Congenital Talipes Equinovarus(Clubfoot)



The term talipes is derived from of the Latin words for ankle(talus) & foot (pes).

The term refers to the gait of severely affected
patients, who walked on their ankles.
  • Clubfoot  is a severe fixed deformity of the foot characterized by fixed ankle plantar flexion (equinus), inversion of the subtalar (talocalcaneal) joint (varus), and medial subluxation of the talonavicular and calcaneocuboid joints (adductus)
Etiopathogenesis 
  • Idiopathic majority , some  secondary to muscle pathology 
  • All the tissues of the foot i.e. bone, joint,ligaments and muscles have developmental abnormality
  • Bone: smaller in size, neck of talus is angulated so that head of talus is directed downwards  and medially. Calcaneum is small and concave  medially
  • Joints: equinus deformity  occurs primarily at ankle joint. Inversion deformity occur  in subtalar joint. Adduction occurs in midtarsal joints
  • Muscles and tendons: muscles of calf are underdeveloped.
  • Capsule and ligament: all the ligamentous structure on the postero-medial side of the foot shortened
  • Skin shows adaptive change
  • Callosities and bursae over  bony prominences on the lateral side
Congenital Talipes Equinovarus
  • Bilateral in 60%. 
  • General examination to rule out other deformities
  • Normally, the foot of newborn can be dorsiflexed until the dorsum touches the anterior aspect of shin of tibia
  • Components of the deformity:
  • Equinus.
  • Varus.
  • Adduction.
X-ray
  • AP view and a lateral view in a position of maximum dorsiflexion. 
  • Kite angle is the angle subtended by the long axes of the calcaneus and the talus on the AP view. 
  • This angle is normally between 20 and 40 degrees. 
  • In the clubfoot, this angle is less than 20 degrees with relative parallel alignment of the talus and calcaneus. 
  • The relationship of the talus and calcaneus should also be assessed on the lateral view. Again, in the clubfoot, this shows relative parallel alignment compared with the normal foot



Treatment 
Nonoperative :
  • Best results are achieved with early manipulation.
  • (as early as first week of life) and serial casting (changed every 2 week).  Adduction deformity is corrected first followed by inversion and then equinus deformity. If this sequence is not followed rocker bottom foot may result 



Wearing Of Dennis-Browne(DB) splints for maintenance.


Good results may be achieved if previous technique is applied.


Operative Technique :
  • In less than 3 years only soft tissue release may be sufficient while older children require  bony operations.
  • Indicated for manipulation failure cases, recurrence and neglected cases
  • Posteromedial soft tissue release (PMSTR)
  • Tendon transfer
  • Dwyer’s osteotomy- open wedge osteotomy  of calcaneus
  • Dilwyn-Evan’s procedure : PMSTR with calcaneo-cuboid fusion
  • Wedge tarsectomy
  • Triple arthrodesis

What are the clinical manifestations of spongiform encephalopathies?


1. Creutzfeldt-Jakob disease CJD :85% cases are sporadic; 15% are familial

2.Middle age to elderly patients

3.Rapidly progressing dementia 

4.Memory loss with startle myoclonus or other involuntary movements

5.Typical EEG changes

6.Death within 6-12 months.

  • Neuromuscular disorders (cerebral palsy, Duchenne's Muscular Dystrophy)
  • Discitis
  • Juvenile rheumatoid arthritis
5 to 10 years old
  • Septic arthritis
  • Osteomyelitis
  • Transient synovitis
  • Perthes
  • Limb length difference
  • Tumor (ALL, Ewing sarcoma, benign bone tumors)
  • Neurologic disorders (hereditary motor sensory neuropathy)
  • Discitis

10 to 15 years old
  • Osteomyelitis
  • Slipped capital femoral epiphysis (SCFE)
  • Tumor (osteosarcoma, Ewing's sarcoma, benign bone tumors)
  • Perthes disease
  • Hip dysplasia
  • Idiopathic chondrolysis

History
  • Acuteness of onset, pain, history of trauma or injury, constitutional symptoms such as fever, malaise, chills; early morning stiffness and motor milestone development (walked by 15-18 months).
  • Past medical history, Birth history and any previous surgery, injuries, or illnesses.
  • Family history of childhood lower extremity conditions such as developmental dysplasia of the hip (DDH).
Physical examination
  • An antalgic gait is characterized by a decreased stance period on the affected limb as well as a trunk shift over the affected limb during stance.
  • Evaluation for limb length difference: palpate the anterior superior iliac spine (ASIS) with the patient standing. Then, with the patient supine, compare lengths of the lower extremities with the legs extended. Also, compare lengths of the femurs by flexing the hips and comparing the relative heights of the knees.
  • Physical exam should also include the back, sacroiliac (SI) joints, and abdomen as well as the entire extremity involved.
  • Palpate the entire length of the limb.
  • Range of motion of the hip, knee, and ankle joints. Particular attention should be paid to any erythema, warmth, joint effusion, or focal tenderness.
  • A thorough neurologic examination should also be completed.
Investigation 
  • Radiographic evaluation. Anteroposterior (AP) and lateral plain radiograph (x-ray) of the entire length of bone involved, including joint above and below the area of concern. Referred pain describes pain attributed to one site or location by the patient but the source of the pain is at a different site (e.g., knee pain in a patient with an SCFE involving the hip joint). 
  • Laboratory studies. Complete blood count (CBC) with differential, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). If rheumatologic conditions or spondyloarthropathies are being evaluated, include rheumatoid factor (RF), antinuclear antibody (ANA), anti-streptolysin (ASO) titer, Lyme titer, and HLA B-27.
  • Additional imaging studies.
  • Magnetic resonance imaging (MRI). Very sensitive and specific. Able to identify areas of bone marrow edema, soft tissue edema, or fluid collections such as abscesses.
  • Ultrasound. Useful to look for hip joint effusions, subperiosteal or soft-tissue abscesses. May also help guide aspiration of hip joint or soft tissue abscess.
  • CAUTION: If septic arthritis is suspected, a joint aspiration should be performed without wasting time waiting for the availability of other additional imaging studies.
