We present a retrospective review of the early results and complications in a series of 35 consecutive patients with 43 total hip arthroplasties performed through an anterior muscle sparing minimally invasive approach. We found the early complication rates and radiographic outcomes comparable to those reported from arthroplasties performed via traditional approaches. Complications included dislocation (2%), femur fracture (2%), greater trochanteric fracture (12%), postoperative periprosthetic intertrochanteric fracture (2%), femoral nerve palsy (5%), hematoma (2%), and postoperative iliopsoas avulsion (2%). Radiographic analysis revealed average cup anteversion of19.6°±6.6, average cup abduction angle of48.4°±7, stem varus of0.9°±2, and a mean leg length discrepancy of 0.7 mm. The anterior approach to the hip is an attractive alternative to the more traditional approaches. Acceptable component placement with comparable complication rates is possible using a muscle sparing technique which may lead to faster overall recovery.

<b><i>Purpose:</i></b> This study aimed to explore the complication rates of radical cystectomy in patients with muscle-invasive bladder cancer and identify potential risk factors. <b><i>Methods:</i></b> A total of 553 patients were included: 131 were operated on via an open approach (ORC), 242 patients via a laparoscopic method (LRC), and 180 by a robot-assisted procedure (RARC). Patient age, gender, American Society of Anesthesiologists (ASA) score, urinary diversion type, preoperative albumin level, body mass index (BMI), pathological (TNM) stage, and surgical times were collected. The severity of complications was classified according to the Clavien-Dindo scale (Grades 1–5). <b><i>Results:</i></b> The surgical technique was significantly related to the number of complications (<i>p</i> &#x3c; 0.00005). Grade 1 complications were observed most frequently following LRC (52.5%) and RARC (51.1%), whereas mostly Grade 2 complications were detected after ORC (78.6%). Those with less severe complications had significantly higher albumin levels than those with more severe complications (<i>p</i> &#x3c; 0.05). Patients with an elevated BMI had fewer complications if a minimally invasive approach was used rather than ORC. The patient’s general condition (ASA score) did not impact the number of complications, and urinary diversion type did not affect the severity of the complications. Mean surgical time differed according to the urinary diversion type in patients with a similar TNM stage (<i>p</i> &#x3c; 0.005); however, no difference was found in those with more locally advanced disease. Longer operation time and lower protein concentration were associated with higher probability of complication rate, that is, Clavien-Dindo score 3–5. <b><i>Conclusions:</i></b> The risk of complications after RC is not related to the type of urinary diversion, and can be reduced by using a minimally invasive surgical technique, especially in patients with high BMI.

Minimally Invasive Methods

Background: Calcaneal fractures which constitutes 2% of total fractures are frequent and very debilitating if not treated properly. Calcaneal fractures generally affect younger population leading to significant man-days loss(around 2-5 years3) and in-turn leading significant economic burden on the society. The goal of treatment for calcaneal fractures is elimination of pain and restoration of normal foot shape, biomechanics, and walking ability. Wound related complications are common with open surgeries. After open reduction internal fixation with perimeter plates for displaced calcaneal fractures, wound edge necrosis is commonly observed with the extended lateral approach. Because of such high incidence of wound complications in open reduction of calcaneum fractures, minimally invasive approach takes priority over open reduction of these fractures.Methods: The study aimed to evaluate the results of minimally invasive approach for calcaneal fractures. To reduce the operative complications, 30 patients were treated with minimally invasive methods in both extra articular and intra-articular calcaneal fractures and the results were evaluated. All patients were evaluated clinically , functionally and radiologically 3D- CT reconstruction images.Results: All cases were followed up for 2 years at specified intervals. The outcome measures were evaluated by AOFAS scores10 with excellent result in 13 cases and good to fair results in the rest. Operated patients had no wound infection, no skin necrosis, 5 patients had mild subtalar arthrosis and 3 patients complained slight difficulty in wearing shoes. None of them have any gait abnormalities.Conclusions: Our study suggests that the minimally invasive methods will reduce the operative complication rates. The minimally invasive surgical intervention in an expert hand can yield better results with less complication rates.

Abstract A 67-yr-old patient presented with severe paraparesis and lower limb spasticity. The spinal cord magnetic resonance imaging (MRI) revealed the “scalpel sign” 1,2 at the T7 level, suggesting a diagnosis of a dorsal arachnoid web. This video demonstrates a microsurgical technique for the excision of a dorsal arachnoid web with a minimally invasive approach. A paramedian skin incision, understanding the muscular aponeurosis, was performed from T7 to T8. Then, we inserted the tubular dilators until the lamina, to perform a muscle-sparing approach. An expandable tubular retractor of adequate length was passed over the widest dilator and docked into place along the subperiosteal plane. The T7 lamina was drilled, and the resection of the superior and inferior adjacent spine levels was completed with a rongeur. Additional contralateral bone resection was performed after tubular retractor tilt to the midline.3 After dura mater opening, it was carefully suspended and the dorsal arachnoid leaflet was cut to drain the dorsolateral and lateral spinal cisterns.4 The dorsal arachnoid web was, first, disconnected from its lateral anchorages. It was then gently removed with microsurgical forceps, to help its microdissection from the spinal cord surface. At this step, peculiar attention was paid to limit the traction or displacements of the spinal cord and surrounding vessels. Once the dorsal arachnoid web was removed, the quality of the spinal cord decompression was confirmed by its re-expansion. In conclusion, the minimally invasive approach is a safe and appropriate technique for dorsal arachnoid web excision.2,5,6-7  The patient gave her informed and signed consent for the writing and publication of this article.  Image at 1:00 reused with permission from Castelnovo G et al, Spontaneous transdural spinal cord herniation, Neurology, 2014;82(14):1290.

Abstract BACKGROUND: Traditional anterior and posterior approaches to the thoracolumbar spine are associated with significant morbidity. In an effort to eliminate these drawbacks, minimally invasive retropleural approaches have been developed. OBJECTIVE: To demonstrate the feasibility and clinical experience of a minimally invasive lateral retropleural approach to the thoracolumbar spine. METHODS: Seven cadaveric dissections were performed in 7 fresh specimens to determine the feasibility of the technique. In each specimen, the lateral aspect of the vertebral body was accessed retropleurally, and a corpectomy was performed. Intraprocedural fluoroscopy and postoperative computed tomography were used to assess the extent of decompression. As an adjunct, 3 clinical cases of thoracic fractures and 1 neurofibroma were treated with this minimally invasive approach. Operative results, complications, and early outcomes were assessed. RESULTS: In the cadaveric study, adequate exposure was obtained to perform a lateral corpectomy and to allow interbody grafting between the adjacent vertebral bodies. The procedures were successfully performed in the 4 clinical cases without conversion to conventional approaches. A pleural tear was noted in the first clinical case, and a chest tube was placed without any long-term sequelae. CONCLUSION: Our early experience suggests that the minimally invasive lateral retropleural approach allows adequate vertebrectomy and canal decompression without the tissue disruption associated with posterolateral approaches. This approach may improve the complication rates that accompany open or endoscopic approaches for thoracolumbar corpectomies.

Abstract OBJECTIVE To demonstrate the feasibility of and initial clinical experience with a novel minimally invasive posterolateral thoracic corpectomy technique. METHODS Seven procedures were performed on 6 cadavers to determine the feasibility of thoracic corpectomy using a minimally invasive approach. The posterolateral thoracic corpectomies were performed with expandable 22 mm diameter tubular retractor paramedian incisions. The posterolateral aspects of the vertebral bodies were accessed extrapleurally, and complete corpectomies were performed. Intraprocedural fluoroscopy and postoperative computed tomography were used to assess the degree of decompression. In addition, 2 clinical cases of T6 burst fracture, 1 T4–T5 plasmacytoma, and 1 T12 colon cancer metastasis were treated using this minimally invasive approach. RESULTS In the cadaveric study, an average of 93% of the ventral canal and 80% of the corresponding vertebral body were removed. The pleura and intrathoracic contents were not violated. Adequate exposure was obtained to allow interbody grafting between the adjacent vertebral bodies. The procedures were successfully performed in the 4 clinical cases using a minimally invasive technique, and the patients demonstrated good outcomes. CONCLUSION Based on this study, minimally invasive posterolateral thoracic corpectomy safely and successfully allows complete spinal canal decompression without the tissue disruption associated with open thoracotomy. This approach may improve the complication rates that accompany open or even thoracoscopic approaches for thoracic corpectomy and may even allow surgical intervention in patients with significant comorbidities.

Introduction: We aimed to evaluate surgical outcomes of hysterectomy for endometriosis performed by general obstetricians and gynecologists (OB/GYNs) based on surgical approach. Methods: Using the 2016–2018 National Surgical Quality Improvement Program (NSQIP) database, we examined surgical outcomes including 30-day complication rates based on surgical approach in patients who underwent a hysterectomy for endometriosis by OB/GYNs. Results: From 2016 to 2018, 3641 hysterectomies were performed by OB/GYNs for endometriosis. 86.0% were performed via a minimally invasive (MIS) approach, with 2882 (79.2%) via a laparoscopic and 247 (6.8%) via a vaginal approach. Compared to MIS hysterectomies, those who underwent an abdominal hysterectomy included a higher proportion of African American and a lower proportion of non-Hispanic white patients, had heavier uteri, lower parity, and were more likely obese (all p < 0.05). There were no differences in age, American Society of Anesthesiologists class, comorbidities other than obesity, or a history of prior abdominal or pelvic surgery (all p > 0.05). Women undergoing hysterectomy for endometriosis experienced an overall 9.8% complication rate. Compared to abdominal approaches, MIS had a lower rate of overall complications (8.5% vs 17.8%) including wound (2.7% vs 7.2%) and major (4.4% vs 8.8%) complications (all p < 0.001). MIS had shorter operative time (129.2 ± 60.9 vs 143.8 ± 71.9), shorter length of stay (0.9 ± 1.6 vs 2.4 ± 1.8), and fewer readmissions (2.8% vs 5.5%) (all p < 0.001). Conclusion: While hysterectomy for endometriosis is a challenging procedure to perform, OB/GYNs are performing this procedure predominantly via a minimally invasive approach with fewer complications and more favorable surgical outcomes than an abdominal approach.

Introduction: The prevalence of radial nerve injury during surgery is as high as the prevalence of radial nerve injury due to trauma. The aim of this study is to minimize the risk of iatrogenic injury of radial nerve. Materials and Methods: Fifty patients with middle or distal diaphysis fractures of humerus and 18 patients with pseudoarthrosis at the same localizations were treated with surgery. Plate-screw fixation was performed with anterior approach in 43 patients. Eleven patients had minimally invasive plate osteosynthesis, and 14 patients had intramedullary nailing. The localization of the radial nerve was determined with nerve stimulator at the area of dissection. Results: Iatrogenic radial nerve injury did not occur in patients treated with open reduction or minimally invasive approach. Discussion: Nerve stimulator may be a method that decreases radial nerve injury, an iatrogenic complication. This method may be used in anterior approach and minimally invasive procedures.

Background: Open reduction and internal fixation is the standard surgical treatment of calcaneal fractures. However, it is associated with a high rate of wound problems. Objectives: In this study, we evaluated the clinical and radiologic outcomes, as well as the wound complication rates of sinus tarsi minimally-invasive approach in the treatment of intra-articular calcaneus fracture. Methods: In a retrospective study, 62 patients who were referred with an intra-articular calcaneus fracture and treated with a minimally-invasive sinus tarsi approach were included. The radiographic evaluations included the assessment of Bohler and Gissane angles before and after the surgery, as well as the height and length of the calcaneus. The clinical outcome was assessed with the American Orthopedic Foot and Ankle Society (AOFAS) questionnaire. Results: The Mean±SD age of the patients was 41.8±12.7 years. The Mean±SD follow-up of the patients was 21.3±10 ‎months. After 6 months, in 43 patients (69.3%) both Bohler’s and Gissane’s angles were significantly improved after the surgery (P=0.003 and P<0.001, respectively). The calcaneus height was significantly improved after the surgery (P=0.009), as well. The Mean±SD AOFAS score of the patients was found 79.6±7. Wound infection was seen in only 1 case (1.6%). Delayed wound healing occurred in 4 cases (6.4%). No other wound complication such as dehiscence and skin necrosis was recorded. Conclusion: Minimally-invasive sinus tarsi approach is an efficacious procedure for the treatment of intra-articular calcaneus fracture with a minimized rate of wound complications.
