arthrodesis

 [ahr″thro-de´sis]
artificial ankylosis; surgical fusion of a joint.

arthrodesis

/ar·thro·de·sis/ (-de´sis) the surgical fixation of a joint by a procedure designed to accomplish fusion of the joint surfaces by promoting the proliferation of bone cells; called also artificial ankylosis.

arthrodesis

(är-thrŏd′ĭ-sĭs, är′thrə-dē′sĭs)
n. pl. arthrode·ses (-sēz)
The surgical fixation of a joint to promote bone fusion, used to treat intractable pain.

arthrodesis

surgical fusion of a joint. See ankylosis.

arthrodesis

The creation of a bony union across a joint, which can be either spontaneous or surgical.

Sites of surgical arthrodesis, best joints
Ankle, knee, shoulder, hip.
 
Indications
Differ according to the joint: ankle arthrodesis is performed for osteoarthritis, rheumatoid arthritis and post-traumatic arthritis; arthrodesis of the knee is usually performed as a last resort for infections (such as TB or neuropathic joint secondary to diabetes or syphilis), given the compromise in mobility that it causes.

Technique
Joints are denuded of cartilage, then shaped to conform to each other at the optimal angle; bone grafting is often used, as is some form of fixation, either internal (screws, rods, plates) or external (e.g., with a cast or external fixator).

arthrodesis

The fusion of the bones on either side of a joint so that no joint movement is possible. This may occur spontaneously, as a result of disease processes, or may be a deliberate surgical act done to relieve pain and improve function.

arthrodesis

surgical or pathological joint fusion, e.g. first metatarsophalangeal joint fusion in hallux rigidus (see Table 1) or subsequent to gout
Table 1: Classification of stage of hallux limitus/rigidus
StageCharacteristics
Stage 1
Functional HL
∼60° available dorsiflexion at 1 MTPJ
Functional (weight-bearing) limitation of dorsiflexion at 1 MTPJ, with:
• 1 MTPJ painful under load
• Hypermobility of first ray
• No real joint deterioration, but some osteophytosis
• Non-weight-bearing 1 MTPJ dorsiflexion near normal
Stage 2
Mild structural HL
35-55° available dorsiflexion at 1 MTPJ
Structural limitation of dorsiflexion at 1 MTPJ
• 1 MTPJ painful after exercise/movement
• Broadening and flattening of 1 MTPJ surfaces
• Narrowing of 1 MTPJ space
• Moderate osteophytosis of 1 MTPJ area
• Local bone sclerosis
• Elevation of the first ray
• Sesamoid hypertrophy
• Reduced 1 MTPJ dorsiflexion (weight- and non-weight-bearing)
• Reduced heel lift
• 1 MTPJ crepitus
Stage 3
Moderate structural HL
15-30° available dorsiflexion at 1 MTPJ
Structural loss of dorsiflexion at 1 MTPJ
• Pain within 1 MTPJ
• Marked 1 MTPJ deterioration
• Loss of 1 MTPJ space
• Extensive osteophytosis
• Bone sclerosis
• Cystic degeneration of subchondral bone
• Joint 'mice'
• Hypertrophy of sesamoids
• Elevation of the first ray
• Loss of height of MLA
• Decreased calcaneal angle
• 1 MTPJ crepitus
• Marked reduction of heel lift
Stage 4
Severe HR
<15° available dorsiflexion at 1 MTPJ
1 MTPJ immobility
• 1 MTPJ ankylosis and loss of joint space
• Marked osteophytosis and increased bulk of 1 MTPJ
• Loss of heel lift and/or hyperextension of IPJ of hallux

1 MTPJ, first metatarsophalangeal joint; MLA, medial longitudinal arch; IPJ, interphalangeal joint.

Functional assessment of bilateral wrist arthrodeses.
Furthermore, the total wrist arthrodeses were rated according to Buck-Gramcko and Lohmann (17) (9-10 = excellent, 7-8 = good, 5-6 = satisfactory, > 5 points = poor).
Four wrists were converted to total wrist arthrodeses after a mean time of 26 months (range: 8 to 44 months): two due to nonunion, one after infection, and another due to technical error.
There is ample evidence that many of the DBM products that are currently available are excellent graft substitutes especially when implanted into contained bone defects, fractures, or arthrodeses combined with stable internal fixation.
