Combined Anterolateral and Posterior Approach in Total Hip Arthroplasty for Chronic Post-traumatic Hip Dislocation: A Case Report.

Hip dislocation is rare, and it typically results from high-energy trauma such as traffic accidents. Its management involves prompt reduction of the dislocated hip to minimize the risk of subsequent femoral head necrosis. Consequently, cases of chronic hip dislocation are extremely rare. This report presents a case of a 33-year-old male with chronic posterior hip dislocation due to a traffic accident 13 years ago. The left femoral head was completely dislocated posteriorly from the acetabulum, forming a false acetabulum with an arthritic change. The patient experienced difficulty walking and performing daily activities due to pain. We performed a total hip arthroplasty (THA) using a combined anterolateral and posterior approach. The outcome was favorable, with no complications during the two-year follow-up period. THA using a combined anterolateral and posterior approach is a valuable option for patients with chronic post-traumatic hip dislocation because it offers the advantages of optical visibility and the management of the adhered soft tissues.

The effect of combined head and tail approach during laparoscopic D3 lymph node dissection on pain severity and complications in patients with right colon cancer.

OBJECTIVE: To examine the impact of a combined craniocaudal approach on pain and complications during laparoscopic D3 lymph node dissection in clients diagnosed with right colon cancer (RCC). METHODS: 100 RCC patients were divided into Group A and Group B. Both groups underwent laparoscopic D3 lymph node dissection, with Group A undergoing an intermediate approach and Group B undergoing a combined head and tail approach. Two groups of patients' perioperative (surgical time, intraoperative blood loss, number of lymph node dissection) indicators, postoperative recovery (postoperative exhaust time, postoperative hospital stay, drainage tube removal time) indicators, perioperative pain level (VAS scores 1, 3, and 5 days following surgery), and incidence of complications (vascular injury, intestinal obstruction, anastomotic bleeding, incision infection), and the therapeutic efficacy [CEA, CA19-9] indicators were compared. RESULTS: Clients in the B team had substantially shorter operating times and considerably fewer intraoperative hemorrhage than those in the A team. The VAS grades of clients in the B team were considerably lower than those in the A team the day following surgery. Clients in the B team experienced vascular injury at a substantially lower rate than those in the A team. The overall incidence rate of problems did not differ statistically significantly between the A team and the B team. Following therapy, teams A and B's CEA and CA19-9 levels were considerably lower than those of the same team prior to therapy. CONCLUSION: Combined craniocaudal technique can significantly reduce intraoperative bleeding, postoperative pain, and the risk of sequelae from vascular injuries.

Would the one-stage combined approach lead to better long-term neurological outcomes than the posterior approach alone in multilevel degenerative cervical myelopathy patients with T2-Weighted increased signal intensity? An 8-year follow-up results and propensity score matching analysis.

BACKGROUND: T2-weighted increased signal intensity (ISI) is commonly recognized as a sign of more severe spinal cord lesions, usually accompanied by worse neurological deficits and possibly worse postoperative neurological recovery. The combined approach could achieve better decompression and better neurological recovery for multilevel degenerative cervical myelopathy (MDCM). The choice of surgical approach for MDCM with intramedullary T2-weighted ISI remains disputed. This study aimed to compare the neurological outcomes of posterior and one-stage combined posteroanterior approaches for MDCM with T2-weighted ISI. METHODS: A total of 83 consecutive MDCM patients with confirmed ISI with at least three intervertebral segments operated between 2012 and 2014 were retrospectively enrolled. Preoperative demographic, radiological and clinical condition variables were collected, and neurological conditions were evaluated by the Japanese Orthopedic Assessment score (JOA) and Neck Disability Index (NDI). Propensity score matching analysis was conducted to produce pairs of patients with comparable preoperative conditions from the posterior-alone and combined groups. Both short-term and mid-term surgical outcomes were evaluated, including the JOA recovery rate (JOARR), NDI improvements, complications, and reoperations. RESULTS: A total of 83 patients were enrolled, of which 38 and 45 patients underwent posterior surgery alone and one-stage posteroanterior surgery, respectively. After propensity score matching, 38 pairs of comparable patients from the posterior and combined groups were matched. The matched groups presented similar preoperative clinical and radiological features and the mean follow-up duration were 111.6 ± 8.9 months. The preoperative JOA scores of the posterior and combined groups were 11.5 ± 2.2 and 11.1 ± 2.3, respectively (p = 0.613). The combined group presented with prolonged surgery duration(108.8 ± 28.0 and 186.1 ± 47.3 min, p = 0.028) and greater blood loss(276.3 ± 139.1 and 382.1 ± 283.1 ml, p<0.001). At short-term follow-up, the combined group presented a higher JOARR than the posterior group (posterior group: 50.7%±46.6%, combined group: 70.4%±20.3%, p = 0.024), while no significant difference in JOARR was observed between the groups at long-term follow-up (posterior group: 49.2%±48.5%, combined group: 59.6%±47.6%, p = 0.136). No significant difference was found in the overall complication and reoperation rates. CONCLUSIONS: For MDCM patients with ISI, both posterior and one-stage posteroanterior approaches could achieve considerable neurological alleviations in short-term and long-term follow-up. With greater surgical trauma, the combined group presented better short-term JOARR but did not show higher efficacy in long-term neurological function preservation in patients with comparable preoperative conditions.

Surgical complications in combined rhinoplasty and endoscopic sinus surgery.

KEY POINTS: Complications in combined surgery are equivalent to ESS but are higher than rhinoplasty alone. The most common complications are pneumonia, stroke, and epistaxis. Rhinoplasty surgeries with graft use have a higher risk of complications.

Surgical treatment of coronal shear fractures of the distal humerus with an intact lateral epicondyle by the lateral combined approach.

BACKGROUND: Coronal shear fractures of the distal humerus are not only rare and prone to misdiagnosis, but their surgical treatment can be challenging. We aimed to investigate the feasibility of exposing distal humeral coronal shear fractures with a combined lateral approach that preserves the extensors and lateral ulnar collateral ligament (LUCL) and to analyze the clinical efficacy of open reduction and internal fixation (ORIF) in the treatment of these injuries. METHODS: We included 45 patients who sustained coronal shear fractures of the distal humerus with the lateral epicondyle intact and were treated with ORIF from January 2013 to August 2020. The fractures were exposed by the lateral combined approach in which the tendons involving the common extensor, the extensor carpi ulnaris (ECU), and the LUCL were preserved. Two observation windows were formed anterior to and posterior to these tendons and the LUCL was used to achieve fracture reduction. Countersunk screws, with or without a plate placed on the posterior lateral condyle, were used to fix the fragments. The functional outcomes of these patients were reviewed and assessed with physical and radiographic examinations, range of motion (ROM) measurements, and self-evaluation Mayo Elbow Performance Index (MEPI) and Disabilities of the Arm, Shoulder, and Hand (DASH) scores. RESULTS: In total, 40 patients were followed up with for over 1 year and were included in the final analysis. The mean follow-up duration was 42±30 months (range, 12-107 months). The patients' mean age was 42 years (range, 14-74 years). According to the Dubberley Classification, there were 15 type I, 17 type II, and 8 type III fractures. At the final follow-up, the mean flexion-extension arc was 131° (range, 65-150) and mean pronation and supination was 73° (range, 45-80) and 71° (range, 40-80), respectively. The mean MEPI score was 88 (range, 61-97) points; the results were excellent in 21, good in 13, fair in 4, and poor in 2 patients. The mean DASH score was 11 (range, 0-42) points. Neither functional score nor range of movement was associated with age, sex, fracture type, injury type, or surgical timing. CONCLUSION: Reduction and stable fixation with internal fixation for coronal shear fractures of the distal humerus can be achieved by the lateral combined approach. Early functional mobilization allows for satisfactory restoration of elbow function.

Rejuvenation in Men Facial Aging: A Combined Approach.

Facelift surgery, also known as rhytidectomy, is a popular cosmetic procedure aimed at reversing the signs of facial aging. While facelift surgery is more commonly performed in women, an increasing number of men are seeking this procedure to maintain a youthful appearance. The long recovery period conflicts the overall primary outcome anticipated by men undergoing rhytidectomy, i.e., appear younger, youthful, and ready to reaffirm their value in the working environment. Anterior direct neck lift, blepharoplasty (upper and lower eyelid blepharoplasty), and lipofilling are three techniques that have been shown to be effective in improving facial rejuvenation outcomes in elderly male patients. However, there is little to no evidence of the safety and efficacy of these techniques when used in combination. By combining these techniques, we hypothesized that we could achieve outcomes comparable to traditional facelift surgery, but with a lower risk of complications and a shorter recovery time. We conducted a retrospective case series study of 18 male patients who underwent facial rejuvenation surgery using the combination of anterior direct neck lift, blepharoplasty (upper and lower eyelid blepharoplasty), and lipofilling at our institution between 2018 and 2021. All 18 patients completed the study, with an average follow-up of 12 months. No major complications were observed, and all patients reported a high level of satisfaction with their outcomes.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Combined approach in the treatment of comminuted lateral Hoffa fracture: a case report.

Coronal-plane intra-articular fractures of the femoral condyle (Hoffa fractures) are rare, and difficult to diagnose and treat. They mostly result as a consequence of high-energy trauma and are combined with concomitant fractures (patellar, tibia shaft) and/or soft-tissue damage. A plain X-ray can miss the diagnosis initially and therefore computerized tomography scan is recommended, which can also help in the preoperative planning. The vast majority of these fractures are unicondylar (mostly lateral condyle fractured). The approach for their treatment can be anterior or posterior. In cases of fracture comminution, much more mutilant approaches with osteotomy have been described. A combined two-stage approach can be used to obtain anatomical reduction and fixation of all the fragments. We present a case of a 46-year-old male patient with comminuted lateral Hoffa fracture treated with a combined approach (extended posterior approach to the proximal tibia and lateral parapatellar) in a time interval of one month.

Surgical management of giant pituitary adenomas: institutional experience and clinical outcomes of 94 patients.

Background: Giant (with a diameter of at least 40 mm and a volume of at least 10 cm3) pituitary adenomas (GPAs) are intricate tumors that pose considerable difficulty for surgical removal. While endoscopic transsphenoidal surgery (ETS) is a commonly employed technique for these destructive tumors, its effectiveness may be restricted in cases where invasion into multiple compartments is present, leading to limited resection. Methods: A retrospective review was conducted on the clinical records of 94 patients diagnosed with GPAs who had undergone surgical resection from 2014 to 2022. An analysis was conducted on the outcomes of the surgical and clinical procedures. Results: In this group, the average size of the tumor before surgery was 44.6 ± 5.6 mm (range, 40-73 mm), and the volume was 25. 5± 16.6 cm3 (range, 10-20.67 cm3). Of the total number of patients, 72 (76.6%) underwent a single ETS, 12 (12.8%) opted for transcranial surgery (TCS), and 10 (10.6%) chose a combined method. Gross total resection (GTR) was successfully performed in 49 (68.1%), 3 (25.0%), and 8 (80.0%) patients who underwent each surgical approach. Seventy-four (78.7%) patients had improved vision, 20 (21.3%) were unchanged, and none had deterioration. Twenty-two patients (23.4%) experienced a total of 43 complications, which comprised hormonal insufficiency (11/94, 11.7%), diabetic insipidus (6/88, 6.8%), electrolyte disorders (7/94, 7.4%), cerebrospinal fluid leakage (5/94, 5.3%), meningitis (8/94, 8.5%), and hydrocephalus (6/94, 6.4%). The GTR, subtotal resection (STR), and partial resection (PTR) rates were 63.8% (60/94), 21.3% (20/94), and 14.9% (14/94), respectively. Throughout the follow-up duration, 18.1% (17/94) of patients required reoperation and/or adjuvant radiation treatment as a result of tumor regrowth or inadequate biochemical remission of functioning GPAs. Conclusion: ETS remains the optimal surgical option for most GPAs and generally offers safe and efficient tumor resection. However, a combined approach with TCS remains a requirement in cases that are not suitable for treatment with a single ETS. To achieve optimal tumor removal and minimize the occurrence of surgical complications, a flexible combination of ETS and TCS is recommended based on the characteristics of the tumor.

[Comparison of posterolateral approach and combined approach in treatment of Mason type 2B posterior malleolar fracture].

Objective: To compare the effectiveness between the posterolateral approach and the posterolateral combined posteromedial approaches in the treatment of Mason type 2B posterior malleolar fracture. Methods: A retrospective analysis was performed on the clinical data of 79 patients with posterior ankle fracture who met the selection criteria between January 2015 and January 2022. There were 62 cases of Mason 2B Pilon subtype and 17 cases of avulsion subtype. Among Mason 2B Pilon subtype patients, 35 were treated with posterolateral approach (group A), 27 patients were treated with combined approach (group B). There was no significant difference in gender, age, injured side, cause of injury, time from injury to operation, preoperative hospital stay, preoperative visualanalogue scale (VAS) score, and intraoperative internal fixation between the two groups ( P>0.05). All patients with Mason 2B avulsion subtype were treated by posterolateral approach, including 7 males and 10 females, aged from 25 to 68 years, with an average of 46.1 years. The operation time, intraoperative blood loss, postoperative hospital stay, and complications were recorded. The reduction quality was evaluated by Ovadia deals radiographic score, and the ankle function and pain were evaluated by VAS score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and ankle range of motion. Results: Mason 2B Pilon subtype: There was no significant difference in operation time, intraoperative blood loss, postoperative hospital stay, and follow-up time between the two groups ( P>0.05). The radiological evaluation of Ovadia deals in group A was significantly worse than that in group B ( P<0.05). The VAS score in the two groups significantly improved at each time point after operation, and the VAS score and AOFAS score further improved with the extension of time after operation, and the differences were significant ( P<0.05). Except that the AOFAS score of group A was significantly lower than that of group B at last follow-up ( P<0.05), there was no significant difference in VAS score and AOFAS score between the two groups at other time points ( P>0.05). At last follow-up, the ankle range of motion in group A was significantly less than that in group B ( P<0.05). There was no significant difference in the incidence of sural nerve injury, deep tissue infection, limitation of toe movement, and traumatic ankle arthritis between the two groups ( P>0.05). Mason 2B avulsion subtype: The operation time was (119.47±20.61) minutes and the intraoperative blood loss was 50 (35, 55) mL. Seventeen patients were followed up 13-25 months, with an average of 18 months. The Ovadia deals score was excellent in 10 cases, good in 6 cases, and poor in 1 case at 1 week after operation, and the excellent and good rate was 94.1%. All fractures healed in 8-18 weeks with an average of 12.35 weeks. There were 1 case of sural nerve injury and 3 cases of traumatic ankle arthritis after operation. No deep tissue infection or limitation of toe movement occurred. The VAS score decreased significantly and AOFAS score increased significantly with time, and the differences were significant between different time points before and after operation ( P<0.05). The ankle range of motion at last follow-up was (56.71±2.47)°. Conclusion: Compared with the posterolateral approach, the combined approach is a better choice for the treatment of Mason 2B Pilon subtype. If the posteromedial bone block does not affect the reduction of the medial malleolus, the posterolateral approach can achieve good effectiveness for Mason 2B avulsion subtype.

Combined telovelar posterolateral (far lateral) approach for the resection of a large posterior fossa ependymoma: how I do it.

BACKGROUND: Ependymomas are glial cell tumors whose recommended treatment, according to the recent European guidelines, is surgical. Patient outcomes, in terms of progression-free survival and overall survival, are strongly related to the extent of resection. However, in some cases, critical locations and/or large dimensions could make a gross total resection challenging. In this article, we describe the surgical anatomy and technique of a combined telovelar-posterolateral approach for the resection of a giant posterior fossa ependymoma. METHODS: A 24-year-old patient who presented to our institution complaining of a 3-month history of headache, vertigo, and imbalance. Preoperative MRI scans showed a large mass within the fourth ventricle, extending towards the left cerebellopontine angle and perimedullary space through the homolateral Luschka foramen. Surgical treatment was proposed with the aims of releasing the preoperative symptoms, obtaining the tumor's histopathological and molecular definition, and preventing any future neurological deterioration. The patient gave his written consent for surgery and consented to the publication of his images. A combined telovelar-posterolateral approach was then performed to maximize the tumor's exposure and resection. Surgical technique and anatomical exposure have been extensively described, and a 2-dimensional operative video has been included. RESULTS: The postoperative MRI scan demonstrated an almost complete resection of the lesion, with only a millimetric tumor remnant infiltrating the uppermost portion of the inferior medullary velum. Histo-molecular analysis revealed a grade 2 ependymoma. The patient was discharged home neurologically intact. CONCLUSIONS: The combined telovelar-posterolateral approach allowed to achieve a near total resection of a giant multicompartimental mass within the posterior fossa in a single surgical stage.

Endoscopy Assisted Removal of Post Traumatic Impacted Foreign Body in the Nose Extending into Opposite Parapharyngeal Space.

The head and neck region is a complex anatomical area with vulnerable nervous and vascular structures, auditory and visual organs and upper aero-digestive tract. Penetrating foreign bodies of head and neck region are not uncommon and pertain mostly to wood, metal and glass (Levine et al. in Am J Emerg Med 26:918-922, 2008). This case report describes an airborne high velocity foreign body blown off from a lawn mower penetrating the left side of the face, penetrating deep into nasopharynx and opposite parapharyngeal space through paranasal sinuses. A multidisciplinary team managed this case successfully, avoiding injuries to adjacent vital skull base structures.

Combined supracerebellar infratentorial and right occipital interhemispheric approach to falcotentorial junction meningioma: A case report.

Background: Falcotentorial meningioma is a rare tumor of pineal region, arising from the dural folds where the tentorium and falx meet. Due to the deep location and near closeness to significant neurovascular structures, gross-total tumor resection in this area can be complicated. Pineal meningiomas can be resected using a variety of approaches; however, all these approaches are associated with a significant risk of postoperative complications. Case Description: A 50-year-old female patient who presented with several headaches and visual field defect and diagnosed with pineal region tumor is discussed in the case report. Patient was successfully managed surgically by combined supracerebellar infratentorial and right occipital interhemispheric approach. Cerebrospinal fluid circulation was restored after surgery and neurological defects were regressed. Conclusion: Our case shows that it is possible to completely remove giant falcotentorial meningiomas with minimal brain retraction, preserve the straight sinus and vein of Galen, and prevent neurological impairments by combining two approaches.

Double plating via anterolateral and posterolateral approach for distal femoral fracture.

Although there are some reports highlighting the applicability of double plates in distal femoral fractures, there is no standard approach or fixation method for supracondylar fractures combined with posterior coronal shear fractures. We report a case of distal femoral fracture treated with a lateral locking plate and posterior buttress plate using anterolateral and posterolateral approaches from one incision. A 70-year-old man was hit by a motorcycle and had an intra-articular distal femoral fracture involving a long medial proximal spike and a single lateral condyle fragment, with the lateral condyle fragment posteriorly displaced. A 12-cm lateral skin incision was made, and the joint was developed using a para-patellar approach from the anterior to iliotibial band. Posterior buttress plate fixation was successfully performed from behind the iliotibial band using a posterolateral approach, followed by cannulated cancellous screw and lateral locking plate fixation from the anterolateral window. Combined anterolateral and posterolateral approaches from one incision enable intra-articular exposure and fixation based on fixation principles for lateral condyle fragments combined with supracondylar fracture.

Surgical Approach to Cervical Fractures in Ankylosing Spondylitis Patients: Rationale and Surgical Strategy.

BACKGROUND: Current literature lacks objective criteria to determine surgical management in patients with ankylosing spondylitis who sustain cervical fractures. The purpose of our study was to analyze the determinants for stratifying surgical approach, evaluate the outcome in patients, and postulate a management strategy. METHODS: This was a retrospective study of patients with ankylosing spondylitis who underwent surgery for cervical spine injury with a minimum follow-up of 2 years. Neurological recovery, fracture pattern including translation and angulation, surgical duration, blood loss, and postoperative complications were recorded, and a comparative analysis of these factors with anterior, posterior, and combined surgical approaches was performed. RESULTS: The study included 43 men with a mean age of 57 years; 49% underwent anterior-only stabilization, 16% underwent posterior-only stabilization, and 35% underwent combined anteroposterior stabilization. Mean operative time was significantly lower in anterior-only (81.4 minutes; P < 0.05) and posterior-only (124 minutes; P < 0.05) approaches compared with combined approach (266.6 minutes). Mean blood loss was significantly lower in anterior-only (87.5 mL, P < 0.05) approach compared with posterior-only (714.7 mL) and combined (912.7 mL) approaches. Mean translation was 1.8 mm, 1.7 mm, and 3.7 mm in anterior, posterior, and combined approaches (P < 0.05), respectively. CONCLUSIONS: Our study provides insights into management of cervical spine fractures in ankylosing spondylitis patients. A fracture displacement ≤2 mm may be successfully managed by an anterior approach, while the posterior approach may be beneficial in similar fractures warranting instrumentation extending to the thoracic spine. All other fractures warrant a combined surgical approach.

Sialendoscopy-assisted combined approach for parotid sialolithotomy: Our long-term experience.

OBJECTIVES: To assess the long-term outcome of sialendoscopy-assisted combined approach for parotid sialolithotomy with gland preservation. PATIENTS AND METHODS: A retrospective study of patients treated with a combined sialendoscopic and open approach was conducted between 2011 and 2020. Demographic data of patients such as operative technique, stone size, stone location, complications, and symptom relief were collected. Patients were followed up via clinical examination and questionnaires. RESULTS: Seventy-four patients were included and underwent endoscopy-assisted combined operations for the removal of 98 parotid stones. Of the 98 stones, 92(94%) stones were completely removed and 6(6%) were partially removed. At a mean follow-up of 47.1 ± 35 months, 65 of 74 patients (88%) achieved long-term success. Patients with stone incomplete removal were significantly more often to develop the recurrence of obstructive symptoms (p = 0.000) There were no cases of facial nerve injury or fistula formation. Gland function was preserved in 73 of 74 patients (99%). CONCLUSIONS: The combined approach for parotid stones is a safe and gland-preserving alternative to parotidectomy. The techniques described here show high success rates and good long-term results, and they avoided the need for gland resection in >95% of cases.

Recent progress in endoscopic skull base surgery: Functional preservation and multiportal approaches.

Over the past couple of decades, endoscopic skull base surgery (ESBS) has significantly evolved and is applied to a broad range of skull base pathologies, including sinonasal malignancies. Recent studies have demonstrated remarkable progress of ESBS in complete resection with low morbidity and extension of its application to larger and more complex lesions. In this review, we focus on the evolution of functional preservation and multiportal approaches. Progress in preoperative assessments and surgical techniques improved the preservation of olfactory function after ESBS. The technical feasibility of olfaction preservation even after resection of olfactory groove lesions has been reported. To overcome the limitations of extending use of the endoscopic endonasal approach in surgical fields, various types of multiportal approaches, including combinations of the endoscopic endonasal and transorbital, transmaxillary, or transoral approach, have been reported, as they are useful for complete resection of extensive pathologies while limiting morbidity. These innovative techniques are still in the process of maturation. Hence, an ongoing critical evaluation is essential to ensure efficacy.
