Gangrene in the diabetic foot: its implications and consequences.

Diabetic problems of the feet are not uncommon. Occasionally, these difficulties progress to the point where surgical intervention is required. A case was presented which involved a deep abscess of the foot that compromised the circulation to the toe. Ultimately, open toe amputation was necessary. The etiologic factors causing diabetic complications were presented and the importance of each was stressed. The preoperative considerations for surgical amputation and debridement were defined, as well as the possibility for successful healing.

Compression: is it necessary for bone healing?

The authors present a review of bone healing. A literary search on the subject reveals a variety of experiments performed on healing bone using different techniques. The review of this literature establishes that compression in bone healing is not absolutely necessary. It also relates that bone healing without any fixation is not desired. Therefore, the goal of this paper is to enlighten the surgeon that controlled, semirigid, semicompressed fixation with active range of motion is the ideal criteria for bone healing, and decreases the chance of cast disease.

A quantitative method of determining the pneumatic ankle tourniquet setting.

Pneumatic ankle tourniquets are currently used in podiatry for maintaining hemostasis during foot surgery. The literature is limited concerning the safest pressure to use with this device. This study was undertaken to develop a simple and reliable method of deriving a proper pressure setting that would be safe and efficacious. Using a Doppler stethoscope, the minimum effective tourniquet pressure was established on 54 limbs from 35 patients undergoing foot surgery at our institution. The average pressure needed to obtain a "bloodless field" was 218.6 +/- 34.6 mm. Hg. However, in the younger, normotensive patients the average pressure utilized was 203.9 +/- 22.3 mm. Hg. The lower pressures used were felt to be safer and better tolerated by the patients. The authors concluded that the minimum effective pressure should be determined for each patient preoperatively and the routine use of a maximum safe pressure of 250 mm. Hg should be discouraged.

Hallux varus--surgical correction and review of the literature.

Acquired hallux varus may follow correction of hallux abducto valgus by the modified McBride procedure. The authors discuss correction of both acquired and congenital hallux varus and show pre- and postoperative illustrations of both types.
