Late Occlusion of the Femoral Artery Occurred after the Operation for a Femoral Shaft Fracture / 대한정형외과학회잡지

Once ischemic necrosis occurs in the tissue below an injury site after trauma, a vascular injury is suspected first. On the other hand, it is not common for a blood vessel to become obstructed after a delay of a few days after the initial trauma. The authors experienced a case where the blood flow was maintained at the time of a femoral fracture injury and immediately after surgery, but the femoral artery was occluded later. On the 5th day after surgery, ischemic necrosis of the lower limb was confirmed and treated. This case is reported with a review of the relevant literature.

Concurrent Posterolateral Corner Injury Associated with a Schatzker Type 2 Tibial Plateau Fracture: A Case Report

Isolated posterolateral corner (PLC) injury associated with a Schatzker type 2 fracture is a very rare combination of injuries. A male who was driving a motor vehicle was injured after a collision accident. The plain radiographs and computed tomography scans of the knee showed a Schatzker type 2 fracture of the tibial plateau, mostly in the anterolateral portion of tibial plateau, and an avulsion fragment on the fibular tip. Magnetic resonance imaging showed no injury to cruciate ligaments, medial collateral ligament, or any meniscal injury. We performed an open reduction operation and internal fixation for treating the fracture. Six months later, he complained of instability. At 11 months later after initial operation, we performed the second operation for stabilizing the PLC. We present here a rare case of an isolated PLC injury associated with a Schatzker type 2 fracture. We discuss the mechanism of injury and review similar cases.

Meniscal Extrusions on a Non-Traumatic and Young Knee: Magnetic Resonance Imaging Study / 대한정형외과학회잡지

PURPOSE: The aim of this study was to assess the size and extrusion of the meniscus in young and non-traumatic knees, especially in Korean males. MATERIALS AND METHODS: The participants (n=91 knees, 77 patients) were consecutive patients observed at an orthopedic outpatient clinic who had another problem unrelated to the knee joint. The patients were excluded from the study if they had a history of trauma and pain on the knee joint. The patients received a magnetic resonance imaging (MRI) scan on the knee joint. The size, extrusion, and extrusion ratio of the meniscus on an MRI scan were evaluated. RESULTS: The mean age of the participants was 21.6±1.1 years (range, 19–24 years). The mean size of the medial meniscus on the coronal plane was 9.0±1.1 mm (range, 7.1–11.9 mm). The extent of extrusion on the coronal plane was 2.0±1.0 mm (range, 0–4.4 mm). The extrusion ratio (extruded size/total size×100) of the medial meniscus on the coronal plane was 22.7%±11.5% (range, 0%–53.7%). The extent of extrusion on the sagittal plane was 1.6±1.1 mm (range, 0–4.0 mm). The extrusion ratio (extruded size/total×100) of the medial meniscus on the sagittal plane was 18.0%±11.9% (range, 0%–40.7%). The incidence of medial meniscal extrusion on the coronal and sagittal plane are 92.3% and 80.2%, respectively. The mean size of lateral meniscus on the coronal plane was 11.1±3.4 mm (range, 7.3–22.9 mm). The extent of extrusion on the sagittal plane was 0.5±0.7 mm (range, 0–2.5 mm). The extrusion ratio of the lateral meniscus on the sagittal plane was 4.0%±6.7% (range, 0%–26.3%). The incidence of lateral meniscal extrusion on the coronal plane was 34.1%. No extrusion of the lateral meniscus was observed on the sagittal plane. CONCLUSION: In young and non-traumatic knees, the extrusion of meniscus was common, especially medial meniscus than lateral meniscus.

The Different Treatment Methods for Segmental Fractures of the Clavicle: Cases Report

Segmental fractures of the clavicle are very rare. Therefore, to date, there has not been a clear, standardized method of management of segmental clavicle fractures. Herein, two patients with a segmental fracture are described: One patient was treated conservatively, while another patient was treated operatively. Both patients showed excellent results. We discuss the various management options with a literature review.

Avulsion Rupture of Flexor Digitorum Profundus in Zone 1, Diagnosed in Early Stage

Avulsion injury of the flexor digitorum profundus (FDP) tendon from the distal phalanx is considered as a rare injury. We report a patient who sustained a FDP tendon rupture insertion on her fifth finger as a result of a closed, hyperextension with no accompanying laceration or predisposing pathologic condition. Preoperative ultrasonography showed complete rupture of FDP and the gap between the tendon ends. According to the classification by Leddy and Pacter, this case is type II. The reconstruction of flexor tendon using pull-out suture and tie-over button. We are reporting a case with brief review of literatures.

Treatment of Fractures of the Distal Radius Using Variable-Angle Volar Locking Plate

PURPOSE: The purpose of this study is to evaluate outcome of variable-angle volar locking plate for treatment of distal radius fractures. MATERIALS AND METHODS: We retrospectively analyzed the results in 45 cases treated by variable-angle volar locking plate. We evaluated the clinical results according to the Mayo wrist performance scoring system and radiographic results. RESULTS: All cases had bony union. The mean Mayo wrist performance scoring system was 84.8. Between preoperative and immediate postoperative radiographic measurement, the mean radial length improved from 8.4 to 11.8 mm, radial inclination from 14.2degrees to 22.4degrees, volar tilt from -4.5degrees to 9.6degrees, and intraarticular step-off from 1.8 to 0.3 mm (p0.05). All cases showed bone union with no evidence of malunion, nonunion, or metal failure. CONCLUSION: Treatment of distal radius fractures using variable angle volar locking plate showed satisfactory outcomes. It is a good option to obtain stable fixation without significant loss of reduction.

Treatment of Olecranon Fractures with Proximal Ulna Comminution Using Locking Compression Plates

PURPOSE: The purpose of this study is to evaluate the clinical results of locking compression plate (LCP) fixation for olecranon fractures with proximal ulna comminution. MATERIALS AND METHODS: We review 10 cases of olecranon fractures with proximal ulna comminution treated with LCPs from August 2011 to August 2013. Follow-up period was from 12 months to 18 months. Mean age was 63.1 years (35-84 years). According to the Mayo classification, there were eight type IIB, and two type IIIB fractures. We used Mayo classification. Clinical evaluation was performed based on radiographic union of olecranon and measurements of range of motion at last follow-up. Disability of the arm, shoulder and hand (DASH) score and Mayo elbow performance score (MEPS) were used for evaluation of functional recovery. RESULTS: All patients had bone union. According to the MEPS, nine of ten patients had a good or excellent outcome. The mean DASH score was 18.6. All cases started postoperative range of motion (ROM) within 14 days. Elbow ROM was more than 110degrees in all cases except one. Mean radiological bony union time was 4.2 months (2.5-6.0 months) postoperatively. Complication was hardware irritation in three patients. CONCLUSION: Internal fixation using LCP for olecranon fractures with proximal ulna comminution can be a good treatment option which obtains good clinical results and enables early ROM.

Comparative Study of Intertrochanteric Fracture Treated with the Proximal Femoral Nail Anti-Rotation and the Third Generation of Gamma Nail

PURPOSE: To compare the result between the third generation gamma nail (gamma 3 nail) and proximal femoral nail anti-rotation (PFNA) in the treatment of unstable intertrochanteric fractures. MATERIALS AND METHODS: Between March 2009 and June 2011, 47 consecutive patients with unstable intertrochanteric femoral fractures were treated with gamma 3 nail or PFNA. We reviewed 24 cases of gamma 3 nail and 23 cases of PFNA. Retrospectively, we evaluated the mean operation time, amount of bleeding, average union period, reduction status, change of neck shaft angle, Tip-apex distance, Cleveland index, sliding of lag screw and complication on set of telephone interview and outpatient. We also evaluated the postoperative capability of function and mobility, using 'Modified Koval index'. RESULTS: There were no significant differences between the groups, which were treated with gamma 3 nail and PFNA. In addition, they did not show statistical difference. We experienced 2 cases of complication (gamma 3 nail 1 case, PFNA 1 case), which were cut-out of the femoral head. CONCLUSION: The gamma 3 nail and PFNA were seen with good results in the treatment of unstable intertrochanteric fracture.

Intra-articular Benign Fibrous Histiocytoma of the Knee: A Case Report / 대한골관절종양학회지

Benign fibrous hitiocytoma of the infrapatella fat pad is very rare. It has usually do not induced a pain or a symptom because it was located deep tissue. So it was very difficult to be diagnosed. We experienced a case of deep benign fibrous histiocytoma in a 53-year-old woman. It was diagnosed by MRI. Diagnostic arthroscopic procedure was performed and the lesion was completely resected by open excision. We report a rare case of benign fibrous hitiocytoma presenting as an intra-articular tumor in the joint causing pain and limitation of movement.

Intratendinous Ganglion in the Extensor Tendon of the Great Toe: A Case Report / 대한정형외과학회잡지

A ganglion is the most common soft tissue tumor. But an intratendinous ganglion is a rare lesion of unknown etiology but with a natural history that originates within the tendon. A 52 year-old man complained of a palpable, non-tender mass in the dorsum of the right foot. We present a case of an intratendinous ganglion that developed in the extensor hallucis brevis tendon and which was treated successfully by excision.

Lateral Plate Fixation of Distal Tibial Metaphyseal Fracture Using Minimally Invasive Plate Osteosynthesis Technique

PURPOSE: To evaluate the efficiency of lateral plate fixation using minimally invasive plate osteosynthesis (MIPO) technique as a treatment of distal tibial metaphyseal fracture. MATERIALS AND METHODS: Among the patient who were treated from March, 2002 to September, 2004, the cases of twenty patients with distal tibial metaphyseal fracture treated by lateral plate fixation using MIPO technique who were able to be followed up for at least one-year period were reviewed in this study. According to AO/OTA classification, five were type A1, twelve cases were type A2 and other three cases were type A3, and among them two cases were open fracture type I according to the Gustillo-Anderson classification. Radiologic studies and clinical assessment described by Daniel et al and complication following the treatment were evaluated. RESULTS: At a mean of 16.4 weeks (range 11 to 23), all fractures united without secondary procedures. According to clinical assessment, all cases had good and excellent result, and there were no complications. CONCLUSION: The lateral plate fixation using MIPO technique of distal tibial metaphyseal fracture is an efficient method of treatment with high functional recovery rate which minimize soft tissue damage, decreases the risk of infection and incidence of nonunion at the same time as the classic MIPO technique does, and it is a useful alternative method when there is a anteromedial soft tissue damage.

Two Stage Reimplantation in Infected Total Knee Arthroplasty Using an Articulating Antibiotics Impregnated Cement Spacer: Surgical Technique

PURPOSE: To evaluate the clinical result of two stage reimplantation of infected total knee arthroplasties, using an antibiotics impregnated articulating cement spacer. MATERIALS AND METHODS: Out of total 7 cases with infected total knee arthroplasties, 4 cases treated with two stage reimplantation, using an antibiotics impregnated articulating cement spacer were included in this study. After the treatment of infected total knee arthroplasties, the treatment of infection was evaluated by physical examination, radiologic studies, and hematologic studies. The results were evaluated using the Hospital for Special Surgery Knee Score (HSS). RESULTS: As results, 4 infected knee cases treated with two stage reimplantation did not have reinfection at the time of the follow up, and physical, laboratory, and radiologic studies were all within normal range. The range of motion of the reimplanted knees were from -5degrees in extension to 130 degrees in flexion, with an average of 117 degrees. The average score of the Hospital for Special Surgery Knee Score was 87. CONCLUSION: In conclusion, two stage arthroplasties, using antibiotics impregnated articulating cement spacer was an effective therapy not only for the treatment of the infection after the total knee arthroplasty but also effectiveness for recovery of the knee function.

Treatment of Fractures of the Lateral Malleolus using Locking Compression Plate / 대한족부족관절학회지

PURPOSE: The purpose of this study was to investigate usefulness of locking compression plate (LCP) as an open reduction technique by evaluating clinical results obtained from the patients with lateral malleolar fracture treated by internal fixation using LCP after open reduction. MATERIALS AND METHODS: Among the patients with lateral malleolar fracture, the 28 patients who were treated by internal fixation using Locking compression plate after an open reduction and were able to be followed up for more than 6 months were included in this study. Final postoperative evaluation was done based on the Meyer's clinical and radiologic evaluation system. RESULTS: All cases achieved anatomical reduction and fixation of the reduction postoperatively. 28 minutes were taken meaningly from the incision to the fixation of LCP plate after the anatomical reduction. Everage bony union time was 8.2 weaks, and the result was excellent in 23 cases (82%), good in 5 cases (17%) and poor result was abscent according to the criteria of Meyer et al. One case of post traumatic arthritis and one case of superficial infection on the operation site were found, but non-union, delayed union and malunion were not occurred. CONCLUSION: The internal fixation after open reduction using LCP is an effective treatment method in treating lateral malleolar fracture of the ankle since it offers advantages including easy application and a greater stability due to its capability of maintaining exact anatomical reduction even though the screw does not penetrate the medial cortex of fibular to add the stability and rigidity of the fixation.

Treatment of Fractures of the Distal Radius using Locking Compression Plate

PURPOSE: To evaluate the usefulness of locking compression plate (LCP) and volar plating through anterior approach for distal radius fracture. MATERIALS AND METHODS: We retrospectively analysed that 15 distal radius fracture, which would not be reduced by closed reduction or too comminuated to maintain reduction or articular surface inconguency, were treated by open reduction through anterior approach and volar plating using LCP. The results were evaluated by preoperative and postoperative radiographs. Functional results were analysed using the Modified Mayo Wrist Scoring System. RESULTS: All cases achieved anatomical articular surface reduction postoperatively. In terms of radiologic analysis, mean radial length (9.0 mm vs. 11.8 mm), radial inclination (14.7degrees vs. 20.9degrees ), volar tilt (-6.3degrees vs. 8.3degrees ) and articular step-off (1.4 mm vs. 0.3 mm) were improved. The average Modified Wrist Score was 89. Nonunion or malunion was not occurred. CONCLUSION: Open reduction through anterior approach and volar plating using LCP is a useful method that provides excellent results with few complications in the treatment of fracture of the distal radius.

Intramedullary Fixation of Clavicle Fracture Percutaneously Reduced By Towel Clip

PURPOSE: To investigate the utility of surgical treatment of clavicle shaft fracture using a percutaneous towel clip reduction and intramedullary fixation. MATERIALS AND METHODS: This study was conducted for total 16 cases of patients who had no neurovascular injury and a few comminuted bone fragment among patients with clavicle shaft fracture from January 2002 to July 2003. The method of operation was percutaneous towel clip reduction and intramedullary fixation. The clinical and radiological results were evaluated. RESULTS: Radiologically, 15 cases showed bone unions and the average time was 9.1 weeks. According to Kang's criteria clinically, there were 14 cases which were more than an excellence. One case substituted open reduction and nailing fixation due to a medial migration of K-wire and re- displacement of fracture even in 1 week. However, there wasn't any other major complication. CONCLUSION: Due to its having no additional injury to soft tissues, no scar formations, and its short operation time, percutaneous towel clip reduction and intramedullary fixation will be very useful as one of the treatments of clavicular shaft fracture if it follows correct surgical indications.

Autogenous Bone Graft with Bone peg for the Medial Tibial Bone Defect in Total Knee Arthroplasty

PURPOSE: The aim of this study is to report the usability of autogenous bone graft with bone peg in total knee arthroplasty in the patients with tibial medial bone defect from osteoarthritis due to severe varus deformity. MATERIALS AND METHODS: From July 1998 to December 2000, fifteen total knee arthroplasties with autogenous bone graft were performed for the medial tibial bone defects. The proximal tibia was resected and then bone pegs which were prepared from resected portion of distal femur and proximal tibia were inserted into the defect site with the shape of peg in the anterior posterior view using press fitting method. Instead of applying screw or K-wire, we performed press-fitting method for early stability. For attaining the stability, we preserved the sclerotic rim and designed precisely the bony defect site. We reviewed the result using the HSS Knee Rating Scale and observed the radiologic change. RESULTS: In HSS Knee Rating Scale review, 52.4 of preoperative score was improved to 84.7 at postoperative 1 year. Tibio-femoral angle , the average 17.8 degrees of varus was improved to the average 5.8 degrees of valgus at 1 year postoperatively. The average union period was 5 months, and there was no evidence of the displacement of grafted bone and loosening of the inserted implants. CONCLUSION: The method of autogenous bone graft applied with bone peg could be supposed as the stable fixation method without using screws or K-wires.
