RESUMEN
Purpose@#This study devised triple tension band wirings (TTBW) fixation in patients with comminuted patella fractures to compare the clinical result of TTBW with that of tension band wiring (TBW). @*Materials and Methods@#This study was conducted on 91 patients who had undergone surgery diagnosed with acute patella fracture from January 2011 to December 2016. The study included 51 double TBW patients (Group 1) and 40 patients with TTBW (Group 2). @*Results@#Five out of 51 cases had a loss of reduction and fixation failure in Group 1, and no failure of fracture formation healing occurred in Group 2. Nonunion was noted in one case in Group 1 and no case in Group 2. Eight K-wire migration cases were observed in Group 1, which was not observed in Group 2. Six patients in Group 1 underwent revisional surgery. No patients in Group 2 had a reoperation. As a result of a one-year follow-up after the operation, the mean range of motion of the knee joint in groups 1 and 2 was 128.3°±11.3° and 127.9°±10.8°, respectively. The Lysholm’s scores for groups 1 and 2 were 90.8±4.2 and 90.3±3.8 points, respectively, which was not statistically significant. @*Conclusion@#TTBW is a helpful technique for the surgical treatment of comminuted patella fractures. The TTBW method has less reoperation due to nonunion and fixation failure. After a one-year followup, the clinical results were similar to the conventional TBW method.
RESUMEN
Purpose@#To evaluate the results of intramedullary nailing with sliding restriction and dynamization methods in treating intertrochanteric fractures. @*Materials and Methods@#From August 2016 to March 2019, patients aged 65 years and older who underwent intramedullary nailing in treating intertrochanteric fractures were enrolled in this study. The radiological and clinical results were analyzed in 49 patients who had undergone lag screw sliding re-striction and dynamization of the distal interlocking screw method. @*Results@#Forty-seven patients achieved union without complications (95.9%). The mean union period was 6.5 weeks (range, 6-9 weeks). Complications occurred in two patients (4.1%), including the cut through of the lag screw in one patient and varus deformity of more than 10° in the other. The preinjury mean Koval grade was 2.8 (range, 1-7). The mean was 3.3 (range, 1-7) at the final follow-up, and the mean difference was 0.5 (range, 0-2). @*Conclusion@#Intramedullary nailing with a sliding restriction and dynamization method for treating in-tertrochanteric fractures achieved union. The reduction achieved during surgery was maintained with good clinical results. This method is a safe and effective treatment technique for femoral intertrochanteric fractures.
RESUMEN
Background@#We aimed to investigate the current trend of joint replacement surgery incidence in patients with rheumatoid arthritis (RA) in South Korea and to compare the incidence of joint replacement surgery in each affected joint. @*Methods@#We performed this big data analysis to investigate the current trend of joint replacement surgery incidence in patients with RA in South Korea and to compare the incidence of joint replacement surgery in each affected joint. This retrospective study was based on data from the Korea National Health Insurance claims database. @*Results@#The prevalence of RA increased every year (0.13% in 2008, 0.25% in 2016). The number of newly diagnosed patients increased from 29,184 in 2010 to 38,347 in 2016. The incidence rate of joint replacement surgery in patients with RA increased from 0.72% in 2010 to 4.03% in 2016. The knee (68.3%) was the most commonly replaced joint. The relative risk (RR) of additional joint replacement surgery was highest for the shoulder joint (RR,1.454; 95% confidence interval, 0.763–2.771). The median time from diagnosis to surgery was the shortest in the elbow joint (379 days) and the longest in the shoulder joint (955 days). The median time for each joint was short in order of the elbows, ankles, hips, knees, and shoulders (p < 0.01). @*Conclusions@#The most frequently and initially replaced joints were different, but the prevalence and incidence of RA, as well as those of joint replacement surgery, have recently increased in South Korea. Joint replacement surgery in RA was the highest for the knee joint. The median time from diagnosis to surgery was shortest for the elbow, followed by the ankle, hip, knee, and shoulder. Regardless of whether patients are symptomatic, evaluation of large joints such as the knee, elbow, ankle, and hip should be considered from an early stage.
RESUMEN
Purpose@#To compare the short-term clinical and radiologic outcomes of combined posterior cruciate ligament (PCL) and posterolateral complex (PLC) reconstruction to those of isolated PCL reconstruction (PCLR) for patients with posterolateral knee laxity less than grade III. @*Materials and Methods@#We retrospectively reviewed 49 patients (51 knees) who underwent PCLR between January 2008 and December 2015. Patients with a minimum follow-up of 24 months were included and divided into two groups (group A, isolated PCLR; group B, combined PCL and PLC reconstruction). Clinical outcomes were evaluated as the International Knee Documentation Committee (IKDC) subjective, Lysholm, and Tegner activity scale scores. Radiologic outcomes were also assessed using the side-to-side differences in posterior tibial translation via stress radiographs. @*Results@#A total of 30 cases were analyzed. There were no significant differences in the Lysholm and Tegner activity scale scores between the two groups preoperatively and at the final follow-up. However, group B showed a higher IKDC subjective score compared to group A at the final follow-up (group A, 72.8±8.9; group B, 77.7±10.1; p<0.05). Regarding the radiologic outcomes, group B also showed a significantly less side-to-side difference in posterior tibial translation compared to group A at the final follow-up (group A, 4.8±2.3 mm; group B, 3.8±2.1 mm; p<0.05). @*Conclusion@#Combined PCL and PLC reconstruction resulted in improved clinical and radiologic outcomes than isolated PCLR in patients who have less than grade III posterolateral laxity of the knee. In cases of PCL rupture with ambiguous PLC injury, combined PCL and PLC reconstruction may help to improve posterior residual laxity of the knee.
RESUMEN
Corynebacterium striatum (C. striatum ) is an aerobic Gram-positive rod, which is an organism of the respiratory tract and skin. Because of its low virulence, it is usually thought to be a contaminant even if it is shown in culture tests, but it can cause endocarditis and respiratory infections, and rarely meningitis and arthritis. Infection with C. striatum has been reported in patients with reduced immunity, as well as in patients with catheter or broken skin barriers. Septic knee arthritis caused by C. striatum infection is rarely reported, and knee joint infection by C. striatum in patients who underwent arthroscopic debridement for previous septic arthritis is even more rare. Therefore, we report a case of septic knee arthritis caused by C. striatum that was improved by early diagnosis and arthroscopic treatment.
RESUMEN
Synovial chondromatosis is a proliferative chondrogenic benign tumor originating from the synovial membrane of the joint. Radiological findings occupy an important part in the diagnosis of patients with synovial chondromatosis, which appear in various forms, and are often misunderstood such as tuberculous arthritis and rheumatoid arthritis. In many cases, the findings of rice body, which are common in tuberculous arthritis and rheumatoid arthritis, and synovial chondromatosis are similar on magnetic resonance imaging. A case of primary synovial chondromatosis that was mistaken for tuberculous arthritis or rheumatoid arthritis by imaging findings is reported.
RESUMEN
Purpose@#This study examined the effect of lag screw insertion on proximal fragments by separating the right and left sides of intertrochanteric fractures in elderly patients that underwent intramedullary nailing. @*Materials and Methods@#Patients aged ≥65 years that underwent intramedullary nailing after a diag-nosis of intertrochanteric fractures during the period February 2012 to May 2016 were included in the study. The subjects were divided into right and left side groups. The effect of the clockwise rotational force generated when a lag screw was inserted on the proximal fragment was evaluated in both groups. @*Results@#In the right and left groups, most proximal fragments were located in the intramedullary canal after surgery (45 cases [75.0%] and 67 cases [73.6%], respectively). Clockwise rotation due to lag screw placement in the right group occurred in two cases (3.3%), which both showed internal rotation, and in four cases (4.4%) in the left group, all of which showed external rotation. @*Conclusion@#After intramedullary nailing of intertrochanteric fractures in elderly patients, proximal fragments were mostly located in the intramedullary cavity. The results obtained confirmed that the clockwise rotational force generated by lag screw insertion did not affect left or right sides.

RESUMEN
Purpose@#This study examined the effects of the postoperative administration of parathyroid hormone (PTH) on fracture healing in intertrochanteric fractures accompanied by osteoporosis in elderly females. @*Materials and Methods@#Female patients aged 65 years and more who underwent surgery after a diagnosis of intertrochanteric fractures and osteoporosis during the period from July 2013 to December 2017 were included as subjects. The subjects were divided into two groups: PTH-treated group and non-PTH-treated group. The formation time of the first callus, timing of the bridging callus, and time of bony union for both groups were evaluated. @*Results@#In the PTH-treated group, the mean time of the first callus formation, average time of bridging callus, and the average time of bony union were 32, 58, 83 days, respectively, which were significantly shorter than that of the untreated group. @*Conclusion@#PTH, a treatment for osteoporosis, promotes callus formation and the healing process. Therefore it will be helpful in intertrochanteric fractures accompanied by osteoporosis in elderly females.
RESUMEN
Gout occurs mainly in monoarthritis and is found in more than 50% of cases in hallux of the foot. In addition, symptoms sometimes begin in the hand, wrist, and elbow, but they are rarely observed in the spine. The patient was referred for tuberculous polyarthritis due to antituberculosis drug failure. Inflammatory findings were observed in the lumbar, elbow, wrist, hand and foot areas. Surgery was performed on the foot area and a pathology diagnosis revealed gouty arthritis. We report this case with a review of the relevant literature.

Recently, we experienced a case where the diagnosis and management of a deep femoral artery rupture was delayed. This vascular complication occurred during the insertion of a distal interlocking screw of a proximal femoral nail for the fixation of an intertrochanteric femur fracture. A 79-year-old male patient was diagnosed with a right intertrochanteric fracture after a fall. We fixed the fracture with a proximal femoral nail (Zimmer® Natural Nail™ System). One day after the procedure, the patient complained of pain and swelling on the anteromedial side of his middle thigh followed by hypotension, anemia and prolonged thigh swelling. Computed tomography angiography was performed 7 days after the procedure. We found a pseudoaneurysm of the perforating artery caused by injury to the deep femoral artery and an intramuscular hematoma in the anterior thigh muscle. We successfully treated the pseudoaneurysm using coil embolization. Throughout the management of intertrochanteric femoral fractures, it is important to be aware and monitor signs and symptoms related to the possibility of blood vessel damage. When a patient presents with swelling and pain on the middle thigh and/or unexplained anemia postoperatively, the possibility that these symptoms are caused by an injury to the femoral artery must be considered.

A 31-year-old male presented with severe back pain and paraparesis. Imaging studies demonstrated an extraosseous, extradural mass without bone invasion at the T11-T12 vertebral level, located dorsal to the thecal sac. The spinal cord was compressed ventrally. The lesion was completely excised after a T11-T12 laminectomy. Histopathological examination revealed a cavernous hemangioma. The patient's symptoms improved after excision of the lesion.

In an atypical diaphyseal femoral fracture with marked anterior and lateral bowing, there are some obstacles in fixation of the fracture, such as difficulty in insertion of the intramedullary nail (IM nail) due to mismatch of the IM nail with the bow of the femur, iatrogenic fracture, nonunion due to angulation, and leg length discrepancy. We experienced a good result, which was achieved after fixation of the counterlateral curved IM nail; therefore, we report on this case with a review of the literature.

Partial or complete absence of the posterior arch of the atlas is a well-documented anomaly but a relatively rare condition. This condition is usually asymptomatic so most are diagnosed incidentally. There have been a few documented cases of congenital defects of the posterior arch of the atlas combined with atlantoaxial subluxation. We report a very rare case of congenital anomaly of the atlas combined with atlantoaxial subluxation, that can be misdiagnosed as posterior arch fracture.

Interlocked intramedullary nailing is widely accepted for treatment of closed femoral shaft fractures. An interlocking screw is inserted percutaneously, and especially the distal screw is inserted without use of a guide. Vascular complications associated with an interlocking screw in intramedullary nailing are rare. No case of delayed pseudoaneurysm caused by a distal interlocking screw has yet been reported in Korea. We present two cases of delayed pseudoaneurysm caused by a distal interlocking screw several months after intramedullary nailing.

STUDY DESIGN: Case report. OBJECTIVES: We report a very rare case of the inferior accessory ossicle of the anterior arch of the atlas misdiagnosed as anterior arch fracture. SUMMARY OF LITERATURE REVIEW: It is necessary to know the existence of inferior accessory ossicle of the anterior arch of the atlas, even though it is extremely rare. MATERIALS AND METHODS: A 29-year-old woman was referred to our emergency service unit with symptoms of neck pain and scalp laceration, after being involved in a car accident. She was diagnosed as the inferior accessory ossicle of the anterior arch of the atlas, by multiple diagnostic mordalities. RESULTS: The symptom of neck pain was relieved spontaneously, and her symptom has been relieved at her latest visit, as a follow up within 3 months. CONCLUSIONS: It is important to be aware of cervical anatomical variants because we commonly confuse it with other pathologic conditions, such as a fracture and thus, misdiagnose the condition.

PURPOSE: To evaluate the radiological and clinical results after open reduction and internal fixation with calcaneal F plate and locking calcaneal plate using lateral extensile approach in the treatment of intra-articular calcaneal fracture. MATERIALS AND METHODS: This study included 34 cases of 33 patients followed up for at least 6 months postoperatively. F plate was applied in 18 cases (Group 1), locking plate was used in 16 cases (Group 2) and compared radiological and clinical results between two groups. RESULTS: Radiollogically, the mean Bohler angle was improved from 5.5degrees preoperatively to 20.1degrees postoperatively and 18.8degrees at the last follow up in group 1 and 8.6degrees preoperatively, 21.4degrees postoperatively and 20.3degrees at last follow up in group 2. Bone union was observed in all cases and 4 cases of screw loosening were noted in Group 1 with extended fracture to anterior process. At the last follow up, both groups showed clinical results in American orthopedic foot and ankle society ankle hindfoot score, 76(77 in Sanders type II and 75 in type III) in group 1 and 72(73 in type II and 70 in type III) in group 2. CONCLUSION: F plate and locking plate showed firm fixation and satisfactory clinical results in the treatment of intra-articular calcaneal fracture. We suggest applying locking plate in cases with extended fracture to anterior process, considering screw loosenings in those who were treated with F plate fixation.

PURPOSE: This study was performed retrospectively and to compare the clinical outcomes of the surgical management using Antiglide plating and lateral plating for Danis-Weber type B isolated lateral malleolar fractures. MATERIALS AND METHODS: Between March 2004 and March 2009, 92 patients were followed up for more than 6 months after surgical treatment. 49 patients were treated with Antiglide plating, whereas the remaining 43 patients underwent lateral plating. The results of the two groups were analyzed both radiographically and clinically using Ankle scoring system. RESULTS: Both groups were comparable for age, sex distribution, time to surgery, and operation time. Bone union was noted at average of 8 weeks in all fractures. The mean ankle score was similar in both groups (94% versus 93%). CONCLUSION: Antiglide plating for Danis-Weber type B isolated lateral malleolar fracture is one of the good methods which has some advantages such as early ankle motion, ambulation and smaller operative incision.
