Review Case Reports
Liquid Adhesive Contact Dermatitis After Bunionectomy: A Case Report and Literature Review.
Hypersensitivity reactions to the skin adherents used in postoperative dressings are an uncommon but unfavorable complication that can result in poor wound healing, increased scarring, and surgical wound infections. This unexpected and unforeseen complication is not well documented in the current published data. We present the case of a 39-year-old female who had undergone a bunionectomy procedure and developed allergic contact dermatitis postoperatively. ⋯ The various ingredients in liquid adhesives contain known allergen compounds that can cause a reaction, such as balsam of Peru and colophony or rosin, both of which are reviewed in our report. We also present a treatment algorithm developed from the compiled data in the case of a patient developing an allergic reaction. From our literature review and considering the percentage of incidence, if a surgeon desires to use a liquid adhesive product, Mastisol(®) should be chosen because of its lower reactivity and greater adhesive properties compared with the compound tincture of benzoin.

Comparative Study
A Biomechanical Comparison of Locking Versus Conventional Plate Fixation for Distal Fibula Fractures in Trimalleolar Ankle Injuries.
Previous biomechanical studies have advocated the use of locking plates for isolated distal fibula fractures in osteoporotic bone. Complex rotational ankle injuries involve an increased number of fractures, which can result in instability, potentially requiring the same fixed angle properties afforded by locking plates. However, the mechanical indication for locking plate technology has not been tested in this fracture model. ⋯ No statistically significant differences were found between the locking and conventional plate constructs during both fatigue and torque to failure testing (p > .05). Our specimen bone mineral density averages did not represent poor bone quality. The clinical implication of the present study is that distal fibular locking plates do not provide a mechanical advantage for trimalleolar ankle injuries in individuals with normal bone density and in the absence of fracture comminution.

The analgesic effects of preoperative ultrasound-guided nerve blocks wear off after about 12 hours, leaving some patients in substantial pain. Transdermal fentanyl concentrations peak at 12 to 24 hours after application and maintain this concentration for approximately 72 hours. We sought to determine whether combining the use of a transdermal fentanyl patch with either a sciatic or femoral-sciatic nerve block would improve pain control in patients undergoing foot and/or ankle surgery. ⋯ The mean pain scores were also lower in the treatment group, with a statistically significant difference (p < .05) at 12, 24, and 48 hours. Thus, patients receiving a fentanyl patch combined with an ultrasound-guided nerve block required less supplemental analgesia to maintain adequate pain control than did those receiving a nerve block alone. In conclusion, a fentanyl patch is a useful adjunct to an ultrasound-guided nerve block in foot and ankle surgery.

Fracture of the posterior process of the talus with concomitant subtalar dislocation is rare; thus, the mechanism of injury, appropriate treatment, and prognosis are unclear. We report the case of a 50-year-old male with a fracture of the posterior process of the talus with concomitant subtalar dislocation that was recognized early and successfully treated operatively.

Previous biomechanical studies have shown that the gift box technique for open Achilles tendon repair is twice as strong as a Krackow repair. The technique incorporates a paramedian skin incision with a midline paratenon incision, and a modification of the Krackow stitch is used to reinforce the repair. The wound is closed in layers such that the paratenon repair is offset from paramedian skin incision, further protecting the repair. ⋯ We present the outcomes data from patients who had undergone this alternative technique for Achilles tendon repair. The technique is reproducible, with good patient satisfaction and return to activity. The results compared well with the historical repeat rupture rates and incidence of nerve injury and dehiscence for open and percutaneous Achilles tendon repairs.
