Treatment The short-term aims of the treatment of

algodystrophy are the following: To relieve the pain. To correct or prevent vasomotor disorders. To prevent bone demoralization. To prevent trophic change and ankylosis. To reduce the duration of functional incapacity.

AD

Treatment

Medical treatment.

Local injections.

Sympathetic block.

Nerve block.

Physical and rehabilitation.

Accupuncture.

Psychotherapy.

Surgical treatment.

AD

Medical Treatment

NSAIDA.

Vasodilators.

Corticosteroids.

Betabolckers.

Calcitonin.

Calcitonin ( synthetic salmon Calcitonin)

Significantly shortens the duration of

functional incapacity, which can otherwise last for

a year or more, by preventing further bone

demineralization and promoting rapid

remineralization.

Is safe and well tolerated; there are known I

contraindications.

Calcitonin ( synthetic salmon Calcitonin)

Particularly when given in early-stage disease

Rapidly relieves pain, often completely.

Alleviates the other symptoms.

Increases joint mobility.

Definition "Algodyitrophy is a clinical syndrome characterized by prominent locoregional pain, vasomotor and trophic changes and delayed recovery, occurring after even minor trauma or surgery

Nomenclature of Algodystrophy

* Out of > 45 names the commonest are :- Algodystrophy

- Complex regional pain syndrome type 1 (CRPS1- port trauma or surgery)

- Complex regional pain syndrome type 2 (CRPS2- alter nerve Injury)

- Reflex sympathetic dystrophy

- Sudeks atrophy

Nomenclature of Algodystrophy* In retrospective studies the incidence

was:- 1-2% after various fractures and- 2-5% alter peripheral nerve Injury.

* In prospective studies, the incidence was much higher:- 7-3SV. of Colles' fracture ,- 27% after stroke with shoulder trauma and- 8%after stroke when shoulder trauma was avoided.

Associated events related to

Algodystrophy* Trauma:- without fracture

» minor trauma » major trauma

- withfracture» limbs » vertebra

* Neurological lesions* Spontaneous

* Other precipitating/ associated factors eg : - Surgery- Stroke - Coronary artery disease.

ADPathophysiology The clinical signs suggest the involvement of

the neurological system, and

The scintigraphic and radiological changes

indicate increased vascularity and accelerated

bone loss.

Which of the changes is cause or secondary

remains, however, to be proven.

ADPathophysiology The hypothesis of an abnormal sympathetic

nervous reflex Is, challenged by: The variable effect of local blockade of the sympathetic system

or of gympathectomy.

Furthermore, In a large group of patients with algodystrophy,

early symptoms of an exaggerated regional Inflammatory

response were found In most patients, but clinical symptoms of

a disturbance of the sympathetic nervous system, such as

hyperhydrosts, were only rarely present.

The lower level of noradrenallne In the affected site does not

support Increased sympathetic overactlvlty.

ADPathophysiology Tissue injury in the inciting event, and biochemical processes have

been involved.

Recently α-adrenerglc receptors have been emphasized, in controlling

thermoregulatory modulation.

Psychological symptomps were found in up to 50% of the patients,

BUT many of them were described in patients with severe illness as

well.

The changes in bone density on X-ray, with patchy osteoporosis, are

considered to be secondary to an inflammation-like component of the

syndrome and to disuse.

ADDIAGNOSIS No gold standard for diagnosis.

Diagnosis is based on the combination of clinical signs and in some,

cased by X-ray and radionuclide scintigraphic pictures.

In clinical research setting additional methods have been applied such as;

Thermography,

Volume measurement of the affected limb.

measurement of resting sweat.

Quantitative pseudomotor axon reflex tests.

Asymmetry, ultrasound, Doppler and bone densitometry.

RISK FACTORS FOR DEVELOPING ALGODYSTROPHY

Some studies, (thawed that Collet' fracture as evaluated by severity (usingthe Frytanan's dassHlcatton) will associated with the severity of algodystrophy.

Risk factor* alter itroke Included subluxation and paresis of the shoulder

girdle, moderate •pasticlty and vliual disturbances.

Transient osteoporosls of the hip Is a typical presentation hi pregnancy or

early postpartum.

The hypothesis of a special personality structure for developingaigodystrophy has not been found in a large overview of the literature.

Patients with severe complications were younger,

Females, had more often lower limb Involvement or multiple localizations and had Initially a 'cold* presentation on clinical examination.

Modified clinical diagnostic criteria Disproportionate pain to inciting event with:

- At least one symptom In each of the following categories:

• Sensory; hyperesthesla

• vasomotor : Temp. Asymmetry and /or skin colour changes and /or skin color asymm.

• Sweating /Oedema : Oedema and /or sweating changes and/or sweating asymm.

• Motor/ Trophic: Dei ease range of motion and /or motor dysfunction (weaqkness, tremor, dystonla) and / or trophic changes (hair ,nall, skin) B - Plus at least one sign In 2 or more of the same categories

Radionuclide scintigraphy Typically, the scintigraphic analysis includes a

radionuclide angiogram, a blood pool or tissue phase image and a delayed image.Three stages have been described

increased perfusion with increased and delayed activity of bone images, followed by.

Normal perfusion with persistent changes in bone images and lastly,

Normal or decreased vascularity with normalization of the bone images.

Typical positive image can be supportive but it’s the absence does not rule out typical clinical presentation.

Radionuclide changes Patchy or diffuse osteopenia are found in 50%

of cases.

The radiographic appearance is however non-specific.

Osteopenia may be seen 2 to 3 weeks after the onset of symptoms.

In a later stage: Affected bones may have a ground glass appearance.

Radionuclide changes (Cont.)

Localized osteoprosis :

After 7 weeks, bone loss was significantly highrt in

patients with alogodystrophy at cortical (14% versus-6%, P<

0.05) and trabecular sites ( -23% versus- 10% p< 0.001) in

the forearm compared to patients without algodystrophy.

in patient without algodystrophy, bone loss recovered

after 19-32 weeks, in patients with algodystrophy, bone loss

persisted after 6 to 12 months.

SPECTRUM OF CLINICAL SIGNS AND

SYMPTOMS Algodystrophy typical occurs in an extermity after a sometimes trivial event, such as trauma or surgry:

The clinical picture includes the combinations of

o intense pain that is disropportionate to the incting event.

o Vasomotor changes with oedema and changes in skin colour and

temperature.

o Delayed functional recovery, and

o Various associated tropic changes

The key feature is disroprotionate pain, and this may be the initial

manifestation of algodystrophy.

SPECTRUM OF CLINICAL SIGNS AND SYMPTOMS - The clinical picture of Algodystrophy is

different in children as compared to adults. It is

mostly characterised by hypothermia, and mild

and incomplete forms have been described

SPECTRUM OF CLINICAL SIGNS AND SYMPTOMS Stages of Algodystrophy :

Stage I (weeks to months):

o Non-focal pain of often progressively increasing intensity that is

disproprtionate to the incliting evevt, associated with joint stiffness,

decreased rang of motion, increased skin temperature and dyshydrosis.

Stage II (several months):

o Persisting pain with tendency to decrease in most but not all cases, oedema

with thicking of the skin and fascia, and muscular atrophy. Development of

localized patchy osteoporosis.

Stage III :

o Persisting, atrophy of skin and muscles, stiffness of the joint, cooling of the

involved extermity.

Long-term consequences

persists for > 1 year & may nead to loss of function

Bone loss Malunio Pain & stiffness

Deformity. Shortening of the radius.Radio-ulnar joint dislocation.

> 10% loss in cortical bone. > 25% loss in trabecular bone.

MANAGEMENT • Management of algodystrophy has been complicated by all the

above mentioned uncertainties

• Furthermore, management of chronic evolution can become

complicated by associated psychosodal problems of the

patient

• Physical therapy Is suggested as the mainstay of therapy, but

no controlled trial Is available,

• Caldtonln Induced a rapid decline In pain In 64% of patients

compared to 23% on placebo after 2 weeks (P < 0,001),

• Intranasal calcltonln was superior to placebo In ameliorating

pain and mobility, and resulted In Increased work ability after

60 days,

Miacalcic in Algodystrophy• Clinical Trial (Sawiki A. et al.1992):

* Synthetic Salmon Calcitonin is not only a po inhibitor

of the algodystrophic process but may also contribute

in some way to the activation of the skeletal

restoration of normal bone density.

* A marked clinical improvement occurred; pain

diminished, motion range increased oedema, redness
