Practical Examination Pes Cavus / Flat feet

know is it painful or not ?

and where is pain ?

         Talocalaneal coalition - medial side pain

         Calcaneonavicular Coalition - lateral side pain


Look -

           Standing - forefoot abducted , adducted - skew foot )

          hind foot - valgus

              bottom of foot - conved plantar surface - in rocker bottom foot

        shoulde be able to pass 2 fingers on medial arch.

        quickley see on lower back to see if there are any tell-tale signs.

Gait

 Tip toeing - flexible - heel varus ; medial arch prominent

 Tarsal Coalition - arch doesnot form , heel valgus


Sit - legs dangling

       check shoes

       more wear on medial side; if no wear ask if they are new.


Check Achilles tendon tightness -- stiff flat foot

ROM - Ankle and subtalar joint

            subtalar joint stiffness - difficult to illicit - patients will have ball and socket joint by   


            remodelling

 use IF/ Thumb to stabilize or at least to check talus body movement while  assessing subtalar joint



check neurovascular structures











Practical Examination - In-toeing and Out-toeing

After proper exposure from umbilicus to toes with an inner  wear


Check height and weight which might clue bony displasia or metabolic diseases


Gait - see foot progression angle (Angle between foot print and line of walking )

           normal angle is -5 to +20 degrees

          -5 to -10 mild , -10 to - 15 moderate

           > -15 degrees severe


Look - Leg length discrepancy , any noticeable deformities or muscles wasting

           Check Trendelenburg test during standing position


Feel - any tenderness on soft tissue or bony tenderness

Movement


Special test on prone position with a pillow on chest

 Hip rotation

          Knee in 90 degree flexion , check Hip IR and ER

      Normally Hip IR < 70 degrees , ER < 30 degrees

         meausre Anteversion angle

            Birth ; 40 degrees

            9 years  ; 20 degrees

           16 years ; 16 degrees


    Thigh foot angle

      normally ; 0-20 degrees

      measure tibial and hind foot rotational status


  Transmalleolar thigh angle

         measures tibial torsion only

        normally 0 -40 degrees  .



suspect any pathology when there is

  pain , limp , LLD , asymmetry , rapid changes in rotational profile.








   


Rehabilitation phase weight bearing

It depends on quality of bone , gemoetry of fracture and type of implant used.


Wight bearing not allowed immediately in

  Uncemented THR

  Plate fixation

  Locking Plate

Wight bearing allowed immediately

  Nailing

  TBW

   External Fixator application

   Cemented THR

   Pedicle Screw fixation

Practical Examination - Flexor Tendon Injury

Examination depends on the question given. May be examination of the whole extremity or just the

hand . Be careful !

Exaimination begins after asking 2 questions as allowed . Relevant questions might be after your 

own  introduction .

 1. what happened ?

 2.when did it happen ?

one can ask hand dominance and profession during examination to be clever .

Then get permission from patients


If command is to examine the whole upper extremity go as below


Look - Normal alignment of Right Upper extremity

            shoulder at slight abduction

           elbow flexed, forearm supinated with palm facing up

            cascade of fingers not maintained , index finger is extended while others are in flexion

           no wasting of muscles on arm , forearm , hand on volar and dorsum side

          on hand , there is a transverse scar around 1 cm proximal to metacarpophalangeal joint ,

           healed.

           color of all fingers look pink on finger tips as  well as nail bed

Feel - temperature normal

          no soft tissue , bony tenderness

          sensation- ulnar / median / radial nerve is intact

                           digital nerve sensation - intact


Pulsation - Allen's test for fingers

                  tinel's test for nerve injuries

Lymph nodes palbable or not 

Movement - screening quickly active motion of shoulder , elbow and wrist

                   Finger passive active and passive test at PIP , DIP and MCP

Tests for

 FDP of all fingers , FDS of all fingers , Extensor , Adductor ,abductors of fingers


Mention diagnosis as

 Flexor Tendon Injury Rt. RF Zone III (Mention the duration of injury in weeks )



Investigations

MRI - to confirm diagnosis

           to document the injury

           proximal tendon level will be identified in old cases

X-ray - to see joints ,
 
            if there is bony injury as well


Treatment

 Physiotherapy to make skin supple , prevent joint stiffness


Surgery

    Primary Repair - done within a week

     Delayed Primary Repair - done within 14 days

    Secondary Repair - 2-5 weeks

    Delayed Secondary - after 5 weeks .

       ossification and healing of inferomedial fragment

       restore Articular Trochanteric distance and abductor mechanism

       to resotre length- tension relationship

        abduction tenotomy

        Osteotomy - 3 types

                       1. Pauwel's Y-shpaed

                        2. Langenskiold Intertrochanteric Osteotomy

                       3. Borden subtrochanteric Osteotomy



Median Nerve Examination

Not to miss following points during the examination

Attitute of the limb or hand

cascade of fingers


Look -
           any scars on arm , forarm

       wasting on forearm and thenar region


Feel - temperature

           any soft tissue or bony tenderness

           tinel's sign ,scar tenderness , scar pliability

           lymph nodes



Movement

          active and passive -rapidly test it

Measurement if any angulation or bony deformity or bony shortening


Neurovascular examination

sensation of autonomous zones of hand and  direct the examination to the nerve affected

Power of muscles - Examine both the weaker muscles and donor group of muscles


Forearms - Brachioradialis , Pronator Teres , Supinator

           
Wrist      FCU, FCR , PL,Pronator Quadratus , ECRL


Hand       FDS

                FDP , FPL

               Lumbricals

              Opponens Pollicis

              Abductor Pollicis Brevis

             FPB


Reflexes

Pulsation and Allen's test




History of injury, scars or muscle wasting supplied by median nerve , loss of sensation and muscle

weakness suggest median nerve injury.

How do you treat them ?

It's treated same as other nerve injuries. See on previous section for nerve injuries management.


Its true for all other nerves.


If time period of nerve repair does not allow then tendon transfer is an option.



What are choices for tendon repairs in Median nerve injury ?


High Median Nerve Injury


losses - Forearm pronation

             radial flexion of wrist

             thumb flexion

            2nd and 3rd finger flexion

            opponens function of thumb

           
Choices of tendon to supplement the function
           

        Brachiolradialis to FPL

        EIP to Opponens Pollicis

        FDP to 2nd and 3rd finger

       sensory flap for thenar region



pnemonic for tendon options - BEF


Low Median Nerve Injurry 

losses - Opposition

            sensation of thenar region

Donor tendons
   
 EIP , PL and FDS RF

Mnemonic  -      PEF



Never forget Post operative physiotherapy after tendon transfer.

          suture removal after 3 weeks

          splint removal in 3 weeks

          start training like pen holding in 3 weeks

          eating with the hand after 4 weeks

          heavy work not done till 2 months after surgery
