8. PROGNOSTIC FACTORS
ā¢ i. Severity of initial paralysis
ā¢ ii. Diffuseness of its regional distribution
ā¢ Iii. Expectations & support
ā¢ Iv. Resources availibilty
ā¢ In general, the more extensive the paralysis in the
first 10 days of illness the more severe the ultimate
disability.
9. OPTIONS: RECONSTRUCTIVE SURGERY
1. Release of contractures : Fasciotomies &
Capsulotomies
II. Re-establishment of power by:
a) Tendon transfer to prevent deformities
b) Muscle transplantation: to replace a
paralyzed muscle
III. Stabilization of a relaxed or flail joint by:
(a) Tenodesis
(b) Construction of Bone block
Tenodesis of Achilles tendon to fibula
Posterior bone block
10. OPTIONS : RECONSTRUCTIVE SURGERY
IV. Correction of Deformities by
a) Osteotomies b) Arthrodesis
V. Limb lengthening (Ilizarov techniques to
release contracture & Limb Lengthening)
VI. Joint replacement surgery
VII. Correction of pelvic obliquity & Spine
deformity & stabilization

BIOMECHANICAL CLASSIFICATION
OF SHOULDER GIRDLE MUSCLES
Prime Movers 1. Deltoid
2. Pectoralis Major
ā¢ Bulky muscles
ā¢ Act on long lever
ā¢ Clavicular head exert major
force for abduction
Steering Group:
Superior Sterer
Supra Spinatus ā¢ By virtue of their
insertions near articular
surface & Neck-shaft axis
ā¢ Steer the head on
Gelenoid Surface.
ā¢ Exert Stablizing force
ā¢ Have limited lifting force
Horizontal Anterior steerer Sub Scapularis
Horizontal Posterior Steerer Infra Spinatus
Teres Minor
15. Depressor Group:
Intermediate Group 1. Pectoralis Major
Sternal Head
2. Latissimus Dorsi
3. Teres Major
ā¢ Rotates Humeral
head during
elevation &
the head towards
later part.
ā¢ Also Exert week

19. DELTOID PALSY
TENDON AND MUSCLE TRANSFERS
Classic methods:
ā¢Bateman Trapezius Transfer. Single muscle transfer,
without consideration to the functions of the steering muscles.
ā¢Arthrodesis of the Shoulder
When there is, paralytic subluxation or dislocation of
shoulder with extensive paralysis of the scapulohumeral
muscles.
20. DELTOID PALSY:
BATEMAN TRAPEZIUS TRANSFER
ā¢ Spine of scapula osteotomised
near its base in obliquity distal
& lateral.
ā¢ Split atrohic deltoid
ā¢ Roughen deep surface of
acromion, spine &
corresponding area of humerus.
ā¢ Resect lateral end of clavicle.
ā¢ Anchor acromion to humerus
as far distaly as possible with 2-
3 screw.

21. DELTOID PALSY:
SAHAāS TRANSFER OF TRAPEZIUS
ā¢ Entire insertion of
Trapizius along with
attached lateral end of
clavicle, A-C joint &
Acromion & adjacent part
of scapular spine to be
anchored to lateral aspect
of humerus distal to
tuberosity by two screws.
22. PARTIAL DELTOID PALSY:
HARMON TRANSFER OF DELTOID
A.Posterior part of deltoid is
functioning, middle & anterior part
Paralyzed.
B.Posterior functioning part of
deltoid transferred over atrophic
anterior deltoid.
āMechanism: Transferred posterior part of deltoid
overlying atrophic anterior part, when contracts, it
prevents anterior dislocation of shoulder and
exerts more direct abduction force than in its
23. ARTHRODESIS
PRE-REQUISITES
Followin a shoulder fusion the scapulothoracic
motion will serve as a substitute for
glenohumeral joint motion, hence following
Primary pre-requisites are very important to have:
ā¢ Normal motor strength of the trapezius and
serratus anterior
ā¢ Normal function of the hand
Best to delay Shoulder fusion until epiphyseal closure has taken
place. Source: Benjamin Josef
24. SHOULDER ARTHRODESIS
OPTIMUM POSITION
AAOS Recommendation
Most acceptable position:
ā¢ 500 of abduction,
ā¢ 200 of flexion,
ā¢ 250 of internal rotation.
This position is functional, that allows the
patient to reach the face and top of the
head with the elbow flexed.
Variation n females:
ā¢ 300 of abduction,
ā¢ 5-100 of flexion
ā¢ 450 of internal rotation
The lesser degree of abduction is
functionally compensated for by
fusing it in greater internal
rotation.
Caution: Shoulder should never be fused in external rotation
because the limb will be positioned in an awkward and functionally poor position.
25. OPTIMUM POSITION
VERY CRITICAL TO ACHIVE, FOR A GOOD FUNCTIONAL LIMB
Caution: Shoulder should never be fused in external rotation
because the limb will be positioned in an awkward and functionally poor position.

42. RECONSTRUCTION FOR PATTERN III, PARALYSIS
1st Stage
ā¢ For thenar muscle paralysis, the
trapeziometacarpal arthrodesis for
intermetacarpal bone graft procedure is done to
maintain thumb in fixed palmar abduction.
ā¢ For the weak finger intrinsics (claw), volar
capsulodesis is done at the same stage.
ā¢ Followed by a 3 wks of plaster immobilization.
43. RECONSTRUCTION FOR PATTERN III PARALYSIS
2nd Stage To improve flexion of the fingers and thumb
ā¢ The FDP tendon slips are side-stitched or tenodesed to each other at the
distal forearm so that whatever available flexion power there is can be
evenly distributed for all fingers.
3rd Stage Drop Wrist
ā¢ When the pronator or a strong superficialis tendon is available, the transfer
of either of these to the ECRB tendon provides wrist extension.
ā¢ The available FCU or FCR can also be transferred to the EDC and EPL for
finger and thumb extension
