- Overlapping Toes:
- involves an dorsal-adduction deformity of the 5th toe;
- other components of the deformity include external rotation of the digit, contracture of the EDL tendon;
- in some cases there may be dislocation of the MTP joint;
- often the deformity is familial and bilateral;
- clinical findings:
- the deformity is asymptomatic, but it can cause difficulty with shoe wear and pain over the dorsum of the toe;
- a dorsal callus is commonl;
- in some cases, there will be an associated bunionette;
- DuVries Correction:
- may use lateral incision from osteotomy or may make second incision in 4th interspace;
- release the EDL, dorsal joint capsule, and medial collateral ligament;
- Butler's Surgical Correction:
- create a dorsal racket incision over the little digit, centered over the EDL tendon;
- this allow the toe to be derotated;
- a second "handle" incision is made on the plantar aspect of the original wound, which is brought laterally and proximally;
- this incision allows the toe can now be moved laterally and plantarly;
- release the contracted extensor tendon and the dorsal capsule;
- in some cases, the plantar capsule will have to be released through the dorsal capsule;
- for a good surgical result, the toe must passively lie in a corrected position;
- forced correction may place tension on the digital vessels;
- if residual deformity is present, more capsule needs to be excised;
- skin sutures can help keep the toe in a derotated position;
- in the report by Thordarson, et al, the auhtors report on 3 patients treated with a simpler procedure involving metatarsal phalangeal capsular release dorsally and medially, oblique lengthening of the extensor tendon, and Z-plasty of the skin;
- ref: Congenital crossover fifth toe correction with soft tissue release and cutaneous Z-plasty.
- Curly Toes:
- involves malrotation of one or more toes along w/ digit flexion deformity;
- in contrast, hammer toes are generally not mal-rotated;
- may be due to contracture of FDL and FDB;
- common disorder in children
- look for symmetric deformity in the opposite foot;
- involves FDL tenotomy at age 3-4 years;
- with more severe deformity consider Girdlestone Taylor Procedure
