  • No tool required to mount to any MAYFIELD® base unit.
  • Head supports can be adjusted vertically and laterally for flexibility in patient positioning, then locked in place.
  • Position of head support can be tilted on ball socket joint and locked in place.


MAYFIELD® Infinity Horseshoe Headrests – Adult (S419A1031) / Pediatric (S419A1030)

  • Provide non-invasive cranial support for adults, children and infants in either prone or supine positions.
  • Adjustable pad base (faceplates) accommodates various head sizes.
  • Supple fluid resistant gel pads provide comfort and reduce the incidence of pressure necrosis.
  • No tool required to set and lock horseshoes.

MAYFIELD® Infinity General Purpose Headrest – S419A1050

  • Provides non-invasive cranial support in either supine or semi-sitting procedures.
  • Mini gel pads can be positioned in multiple receptacles and can be tilted on their hinges.
  • Mini gel pads can be used with A1114 MAYFIELD® Infinity skull clamp pin carriers for pinless stabilization.
  • The use of mini gel pads in MAYFIELD® skull clamp pin carriers must be used in conjunction with a horseshoe headrest thanks to the Infinity Support coupler A1112.


MAYFIELD® Infinity Skull Clamp – A1114

  • Multiple, quick-change, snap-in rocker arm options provide the ability to match the stabilization points to the size of the patient’s head for optimal fixation and surgical access.
  • Multiple rocker arm options: Adult, Pediatric and single pin accessory.
  • Two torque screw options 80lb (36kg) & 18lb (8kg) to assist in providing the desired amount of pressure for the patient and the procedure.
  • Always use 18lb torque screw in combination with an horseshoe headrest support.
  • No tools are needed to change rocker arms. 



The MAYFIELD® Infinity Support System (A1112) is a headrest support device that attaches to any MAYFIELD® Base Unit Support Rods (A3101, A2101 or older models), creating a method for simultaneous application of a Headrest (adult, pediatric, or general purpose) and a Skull Clamp (ages 5+).
The MAYFIELD® Infinity Skull Clamp (A1114) is placed on the patient’s skull to hold their head and neck in a particular position when rigid fixation is desired. The skull clamp is indicated for use in open and percutaneous craniotomies as well as spinal surgery when rigid fixation is necessary. The accessories provided with the skull clamp also allow it to be used where stabilization is desired instead of complete fixation.


Do not use for other indications than the ones specified in the Instruction manual.
