Repair of Neglected Achilles Rupture.

Acute Achilles tendon ruptures is routinely missed or undertreated, leading to functional deficits. The neglected Achilles ruptures often requires surgical repair to regain functional improvement. The tendon retraction and resultant necessary debridement of the rupture site leads to difficulty completing end-to-end repair.

A Multicenter, Retrospective Study of Early Weightbearing for Modified Lapidus Arthrodesis.

The modified Lapidus arthrodesis is a long-established surgical technique for management of hallux valgus that provides reproducible results and quality patient outcomes. The data from 367 consecutive patients undergoing unilateral modified Lapidus arthrodesis from January 1, 2007 to December 31, 2008 at participating centers were retrospectively evaluated. The included patients were categorized into early weightbearing (≤ 21 days) and delayed weightbearing (> 21 days) groups.

Injury to the Posterior Tibial Tendon After Open Reduction Internal Fixation of the Medial Malleolus.

Unlabelled: The management of ankle fractures with open reduction and internal fixation (ORIF) has been a proven method to help prevent deformity and posttraumatic arthritis. The incidence of continued ankle pain due to retained hardware after ORIF of ankle fractures has been documented. The goal of this study was to determine if the starting point for medial malleolus screw placement is associated with posterior tibial tendon (PTT) damage when performing ORIF of the medial malleolus.

The fifth metatarsal base: anatomic evaluation regarding fracture mechanism and treatment algorithms.

Fractures occurring within the 1.5-cm proximal portion of the fifth metatarsal are commonly considered avulsion fractures. The exact mechanisms of such fractures are controversial.

Screw placement relative to the calcaneal fracture constant fragment: an anatomic study.

Placement of a screw from the lateral wall of the calcaneus into the constant sustentaculum tali fragment can be difficult when surgically repairing a calcaneal fracture. This screw serves to compress the fracture fragments and support the posterior facet. This difficulty results from the small landing zone of the sustentaculum tali with its nearby vulnerable soft tissue structures.

Structures at risk with medial double hindfoot fusion: a cadaveric study.

Although discussed as an alternative to triple arthrodesis for hindfoot correction, the published data surrounding the medial double arthrodesis, or fusion of the subtalar and talonavicular joints, has not addressed the proximity of the anatomic structures at risk. A total of 10 cadaver specimens were used to examine the risk of damage to the neurovascular and tendinous structures of the posterior medial hindfoot when performing the medial double arthrodesis. The distance of the reviewed structures was measured in relation to the standardized point of the middle facet of the calcaneus (mean ± standard deviation and range).

Retrograde Intramedullary Nail With Femoral Head Allograft for Large Deficit Tibiotalocalcaneal Arthrodesis.

Background: Large bone defects present a difficult task for surgeons when performing single-stage, complex combined hindfoot and ankle reconstruction. There exist little data in a case series format to evaluate the use of frozen femoral head allograft during tibiotalocalcaneal arthrodesis in various populations in the literature.

Methods: The authors evaluated 25 patients from 2003 to 2011 who required a femoral head allograft and an intramedullary nail.

A retrospective comparison of cost and efficiency of the medial double and dual incision triple arthrodeses.

While the medial double arthrodesis has gained significant popularity for hindfoot arthrodesis in recent years, much has been touted about the efficiency and cost savings of the procedure in comparison to its triple counterpart without any literature to reinforce this claim. The purpose of this retrospective study was to compare the hardware costs and operative time between the medial double and triple arthrodeses. A total of 276 patients (277 feet) were identified via CPT codes with 47 hindfoot cases (47 feet) meeting the inclusion criteria consisting of 21 medial double (6 males, 15 females) and 26 triple (8 males, 18 females) arthrodeses.

Ankle valgus after hindfoot arthrodesis: a radiographic and chart comparison of the medial double and triple arthrodeses.

The medial double arthrodesis, comprised of subtalar and talonavicular joint fusions, has become a popular way to correct hindfoot deformity. There is potential concern for an increase in ankle valgus postoperatively owing to extended medial dissection and possible disruption of the deltoid ligament. Although this approach is often used to correct a valgus hindfoot, little attention has been paid to date on this procedure's effect on the tibiotalar joint.

Quantitative assessment of the yield of osteoblastic connective tissue progenitors in bone marrow aspirate from the iliac crest, tibia, and calcaneus.

Background: It is well known that bone marrow aspirate from the iliac crest contains osteoblastic connective tissue progenitor cells. Alternative harvest sites in foot and ankle surgery include the distal aspect of the tibia and the calcaneus. To our knowledge, no previous studies have characterized the quality of bone marrow aspirate obtained from these alternative sites and compared the results with those of aspirate from the iliac crest.

Intermediate-term results following first metatarsal cheilectomy.

Hallux rigidus is a term describing degenerative joint disease (DJD) to the first metatarsal phalangeal joint (MTPJ). It is the most common DJD encountered in the foot and is the second most common pathology of the great toe behind hallux valgus. The goal of a cheilectomy is to relieve pain and increase MTPJ motion.

Evans osteotomy and risk to subtalar joint articular facets and sustentaculum tali: a cadaver study.

The Evans lateral column lengthening procedure allows correction of abduction, improved talar head coverage, decreased forefoot and rearfoot valgus, and improvement of medial column arch height. However, identifying the structures at risk when performing this osteotomy has proved difficult in vivo. Using 10 cadaveric lower limbs, we performed the Evans calcaneal osteotomy and determined whether violation of the calcaneal facets and the sustentaculum tali occurred.

Strength evaluation of lateral calcaneal wall with circular external fixation application in cadaveric specimens.

Circular external fixation is a useful treatment option for the correction of complex trauma, extremity deformity, osteomyelitis, and reconstruction of the foot and ankle. The goal of the present study was to determine the degrees of bolt rotation required to create enough wire tension to cause structural failure of the lateral calcaneal wall when stressed with both olive and smooth wires in a cadaveric model. Ten fresh, thawed, below-the-knee specimens were tested at the San Diego Cadaveric Academic Research Symposium.

Modern techniques in hallux abducto valgus surgery.

Hallux abducto valgus surgery is in a constant state of evolution. Innovation is driven by surgeons pursuing the perfect procedure for any clinical scenario. The end point is to eliminate complications and produce satisfied patients.

Interference screw fixation and short harvest using flexor digitorum longus (FDL) transfer for posterior tibial tendon dysfunction: a technique.

Posterior tibial tendon dysfunction is a common clinical entity treated by foot and ankle specialists, and numerous surgical treatments are available to the modern foot and ankle surgeon. Fixation methods are constantly evolving as new products are developed and new uses for existing products are attempted. Interference screw fixation is the gold standard fixation for tendon autograft and allograft in orthopedic sports medicine.

High-pressure water injection of the foot with associated subcutaneous emphysema: a case report.

A review of the literature yields few reported cases of industrial-strength high-pressure water injection injuries involving the foot, and sources of information for industrial-strength high-pressure water injection injuries reside primarily in the hand surgical literature. Toxic materials, such as grease, paint, and diesel oil, are relatively common agents involved in injection injuries, and these substances are associated with increased morbidity in comparison with injection of water or air. Treatment of high-pressure injection of a toxic substance is a surgical emergency requiring irrigation, debridement, antibiotic administration, and monitoring for signs and symptoms of compartment syndrome.
