    Title Chronic Disorders of the Achilles Tendon: Results of Conservative and Surgical Treatments.
    Date October 1997
    Journal Foot & Ankle International / American Orthopaedic Foot and Ankle Society [and] Swiss Foot and Ankle Society
    Excerpt

    We reviewed our results of nonoperative and operative treatment of chronic Achilles tenosynovitis to further define outcomes and treatment parameters. Forty-one patients presented with an average of 14 weeks of Achilles tendon symptoms. All patients received nonsurgical treatment initially, and 21 patients (51%) recovered after an average of 18 weeks of therapy. Three additional patients improved after brisement of the tendon/peritenon interspace. Seventeen of 41 patients eventually underwent soft tissue tenolysis and/or excision of degenerative tendon cysts. Those patients who responded to nonoperative therapy tended to be younger (average age, 33 years) than those who had degenerative tendon changes requiring surgery (average age, 48 years). All surgical patients were able to return to unrestricted activity after 31 weeks (range, 27-48 weeks). We believe 4 to 6 months of nonsurgical therapy is appropriate for middle aged patients or athletes with chronic Achilles tenosynovitis. Those that fail this treatment will improve with a limited debridement of diseased tissue without excessive soft tissue dissection of the tendon.

    Title Treatment of Chronic Heel Pain by Surgical Release of the First Branch of the Lateral Plantar Nerve.
    Date July 1992
    Journal Clinical Orthopaedics and Related Research
    Excerpt

    Sixty-nine heels (53 patients) with chronic heel pain had a surgical release of the first branch of the lateral plantar nerve. The average duration of heel-pain symptoms was 23 months (range, six months to eight years). No patient had less than six months of conservative treatment before surgery. The average duration of preoperative conservative treatment was 14 months. Forty-four patients (83%) had taken nonsteroidal antiinflammatory agents. Sixty-three heels (91%) had used heel cups and/or orthoses. Fifty-nine heels (86%) had received one or more injections of a steroid preparation. Thirty-four heels had developed pain initially during a sports activity. Postoperatively, 61 heels (89%) had excellent or good results; 57 heels (83%) had complete resolution of pain. The average follow-up period was 49 months. In general, heel pain resolves with conservative treatment. In recalcitrant cases, however, entrapment of the first branch lateral plantar nerve should be suspected. Surgical release of this nerve can be expected to provide excellent relief of pain and facilitate return to normal activity.

    Title Chronic Heel Pain. Treatment Rationale.
    Date November 1989
    Journal The Orthopedic Clinics of North America
    Excerpt

    Chronic heel pain needs a treatment rationale. Most heel pain responds to conservative treatment. When surgery is done, the surgeon must be aware of the anatomy and especially the nerves about the heel that can cause pain. The author's experience is presented.

    Title The History of Carpal Tunnel Syndrome.
    Date June 1988
    Journal Journal of Hand Surgery (edinburgh, Scotland)
    Excerpt

    Carpal tunnel syndrome is the most frequently diagnosed, best understood and most easily treated entrapment neuropathy. During the first half of the 20th century, however, most patients with carpal tunnel syndrome were diagnosed as having compression of either the brachial plexus or thenar nerve motor branch of the median nerve. As late as 1950, only twelve patients with operative release of the transverse carpal ligament for idiopathic carpal tunnel syndrome had been reported. The delay in accurate anatomical localization of this compressive neuropathy can be attributed both to the confusion caused by the diverse manifestations of median nerve compression in the carpal tunnel, and to some interesting developments that altered early investigations in this area.

    Title Results of Treatment of Severe Carpal-tunnel Syndrome Without Internal Neurolysis of the Median Nerve.
    Date August 1987
    Journal The Journal of Bone and Joint Surgery. American Volume
    Excerpt

    Thirty-three hands (twenty-nine patients) had a release of the carpal tunnel without internal neurolysis for severe carpal-tunnel syndrome. All of the hands had increased values for two-point discrimination or thenar atrophy, or both. Twenty-three (89 per cent) of the twenty-six hands that had increased values for two-point discrimination and twenty-six (87 per cent) of the thirty hands that had an elevated result on Semmes-Weinstein testing had normal values at follow-up. Nine (90 per cent) of the ten hands that had weakness of the thenar muscles (grade-3 strength or less) regained grade-4 or 5 strength. Thirteen (65 per cent) of the twenty hands that had thenar atrophy regained normal muscle bulk. Eighteen (62 per cent) of the twenty-nine patients had complete resolution of symptoms and signs of compression of the median nerve. No significant difference was found between the results in this series of patients and those in a previously reported similar group of patients who were treated by release of the carpal tunnel combined with internal neurolysis of the median nerve.

    Title In Vivo Growth Plate Stimulation in Various Capacitively Coupled Electrical Fields.
    Date November 1984
    Journal Journal of Orthopaedic Research : Official Publication of the Orthopaedic Research Society
    Excerpt

    The right proximal tibial growth plates of adolescent New Zealand white rabbits were stimulated with various capacitively coupled electrical fields. Capacitor plates attached to plastic jigs placed over the proximal tibiae were connected to function generators which supplied sine wave signals of 60 kHz frequency and various voltages (2.5, 5, 10, and 20 V peak-to-peak). At 0 h and at 48 h, each animal was labeled with intravenously injected oxytetracycline. For the next 48 h, each right proximal tibial growth plate was stimulated with one of the above electrical signals. At the end of the 48 h of stimulation, the animals were sacrificed, and the tibiae were excised; histological sections of the proximal growth plate in each tibia were made, and the distance the labels moved away from the bone-cartilage junction down into the metaphysis was measured under fluorescent microscopy. Results indicate that the rabbit growth plate can be consistently stimulated to statistically significant accelerated growth in a capacitively coupled electrical field. A dose-response effect was noted, with 5 V peak-to-peak exhibiting maximum growth acceleration. Thus, the application of the proper capacitively coupled electrical field significantly stimulated the rabbit growth plate at voltage and current levels that are safe for human use.
