Résumé
Background@#The use of electric scooters (e-scooters) continues to increase as a simple, inexpensive means of transport, resulting in a sharp increase in the incidence of scooter-related accidents. No study to date has closely examined the injury extent to the lower leg, joints, and extremities from e-scooter-related accidents. Here, we investigated the epidemiology and injury patterns of such accidents, focusing on injuries to the ankle and foot. @*Methods@#Based on data from a single tertiary hospital’s database, the demographics of 563 patients with scooter-associated injuries were analyzed retrospectively. Among the patients, 229 patients who were injured by e-scooter riding were further investigated. Based on the data, the general demographics of whole scooter-associated injuries and the injury characteristics and fracture cases of the lower leg, ankle, and foot were analyzed. @*Results@#During the 4-year study period, the number of patients injured by e-scooters increased every year. Lower extremities were the most common injury site (67.2%) among riders, whereas injuries to the head and neck (64.3%) were more common in riders of non-electric scooters. Among the lower leg, ankle, and foot injuries of riders (52 cases), the ankle joint (53.8%) was the most commonly injured site, followed by the foot (40.4%) and lower leg (21.2%). The fracture group scored significantly higher on the Abbreviated Injury Scale than the non-fracture group (p < 0.001). Among the fracture group (20 cases), ankle fractures (9 cases) were most common, including pronation external rotation type 4 injuries (4 cases) and pilon fractures (2 cases). Five patients (25%) had open fractures, and 12 patients (60%) underwent surgical treatment. @*Conclusions@#The ankle and foot are the most common injury sites in e-scooter-related accidents. Given the high frequency and severity of e-scooter-related ankle and foot injuries, we suggest that more attention be paid to preventing these types of injuries with greater public awareness of the dangers of using e-scooters.
Résumé
Background@#Although the scallop sign is considered the most important risk factor for extensor tendon ruptures (ETRs) in patients with osteoarthritis of the distal radioulnar joint (DRUJ), previous reports provide a limited understanding of the changes at DRUJ, as risk factors were examined in plain radiographs of the wrist. The aim of this study was to assess the changes of DRUJ using axial images of computed tomography (CT) in patients with DRUJ osteoarthritis and associated ETRs and to evaluate the relationship between the changes of DRUJ and ETRs. @*Methods@#Twelve patients with ETRs due to osteoarthritis of the DRUJ were enrolled. The changes of DRUJ were examined on axial images of CT and the following 8 parameters were measured: width of radius, anteroposterior (AP) length of radius, width of sigmoid notch (SN), AP length of SN, AP length of ulnar head, subluxation length of ulnar head, dorsal inclination of SN, and distance from Lister’s tubercle to SN. Radiological parameters of the DRUJ were measured in 60 control wrists without trauma or osteoarthritis, and the patient and control groups were statistically compared. @*Results@#Statistically significant differences were observed between the patient and control groups in all the radiological parameters except for the AP length of SN and AP length of ulnar head. The width of radius, AP length of radius, width of SN, subluxation length of ulnar head, and dorsal inclination of SN were greater and the distance from Lister’s tubercle to SN was smaller in the patient group than in the control group. The width of SN, dorsal inclination of SN, and distance from Lister’s tubercle to SN were statistically significant risk factors among the 8 parameters. @*Conclusions@#ETRs due to osteoarthritis of the DRUJ was related to the changes of DRUJ, especially the changes around SN of the distal radius. In addition to the existing risk factors, a decreased distance from Lister’s tubercle to SN and increased dorsal inclination of SN were identified as new risk factors. Axial images of CT were effective to evaluate degenerative changes at the DRUJ.

Purpose@#Septic arthritis of the knee is an orthopedic emergency that requires early diagnosis and surgical treatment. This study examined the effectiveness of drain insertion and irrigation in the treatment of septic arthritis of the knee under local anesthesia. @*Materials and Methods@#A retrospective study was conducted on nine cases (eight patients) diagnosed with septic arthritis of the knee from September 2017 to February 2020 and treated with drain insertion and irrigation under local anesthesia. After penetrating through the superolateral portal to the superomedial portal and inserting the drain, daily irrigation of approximately 3 L of normal saline was done. The following were investigated: age, sex, underlying disease, cause, degree of osteoarthritis, time from diagnosis to surgery, duration of hospitalization, duration of normalization of C-reactive protein, and smear and culture. @*Results@#The initial white blood cell count of joint fluid was 71,472±51,667/mm3 (32,400–203,904/mm3 ), and polymorphic leukocytes were 91.1%±2.6% (86%–95%). The average time from diagnosis to surgery was 8.3±1.3 hours (6–10 hours), and the irrigation period was 8.2±3.2 days (4–15 days). The average length of hospitalization was 20.8±8.7 days (9–37 days). There was no reoperation or recurrence. Smear and culture tests were not identified. @*Conclusion@#In the treatment of septic arthritis of the knee, the insertion of a drain tube and irrigation under local anesthesia is a relatively fast and simple method to reduce pain by repetitive draining of purulent joint fluid and can be used as an alternative treatment for patients with a risk of general or spinal anesthesia.
Résumé
Purpose@#Radiocarpal dislocation (RCD), which is caused by high-energy trauma, often involves radial styloid fractures and short radiolunate ligament (SRLL) injuries. Although SRLL injuries may occur as a simple rupture at the attachment site of radius, it may occur with a relatively large avulsed-fragment in the volar rim of the lunate facet of the radius. This study aimed to differentiate the injury type of SRLL and assess the differences in the treatment results depending on the treatment methods that have been applied in RCD with radial styloid fractures. @*Materials and Methods@#Eighteen patients managed surgically with RCD were enrolled in this study. The patients were classified as Group 1 and Group 2 by using the Dumontier method. In this study, Group 2 was subdivided into 2A (purely ligamentous or small avulsion fracture of the volar rim of lunate facet) and 2B (large avulsed-fragment enough to internal fixation) according to the injury type of SRLL.Groups 2A and 2B were treated with direct repair and screw fixation, respectively. Pain, range of motion of the wrist joint, grip strength, and complications on final radiographs were examined. The outcomes were evaluated using patient-rated wrist evaluation (PRWE), and modified Mayo wrist score (MMWS). @*Results@#All patients were Group 2 (six and twelve patients in 2A and 2B, respectively). The mean flexion to extension arch recovered 79%,and the mean grip strength was 72.9% of the uninjured side. Group 2A showed better recovery in extension, flexion and pronation than Group 2B, but there was no difference in radial deviation, ulnar deviation, supination, grip strength and pain. No differences in the PRWE and MMWS were observed between two groups. Complications included traumatic arthritis in seven patients and residual instability in five patients. @*Conclusion@#When the SRLL was injured, the involvement of a large avulsion fracture on the anterior plane of the radiolunate did not affect the test results. On the other hand, it should be observed cautiously because avulsion fractures tend to disturb the joint’s reduction through rotation or displacement. In addition, anatomical reduction and sturdy internal fixation are important for restoring the function of the SRLL.
Résumé
Symmetrical Digital Gangrene (SDG) is characterized by the sudden onset of peripheral, symmetrical gangrene in the absence of any major vascular occlusive disease. Catecholamine inotropes are frequently used for the treatment of septic shock combined with an unstable hemodynamic state, and their usage can rarely induce SDG. There is no standard treatment for the SDG. Early recognition and prompt management of sepsis and expeditious process of weaning off of the inotropes are necessary to prevent progression of SDG. To the best of our knowledge, this is the first report in Korea regarding the treatment of SDG induced by catecholamine inotropes.

PURPOSE: This study aimed to investigate bicycle injury patients who suffered orthopedic injuries. METHODS: From January 1, 2010 to December 31, 2014, 1,664 people visited the emergency room due to a bicycle accident. Among them, 385 patients were found to have orthopedic injuries through physical examination and imaging evaluation. Intending to evaluate whether the number of bicycle injury patients is increasing or decreasing yearly, we investigated the rate of orthopedic injuries among bicycle injury patients, the damaged areas and the extent of damage, and also investigated whether changes in frequency were correlated with sex, age, or season. RESULTS: From January 1, 2010 to December 31, 2014, a total of 237,533 people came to the emergency room. Among them, the number of bicycle injuries was 1,664 (0.7%), and 23% of the bicycle injuries (385 people) were orthopedic injuries. Among these, 77.4% were men, 44.5% were less than 20 years old, and 20% were more than 61 years old. Damage to the forearm (n=82, 21.3%) and the shoulder (n=71, 18.4%) were the most common injuries, and simple fractures affected 274 patients (71.1%), overwhelmingly more common than other patterns of damage. In combination, simple fracture and dislocations occurred in 279 cases (72.5%). CONCLUSION: Most bicycle injuries occur in young and elderly people. Fractures of the forearm and shoulder were the most common orthopedic injuries. We expect that this study will be helpful in providing information about the orthopedic characteristics of bike injuries.

Atypical fractures have been reported as a complication of long-standing bisphosphonate therapy and occur commonly in the subtrochanteric region or shaft of the femur showing typical radiographic features. We encountered a case of atypical fracture of the proximal one-third of the shaft of the ulna. Radiographic findings of this case differed from previously reported cases of ulnar fracture in terms of showing a transverse fracture line with cortical thickening and an oblique fracture line with anterior cortical spike. On the other hand, these findings were similar to radiographic features of atypical femoral fractures. The present case was managed surgically and union of fracture was achieved after 6 months. As there are possibilities of occurrence of atypical fractures in sites other than the femur, the physicians should cautiously examine the patients' history and radiographic findings.

PURPOSE: An axillary crutch is the most commonly used assistive device in foot and ankle patients who require nonweightbearing. On the other hand, its use frequently induces axillary or wrist pain and critical neurovascular injuries have been reported in several studies. This study compared the clinical outcomes of patients using the knee walker and axillary crutch. MATERIALS AND METHODS: A retrospective analysis was performed comparing the utility of a knee walker and axillary crutch as a nonweightbearing ambulatory aid for 62 foot and ankle patients treated between November 2016 and March 2018. A comparative study of the two orthosis could be performed because all the patients temporarily used an axillary crutch before or after the use of a knee walker. A demographic study and comparative analysis based on the visual analogue scale (VAS) satisfaction score (0~100), complications, and fall down history were evaluated. Furthermore, under the assumption of having retreatment, their preference of orthosis between the knee walker and axillary crutch was investigated. RESULTS: The mean age of the patients was 36.5 and the mean duration of ambulation with a knee walker and axillary crutch were 5.2 and 2.4 weeks. The VAS satisfaction score of the knee walker and crutch was 88.8 and 27.5, respectively (p < 0.05). The most frequent complications of the knee walker and crutch were ipsilateral knee pain (6 cases) and axillary or wrist pain (56 cases), respectively. No case of falling down occurred during knee walker ambulation, but there were two cases of crutch ambulation. Fifty-eight patients (93.5%) preferred the knee walker and four patients (6.5%) preferred a crutch. CONCLUSION: Compared to the axillary crutch, the knee walker afforded lower complication and higher satisfaction. Most patients preferred the knee walker to a crutch. Therefore, the knee walker is an efficient and safe orthosis for foot and ankle patients who require nonweightbearing.

BACKGROUND: The sagittal alignment of the spine and pelvis is not only closely related to the overall posture of the body but also to the evaluation and treatment of spine disease. In the last few years, the EOS imaging system, a new low-dose radiation X-ray device, became available for sagittal alignment assessment. However, there has been little research on the reliability of EOS. The purpose of this study was to evaluate the intrarater and interrater reliability of EOS for the sagittal alignment assessment of the spine and pelvis. METHODS: Records of 46 patients were selected from the EOS recording system between November 2016 and April 2017. The exclusion criteria were congenital spinal anomaly and deformity, and previous history of spine and pelvis operation. Sagittal parameters of the spine and pelvis were measured by three examiners three times each using both manual and EOS methods. Means comparison t-test, Pearson bivariate correlation analysis, and reliability analysis by intraclass correlation coefficients (ICCs) for intrarater and interrater reliability were performed using R package “irr.” RESULTS: We found excellent intrarater and interrater reliability of EOS measurements. For intrarater reliability, the ICC ranged from 0.898 to 0.982. For interrater reliability, the ICC ranged from 0.794 to 0.837. We used a paired t-test to compare the values measured by manual and EOS methods: there was no statistically significant difference between the two methods. Correlation analysis also showed a statistically significant positive correlation. CONCLUSIONS: EOS showed excellent reliability for assessment of the sagittal alignment of the spine and pelvis.

Résumé
STUDY DESIGN: Literature review. 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.

Panner's disease, osteonecrosis of the capitellum of the elbow, was first reported by Panner in 1927. The disease occurs mainly in boys between 6 and 15 years old and shows unilateral distribution. Pain, stiffness, localized tenderness over the lateral condyle of the elbow, and decreased range of motion are the typical clinical symptoms. Conservative treatment is generally recommended for patients in the early stage of this disease. A few cases of Panner's disease have been reported and few are related to long-term follow-up results. To the best of our knowledge, all reported cases were over six years. Therefore, we report on a five-year-old boy diagnosed as Panner's disease that showed resorption and regeneration of the humeral capitellum with no limitation of motion over three years. The current study was exempted from review by the institutional review board because it was a single retrospective case report. Informed consent was obtained from the patient's guardian.

PURPOSE: The purpose of this study was to evaluate the effect of steroid injection according to the stage of Finkelstein's test and the severity of tenderness on radial styloid in de Quervain's disease. METHODS: Between January 2011 and December 2012, a total of 57 patients (57 wrists) treated with steroid injection in de Quervain's disease were enrolled on this study. The severity of tenderness, the stage of Finkelstein's test and pain score using visual analogue scale (VAS) were assessed before steroid injection. And the effect of steroid injection was assessed until one year after steroid injection. The relationship between the recurrence of de Quervain's disease after steroid injection and pre-injection findings including tenderness, Finkelstein's test and VAS was assessed. RESULTS: The success rate of steroid injection was 71.9% (41/57 patients). The outcome of steroid injection was not significantly related to the severity of tenderness (p=0.648), the stage of Finkelstein's test (p=0.530) and VAS score (p=0.607). CONCLUSION: The tenderness on radial styloid and the Finkelstein's test are important physical findings for the diagnosis of de Quervain's disease. However, the severity of tenderness and the stage of Finkelstein's test were not showed as predictive factors for the outcome.

In tetraplegia patients, activities of daily living are highly dependent on the remaining upper limb functions. In other countries, upper limb reconstruction surgery to improve function has been applied to diverse cases, but few cases have been reported in Korea. The current authors experienced a case of posterior deltoid-to-triceps tendon transfer and rehabilitation in a complete spinal cord injury with a C6 neurologic level, and we introduce the case-a 36-year-old man-with a literature review. The patient's muscle strength in C5 C6 muscles were normal, but C7 muscles were trace, and the Spinal Cord Independence Measure III (SCIM III) score was 24. The tendon of the posterior deltoid was transferred to the triceps brachii muscle, and then the patient received comprehensive rehabilitative treatment. His C7 muscle strength in the right upper extremity was enhanced from trace to fair, and his SCIM III score improved to 29.

Methods about removal of intramedullary nail in complicated cases were reported in some literatures but there are no reports about nail removal in the ulna. The authors would like to report such a case and the technique. We removed bone of the inlet site and created another bony window using an osteotome to expose the interlocking screw holes. Only a bony window the size of 2 inter-interlocking holes at the most proximal part of the nail can be used to remove the nail with minimal damage of the triceps brachii tendon and soft tissue.

There are three compartments of the forearm by fascia: volar, dorsal and lateral. Compartment syndrome of the forearm, which commonly develops in the volar deep compartment, can be induced by various causes. We experienced a case of acute dorsal compartment syndrome of the forearm in a patient with rhabdomyolysis. Because of severe pain and progressive palsy of the posterior interosseous nerve, fasciotomy and release of posterior interosseous nerve were performed. Acute compartment syndrome localized at the dorsal compartment of the forearm is very rare, and compartment syndrome of the forearm in a patient with rhabdomyolysis has not been reported previously. We report the case with review of literatures.
