When performed correctly the procedure described in conjunction with the SHIP Implant, yields impressive results.
Tools needed: burr with btop, broach, burr without stop, color coded sizers.
Semi-elliptical incisions are made on the second, third, and fourth toes. A straight incision is used on the fifth toe.
The extensor longus tendon is transversely incised proximal to the interphalangeal joint and reflected distally.
An arthroplasty is performed excising 6-8 mm of the proximal phalanx head.
Excise all sharp edges from the phalanx stump. Drill the canals for the stems using the SHIP burr with stop for the small and medium SHIP implant. The broach is used to enlarge and square the pilot hole.
A
color coded sizer is used to determine the final fit of each implant. The stems should fit so that the implant abuts flush against the intermediate phalanx and the proximal phalanx stump. After sizing of the implant the wound is flushed copiously. An antibiotic flush is recommended.
The closing steps are: 1) suture
the tendon, 2) close the subcutaneous tissue, 3) close
the skin. This closes the pocket around the implant
securely, stabilizing the toe. The correction should be
achieved at this time. A Betadine soaked sponge is an
excellent splint for the first two weeks. Wrap each toe
individually with 1 inch Coban starting at two weeks
post-op. Use prophylactic antibiotics on every toe
implant case.
On certain fifth toes there is a need for an
additional osteotomy of the lateral one-fourth of the
intermediate phalanx. This will aid in narrowing
the girth of the toe. This is usually performed
prior to the arthroplasty of the proximal phalanx
head. the arthroplasty is then performed and the
implant can be put in place. There is ample
intermediate phalanx base left to drill a hole for the
distal stem.
