Background: Many authors have reported that an ankle varus deformity more than 10 to 15 degrees may be the cause of failures in total arthroplasty. Our study aim was analyze short-term outcomes arthroplasty with additional procedures accompanied by 20 deformity. Methods: Among patients who received for end-stage osteoarthritis between June 2006 and May 2012, 103 cases were followed 6 months reviewed. Depending on degree deformity, 24 coronal allocated into group A, 79 less B. Soft tissue...
The purpose of this study was to evaluate the surgical outcomes reconstruction chronic Achilles tendon ruptures using various methods, including allograft. Between October 2003 and March 2010, twelve patients with a defect gap >4 cm underwent V-Y advancement, gastrocnemius fascial turn-down flap, flexor hallucis longus transfer, or group comprised 11 men 1 woman. At last follow-up, all were assessed regard postoperative complications, self-reported level satisfaction, American Orthopaedic...
The purpose of this study was to identify the intermalleolar ligament morphologically and correlate its shape with MR images.Seventy-seven ankles were used in study. After had been located posterior ankle space, medial lateral attaching sites identified, length, width, thickness measured. MRI performed on 26 before they dissected (20 specimens) or serially sectioned (six specimens). serial sections taken at a 2 mm sagittal horizontal directions.The observed 81.8% specimens composed more than...
Background: The management of an ossicle or avulsion fragment the fibular tip in chronic lateral ankle instability is open question. Some authors maintain necessity osteosynthesis for reconstruction ligamentous structure if large. We hypothesized that modified Broström procedure with resection would result good outcomes compared to same patients without ossicle. Methods: Between December 2004 and 2010, 102 underwent instability. Of these, 82 (86 ankles) were available this study. Forty...
It has been reported that the operative outcome of tarsal tunnel syndrome caused by space-occupying lesions is more favorable than those other reasons. The purpose this clinical study was to report our results after surgical treatment for benign lesions.From July 2004 February 2007, 20 patients underwent decompression in institution. Out them, 13 cases were due around tunnel. average age 51.3 and mean symptom duration 16.5 months. operation included complete release removal lesion. outcomes...
Background: The effect of lateral soft tissue release (LSTR) regarding the position sesamoid is not clear. purpose this study was to evaluate LSTR by comparing radiologic and clinical outcomes operative treatment for hallux valgus with or without LSTR. Methods: This included a consecutive series chevron osteotomy 119 feet 90 patients symptomatic incongruent first metatarsophalangeal (MTP) joints. Fifty-one underwent an operation procedure (LSTR group), remaining 68 (control non-LSTR group)....
Background: Dexmedetomidine is widely used for conscious sedation in patients undergoing lower-extremity surgery under regional anesthesia. We evaluated the postoperative analgesic effects of intravenous dexmedetomidine given during ankle spinal Methods: Forty-three participants underwent repair lateral angle ligaments For surgery, were allocated to a group (n=22) that received loading dose 1 mcg.kg-1 over 10 min, followed by maintenance 0.2-0.7 μg.kg-1.h-1; and propofol (n=21) an effective...
We retrospectively evaluated early outcome and conducted this study to determine the predictive factors for percutaneous cardiopulmonary support (PCPS) weaning hospital discharge. From January 2004 December 2006, 92 patients diagnosed as cardiac or respiratory failure underwent PCPS using Capiox emergent bypass system (Terumo, Tokyo, Japan). The mean+/-S.D. age was 56+/-18 (range, 14-85) years 59 (64%) were male. mean duration of 90.9+/-126.0 h that resuscitation (CPR) 51.1+/-27.8 min. rate...
We report a case of subcutaneous infection in 55-yr-old Korean diabetic patient who presented with cystic mass the ankle.Black fungal colonies were observed after culturing on blood and Sabouraud dextrose agar.On microscopic observation, septated ellipsoidal or cylindrical conidia accumulating an annellide visualized staining lactophenol cotton blue.The organism was identified as Exophiala salmonis by sequencing ribosomal DNA internal transcribed spacer region.Phaeohyphomycosis is...
Hereditary sensory and autonomic neuropathy type IV is an autosomal recessive disorder characterized by severe mental retardation self-mutilation-related complications. Recently, we investigated a 16-year-old Korean boy with normal intelligence. He had preserved pain sensation but was suspected of having hereditary because the recurrent bone fractures painless joint destruction in absence any predisposing medical conditions. Genetic analysis NTRK1 gene revealed compound heterozygous...
Pediatric-type sarcomas such as Ewing's sarcoma (EWS)/primitive neuroectodermal tumor family and rhabdomyosarcoma are relatively uncommon in adult patients. Optimal treatment strategies for this population prognosis patients compared with pediatric remain controversial.We retrospectively reviewed pediatric-type older than 15 years at a single institution.A total of 84 consecutive between 1995 2009 were identified the Samsung Medical Center, Seoul, Korea. Median age was 30 range 15-74 years....
Acquired adult flatfoot is a deformity characterized by decreased medial longitudinal arch and hindfoot valgus with or without forefoot abduction. The etiologies of this include posterior tibial tendon dysfunction, rheumatoid arthritis, trauma, Charcot's joint, neurologic deficit, damage to the spring ligament complex plantar fascia. Among these, dysfunction most well-known cause. Although has been regarded as synonym acquired flatfoot, failure ligaments supporting can also result in...
Chronic lateral ankle instability is a major complication of acute sprains, which can cause discomfort in both daily and sports activity. In addition, it may result degenerative changes to the joint long term. An accurate diagnostic approach successful treatment plan be established based on comprehensive understanding concept functional mechanical instability. The patients' history correct physical examination would first most important step. hindfoot alignment, competence ligaments,...
