Indications

 

Deformity correction

 

TSF Deformity Correction Proximal Tibial Fracture Preop

 

Technique

 

Apply proximal and distal rings

- choose size

- 2 cm from skin all around

- leg will often swell

- most often compression is posterior

- can use an open ring proximally to aid knee flexion

 

Apply proximal rings

- Centre / Master Tab anterior to tibial crest

- important for calculations

 

Apply Distal ring

 

6 x adjustable struts

- come in 3 lengths (short / medium / long)

- need to ensure that are long enough for any correction

- otherwise will have to adjust strut later

- numbered 1 - 6

- no 1 always to right of proximal strut

 

TSR Clinical Photo Struts

 

Intra-operative Correction

- can perform

- new computer program

- struts can be of different lenths

- i.e. the rings do not have to start perpendicular to shaft

 

Record numbers of each strut

- important for computer calculation

 

TSR Strut Measurements Pre Correction

 

Post operative Xray Measurements

 

Xray of entire tibia and rings

- xray centred on proximal tab of proximal ring

- AP and Lateral all in one film

- the entire diameter of the rings must be on the film

 

Set reference fragment

 

Proximal tibia

- usually the proximal fragment is reference fragment

- distal fragment is moving fragment

 

TSF Reference and Moving Fragment

 

Opposite for Distal Tibial Fractures

 

Set Origin / Corresponding Point on AP and Lateral

 

Origin

- reference fragment

 

Corresponding point

- on moving fragment

 

TSF Origin and Corresponding Point

 

Measure AP and Lateral View Axial Frame Offset

 

The tibia is not in the centre of the rings

- usually anterior

- need to tell computer where the proximal fragment is in reference to the rings

 

TSF AP View Frame OffsetTSF Lateral View Frame Offset

 

Estimate Rotatory Offset

 

If Proximal Ring Tab not centred over anterior border of tibia

- need to clinically estimate the difference

- i.e. 5o

 

Characterise the skeletal deformity

 

6 measurements required

 

AP View Angulation + Translation

 

TSF AP View Angulation and Translation

 

Lateral View Angulation + Translation

 

TSF Lateral View Angulation and Translation

 

Axial Translation (Shortening)

 

TSF Axial Translation

 

Axial View Angulation

 

Clinical

- is the foot externally rotated

- if so, how much

 

Total Residual Correction

 

Enter details

- ring size

- strut length

- reference fragment / origin

- frame offset

- 6 measurements

 

Tell rate of correction

- usually 10 days to 2 weeks

 

Computer will calculate correction

- assumes correct to neutral

- print daily strut changes requires
