Triple Arthrodesis: A Long-term Study with Force Plate Analysis This study evaluated triple arthrodesis at late follow-up using the liquid crystal force plate and standard clinical methods. Twenty-four patients with 36 triple arthrodeses were followed-up at an average of 8 ± 2 years. Fifty-eight per cent of patients achieved an ideal or good rating with 11% failures. Failures were due to inadequate surgical correction of varus deformity. Seven per cent of joints with roentgenographic degenerative changes had associated mild pain. Triple arthrodesis produced many deviations from normal load-bearing: 1) calcaneovalgus residuals produced symptomatic posterior heel force concentrations; 2) residual forefoot supination produced symptomatic force concentrations under the fifth metatarsal and toe; 3) residual forefoot pronation produced increased midfoot and medial metatarsal load-bearing, generally asymptomatic; and 3) a significant increase in midfoot weightbearing occurred in most triple arthrodesis patients.

Unrecognized Laceration of Tibialis Anterior Tendon: A Case Report Surgical exploration of the traumatic wound is always important to allow full definition of the extent of injury. The authors report a case of a lacerated tibialis anterior tendon that was initially overlooked 8 years prior to presentation.

Anatomical Considerations of Posterior Tibialis Tendon Entrapment in Irreducible Lateral Subtalar Dislocation Irreducible lateral subtalar dislocation is associated with posterior tibialis tendon entrapment. Mulroy 7 and Leitner 6 have proposed conflicting theories regarding the exact mechanism of tendon entrapment. Cadaveric analysis of lateral subtalar dislocation supported Leitner's 5 contention that tearing of the flexor retinaculum promotes posterior tibialis tendon entrapment. Retinacular disruption allowed tendon subluxation over the medial malleolus and talar head to the entrapped position. Entrapment of the flexor digitorum longus only occurred in the Leitner model. When the flexor retinaculum and deep posterior compartment fascia were preserved, the muscle failed at the musculotendinous junction. Flexor hallucis longus entrapment could not be produced in either experimental model. Plantarflexion of the great and lesser toes, noted on clinical presentation, is caused by functional lengthening of the route coursed by the flexor digitorum longus and flexor hallucis longus.

Foot Pressure Studies in the Assessment of Forefoot Arthroplasty in the Rheumatoid Foot To assess the results of forefoot arthroplasty, dynamic and static foot pressure studies have been made of the rheumatoid foot in both a prospective study group of 60 feet and in a retrospective study group of 18 feet. Significant reductions of pressure in the forefoot were found. Problems associated with the first and fifth metatarsals were considered.

The Measurement of Pressures under the Foot An apparatus is described which gives a rapid and detailed picture of the distribution of pressure under the foot, this being displayed either as a continuous grey scale or a color contour map on a television monitor. Automatic analysis systems are outlined which enable the quantitation of the distribution of pressures and loads under the foot during standing and walking, utilizing computer techniques. The use of the static system is illustrated by the results of analytic procedures carried out on normal feet and in the assessment of surgical correction of a series of equino-varus feet in children suffering from spina bifida. The clinical application of the dynamic system is illustrated by the measurement of pressure/time curves encountered under the heel, the five metatarsal heads, and the great toe of a control group of feet and the feet of patients who had undergone metatarsophalangeal fusions, Keller arthroplasties, and Swanson arthroplasties.

The Arterial Anatomy of the Talus The extraosseous and intraosseous vascularity of the talus was studied in 26 fresh cadaver limbs. The specimens were injected with latex or Batson's compound, debrided by a nondissection technique, and cleared by a modified Spalteholz method. The extraosseous vascularity was through the branches of the three major regional arteries which entered the five nonarticulating surfaces of the bone. The major blood supply to the body was provided by the artery of the tarsal canal. The deltoid and sinus tarsi vessels provided significant minor sources of vascularity. The superior neck and posterior tubercle vessels supplied small areas of the body, but did have anastomoses with the other arteries in some specimens. These vascular patterns correlated well with the reported incidence of avascular necrosis of the body of the talus following injury.

Arthroscopy of the Posterior Subtalar Joint: A Preliminary Report The technique of arthroscopy is, at the present time, available for the investigation of the subtalar joint. In this preliminary report, the relevant anatomy and technique are reviewed. Illustrative cases are presented to review some of its applications. It is the conclusion of the author that arthroscopy of the subtalar joint may be of value in the following situations: (1) assessment of the articular cartilage in suspected cases of degenerative, rheumatoid, or infectious arthritis; (2) evaluation of chronic pain syndrome in the hindfoot after injuries; and (3) biopsy of the synovial lining, breakage of adhesions, joint lavage, and removal of loose bodies.

Stenosing Tenosynovitis of the Flexor Hallucis Longus Tendon and Posterior Impingement upon the Os Trigonum in Ballet Dancers The problems of flexor hallucis tendonitis and os trigonum syndrome in dancers are presented. The mechanism of injury, diagnosis, treatment, and rehabilitation are outlined. Pitfalls in diagnosis are discussed as well as prognosis for return to dance class and the stage. The best surgical access to the os trigonum is a lateral approach.

High Pressure Water Injection Injuries of the Foot: A Report of Two Cases Few cases of high pressure water injection injuries of the foot have been reported. These cases suggest that only minimal soft tissue destruction results and that, with con servative or limited surgical management, full recovery should be expected. 1 , 9 This is a report of two cases of this “benign variant” of high pressure water injection injury that resulted in toe amputations.

<i>Acinetobacter calcoaceticus</i>Foot Infection Secondary to High-pressure Injection Injury: A Case Report Injection injuries are surgical emergencies occurring most often in the hand and frequently associated with widespread tissue necrosis and infection. This report presents a case of high-pressure injection injury of the foot associated with extensor hallucis longus laceration and infection with Acinetobacter calcoaceticus variant anitratus. This injury occurred with a high-pressure “water-blaster” tool used to remove paint from pavement. Similar injuries in the foot have not been reported. A. calcoaceticus is a widely distributed normal flora of low virulence, often waterborne, which is rarely found in orthopaedic infections in young healthy patients. Clinical features of high-pressure injection injuries, principles of treatment, and the characteristics of A. calcoaceticus are reviewed.
