ANATOMY OF THE ELBOW
HUMERUS
• Capitulum (lateral) radial head• Trochlea (medial) trochlear notch of the ulna• Anterior Coronoid fossa receives coronoid
process of ulna during full flexion• Posterior Olecranon fossa receives olecranon of
ulna during extension• Radial fossa receives edge of head of radius
during full flexion
ULNA
• Stabilizing bone• Located medially, longer• Articulation between ulna and humerus flexion,
extension (with minimal abduction and adduction during pronation - supination)• Tapers at the end to form the ulnar head and the
styloid process• Doesn’t reach and participate in joint action
RADIUS
• Head of the radius and capitulum flexion and extension of the elbow

SUPRACONDYLAR HUMERUS FRACTURES
• Fractures of the distal humerus just above the epicondyles• Typically remains extra articular• 55% to 75% of all elbow fractures• Peak incidence 5 to 8 years, after which
dislocations become more frequent• The left, or nondominant side, is most frequently
injured
SUPRACONDYLAR FRACTURES
• In 5 – 8 year olds, bone remodeling causes a decreased anteroposterior diameter in the supracondylar region, making this area susceptible to injury
• Ligamentous laxity in this age range increased likelihood of hyperextension injury
• The anterior capsule is thickened and stronger than the posterior capsule. • In extension: the fibers of the anterior capsule are taut, serving as a
fulcrum by which the olecranon becomes firmly engaged in the olecranon fossa
• With extreme force: hyperextension may cause the olecranon process to impinge on the superior olecranon fossa and supracondylar region
• The periosteal hinge remains intact on the side of the displacement
MECHANISM OF INJURY
• Extension type • Hyperextension occurs during fall onto an outstretched
hand with or without varus/valgus force• Hand is pronated posteromedial displacement
*More common*Possible radial nerve injury
• Hand is supinated posterolateral displacement *Possible median nerve and vascular compromise
• Flexion type: Caused by direct trauma or a fall onto a flexed elbow
• Typical presentation: swollen, tender elbow with painful range of motion
• S-shaped angulation at the elbow: a complete (Type III) fracture results in two points of angulation to give it an S shape.
• Pucker sign• Dimpling of the skin anteriorly secondary to penetration of the
proximal fragment into the brachialis muscle• Means reduction of the fracture may be difficult with simple
manipulation
• Evaluate integrity of the median, radial, and ulnar nerves plus their terminal branches
• Can be occult on radiographs with only a positive fat pad sign

SUPRACONDYLAR FRACTURES
Type I: NondisplacedType II: Displaced with intact posterior
cortex; may be angulated or rotated
Type III: Complete displacement; posteromedial or posterolateral
Gartland Classification based on the degree of displacement
EXTENSION TYPE (98%)
FLEXION TYPE (2%)
Type I: NondisplacedType II: Displaced with intact anterior
cortexType III: Complete displacement; usually
anterolateral
GARTLAND - EXTENSION TYPE
type I (undisplaced), II (displaced with an intact posterior cortex), and III (displaced with no cortical contact)
TREATMENT – EXTENSION TYPE
Type I: Immobilization in a long arm cast or splint at 60 to 90 degrees of flexion is indicated for 2 to 3 weeks.
Type II: This is usually reducible by closed methods followed by casting; it may require pinning if unstable (crossed pins versus two lateral pins) or if reduction cannot be maintained without excessive flexion that may place neurovascular structures at risk.
Type III: Attempt closed reduction and pinning; traction (olecranon skeletal traction) may be needed for comminuted fractures with marked soft tissue swelling or damage.Open reduction and internal fixation may be necessary for rotationally unstable fractures, open fractures, and those with neurovascular injury (crossed pins versus two lateral pins).
TREATMENT – FLEXION TYPE
Type I: Immobilization in a long arm cast in near extension is indicated for 2 to 3 weeks.
Type II: Closed reduction is followed by percutaneous pinning with two lateral pins or crossed pins.
Type III: Reduction is often difficult; most require open reduction and internal fixation with crossed pins.
BONE HEALING
• Primary• Cortex attempts to heal without callus formation• Occurs when fx is anatomically reduced, the blood supply
is preserved, and the fracture is rigidly stabilized
• Secondary• Formation of callus • Involves participation of the periosteum and external soft
tissues
4 STAGES OF FRACTURE HEALING
1. Hematoma formation (inflammation) and angiogenesis.
2. Cartilage formation with subsequent calcification3. Cartilage removal and bone formation4. Bone remodeling
STAGE 1 - HEMATOMA FORMATION AND ANGIOGENESIS
• < 1 week after a fracture• Transforming growth factor beta (TGF-) and
platelet derived-growth factor (PDGF) are released from platelets at the fracture site• Osteogenic cells and inflammatory cells
ensheathe the fracture and differentiate into chondrocytes or osteoblasts.
STAGE 2 - CARTILAGE FORMATION WITH SUBSEQUENT CALCIFICATION
• ~ 1 to 3 weeks after fracture• Radiologic evidence of mineral formation signals
the onset of this phase. • consisting of calcified cartilage, woven bone
made from cartilage, and woven bone formed directly.• Woven bone replaces cartilage in callus by active
transport of minerals and their precipitation from a supersaturated solution
STAGE 3 - CARTILAGE REMOVAL AND BONE FORMATION
• ~ 1 to 3 months after fracture• woven-bone mineralized callus replaced by
lamellar bone arranged in osteonal systems • 3 characteristics:– It forms only under conditions of mechanical stability;– It has the ability to replace fibrous or muscle tissue; and– It forms within the confines of the bone defect
STAGE 4 – BONE REMODELLING
• Can be around several years• meticulously coordinated removal of bone from
one site and deposition in another.• Two lines of cells, osteoclasts and osteoblasts, are
responsible for this process• Osteoclasts – resorption• Osteoblast - accretion
MALUNION
• Described to be a fractured bone that did not heal in an anatomic position• Bone may have: • Angulated• Rotated out of position• Overrided another bone
• Causes shortening of the limb
• Shortening is better tolerated in the upper limb• >1 inch poorly tolerated in the lower limb• Causes:• Inadequate immobilization• Misalignment• Premature removal of an immobilizer
• Surgical Indication: • Pain• Impaired normal function
NON-UNION
• Healing by fibroblastic response instead of bone formation• Caused by:• Overdistraction• Excessive motion • Inadequate immobilization
MALUNION VS. NON-UNION
MANAGEMENT
• Traditional management- relied the intact posterior periosteum to maintain the stability of a closed reduction. • no longer recommended because the forced
flexion required to maintain stability of the fracture leads to excessive pressure in the antecubital fossa and increases the risk of compartment syndrome.
• anatomical closed reduction of the fracture then hold it in position with two or three pins introduced from the lateral side of the distal fragment. • splinted in 45 degrees of flexion, a safe position
for the swelling and circulation. • pins can be removed in three to four weeks, with
resumption of full activities a month later.
• Laterally introduced pins are preferred to crossed pins because there is a 2% to 6% risk of iatrogenic ulnar nerve injury.
• Crossed pinning of a supracondylar fracture. Both columns are pinned and the fracture is stable
OSTEOTOMY
• surgical operation whereby a bone is cut to shorten, lengthen, or change its alignment. Can be used to straighten a bone that has healed crookedly following a fracture.
• Immobilization in a long arm cast (or posterior splint for swelling) with the elbow flexed to 90 degrees and the forearm in neutral for 2 to 3 weeks postoperatively, at which time the cast may be discontinued and the pins removed• The patient should then be maintained in a sling
with range-of-motion exercises and restricted activity for an additional 4 to 6 weeks
COMPLICATIONS OF SUPRACONDYLAR FRACTURES
• Vascular Injury• Forearm compartment syndrome resulting in
Volkmann’s ischemic conracture• Nerve Injury• Cubitus varus deformity
COMPLICATIONS: VASCULAR INJURY
• Absence of radial pulse (10-20 %)• Most common with Type II and II SFs• Brachial artery – most freq. injured in
posterolaterally displaced fractures
COMPLICATIONS: VOLKMANN ISCHEMIC CONTRACTURE
• Vascular injury and swelling lead to the dev’t of compartment syndrome (w/in 12-24 hours)• Ischemia and Infarction can progress to
Volkmann’s Ischemic Fracture• Fixed flexion of the elbow• Pronation of the forearm• Flexion of at the wrist• Joint extension of the MTC-Phalangeal Joint
COMPLICATIONS: NEUROLOGIC DEFICIT
• Freq. 10-20 %, and increases with Type III SFs to 49%• Median Nerve Injury – Posterolateral distal fracture
fragment displacement w/ medial mov’t of the proximal fx fragment
• Radial Nerve Injury – Lateral proximal fracture fragment displacement
• Ulnar nerve Injury – Flexion type supracondylar fractures
COMPLICATIONS: CUBITUS VARUS DEFORMITY
• Angular deformity or ‘gunstock’ deformtiy – long term complication• Remodeling and correction of fracture angulation
is limited for children with SFs
PROGNOSIS OF PATIENTS WITH SFS
• Long term outcome and function• very good if the fracture is appropriately diagnosed and
treated
• Many of the associated complications• Self-limited• Amenable to functional repair w/ surgical intervention
