Résumé
Several types of soft tissue masses occur in the lower extremities. A mass associated with blood vessels is often difficult to diagnose. A 15-year-old male patient visited the author’s hospital with discomfort and edema in his right calf that had persisted for six months. A physical examination showed no palpable mass other than mild edema. Three masses were found during the ultrasound scan along the small saphenous vein. The masses had a cyst-like appearance and were filled with thrombus. In duplex ultrasound, vascular reflux was represented inside the masses. During surgery, it was suspected that vascular deformation occurred in the small saphenous vein, and simple ligation and resection treatments were performed. The patient was finally diagnosed with venous aneurysms accompanied by thrombosis based on the histology tests. The symptoms disappeared after surgery, and there were no recurrences or unusual findings at the follow-up one year later. Venous aneurysms occurring in the superficial veins of the lower extremities are rarely reported, but treatment and diagnosis are important. This paper reports a case of an aneurysm on the small saphenous vein.

Purpose@#The purpose of this study was to retrospectively evaluate the effect of ‘Blocking Kirschner Wire (K-Wire) Technique’, which has been developed to reduce protrusion of the lateral wall, in maintaining the level of reduction through clinical and radiological outcomes. @*Materials and Methods@#Twenty-two patients with displaced intra-articular calcaneal fractures who used the blocking K-wire to maintain reduction (group A) and 44 patients that did not use blocking K-wire and were paired in 1:2 ratio with those Group A patients (group B), between January 2015 and December 2017 were enrolled in the study. All surgical procedures were performed via the extended sinus tarsi approach, and internal fixation using cannulated screws, Steinmann pins and K-wires was performed. American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale and postoperative recovery of exercise ability were compared for postoperative clinical outcomes.The radiological results were compared the Böhler angle, Gissane angle, calcaneal height and width, step off of posterior calcaneal joint, and the degree of protrusion of the lateral wall. Moreover, postoperative complications in both groups were compared. @*Results@#There were no significant differences in the clinical outcomes of the two groups (p=0.924, p=0.961). The amount of Böhler angle, Gissane angle, calcaneal height and width, and step off of posterior calcaneal joint from the radiological results was not significantly different between the two groups (p=0.170, p=0.441, p=0.230, p=0.266, and p=0.400). However, the degree of protrusion of the lateral wall was 1.78 mm and 4.95 mm in group A and group B, respectively, and the difference between the two groups was significant (p=0.017). Although sural nerve entrapment and painful exostosis were more frequent in group B, they were occurred in a non-significant manner (p=0.293, p=0.655). @*Conclusion@#Most of the clinical and radiological results as well as the complications were not significantly different between the two groups. However, the degree of protrusion of the calcaneus lateral wall in group A was promising. The ‘Blocking K-Wires Technique’ established by the authors may be an effective surgical option for maintaining the reduction of the lateral wall protrusion in displaced intraarticular calcaneal fractures.

PURPOSE@#Although the number of hip arthroscopies is rapidly increasing in non-elderly patients, outcomes of this procedure in middle-aged patients are not well documented or clearly understood. The purpose of this study was to evaluate the clinical and radiological outcomes after hip arthroscopy in middle-aged patients with early osteoarthritis.@*MATERIALS AND METHODS@#This retrospective study analyzed 189 patients with early osteoarthritis of various diagnoses aged 40 years or older who underwent hip arthroscopy between January 2010 and December 2015. Clinical (e.g., modified Harris hip score [mHHS], hip outcome score-activities of daily living [HOS-ADL], visual analogue scale [VAS] for pain, range of motion) and radiological (change of Tönnis grade) outcomes were assessed at a minimum of 3-year follow-up.@*RESULTS@#The mean preoperative and final mHHS and HOS-ADL improved from 61.2 and 60.6 to 79.5 and 81.8, respectively, while the VAS pain score decreased from 6.3 to 3.2 (P<0.001). Although the mean range of internal rotation and flexion increased from 14.2 and 100.7° preoperatively to 30.4 and 110.6° at 1-year postoperatively, they decreased slightly to 27.4 and 105.4° at the final follow-up, respectively. Eight cases (4.2%) underwent revision arthroscopic surgery and three cases (1.6%) were converted to total hip arthroplasty.@*CONCLUSION@#Patients with early-stage osteoarthritis of various diagnoses achieved improved clinical outcomes. Therefore, using hip arthroscopy in middle-aged patients with early osteoarthritis, it is possible to achieve good surgical options.

PURPOSE@#This study evaluated the clinical and radiological results after reinforcement of the weakened medial joint capsule using Internal Brace (Arthrex) for treating severe hallux valgus.@*MATERIALS AND METHODS@#This study reviewed 56 cases of 50 patients that were followed-up postoperatively for at least 12 months, from September 2017 until August 2018. An extended distal chevron osteotomy combined with a distal soft-tissue release was performed by a single surgeon to treat severe hallux valgus. Internal Brace was applied in 12 cases (group A) who had weakened medial joint capsules, and capsulorrhaphy was performed in 44 cases (group B), and these two groups were compared postoperatively for the clinical and radiological results. The postoperative complications were also investigated.@*RESULTS@#No significant differences at 1-year follow-up on the Manchester-Oxford Foot Questionnaire and the patients' satisfaction scores were found between the two groups (p=0.905 and p=0.668, respectively). For the radiology, the changes of the values between before surgery and at 1-year follow-up according to the group showed no significant differences in the hallux valgus angle, intermetatarsal angle, and the hallux interphalangeal angle (p=0.986, p=0.516, p=0.754, respectively). Recurrence of hallux valgus was reported in two cases in group A, and in three cases in group B. Transfer metatarsalgia occurred in 4 cases in group B.@*CONCLUSION@#Based on these results, we recommend the capsule reinforcing technique using Internal Brace as a successful operative option for treating a weakened medial capsule in patients with severe hallux valgus.
Résumé
Stiff-person syndrome is a rare disorder, and the natural history of the syndrome has not been completely ascertained. The symptoms range from mild to severe and can progress over time: the final result can be significant disability. However, this syndrome is often misdiagnosed due to a lack of understanding of the clinical manifestations. We report the case of a patient who presented with slowly progressing gait disturbance and lower extremity pain and was later diagnosed as suffering from stiff-person syndrome. The patient experienced symptomatic improvement after the administration of benzodiazepines. No recurrence of symptoms has been reported. If the characteristic clinical features and electromyography findings of the syndrome are accurately interpreted, diagnosis of patients with abnormal muscle tension can be effectively done.

BACKGROUND: Patients with extraspinal diffuse idiopathic skeletal hyperostosis (DISH) involving the hip joint have symptoms like femoroacetabular impingement (FAI). To date, no reported study has determined the clinical outcomes of arthroscopic treatment in extraspinal DISH involving the hip joint. METHODS: A total of 421 hips with FAI that underwent arthroscopic treatment were reviewed retrospectively. We determined the extraspinal involvement of DISH with three-dimensional computed tomography (3D-CT) and simple radiography of the pelvis and hip joint. Clinical outcomes were evaluated at a minimum of 2 years postoperatively. The visual analog scale score (VAS), modified Harris hip score (MHHS), and hip outcome score–activity of daily living scale (HOS-ADL) were used, and hip range of motion (ROM) was evaluated pre- and postoperatively and at the time of the final follow-up. RESULTS: Among the 421 hips (372 patients) with FAI that underwent arthroscopic treatment, 17 hips (12 patients, 4.04%) had extraspinal DISH on the hip joints. The mean age of the patients was 51.5 years. The 3D-CT scans and simple radiographs showed extraspinal DISH on multiple points around the pelvis and hip joint. Nine of the 17 hips (seven of 12 patients) had spinal DISH. At the final follow-up, VAS, MHHS, and HOS-ADL improved significantly from 6.5, 65.3, and 66.6, respectively, to 1.2, 87.8, and 89.5, respectively, and hip flexion and internal rotation improved significantly from 97.7° and 7.9°, respectively, to 117.1° and 18.2°, respectively. CONCLUSIONS: This study has demonstrated that extraspinal DISH involving the hip joint could lead to FAI, and arthroscopic treatment could result in relief of symptoms, including pain and ROM limitation, in extraspinal DISH patients.

OBJECTIVE@#The aim of this article is to introduce the EOS imaging device, with a focus on spinal and pelvic alignment.SUMMARY OF LITERATURE REVIEW: The EOS imaging device can obtain images of spinal and pelvic alignment with almost no distortion, using a low radiation dose.@*MATERIALS AND METHODS@#We searched for studies related to the use of EOS imaging device for spinal and pelvic alignment.@*RESULTS@#The EOS is not only capable of simultaneously obtaining paired anteroposterior and lateral X-ray images with a low radiation dose, but also can reconstruct the image as if it was acquired in the patient's reference plane, limiting the distortion to the patient's thickness instead of the whole distance between the source and detector. The EOS device also has the advantage of accurately measuring the sagittal alignment of the spine and pelvis and the torsional deformity of the lower limbs, as the subject can be imaged while standing upright in a weight-bearing posture.@*CONCLUSIONS@#EOS is a new diagnostic technique that can detect spinal and pelvic alignment and deformities of the lower limbs under weight-bearing conditions with a low radiation dose.

OBJECTIVES@#We aimed to report 2 cases of coronal vertebral fracture after an OLIF procedure in non-osteoporotic patients without significant trauma, and to review the complications of OLIF.SUMMARY OF LITERATURE REVIEW: There is a growing but limited literature describing early postoperative complications after OLIF.@*MATERIALS AND METHODS@#Patient 1 was an obese woman who underwent 2-level OLIF with posterior instrumentation procedures and subsequently experienced 2-level coronal plane fractures. Patient 2 was an elderly man who underwent 3-level OLIF without posterior instrumentation and experienced 1 coronal vertebral fracture. We report vertebral body fracture as a complication of OLIF through these 2 cases.@*RESULTS@#Patient 1 was treated nonsurgically after the fractures. The fractures healed uneventfully. However, patient 2 underwent posterior instrumented fusion and had a solid bridging bone above and below the fracture. Factors potentially contributing to these fractures are discussed.@*CONCLUSIONS@#OLIF is an effective procedure for several spinal diseases. However, fracture can occur after OLIF even in non-osteoporotic patients. Factors such as intraoperative end-plate breach, subsidence, cage rolling, and inadequate posterior instrumentation could contribute to the development of fractures after oblique interbody fusion.
Résumé
BACKGROUND: After calcaneal fracture surgery, a short leg splint and cast are typically applied. However, these restrict joint exercises, which is inconvenient for patients. In addition, there is a risk of complications, such as pressure ulcers or nerve paralysis with a short leg cast. In this study, we evaluated clinical and radiological outcomes of the use of a specially designed calcaneal brace after calcaneal fracture surgery. METHODS: From among patients who underwent open reduction and internal fixation for calcaneal fracture between July 9, 2013 and May 31, 2017, 102 patients who wore a calcaneal fracture brace (group A) and 82 patients who wore a postoperative short leg cast (group B) were randomly chosen for this study. Radiological changes and clinical factors were compared between the two groups. After swelling at the surgical site decreased, a special calcaneal brace was applied to patients in group A. They were allowed to perform early weight bearing and joint motion. Patients in group B were immobilized in a short leg cast and were told to avoid weight bearing for 6 weeks. In each group, the Böhler's angle and Gissane's angle were measured and compared using postoperative and final follow-up radiographs. Pain (measured using a visual analogue scale [VAS]) and ankle joint range of motion (dorsiflexion, plantar flexion, eversion, and inversion) were measured serially until the final follow-up visit. RESULTS: There were no significant differences in the Böhler's angle or Gissane's angle between the two groups as measured postoperatively and at the final follow-up (paired t-test). Differences in the VAS pain score and eversion were also statistically nonsignificant between the two groups. However, group A had a significantly higher range of dorsiflexion (p = 0.021), plantar flexion (p = 0.012), and inversion (p = 0.045) of the ankle than group B (independent t-test). CONCLUSIONS: Application of the calcaneal fracture brace after open reduction and internal fixation of a calcaneal fracture not only maintained the fracture reduction but allowed for greater joint motion than the short leg cast. Thus, the calcaneal fracture brace can be considered an effective postoperative management option that enables early resumption of daily activities and facilitates postoperative joint motion.

An ankle sprain is a relatively common sports-related injury but a severe open ankle sprain (SOAS) is very rare. A 27-year-old female athlete was injured during running and was hospitalized because of an inversed ankle injury with an open wound. She was diagnosed initially with an open-avulsion fracture at the tip of the fibula with an anterior talofibular ligament tear. The patient was finally diagnosed with SOAS from the surgical findings and literature review. SOAS should also be considered if there is a transverse open wound at the time of an ankle injury.

PURPOSE: Good results of the cephalomedullary nails have been reported in proximal femoral fractures recently. Based on length of nails and shape of screws fixed in a femoral head for proximal fragment fixation, the proper nail length was in dispute. The purpose of this study was to evaluate the clinical and radiological results of a long cephalomedullary hip nail for the treatment of comminuted subtrochanteric femoral fractures. MATERIALS AND METHODS: Twenty-one consecutive patients with severe subtrochanteric femoral fractures who had undergone intramedullary fixation using long-PFNA II between March 2010 and March 2013 were followed-up for over 12 months. Their mean age was 64.8 years old (range, 43-85 years). Sixteen of 22 cases were high energy trauma. According to Seinsheimer's classification, 5 cases were type IV and 16 cases were type V. For radiological assessment, time to union, change of neck-shaft angle, sliding length, tip-apex distance (TAD) and leg length discrepancy (LLD) were measured. For clinical evaluation, a modified Koval index was investigated. RESULTS: Mean operation time was 96 minutes. An average decrease of neck-shaft angle was 4.5°. The average sliding length of the helical blade was 4.2 mm. Average LLD was 3.0 mm, and TAD was 23.0 mm. Mean modified Koval index score at final follow-up was 4.6 points. All the 21 subtrochanteric fractures healed uneventfully on an average of 24.2 weeks (range, 18-30 weeks). CONCLUSION: Long cephalomedullary hip nail provides excellent clinical and radiological outcomes in the comminuted subtrochanteric fracture.

As anatomical reduction of the articular surface of femoral head fractures and restoration of damaged cartilage are essential for good long-term results, many treatment options have been suggested, including fixation of the fracture using various surgical exposures and implants, as well as arthroscopic irrigation and debridement, bone marrow stimulating techniques, osteochondral allograft, autograft, and autogenous chondrocyte implantation. We report a case of osteochondral autograft harvested from its own femoral articular surface through surgical hip dislocation. The osteochondral graft was harvested from the inferior non-weight-bearing articular surface and grafted to the osteochondral defect. One year later, the clinical and radiological results were good, without the collapse of the femoral head or arthritic change. This procedure introduced in our case is considered convenient and able to lessen surgical time without morbidity of the donor site associated with the harvest.

STUDY DESIGN: A literature review on the radiologic findings of pelvic parameters for treatment of spinal deformity OBJECTIVES: This review examines sagittal spine alignment, pelvic parameters, and methods for assessing alignment, and examines the relationships among all of these parameters to understand spinal deformity. SUMMARY OF LITERATURE REVIEW: Understanding the main pelvic and sagittal spinal parameters and recognizing their correlation is imperative in the diagnosis and treatment of various spinal disorders. MATERIALS AND METHODS: Review of the literature. RESULTS: As spinal and pelvic parameters tend to have a strong correlation, it is essential to measure not only spinal parameters but also pelvic parameters in analyzing sagittal balance. Degenerative changes have the potential to greatly disrupt the normal curvature of the spine, leading to sagittal malalignment. Analysis of sagittal balance is crucial to optimizing the management of spinal diseases. Improvement in surgical outcomes may be achieved through better understanding of radiographic spino-pelvic parameters and their association with deformity. CONCLUSIONS: Understanding spinal and pelvic parameters raises awareness of the relationship among alignment and balance, the soft tissue envelope, and compensatory mechanisms, which will, in turn, provide a more comprehensive understanding of the nature of spinal deformity and the modalities with which it is treated.

PURPOSE: To report the radiographic and clinical results of 6.5 mm cancellous full threaded buttress screw or Steinmann pin fixation to maintain a reduction of calcaneal posterior facet depression fracture. MATERIALS AND METHODS: From June 2009 to June 2012, 50 consecutive cases with calcaneal joint depression fracture that underwent open reduction and screw or pin fixation were enrolled in this study. A 6.5 mm cancellous full threaded screw was inserted from the posteroinferior aspect of the calcaneal tuberosity to the posterior facet (group A) or Steinman pin was inserted from the posterosuperior aspect of the calcaneal tuberosity to the calcaneocuboidal joint (group B). Both preoperative and postoperative Bohler and Gissane angles were measured radiographically, and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale on the final follow-up were assessed. RESULTS: The mean age of patients was 44.1 years, and the mean follow-up period was 27.2 months. According to the Sanders classification, 28 cases were type II and 22 cases were type III. In Sanders type II, Bohler and Gissane angles improved significantly from 10.1degrees and 126.2degrees preoperatively to 27.2degrees and 117.1degrees, respectively, in the immediate postoperative radiograph, and at the final follow-up, 26.6degrees and 118.6degrees, respectively. In Sanders type III, Bohler and Gissane angles improved significantly from 5.0degrees and 129.8degrees to 29.9degrees and 119.3degrees, respectively, in the immediate postoperative radiograph, and 26.9degrees and 120.2degrees at the final follow-up. All cases achieved bony union, and the average period until complete union was 13.3 weeks. AOFAS ankle-hindfoot scale was 82.6 in Sanders type II and 77.3 in Sanders type III at the final follow-up. CONCLUSION: A 6.5 mm cancellous full threaded buttress screw or Steinman pin fixation is a noninvasive treatment method with a merit of being able to maintain the bearing capacity of the posterior facet comparable to plate fixation.

PURPOSE: The purpose of this study is to compare and analyze the clinical results according to the complications occurring after laminoplasty for cervical myelopathy patients. MATERIALS AND METHODS: Among patients diagnosed as cervical myelopathy, 152 cases in which patients underwent cervical laminoplasty from March 2006 to March 2011 from Chungnam National University Hospital and had follow-up for at least two years were selected for the study, and the mean follow-up period was 39.7 months. The cases were divided into two groups; cases that underwent plate fixation for hinge fracture during cervical laminoplasty or showed postoperative spontaneous interlamina fusion were included in group A and cases that did not show such complications were included in group B. Clinical results were measured using visual analogue scale (VAS) score and Neck Disability Index (NDI) preoperatively, postoperatively, and on the final follow-up. RESULTS: Among 152 cases, 31 cases were included in group A and 121 cases in group B. Group A consisted of 11 cases of fixation due to intraoperative hinge fracture and 20 cases of postoperative spontaneous interlamina fusion. Mean preoperative VAS score was 7.52 in group A and 7.26 in group B, and mean postoperative VAS score was 2.87 in group A and 3.03 in group B. Mean NDI improved from 74.32% preoperatively to 43.84% postoperatively in group A and 75.74% preoperatively to 45.36% postoperatively in group B. In both groups, on postoperative follow-up, no significant difference of VAS score and NDI was found and both showed improvement compared to before surgery. CONCLUSION: The clinical results of cases that underwent plate fixation for hinge fracture that occurred during cervical laminoplasty and postoperative spontaneous interlamina fusion showed no significant difference compared to cases that did not show any complications.

PURPOSE: To analyze the arthroscopic findings and treatment results of patients with a limitation of hip motion caused by early degenerative osteoarthritis. MATERIALS AND METHODS: Retrospective analysis was performed on 13 patients who underwent arthroscopic treatment from May 2009 to March 2010, among patients with a limitation of hip motion and femoroacetabular impingement symptoms by early degenerative osteoarthritis. Head-neck offset, anteversion, and a change in the alpha angle was compared. At the final follow up, the VAS (Visual analogue scale), modified Harris hip score, and range of motion were compared. RESULTS: The arthroscopic findings showed diffused synovitis in all 13 cases. Among them, 9 cases were accompanied with a labral tear, and 2 cases showed a labral deformity. The VAS decreased from 7.5 preoperatively to 1.8 postoperatively and the modified Harris hip score improved from 49.3(35-60) before surgery to 90.1(85-95) after surgery. Each flexion and internal rotation improved significantly (P<0.05) from 95.2degrees (60-120degrees) to 127.7degrees (110-140degrees) and 4.6degrees (-5-25degrees) to 25.4degrees (15-30degrees), respectively. CONCLUSION: This study shows that the arthroscopic treatment of femoroacetabular impingement with a limitation of the range of motion by early degenerative arthritis can be expected with an improvement in flexion and internal rotation of the hip.
