In Conclusion

I am reporting this technique as a preliminary pilot project. There has not been a prospective controlled trial evaluating this technique. Further investigation and clinical follow-up is ongoing and I will report on this as new information becomes available.

Later this week, we'll be posting a follow-up blog from Molly Judge, DPM, FACFAS. Dr. Judge will expound upon the suture and button technique for plantar plate stabilization and share some questions on the technique from colleagues at a recent seminar.

Is there results from the seminar yet?

I liked the direct approach your procedure takes to this pathology. My question is how the suture affects the extensor digitorum longus (EDL). Does the tension of the suture cause damage to the tendon? How do you get motion in the joint postoperatively with the tendon tied down with the suture?

The underlying biomechanical cause of many cases of 2nd MTP joint dysfunction is first ray inadequacy. Most patients in the earlier stages of 2nd MTP joint dysfunction can be treated with orthotics, not surgery. Hypermobile first ray, forefoot supinatus can be treated via a first metatarsal head cut out, forefoot valgus posting when appropriate and a metatarsal elevation in the device.

Yes, orthotics are often not covered by insurance and surgery is.

Dr. Davis,

I appreciate your input regarding 2nd MTPJ dysfunction. I agree with you wholeheartedly regarding the potential success of treating HAV with the benefit of orthotic devices. However, the 2nd MTPJ dysfunction has not responded equally well to that therapy. Once the instability has progressed and subtle subluxation and pain has developed, the need for an external splint and accommodative support of the MTPJ predictably provides pain reduction and stability to the affected joint. In my experience, stabilizing the 2nd MTPJ via metatarsal sling pad is far and away the best way to approach this lesser MTPJ instability and pain. The ADDED benefit of a formal orthotic device is an important one but doe not preclude the use of the metatarsal sling pad.

You make a valid point regarding the benefit of orthotic devices in the face of hallux abducto valgus and I agree with you that long-term management includes providing forefoot balancing. In my opinion, treating 2nd MTPJ dysfunction is a conservative issue by and large.

Unfortunately when patients are misdiagnosed, they often present to my office LATER having undergone numerous forms of treatment failures that include surgery. In my article, I emphasize the importance of the clinical and radiographic examination, and the need to exhaust conservative therapy. Only a few patients in my practice have ever required surgical intervention for this condition and I share that experience with the readers. The cases that I discuss in the cover story article on 2nd MTPJ dysfunction are the exception to the rule. In fact, the conservative method is very effective for 2nd MTPJ dysfunction in many cases.

Best regards,
Molly S. Judge, DPM
