Correction of Crossover Toe Deformity by Arthroscopically Assisted Plantar Plate Tenodesis

Claw Toe With Dislocated Second Metatarsophalangeal Joint: Treated by Plantar Plate Tenodesis and Release of Collateral Ligaments

Claw toe deformity of the second toe is a common forefoot deformity faced by foot and ankle surgeons. Frequently, it develops as the result of plantar plate insufficiency and subsequent metatarsophalangeal (MTP) joint instability. As the disease deteriorates, the MTP joint can be dislocated. Reduction of the MTP joint without metatarsal osteotomy seems to be a logical approach unless there is excessively long second metatarsal. However, adequate periarticular soft-tissue release including the dorsal capsule, collateral ligaments and extensor tendon is needed to reduce the intra-articular pressure and minimize the risk of joint degeneration. The purpose of this Technical Note is to describe the details of plantar plate tenodesis and release of collateral ligaments for correction of claw second toe associated with dislocation of the metatarsophalangeal joint.

Correction of Severe Crossover Toe Deformity By Plantar Plate Tenodesis, Arthroscopic Release of Lumbrical and Plication of Lateral Capsuloligamentous Complex

Plantar plate deficiency is the major cause of instability of the metatarsophalangeal joint, and plantar plate tenodesis can provide dynamic stabilization of the plantar plate. In case of crossover toe deformity, incorporation of arthroscopic release of the medial capsuloligamentous complex and the lumbrical tendon can eliminate the medial deforming force. However, in case of severe deformity, the lateral capsuloligamentous complex is attenuated. The purpose of this Technical Note is to incorporate the technique of arthroscopic plication of the lateral capsuloligamentous complex into the technique of plantar plate tenodesis and arthroscopic release of the medial capsuloligamentous complex and the lumbrical tendon.

Correction of Crossover Toe Deformity by Plantar Plate Tenodesis and Arthroscopic Release of Lumbrical

Plantar plate deficiency is the major cause of instability of the metatarsophalangeal joint. As the joint subluxates dorsally, the lumbrical is tethered on the medial side of the joint by the deep metatarsal ligament and becomes a deforming force for the development of crossover toe deformity. Release of the lumbrical is needed to achieve adequate medial soft-tissue release. Plantar plate tenodesis has been described to correct the deformity by suturing the plantar plate to the extensor digitorum longus tendon. The purpose of this Technical Note is to incorporate the technique of arthroscopic release of the lumbrical tendon into the technique of plantar plate tenodesis.

Extraction of the Proximal Phalanx: A New Option in Surgical Treatment of the Crossover Second Toe

One of the biggest and commonest problems that is seen and treated by foot and ankle surgeons is the deformity where the second toe crosses over the hallux. According to available literature, this is the first published case of extraction of the proximal phalanx due to crossover toe deformity. We present the case of a 64-year-old Caucasian female with a crossover second toe deformity of her left foot. Because of this deformity, she was completely disabled to wear normal shoes and she felt intensive pain in her front part of the foot. She underwent a total extraction of the proximal phalanx of the second toe. After the operation, she was very satisfied with the status of the operated foot and the final result of the surgical treatment. The procedure that we performed could be a good possibility for the treatment of crossover second toe deformity because we got a good functional and cosmetic result, the morbidity associated with more advanced reconstruction is avoided, and the rehabilitation period was short. Patient satisfaction was high, and complications were minimal.
