Temporary immobilization methods for closed low-energy ankle fracture-dislocations: comparative analysis of a retrospective cohort.

PURPOSE: Ankle fracture-dislocations (AFD) often necessitate staged management involving temporary external fixation (EF) due to mechanical instability or blistering. However, limited literature exists on the optimal temporary immobilization method for low-energy closed AFD. This study compared baseline patient and fracture characteristics, along with clinical and radiological outcomes between AFD initially immobilized with EF versus splinting. METHODS: A retrospective cohort study was conducted involving patients with AFD temporarily immobilized using EF or splinting, followed by definitive open reduction and internal fixation. Quality of reduction (QOR) was assessed for each patient post-initial immobilization and after the definitive surgery. RESULTS: The study encompassed 194 patients: 138 treated with a splint (71.1%) and 56 (28.9%) with EF. Secondary loss of reduction had occurred in three patients who were splinted (2.2%). The mean ages in the EF and splint groups were 63.2 and 56.1 years, respectively (p = 0.01). Posterior malleolus fracture (PMF) and blisters were more prevalent in EF patients (69.6% vs. 43.5% for PMF and 76.8% vs. 20.3% for blisters, respectively; p = 0.05 and p < 0.01). Postoperative complication rates were 8.9% for EF versus 10.9% for splinting (p = 0.69). Satisfactory final QOR was attained in 79.8% of patients treated with a splint versus 64.3% with EF (p = 0.02). CONCLUSION: Patients immobilized by EF presented with poorer baseline characteristics and had more unstable injuries. Nevertheless, postoperative complication rates were comparable. Thus, EF appears to be a valuable tool for standardizing outcomes in AFD patients with a less favorable prognosis.

INTRABDOMINAL PRESSURE AND ITS CORRECTION IN ACUTE SURGICAL PATHOLOGY.

OBJECTIVE: The aim: Improving the results of treatment of patients with acute surgical pathology of the abdominal cavity by correcting intra-abdominal hypertension (IAH). PATIENTS AND METHODS: Materials and methods: The results of examination and treatment of 187 patients with acute surgical pathology, which was accompanied by elevation of IAP. To compare the results, depending on the chosen diagnostic and treatment tactics, patients were divided into two groups: comparison and main. The comparison group (85 people (45,5%) included patients who have been treated with traditional approaches in diagnosis and treatment according to existing treatment protocols. The main group (102 people (54,5%) included patients in whose treatment we additionally used our proposed step-by-step approach in the treatment of IAH. RESULTS: Results: Systemic complications occurred in 12 patients of the main group (11,8%) and in 46 patients of the comparison group (54,1%), while in the second group the frequency of systemic complications was significantly higher (χ2 = 38,6, CI 29,3-53,6, p <0,0001). 20 patients (10,7%) died (2 patients of the main group (1,96%) and 18 patients of the comparison group (21,2%) (χ2 = 17,85, CI 10,4-29,18, p <0,0001). CONCLUSION: Conclusions: Use in the complex treatment of patients with acute surgical pathology of the abdominal cavity, accompanied by IAH, the proposed step-by-step approach has improved treatment outcomes by reducing the incidence of systemic complications from 54,1% to 11,8%, total mortality from 21,2% to 1,96% and postoperative mortality - from 22,4% to 2,4%.

[Damage control strategy in surgical treatment of patients with severe gastroduodenal bleeding]. / Primenenie strategii Damage control pri khirurgicheskom lechenii patsientov s tyazhelymi gastroduodenal'nymi krovotecheniyami.

OBJECTIVE/: To objectify patient condition and improve treatment outcomes in patients with benign severe gastroduodenal bleeding. MATERIAL AND METHODS: We analyzed the immediate results of staged surgical treatment of patients with benign severe gastroduodenal bleeding according to the accepted concept of «Damage Control Surgery¼. The Rockall risk scoring system and the Glasgow-Blatchford score (GBS) were used. We preferred two-stage intervention in patients with Rockall score ≥5 and Glasgow-Blatchford score ≥11. RESULTS: Staged approach according to the concept of «Damage Control Surgery¼ in patients with benign severe gastroduodenal bleeding ensures positive results by minimizing surgical trauma and perioperative bleeding, early stabilization of hemostasis and subsequent successful restoration of digestive function. CONCLUSION: The concept of «Damage Control Surgery¼ in patients with benign severe gastroduodenal bleeding can reduce mortality and incidence of postoperative complications.

[Efficiency of staged rehabilitation treatment of patients with chronic endometritis and reproductive disorders]. / Effektivnost' etapnogo vosstanovitel'nogo lecheniya patsientok s khronicheskim endometritom i reproduktivnymi narusheniyami.

The use of physical factors according to the principles of syndromic-pathogenic approach with the patients suffering from chronic endometritis ensures the restoration of physical and mental health. OBJECTIVE: To evaluate and scientifically substantiate therapeutic effects of staged rehabilitation treatment of the patients with chronic endometritis and reproductive disorders including therapeutic physical factors. MATERIAL AND METHODS: There have been observed 103 patients of childbearing age with chronic endometritis and reproductive disorders. They were divided into two groups by simple randomization. In the control group (n=49), the treatment was based on clinical guidelines and included antibacterial pharmacotherapy and magnetic laser therapy in combination with intravaginal magnetic laser electrical stimulation. In the main group (n=54), this treatment was carried out at the I and II stages, however, at the II stage, a pulsed low-frequency electrostatic field was additionally included in the treatment program; clay therapy was included at the III stage. Clinical monitoring, cytokine status, and regional circulation were used to assess the effectiveness of the treatment. RESULTS: After a staged rehabilitation treatment, the reduction of clinical manifestations was observed in the main group in 89.2% (p<0.01) of cases, while in the control group - in only 76.5% (p<0.01). The patients of the main group had a decrease in the level of pro-inflammatory cytokines on average by 44.0% (p<0.01), whereas the level of anti-inflammatory cytokines increased on average by 29.6% (p<0.01). In the control group the dynamics of cytokine activity indicators was lower by 18-20% (p<0.05). The use of physical factors provided a significant improvement in regional hemodynamics, and in all the cases there was a significant significance in relation to similar indicators in the control group. The effectiveness of personalized programs of rehabilitation treatment of the patients suffering from chronic endometritis and reproductive disorders was 78.4%, and standardized programs - 59.5%. CONCLUSION: Staged rehabilitation treatment of chronic endometritis and infertility with the use of physical factors at each stage ensures the leveling of pain and inflammatory syndromes, improvement of immune status, pelvic hemodynamics, which, in general, provides an increase in the effectiveness of rehabilitation treatment of this category of patients by 18.9% (p<0.05).

Stationary distribution and extinction of a stochastic staged progression AIDS model with staged treatment and second-order perturbation.

Focusing on deterministic AIDS model proposed by Hyman (2000) and the detailed data from the World Health Organization (WHO), there are three stages of AIDS process which are described as Acute infection period, Asymptomatic phase and AIDS stage. Our paper is therefore concerned with a stochastic staged progression AIDS model with staged treatment. In view of the complexity of random disturbances, we reasonably take second-order perturbation into consideration for realistic sense. By means of our creative transformation technique and stochastic Lyapunov method, a critical value R 0 H > 1 is firstly obtained for the existence and uniqueness of ergodic stationary distribution to the stochastic system. Not only does it respectively reveal the corresponding dynamical effects of the linear and second-order perturbations to the model, but the unified form of second-order and linear fluctuations is derived. Next, some sufficient conditions about extinction of stochastic system are established in view of the basic reproduction number R 0 . Finally, some examples and numerical simulations are introduced to illustrate our analytical results. In addition, some advantages of our new method and theory are highlighted by comparison with other existing results at the end of this paper.

Does a staged treatment of high energy tibial plateau fractures affect functional results and bony union? A case series.

PURPOSE: Tibial plateau fracture (TPF) is a devastating injury as it shatters lower articular surface of the largest joint. Apart from bony injury, TPF can lead to great soft tissue envelope compromise which affects the treatment plan and outcome. In the present study, clinical results were assessed in cases of high energy TPFs treated in staged manner. METHODS: Twenty-three (20 males and 3 females) patients of high energy communited TPFs (Schatzker type V and VI) were consecutively treated.1 All the patient had compromise of overlying skin conditions. They were all successively scheduled for staged treatment plan which comprised of application of bridging knee external fixator on the first day of admission and definitive internal fixation after skin and soft tissue overlying the fracture were healed. Schatzker type I, II, III and IV were excluded from the study. Primary survey was done and patient who had head injury, chest and abdominal injury, pelvic injury and contralateral limb injury and open fractures were excluded from the study. The patients were also evaluated in terms of wound complications, axial and rotary alignment of limb, fixation failure, articular congruity and range of motion of the knees and post injury employment. Statistical analysis was done using SPSS software. RESULTS: Maximum follow-up period was 13 months. All the fractures were united at final follow-up. Clinical evaluation was done with the Tegner Lysholm knee scoring scale.2 Excellent results were found in 78% cases and good and fair results in 22% cases. There was significant correlation between range of motion and the Tegner Lysholm knee score (p < 0.001, Pearson correlation coefficient = 0.741). The correlation between the score and the radiographical union duration was significant (p = 0.006, Pearson correlation coefficient = -0.554). CONCLUSION: A staged treatment plan allows healing of soft tissue envelope, with avoidance of dreadful complications such as compartment syndrome and chronic infection. In addition, a staged treatment strategy does not hamper the fracture reduction, bony union and the functional results.

Staged internal plate fixation of severe lower extremity fractures that use a temporary external fixator for the initial treatment as an intraoperative retention tool: a technical note.

Staged treatment for severe lower extremity fractures is coming into widespread use, and some reports have described internal fixation (IF) using a temporary external fixator for primary care as an intraoperative retention tool. However, the infection risk with this procedure has not been examined sufficiently. To our knowledge, this article is the first report focusing exclusively on this specific surgical technique. A key point of our developed protocol for internal plate fixation with this technique to avoid postoperative infection is a precisely structured sterilization procedure, which required multiple changes of sterile surgical gloves. In all 19 fractures treated with our set protocol, postoperative infection did not occur. In this regard, however, a goal of definitive IF at the time of initial treatment is essential for this specific procedure. This technique could help orthopaedic trauma surgeons to import a temporary external fixator into the operative field for definitive IF, with less concern regarding risk of infection.

[Comparative histological analysis of different materials used for urethroplasty in children with proximal forms of hypospadias: preputial skin vs buccal mucosa].

AIM: Buccal mucosa and preputial skin grafts are used for staged urethroplasty in proximal forms of hypospadias in children. Aim of our study was to carry out a comparative histological analysis of preputial skin and buccal mucosa. METHOD: s and materials: Histological analysis of urethral tissue samples from 10 patients with proximal forms of hypospadias was conducted. All patients were treated with staged Brackas technique using free grafts at the Russian Childrens Clinical Hospital from 2013 to 2016. Patients were divided into two groups. In Group I (n=5), preputial skin graft was used for urethroplasty, while in Group II (n=5) buccal mucosa was taken. A histological study of both materials with comparison to a native urethra was performed. RESULTS: In Group I, the histological analysis showed keratinizing multilayered squamous epithelium, large number of dilated sweat and sebaceous glands with signs of inflammation, and hair follicles. In Group II, histological analysis revealed the presence of the typical structure for mucosal tissue, including multilayered flat non-keratinizing epithelium, as well as full absence of sweat, sebaceous glands, and hair follicles. CONCLUSION: comparative histological analysis of neourethra has shown the absence of sweat and sebaceous glands, hair follicles, and areas of chronic inflammation in buccal mucosa vs preputial skin, showing that buccal mucosa is more similar to native urethra. Therefore, buccal mucosa is favored as the material for urethroplasty.

Clinical and radiological outcome of Gustilo type III open distal tibial and tibial shaft fractures after staged treatment with posterolateral minimally invasive plate osteosynthesis (MIPO) technique.

OBJECTIVES: To evaluate the methods and the outcomes of Gustilo type III open distal tibial and tibial shaft fractures with severe anterior and medial soft-tissue injuries, treated with posterolateral minimally invasive plate osteosynthesis (MIPO) technique. METHODS: From May 2015 to May 2016, 10 patients with Gustilo type III open distal tibial and tibial shaft fractures with severe anterior and medial soft-tissue injuries (Gustilo-Anderson classification IIIA, 6; IIIB, 4) were treated with staged protocol using posterolateral minimally invasive plate osteosynthesis (MIPO) technique. The initial wound lavage, debridement, and application of a spanning external fixator were performed within 24 h and the mean interval from injury to definitive surgical treatment was 12.8 (range 4-21) days. An additional bone graft was performed in two patients when definitive internal fixation was performed. All patients were followed to union. Postoperative radiographs, postoperative complications, bone union, ankle joint motion, and limb functional outcome information of AOFAS ankle-hindfoot score were recorded. RESULTS: The mean follow-up period was 17.8 (range 12-26) months. The mean interval to bony union was 25.8 (range 20-40) weeks. Bone union was achieved in all cases. There were no complications, such as incision breakdown, deep infection, or impingement of the flexor hallucis longus tendon. The average AOFAS score was 90 (range 83-96). In ten patients, two patients had a superficial wound infection and another one patient showed a 6° varus deformity. CONCLUSIONS: Staged treatment using MIPO technique through a posterolateral approach is a reasonable and safe treatment option for open distal tibial and tibial shaft fractures, especially Gustilo type III with severe anterior and medial soft-tissue injuries. However, it should have a higher level of research evidence in more patients to confirm the safety of the clinical application of this technique.

Early posterior column internal fixation: A staged treatment of type C3 tibial pilon fracture.

Pilon fractures represent a challenging subset of tibial fractures. The management of AO/OTA Type C3 fractures remains complex due to associated complications and lack of clear guidelines for surgical timing and methods. A prospective cohort study was conducted to evaluate two staged treatment strategies for AO/OTA Type C3 tibial pilon fractures. The study focused on assessing surgical difficulty, complications, and patient prognosis. One group of patients received early internal fixation of the fibula and tibial posterior column combined with external fixation, while the other group received external fixation alone in the first stage. Patients who received early internal fixation of the fibula and tibial posterior column combined with external fixation had better outcomes, including lower rate of allogeneic bone grafting (67.74 % versus 94.64 %), reduced incidence of wound delay and skin necrosis (3.23 % versus 21.43 %), shorter surgical time (133.06 ± 23.99 min versus 163.04 ± 26.83 min), shorter hospital stay (13.77 ± 2.53 days versus 18.25 ± 3.67 days), and higher AOFAS (83.05 ± 8.68 versus 79.36 ± 8.92). Additionally, avoiding fibular shortening was shown to be crucial in preventing prolonged surgery and improving patient function. The study demonstrated that the staged treatment approach with early internal fixation led to shorter operative times, improved ankle function, and reduced complications, including a lower risk of infection. The findings support the use of this treatment to optimize outcomes in AO/OTA Type C3 pilon fractures.

Surgical Management of Ipsilateral Internal Carotid Artery Stenosis and Unruptured Intracranial Aneurysm: Case Review and Treatment Considerations.

Introduction The coexistence of carotid artery stenosis and a concomitant downstream ipsilateral unruptured intracranial aneurysm requires unique treatment considerations to balance the risk of thromboembolic complications from carotid artery stenosis and the risk of subarachnoid hemorrhage from intracranial aneurysm rupture. These considerations include the selection of optimal treatment modalities, the order and timing of interventions, and potential management of antiplatelet agents with endovascular approaches. We present strategies to optimize treatment in such a case. Case Report We discuss the case of a 69-year-old woman with 90% stenosis of the right internal carotid artery and an ipsilateral, wide-necked, 4.8-mm, irregular-appearing right A1-2 junction aneurysm with an associated daughter sac. Open, endovascular, and mixed treatment strategies were considered. The patient selected and underwent a staged, open treatment approach with a carotid endarterectomy followed by a right craniotomy for microsurgical clipping of the aneurysm 5 days later. Both procedures were performed on daily full-dose aspirin without complications. On follow-up, the right carotid artery was widely patent, the aneurysm was secured, and the patient remained at her neurologic baseline. Discussion The presented strategy for ipsilateral carotid artery stenosis and an unruptured intracranial aneurysm initially optimized cerebral perfusion to mitigate ischemic risks while permitting timely aneurysm intervention without a need for dual antiplatelet therapy or to traverse an earlier procedure site.

Staged treatment of bicondylar tibial plateau fractures: influence of frame configuration and quality of reduction on outcomes.

PURPOSE: Despite evolving treatment, the surgical management of high-energy tibial plateau fractures (TPF) remains challenging, associating high rates of complications. In recent decades, staged management has emerged as an encouraging option. The main goal of our study was to evaluate the influence of bridging external fixation (EF) frame configuration and the resultant quality of reduction (QOR) on outcomes after staged-treatment of bicondylar TPF. METHODS: A retrospective review was conducted of patients with bicondylar TPF treated at our level-I trauma center using a staged-treatment protocol from January 2010 to January 2020. Data on baseline characteristics, injuries, treatments, and clinical/radiological results were collected. The QOR was evaluated on CT images after EF and on plain films after ORIF. RESULTS: Sixty-eight patients were eligible for analysis. By our criteria, QOR was good in 57.4% and 70.6% after EF and ORIF, respectively. A squared EF configuration was associated with superior EF QOR (p = 0.032), while better EF QOR was linked to improved ORIF QOR (p = 0.016). No relationship between ORIF delay and ORIF QOR was identified. Postoperative complications were documented in 19 patients. Average ROM at one-year follow-up was 114.9 ± 12.6°, and non-influenced by anterior femoral pin placement. CONCLUSIONS: Staged management of bicondylar TPF resulted in a reasonable rate of complications. A direct relationship between QORs obtained with EF and after ORIF was found. Squared frames were associated with faster and better reductions, regardless of the surgeon's background. Considering our results, we advocate for the wider use of squared EF configurations in these patients.

Early Reduction of the Posterior Column: A Surgical Technique in AO/OTA C3 Tibial Pilon Fractures.

Staged treatment for pilon fractures is widely accepted. It remains to be discussed how to reduce and fix posterior column fractures while avoiding clinical complications. We provided a staged treatment protocol with detailed surgical techniques for closed AO Foundation/Orthopaedic Trauma Association (AO/OTA) C3 tibial pilon fractures with fibular fractures. In the first stage, the internal fixation of the fibula and distal tibial posterior column is accompanied by an external fixator. After swelling, the medial and anterior columns were fixed via the posteromedial approach in the second stage. We advocate early reduction and fixation of the posterior column and lateral column. The right timing of surgery can ensure well-reduced articular surface and alignment while minimizing soft tissue complications.

Staged Treatment of Posttraumatic Tibial Osteomyelitis with Rib Graft and Serratus Anterior Muscle Autografts-Case Report.

Osteomyelitis of the tibia is a challenging condition, particularly when it occurs as a result of trauma. This abstract presents a case study detailing the successful staged treatment of posttraumatic tibial osteomyelitis utilizing a unique combination of rib graft and serratus anterior muscle. This medical abstract presents a case study of a 52-year-old male with a history of heavy smoking and obliterating arteriopathy of the lower limbs. The patient sustained a traumatic open fracture classified as Type IIIA Gustilo Anderson involving one-third of the distal right tibia diaphysis, with an associated right fibular malleolus fracture. The treatment approach comprised multiple stages, focusing on wound management, infection control, and limb salvage. The initial stage involved the application of an external fixation device in the emergency setting. Seven days later, an osteosynthesis procedure was performed using a Kuntscher nail and wire cerclage. However, complications emerged, with wound dehiscence and purulent secretion observed at 14 days postsurgery. Subsequently, secondary suturing was carried out at the 20-day mark. The second stage of the treatment involved implant removal, wide excisional debridement, pulse lavage, osteoclasia, and relaxation of the peroneal malleolus. A monoplane external fixation system was applied. As a part of postoperative care, aspiration therapy with a vacuum pump was administered, along with a 10-day course of vancomycin according to the antibiogram. Positive clinical signs of healing were noted, and sterile cultures confirmed the results. The third stage of the intervention focused on grafting the osteo-muscular defect, utilizing autografts from the rib and serratus anterior muscle. The external fixator was maintained in place during this phase. In the fourth and final stage, after an 8-week integration period of the musculocutaneous flap, the external fixator was removed, and internal fixation was accomplished with a blocked Less Invasive Stabilization System (LISS) plate inserted using the Minimally Invasive Plate Osteosynthesis (MIPO) technique. This case underscores the significance of a multistage approach in managing complex limb injuries, emphasizing the importance of timely intervention, infection control, and innovative techniques for limb salvage and restoration of function.

Deliberately Staged Combined Endovascular Embolization and Subsequent Microsurgery Resection for the Treatment of Cerebral Arteriovenous Malformations.

OBJECTIVE: Complex cerebral arteriovenous malformations (AVMs) require a combined therapy of endovascular embolization and microsurgical resection to eliminate the lesion and maximize neurological protection, while a deliberate time interval might contribute to optimal clinical outcomes. The present study aimed to explore the feasibility of this paradigm. METHODS: All patients who underwent deliberately planned presurgery embolization and microsurgery resection between 2015 and 2023 were reviewed, with baseline data, postoperative complications, and follow-up outcomes recorded. The modified Rankin scale (mRS) was used to evaluate clinical outcomes, with mRS 0-2 defined as good. RESULTS: A total of 30 patients were included in the study (15 were ruptured AVMs). The median Spetzler-Martin grade of baseline AVMs was 3 (interquartile range: 2-3). The median interval between the last embolization and microsurgery was 5 days (interquartile range: 2.25-7). The complete removal rate was 100%, and the overall permanent complication rate was 16.67%. At the last follow-up, 26 patients achieved mRS 0-2, while 28 had improved or unaltered mRS. The last follow-up mRS significantly improved from baseline and discharge (P = 0.0006 and P = 0.006). The last follow-up mRS decreased by 0.65 for each additional day of time interval before the 4.4-day inflection point (ß = -0.65, P = 0.02) in the AVM ruptured cohort. CONCLUSIONS: The deliberately staged combined procedure of embolization and microsurgery might be a safe and efficacious strategy for Spetzler-Martin grade 2-5 AVMs, 4-5 days might be an appropriate staged time interval for ruptured AVMs, although further studies are needed to substantiate these findings.

Perioperative Impact of Early Limited Surgical Intervention to Treat Pilon Fractures.

BACKGROUND: The operative treatment of pilon fractures is classically treated with a staged protocol with ankle spanning external fixator, followed by definitive open reduction and internal fixation in order to decrease risk of soft tissue complications and infection. However, treatment of pilon fractures with patrial tibial fixation in addition to ankle spanning external fixation at the time of index procedure may facilitate final fixation while avoiding complications that were associated with acute definitive fixation. METHODS: Retrospective cohort series of 113 patients treated for pilon fractures from September 2012 to November 2018 at a single level 1 trauma center. Charts were reviewed to compare patients who underwent traditional management with a staged protocol and those who had a limited tibial reduction and fixation (LTRF) during the index procedure. The main outcome measurement was time to definitive fixation. RESULTS: Twenty-six percent of patients (29 of 113) had limited tibial reduction and fixation (LTRF) during index surgery. Mean time between index procedure and definitive ORIF was 4.75 days less for LTRF cohort compared to standard stage cohort (10.86 ± 7.44 vs. 15.61 ± 8.59 days, P = .009). The index procedure took on average 51 minutes longer in the LTRF cohort (P < .001), yet definitive procedure operative time was decreased by an average of 98 minutes (P < .001), and overall (index plus definitive) operative duration was shortened by an average of 50 minutes (P = .044). There was no difference in rate of infection between LTRF (3.1%) and traditional treatment (2.5%) (P = .86) or reduction quality (P = .270). There were no nonunions in either treatment group. CONCLUSION: Patients who had LTRF had quicker time to definitive ORIF and decreased operative time for definitive ORIF. There was no difference in infection rate, reduction quality, or nonunion rate between groups. LEVEL OF EVIDENCE: Level IV, Retrospective Cohort Study.

Staged treatment for ruptured wide-neck intracranial aneurysm with intentional partial coiling in the acute phase followed by definitive treatment.

Background: Evidence supports endovascular coiling for ruptured intracranial aneurysms (RIAs). However, in some cases, it is difficult to achieve complete occlusion by coiling, such as with wide-neck aneurysms. We report our experience with intentional staged RIA treatment using targeted endovascular coiling at the rupture point in the acute phase, followed by delayed stent-assisted coiling, flow diverter stenting, or surgical clipping. Methods: Consecutive patients with RIAs treated between April 2015 and June 2021 were retrospectively investigated. Clinical characteristics, treatment complications, and patient outcomes data were collected. Results: Among 108 RIAs treated in our hospital, 60 patients underwent initial coiling; 10 patients underwent staged treatment. The aneurysm locations were the anterior communicating artery (n = 5), internal carotid-posterior communicating artery (n = 3), internal carotid-paraclinoid (n = 1), and vertebral artery-posterior inferior cerebellar artery (n = 1). The mean ± standard deviation aneurysmal diameter was 9.6 ± 5.4 mm and the mean aspect ratio was 1.2 ± 0.7. As the second treatment to obliterate blood flow to the neck area, we performed five stent-assisted coiling, two flow-diverter stentings, and three surgical clippings. Only one minor perioperative complication occurred. The median duration between the first and second treatments was 18 days (range, 14- 42 days). Good clinical outcome (modified Rankin scale score 0-2) at 90 days was achieved in 5 (50%) cases. The median follow-up duration was 6.5 months (range, 3-35 months); no rerupture occurred. Conclusion: Intentional staged treatment with a short time interval for RIA was effective and feasible.

Temporary external fixation versus direct ORIF in complete displaced intra-articular radius fractures: a prospective comparative study.

PURPOSE: In complex distal radius fractures (DRF), both direct osteosynthesis (one-stage approach) and temporary external fixation as a bridge to definitive osteosynthesis (two-stage approach) are used. Studies directly comparing these two management options are lacking. This study aims to compare the two procedures with regard to complications, and radiological and functional outcomes. MATERIAL: This prospective observational study included all patients presenting with AO OTA C2 or C3 DRF (1) between January 2011 and January 2018. All patients were categorised into two groups according to received treatment: patients who underwent direct definitive osteosynthesis (Group One Stage) and patients who received an external fixator followed by definitive fixation (Group Two Stage). Primary outcome was the Patient-Rated Wrist Evaluation score (PRWE) measured at 1 year follow-up. Secondary outcomes included complications, range of motion (ROM), and radiologic parameters (ulnar variance, radial inclination and volar tilt). RESULTS: A total of 187 patients were included in Group One Stage with a mean age of 55.6 years (SD 17.2), of which 67 had a C2 and 120 a C3 fracture. Group Two Stage consisted of 66 patients with a mean age of 53.7 years (SD 20.4 years), of which 6 patients having a C2 and 60 a C3 fracture. There was no significant difference in complications and median PRWE between Group One Stage (12.0, IQR 2.0-20.0) and Group Two Stage (12.2, IQR 5.5-23.4) (p = 0.189), even after correction for differences in baseline characteristics. The ROM and radiologic parameters did not show any significant differences as well. CONCLUSION: No differences were found in clinical, functional, and radiological outcome between one- and two-staged surgical techniques. It may be concluded that a two-stage approach is a viable and safe alternative.

Staged Management of Severely Displaced Calcaneal Fractures With Transarticular Pinning: A Damage Control Strategy.

BACKGROUND: Severely displaced calcaneal fractures can result in considerable morphology derangement and may be accompanied by soft tissue compromise. Delayed operative restoration of the calcaneal morphology may result in acute retensioning of the damaged soft tissue with associated wound-related complications. In this study, we describe a staged treatment of displaced intra-articular calcaneal fractures that uses temporary transarticular Kirschner wire (K-wire) fixation and staged conversion to definite fixation. METHODS: We identified all of the patients who were treated at our institution for calcaneal fractures between 2015 and 2019. A total of 17 patients with 20 calcaneal fractures were selectively treated with 2-stage management. Temporary transarticular K-wire fixation was performed 24 hours after the injury to restore calcaneal morphology and the surrounding soft tissue. After the soft tissue was considered safe, delayed open reduction and internal fixation was performed. The time to definite surgery, radiographic alignment, wound complications, time to radiographic union, and hindfoot American Orthopaedic Foot & Ankle Society (AOFAS) scores were recorded. RESULTS: The average follow-up period was 17 months (range, 12-43). The average Böhler angle increased from a mean of -22 degrees (range, -109 to 25) to 25 degrees (range, 0 to 47) after temporary transarticular K-wire fixation. The mean time from temporary pinning to conversion to definite internal fixation was 20 (range, 10-32) days. There were no immediate postoperative complications. The average time to radiographic union was 13.7 (range, 10-16) weeks. The mean AOFAS score was 87 (range, 55-100). No infections or wound complications were reported during the follow-up period. CONCLUSION: Temporary transarticular pinning for staged calcaneal fracture treatment is safe and effective in restoring the calcaneal morphology. This novel and relatively simple method may facilitate delayed operation and decrease wound-related complications. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Is the proximity of external fixator pins to eventual definitive fixation implants related to the risk of deep infection in the staged management of tibial pilon fractures?

INTRODUCTION: In the staged management of tibial pilon fractures, overlap between definitive internal fixation and external fixation pin sites has been investigated as a risk factor for infection with equivocal conclusions. Our aim was to determine if overlap or proximity of definitive internal fixation to external fixation pin sites influences the risk of deep infection. PATIENTS AND METHODS: We reviewed 280 AO/OTA 43B or 43C type distal tibia fractures in 277 patients at two level-one trauma centers. Patients underwent staged management using early temporizing external fixation followed by definitive open reduction and plate fixation. Primary outcome was the association between pin site overlap and the development of deep infection. Secondary outcome was the relationship between development of deep infection and the distance from pin site to definitive fixation. RESULTS: The average duration between external fixation and definitive internal fixation was 14 days. 24% of fractures developed deep infection requiring surgical intervention. There was no association between pin site overlap and the development of deep infection (p = 0.18). There was no relationship between infection and the distance between proximal plate extent and pin site (p = 0.13). DISCUSSION: We identified no association between pin site overlap and the development of deep infection. We suggest that temporizing external fixation pins should be placed so as to obtain optimal stability of the construct with lesser emphasis on aiming to be absolutely outside the zone of future fixation.
