RETRACTION: Open reduction internal fixation versus minimally invasive percutaneous fixation for calcaneus fractures: Mid-term outcomes and social consequences

Objectives: This study aims to evaluate the mid-term clinical, functional, radiological, and socioeconomic outcomes of calcaneus fractures treated with open reduction-internal fixation (ORIF) versus minimally invasive percutaneous fixation (MIPF). Patients and methods: A total of 48 patients (34 males, 14 females; mean age: 44.05 years; range, 19 to 64 years) who underwent either ORIF or MIPF for calcaneus fractures between January 2010 and January 2016 were retrospectively analyzed. The patients were divided into two groups as the ORIF group (n=36) and MIPF group (n=12). The American Orthopaedic Foot & Ankle Society (AOFAS) score, Maryland Foot Score (MFS), and the Short Form-36 (SF-36) scores were assessed for the clinical assessment. The mean duration of operation, mean length of hospitalization, pedobarographic gait analysis, the incidence of contralateral knee pain, increased shoe size, and change of profession due to significant heel pain were also evaluated. The Böhler’s angle, Gissane angle, and calcaneal varus were measured for radiological assessment. Results: There was a significant difference in the mean operation time (p=0.001) and length of hospitalization (p=0.001) between the two groups. There was no significant difference between the pre- and postoperative third-year Böhler’s and Gissane angles (p=0.05, p=0.07, p=0.09, respectively). There were no significant differences between the postoperative first-, second-, and third-year AOFAS, MFS, and SF-36 scores (p=0.57, p=0.55 p=0.85, p=0.64, p=0.21, p=0.51, p=0.20, p=0.15, p=0.22, respectively). Thirteen patients in the ORIF group and five patients in the MIPF group changed their job due to significant heel pain. The increased shoe size was correlated with the residual calcaneal varus (p=0.001). Conclusion: Both methods have pros and cons in the treatment of calcaneal fractures. Although MIPF is more advantageous in terms of operation duration and length of hospitalization, more favorable radiological results can be obtained with ORIF. Calcaneal varus should be corrected to prevent the increased shoe size and contralateral knee pain.

Introduction Although it is not a new technique, minimally invasive direct coronary artery bypass (MIDCAB) is employed only by a few surgeons in the UK. We compared our experience with MIDCAB with that of single vessel off-pump coronary artery bypass (OPCAB) graft surgery through a standard median sternotomy. Methods Patients who underwent either MIDCAB or OPCAB between April 2008 and July 2011 were reviewed. Exclusion criteria included patients with an ejection fraction of <0.5 or previous cardiac surgery. Data were obtained retrospectively from our prospective database, medical records and through general practitioners. Results Overall, 74 patients were analysed in the MIDCAB group and 78 in the OPCAB group. Their demographics and EuroSCORE (European System for Cardiac Operative Risk Evaluation) values were comparable (p>0.05). There was no statistically significant difference in the two groups in terms of mortality, recurrent myocardial infarction, postoperative stroke, wound infection, atrial fibrillation or need for reintervention. The MIDCAB group had six conversions to a sternotomy. Eight patients in each group required blood transfusion, with the average transfusion being 1.8 units in the MIDCAB group and 3.2 units in the OPCAB group. The mean duration of ventilation and intensive care unit stay was 5.0 hours and 38.4 hours in the MIDCAB group and 5.4 and 47.8 hours in the OPCAB group. The mean hospital stay was significantly reduced in the MIDCAB population (6.1 vs 8.5 days, p<0.05). Conclusions MIDCAB can be performed safely in appropriately selected patients with outcomes comparable with OPCAB. The potential benefits include shorter hospital stay, reduced need for blood transfusion and faster recovery.

AbstractBACKGROUNDNumerous minimally invasive approaches to the skull base have been successively developed. Knowledge of the surgical nuances of a specific approach may facilitate approach selection. This study sought to compare the nuances of an extended version of the minipterional craniotomy (EMPT) with those of the transorbital endoscopic approach (TOEA) to the anterior and middle cranial fossae (ACF and MCF, respectively).OBJECTIVETo quantitatively analyze and compare the area of exposure and surgical freedom between EMPT and TOEA to the ACF and MCF.METHODSEMPT and TOEA were carried out in 5 latex-injected cadaveric heads, bilaterally (10 sides). For each approach, the area of exposure, surgical freedom, and angle of attack were obtained with neuronavigation and statistically compared.RESULTSNo significant difference was found between the mean area of exposure of EMPT and TOEA at the ACF and MCF (P = .709 and .317, respectively). The mean exposure area at the ACF was of 13.4 ± 2.6 cm2 (mean ± standard deviation) and 13.0 ± 1.9 cm2 for EMPT and TOEA, respectively. Except for the crista galli, EMPT afforded a larger area of surgical freedom at all targets. EMPT also achieved significantly greater attack angles in vertical axis except to the crista galli. The horizontal attack angles to all targets were similar between approaches.CONCLUSIONEMPT and TOEA offer a comparable area of exposure at the ACF and MCF in the cadaver; however, the instrument maneuverability afforded by EMPT is superior. Further studies are necessary to better define their precise surgical application.

Introduction: Thyroidectomy is a common surgery in the neck area, in which the application of platysma muscle suture after thyroidectomy is still being discussed. This study was conducted to compare the application (currently common) or non-application of suture for platysma muscle. Methods: In this retrospective cross-sectional study, 117 patients underwent thyroidectomy, among which 63 cases without suturing platysma (control group) and 54 subjects with suturing platysma (Intervention group ) were examined in terms of postoperative pain based on visual analogue scale score measured 24 h post-operation. The samples were also investigated regarding hematoma and seroma, wound infection, length of hospitalization, scarring (1 year after surgery), duration of surgery, and the number of cases using opioids during the hospitalization. Patients with diabetes, previous neck surgery, coagulopathy, and radiation history were excluded from the study. The gathered data were analyzed statistically in SPSS software (version 18) using the Chi-square test and the Mann–Whitney U test. A p-value of less than (0.05) was considered significant. Results: Based on the findings, the mean age of the patients in the Intervention group was calculated at 51 years, of which 41 and 13 cases were females and males, respectively. In the Intervention group, 34 patients underwent complete thyroidectomy and 20 patients had hemithyroidectomy. The mean age score of subjects in the control group was calculated at 50 years, of which 44 and 19 patients were respectively female and male. No significant difference was revealed considering wound infection, length of hospitalization, created scarring, the amount of opioid use (opioids), and postoperative pain. However, only the length of surgery was different between the groups (P-value<0.05). Conclusions: There was no difference between wound and surgical complications and cosmetic results between both groups; nevertheless, due to the duration of the surgery and other benefits, such as consuming less thread, not suturing the platysma is recommended.

Background: The minimally invasive chevron-Akin (MICA) osteotomy is an increasingly popular technique for the correction of hallux valgus. However, there is a paucity of literature comparing it with traditional open techniques. The purpose of this study was to compare the clinical and radiological outcomes of the MICA osteotomy using a new-generation MICA screw and scarf-Akin osteotomy for hallux valgus correction. Methods: Thirty cases of MICA osteotomy were propensity score matched 1:1 with a control group of 30 scarf-Akin osteotomy cases. The groups were matched for age, sex, body mass index, preoperative visual analog scale (VAS) score, American Orthopaedic Foot & Ankle Society (AOFAS) metatarsophalangeal-interphalangeal (MTP-IP) score, 36-Item Short-Form Health Survey (SF-36) physical component score (PCS) and mental component score (MCS), preoperative hallux valgus angle (HVA) and intermetatarsal angle (IMA), and concomitant procedures. Outcomes were compared at 6 and 24 months postoperatively. Early postoperative VAS scores were also compared. Results: Both groups demonstrated significant improvements in VAS score, AOFAS score, and SF-36 PCS and MCS at 6 and 24 months postoperatively. For the MICA group, HVA improved from 23.5 to 7.7 degrees, and IMA improved from 13.5 to 7.5 degrees. For the scarf-Akin osteotomy group, HVA improved from 23.7 to 9.3 degrees, and IMA improved from 13.6 to 7.8 degrees. The first 24-hour postoperative VAS score was significantly lower in the MICA group compared with the scarf-Akin group (2.0 ± 2.0 vs 3.4 ± 2.6, P = .029). However, there was no significant difference in clinical or radiological outcomes between the groups at 6 and 24 months. Conclusion: The MICA procedure with the new-generation MICA screw is an attractive option for the correction of hallux valgus, yielding similar midterm radiological and clinical outcomes compared with the well-established scarf-Akin osteotomy. The first 24-hour postoperative VAS score in the MICA group was also statistically lower, although its clinical significance remains to be determined. Level of Evidence: Level III, retrospective comparative study.

Category: Bunion Introduction/Purpose: Minimally invasive surgery for hallux valgus has significantly increased in popularity recently due to smaller incisions, reduced soft tissue trauma, and the ability to achieve large deformity corrections compared to traditional treatments. This study aimed to investigate the radiological outcomes and degree of deformity correction of the intermetatarsal angle (IMA) and the hallux valgus angle (HVA) following third generation (using screw fixation) Minimally Invasive Chevron and Akin Osteotomies (MICA) for hallux valgus. Methods: A single surgeon case series of patients with hallux valgus underwent primary, third generation MICA for hallux valgus. Pre- and post-operative (6 weeks after surgery) radiological assessments of the IMA and HVA were based on weight-bearing dorso-plantar radiographs. Radiographic measurements were conducted by two foot & ankle fellowship trained consultant surgeons (RR, DG). Paired t-tests were used to determine the statistically significant difference between pre- and post-operative measurements. Results: Between January 2017 and December 2019, 401 MICAs were performed in 274 patients. Pre- and post-operative radiograph measurements were collected for 348 feet in 232 patients (219 female; 13 male). The mean age was 54.4 years (range 16.3-84.9, standard deviation (s.d.) 13.2). Mean pre-operative IMA was 15.3° (range 6.5°-27.0°, s.d. 3.4°) and HVA was 33.8° (range 9.3°-63.9°, s.d. 9.7°). Post-operatively, there was a statistically significant improvement in radiological deformity correction; mean IMA was 5.3° (range -1.2°-16.5°, s.d. 2.7°, p<0.001) and mean HVA was 8.8° (range -5.2°-24.0°, s.d. 4.5°, p<0.001). The mean post-operative reduction in IMA and HVA was 10.0° and 25.0° respectively. Conclusion: This is the largest case series demonstrating radiological outcomes following third generation Minimally Invasive Chevron and Akin Osteotomies (MICA) for hallux valgus to date. These data show that this is an effective approach at correcting both mild and severe hallux valgus deformities. Longer term radiological outcome studies are needed to investigate whether there is any change in radiological outcomes. Correlation with patient reported outcomes is planned.

Insertional Achilles Tendinopathy

Background: Insertional Achilles tendinopathy (IAT) is a common cause of chronic posterior heel pain. Surgical intervention reproducibly improves patients’ pain and functional status. We hypothesized that patients older than 60 years would have similar improvements in pain and function and low rates of complications after surgery for IAT when compared to a younger cohort. Methods: Retrospective review of adult case series in patients undergoing surgical management of IAT. Patients were stratified into those 60 years and younger and those older than 60 years. Patients with prior or concomitant surgical procedures and revisions were excluded. Visual analog scale (VAS), Short Form–36 Physical Component Summary and Mental Component Summary (SF-36 PCS/MCS) scores, wound infection, and recurrence, defined as a redevelopment of heel pain in the operative extremity within 6 months, were assessed with a minimum follow-up of 12 months. Statistical analysis was performed using linear regression mixed models and χ2 analysis. Thirty-seven patients were enrolled, with 38 operative heels. The younger cohort had an average age of 49.1 (range, 26-60) years. The older group had an average age of 66.8 (range, 61-76) years. Results: VAS and SF-36 PCS scores for the entire cohort significantly improved at 6 and 12 months postoperatively ( P < .001). Postoperative SF-36 MCS scores for the cohort significantly improved only at 12 months ( P < .001). No significant differences between the young and elderly were seen with regard to improvements in VAS and SF-36 PCS/MCS at 6 or 12 months postoperatively. Multiple linear regression models showed no significant difference between age groups and VAS score, SF-36 PCS/MCS, or change in pain scores after controlling for comorbidities. No significant difference in overall complication rates was seen between the 2 groups (4.9% vs 29.4%, P = .104). There was 1 recurrence of heel pain in the younger group and 4 recurrences of pain in the older group (23.5%) at 6 months, of which 2 resolved at 1 year. There was 1 case of a superficial wound infection requiring antibiotics in the older cohort (5.9%). No patients required surgical revision. Conclusion: Surgical management of IAT in an older population produced similar improvements in clinical results when compared to a younger cohort, with no significant increase in postoperative complications. Level of Evidence: Level III, retrospective comparative series.

Background: Assessing and correcting malalignment is important when treating calcaneus fractures. The Harris axial view is commonly utilized to assess varus deformity but may be inherently inaccurate due to its tangential nature. The anterior-posterior (AP) calcaneal profile view is a novel radiographic view that is easily obtained with demonstrated increased accuracy for assessing calcaneal axial alignment. Methods: Five nonpaired ankle cadaveric specimens were used in this investigation. Oblique osteotomies were created in relation to the long axis, and varus deformities were produced by inserting solid radiolucent wedges into the osteotomies to create models of 10, 20, and 30 degrees of angulation of the calcaneal tuberosity. Specimens were imaged using both the Harris axial view and the AP calcaneal profile view. Results: For cadavers with 10 degrees of actual varus angulation, the mean Harris axial view angle and the AP calcaneal profile view angle were 10.9 ± 4.8 (range, 5.5-16.0) degrees and 13.0 ± 5.5 (range, 7.3-20.9) degrees, respectively. For cadavers with 20 degrees of actual varus angulation, the mean Harris view angle and the AP calcaneal profile view angle were 11.5 ± 2 (range, 8.2-13.6) degrees and 18.1 ± 4.8 (range, 11.7-23.5) degrees, respectively ( P = .005). On pairwise comparison with Bonferroni correction, there was a significant difference between the Harris axial view angle and both the AP calcaneal profile view angle ( P = .012) and actual angulation ( P = .011). For cadavers with 30 degrees of actual varus angulation, the mean Harris axial view angle and the AP calcaneal profile view angle were 18.3 ± 4.3 (range, 13.3-23.6) degrees and 28.3 ± 2.9 (range, 24.4-31.1) degrees, respectively ( P < .001). On pairwise comparison with Bonferroni correction, there was a significant difference between the Harris axial view angle and both the AP calcaneal profile view angle ( P = .001) and actual angulation ( P < .001). There was no significant difference between the AP calcaneal profile view angle and actual angulation ( P > .999). Conclusion: The AP calcaneal profile view is a novel radiographic view that is easily obtained with demonstrated increased accuracy for assessing calcaneal axial alignment. While both views demonstrated similar measurement error for lesser degrees of varus malalignment, the AP calcaneal profile view demonstrated more accurate measurement of increasing heel varus compared with the Harris view. Clinical Relevance: The AP calcaneal profile view could be used in addition to other radiographic views when treating displaced, intra-articular calcaneus fractures to help optimize correction of hindfoot alignment.

Object Multiple surgical procedures have been described for the management of isolated nonsyndromic sagittal synostosis. Minimally invasive techniques have been recently emphasized, but these techniques necessitate the use of an endoscope and postoperative helmeting. The authors assert that a safe and effective, more “minimalistic” approach is possible, avoiding the use of endoscopic visualization and routine postoperative application of a cranial orthosis. Methods A single-institution cohort analysis was performed on 18 cases involving infants treated for isolated nonsyndromic sagittal synostosis between 2008 and 2010 using a nonendoscopic, minimally invasive calvarial vault remodeling (CVR) procedure without postoperative helmeting. The surgical technique is described. Variables analyzed were: age at time of surgery, sex, estimated blood loss (EBL), operative time, intraoperative complications, postoperative complications, length of stay, pre- and postoperative cephalic index (CI), clinical impressions, and results of a 5-question nonstandardized questionnaire administered to patient caregivers regarding outcome. Results Eleven male and 7 female infants (mean age 2.3 months) were included in the study. The mean duration of follow-up was 16.4 months (range 6–38 months). The mean procedural time was 111 minutes (range 44–161 minutes). The mean length of stay was 2.3 days (range 2–3 days). The mean EBL in all 18 patients was 101.4 ml (range 30–475 ml). One patient had significant bone bleeding resulting in an EBL of 475 ml. Excluding this patient, the mean EBL was 79.4 ml (range 30–150 ml). There were no deaths or intraoperative complications; one patient had a superficial wound infection. The mean CI was 69 preoperatively versus 79 postoperatively, a statistically significant difference (p < 0.0001). Two patients were offered helmeting for suboptimal surgical outcome; one family declined and the single helmeted patient showed improvement at 2 months. No patient has undergone further surgery for correction of primary deformity, secondary deformities, or bony irregularities. Complete questionnaire data were available for 14 (78%) of the 18 patients; 86% of the respondents were pleased with the cosmetic outcome, 92% were happy to have avoided helmeting, 72% were doubtful that helmeting would have provided more significant correction, and 86% were doubtful that further surgery would be necessary. Small, palpable, aesthetically insignificant skull irregularities were reported by family members in 6 cases (43%). Conclusions The authors present a nonendoscopic, minimally invasive CVR procedure without postoperative helmeting. Their small series demonstrates this to be a safe and efficacious procedure for isolated nonsyndromic sagittal synostosis, with improvements in CI at a mean follow-up of 16.1 months, commensurate with other techniques, and with overall high family satisfaction. Use of a CVR cranial orthosis in a delayed fashion can be effective for the infrequent patient in whom this approach results in suboptimal correction.

The objective of this study was to explore the effect of minimally invasive puncture drainage under unsupervised learning algorithm and conservative treatment on the prognosis of patients with cerebral hemorrhage. Fifty patients with cerebral hemorrhage were selected as the research objects. The CT images of patients were segmented by unsupervised learning algorithm, and the application value of unsupervised learning algorithm on CT images of patients with cerebral hemorrhage was evaluated. According to the treatment wishes of the patients themselves and their authorizers, they were divided into 30 patients with cerebral hemorrhage in the minimally invasive group and 20 patients with cerebral hemorrhage in the conservative group. The incidence rate of complications of cerebral hemorrhage, the length of hospitalization of the two groups, hematoma volume at admission, 3 days and 7 days after operation, and the hematoma dissipation rate on the 3rd and 7th day after operation were used as the evaluation index of therapeutic effect. MRS and ADL scores were used as prognostic indicators. The results show that K-means clustering algorithm has high quality and short time for CT image segmentation. The overall incidence rate of complications in minimally invasive group was 10%, lower than that in conservative group (25%) ( P < 0.05 ), and the length of hospitalization in minimally invasive group was longer than that in conservative group ( P < 0.05 ). The hematoma volume of minimally invasive group was 16.5 ± 2.4 mL on the 3rd day after operation, and that of conservative group was 27.4 ± 1.8 mL. There was significant difference between the two groups ( P < 0.05 ). In addition, CT showed that the hematoma reduction degree of minimally invasive group was higher than that of conservative group, and the hematoma dissipation rate was higher than that of conservative group on the 3rd and 7th day ( P < 0.05 ). The good MRS score in minimally invasive group was 3.15 times that in conservative group, and the good ADL score was 1.6 times that in conservative group, and there was significant difference in the total score between the two groups ( P < 0.05 ). Minimally invasive puncture drainage is better than conservative treatment in the clearance of hematoma, which is conducive to the recovery of neurological function and daily life of patients with cerebral hemorrhage and is of great help to the prognosis of patients.
