ARTHRODESIS 1
ARTHRODESIS 2
ARTHRODESIS 3
INDICATIONS
Indications for shoulder fusion have diminished over the years because of:
the excellent results of shoulder arthroplasty.
the near elimination of poliomyelitis and tuberculosis.
the improved techniques for shoulder
stabilization.
ARTHRODESIS 4
ARTHRODESIS 5
Contraindications
Osteonecrosis.
Charcot arthropathy(nonunion rate is high).
Ipsilateral elbow fusion.
Contralateral shoulder fusion.
ARTHRODESIS 6
We agree that the position of rotation is the most critical factor in obtaining optimal function.
ARTHRODESIS 7
ARTHRODESIS 8
SURGICAL TECHNIQUES
the limited contact between the glenoid fossa and humeral head can be improved by including the acromion in the fusion mass.
Firm internal fixation usually eliminates the need for bone grafting and external fixation.

45 Degrees
spica cast 12 to 16 weeks
ARTHRODESIS 13
AFTERTREATMENT:• A pelvic band extending from the nipples to
the pubic symphysis is applied.• With the elbow flexed 90 degrees, a cylinder
cast is applied to the upper extremity. • The extremity is suspended by two wooden
struts, or a cock-up wrist splint is used.• At 1 to 2 weeks after surgery, a plastic
shoulder spica cast is applied and worn until union is achieved, 12 to 16 weeks after surgery.

ARTHRODESIS 19
ARTHRODESIS 20
ARTHRODESIS 21
POSITION
For unilateral arthrodesis of the elbow, a position of 90 degrees of flexion is desirable.Bilateral elbow arthrodesis rarely is indicated because of resultant functional limitations. If indicated, one elbow should be placed in 110 degrees of flexion to permit the patient to reach the mouth and the other should be
placed in 65 degrees to aid in personal hygiene.
ARTHRODESIS 22

elbow .
TECHNIQUE 4(Arafiles)

olecranon fragments as bone grafts

TECHNIQUE 5 (Müller et al.)

arthrodesis is solid
ARTHRODESIS 27
TECHNIQUE 6 (Spier)
The most common indication was a high-energy, open, infected injury with associated bone loss.
Apply bone graft
The plate and screws 1year only
ARTHRODESIS 28
ComplicationsComplications of elbow arthrodesis include:• Delayed union.• Nonunion.• Malunion.• Neurovascular injury .• Painful prominent hardware .• Skin breakdown.
ARTHRODESIS 29
ARTHRODESIS 30
ARTHRODESIS 31
Contraindicationsinclude :• An open physis of the distal radius( The distal
radial physis close approximately 17 years of age).
• After partial destruction of the physis ,the remaining part may be excised to prevent unequal growth.
• An elderly patient with a sedentary lifestyle, especially if the nondominant wrist is involved.
ARTHRODESIS 32
POSITION Usually 10 to 20 degrees of extension (dorsiflexion) with the long axis of the third metacarpal shaft aligned with the long axis of the radial shaft (allow maximum grasping strength).In general, neutral to 5 degrees of ulnar deviation is preferred. If bilateral wrist fusions are indicated, the positions of the wrists should be determined by the needs of the patient( The neutral position).
ARTHRODESIS 33
The straight plate is employed when a large intercalary graft is required for a traumatic or tumorous defect.
The short carpal bend is used in small wrists and those in which the proximal row has been resected.
The longer carpal bend is used in large wrists.
ARTHRODESIS 34

Cast 6-8weeks
ARTHRODESIS 38
ARTHRODESIS 39
ARTHRODESIS 40
INDICATIONS Damaged by injury or disease. Pain. Deformity. Instability makes motion a liability rather than an asset.Arthrodesis is used most often for the proximal interphalangeal joint because motion in this joint is so important. When the metacarpophalangeal joint is destroyed, if good muscle strength is present,
arthroplasty is indicated more often than arthrodesis.
ARTHRODESIS 41
POSITION
The metacarpophalangeal joint should be fixed in 20 to 30 degrees of flexion.The proximal interphalangeal joints should be fixed from 25 degrees of flexion in the index finger to almost 40 degrees in the small finger (less flexion in the radial fingers than in the ulnar fingers). The distal interphalangeal joints are fixed in 15 to 20 degrees of flexion.
