AO Principles
In 1958, the AO formulated four basic principles, which havebecome the guidelines for internal fixation.1,2 These principles,as applied to the Angular Stable Locking System (ASLS), are:
Anatomic reductionSynthes IM nails are designed to anatomically fit in themedullary canal, allowing indirect reduction. ASLS reducesthe chance of secondary loss of reduction by providing axialand angular stability.
Stable fixationASLS provides angularly stable fixation between nails andscrews by using resorbable sleeves as dowels in the nail locking holes. The principals of relative stability achieved with intramedullary nailing are still valid with ASLS.
Preservation of blood supplyThe ASLS is used in conjunction with Synthes intramedullarynails which facilitate a percutaneous insertion technique. A percutaneous insertion technique may result in less tissuestripping and resultant vascular trauma than other methods.
Early, active mobilizationThe ASLS is designed to improve angular and axial stability.The stable fixation of fractures may be conducive to optimalrecovery by permitting controlled, early, active rehabilitation.

4 Synthes Angular Stable Locking System (ASLS) Technique Guide
Indications
The Synthes Angular Stable Locking System (ASLS), whenused with Synthes cannulated titanium intramedullary nails,is intended to aid in the alignment and stabilization of tibial,humeral, femoral and ankle fractures.
Synthes 5
Preparation
The following pages describe techniques for locking withASLS. All illustrations use the Tibial Nail-EX, as an example.
1Preoperative planning
Use the appropriate AO preoperative planner template to estimate nail diameter and length.
2Reduce fracture and insert nail
Reduce the fracture and insert the nail. Use a compatibleSynthes titanium cannulated intramedullary nailing systemaccording to the relevant technique guide.
Note: The ASLS is only compatible with cannulated nails. It is necessary for the sleeve to expand within the cannulationof the intramedullary nail to provide sufficient stability.
6 Synthes Angular Stable Locking System (ASLS) Technique Guide
3Choose appropriate locking screws
For each locking hole, preselect the optimal locking implantto stabilize the fracture. If using an ASLS screw, the diameterof the ASLS screw and instruments will match the diameterof the standard screw/bolt for the particular nail.
Note: A combination of standard locking screws/bolts andASLS screws can be used in the same nail.
Caution: Do not exchange a standard locking screw/bolt foran ASLS screw or vice versa as this may reduce screw-to-boneinterface stability.

Screw Insertion
1Position sleeve
Select the appropriate resorbable sleeve.
Position the sleeve so that the sleeve lip is facing thescrewhead. Thread the ASLS sleeve onto the ASLS screw.
Note: The sleeve is positioned correctly when gold is visibleon either side of the sleeve and the screw tip protrudes 1 mm–2 mm beyond the sleeve.
Caution:Do not use ASLS screws without sleeves.
When attaching the sleeve, stop threading the sleeve onceresistance increases. Resistance occurs when the sleeve expands as it moves onto the larger diameter of the screw.An expanded sleeve will prevent screw/sleeve insertion into a locking hole.
