Primary Septoplasty in the Treatment of Nasal Bone Fractures

PURPOSE: Most of nasal bone fractures involve the septum; either or both of the ethmoidal perpendicular plate(EPP) and quadrangular cartilage(QC). Unlocked tension from the underlying quadrangular cartilage and poorly reduced bony septum are obstacles to the successful reduction of nasal bone. So we compared the preliminary outcome of septoplasty as a primary treatment with the untreated septum in nasal bone fractures. METHODS: We performed a retrospective study of 215 patients who underwent reduction of nasal fracture from January 2002 to February 2008. We graded patients into four groups according to the amount of deviation and direction of force by CT. Our indication for septoplasty and combined procedures was the deviation of EPP or QC over 50% from the midline. We interviewed part of the patients by telephone regarding the subjective esthetic and functional outcomes. RESULTS: Forty five of 215 patients (21 percent) underwent septoplasty and combined procedures (cartilage graft, etc) after the informed consent. The patients who underwent septoplasty significantly were satisfied with the outcome of esthetic appearance and nasal patency compared with the patients who underwent simple closed reduction despite of having septal deviation over 50 percent from the midline(p<0.05). CONCLUSION: Septal surgery and esthetic consideration shoud be made even in simple nasal reductions. And if CT scans reveal severe deviation of septum, septoplasty should be considered as a primary treatment.

Prevalence of Fungal Infection in Diabetic Foot Ulcer

PURPOSE: In a diabetic foot ulcer, superficial fungal infection of the foot may disrupt the skin integrity and provide an avenue for bacterial infection. The prevalence of fungal infection in diabetic foot ulcer has been reported as 12-30% in Caucasian patients. However, no data are available for Korean patients. The purpose of the study was to examine the prevalence of fungal infection in diabetic foot patients admitted in our clinic. METHODS: This study included consecutive 30 diabetic foot ulcer patients(24 males and 6 females) admitted from May 2007 to July 2007. The mean age was 60.5 years. All patients underwent mycological examination including direct microscopic examination in KOH and culturing on slants and tubes with Sabouraud's glucose agar. RESULTS: Clinical signs of presumed fungal infection, which were examined by dermatologists, were found in all patients included in this study. Direct microscopic examination was positive for the specimens of the skin and the toenails in 28(93.3%) and 25(83.3%) patients, respectively. In addition, culture result was positive for the specimens of the skin and the toenails in 5(16.73%) and 7(23.3%) patients, respectively. CONCLUSION: The prevalence of fungal infection in diabetic foot ulcer patients admitted in our clinic is much higher than that in Caucasian patients(83.3-93.3% vs 12-30%).

Total Hip Arthroplasty for Fused Hips / 대한정형외과학회잡지

The conversion of the fused hip to THA may be used for patients with painful pseudoarthrosis, and malposition of the arthrodesed hip. It may also be used for patients with disabling pain in the ipsilateral knee, contralateral hip or lower back. Nineteen fused hips have been converted to total hip arthroplasty from January 1985 to December 1993. They were followed up for an average of 6 years. The causes of the fused hip were post-traumatic osteoarthritis (8 cases), tuberculous arthritis (6 cases), ankylosing spondylitis (3 cases) and rheumatoid arthritis (2 cases). The results of THA were satisfactory in all cases. The average Harris hip score after THA was improved from 56 to 84.1. The results of THA were best in patients with tuberculous arthritis and poorest in patients with ankylosing spondylitis. The average range of motion after THA is as follows: flexion 82 degree, abduction 28 degree, adduction 16 degree, external rotation 27 degree and internal rotation 13 degree. The average leg length discrepancy improved from 3 cm to 1.5 cm. The conversion of the fused hip to THA improves the patient s quality of life, so it is a useful treatment for the fused hip.

Septic Hip in a Child due to H.influenzae: Problems with a Recent Experience / 대한정형외과학회잡지

We report a case of acute septic arthritis of the hip in a child due to H. influenzae with review of the problems encountered. A one year and 9 months-old male child was admitted because of fever, limping and restlessness of 48-hour duration. Under the impression of septic arthritis of the right hip, blind broad-spectrum antibiotic regimen was initially instituted. Fever subsided immediately and two blood cultures yielded no growth, as did joint tapping. But fever recurred on the 8th day of admission. MRI demonstrated fluid collection in the right hip. Arthrotomy yielded thin pus. The antibiotic regimen was shifted to vancomycin, according to the culture report of S. aureus. However, spiking fever continued. On the 4th week of admission, recheck MRI demonstrated fluid collection in and out of the hip joint. A second arthrotomy yielded frank pus. H. influenzae was reported in pus culture for the first time, being susceptive only to chloramphenicol. Fever was down to normal temperature after injection of urfamycin. Radiograph on the 17th day after the 2nd arthrotomy revealed posterior dislocation of the right hip. MRI demonstrated granulation tissue within the acetabulum. Open reduction confirmed granulation tissue without pus. This case suggests: 1. Routine blind antibiotic regimen for gram-positive and negative organisms in the initial phase of treatment may fail in the rare case of H. influenzae. This may lead the surgeon to miss the optimum time of surgical intervention despite early diagnosis, 2. Arthrotomy may fail if not followed by antibiotics sensitive to the pathogen. 3. Delayed pathologic dislocation may ensue due to invasion of granulation tissue.

Two-Stage Reimplantation for the Treatment of Infected Total Knee Arthroplasty / 대한정형외과학회잡지

Deep infection following arthroplasty of the knee is a serious complication resulting in pain, discharge and loss of function. The incidence of deep infection ranges from 1% to 2% in a majority of reported series. There are several options for treatment of infected total knee arthroplasty: (1) antibiotic suppression, (2) debridement, (3) resection arthroplasty, (4) reimplantation, (5) arthrodesis, (6) amputation. Among them, recent reports have favored a two-staged regimen exchanging the prosthesis in an infected knee by using an antibiotic impregnated cement spacer. The result of our study support this option for treatment. We have experienced 14 cases of two-staged reimplantation in infected total knee arthroplasty, diagnosed according to the criteria described by Bengstons and followed up for more than two years. The average interval from prosthesis removal to revision was 6.85 weeks. Prior to revision, the average knee score was 50 points, and the average range of motion was 74 degree. After revision, the average knee score was 81 points. The average range of motion was 95 degree. Our protocol for the treatment successfully eradicated the deep infection in 13 patients, only a patients who had severe rheumatoid arthritis was the sole documented case of reinfection.

Fracture of the Ipsilateral Femur after Total Hip Arthroplasty / 대한정형외과학회잡지

PURPOSE: Although considered uncommon, periprosthetic fracture of the femur after hip arthroplasty is a serious complication that can be difficult to treat. Authors analyzed the types of fracture and modality of treatment. MATERIALS AND METHODS: Between Jan. 1983 and Dec. 1997, 17 cases of postoperative periprosthetic fractures had been treated at our hospital. These cases were followed up for an average of 58 (13-123) months. The fractures were classified according to Duncan and Masri classification. Three cases of type A, and 6 cases of type B1, 3 cases of type B2, 3 cases of type B3 and 2 cases of type C. The 3 cases of type A and 2 cases oftype B1 were conservative treatments. The 4 cases of type B1 were treated with open reduction and internal fixation with bone graft. The 3 cases of type B2 and 3 cases in type B3 were treated with long stem revision. The 2 cases of type C were treated with open reduction and internal fixation with bone graft. RESULTS: Bony union happened in all cases. The results according to Beals and Tower criteria were excellent in 12 cases, good in 3 cases and poor in 2 cases. CONCLUSIONS: The most frequent cause of periprostic fracture was trauma and other causes were loosening and osteolysis. Proper treatment method of periprosthetic fracture were important for stability of femoral stem
