radial head dislocation and fractures of both the proximal radius and ulna
• Monteggia equivalent = fracture of proximal radius or physeal injury
![Page 41: Trouble in Pediatric Elbow Fractures](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f5c31d9873742ad84441cd/html5/thumbnails/41.jpg)
Pediatric Monteggia Fractures• Treatment
– MOST closed, close follow up• Type I, III, and IV Monteggia injuries
– immobilize elbow in 100 deg of flexion w/ forearm fully supinated for 6 weeks
• Type II injuries, immobilize w/ elbow extended for four weeks
• If unable to achieve reduction; – improper position of elbow ( < 110 deg of flexion) – infolded annular ligament; PIN– radial head buttonholed thru capsule/brachialis
• Open reduction– is indicated if it is necessary to reduce radial head– if reduction of radial head is not maintained– IM fixation of ulna fracture usually enough– PIN loss after closed reduction

Missed Monteggia
• Often devestating• Require ulnar
osteotomy and/or annular ligament reconstruction
• Long term range of motion issues
• 200% surgical complication rate reported
