Two-Stage Operation Over a Period of 7 Years for a Patient with Macrodactyly: A Case Report / 대한족부족관절학회지

Macrodactyly of the toe is a rare congenital anomaly characterized by the overgrowth of a digit/digits in the foot and is one of the most difficult conditions to treat. Since the condition alters functionality and appearance, the treatment goal is to restore function and cosmetically enhance the appearance. Various surgical techniques are used for toe macrodactyly, including amputation, debulking, and epiphysiodesis. Herein, we present a case of a six-year-old patient with a second toe macrodactyly who was successfully treated with a twostage operation over a seven-year period. We initially performed an ostectomy of the middle phalanx with a fusion of the proximal and distal phalanges and then performed a soft tissue debulking procedure.

Operative Positioning Technique for an Intertrochanteric Fracture in a Patient with an Ipsilateral Above-the-Knee Amputation - Technical Note -

A 45-year-old man with a remote history of a left above-the-knee amputation presented to the emergency department with left hip pain after a mechanical fall. This case was an operative challenge because commonly used intraoperative traction methods could not be applied to a patient with an above-the-knee amputation. We describe a rarely utilized surgical technique of applying traction to an amputated extremity via a Steinmann pin during closed reduction and internal fixation of an intertrochanteric fracture.

Outcome of Conservative Treatment of the Zone I, II 5th Metatarsal Base Fracture under Early Weight-Bearing / 대한정형외과학회잡지

Purpose@#To determine how the location, displacement, intra-articular involvement, comminution of a 5th metatarsal base fracture affect results of early weight-bearing treatment. @*Materials and Methods@#From January 2013 to July 2017, 34 cases of 34 patients diagnosed with a fracture of the zone I and II 5th metatarsal base were enrolled. The mean follow-up period was 13 months (6–15 months). One patient was excluded as a refracture during the follow-up period, and 33 patients underwent conservative treatment. Anteroposterior, lateral, and simple oblique radiography and computed tomography of the foot were performed to evaluate the location and displacement of the fracture, the degree of joint involvement, and comminution. In all 33 patients, a short leg cast or boot brace was selected immediately after the injury, tolerable weight bearing was allowed. If the pain disappeared, full weight bearing was performed after wearing a plain shoe or postoperative shoe. As a clinical result, the American Orthopedic Foot and Ankle Society (AOFAS) score was evaluated at the final follow-up. During outpatient follow-up, a simple radiograph of the foot was taken to confirm the time of radiological bone union and return to work. @*Results@#Nine males and 24 females, with an average age of 48.7 years, were enrolled in the study. Twenty-four patients had zone I fractures, and nine patients had zone II fractures. Twenty-two out of 33 patients had a fracture displacement of 2 mm or more. Nine and five patients had joint involvement and comminution, respectively. There was a statistically significant return to work from zone I to zone II. The AOFAS score was excellent at the final follow-up and there was no significant difference. When classifying and comparing the degree of fracture displacement, joint involvement, and comminution, there were no significant differences in the radiological union time and return to work. In all cases, satisfactory results were obtained at the final follow-up. @*Conclusion@#Satisfactory clinical results can be obtained by allowing early weight-bearing regardless of the fracture location, displacement, joint involvement, or comminution in zone I and II 5th metatarsal base fractures.

Three-Dimensional Analysis of the Morphological Features in the Femur of Atypical Fracture and Practical Implications of Intramedullary Nailing

Purpose@#This study analyzed the morphological features of the contralateral femur without an atypical fracture by constructing a three-dimensional model with an actual size medullary canal. @*Materials and Methods@#Lateral and anterior bowing of the shaft were measured for 21 models, and the shape of the medullary canal was analyzed. To eliminate the projection error, the anteroposterior (AP) femur was rotated internally to the extent that the centerline of the head and neck, which is the ideal position of cephalomedullary nail screw, was neutral, and the lateral femur matched the medial and lateral condyle exactly. @*Results@#The lateral bowing and anterior bowing was an average of 5.5° (range, 2.8°-10.7°; standard deviation [SD], 2.4°) and 13.1° (range, 6.2°-21.4°; SD, 3.2°), respectively. In the area where lateral bowing increased, the lateral cortex became thicker, and the medullary canal was straightened. On the lateral femur, the anterior angle was increased significantly, and the diameter of curvature averaged 1,370.2 mm (range, 896-1,996 mm; SD, 249.5 mm). @*Conclusion@#Even if the anterolateral bowing increases in the atypical femur, the medullary canal tends to be straightened in the AP direction. So, it might be considered as a reference to the modification of an intramedullary nail to increase the conformity.

Efficacy of Temporal Fixation Using Threaded Trans-Calcaneal Pin in Patients with Ankle Fracture-Dislocation or Tibia Pilon Fractures / 대한족부족관절학회지

Purpose@#Ankle fractures with dislocations and pilon fractures at the distal tibia are usually associated with soft tissue damage caused by high-energy damage. Recently, a two-stage operation to perform internal fixation after the application of external fixation devices for stabilizing soft tissues has been accepted as the treatment of choice. This paper reports the clinical result of these injuries treated with threaded trans-calcaneal pin external fixation devices. @*Materials and Methods@#Thirty-three patients diagnosed with ankle fractures with dislocations or tibial pilon fractures without open wounds. They underwent surgical treatment with threaded trans-calcaneal pin external fixation from January 2008 to February were enrolled in this study. This study evaluated the visual analogue scale (VAS), foot function index (FFI), and Olerud & Molander score as well as whether complications occurred. @*Results@#The average VAS showed a meaningful decrease (p<0.001) from 7.4 before surgery to 2.6 after application of the external fixation device, and 1.4 at 12 months after surgery. The FFI also decreased significantly from 84.3 preoperatively to 20.3 at 12 months postoperatively (p<0.001). The Olerud & Molander score averaged 71.4 points, showing good clinical results. Complete bone union was observed in all patients. One patient each underwent debridement due to wound necrosis and infection in the pin insertion site. At the final follow-up, seven patients had posttraumatic ankle joint arthritis, according to a radiological examination. @*Conclusion@#Manual reduction and external fixation using a threaded trans-calcaneal pin is a suitable surgical technique that is easy to perform and shows good clinical outcomes in stabilizing soft tissue damage in fractures and dislocations of ankle fracture or tibia pilon fractures in foot and ankle injury.

Ulnar Insufficiency Fractures in Patients on Prolonged Bisphosphonate Therapy: A Case Report

Atypical fractures associated with prolonged bisphosphonate (BP) therapy rarely occur outside the femur, and the diagnostic criteria, appropriate treatment principles, and fixation methods for atypical ulnar fractures have not been established. The authors experienced the use of internal fixation with a metal plate and a new internal fixation method with an intramedullary nail in the treatment of an atypical ulnar fracture in a patient who had been on BP therapy for 10 to 20 years. This paper reports findings along with a review of the relevant literature.

Difference of Critical Shoulder Angle (CSA) According to Minimal Rotation: Can Minimal Rotation of the Scapula Be Allowed in the Evaluation of CSA?

BACKGROUND: Minimal rotation of the scapula may affect the measurement of critical shoulder angle (CSA). We investigated the difference in the CSA measured in minimal rotation between the patients with rotator cuff tear and those without non-rotator cuff tear and the CSA measurement error by comparing with computed tomography (CT). METHODS: We retrospectively reviewed patients with full-thickness rotator cuff tear and whose X-ray views correspond to Suter-Henninger classification type A1 and C1. The CSA values between the normal control group (without rotator cuff tear) and the rotator cuff tear group were compared according to A1 type and C1 type. In the rotator cuff tear group, we compared the CSA values measured by using X-ray and CT. RESULTS: A total of 238 patients (rotator cuff tear group, 139 patients; normal cuff group, 99 patients) were included in this study. The mean CSA of the rotator cuff tear group was 33.4° ± 3.5°, and that of the normal cuff group was 32.6° ± 3.9° (p = 0.085). On comparison of the CSA according to the Suter-Henninger classification type, the CSA values on the A1 type view and C1 type view were 32.7° ± 3.5° and 33.7° ± 3.5°, respectively, in the rotator cuff tear group and 30.5° ± 3.1° and 33.1 ± 3.9°, respectively, in the normal cuff group (p = 0.024 and p = 0.216, respectively). The mean CSA was 32.5° ± 3.1° in CT and 33.3° ± 3.2° in X-ray (p = 0.184). On comparison of the CSA according to the Suter-Henninger classification type, the CSA values on the A1 type view and C1 type view were 32.6° ± 3.6° and 32.5° ± 2.4°, respectively, in CT and 32.5° ± 3.5° and 34.2° ± 2.6°, respectively, in X-ray (p = 0.905 and p = 0.017, respectively). CONCLUSIONS: The X-ray view corresponding to Suter-Henninger classification type A1 or CT-reconstructed image can be used to reduce the measurement error and obtain reliable CSA values. The CSA measured on the X-ray view corresponding to Suter-Henninger classification type A1 may be related with rotator cuff tear.

Femur Neck Fracture in a Young Marfan Syndrome Patient / 대한고관절학회지

Marfan syndrome is an autosomal dominant and could decrease bone mineral density. So patients with Marfan syndrome could vulnerable to trauma in old ages. We present the first report, to the best of our knowledge, of a rare fracture of the femoral neck with a minor traumatic history in a juvenile Marfan syndrome patient whose physis is still open. Although the patient is young, her bone mineral density was low and the geometry of femur is changed like old ages. The femur neck fracture in children is very rare and only caused by high energy trauma, we concluded that the Marfan syndrome makes the bone weaker in young age and preventative medications to avoid fractures in younger Marfan syndrome patients are necessary in early ages.

Pathologic Fracture of the Femur in Brown Tumor Induced in Parathyroid Carcinoma: A Case Report / 대한고관절학회지

Brown tumor refers to a change of skeletones that develops as a complication of hyperparathyroidism. As osteoclast is activated to stimulate reabsorption and fibrosis of bone, it causes a cystic change of the bone. Parathyroid carcinoma is being reported as a tumor that induces primary hyperparathyroidism. It causes excessive secretion of the parathyroid hormone and increases the blood parathyroid hormone and calcium. Bone deformation due to brown tumor is known to be naturally recovered through the treatment for hyperparathyroidism. However, there is no clearly defined treatment for lesions that can induce pathological fractures developing in lower extremities. We experienced a case where brown tumor developed in the proximal femur of a 57-year-old female patient due to parathyroid carcinoma. In this case, spontaneous fracture occurred without any trauma, and it was cured by performing intramedullary nailing fixation and parathyroidectomy. We report the treatment results along with a literature review.

Trapezoid Stress Fracture in a Weight Lifter / 대한정형외과학회잡지

Trapezoid fracture is a rare condition and especially, isolated trapezoid fracture is most rare condition of carpal bone fracture. And principle of treatment has not yet been established. Most of trapezoid fractures can be treated using cast but displaced fracture or fracture combined with other carpal bone fractures may require operative treatment. There have been reports about case of conservative treatment in trapezoid stress fracture but no report about case of operative management. We treated a trapezoid stress fracture in a weight lifting athlete by operative treatment and report the results with literature review.

Compartment Syndrome of the Gluteus Medius Occurred without Bleeding or Trauma: A Case Report / 대한고관절학회지

Compartment syndrome is an ischemic change resulting from an increase in compartment pressure. Initially, patients present with direct tenderness and swelling, and the weak circulation secondary to compartment syndrome can eventually lead to motor and sensory impairment. If the increase in pressure results in neurological impairment, emergency intervention is required to decompress the compartment. Typically, compartment syndrome develops on forearms or lower legs. The gluteal compartment is rarely the location of compartment syndrome and only a few cases have been presented in the literature with trauma or hematoma. We have treated a patient with gluteal compartment syndrome who presented with no history of trauma or hemorrhage and present that case report here.

Changes in Dynamic Pedobarography after Extensive Plantarmedial Release for Paralytic Pes Cavovarus

PURPOSE: Plantarmedial release and first ray extension osteotomy are often combined to treat paralytic cavovarus foot deformity. The purpose of this study is to evaluate the effect of additional first ray extension osteotomy in terms of dynamic pedobarography. MATERIALS AND METHODS: We reviewed findings of pre- and postoperative plain radiography and dynamic pedobarography for 25 patients in whom the flexibility of the hindfoot was confirmed by the Coleman block test. The results of treatment by extensive plantar medial release with first ray osteotomy (group I) were compared with the results of treatment by extensive plantar medial release alone (group II). RESULTS: Plain radiographs obtained pre- and postoperatively showed no statistically significant improvement in each group. Only in group I, peak forces at the 1st metatarsal head, 2nd metatarsal head and medial calcaneus were increased after operation. CONCLUSION: In paralytic hindfoot flexible cavovarus, extensive plantarmedial release with first ray osteotomy improve foot pressure distribution more than extensive plantarmedial release alone.

Comparison of the Efficacy of Urine Cytology, Nuclear Matrix Protein 22 (NMP22), and Fluorescence in Situ Hybridization (FISH) for the Diagnosis of Bladder Cancer / 대한비뇨기과학회지

PURPOSE: We compared the efficacy of urine cytology, nuclear matrix protein 22 (NMP22), and fluorescence in situ hybridization (FISH) for the detection of bladder cancer. MATERIALS AND METHODS: Washing urine samples from 156 patients were evaluated for the detection of bladder cancer. Patients were divided into 3 groups. Group 1 was 106 patients with bladder cancer, group 2 was 30 patients with benign prostatic hyperplasia who underwent transurethral resection of the prostate without bladder cancer, and group 3 had gross hematuria without bladder cancer. The sensitivity and specificity of cytology, NMP22, and FISH were compared. NMP22 positivity was defined as > or =10U/ml. FISH was done with the UroVysion(R) system and FISH positivity was defined as > or =2 abnormal urothelial cells with an abnormal signal from any out of 4 probes. RESULTS: The overall sensitivity of urine cytology, NMP22, and FISH was 60.4%, 75.5%, and 84.9%, respectively (p<0.001). The overall specificity of cytology, NMP22, and FISH was 96.7%, 83.3%, and 93.3%, respectively (p=0.168). In group 3, the false-positive rates of cytology, NMP22, and FISH were 20.0%, 55.0%, and 10.0%, respectively. In these patients with gross hematuria, the false-positive rate with NMP22 was significantly higher than with cytology or FISH (p=0.004). The sensitivity of cytology, NMP22, and FISH in low-grade bladder cancer patients was 25.9%, 51.9%, and 77.8%, respectively, and that in pTa-1 bladder cancer patients was 40.6%, 65.6%, and 78.1%, respectively. In low-grade or in pTa-1 patients, the sensitivity of the three diagnostic tools was significantly different (low grade; p<0.001, pTa-1; p<0.001). CONCLUSIONS: FISH is more sensitive in low-grade bladder cancer than is urine cytology and can be used as a diagnostic tool for the detection of primary and recurrent bladder cancer. NMP22 was affected by gross hematuria and thus has limitations for screening of bladder cancer. However, it can be used to follow-up bladder cancer.

Treatment of Upper and Mid Ureter Stones: Comparison of Semirigid Ureteroscopic Lithotripsy with Holmium: YAG Laser and Shock Wave Lithotripsy / 대한비뇨기과학회지

PURPOSE: To compare the success rates, complications and cost effectiveness of extracorporeal shock wave lithotripsy (ESWL) and ureteroscopic lithotripsy (URS) using a Holmium: YAG laser to establish the more effective treatment for upper and mid ureter stones. MATERIALS AND METHODS: This retrospective study included 83 and 286 patients treated with URS and ESWL, respectively, for upper and mid ureter stones. URS was performed with a 7.5Fr semi-rigid ureterorenoscope and Holmium: YAG laser. ESWL was performed with Stonelith V.5 (PCK, Turkey). The stone sizes, success rates, postoperative complications and cost effectiveness were analyzed for each group. RESULTS: The overall success rates of the URS and ESWL were 97.6 and 82.5%, respectively. Success rates of URS were 98.4 and 95.2% when the stones were smaller and larger than 10mm, respectively. In the ESWL group, the success rates after the third session were 86.3 and 65.4% with stones smaller and larger than 10mm, respectively. The complication rates associated with URS and ESWL were 6 and 4.2%, respectively. The average cost of URS was lower than that of ESWL. CONCLISIONS: In our study, URS with Holmium: YAG laser was more efficacious than ESWL. Considering both the success rate and cost effectiveness, URS should remain the recommended first-line treatment for upper and mid ureter stones.
