A Staged Protocol for Treatment of High-Energy Tongue-Type Calcaneus Fractures: Surgical Technique and Case Series.

Displaced tongue-type calcaneus fractures are frequently associated with severe soft tissue injuries, and urgent relief of the displaced tongue fragment on the posterior soft tissues is essential to preventing soft tissue complications. If there is a complex articular injury, the soft tissue envelope often needs time for swelling to resolve to allow for a safe open anatomic reduction because premature open reduction internal fixation is often associated with increased complications. We have found that in high-energy tongue-type calcaneus fractures with complex articular injuries, a staged protocol consisting of initial percutaneous reduction and fixation with later definitive reconstruction is soft tissue friendly, allows early restoration of calcaneal morphology, and affords extensile approaches for eventual reconstruction. The purpose of this study was to describe our protocol of staged treatment of high-energy tongue-type calcaneus fractures, along with postoperative surgical outcomes, in a case series of 53 patients.Our series of patients had a high rate of intra-articular injury with marked initial displacement (mean Bohler angle -8.4±20.8 degrees). They were treated initially with percutaneous reduction and fixation at median 1 day postinjury (interquartile range [IQR] 0-1) and definitively at median 16 days postinjury (IQR 10-33). In this series, 2 of 53 (3.8%) patients developed a deep wound infection.In high-energy tongue-type calcaneus fractures at risk for soft tissue compromise or with a significantly displaced tongue fragment without initial soft tissue compromise, we found that staged management represents a feasible management strategy to mitigate risk of soft tissue complications and therefore helps facilitate safe definitive open treatment.

Plating of Proximal Ulna Fractures Using Posterolateral Distal Humerus Plates: Surgical Technique and Case Series.

Precontoured olecranon plates are frequently used in the management of proximal ulna fractures. Occasionally, in comminuted proximal ulna fractures or segmental ulna fractures, available precontoured olecranon plates are too short for the management of these fractures. The authors have utilized posterolateral distal humerus plates in these instances. The coronal bend in some posterolateral distal humerus plates anecdotally fits well to the proximal ulna, despite being designed for the distal humerus. We sought to measure the coronal angulation of precontoured posterolateral distal humerus plates from various companies and compare these to established proximal ulna angles. Case examples are also provided.

The Pterygosphenoidal Triangle: Surgical Anatomy and Case Series in Endoscopic Endonasal Skull Base Surgery.

Safe exposure of the lacerum segment of the carotid artery remains a challenge in endoscopic endonasal surgery. To introduce the pterygosphenoidal triangle as a novel and reliable landmark for facilitating access to the foramen lacerum. Fifteen colored silicone-injected anatomic specimens were dissected using an endoscopic endonasal approach to the foramen lacerum region in a stepwise manner. Twelve dried skulls were studied and 30 high-resolution computed tomography scans were analyzed to measure the borders and angles of the pterygosphenoidal triangle. Surgical cases incorporating the foramen lacerum exposure between July 2018 and December 2021 were reviewed to provide surgical outcomes of the proposed surgical technique. The pterygosphenoidal triangle is delineated by the pterygosphenoidal fissure medially and the vidian nerve laterally. The palatovaginal artery is located at the base of the triangle anteriorly, while the apex is formed by the pterygoid tubercle posteriorly, which leads to the anterior wall of the foramen lacerum and lacerum internal carotid artery. In the reviewed surgical cases, 39 patients underwent 46 foramen lacerum approaches for resection of pituitary adenoma (12 patients), meningioma (6 patients), chondrosarcoma (5 patients), chordoma (5 patients), or other lesions (11 patients). There were no carotid injuries or ischemic events. Near-total resection was achieved in 33 (85%) of 39 patients (gross-total in 20 [51%]). This study details the pterygosphenoidal triangle as a novel and practical anatomic surgical landmark for safe and effective exposure of the foramen lacerum in endoscopic endonasal surgery.

Difficult Tracheostomy in Calcified Tracheal Rings - Surgical Case Series

Background: Surgical airway management in an acute setting of road traffic accident can be difficult, even in the context of an anatomically normal airway. Tracheostomy, as a surgery is dependent on the exposure and removal of upper tracheal rings. When these rings are found calcified, it leads to further difficulties or complications in management, at times even resulting in surgical emphysema. Methods: A series of 6 adults, all males, aged between 32-45 years, presented to us individually between Nov 2021 to Nov 2022, with history of road traffic accidents causing poly trauma and requiring immediate airway stabilization. Results: None of them had prior history of neck trauma or endotracheal intubation or chronic cough. Chest x ray was normal in all of these individuals. Elective tracheostomy under general anesthesia was performed on day 5 of endotracheal intubation. During the procedure of conventional tracheostomy, after retracting the thyroid isthmus upwards, and prior to making a tracheal window, tracheal rings 3 and 4 were found to be calcified, which prolonged the time taken to remove a piece of cartilage. Conclusion: A junior surgeon needs to be well versed with the surgical anatomy of the region, the surgical procedure and management of possible complications with confidence and ease. A lack of knowledge amongst junior medical staff coupled with unskilled assistance when managing such cases lead to increased operative times and hence complications.

Optimizing Workflow in Combined Petrosectomy Approaches: Surgical Technique and Case Series

The combined petrosectomy is one of the workhorse skull base approaches to the petroclival region. Traditionally, this approach starts with a temporosuboccipital craniotomy, followed by the mastoidectomy/anterior petrosectomy, and completed with the dural opening/tumor resection. This sequence of events (neurosurgery-neuro-otology-neurosurgery) involves at least 2 handoffs and change of surgical teams and instrumentation. This report describes a resequencing of events and a modification of the technique used to craft the temporosuboccipital craniotomy, with aims to reducing handoffs between surgical teams and improving operating room workflow. Adhering to PROCESS guidelines, a case series is provided in addition to the surgical technique and surgical images. The technique for performing a combined petrosectomy is described with illustrations. This description shows that the temporal bone drilling may be performed before the craniotomy to allow for direct visualization of the dura and sinuses before completing the craniotomy. In doing so, only 1 transition between the otolaryngologist and neurosurgeon is necessary, thereby improving operating room workflow and time management. A series of 10 patients is presented, showing the feasibility of this procedure and providing operative details that were previously absent in the peer-reviewed literature. Combined petrosectomy, although often performed in a 3-step manner with the neurosurgeon starting the craniotomy, can be performed as described here in a 2-step manner, with similar outcomes and reasonable operating time.

The clinical use of computer aided designed/computer aided manufactured titanium nitride coated implant abutments: Surgical and prosthetic considerations-A case series.

To describe the clinical use of nitride-coated titanium CAD/CAM implant abutments in the maxillary esthetic zone in two patients with high esthetic and functional demands and, to highlight the advantages of nitride-coated milled titanium abutments when compared to stock/custom titanium, one-piece monolithic zirconia, and hybrid metal-zirconia implant abutments. Due to the inherent mechanical and esthetic clinical challenges, single implant-supported reconstructions in the maxillary esthetic zone are a complex restorative treatment. While CAD/CAM technology has been suggested to enhance and ease implant abutment design and manufacturing, implant abutment material selection remains as a critical decision affecting restoration's long-term clinical outcomes. To date, considering the esthetic disadvantages of conventional titanium implant abutments, the mechanical limitations of one-piece zirconia abutments and the manufacturing time and costs associated with hybrid metal-zirconia abutments, no abutment material can be considered "ideal" for all clinical scenarios. Due to their biocompatibility, biomechanical characteristics (hardness and wear resistance), optical properties (yellow color), and peri-implant soft tissue esthetic integration, the use of CAD/CAM titanium nitride-coated implant abutments has been suggested as a predictable implant abutment material in mechanically challenging but esthetically demanding clinical situations, as the maxillary esthetic zone. Two patients requiring a combined tooth-implant restorative treatment in the maxillary esthetic zone were treated using CAD/CAM nitride coated titanium implant abutments. The principal advantages of TiN coated abutments include comparable clinical outcomes to stock abutments, optimal biocompatibility, adequate fracture, wear, and corrosion resistance, reduced bacterial adhesion, and excellent esthetic integration with adjacent soft tissues. Clinical reports and short term mechanical, biological and esthetic clinical outcomes indicate that CAD/CAM nitride coated titanium implant abutments can represent a predictable restorative alternative to stock/custom and metal/zirconia implant abutments and be considered a clinical relevant option in mechanically challenging but esthetically demanding situations, as often found in the maxillary esthetic zone.

Simultaneous Limited Incision Carpal Tunnel Release and Flexor Digitorum Superficialis Opponensplasty Using a Transverse Carpal Ligament Pulley: Surgical Technique and Case Series.

Severe thenar muscle atrophy resulting in dysfunctional thumb abduction and opposition is a well-documented finding associated with long-standing severe carpal tunnel syndrome. This problem has been addressed in the past through various opposition tendon transfers. Historically, the Camitz procedure, or its modifications using the palmaris longus tendon, were recommended. However, this procedure requires a long incision in the palm, extensive dissection including the wrist area, and may not produce active thumb pronation. Our surgical technique describes an open limited palmar-only carpal tunnel release with ring finger flexor digitorum superficialis opponensplasty using a slit through the released transverse carpal ligament as a pulley and dual insertion of the tendon in both the extensor hood and the tendon of the abductor pollicis brevis. The Kapandji evaluation of thumb opposition was used to determine the outcome after surgery.

Fecal Microbiota Transplantation for Fulminant Clostridioides Difficile Infection: A Combined Medical and Surgical Case Series.

Urgent abdominal colectomy is indicated for patients with fulminant Clostridioides difficile infection (CDI) when other medical therapies fail, yet mortality remains high. Fecal microbiota transplant is a less invasive alternative approach for patients with fulminant CDI. We report the 30-day complications of patients with fulminant CDI who underwent either abdominal colectomy, fecal microbiota transplantation (FMT), or FMT followed by abdominal colectomy (FMT-CO). Methods: We performed a single-center, retrospective case review of combined medical and surgical patients with CDI at a large academic medical center between 2008 and 2016. Cohorts were identified as patients with fulminant CDI who underwent total abdominal colectomy alone (CO), FMT alone (FMT), or FMT-CO. We analyzed patient demographics, history, comorbidities, clinical and laboratory variables, CDI severity scores, and mortality outcomes at 30 days. Results: We identified 5,150 patients with CDI at our center during the review period; 16 patients met the criteria for fulminant CDI and were included in this study, with four patients in the CO cohort, eight patients in the FMT cohort, and four patients in the FMT-CO cohort. Demographics and CDI severity scores were similar for all three groups, although the selected comorbidity profiles differed significantly among the three cohorts. The 30-day mortality rates for patients in the CO, FMT, and FMT-CO groups were 25%, 12.5%, and 25%, respectively. Conclusions: FMT is an alternative or adjunctive therapy to colectomy for patients with fulminant CDI that is not associated with increased mortality. Implementation of FMT protocols in clinical practice would be dependent on the availability of qualified transplant material and successful early identification of patients likely to benefit from FMT.

Use of a biological scaffold in the cleavage area in complex revision breast augmentation: A surgical technique and case series

BackgroundBilateral breast augmentation has been the top surgical procedure performed worldwide by plastic surgeons for the past 5 years. Complex breast revision patients are challenging, with the cleavage area being one of the most difficult areas to navigate. We present a novel technique for using biological scaffolds in revision breast augmentation surgery. MethodsA step-by-step surgical technique is presented, combined with a series of 11 cases where either SurgiMend® acellular dermal matrix (ADM) or GalaFLEX mesh was used specifically in the medial cleavage area to correct a difficult to manage soft tissue contour deformity. ResultsEleven patients underwent revision breast augmentation with the use of the biological scaffolds in the medial cleavage area. The mean age was 43 years with a range of 29–68 years. All replacement breast implants were anatomical-shaped, medium profile, polyurethane-coated implants. GalaFLEX® mesh was used in six patients; five patients received SurgiMend® ADM. Mastopexy was performed in 8/11 patients. There were two complications in the same patient in this series, one emergency return to theater for bleeding and one minor scar revision. ConclusionsRevision breast augmentation surgery includes a smorgasbord of options that can be used individually or in combination, such as full or partial capsulectomy, removal alone or replacement of the implant, change to the tissue plane of where the implant sits, mastopexy, and fat transfer. In addition to these recognized treatments, we would like to advocate the option of a biological scaffold for extra support of the cleavage area in complex revision cases.

Advanced Hepatocellular Carcinoma in Adults Without Cirrhosis: A Single-Institution Retrospective Review.

Although up to one in five cases of hepatocellular carcinoma (HCC) occurs in patients without cirrhosis, there is scarce literature characterizing non-cirrhotic HCC (NCHCC). Existing NCHCC research is primarily limited to surgical case series and there is a lack of data on unresectable NCHCC. The purpose of this retrospective review was to compare the characteristics of unresectable NCHCC and cirrhotic hepatocellular carcinoma (CHCC). A retrospective chart review of adult patients with unresectable HCC treated from 2007 to 2017 was performed at the University of Florida Shands Hospital. The data set was stratified into two cohorts: NCHCC and CHCC. Continuous variables were compared using Wilcoxon-Mann-Whitney tests and Kruskal-Wallis rank-sum tests. Categorical variables were compared using Pearson's Chi-squared tests and Fisher's exact tests. Overall survival was explored utilizing the Kaplan-Meier and log-rank method. There were 1494 adult patients included in the final analysis, including 264 patients (17.7%) with NCHCC and 1230 patients (82.3%) with CHCC. Median age was 61.0 years old and median follow-up time was 30.2 months. NCHCC patients were older than CHCC patients (66.3 years vs 61.9 years; p < 0.0001). NHCC tumors were larger than CHCC tumors (7.92 ± 4.85 vs 4.38 ± 3.12 cm; p < 0.0001) and more likely to be associated with distant metastases (23.35% vs 15.91%; p = 0.0055). There was no difference in overall survival, with a median of 23.5 months in NCHCC and 22.4 months in CHCC (p = 0.9196). Our findings suggest that unresectable NCHCC and CHCC have unique characteristics but similar overall survival. To the best of our knowledge, this is the largest comparison of CHCC and NCHCC.

High-grade dysplastic spondylolisthesis: surgical technique and case series

PurposeThe aim of the present study is to evaluate the results of our all posterior-one stage surgical technique for the reduction and fusion of high-grade high-dysplastic spondylolisthesis.MethodsPatients over 11 years old with high-grade spondylolisthesis treated by reduction and circumferential fusion with a posterior-only approach were reviewed. Data about operative time, blood loss, length of stay, intra- and postoperative complications were collected. Meyerding grade (M), lumbar lordosis (LL), thoracic kyphosis (TK), pelvic incidence (PI), pelvic tilt (PT), lumbosacral angle (LSA), slip angle (SLIP), lumbar index (LI) and severity index were measured on preoperative and last follow-up. Sagittal vertical axis (SVA) was used to assess sagittal balance.ResultsOf the 14 included patients, L5-S1 arthrodesis was performed in 12 cases, and L4-S1 was performed in 2 cases. Average surgical time was 275 ± 65 min; average blood loss was 635 ± 375 mL. Average length of stay of was 3.9 ± 1.5 days. The SLIP angle improves from 33.8° ± 7.3° to 6.4° ± 2.5°, (p = 0.002); the lumbosacral angle improves from 68.8° ± 18.6° to 100.7° ± 13.2°, (p = 0.01); and the SVA decreased from 49.4 ± 22.1 mm to 34.4 ± 8.6 mm (p = 0.02). No significant changes were observed in PI, PT and SS. Thoracic kyphosis (TK) and lumbar lordosis (LL) did not change significantly. At last follow-up, no patient had surgical site infection or mechanical complications; no pseudoarthrosis was observed. No revision surgery was performed.ConclusionAlthough technically demanding, reduction and fusion with one stage all posterior approach prove to be a safe and effective.

Tentorial peeling during combined petrosal approach: a cadaveric dissection.

The combined petrosal approach is an excellent method to access the petroclival region but has the inherent risk of injury to the temporal lobe and Vein of Labbé. Tentorial peeling has the potential to largely eliminate these risks during the classic combined transpetrosal approach. Anatomical dissection of three adult injected non-formalin fixed cadaveric heads was performed. Combined petrosal approach with tentorial peeling was completed. A tentorial incision just superior and parallel to the superior petrosal sinus was made to enable peeling of the tentorium into two layers, the posterior fossa tentorial leaf (PFTL), and the temporal tentorial leaf (TTL). Tentorial peeling clearly exposed the continuity betweenthe temporal dura and the TTL as well as the continuity betweenthe presigmoid dura and the PFTL.This enabled the creation of a large dural flap extending to the tentorial incisura, providing wide access to the petroclival region without any exposure of the temporal lobe and/or basal temporal veins.Techniques to create the dural flap without trochlear nerve injury were also explored. The technique of tentorial peeling into two distinct layers has the potential to reduce the morbidity associated with temporal lobe retraction and venous injury. Further cadaveric studies and surgical case series are needed to validate this important surgical nuance in transpetrosal approaches.

Fasciocutaneous flaps in the lower limb soft tissue reconstruction – A surgical case series

Traumatic injuries, metabolic, vascular and malignant diseases are among the main causes of soft tissue defects in the lower limb. The limited tissue resources and the peculiarities of the blood supply make reconstructive treatment a challenge. Various modalities of fasciocutaneous flaps have been gaining popularity in the treatment of soft tissue defects in the lower extremity. A retrospective analysis including a group of 19 patients with soft tissue defects in the lower limb, treated in the period June 2019–July 2021 in the Department of Burns and Plastic Surgery, UMHATEM “N. I. Pirogov” was conducted. Twenty fasciocutaneous flaps were performed (6 - Keystone flaps, 6 - Reverse flow Sural flaps, 4 - Perforator Propeller flaps, 2- V–Y perforator flap, 2 - Axial Rotation flap). Demographic and clinical data is analyzed. Functional (LEFS) and aesthetic evaluation (POSAS 2.0) of the achieved results is obtained. Patients were of both sexes, aged between 23 and 78 years. All of the flaps survived. Minor complications occurred in 3 cases. Significant functional improvement and satisfactory aesthetic results were reported. Free tissue transfer, considered as the “gold standard” in the reconstruction of complex defects involving the lower limb, has its drawbacks. Fasciocutaneous flaps are a good alternative option to free flaps. They are characterized by good functional results and rare complications. Utilization of the fasciocutaneous flap strategy is a reliable method for ensuring the integrity and the function of the lower limb. • Fasciocutaneous flaps can be used reliably in lower limb soft tissue reconstruction. • Respect to the perforasomes is crucial. • Greatest mobility has the sural flap. • Perforator propeller flaps are capable of transferring largest amount of tissue. • Significant functional improvement and satisfactory aesthetic results are reported.

Management of spontaneous cerebrospinal fluid leakage: A surgical case series

BackgroundThe pathophysiology and optimal management of spontaneous cerebrospinal fluid (CSF) leakage is poorly understood. Here, we present a case series of 36 patients who underwent surgical management of spinal CSF leakage with discussion of different surgical approaches to treat different pathological types of spinal CSF leak. MethodsAll patients who underwent surgical management of spinal CSF leakage at two neurosurgical units in Western Australia under the care of a single consultant surgeon from April 2017 were included. Descriptive patient data was retrospectively collected from the medical records, imaging reports and operation notes. Our approach, diagnostic imaging algorithm, surgical methods, and complications are presented. ResultsThirty-six patients were managed surgically from April 2017 – 2021. The median age was 47 years (range; 24–79) with 66 % being female. Regarding pathological culprit, eighteen patients (50 %) had a confirmed CSF leak due to a dural tear, 5 (13 %) a meningeal diverticulum, 2 (5.5 %) a Tarlov cyst and 1 (2.7 %) CSF-venous fistula. Ten patients (27 %) had no spinal CSF leak or dural defect found intraoperatively, despite having positive diagnostic criteria andpositive findings on pre-op imaging scans. In terms of location of pathology, four patients (11 %) underwent cervical level surgery, 27 (75 %) thoracic, 2 (5.5 %) thoracolumbar and 3 (8.3 %) lumbar. Post-operative imaging was available for 26 (72 %) patients, twenty-three (88 %) showed complete resolution of signs of SIH and/or extradural CSF collections, and three (10 %) had MRI spines showing ongoing extradural CSF collections. Thirty patients were contacted for long term follow up, with eighteen (60 %) classified as having good response based on a HIT-6 score less than 50, eight patients (27 %) having partial response and four patients (13 %) having poor response. Four patients (11 %) had non-neurological postoperative complications managed successfully. ConclusionA systematic multidisciplinary approach between interventional neuroradiology and neurosurgery is crucial for assessment of patients with a suspected CSF leak. This approach facilitates timely diagnosis, selection of interventional candidates versus surgical candidates, and improved patient outcomes. In this paper we present our case series which utilises our diagnostic algorithm and individualized surgical approaches based on the pathology and anatomical location of spinal CSF leak.

Gluteus Medius Repair using a Gluteus Maximus Flap Augmented with Synthetic Polyethylene Mesh: Surgical Technique and Case Series.

Gluteus medius tendon tears may not be feasible for direct repair when significant retraction or fatty degeneration is present. Several augmentation techniques have been reported for challenging cases. We describe a novel technique using a transfer of the anterior portion of the gluteus maximus combined with synthetic mesh to reinforce the direct suture of the gluteus medius. The goal of this study was to assess the functional and pain outcomes in three patients treated with this reconstruction technique. A retrospective study was performed including 3 patients with complete and retracted ruptures of the abductor mechanism. When conservative management failed, surgical treatment was attempted. After a minimum follow-up of 12 months (mean follow-up of 18 months), all of the patients showed clinical improvement.The mean Harris Hip Score improved from 31.8 to 75.6, with an average postoperative abduction strength of 3 in the Medical Research Council muscle strength grading system, and no residual limp was noticed. The mean Visual Analogue Scale pain score decreased from 8.3 preoperatively to 1.6 postoperatively. No complications were reported. In conclusion, this technique demonstrates efficacy in terms of improving clinical symptoms and functional status and is a reproducible way to augment irreparable gluteus medius tears.

Percutaneous Reduction of Intra-Articular Posterior Wall Acetabular Rim Fragment: Surgical Technique and Case Series With an Average Follow-Up of 2 Years.

Small posterior wall rim fractures are typically stable; however, if incarcerated in the joint, they must be removed. It is possible to reduce the morbidity associated with open approaches by addressing these incarcerated fragments in a percutaneous manner. This allows the restoration of joint congruity and removal of the osteochondral fragment from the joint space. The following report details the surgical technique to accomplish this, and the results of a case series of patients who underwent this technique. The advantages include limiting the morbidity of an open approach. However, the surgeon must be prepared to convert to an open approach if percutaneous removal does not accomplish the goals of surgery-a concentric, stable hip joint.

Terrible triad injury of the elbow: A PROCESS-compliant surgical case series from Eastern Morocco

IntroductionThe terrible triad of the elbow (TTE) is a lesion associating a dislocation of the elbow, a fracture of the radial head, and a fracture of the coronoid process, with a high potential of complication. The treatment is based on the restoration of bone lesions and external capsular ligament repair. The systematic repair of the medial collateral ligament (MCL) is still debated in the literature. The aim of this study is to evaluate the clinical and functional results of the surgical treatment in a real-world series from Easter Morocco. Patients and methodsThis was a retrospective study of 6 cases of TTE operated by isolated external approach or combined approach (internal or anterior) of the elbow in the department of Traumatology-Orthopedics of the Mohammed VI University Hospital (Oujda Morocco), over a period of 7 years from 2013 to 2020. Radial head and coronoid process fractures were classified according to the Mason and Morrey-Regan classifications, respectively. The following clinical parameters were evaluated: Mayo Clinic Elbow Performance Score (MEPS), Quick Disabilities of the Arm, Shoulder and Hand (DASH), Visual Analog Scale (VAS), and arc of mobility in flexion-extension and prono-supination. Results6 male patients treated between May 2013 and December 2020 were included. The median follow-up was 48 months. All patients had frontal and lateral standard X-ray of over and under joints, and computed tomography (CT)-scan was delivered for 5 cases. The elbow dislocation was posterolateral in five cases, and posteromedial in only one patient. Radial head fractures were classified as type I in one case, type II in two cases, and type III in three cases. Coronoid fractures were type I in three cases, type II in one case, and type III in two cases. At the last follow up, the mean MEPS, Quick DASH, and VAS was 81, 28, 0.8, respectively. The mean arc of mobility in flexion was 120° and it was deficient by 20° in extension. In addition, the mean arc of mobility in protonation was 80°, while in supination it was 75°. Regarding complications, we noticed an instability of the elbow on valgus in a single case, elbow stiffness with heterotopic ossification in a single case, ulnar nerve damage in a single case during medial collateral ligament anchoring, and elbow hygroma in one single case. ConclusionThe surgical management of TTE can provide good and long-term functional results after restoration of the stabilization of bone structures and the lateral ligament complex, without the need to repair the medial collateral ligament.

Endoscopic Endonasal Supraoptic and Infraoptic Approaches for Complex "Parasuprasellar" Lesions: Surgical Anatomy, Technique Nuances, and Case Series.

ObjectiveThe surgical management of lesions involving the lateral area of the suprasellar region, including the lateral aspect of the planum sphenoidale and the tight junction region of the optic canal (OC), anterior clinoid process (ACP), and internal carotid artery (ICA) and its dural rings, is extremely challenging. Here, these regions, namely, the “parasuprasellar” area, are described from the endonasal perspective. Moreover, the authors introduce two novels endoscopic endonasal supraoptic (EESO) and endoscopic endonasal infraoptic (EEIO) approaches to access the parasuprasellar area.MethodsSurgical simulation of the EESO and EEIO approaches to the parasuprasellar area was conducted in 5 silicon-injected specimens. The same techniques were applied in 12 patients with lesions involving the parasuprasellar area.ResultsThe EESO approach provided excellent surgical access to the lateral region of the planum sphenoidale, which corresponds to the orbital gyrus of the frontal lobe. With stepwise bone (OC, optic strut and ACP) removal, dissociation of the ophthalmic artery (OA) and optic nerve (ON), the EEIO approach enables access to the lateral region of the supraclinoidal ICA. These approaches can be used independently or in combination, but are more often employed as a complement to the endoscopic endonasal midline and transcavernous approaches. In clinical application, the EESO and EEIO approaches were successfully performed in 12 patients harboring tumors as well as multiple aneurysms involving the parasuprasellar area. Gross total and subtotal tumor resection were achieved in 9 patients and 1 patient, respectively. For two patients with multiple aneurysms, the lesions were clipped selectively according to location and size. Visual acuity improved in 7 patients, remained stable in 4, and deteriorated in only 1. No postoperative intracranial infection or ICA injury occurred in this series.ConclusionsThe EESO and EEIO approaches offer original treatment options for well-selected lesions involving the parasuprasellar area. They can be combined with the endoscopic endonasal midline and transcavernous approaches to remove extensive pathologies involving the intrasellar, suprasellar, sphenoid, and cavernous sinuses and even the bifurcation of the ICA. This work for the first time pushes the boundary of the endoscopic endonasal approach lateral to the supraclinoidal ICA and ON.

The direct posterior gluteal muscle splitting approach for posterior access to acetabular fractures: Surgical technique and case series

We present a minimally invasive direct posterior, gluteal muscle splitting approach (PMS) as an alternative to the traditional Kocher-Langenbeck (KL) approach for posterior access to acetabular fractures. We believe it offers significant advantages and provides improved access while maximizing the range of fracture patterns that can be addressed through a posterior approach.One hundred and eighty-four consecutive patients treated with this approach by the senior author (RMS) between 2001 and 2018 were reviewed. The most common individual fracture pattern addressed was a posterior wall (66/36%) but more complex combination fracture types were the dominant group (106/58%), and included transverse with posterior wall, posterior wall / posterior column, and T types. A radiographically congruent reduction was consistently obtained at surgery, without any operative sciatic nerve palsies and a comparable heterotopic bone formation rate to previous reports. We have reviewed all 120 patients who were followed beyond 6 months and noted the hip replacement conversion rates to be different with each fracture type. The rate was highest with Transverse/ posterior wall injuries (36%), 16% of the posterior wall injuries were converted, a history of dislocation was not specifically associated with conversion.We believe this approach improves the posterior access to the acetabulum, but this study also confirms the poor prognosis of specific groups of higher energy multi-fragmentary, posterior acetabular injuries and suggests the need for a classification system that better predicts the prognosis for the hip joint.
