The Use of Halo Gravity Traction in Severe, Stiff Scoliosis.

PURPOSE: The correction of severe, stiff scoliosis in children is challenging. One method used to reduce the risk is preoperative halo gravity traction (HGT). In this study, the authors sought to define the efficiency and safety of HGT and characterize the chronology of the correction seen. METHOD: A consecutive group of pediatric patients with severe spinal deformities was treated with HGT before definitive correction. A standard protocol with the daily addition of weight to 50% of body weight at 3 weeks was used. Traction remained in place until signs of impending neurological complication or 6 weeks, whichever was sooner. RESULTS: Twenty-four patients were included with a mean age of 11.8 years. The mean coronal deformity was 123 degrees, with a T1-L5 height of 234 mm. The mean duration of traction was 42 days with a mean improvement in height of 72 mm with 82% occurring over the first 3 weeks. Hundred percent of the angular and 98% of T1-L5 height correction was reached by 6 weeks.One patient showed early signs of a cranial nerve palsy prompting early surgery and 8 patients showed pin loosening, 1 of which required revision of their halo. One patient underwent a slower progression of traction because of transitory urinary disturbance. Following fusion, angular correction of the major curve was 49%. CONCLUSION: HGT is a safe treatment for severe, stiff scoliosis because it can respond to early signs of impending neurological impairment. The first 3 weeks of treatment, reaching 50% of body weight as a traction force accounts for 80% of correction, with the remaining 20% in the following 2 weeks. At least 4 weeks of traction is recommended when following this protocol.

Evaluation of hip arthroscopy using a hip-specific distractor for the treatment of femoroacetabular impingement.

BACKGROUND AND STUDY AIMS: Hip arthroscopy using an orthopaedic traction table has been associated with traction-related neurovascular complications. Since the use of a hip-specific distractor for performing hip arthroscopy hasn't been associated with those specific complications we hypothesized that a hip-specific distractor might facilitate the learning curve of hip arthroscopy for beginner surgeons. MATERIAL AND METHODS: We reviewed retrospectively the first 56 hip arthroscopies performed to treat femoro-acetabular impingement using a hip-specific distractor. We tried to analyse the learning curve of this procedure using operative time, peri- and postoperative complications, hospital stay and patient satisfaction. We also evaluated pre- and postoperative sports activities and tried to identify some factors as poor postoperative prognostic factors. RESULTS: Only 1 major complication occurred. No traction-related complications have been encountered. The curves analysing intervention time and postoperative satisfaction rate showed improvement after 30 cases performed. In all cases, we were able to perform the whole planned gesture without difficulties accessing the hip joint. CONCLUSION: The hip-specific distractor is a safe and reproducible method in performing hip arthroscopy without any traction-related complications or time limits.

Total hip arthroplasty through the direct anterior approach with and without the use of a traction table: a matched-control, retrospective, single-surgeon study.

BACKGROUND: Hip surgeons performing total hip arthroplasty (THA) through the direct anterior approach (DAA) commonly use a traction table to facilitate exposure. Even though performing THA through DAA without a traction table could be technically more demanding, this technique offers the advantage of intraoperative leg length comparison. Therefore, this study aimed to compare clinical outcomes, complication rates, component positioning, and leg length discrepancy (LLD) after THA through the DAA performed with or without a traction table. METHODS: A single-surgeon continuous series of 75 patients who underwent DAA THA performed with a traction table was matched for gender, age, and BMI with 75 patients who underwent DAA THA performed without a traction table (male, 62; female, 88, with an average age of 68 years old). Clinical and radiological outcomes, intra- and postoperative complications, and LLD were retrospectively assessed. RESULTS: No statistically significant difference was detected in surgical time, hospital stay, Harris Hip Score (HHS), complication rates, and implant positioning between the two groups. Leg length restoration was significantly more accurate in the group performed without a traction table (2.4 ± 2 mm vs. 3.7 ± 3.1 mm; p value ≤ 0.05). No LLD > 10 mm was reported in the group performed without a traction table, whereas two cases (2.7%) were reported in those performed with a traction table. CONCLUSION: Performing THA through DAA without a traction table was associated with a significantly more accurate leg length restoration without a significant increase in the rates of intra- and postoperative complications.

Successful endotracheal intubation using i-gel supraglottic airway device and ultrasonography in a patient with bedside cervical traction: A case report.

We report a case of successful endotracheal intubation using i-gel and ultrasonography without a laryngoscope in a patient with a bedside cervical traction device. A 57-year-old man was referred to the emergency department because of quadriparesis following a motor vehicle accident, who was confirmed to have cervical dislocation with spinal cord compression. For ventilation support, the i-gel rescue airway device was placed to secure the patient airway temporarily. Then, an endotracheal tube was passed through the stem of the i-gel while observing the optimal tube position with ultrasonography. This case showed that ultrasonography can be used for early confirmation of endotracheal tube placement into the trachea via the i-gel.

Non-surgical correction of cryptotia.

INTRODUCTION: Cryptotia is characterized by an absence of the upper part of the temporoauricular sulcus with the superior third of the auricle buried under the temporal skin. The principle of correction of cryptotia is to achieve both a functional and aesthetic ear. METHODOLOGY: A 4-year prospective study was carried out in a single centre on infants with cryptotia. We introduce a two-staged approach for non-surgical correction of cryptotia and a treatment algorithm based on the age of the patient. In the first stage, we unbury the auricle over 2 weeks. The second stage involves 2 additional weeks of helical moulding to correct the underlying or residual deformation. In our algorithm, patients more than 6 weeks of age undergo only the first stage of cryptotia correction, whereas those less than 6 weeks of age progress to the second stage of treatment. RESULTS: A total of 5 patients (7 ears) were treated with ages ranging from 1 day to 7 months. Two patients underwent 2-stage treatment and 3 underwent 1-stage treatment. At 1 year, all buried helices remained retracted. Four out of 7 ears treated had "Excellent" outcomes and 3 out of 7 ears had "Good" outcomes. All caregivers were extremely satisfied with the outcomes. CONCLUSION: This simple and efficacious two-stage technique and algorithm is effective in the correction of cryptotia, even if the treatment is initiated beyond the traditional moulding window in the first six weeks of life. Using this approach, patients with cryptotia benefit by avoiding or simplifying surgical reconstruction in the future.

Halo Femoral Traction for 1 Week Between Staged Anterior and Posterior Fusion Surgeries for Severe Adolescent Scoliosis Is Effective and Safe.

OBJECTIVE: To report the outcomes of halo femoral traction (HFT) used for 1 week between anterior release and definitive posterior fusion in adolescents with severe rigid scoliosis. METHODS: A retrospective single-center review of 22 consecutive patients (mean age at surgery, 14.1 years; range, 10.5-18.2 years; 17 girls) with severe, rigid scoliosis treated with anterior release, followed by HFT for 7 days prior to posterior instrumented fusion. Cobb angles were measured preoperatively, 1 week after anterior release and traction, after posterior fusion, and at a minimum 2-year follow-up. Complications were recorded. RESULTS: Mean preoperative Cobb angle was 97° (range, 80°-118°), correcting to 52° with anterior release and HFT and 31° after posterior fusion. This equated to a 68% deformity correction and was maintained at final follow-up. Three traction-related complications were experienced, including 1 case of neck pain and 2 cases of brachial plexopathy that resolved with traction weight reduction. CONCLUSIONS: Three-staged deformity correction using HFT for 1 week only offers gradual correction of the spine over sufficient time to optimize deformity correction yet minimizes neurologic dysfunction.

Calcaneus traction compression with orthopaedic reduction forceps combined with percutaneous minimally invasive treatment of intra-articular calcaneal fractures: An analysis of efficacy.

BACKGROUND: The treatment of displaced calcaneal fractures is controversial.Open reduction and internal fixation are widely described as the gold standard in the literature,but these technique shave many complications,including skin necrosis,internal fixation leakage and deep infection and wound healing problems.Percutaneous reduction and unilateral external fixation have received increasing attention because they can provide a good, stable reduction and reduce the soft tissue complications caused by open surgery(such as deep infection and delayed wound healing).The purpose of this retrospective study was to evaluate the reduction imaging and clinical results of calcaneus traction compressionwith orthopaedic compression reduction forceps combined with percutaneous minimally invasive external fixation for intra-articular calcaneal fractures. METHODS: This was a retrospective analysis. A total of 35 patients with unilateral calcaneal fractures were divided into two groups: 1) the open reduction, internal fixation group (19 feet)and 2) the percutaneous minimally invasive, closed reduction external fixation group (16 feet).Evaluation of the reduction include dimaging measurements of the calcaneus length,width,and height,and the Bohler angle and Gissane angle before and after surgery.Clinical outcomes included the time of surgery,length of hospital stay,operation time,wound-related complications,the American Orthopaedic Foot and Ankle Society hindfoot score,the visual analogue score for pain, and the SF-36 score. RESULTS: The average follow-up time was 25.52 ± 1.68 months.There was no significant difference in reduction between the open group and the closed group (P > 0.05).The operation time of the open group was significantly longer than that of the closed group(P = 0.0001).The length of hospitalization and waiting time for surgery in the open reduction group were significantly longer than those in the closed reduction group (P < 0.05).Incidence-related complications in the open group and closed group were 21.1 %(4/19) and 6.3 %(1/16),respectively (P = 0.0001).The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scores in the open and closed groups were 81.35 ± 5.25 and 82.52 ± 4.78, respectively (P = 0.0875). The visual analogues cale (VAS) scores of the open group and the closed group were 1.81 ± 1.32 and 0.78 ± 0.91, respectively (P = 0.0412).The SF-36 scores were 80 ± 4.5 and 79 ± 4.2, respectively. CONCLUSION: Our research shows that for various types of intra-articular calcaneal fractures compared with open reduction,internal plate fixation,calcaneus traction compression with orthopaedic reduction forceps combined with percutaneous minimally invasive external fixation is a simple and effective method for treating calcaneal fractures; not only can the calcaneus be corrected, but it can also provide notable imaging and clinical results.

Internal traction method using a spring-and-loop with clip (S-O clip) allows countertraction in gastric endoscopic submucosal dissection.

BACKGROUND: Insufficient countertraction and poor field of vision make endoscopic submucosal dissection (ESD) difficult. Internal traction method using a spring-and-loop with clip (SLC) allows sufficient traction in any direction and good field of vision. However, the attachment procedure is difficult and interference with the endoscope can occur in the retroflexed endoscopic position. We have developed a new use of SLC that simplifies the attachment procedure, eliminating interference with the endoscope. The aim of this study was to investigate the efficacy of SLC for gastric ESD. METHODS: We retrospectively recruited 140 patients with gastric neoplasms who underwent ESD between November 2015 and October 2018 at our department. Among them, 51 patients treated using SLC-assisted ESD (SLC-ESD) and 89 patients treated using conventional ESD (C-ESD) were compared. Propensity score matching was performed to compensate for the differences in age, sex, lesion location, lesion position, specimen size, and ulcer findings. The primary outcome was ESD procedure time. RESULTS: Propensity score matching generated 51 matched pairs. The procedure time in the SLC-ESD group was significantly shorter than that in the C-ESD group (median [interquartile], 40.0 [27.0-81.5] minutes versus 69.0 [46.5-113.5] minutes, P = 0.008). The mean SLC attachment time was 2.08 min. There were no significant differences in complete en bloc resection rate between SLC-ESD and C-ESD groups (100% versus 96.1%, P = 0.495). There were not perforation cases in either group. CONCLUSIONS: SLC may offer an efficient method for gastric ESD, with a short attachment procedure time.

Development of a spring-based weight system for halo gravity traction for complex pediatric spinal deformity.

STUDY DESIGN: Description of technique. OBJECTIVES: Describes the redesign of free-weight-based halo gravity traction wheelchairs and walkers to a spring-based system. The treatment of severe pediatric spinal deformities is challenging and associated with significant morbidity. Halo gravity traction (HGT) can be utilized to assist in the correction of severe spinal deformities. A time period of traction may also be used to medically optimize patients prior to surgery. Implementing HGT therapy requires specialized equipment, specially trained hospital staff, as well as significant commitment from caregivers. This study describes the transition from a free weight-based HGT equipment to a spring-based weight system. The new system is expected to decrease the burden of care and improve safety for patients and their families. METHODS: A thorough interview process was carried out to gather data on existing HGT systems. All stakeholders, including orthopedic technicians, nurses, surgeons, patients and their families were asked questions on how to improve the equipment and process. With colleagues at a partner children's hospital, new HGT wheelchairs and walkers with a spring-based weight system were designed and built. RESULTS: Spring-based weight HGT wheelchairs and walkers are more economical to build, safer, and easier to operate than free-weight-based systems. A cost analysis found that spring-based systems cost $780 less compared to free weight-based systems. In addition, the new spring-based wheelchairs and walkers are about 50% lighter with improved weight distribution making them safer to operate and easier to transport. There is consensus among surgeons, nurses, and families that the redesigned units are easier to operate. CONCLUSIONS: Spring-based weight HGT systems are economically viable and clinically effective for pre-operative traction for children with severe spinal deformities. They are well tolerated by patients and easy to care for by nursing and surgical staff. LEVELS OF EVIDENCE: III.
