The article offers a brief history of pitted keratolysis (PK), research regarding PK etiology, evaluation of PK, and current treatment modalities. The main objective of this article focuses on the current literature on PK, its presentation and symptomatology, prevalence, and available therapeutic options. We present a case report and review on PK of a patient treated with an over the counter antiperspirant, topical erythromycin, oral erythromycin, and proper education on hygiene, with complete resolution and without recurrence after a follow up of greater than 12 months.

Category: Hindfoot Introduction/Purpose: Autogenous bone graft remains the standard bone graft in foot and ankle surgery when filling a bone void or adding biology to an arthrodesis site. Harvesting autograft can have serious donor site morbidity with an average complication rate of 8% and reports as high as 25%. Complications range from persistent pain to severe infection. Most procedures in the foot and ankle require only a small volume of graft. Using a small reaming graft harvester, surgeons can harvest autograft from the ipsilateral calcaneus. This is done within the same surgical field and requires minimal additional operative time. The purpose of this article is to review a population of patients who underwent calcaneal autograft harvesting with a reaming graft harvester and evaluate the outcomes of the procedure. Methods: From August 2015 to February 2018, all patients who underwent calcaneal autograft harvesting by a single surgeon were identified and reviewed. Patients were included if they had autograft harvested from the calcaneus on the ipsilateral operative limb using a reamer bone graft harvester and if they had complete clinical follow up of at least 6 months. Patients were excluded if they had autograft from a site other than the ipsilateral calcaneus, had a previous harvest from the ipsilateral calcaneus, or if they did not have full follow up of at least 6 months. Outcomes of interest were major and minor complications, intra- operative complications, and long term radiographic findings. Patients required graft for numerous primary procedures including a variety of arthrodesis or filling of bone voids. Postoperative protocols and return to weightbearing times varied with the accepted protocols for the primary procedure. Results: 300 patients were identified and met inclusion criteria. Average follow up was 12.6 months. There was 1 major complication (0.3%) consisting of a calcaneal stress fracture that healed with a period of 4 weeks of non weightbearing followed by 4 weeks of protected weightbearing. There were 3 minor complications (1%) consisting of transient painful scar and medial heel pain that all resolved uneventfully. There were no intraoperative complications while performing the 300 procedures. There were no incidences of neurovascular damage. Of the patients with over 1 year radiographic follow up, all harvest sites were still visible on lateral plain film radiographs. Conclusion: Using a small reamer to harvest calcaneal autograft for foot and ankle surgeries that require a small to moderate amount of bone graft is safe and effective. Approximately 4 cc of graft can be harvested very quickly without needing to prepare another surgical site for harvesting. The complication rate for harvesting calcaneal autograft was found to be extremely low in this study, despite the harvest site remaining visible on radiographs past 1 year. The proposed technique can be extremely useful to the foot and ankle surgeon.
