Abstract
Tennis elbow (latral epicodylitis) is a common problem that
causes many symptoms such as pain in lateral aspect of the elbow,
restriction of movement and impaired activities of daily life. There
are a lot of theories that explain the causes of that symptoms
such as the tendinogenic theory which relate the symptoms to
degeneration of the origin of the extensor carpi radialis brevis, the
articular theory which relate the symptoms to irritation of synovial
membrane secondary to weakened fibers of common tendon due to
trauma, stress or aging process, bursitis, traumatic periostitis and
chondromalecia of the capitulum lastly the neurogenic theory which
suggests an association between tennis elbow and entrapment of the
posterior interosseous nerve by a fibrous arch in the superficial head
of the supinator muscle (the arcade of Frohse) and the anterior aspect
of the deep apponeurosis of the extensor carpi radialis brevis.
Many modalities of treatment were prescribed to relieve the
symptoms such as rest, nonsteroidal anti-infl ammatory drugs
(NSAIDs), bracing, physical therapy and corticosteroid injection.
Newer treatment modalities have been tried, such as
extracorporeal shock wave treatment, iontophoresis, and injection of
botulism toxin.
In case of lack of response to conservative treatment, the last
resort is surgery with the primary objective of relieving pain. One
novel treatment strategy is the use of local injection of platelet rich
plasma.
Preparation of platelet-rich plasma involves centrifugation of
autologous blood to separate and concentrate platelets. The plateletrich
plasma fraction may then be activated prior to injection by
addition of excess calcium to saturate all platelet receptors.
Alternatively, the platelet-rich plasma fraction may be naturally
activated after injection when coming in contact with local tissues.
