Arthroscopic fusion of the ankle and subtalar joint.

This article discusses periarticular fusions of the talus, specifically arthroscopic ankle and subtalar fusions. In addition to principles and techniques of arthroscopic fusion, postoperative care is discussed.

Arthroscopic treatment of intraarticular fractures of the ankle.

In the past, intraarticular fractures that were unresponsive to conservative care have required open arthrotomy. However, recent advances in technology and instrumentation have made arthroscopy of the small joints possible. This article provides an overview of new methods of diagnosis and treatment of intraarticular fractures of the ankle.

The secondary tendinous slip of the extensor hallucis longus (extensor ossis metatarsi hallucis).

In 80% of a random sample the extensor ossis metatarsi hallucis was present. In 90% of these occurrences it arose off the medial aspect of the extensor hallucis longus tendon and coursed distally, medially, and inferiorly an average of 4.0 cm., inserting into the sling portion of the extensor apparatus. Variation of this insertion occurred in 10% of the cases in which the sling portion of the extensor apparatus continued to illustrate fibers of the extensor ossis metatarsi hallucis inserting into it. There is little variation in the occurrence of this tendon between the sexes. The frequency of occurrence of the extensor ossis metatarsi hallucis from this study supports a theory that this tendon should be considered to occur as a rule rather than an exception, and because the previously suggested name of extensor hallucis capsularis is not biomechanically sound, perhaps the tendon merely be termed the secondary extensor hallucis longus.

Endoscopic plantar fasciotomy: a retrospective analysis of results in 53 patients.

This retrospective study analyzes satisfaction of patients who had undergone an isolated endoscopic plantar fasciotomy (EPF) between January 1994 and January 1997. A subjective survey was completed and returned by 53 patients (a total of 69 feet), and a chart review was performed to determine final outcome. Postoperative follow-up averaged 7.2 months (range, 4-42 months). Postoperative pain levels were scored on a 7-point scale at 1 week, 1 month, and 6 months. Forty-three patients (81.1%) were satisfied with the EPF procedure and 10 patients (18.9%) were unsatisfied.

Sliding oblique osteotomy for the treatment of hallux abducto valgus associated with functional hallux limitus.

This is a retrospective study of 27 patients (35 feet) with hallux abducto valgus associated with hallux limitus who underwent a sliding oblique osteotomy for surgical treatment between August 1997 and June 1998. Radiographic analysis and range-of-motion measurements were evaluated with an average follow-up of 65 days (range, 26-100). Preoperative criteria included < 45 degrees of dorsiflexion of the first metatarsophalangeal joint with weightbearing, no evidence of degenerative joint disease at the first metatarsocuneiform joint, and no previous surgical procedures on the first ray. The average preoperative intermetatarsal angle was 9 degrees, hallux abductus angle 17 degrees, and first metatarsal declination angle 15 degrees. The average postoperative intermetatarsal angle was 6.6 degrees, hallux abductus angle 10.3 degrees, and first metatarsal declination angle 21.7 degrees. Eighteen patients (22 feet) had a follow-up of over 6 weeks, and the first metatarsophalangeal joint was evaluated. The average gain in postoperative range of motion with weightbearing was 22.3 degrees.

Arthroscopic evaluation of traumatic injuries to the ankle and foot. Part II: Chronic posttraumatic pain.

Arthroscopic evaluation of major injuries to the lower extremities is receiving more attention in medicine, as techniques become increasingly sophisticated. The following discussion serves as the second of a two-part series reviewing this interesting topic. Part I appeared in the November-December, 1989, issue of The Journal of Foot Surgery, and evaluated acute injuries of the foot and ankle. Part II concentrates on management and recognition of chronic posttraumatic pain.

Ankle arthroscopy in the adolescent patient.

The author reviews 15 cases of ankle arthroscopy in adolescent patients. Most of the patients were female. He discusses the various pathologies identified, with the most common being a medial impingement lesion. Synovitis was present in all cases of persistent discomfort.

Arthroscopic evaluation of traumatic injuries to the ankle and foot. Part I: Acute injuries.

Traumatic osseous and soft tissue injuries of the ankle have enjoyed significant attention in the world literature. Technologic advances over the past 3 decades have allowed investigators to develop parallel methods of treatment of surgical approaches to fractures and soft tissue injuries of diarthrodial joints. The result is the art, science, and technology of arthroscopic surgery.

Techniques of ankle arthroscopy.

Although arthroscopic instrumentation varies widely, the technique for use is quite similar. Surgeon preferences vary but most arthroscopists agree that it is technique that makes the procedure. Discussed in this presentation is the author's method for preparing the patient for arthroscopic surgery, as well as techniques for using the arthroscope, hand instruments, and power instrumentation.

Review of diagnostic arthroscopy of the foot and ankle.

This paper reviews 79 cases of diagnostic ankle arthroscopy. Primary diagnoses and the effects of arthroscopy in relieving the preoperative symptoms are evaluated. In addition to the ankle, arthroscopy of the subtalar and first metatarsophalangeal joints is discussed.
