Incidence and risk factors for shoulder stiffness after open and arthroscopic rotator cuff repair.

INTRODUCTION: The aim of this study was to estimate the incidence of stiffness during the first 6 months after rotator cuff repair and to evaluate postoperative stiffness with respect to its risk factors and its influence on the outcome at 6 months postoperatively. METHODS: In a prospective cohort of 117 patients (69 women, 48 men; average age 59) from our institutional rotator cuff registry, who underwent either arthroscopic (n = 77) or open (n = 40) rotator cuff repair, we measured shoulder range of motion (ROM) at 3 and 6 months post-surgery. We evaluated the incidence of stiffness and analyzed functional outcomes, comparing various preoperative and intraoperative factors in patients with stiffness to those without at the 6-month mark. RESULTS: Shoulder stiffness was observed in 31% of patients (36/117) at 3 months postoperatively, decreasing to 20% (23/117) at 6 months. No significant link was found between stiffness at 6 months and demographic factors, preoperative stiffness, tear characteristics, or the type of repair. Notably, patients undergoing arthroscopic repair exhibited a 4.3-fold higher risk (OR 4.3; 95% CI 1.2-15.6, p = 0.02) of developing stiffness at 6 months compared to those with mini-open repair. Despite these differences in stiffness rates, no significant variation was seen in the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, or Visual Analog Scale (VAS) scores at 6 months between the groups. CONCLUSION: The incidence of postoperative shoulder stiffness following rotator cuff repair was substantial at 31% at 3 months, reducing to 20% by 6 months. Mini-open repair was associated with a lower 6-month stiffness incidence than arthroscopic repair, likely due to variations in rehabilitation protocols. However, the presence of stiffness at 6 months post-surgery did not significantly affect functional outcomes or pain levels.

[Translated article] Postsurgical analgesic efficacy by the intra-articular administration of ropivacaine with dexmedetomidine versus simple ropivacaine in patients undergoing knee arthroscopy.

The effective relief of postsurgical pain in patients undergoing knee arthroscopy is important to allow the initiation of activities of daily living. The objective of this study is to demonstrate the analgesic efficacy of dexmedetomidine as an adjuvant added to ropivacaine by the intra-articular route. METHOD: Seventy patients underwent knee arthroscopy which were randomly assigned into two groups (n=35). The RD group received ropivacaine 1.5mg/kg plus dexmedetomidine 1µg/kg intra-articularly. Group R received ropivacaine 1.5mg/kg intra-articularly. The analgesic effect was evaluated by measuring the intensity of pain (VAS score) and the duration of analgesia. RESULTS: A longer duration of the analgesic effect was observed in the RD group (655min) compared to the R group (318min) being statistically significant (p=0.03). CONCLUSION: Dexmedetomidine as an adjuvant to intra-articular ropivacaine improves the quality and duration of postoperative analgesia in patients undergoing knee arthroscopy.

Clinical and demographic factors associated with the effectiveness of temporomandibular joint arthroscopy.

PURPOSE: High success rates and minimal complications have consolidated arthroscopy as the therapeutic alternative of choice for minimally invasive treatment of internal disorders (ID) of the temporomandibular joint (TMJ). However, there is no certainty regarding the demographic and clinical factors associated with the technique's success or failure. This study was performed to analyze the effectiveness of arthroscopy regarding pain and the mandibular dynamics and also to determine whether variables such as age, sex, and preoperative Wilkes stage influence the results. METHODS: A retrospective study was conducted involving 92 patients with ID of the TMJ between September 2017 and February 2020. In all cases, a first stage of intra-articular lysis and lavage was executed. As needed, a phase of operative arthroscopy or arthroscopic discopexy was implemented. RESULTS: A total of 152 arthroscopies were performed. Both the variation in pain and mouth opening in patients with ID of the TMJ treated were statistically significant for the follow-up periods studied. Better results were observed for patients with lower Wilkes stages. No association with age was found. CONCLUSION: Based on the results, we recommend early intervention as soon as an ID in the TMJ is detected.

Arthroscopic Needling Technique for the Treatment of Wrist Ganglia.

Background Synovial cysts (SCs) are the most frequent wrist tumors; the arthroscopic treatment presents good results when surgery is indicated for symptomatic or patients with cosmetic concerns. The tumoral lesion should be arthroscopically decompressed or drained toward the inside of the joint through pedicle opening and resection of a small portion of the capsule. Hence, the cyst pedicle must be found for the success of this technique. Description of Technique Some tricks have already been described to facilitate SC location during arthroscopy. We describe an indirect technique that employs an 18-G needle to enhance SC pedicle location and drainage. The technique involves a puncture on the interval of the carpal extrinsic ligaments where the pedicle is suspected to be remain. When found, cyst is drained with a single-puncture motion of the need which promotes cyst content extravasation due to pressure toward the joint. Patients and Methods This method has been employed in 16 patients, including 9 with dorsal cysts, and seven with volar cysts. Results All patients presented complete recovery and symptom improvement in up to 30 days, with total disappearance of the cyst. There were no relapses or severe complications within the 12-month follow-up. Conclusion This is a safe, useful technique that facilitates location of intra-articular cyst pedicle, thus avoiding unnecessary damage in healthy tissues with no increased costs.

THE OUTCOMES OF POSTERIOR CRUCIATE LIGAMENT TIBIAL AVULSION FIXATION WITH A SCREW USING A DUAL POSTEROMEDIAL PORTAL TECHNIQUE.

Objectives: Our purpose was to evaluate the clinical results of PCL tibial avulsion fracture fixation performed with 4 mm cancellous screws using a dual posteromedial (PM) portal technique. Methods: In a prospective study, we followed 12 patients submitted to PCL tibial insertion avulsion arthroscopic fixation using dual PM portals with cancellous screws from March 2014 to Jan 2020. The proximal higher PM portal served as an instrument portal and provided an optimal trajectory for arthroscopic screw fixation of larger PCL avulsion fractures. The lower PM portal was used as a viewing portal. Results: Significant improvements were found between the preoperative and postoperative mean Lysholm scores at six months. The preoperative IKDC score mean of 10.13 increased to 89.3 at the end of six months. Minor adverse results with this technique were: grade I on posterior sag in five knees (41.6%), temporary stiffness in two cases (16.7 %), delayed union in one patient (8.3 %), and difficulty squatting at the end of six months in one patient (8.3%). Temporary extension lag was present in two individuals (16.7%), and fixed subtle flexion deficit of 3-5 degrees occurred in one individual (8.3 %). Conclusion: The outcomes obtained with the proposed technique were similar to those obtained with open techniques, although mild flexion deficits and discreet posterior sag may be present in a significant number of cases. Level of Evidence II; Prospective Cohort Study .

Fluid preloading before beach chair positioning for arthroscopic shoulder procedures: a randomized controlled trial

Abstract Background and objectives The Beach Chair Position (BCP) has many advantages such as less neurovascular injury and better intra-articular visualization, but it has also negative consequences, including hemodynamic instability. Although maintaining normal Mean Arterial Pressure (MAP) is important, fluid management is also a crucial concept for hemodynamic stability. The main objective of this study is whether preloading before positioning would be effective for less hemodynamic instability. Methods This randomized, controlled study was conducted in a single center in the Istanbul University, Istanbul Faculty of Medicine. Forty-nine patients undergoing elective arthroscopic surgery in the BCP were recruited. In the study group, crystalloid fluid at 10 mL.kg-1 of ideal body weight was administered intravenously 30 min before the BCP for preloading. The primary outcome measures were differences of hemodynamic variables as MAP, Stroke Volume (SV), Heart Rate (HR), and Cardiac Output (CO). The secondary outcome measures were Postoperative Nausea and Vomiting (PONV) rates in postoperative first day, surgical satisfaction scale, total ephedrine dose used during surgery, and total amount of fluid. Results The MAP, CO, and SV measurements of the study group were higher than those of the control group in the 5th minute after the BCP (respectively, p= 0.001, p= 0.016, p= 0.01). The total amount of crystalloid and surgical satisfaction scales were higher in the study group (respectively, p= 0.016, p= 0.001). Total amount of colloid and ephedrine dose used in the intraoperative period, and PONV rates were lower in the study group (p= 0.003, p= 0.018, p= 0.019, respectively). Conclusion Consequently, preloading can be favorable approach to preserve hemodynamic stability.

Relationship of the SIRSI Score to Return to Sports After Surgical Stabilization of Glenohumeral Instability.

BACKGROUND: Literature is scarce regarding the influence of psychological readiness on return to sports after shoulder instability surgery. PURPOSE: To evaluate the predictive ability of the Shoulder Instability-Return to Sport after Injury (SIRSI) score in measuring the effect of psychological readiness on return to sports and to compare it between athletes who returned to sports and athletes who did not return to sports. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A prospective analysis was performed of patients who underwent an arthroscopic Bankart repair or a Latarjet procedure between January 2019 and September 2020. Psychological readiness to return to play was evaluated using the SIRSI instrument. Preoperative and postoperative functional outcomes were measured by the Rowe, Athletic Shoulder Outcome Scoring System, and Western Ontario Shoulder Instability Index scores. The predictive validity of the SIRSI was assessed by the use of receiver operating characteristic (ROC) curve statistics. The Youden index was calculated and used to determine a SIRSI score cutoff point that best discriminated psychological readiness to return to sports. A logistic regression analysis was performed to evaluate the effect of psychological readiness on return to sports and return to preinjury sports level. RESULTS: A total of 104 patients were included in this study. Overall, 79% returned to sports. The SIRSI had excellent predictive ability for return-to-sport outcomes (return to sports: area under ROC curve, 0.87 [95% CI, 0.80-0.93]; return to preinjury sports level: area under ROC curve, 0.96; [95% CI, 0.8-0.9]). A cutoff level of ≥55 was used to determine whether an athlete was psychologically ready to return to sports and to return to preinjury sports level (Youden index, 0.7 and 0.9, respectively). Of those who returned to sports, 76.8% were psychologically ready to return to play, with a median SIRSI score of 65 (interquartile range, 57-80). In comparison, in the group that did not return to sports, only 4.5% achieved psychological readiness with a median SIRSI score of 38.5 (interquartile range, 35-41) (P < .001). Regression analysis for the effect of SIRSI score on return to sports was performed. For every 10-point increase in the SIRSI score, the odds of returning to sports increased by 2.9 times. Moreover, those who did not achieve their preinjury sports level showed poorer psychological readiness to return to play and SIRSI score results. CONCLUSION: The SIRSI was a useful tool for predicting whether patients were psychologically ready to return to sports after glenohumeral stabilization surgery. Patients who returned to sports and those who returned to their preinjury sports level were significantly more psychologically ready than those who did not return. Therefore, we believe that the SIRSI score should be considered along with other criteria that are used to decide whether the patient is ready to return to sports.

Return to sports, functional outcomes, and recurrences after arthroscopic Bankart repair in soccer players.

Background: There is a shortage of relevant reports about the results obtained after shoulder stabilization in soccer players. Therefore, this retrospective study aims to report return to sports, functional outcomes, and recurrences after arthroscopic Bankart repair in soccer players. Methods: A total of 156 soccer players were treated for anterior shoulder instability at a single institution between 2008 and 2017. The Rowe score and Athletic Shoulder Outcome Scoring System were used to assess functional outcomes. Return to sport and recurrence rates were also evaluated. Results: The Rowe and Athletic Shoulder Outcome Scoring System scores showed statistical improvement after surgery (P < .001). Overall, 148 soccer players (94.8%) returned to sports, and 122 (78.2%) returned to the same level. The mean time to return to sport was 4.8 months. The recurrence rate was 5.2%. Discussion: Soccer players who underwent an arthroscopic isolated Bankart repair for anterior glenohumeral instability have shown remarkable outcomes, with most of the patients returning to sports, and at the same level they had before surgery with a low rate of recurrence.

The playing position significantly influences return to sports and recurrences after an arthroscopic Bankart repair in competitive rugby players.

Background: The purpose of our study was to investigate the influence of the different rugby playing positions on return to sports, functional outcomes, and recurrences after an arthroscopic Bankart repair. Methods: A total of 88 rugby players were treated for anterior shoulder instability in our institution between 2010 and 2018. Functional outcomes, return to sports, recurrences, complications, and revisions rates were evaluated according to the playing position. Results: Overall, 73.8% of the patients returned to rugby and 60% returned at the same level as before the injury. The tight forwards and outside backs experienced a significant decrease in their competitive level after surgery, and showed the lowest functional outcomes. The tight forwards and outside backs showed a statistically significant increase in recurrence and revision rates, and an OR for recurrence of 12.8 and 9.6, respectively. Discussion: The playing position significantly influenced return to sports and recurrences after an arthroscopic Bankart repair in competitive rugby players. Specifically, the tight forwards and outside backs have returned to a lower level than they had before surgery, showed the lowest functional outcomes, and a significant increase in recurrences and revisions rates than the other groups.

Treatment of Severe Rigid Posttraumatic Equinus Deformity With Gradual Deformity Correction and Arthroscopic Ankle Arthrodesis.

BACKGROUND: Posttraumatic ankle equinus is associated with rigid deformity, poor skin condition, and multiple prior surgeries. Open acute correction has been described using osteotomies, talectomy, and arthrodesis, but concerns exist about skin complications, neurologic alterations, secondary limb discrepancy, and bone loss. Gradual correction using a multiplanar ring fixator and arthroscopic ankle arthrodesis (AAA) may decrease these complications. METHODS: We retrospectively reviewed patients undergoing correction of posttraumatic rigid equinus with at least 1 year of follow-up after frame removal. The procedure consisted of percutaneous Achilles lengthening, gradual equinus correction using a multiplanar ring fixator, and AAA retaining the fixator in compression with screw augmentation. Frame removal depended on signs of union on the computed tomography scan. Visual analog scale (VAS) and Foot Function Index (FFI) scores were assessed as well as preoperative and postoperative x-rays. Complications were noted throughout the follow-up period. RESULTS: Five patients were treated with a mean age of 35 years and mean follow-up of 31 months. Deformities were gradually corrected into a plantigrade foot over an average duration of 6 weeks. Union was achieved in all patients with a mean time of an additional 25 weeks, for a mean total frame time of 31 weeks. The mean preoperative tibiotalar angle was 151 degrees and was corrected to 115 degrees. FFI score improved from a mean of 87 to 24 and VAS from 8 to 2. CONCLUSION: Posttraumatic rigid equinus can be treated effectively using gradual correction followed by integrated AAA in a safe and reproducible manner. Patients in this series had excellent functional, radiological, and satisfaction results. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Clinical Relevance of Persistent Off-Track Hill-Sachs Lesion After Arthroscopic Latarjet Procedure.

BACKGROUND: The Latarjet procedure is often used to address off-track Hill-Sachs lesions (OFF-HS) in shoulders with anterior instability. There are concerns as to whether the Latarjet procedure is able to convert all OFF-HS into on-track Hill-Sachs lesions (ON-HS) and whether this limitation could explain the cases of recurrent postoperative instability. HYPOTHESIS: Latarjet surgery converts many preoperative OFF-HS lesions, but not all of them, and there is a difference in the failure rate between shoulders with converted lesions and those with persistent OFF-HS lesions. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients with anterior shoulder instability and an OFF-HS lesion treated with an arthroscopic classic Latarjet procedure between January 2010 and September 2017 were retrospectively evaluated. Patients with moderate or severe shoulder arthrosis, rotator cuff tears, or age older than 50 years were excluded. Glenoid track (GT), HS, HS interval (HSI), and the difference between HSI and GT (ΔHSI-GT) were measured preoperatively. A postoperative computed tomography scan and a clinical evaluation, including the Rowe and Western Ontario Shoulder Instability scores, were performed at a minimum 1- and 2-year follow-up, respectively. Postoperatively, 2 groups of patients were obtained: (1) patients with postoperative persistent OFF-HS; (2) patients with postoperative ON-HS. Clinical and imaging data were compared between the 2 groups. RESULTS: A total of 51 patients (n = 51 shoulders), with a mean age of 29.8 ± 8.4 years (range, 15-50 years), met the inclusion criteria. Six shoulders (11.8%) still showed OFF-HS lesions despite Latarjet surgery. There were no postoperative dislocations, but 3 patients reported subluxations. The subluxation rate was significantly higher in the postoperative persistent OFF-HS group (2 [33%] vs 1 [2.2%]; P = .033). There was a wider preoperative HSI (29.8 ± 2.4 mm vs 22.9 ± 3.5 mm; P < .001) and a larger preoperative ΔHSI-GT (12.2 ± 3.8 mm vs 4.82 ± 3.2 mm; P < .001) in the persistent OFF-HS group. A receiver operating characteristic curve was performed based on preoperative ΔHSI-GT values. A preoperative ΔHSI-GT value ≥7.45 mm predicted a persistent OFF-HS after Latarjet surgery (sensitivity, 100%; specificity, 87%; positive predictive value, 50%; and negative predictive value, 100%). CONCLUSION: Latarjet surgery converted many preoperative OFF-HS lesions into ON-HS lesions, but not all of them. Six patients (11.8%) retained an OFF-HS and had a statistically significantly higher failure rate after Latarjet surgery compared with those with postoperative ON-HS lesions. Because there were few postoperative OFF-HS lesions and few recurrences, findings are statistically fragile and should be confirmed with larger series.

A rare case of pulmonary embolus after arthroscopic meniscus surgery.

Although there is consensus that thromboprophylaxis is necessary for major orthopedic surgeries such a joint replacement, there is no widespread consensus on the need for thromboprophylaxis for minor arthroscopic surgery. Here, we present a case of deep vein thrombosis (DVT) and pulmonary embolism (PE) after a common arthroscopic meniscectomy in a healthy 20-year-old female collegiate athlete. The patient had no risk factors except for prior use of combined oral contraceptive pills (COCPs). Twenty hours after an uncomplicated right knee meniscectomy, patient presented to ED with right calf pain and cramping, and DVT was confirmed using ultrasound. One week later, patient presented again to ED with dyspnea and chest pain. PE was diagnosed on CT angiography. Despite the rarity of thromboembolic complications in minor arthroscopy surgery, the broadened use of thromboprophylaxis in patients with even few risk factors could prevent thromboembolic complications from occurring.

Intra-abdominal Fluid Extravasation: Is Endoscopic Deep Gluteal Space Exploration a Risk Factor?

BACKGROUND: The extravasation of fluid into the intra-abdominal space is recognized as a possible complication of hip arthroscopic surgery/endoscopy. The exposure of anatomic areas to elevated pump pressures and high volumes of irrigation fluid increases the risk of fluid leakage into anatomic spaces around the hip joint, especially to the abdomen and pelvis. PURPOSE: To estimate the incidence and risk factors related to intra-abdominal fluid extravasation (IAFE) after hip endoscopy or arthroscopic surgery. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A prospective study was carried out between June 2017 and June 2018. A total of 106 hip procedures (endoscopy or arthroscopic surgery) performed for extra- or intra-articular abnormalities were included. Before and after surgery, in the operating room, ultrasound was performed by a trained anesthesiologist to detect IAFE. The hepatorenal (Morison pouch), splenorenal, retroaortic, suprapubic (longitudinal and transverse), and pleural spaces were examined. Patients were monitored for 3 hours after surgery to assess for abdominal pain. The data collected included maximum pump pressure, duration and volume of irrigation fluid (Ringer lactate), total surgical time, and traction time. RESULTS: The incidence of IAFE was 31.1% (33/106; 95% CI, 23.1%-40.5%). The frequency of IAFE was 52.9% (9/17) in cases with isolated extra-articular abnormalities and 15.9% (7/44) in cases with isolated femoroacetabular impingement; in cases with both extra- and intra-articular abnormalities, the frequency was 37.8% (17/45). An intervention in the subgluteal space was identified as a risk factor for IAFE (odds ratio, 3.62 [95% CI, 1.47-8.85]). There was no statistically significant difference between groups (with vs without IAFE) regarding total surgical time, maximum pump pressure, or fluid volume. Postoperative abdominal pain was found in 36.4% (n = 12) of cases with IAFE compared with 2.7% (n = 2) of cases without extravasation (P < .001). No patient with IAFE developed abdominal compartment syndrome. CONCLUSION: IAFE was a frequent finding after hip arthroscopic surgery/endoscopy in patients with extra-articular abnormalities. Exploration of the subgluteal space may increase the risk of IAFE. Pain and abdominal distension during the immediate postoperative period were early warning signs for IAFE. These results reinforce the need for careful intraoperative and postoperative monitoring by the surgeon and anesthesiologist to identify and avoid complications related to IAFE.

Radiographic displacement of acute acromioclavicular joint dislocations fixed with AC TightRope.

BACKGROUND: The arthroscopic approach to acromioclavicular (AC) dislocation with methods such as AC TightRope fixation has reported radiographic failure rates between 18% and 50% with functional results graded as good or excellent. Our objective was to review the outcomes after arthroscopic fixation for acute AC joint dislocation using the TightRope device. METHODS: We reviewed the records of 52 patients, with a mean age of 31 years, who underwent arthroscopic fixation with the TightRope device for acute AC joint dislocation. Outcomes were evaluated using the Constant and University of California, Los Angeles scores. The coracoclavicular (CC) distance before and after surgery was compared by radiography. RESULTS: The mean follow-up period was 36.7 months (range, 6-65 months). Postoperatively, the mean Constant score was 97.13 and the mean University of California, Los Angeles score was 33.2. The CC distance was maintained in 73% of the patients, whereas partial loss of reduction occurred in 19.2% and failure of reduction occurred in 7.7%. CONCLUSION: Arthroscopic fixation using the TightRope device for acute AC joint dislocation achieves satisfactory clinical outcomes. However, CC reconstruction appears to result in subluxation in cases with AC dislocation for a period of more than 10 days.

Artroscopía de rodilla bajo bloqueos de nervios femoral y ciático en paciente COVID-19 con artritis séptica. Reporte de caso / Knee arthroscopy under femoral and sciatic nerve blocks in a COVID-19 patient with septic arthritis. A case report

Since the start of the COVID-19 pandemic, several anesthetic societies have generated clinical recommendations for the perioperative management of these patients, including the Chilean Society of Anesthesiology. Among these recommendations, the advantages of regional anesthesia have been highlighted. In this article, we report and discuss the case of a 59-year-old patient with diabetes mellitus II, Chronic Arterial Hypertension, Gout, and Stage IV Chronic Renal Failure admitted with a multifocal septic condition characterized by suppurative collections including a large subcutaneous lumbar abscess recently drained. The patient evolved with left knee septic arthritis and was scheduled for arthroscopic irrigation and debridement. As per protocol a SARS-COV2 PCR was tested and resulted positive. It was decided to proceed to surgery under anesthetic ultrasound-guided femoral and sciatic nerve blocks using an adrenalized (2.5 ug/mL) solution of 0.33% Levobupivacaine- 0.66% Lidocaine (15 mL each). Fifteen minutes later, the knee was mobilized passively without pain. Surgery started after 30 minutes. The surgical and anesthetic conditions were described as adequate by the surgeon and the patient, respectively. The postoperative evolution was satisfactory without presenting respiratory symptoms and the patient was discharged 17 days after under oral antibiotic treatment.

Desde el comienzo de la pandemia de COviD-19, varias sociedades de anestesia han generado recomendaciones clínicas para el tratamiento perioperatorio de estos pacientes, incluida la Sociedad Chilena de Anestesiología. Entre estas recomendaciones, se han destacado las ventajas de la anestesia regional. En este artículo, reportamos y discutimos el caso de un paciente de 59 años con diabetes mellitus tipo 2, hipertensión arterial, gota e insuficiencia renal crónica en etapa IV, admitido por una sepsis multifocal caracterizada por colecciones supurativas que incluyen un gran absceso lumbar subcutáneo drenado recientemente. El paciente evolucionó con artritis séptica de rodilla requiriendo de una exploración y aseo artroscópico. Por protocolo perioperatorio COviD-19, se solicitó PCR para SARS-COv2 con un resultado positivo. Se decidió proceder a la cirugía bajo bloqueos anestésicos guiados por ultrasonido de nervios femoral y ciático utilizando una solución adrenalizada (2,5 ug/mL) de levobupivacaína al 0,33% lidocaína al 0,66% (15 mL en cada uno). Quince minutos después, la rodilla se movilizó pasivamente sin dolor. La cirugía se inició tras media hora empleando una ligera sedación con propofol. Las condiciones quirúrgicas y anestésicas fueron descritas como adecuadas por el cirujano y el paciente. Este último evolucionó favorablemente, sin síntomas respiratorios y fue dado de alta 17 días después con tratamiento antibiótico oral.
