Ottawa Ankle Rules
The Ottawa Ankle Rules were developed to assist in making the decision to order an xray in a patient with ankle injury. X-ray examination is called
for if there is:
1. Pain around the malleolus
2. Inability to take weight on the ankle immedialtely after the injury
3. Inability to take four steps in Emergency Department
4. Bone tenderness at the posterior edge or tip of the medial or lateral malleolus or the base of the fifth metatarsal bone.
If x-ray examination is considered necessary, antero-posterior, lateral and 'mortise (30 degree oblique) views of the ankle should be obtained.

Angles in orthopedics

Normal is 20-40 degree, decreases

Synovial Fluid Analysis

• Normal synovial fluid is clear, WBC count ≤ 200/ uL
• Non-inflammatory synovial fluid is clear, viscous, amber colored with a WBC 200/ul-2000/uL and a predominance of mononuclear
cell.
• Inflammatory fluid is turbid, yellow, with an increased WBC count 2,000 to 50,000/uL and a polymorphonuclear leukocytic
predominance.
• Inflammatory fluid has reduced viscosity, diminished hyaluronic acid.
• Infections (pyogenic) is purulent, WBC count > 50,000/uL, PMN > 90% .
• Infections (Tuberculosis/granulomatous) is yellow, turbid, WBC count 10,000–20,000/uL, PMN 60% and presence of lymphocytes,
plasma cells and histiocytes.

CHARACTERISTIC DEFORMITIES OF HAND AND FOOT IN RA

'Z-deformity', i.e. radial deviation of the wrist with ulnar deviation of the digits, often with palmar subluxation of proximal phalanges.
Q
'Swan-neck deformity', i.e. hyperextension of PIP joints with compensatory flexion of the DIP joints.
Boutonniere deformity, i.e. flexion contracture of PIP joints and hyperextension of DIP joints. It is due to rupture of extensor tendon.
Hyperextension of 1st interphalangeal joint and flexion of MP joint with a consequent loss of thumb mobility and pinch—Swan Neck
deformity of thumb.
Eversion at hindfoot (subtalar joint), plantar subluxation of metatarsal heads, widening of forefoot, hallux valgus, and lateral deviation and
dorsal subluxation of toes; hammer toe (flexion of PIP).
Wind swept deformities of toes, i.e. valgus deformities of toes in one foot and varus in other (as wind sweeps all the structure in one
direction).

Pes Planus
• Flat foot refers to obliterated medial longitudinal arch.
• Heel is often in valgus called as planovalgus
• Pes Planus is of 2 types (Jacks test)
• Flexible : Disappears on non-weight bearing. Management is conservative
• Rigid : Due to Congenital Vertical talus or RA or Infection or tarsal coalition(AD-Talocalcaneal and calcaneonavicular) or
tibialis posterior dysfunction. They often require surgical intervention

b. Dwyer’s osteotomy of calcaneum is done to correct calcaneal varus in > 5 years.
5. 8–10 years Wedge Tarsectomy is done as deformity is more and requires multiple bones to be removed.
6. ³ 10 years
Triple arthrodesis is necessary for recurrent or persistent clubfoot deformity in older children (chronic cases). It is best done at > 10
years of age when foot growth is complete and the bones are ossified to achieve good fusion. It involves fusion of three joints: TN:Talo-
Navicular;TC:Talo-Calcaneal; CC: Calcaneo-Cuboid
