 Why does this gal have so much limited external rotation of her legs? 

 We have discussed torsions and versions here on the blog many times before. We rarely see femoral antetorsion. She came in to see us with the pain following a total hip replacement on the right.

 Note that she has fairly good internal rotation of the hips bilaterally but limited external rotation. This is usually not the case, as most folks lose internal rotation. We need 4 to 6° internal and external rotation to walk normally. This poor gal has very little external rotation available to her.

Have you figured out what’s going on with hips yet? She has a condition called femoral ante torsion.   This means that the angle of the femoral neck is in excess of 12°. This will allow her to have a lot of internal rotation but very little external rotation.  She will need to either “create” or “borrow” her requisite external rotation from somewhere. In this case she decreases her progression of gait (intoed), and borrows the remainder from her lumbar spine.

 So what do we do? We attempt to create more external rotation. We are accomplishing this with exercises that emphasize external rotation, acupuncture/needling of the hip capsule and musculature which would promote external rotation (posterior fibers of gluteus medius,  gluteus maximus, vastus medialis, biceps femoris). A few degrees can go a very long way as they have in this patient.

 Every foot has a story. 

 This is not your typical “in this person has internal tibial torsion, yada yada yada” post.  This post poses a question and the question is “Why does this gentleman have a forefoot adductus?”

The first two pictures show me fully internally rotating the patients left leg. You will note that he does not go past zero degrees and he has femoral retroversion. He also has bilateral internal tibial torsion, which is visible in most of the pictures. The next two pictures show me fully internally rotating his right leg, with limited motion, as well and internal tibial torsion, which is worse on this ® side

 The large middle picture shows him rest. Note the bilateral external rotation of the legs. This is most likely to create some internal rotation, because thatis a position of comfort for him (ie he is creating some “relief” and internal rotation, by externally rotating the lower extremity)

 The next three pictures show his anatomically short left leg. Yes there is a large tibial and small femoral component. 

 The final picture (from above) shows his forefoot adductus. Note that how, if you were to bisect the calcaneus and draw a line coming forward, the toes fall medial to a line that would normally be between the second and third metatarsal’s. This is more evident on the right side.  Note the separation of the big toe from the others, right side greater than left. 

Metatarsus adductus deformity is a forefoot which is adducted in the transverse plane with the apex of the deformity at LisFranc’s (tarso-metatarsal) joint. The fifth metatarsal base will be prominent and the lateral border of the foot convex in shape . The medial foot border is concave with a deep vertical skin crease located at the first metatarso cuneiform joint level. The hallux (great toe) may be widely separated from the second digit and the lesser digits will usually be adducted at their bases. ln some cases the abductor hallucis tendon may be palpably taut just proximal to its insertion into the inferomedial aspect of the proximal phalanx (1)

Gait abnormalities seen with this deformity include a decreased progression angle, in toed gait, excessive supination of the feet with low gear push off from the lesser metatarsals. 

 It is interesting to note that along with forefoot adductus, hip dysplasia and internal tibial torsion are common (2) and this patient has some degree of both. 

 His forefoot adductus is developmental and due to the lack of range of motion and lack of internal rotation of the lower extremities, due to the femoral retrotorsion and internal tibial torsion.  If he didn’t adduct the foot he would have to change weight-bearing over his stance phase extremity to propel himself forward. Try internally rotating your foot and standing on one leg and then externally rotating. See what I mean? With the internal rotation it moves your center of gravity over your hip without nearly as much lateral displacement as would be necessary as with external rotation. Try it again with external rotation of the foot; do you see how you are more likely displace the hip further to that side OR lean to that side rather than shift your hip? So, his adductus is out of necessity.

Interesting case! When you have a person with internal torsion and limited hip internal rotation, with an adducted foot, think of forefoot adductus!

More on the “little guy”

We have been following this little guy for some time now. If you have not been keeping up, perhaps you should read herehere and here 1st. 

So, what do we see in these latest pictures?

Top left: neutral view.

  • He enjoys flip flops; probably not the best thing for a developing kiddo, in light of the excessive engagement of the posterior compartment (and reciprocal inhibition of the anterior compartment)
  • he has some tibial varum (ie bowleggedness) L > R
  • he has some developmental genu valgum whnich appears to be improving (need a Q angle review? click here)
  • no tibial torsion present on L: for a review on torsions, click here
  • still some external tibial torsion present on R (see section below on middle shots)

Top right and bottom: full internal rotation of R thigh: compare with bottom: full internal rotation of L thigh

  • he has adequate internal rotation (4 degrees needed) but not as great as left side (see bottom shot); this represents some improvement since we started
  • he has generous internal rotation of the left thigh

Middle Left: full external rotation of right thigh

  • note the position of the knee and the position of the foot; external tibial torsion is present. for a review of torsions, click here.
  • he has limited external rotation of the right thigh (compared with the left. The knee should fall more outside the saggital plane

Middle right: full external rotation of the left thigh

  • note the position of the knee and the position of the foot; internal tibial torsion is present. 
  • he has generous external rotation of the left thigh (compared with the left)


of other significant note: most of his calcaneal valgus has resolved; longitudinal arches are improved.

What now?

  • He continues to develop normally and continues to improve since his original presentation to the office
  • Having the child continue to walk barefoot
  • Continue to wear shoes with little torsional rigidity, to encourage additional additional intrinsic strength to the feet
  • He should continue to limit “W” sitting, as this will tend to increase the genu valgus present
  • We reviewed 1 leg balancing “games” and encouraged continuing agility activities, like balance beam, hopping, skipping and jumping on each leg individually
  • added in using a push and pedal bike
  • added in heel walking exercises

Subtle clues. Helping someone around their anatomy

This patient comes in with low back pain of years duration, helped temporarily with manipulation and activity. Her exam is relatively benign, save for increased lumbar discomfort with axial compression in extension and extension combined with lateral bending. Believe it or not, her abdominal and gluteal muscles (yes, all of them) test strong (no, we couldn’t believe it either; she is extremely regular with her exercises). She has bilateral internal tibial torsion (ITT) and bilateral femoral retro torsion (FRT). She has a decreased progression angle of the feet during walking and the knees do not progress past midlilne. There is a loss of active ankle rocker with gait, but not on the exam table; same with hip extension. 

We know she has a sweater on which obscures things a bit, but this is what you have to work with. Look carefully at her posture from the side. The gravitational line should pass from the earlobe, through the shoulder, greater trochanter and through or just anterior to the lateral malleolus.

In the top picture, can you see how her pelvis is anterior to this line? Do you see how it gets worse when she lifts her hands over her head (yes, they are directly over head)? This can signify many things, but often indicates a lack of flexibility in the lumbar lordosis; in this case, she cannot extend her lumbar spine further so she translates her pelvis forward. Most folks should have enough range of motion from a neutral pelvis and enough stability to allow the movement to occur without a significant change. Go ahead, we know you are curious, go watch yourself do this in a mirror and see if YOU change.

Looking at the bottom left picture, can you pick out that she has a genu valgus? Look at the hips and look at the tibial angle.

In the bottom left picture, did you note the progression angle (or lack of) in her feet? This is a common finding (but NOT pathognomonic) in patients with internal tibial torsion. Notice the forefoot adductus on the right foot?

So what do we think is going on?

  • ITT and FRT both limit the amount of internal rotation of the thigh and lower leg. Remember you NEED 4 degrees of each to walk normally. Most folks have significantly more
  • if you don’t have enough internal rotation of the lower extremity, you will need to “create” it. You can do this by extending the lumbar spine (bottom picture, right) or externally rotating the lower extremity
  • Since her ITT and FRT are bilateral, she flexes the pelvis and nutates the pelvis anteriorly.
  • the lumbar facet joints should only carry 20% of load
  • she is increasing the load and causing facet imbercation resulting in LBP.

What did we do?

  • taught her about neutral pelvic positioning, creating more ROM in the lumbar spine
  • had her consciously alter her progression angle of her foot on strike, to create more available ROM in internal rotation
  • encouraged her to wear neutral shoes
  • worked on helping her to create more ankle rocker and hip extension with active drills and exercise (ie gait rehabilitation); shuffle walks, Texas walk, toes up walking, etc

why didn’t we put her in an orthotic to externally rotate her lower extremity? Because with internal tibial torsion, this would move her knee outside the saggital plane and create a biomechanical conflict at the knee and possibly compromising her meniscus.

Cool case, eh? We thought so. Keep on learning so your brain keeps expanding. If you are not growing your brain, you are shrinking it!

You can only “borrow” so much before you need to “pay it back”

How can feet relate to golf swing?

This 52 year old right handed gentleman presented with pain at the thoracolumbar junction after playing golf. He noticed he had a limited amount of “back swing” and pain at the end of his “follow through”.

Take a look a these pix and think about why.

Hopefully, in addition to he having hairy and scarred legs (he is a contractor by trade), you noted the following

  • Top left: note the normal internal rotation of the right hip; You need 4 degrees to walk normally and most folks have close to 40 degrees. He also has internal tibial torsion.
  • Top right: loss of external rotation of the right hip. Again, you need 4 degrees (from neutral) of external rotation of the hip to supinate and walk normally.
  • Top center:normal internal rotation of the left hip; internal tibial torsion
  • 3rd photo down: limited external rotation of the left hip, especially with respect ti the amount of internal rotation present; this is to a greater degree than the right
  • 4th and 5th photos down: note the amount of tibial varum and tibial torsion. Yes, with this much varum, he has a forefoot varus.

The brain is wired so that it will (generally) not allow you to walk with your toes pointing in (pigeon toed), so you rotate them out to somewhat of a normal progression angle (for more on progression angles, click here). If you have internal tibial torsion, this places the knees outside the saggital plane. (For more on tibial torsion, click here.) If you rotate your extremity outward, and already have a limited amount of range of motion available, you will take up some of that range of motion, making less available for normal physiological function. If the motion cannot occur at the knee or hip, it will usually occur at the next available joint cephalad, in this case the spine.

The lumbar spine has a limited amount of rotation available, ranging from 1.2-1.7 degrees per segment in a normal spine (1). This is generally less in degenerative conditions (2).

Place your feet on the ground with your feet pointing straight ahead. Now simulate a right handed golf swing, bending slightly at the waist and  rotating your body backward to the right. Now slowly swing and follow through from right to left. Note what happens to your hips: as you wind back to the right, the left hip is externally rotating and the right hip is internally rotating. As you follow through to the left, your right, your hip must externally rotate and your left hip must externally rotate. Can you see how his left hip is inhibiting his back swing and his right hip is limiting  his follow through? Can you see that because of his internal tibial torsion, he has already “used up” some of his external rotation range of motion?

If he does not have enough range of motion in the hip, where will it come from?

he will “borrow it” from a joint more north of the hip, in this case, his spine. More motion will occur at the thoracolumbar junction, since most likely (because of degenerative change) the most is available there; but you can only “borrow” so much before you need to “Pay it back”. In this case, he over rotated and injured the joint.

What did we do?

  • we treated the injured joint locally, with manipulation of the pathomechanical segments
  • we reduced inflammation and muscle spasm with acupuncture
  • we gave him some lumbar and throacolumbar stabilization exercises: founders exercise, extension holds, non tripod, cross crawl, pull ups
  • we gave him foot exercises to reduce his forefoot varus: tripod standing, EHB, lift-spread-reach
  • we had him externally rotate both feet (duck) when playing golf

Well, how convenient.  A fantastic picture for teaching from the cover of one of our favorite magazines. 
 For this post, lets start with the gal on the left in the pink shirt. 1st of all, she is running in flip flops. Since these require so much long flexor activity to keep them on, not the best footwear choice, in our opinion. Check out that exaggerated left sided arm swing. This goes to propel herself forward. Why the extra effort? Check out her right (stance phase leg). What do you see? The knee points outward while the foot is planted. We are looking at either external tibial torsion or a femoral retrotorsion. Did you pick up the compensatory head tilt to the left? The vestibular system has become involved, and the trapezius and levator scapula seem to be it’s target (thus the shoulder hike and ipsilateral rotation), as well as the ipsilateral lateral benders and rotators of the cervical spine, namely the splenius cervicis and capitis (the multifidus/rotatores are contralateral rotators). 
 How about the subtle pelvic shift to the right? and the mild crossover gait (note the adduction of the left knee across midline). 
 It would be great to see a shot of her barefoot to see what changes, as increased long flexor activity has both local (impaired ankle rocker, excessive forefoot inversion, reciprocal inhibition of the anterior compartment muscles of the lower leg) as well as long distance (namely increased flexor drive to the brainstem and cerebellum) implications. We would want to see this (as well as examine her) before making any recommendations other than LOSE THE FLIP FLOPS GIRLFRIEND. 
 Wow, all that and we have only scratched the surface.

Holy Late Cretaceous Therapods. Those Veliciraptors were twisted!

The dinosaur made famous by Jurassic Park (We never understood why they put this dinosaur in the movie, the Jurassic period was many millions of years earlier, but that’s another story).

Dr Ivo was able to take some pictures of a rare, preserved skeleton from Mongolia at the dinosaur museum in Fruita, CO, while visiting with his family.

These bad boys (and girls) were fast predators, and one of the things that made them that way, was the fact that they were built for speed!

Take a look at theses hips! Note the extreme retro torsioned angle of the femur heads. We remember that femoral retro torsion limits internal rotation of the hips (OK, so you don’t remember? click here for a review).

Now lets think about this. Externally rotate your thigh and lower leg. What do you notice? Hopefully you notice it puts your foot in more supination. This makes it into a more rigid lever, better for pushing off and better for sprinting!

Have you ever seen a sprinter? do they run on their toes? Is their foot more supinated? Ever see a velociraptor run? Check out this sequence from the “Dinosaur Planet” series. Remember, only their toes are on the ground and the thing that looks like a backwards knee is actually their ankle. 

Since their legs are so close to the body, there is little need for internal rotation, so why not maximize the effect and assist in supination?

Wow! Are you finally convinced that torsions are cool? After all, they appear to have been around for at least the last 75 million years and probably longer.
