Purpose: Problematic late sequelae are common following a calcaneal fracture regardless of the initial treatment. We retrospectively evaluated the painful conditions and reviewed the results of the operative treatment in patients with previously treated calcaneal fractures. Materials and Methods: Between October 1996 and September 2001, forty-three patients who underwent subsequent surgical treatment for late sequelae of calcaneal fracture were reviewed. The initial treatment consisted of only immobilization in a cast in 7 patients, closed reduction with pin fixation (Essex-Lopresti technique) in 22 and open reduction and internal fixation in 14. Painful conditions in the hind foot included subtalar arthritis in 31 patients, calcaneofibular impingement in 13, peroneal tendinitis in 6, displaced posterior bony fragment in 3, sural neuritis in 2, subtalar and midtarsal arthritis in 1 and displaced plantar bony fragment in 1. The surgical procedures for the late complications were performed at a mean of 19 months (range, 6 to 35 months) after the injury and consisted of lateral wall ostectomy and in situ subtalar fusion in 28 patients, only lateral wall ostectomy in 5 patients, lateral wall ostectomy and subtalar distraction arthrodesis in 3, removal of displaced posterior bony fragment in 3, sural nerve transposition in the peroneus brevis in 2, triple arthrodesis in 1 and removal of displaced plantar bony fragment in 1. Mean postoperative follow up period was 57 months (range, 33 to 82 months). The results of treatment were evaluated on the basis of pain, improvement in the ability to perform activities of daily living, to return to work or to a pre-injury level of activity. Results: Pain was partially relieved in 38 patients (88%), but not relieved in 5. Function improved in 34 patients (79%), and 32 (74%) returned to work or to a pre-injury level of activity. There was a trend that the longer the interval between the injury and the operation, the longer the subsequent interval until the patient returned to full activities or work. Conclusion: Meticulous physical examination and intensive prompt treatment for remaining pain after initial treatment of calcaneal fractures are recommended for patient's satisfaction and returning to work.
AcciMap, STAMP, FRAM을 이용한 반응기 세척 작업 중 화재 사고 분석

Representative systematic accident analysis methods proposed so far include AcciMap, STAMP, and FRAM. This study used these three techniques to analyze a fire accident case that occurred during routine manufacturing work in a domestic chemical plant and compared the results. The methods used different approaches to identify the cause of the accident, but they all highlighted similar causal factors. In addition to technical issues, the three accident analysis methods identified factors related to safety education, risk assessment, and the operation of the process safety management system, as well as management philosophy and company culture as problems. The AcciMap and STAMP models play complementary roles because they use hierarchical structures, while FRAM is more effective in analyses centered on human and organizational functions than in technical analyses.

An unstable second metatarsophalangeal joint may produce pain in the forefoot. Plication of stretched lateral ligament and capsule and transfer of the extensor digitorum brevis under the transverse intermetatarsal ligament performed as the primary procedure to stabilize this painful joint. But the pain was not subsided and the proximal phalanx was resubluxated. So, we osteotomized the second metatarsal to restore a normal alignment of the second toe. Then the symptom was subsided. We report a case of painful instability of the metatarsophalangeal joint of the second toe.
