Circumflex Accessory Branch of the Superficial Fibular Nerve: An Unusual Cause of Nerve Entrapment.

The superficial fibular (peroneal) nerve traditionally courses through the anterolateral deep leg and pierces the deep crural fascia at the lower leg to divide into its terminal branches. Entrapment of the superficial fibular nerve is most commonly documented to occur at where it pierces the deep fascia, and numerous etiologies causing entrapment are described. In this case report, we describe an unusual cause of entrapment from a tertiary branch of the superficial fibular nerve taking a circumflex course and wrapping around the secondary branch of the main nerve. This was successfully treated by surgical excision. To the best of our knowledge, this cause of entrapment has not been described in the literature at the time of this publication.

Synovial chondromatosis of the ankle joint: 2 cases treated by open arthrotomy and synovectomy.

Synovial chondromatosis is a rare condition consisting of metaplasia of the synovial tissue that usually presents in large joints such as the knee and hip. The reported occurrence of synovial chondromatosis in the foot and ankle joints is rare in the literature. In this case report, the successful surgical management of two patients presenting with this condition using open ankle arthrotomy & synovectomy is described. These two cases are presented to provide added depth to the current literature, as well as presenting a review of published literature to further guide clinicians in the management of this rare condition. LEVEL OF EVIDENCE: 4 (case study).

Medial Plantar Artery Common Origin to Determine Incision Placement for the Fasciocutaneous Flap: A Cadaveric Study.

Medial plantar artery-based flaps have great value in healing full-thickness wounds of the foot and ankle. The goal of this study was to identify a common location for the origin of the medial plantar artery. Recognition of this anatomic marker will help improve incision placement and increase the success of preserving the artery when performing the medial plantar artery fasciocutaneous flap. This study examined the location of the origin of the medial plantar artery in 40 fresh cadavers. Results were obtained by dissection and macroscopic analysis to document the distance of the origin of the medial plantar artery from the intercollicular groove of the medial malleolus in centimeters. The mean distance was determined to be 3.2 ± 0.4 cm (range 2.7 to 4.5), with a low standard error of 0.0621. This suggests a high statistical probability that the common origin of the medial plantar artery is found 3.2 cm distal to the intercollicular groove of the medial malleolus in the general population.

Impact of podiatry resident experience level in hallux valgus surgery on postoperative outcomes.

BACKGROUND: Despite modern advancements in transosseous fixation and operative technique, hallux valgus (i.e., bunion) surgery is still associated with a higher than usual amount of patient dissatisfaction and is generally recognized as a complex and nuanced procedure requiring precise osseous and capsulotendon balancing. It stands to reason then that familiarity and skill level of trainee surgeons might impact surgical outcomes in this surgery. The aim of this study was to determine whether podiatry resident experience level influences midterm outcomes in hallux valgus surgery (HVS). METHODS: Consecutive adults who underwent isolated HVS via distal metatarsal osteotomy at a single US metropolitan teaching hospital from January 2004 to January 2009 were contacted and asked to complete a validated outcome measure of foot health (Manchester-Oxford Foot Questionnaire) regarding their operated foot. Resident experience level was quantified using the surgical logs for the primary resident of record at the time of each case. Associations were assessed using linear and logistic regression analyses. RESULTS: A total of 102 adult patients (n = 102 feet) agreed to participate with a mean age of 46.8 years (standard deviation 13.1, range 18-71) and average length of follow-up 6.2 y (standard deviation 1.4, range 3.6-8.6). Level of trainee experience was not associated with postoperative outcomes in either the univariate (odds ratio 0.99 [95% confidence interval, 0.98-1.01], P = 0.827) or multivariate analyses (odds ratio 1.00 [95% confidence interval, 0.97-1.02], P = 0.907). CONCLUSIONS: We conclude that podiatry resident level of experience in HVS does not contribute appreciably to postoperative clinical outcomes.
