Soft Tissue Procedures
Osseous Procedures
Sequential Release
15
• Tenotomy
• Extensor tenotomy and capsulotomy
• Flexor tenotomy and capsulotomy
• Flexor tendon transfer

Resection of base

Syndactylization
Arthroplasty
Arthrodesis

Most common procedure performed for
hammertoe correction
May or may not require fixation
Usually requires addition of soft tissue procedures
19
Types of fixation
K-wire
Absorbable rod
Implants
Shaw rod
Ship implant
20
Usually requires addition of soft tissue procedures
Is not performed on the fifth digit
Requires fixation
Types of fixation
K-wires (smooth or threaded)
Screws
Various implants
21
End to End
Peg in hole
Insitu
22
Arthroplasty
Most common procedure performed for
hammertoe correction
Technically easy procedure
Some motion is retained
Shortening of digit is inherent to
procedure
May be unstable
Increased chance of recurrence of
hammertoe deformity
Fixation
K-wire
Implant
Indications
Flexible to semi – rigid deformity
Athrodesis
Not as common
Technically more difficult procedure
No motion, toe is rigid
Maintains relative length of digit
Stable
Minimal chance of recurrence
Longevity of correction
Fixation
Screw
Threaded or Smooth K-wire
Implant
Indications:
Loss of Intrinsic muscle stability
Diabetes
Neuromuscular conditions
23
Technically easy
No exposed K-wire
Less chance of pin tract infection
No need to remove the pin at a later date
Less chance of bending or breaking of the pin
Quicker return to bathing and shoe gear
Provides superior compression
Provides stability even in the face of pseudoarthrosis
Stabilizes both distal and proximal interphalangeal joints

Don’t try to be an expert on procedure choice
Be the expert on your implant
Know the technical aspects of your implant
(i.e. lengths, diameter, etc.)
