Morbidity Associated With Distal Tibial Autograft Harvest.

Distal tibial autograft harvesting has been studied in the past, but morbidity at the level of the donor site is unclear. The purpose of this retrospective review is to assess morbidity in distal tibial autograft harvesting associated with foot and ankle arthrodesis procedures. A retrospective analysis was performed utilizing patients treated in the last 13 years at a large, multicenter, academic, tertiary referral, research institution. Included patients were between the ages of 18 and 80 years old. One-hundred and seven patients (39 male; 68 female) underwent ipsilateral distal tibial bone graft (n = 110) harvesting to augment the index procedure. Patients were followed for an average of 11.2 months after surgery (Range: 1-73 months). The incidence rate of distal tibial stress fractures was 4.5%, with an overall postoperative complication rate of 8.2%. Overall, low complication rates associated with distal tibial autograft harvesting were found, supporting the use of the distal tibia as an appropriate site for autograft harvesting in foot and ankle surgery.

Single and Double Osteotomies of the Calcaneus for the Treatment of Posterior Tibial Tendon Dysfunction.

Posterior tibial tendon disfunction is one of the most commonly treated foot and ankle entities. Surgical treatment may consist of various components and is often performed on an a-la-carte basis. Commonly, joint preservative surgery for posterior tibial tendon dysfunction invariably involves one or more osteotomies of the calcaneus. This article evaluates the current existing evidence guiding providers in the selection of single or double calcaneal osteotomies.

Reoperation, reamputation, and new ulceration following complete or partial toe amputation among diabetic and non-diabetic patients.

AIMS: To compare the number of reoperations, reamputations, and new ulcers following toe amputation in diabetic and non-diabetic patients with sub-group analysis on index amputation level. METHODS: One-hundred sixteen patients with a complete (CTA) or partial (PTA) toe amputation and minimum of 12-month (12 M) follow-up were identified in electronic medical records. The number of reoperations and reamputations, number and location of new ulcers, and final amputation level of the ipsilateral extremity were compared between diabetic and non-diabetic patients and between those with CTA and PTA at 12 M and final follow-up (FFU). RESULTS: Diabetic patients had significantly more reoperations, reamputations, and new ulcers than non-diabetic patients at 12 M and FFU. There were no differences in reoperations, reamputations, or new ulcer location between CTA and PTA; however, patients with PTA developed more new ulcers at 12 M and FFU and were more likely to have a distal final amputation level compared to those with CTA. CONCLUSIONS: Diabetic patients required significantly more reoperations and reamputations following a toe amputation and developed more new ulcers than non-diabetic patients regardless of index amputation level. These high rates among diabetic patients highlight the complications encountered following toe amputation and emphasize the need for close, multi-disciplinary care.

Common Pitfalls in Subtalar Joint Preparation for Arthrodesis via Sinus Tarsi Approach.

This cadaveric study assessed factors that could lead to nonunions in subtalar joint arthrodesis. The purpose of this study was to assist surgeons in achieving sufficient joint preparation in hopes to achieve more frequent arthrodesis of the subtalar joint. We evaluated the influence of experience in regard to cartilage preparation of the joint. We also assessed which quadrants of the subtalar joint were more likely to have unprepared cartilage. The subtalar joints in 17 cadaveric limbs were prepared by 17 participants with differing levels of experience. After the cartilage was denuded, the percentage of unprepared cartilage in each subtalar joint was calculated. The medial quadrants were more likely to have unprepared surfaces. There was also a learning curve present with subtalar joint preparation, as seen by the significantly larger percentage of unprepared cartilage in cadavers prepared by first year residents.

Special Considerations in the Management of Diabetic Ankle Fractures.

PURPOSE OF REVIEW: Ankle fractures and diabetes mellitus are both increasing in prevalence. Patients with both diabetes and an ankle fracture have been shown to have an increased rate of complications which can be catastrophic. The purposes of this review are to identify factors placing patients at an increased risk and offer guidance on the management of these injuries, in order to reduce potential complications. RECENT FINDINGS: Non-operative management of unstable ankle fractures in patients with diabetes results in an unacceptably high rate of complications. Operatively managed patients with uncomplicated diabetes seem to fair as well as patients without diabetes. Thus, it is important to recognize patients as either complicated or uncomplicated at the onset of their treatment based on comorbidities. There is limited evidence to guide the management of ankle fractures in patients with diabetes, in particular those deemed complicated. Non-operative management of unstable fractures in diabetic patients should be avoided.

Multiplanar Correction of the Lesser Digital Deviation and Indirect Plantar Plate Rupture Repair Using a Braided Polyethylene Nylon Suture: A Technique Guide.

Forefoot and lesser digital pathology continues to be a challenging area of surgical correction for foot and ankle surgeons. Many techniques for the correction of digital deformities secondary to plantar plate rupture, regardless of planal dominance, have been described including direct repair and metatarsal shortening osteotomies for repair. The authors present a new technique for multiplanar correction of deformed lesser digits without direct repair of the plantar plate rupture utilizing a specialty suture. The technique utilizes a braided synthetic polyethylene Nylon suture, which has been traditionally used for open or arthroscopic shoulder labrum repair, for the stabilization of the lesser metatarsophalangeal joint. This novel technique guide for the correction of transverse and sagittal plane deformities of the digit at the metatarsophalangeal joint negates the need for a plantar incisional approach for plantar plate repair or metatarsal head osteotomy from a dorsal approach with augmented stabilization.

Subtalar Distraction Arthrodesis with Fresh Frozen Femoral Neck Allograft: A Retrospective Case Series.

UNLABELLED: Subtalar joint distraction arthrodesis has been well reported with use of structural iliac crest or local autologous bone graft for malunited calcaneal fractures. Early reports for structural allograft did not yield good, consistent results, leading to a subsequent lack of recommendation in previous literature. Newer studies have had promising results utilizing femoral allograft as an alternative to autogenous bone graft. We performed a retrospective chart review on 10 patients (12 feet) undergoing subtalar joint distraction arthrodesis with femoral neck allograft for malunited calcaneal fractures. The primary aim of this study was to report on successful union rates and, in addition, outline any consistent complications. Twelve of the 12 procedures (100%) yielded successful fusion with a mean final follow-up of 7.7 months (range = 2.2-35.1 months). The mean increase in talocalcaneal height was 4 mm (range = 2-6 mm). The overall complication rate was 16.6%, including one superficial wound complication that healed uneventfully and one hardware removal. In conclusion, the current study reports a 100% successful fusion rate with interpositional structural femoral neck allograft in treatment for malunited calcaneal fractures. LEVELS OF EVIDENCE: Therapeutic, Level IV: Case series.

Soft tissue fixation with a cortical button and interference screw: a novel technique in foot and ankle surgery.

Tendon transfers are commonly performed procedures in the foot and ankle. They have been described for multiple tendons and a myriad of pathologies. One issue with these procedures has always been inadequate fixation with several methods available to the surgeon. In this report, we describe a novel technique in foot and ankle surgery using a cortical button and an interference screw.
