5 The S2 Tibial Nails are cannulated, not slotted and have a fluted profile for an optimum bending addition, two longitudinal grooves ( one on each side of the nail ), between the 2 M/L Distal Locking Holes, are designed for the Distal Guided Locking Mode proficiency ( via S2 Distal Targeting Device ). The main principle of this proficiency is based on easy nail detection with a Probe inserted into this furrow. The rut is used to further guide the Probe into the Locking Hole. For detailed data about Distal Guided Locking Mode proficiency, please refer to the S2 Distal Targeting Device OP Technique, REF.

7 The S2 Distal Targeting Device offers the competitive advantage of : Eliminating the indigence for fluorosco-pic steering for the distal lock procedure Reducing the operative clock Easy calibration for each individual S2 detailed information about the Distal Targeting Device please refer to the S2 Distal Targeting Device Operative Technique, REF.

Pre-operative PlanningAn X-Ray Template, Tibia ( 1806-8008 ) is available for pre-operative planning ( Fig. ) 9 1 ) .Thorough evaluation of pre-operative radiogram of the affect extremity is critical. careful radiographic examen can prevent intra-operative standard mid-shaft fractures, the proper nail length should extend from barely below the Tibial Plateau at the appropriate mediolateral position to just proximal to the Epiphyseal Scar of the ankle : check with local representative regarding handiness of nail Indications8 Operative Technique4. Operative Patient Positioning and Fracture Reductiona ) The patient is placed in the supine position on a radiolucent fracture board and the leg is hyperflexed on the mesa with the aid of a leg holder, eyeball ) The leg is free-draped and hang over the border of the postpone ( Fig. 2 ) .The knee is flexed to > 90. A triangle may be used under the knee to accommodate inflection intra-opera-tively. 10 It is important that the stifle rest is placed under the back tooth aspect of the lower thigh in order to reduce the likely of vascular compaction and the risk of pushing the proximal frag-ment of the tibia decrease can be achieved by home or external rotation of the fracture and by grip, adduction or abduction, and must be confirmed under visualize intensification. Draping must leave the knee and the distal end of the leg IncisionA para-tendenous incision is made from the patella extending down approximately 4cm in planning of nail interpolation. The patellar Tendon may be retracted laterally or split at the junction of the median one-third, and late-ral two-thirds of the Patellar Ligament. This exposes the entrance sharpen ( Fig. 3 ) .Fig. 5 Fig. 6 Fig. 2 Fig. 3 Fig. Entry PointBased on radiological image, the medullary canal is opened through a superolateral tableland submission portal ( 2 ) .
