Some leaders of the profession and its educational components have voiced concern about changes under way in California and questioned whether the state board of podiatric medicine is acting appropriately. The author attempts to clarify the role of state licensing boards, developments in California, and the board's alignment with those calling for state licensing agencies to help lead reform of medical education.
Background: Various techniques may be used to repair Achilles tendon ruptures; however, we contend that using the strongest suture with the least amount of suture material is ideal.
Methods: To compare the strength of 2-0 FiberLoop (Arthrex Inc, Naples, Florida) and #2 Ethibond (Ethicon Inc, Somerville, New Jersey) suture materials in Achilles tendon repairs, 12 Achilles tendons were harvested from cadavers aged 18 to 62 years (median age, 42 years). The tendons were transected and repaired using a modified Krackow suture technique. All of the right limbs were repaired with 2-0 FiberLoop, and the contralateral side was repaired with #2 Ethibond. The specimens were mounted to a materials testing system, and the repairs were pulled to failure in an anatomical direction.
Results: The mean ± SD yield loads of 2-0 FiberLoop and #2 Ethibond were 233 ± 48 N and 134 ± 34 N, respectively (P = .002). The mean ± SD ultimate load of 2-0 FiberLoop was 282 ± 58 N, and that of #2 Ethibond was 135 ± 33 N (P < .001). The cross-sectional area of one pass of 2-0 FiberLoop was calculated to be 0.21 mm2, and one pass of #2 Ethibond was 0.28 mm2.
Conclusions: The smaller-caliber 2-0 FiberLoop was significantly stronger than #2 Ethibond. This study suggests that there is no advantage to using the traditional larger suture material for Achilles tendon repairs; however, further clinical testing is needed to determine the optimal repair technique.

Chronic decubitus ulceration of the heels is a common condition encountered by podiatric physicians, especially in diabetic patients. Very often these ulcerations can progress to osteomyelitis of the calcaneus. Many times, this in turn leads to a below-the-knee amputation. A partial calcanectomy is a viable alternative to below-the-knee amputation. A more functional limb both mechanically and cosmetically is achieved, and the morbidity and mortality associated with the calcanectomy is less than with a below-the-knee amputation. A brief overview of the history and outcomes associated with this procedure is outlined and a case utilizing a partial calcanectomy is presented. (J Am Podiatr Med Assoc 91(7): 369-372, 2001)
Arthrodesis of the Interphalangeal Joint of the Hallux
A Simple and Effective Technique
The authors present a simple and effective technique to achieve arthrodesis of the hallucal interphalangeal joint. Stabilization is achieved by external fixation with crossing Kirschner wires joined together to create a single functional unit, a technique that avoids common problems often associated with Kirschner-wire fixation. The authors propose that this simple technique be considered for patients in whom it has been determined that screw fixation should not be used to obtain fusion of the interphalangeal joint.

The structure, classification, function, and regulation of matrix metalloproteinases in normal and abnormal wound healing is discussed. Results from key studies suggest that neutrophil-derived matrix metalloproteinase 8 (MMP-8) is the predominant collagenase present in normal healing wounds, and that overexpression and activation of this collagenase may be involved in the pathogenesis of nonhealing chronic leg ulcers. Excessive collagenolytic activity in these chronic wounds is possible because of the reduced levels of tissue inhibitor metalloproteinase 1 (TIMP-1). However, until recently, there have been no studies evaluating levels of matrix metalloproteinase or tissue inhibitors of metalloproteinase activity in chronic diabetic foot wounds. Improving basic knowledge and pharmaceutical intervention in this area ultimately may help clinicians identify and proactively intervene in an effort to prevent normal wounds from becoming chronic. This may prevent the high prevalence of morbidity associated with this significant health problem. (J Am Podiatr Med Assoc 92(1): 12-18, 2002)
Cellular Senescence and Matrix Metalloproteinase Activity in Chronic Wounds
Relevance to Debridement and New Technologies
A prolonged inflammatory response may adversely affect wound closure. Delayed wound closure and extended exposure to chronic wound fluid may also affect cellular activity in a wound bed and result in cellular senescence. Prolonged inflammation and cellular senescence may adversely affect the efficacy of topically-applied biological agents, including growth factors. Appropriate wound bed preparation and debridement are necessary to improve clinical outcomes of new technologies.(J Am Podiatr Med Assoc 92(1): 34-37, 2002)
Retrocalcaneal Exostosis
Anatomy and a New Surgical Approach
Various procedures have been described for removing a retrocalcaneal exostosis. These procedures require partial or complete detachment of the insertion of the Achilles tendon and ultimate resection of the exostosis. The authors introduce a simplified technique to surgically excise a retrocalcaneal exostosis based on an important and newly reported anatomical relationship. The procedure is performed through a posterior transverse incision and requires little or no reflection of the Achilles tendon. Overall, the 14 patients studied retrospectively wore shoes and returned to usual activities fairly rapidly after this procedure; however, time until patients were free of pain averaged nearly 12 months. Two patients did not obtain relief and required additional surgery despite complete removal of the exostosis. These results challenge the assumption that retrocalcaneal pain is secondary to exostosis formation. (J Am Podiatr Med Assoc 92(10): 537-542, 2002)
Chemical matrixectomy using phenol is one of the most common surgical procedures for the permanent removal of toenails. The concentration of phenol solution and duration of its application have varied widely and have not been subjected to scientific study. The authors studied the histologic effects of phenol on the nail matrix and determined the optimal concentration of phenol and time the phenol solution needs to be in contact with the nail bed.

Approximately 36 million women in the United States are in the postmenopausal phase of life, creating unique challenges for the provision of compassionate, comprehensive podiatric medical treatment. Long-term estrogen deprivation arising from menopause in association with age-related factors disproportionately increases the risk of ischemic heart disease, osteoporosis, and concomitant podiatric complications. This article discusses the physiologic basis of menopause, hormone replacement therapy and its effects on osteoporosis, and other podiatric implications of menopause. Podiatric physicians caring for larger numbers of peri- and postmenopausal women must formulate a comprehensive management plan for treating fractures that arise from a combination of estrogen-deprivation osteoporosis and abnormal foot biomechanics.
