FRACTURE & DISLOCATION

FRACTUREDefinition :A fracture, whether of a bone, an epiphyseal plate or a cartilaginous joint surface, is simply a structural break in its continuity.

must be consider : surrounding soft tissue around the fracture site

Page 3: 30.Trauma musculoskeletal blok 27.ppt

Physical factors in the Production of Fractures

1. Cortical Bone: can withstand compression and shearing forces better

that it can withstand tension forces

Page 4: 30.Trauma musculoskeletal blok 27.ppt

2. Cancellous Bone/ spongious:Can’t withstand compression.

Can produced: Crush # / compression # Impacted #

Page 5: 30.Trauma musculoskeletal blok 27.ppt

Descriptive Terms Pertaining to Fractures

1. Fracture site : Diaphyseal Metaphyseal Epiphyseal

Page 6: 30.Trauma musculoskeletal blok 27.ppt

2. Extent of Fracture:complete Incomplete

Page 7: 30.Trauma musculoskeletal blok 27.ppt

3. Configuration of #:1. Transverse2. Oblique3. Spiral4. Comminuted

1 2 3 4

Page 8: 30.Trauma musculoskeletal blok 27.ppt

4. Relationship of the Fracture Fragments to Each Other :UndisplacedDisplaced :

1. Overriding2. Angulated3. Rotated4. Distracted5. Impacted6. Shifted

sideways

Relationship of the fracture fragments to each other caused by :

• Effects of Gravity• Effects of muscle pull on the fragments

Page 9: 30.Trauma musculoskeletal blok 27.ppt

5. Relationship of the Fracture to the External Environment: Closed # Open #:

Fracture fragment has penetrated the skin ( from within)Sharp object has penetrated the skin to # the bone (from

without)

6. Complication : Uncomplicated Complicated:

Local : InfectionSystemic : Emboli, Sepsis

Page 10: 30.Trauma musculoskeletal blok 27.ppt

THE DIAGNOSIS OF FRACTURES

HISTORY :Fall, Direct Trauma.Mechanism of injury.Common symptom of # :

Localized pain.Decreased function of the involved part.

Page 11: 30.Trauma musculoskeletal blok 27.ppt

THE DIAGNOSIS OF FRACTURES

PHYSICAL EXAMINATION:INSPECTION ( LOOKING ):

Swelling ( edema )Deformity( angulations, rotation, shortening )Abnormal movementEchymosis( subcutaneous extravasations of blood )

PALPATION ( FEELING ) :Localized tenderness at the # site.Crepitus (not necessary)

RANGE OF MOVEMENT (ROM):Limitation.

Page 12: 30.Trauma musculoskeletal blok 27.ppt

THE DIAGNOSIS OF FRACTURES

!!!! CAREFULL ASSESSMENTPatient’s General ConditionSearch for associated injuries:

BrainSpinal CordPeripheral NervesMajor vesselsThoracesAbdominal viscera

Page 13: 30.Trauma musculoskeletal blok 27.ppt

THE DIAGNOSIS OF FRACTURES

RADIOGRAPHIC EXAMINATION:# : PHYSICAL EXAMINATIONConfirmation by X-Ray Accurate DiagnosisTo determine extent and configuration of the fracture.Include entire length of the bone and the joints at

each end.2 Projection : AP / Lat, particularly obliqueSpine and pelvis : (+) CT

Page 14: 30.Trauma musculoskeletal blok 27.ppt

THE NORMAL HEALING OF FRACTURES1. Cortical bone (diaphyseal bone/ tubular

bone)# torn of blood vessels, canaliculi, Haversian canal

A vascular Bleeding from periosteum

1. Fracture Hematoma ↓ Localized on the end of fragment # Osteogenic cells from periosteum formed External callus

Endochondral Ossification2 Clinical Union ( fracture line still

apparent)3 Consolidation ( Radiographic Union )4 Remodeling

THE TIME REQUIRED FOR UNCOMPLICATED # HEALING

FACTOR INFLUENCE:1. Age of the patient Younger age, the healing rate faster.

Example : femur # after birth union 3 weeks

femur # on the age 8 year union 8 weeks femur # on the age 12 year union 12 weeks femur # on the age 20 th/> union 20 weeks

Page 19: 30.Trauma musculoskeletal blok 27.ppt

HEALING TIME UNCOMPLICATED #

2. # Site and Configuration # through bones that are surrounded by

muscle >union faster cancellous bone # > union faster than

cortical bone long oblique / spiral # > union faster than

transverse #

Page 20: 30.Trauma musculoskeletal blok 27.ppt

WAKTU PENYEMBUHAN # UNCOMPLICATED

3. Initial Displacement of the Fracture :undisplaced #, intact periosteum heal twice as rapidly as displaced #

4. Blood supply to the Fragments :If both fracture fragments have a good blood supply healing faster

Page 21: 30.Trauma musculoskeletal blok 27.ppt

ABNORMAL HEALING OF FRACTURES

MALUNION Heal normally expected time but in unsatisfactory

position with residual bone deformity DELAYED UNION

union time longer than normal NON UNION

fractures fail to heal by bone : Fibrous Union False joint (Pseudoarthrosis)

Page 22: 30.Trauma musculoskeletal blok 27.ppt

PRELIMINARY CARE FOR PATIENTS WITH #

PRIORITY1. Airway2. Breathing3. Shock4. # and dislocation

CLASSIFICATION OF OPEN #

TYPE IWound Ø < 1 cmClean woundBone penetrated skin with minimal injury

to the muscle (usually from within)Simple #, transverse, short oblique

Page 25: 30.Trauma musculoskeletal blok 27.ppt

CLASSIFICATION OF OPEN #

TYPE III:Extensive soft tissue damage ; skin,

muscle, nerve injuries and major arterial injury

Often caused by high speed injuryExample :Traffic accident, farm accidentsGunshot wound> 8 hours

DISLOCATIONStructural loss of its stability3 structure that prevent normal ROM & also

prevent joint stability

Joint shape ( joint surface )

Capsule and ligament

Muscle that prevent joint stability

Page 29: 30.Trauma musculoskeletal blok 27.ppt

DISLOCATION

3 DEGREES OF JOINT INSTABILITY :1st Degree : Occult Joint instability

( apparent only when joint is stressed)2nd Degree : Subluxation ( less than luxation) 3rd Degree : Dislocation (Luxation)

( joint surfaces have completely lost contact)

Page 30: 30.Trauma musculoskeletal blok 27.ppt

DISLOCATION

Joint most susceptible to traumatic dislocation:

ShoulderElbowHipInter phalangealAnkle

Page 31: 30.Trauma musculoskeletal blok 27.ppt

DIAGNOSIS

Physical Examination :Swelling (edema)Deformity ( angulation, rotation, loss of normal

contour, shortening)Abnormal movementLocal tenderness

Radiographic Examination :Typical features of a subluxationAP / LAT projection

Page 32: 30.Trauma musculoskeletal blok 27.ppt

SPECIFIC TYPES OF JOINT INJURIES CONTUSION:

Hemarthrosis (rupture of synovial vessels) Normal X-rayLIGAMENTOUS SPRAIN: Acute sprain, strain sudden stretching of the

ligament withincomplete tears local hemorrhage local swelling tenderness, pain aggravated by movement

Radiographic examination : normal Treatment : strapping / splinting

DISLOCATION : Anatomical reduction immobilization

dislocation of the distal radio-ulnar joint. displaced # of distal third of the radial

shaft associated with complete disruption & dislokation of the distal radioulnar joint.

SHOULDER JOINT

1. Shoulder Joint Dislocation Anterior Dislocation of the Shoulder

Predominantly of young adults Caused by forced external rotation and extension of the

shoulder Radiographic examination : confirm the diagnosis Treatment :

Reduce as soon as possible, methods : Kocher Method Gravitation HipocratesAfter reduce must immobilized by Velpeau Bandage

Page 60: 30.Trauma musculoskeletal blok 27.ppt

SHOULDER JOINT

2. Recurrent Anterior Dislocation of The Shoulder :The stability of the shoulder depend on the integrity of

the joint capsule capsule, capsule & anterior labrum are nearly always avulsed caused the dislocation may recur more and more frequently with less and less violence.

Treatment :Surgical repair with Putti Platt operation capsule as well as

the Subscapularis muscle are divided and then refeed (overlapped) limiting external rotation.

Page 61: 30.Trauma musculoskeletal blok 27.ppt

SHOULDER JOINT3. Posterior Dislocation of the ShoulderLess common than anterior dislocationPosterior dislocation can occur :

Fall on the front of the shoulder, with shoulder adducted and internally rotated

Clinical Finding :The patient’s arm seems locked in a position of adduction and

internal rotattedRadiographic finding:

Not readily detected in an AP projection, need special examination :Superoinferior (axillary) projection with the shoulder abducted, is

necessary to confirm that the humeral head is in fact lying posteriorly
