By Chart Clinic Osteopath, Pavlos Pavlidis MOst.Med.
Hello
everyone,
My name is
Pavlos and I am a new member of the Chart clinic. I am a qualified Osteopath
and have received a Masters degree in Osteopathic Medicine with First class
honours.
In this
article I will attempt to provide some insight for “Sciatica”, a term commonly
used between clinicians as well as patients. However, it is also being commonly
misused, especially by the latter.
In this
article I will describe the meaning of this term in order to promote a better
understanding. I decided to write this after many cases of patients that
presented to our clinic thinking that they have “Sciatica” while in fact they
did not.
To begin
with the origin of the word “sciatica”, it derives from the Greek Ischialgia, with Ischio: Hip and Algos:
Pain, and literally translates as Hip
pain. In clinical practice it is commonly used to describe pain that
radiates along the Sciatic nerve, usually as a result of compression at the
lower back.
Now let’s
get a closer look at the anatomy. The roots of the sciatic nerve exit from the
space between the last two bones in the lower back vertebrae and the first
three of the “tailbone” or sacrum as it is known to us, clinically referred to
as nerve roots of lumbosacral plexus L4-S3.
It then
travels to the buttock and back of the thigh area and divides into two branches at the back of the knee that goes all the way to the leg and foot. The Sciatic
is the longest nerve in the human body and along with its branches supplies the
majority of muscles at the back of the thigh, leg and foot. Furthermore, its
branches provide sensation to the skin at the back and outside portion of the
leg, as well as the top and bottom aspect of the feet.
Therefore,
when this goes wrong or you get a dysfunction of this nerve can lead to weakness
of the above-mentioned muscles as well as burning pain, pins and needles or
numbness to the back of the leg and foot.
(Note that
any symptoms at the groin, front of the thigh or leg ARE NOT associated with
the sciatic nerve and Sciatica would be completely inappropriate to describe
them)
The term
“Sciatica” describes any of the symptoms caused as a result of injury or
compression to the nerve and therefore it represents a group of symptoms and
NOT a diagnosis. There are numerous causes
of impairment of this nerve and its brunches, anywhere from its roots exiting
the lower back to the lower limb. Some of the common causes include severe
arthritis of the lower back, a “slipped disc” – a protrusion of the discs in
the spine that compresses its roots, or tight muscles at the buttock (such as
the piriformis muscle) and back of the thigh, as the nerves passes through them.
Nevertheless, there are also some rare but potentially life-threatening causes
of sciatic nerve impingement.
Therefore, it is extremely important for anyone
presenting with such symptoms to be properly examined by a clinician so a
specific and appropriate diagnosis can be made.
Due to the
variety of symptoms caused by dysfunction of this nerve and the numerous causes
of it, it is often misused by patients that tend to use it to describe any low
back pain that radiates downwards. However, self labeling must be avoided
before a proper examination and diagnosis by a qualified practitioner, as it
can be associated with diagnostic errors, misdiagnosis and therefore
mismanagement.
Nowadays,
the term has been labeled as “Archaic”, as it is non-evidence based and
inaccurate as it literally translates to hip pain. The literature suggests that
it remains from an era of poor understanding of the physiology of back pain.
To
conclude: “Sciatica” is a generalised and non-descriptive term, as various
conditions might lead to irritation of the sciatic neural tissue, in multiple
anatomical sites with different presentation of symptoms.
Patients
must avoid using this term and self-labeling themselves, especially if
appropriate examination and diagnosis has not been carried out. Patients that
experience any of the symptoms described are highly advised to seek help from a
clinician with experience working on the musculoskeletal system to exclude any
dangerous causes for that and provide appropriate diagnosis and management
plan. This includes Osteopaths, Physiotherapists, Rheumatologists, Orthopaedic
surgeons etc.
Please do
not hesitate to contact me or any of my colleagues for any further information
or advice concerning “Sciatica” or any other condition.

Pavlos qualified in 2017
and received a Masters Degree with First class honors from the University of
Surrey. During his time as a
student he demonstrated a great passion for the profession, both in academic
and clinical settings and was awarded with the Rising Star Award from the
Institute of Osteopathy.
In practice, he follows a multidisciplinary and
personalised treatment approach, tailor-made for the needs of the patient. Pavlos has undertaken additional qualifications in Kinesio
taping and Medical Acupuncture. Those extra skills have been found to be
extremely useful in practice, as they provide additional treatment options,
especially useful for pain management and rehabilitation.
