Anesthesia blocks of the lower extremity. Comparing the Biojector with needle and syringe.

Podiatric surgical procedures frequently involve administration of preoperative local anesthesia, and because of the nature of these blocks, it is believed that needle-free injection could greatly enhance this aspect of clinical practice. The object of the study was to determine if needle-free injections with the Biojector were equivalent to needle and syringe injections for ankle, Mayo, neuroma, hallux, and digital anesthetic blocks. The results indicate that needle-free injection with the Biojector is equal to needle and syringe for some anesthesia blocks. More research in this area is needed to determine if technique with the Biojector has an impact on time of anesthesia onset or on level of discomfort and ecchymosis.

Clinical experience with two-component first metatarsal phalangeal joint implants.

The development of the two-component implant systems has generated considerable interest over the past 5 years. It is important to critically document and record the clinical experiences with these devices as they occur. The authors present an objective evaluation of their early findings and comment on possible recommendations for the future.

Effects of surgical technique on bone. A preliminary study.

The authors compared the use of the power saw with bone-cutting forceps for excision of bone. A total of 44 digits were studied in 12 patients. The study was performed on patients requiring bilateral digital arthroplasties of the proximal and distal interphalangeal joints. The authors examined the differences in healing: pain, inflammation, and fibrosis. Digits on which the power cuts were made showed a slight advantage with regard to inflammation and pain, until 1 week after surgery. By week 12, neither technique demonstrated superiority. Overall results demonstrated no significant digit (p > 0.2) or treatment effect (p = 0.11). The authors believe that the study showed that the technique used for bone excision may have little effect on inflammation and healing in the long-term management of a surgical patient.

Effectiveness of absorbable fixation devices in Austin bunionectomies.

Forty-eight Austin bunionectomies were fixated by using an absorbable fixation device. Twenty-three were fixated with a 1.5- or 2.0-mm diameter Biofix rod and twenty-five were fixated with a 1.3-mm diameter Orthosorb pin. To be included in this project, all patients were followed radiographically for a minimum of 3 months. One foot (4%) fixated with Biofix developed a sterile sinus discharge 3 months postoperatively after uneventful wound healing. There were no clinical or radiographic changes seen in the feet in which Orthosorb was used. Also, there were no infections or osteotomy dislocations with either fixation device.

Digital arthrodesis.

Digital arthrodesis is a common surgical procedure but requires selection of the proper procedure and fixation device to achieve the desired result. This article presents the various methods which have been found effective in achieving an arthrodesis of the hallux and/or lesser toes. The various procedures and fixation devices are described in detail along with their advantages and disadvantages.

Digital implantation.

The digital implant is an excellent alternative to arthroplasty or fusion procedures, provided that all preoperative criteria are met. It appears to yield the best result with the fewest complications when inserted in a second or third toe at the proximal interphalangeal joint in a rectus foot type.

Swanson design finger joint implant utilized in the proximal interphalangeal joints of the foot: a preliminary study.

The purpose of this paper is to present preliminary findings regarding the use of the Silastic finger joint implant H.P. (Swanson design) in resection arthroplastic procedures of the proximal interphalangeal joint of the second and/or third toes. This paper reports on 42 cases which have beer, performed and in which significantly satisfactory results have been achieved.

Complications of the Austin-type bunionectomy.

The California College of Podiatric Medicine has evaluated the complications encountered in the Austin-type bunionectomy and compiled the following list of possible causes: 1) improper preoperative criteria, 2) incorrect angle between arms of the V-osteotomy, 3) incorrect direction of the osteotomy on the transverse plane, 4) removal of too little or too much bone medially in a bi-correctional procedure, 5) transposition of capital fragment too far laterally, 6) failure to remove medial wedge at least 80% through the head, 7) placement of V-osteotomy in cystic or osteoporotic bone, and 8) improper instrumentation. Dr. Gerbert believes that the use of templates preoperatively will minimize the number of complications.
