AbstractObjective:This case report presents our experience of endoscopic transnasal management of medial intra- and extraconal lesions.Case report:An endoscopic transnasal approach to intra-orbital lesions was used for nine patients. Four patients had intraconal lesions and five had lesions in the extraconal space. Post-operatively, seven patients reported an improvement in visual acuity and two reported stable vision. There were no complications of cerebrospinal leakage or diplopia.Conclusion:This case series demonstrated the safety and effectiveness of an endoscopic transnasal approach to managing intraconal and extraconal lesions. This minimally invasive technique should be considered a valid alternative for accessing orbital tumours, particularly those located in the medial compartment.

AbstractIntroduction:Verrucous carcinoma is a variant of well differentiated squamous cell carcinoma characterised by an exophytic, warty growth which is slowly but locally invasive and which can cause extensive local destruction if left untreated.Case report:We report the first known case of veruccous carcinoma of the paranasal sinuses with rapid orbital invasion. A 58-year-old man presented with right-sided nasal obstruction, a huge right intranasal lesion, intractable dacryocystitis and cutaneous involvement of the nasolacrimal sac region. The tumour was partially removed using an endoscopic transnasal approach. Post-operatively, and while waiting for the histological result, the patient developed signs of rapid invasion of the orbit, with uniocular visual acuity deficit. He underwent combined radiochemotherapy, with a moderate response.Conclusion:Knowledge of the potentially aggressive nature of verrucous carcinoma may be helpful in early management of intraorbital invasion and salvaging of the eye.

Objective: To assess the degree of postoperative satisfaction of patients with acute Achilles tendon rupture who underwent surgical reconstruction by a minimally invasive technique using Tenolig®. Methods: A retrospective observational study was conducted with 18 patients with acute Achilles tendon rupture diagnosed by a positive Thompson test who underwent surgery. Outcomes were assessed using the American  arthopaedic Foot and Ankle Society (AOFAS) score and the Foot Function Index (FFI). Furthermore, quantitative variables were descriptively treated, and patients’ age was correlated with FII and AOFAS score using Spearman’s correlation coefficient at a significance level of 5%. Results: Patients underwent surgery from one to six days after injury and were discharged one day later. Only one patient had a superficial postoperative infection. Patients’ AOFAS scores ranged from 75 to 100 points, and FFI ranged from 0 to 20%. The patient withsuperficial postoperative infection had an AOFAS score and a FFI of 75 points and 20%, respectively. Conclusion: Percutaneous repair of complete Achilles tendon rupture with Tenolig® resulted in high functional scores and a low rate of complications.

Background: Multiple modalities have been used in the treatment of syringomyelia, including direct drainage, shunting into peritoneal, pleural and subarachnoid spaces. The authors report their experience of surgical treatment of syringomyelia in a minimally invasive fashion. Methods: We conducted a single-center retrospective chart review on our syringomyelia cases treated with minimally invasively using Metrx Quadrant retractor system since January 2011. Lateral fluoroscopy was used to guide the placement of the retractor onto the lamina of the corresponding level. This was followed by laminectomy and a small durotomy. Once the syrinx cavity was identified and the proximal end of the tubing was inserted into the syrinx cavity, the tubing was tunneled into the pleural incision subcutaneously. Insertion of the pleural end of the shunt was performed under the microscope, with removal of a small amount of the rib at its upper edge. Results: 10 procedures were performed in 7 patients by the senior author. Etiologies of syringomyelia included Chiari malformation, trauma, diastematomyelia and kyphoscoliosis. All patients improved neurologically. No patients had immediate postoperative complications. One patient underwent two revisions of syringopleural shunts due to multilobulated nature of syringomyelia. Conclusions: Our case series presents a novel, minimally invasive technique for shunting of syringomyelia with results comparable to open procedures.

Ultrasound Guided

Foreign bodies (FBs) retained in the subcutaneous tissues are a common reason for medical consultation. In small animals, FBs usually consist of vegetal materials, especially grass awns. Failure to remove the FBs is likely to give rise to acute or late complications. The surgical removal of the FBs can be invasive, costly and technically challenging. Ultrasound has become a mainstay in the detection of FBs and it can be used to guide the extraction of the FBs with a minimally invasive technique. This study describes the detection and extraction of soft-tissue FBs in small animals. One hundred-sixty-two patients, presenting at two veterinary clinics with suspected FBs retained in the soft tissues of various body districts, were considered. Once an ultrasound diagnosis was established, the ultrasound-guided removal of the FB was performed. A high-frequency linear transducer, a skin disinfection, sedation or anaesthesia was used when needed and a scalpel and some Hartmann forceps were also used. One hundred-eighty-two FBs were successfully removed in all the patients. In six cases, the FB was identified during a second ultrasonographic examination, after recurrence of the fistula. No complications were reported after the procedure. The extraction of the FB was performed in an echographic suite in 138 cases and in a surgery room with surgical intervention in 24 cases. In the latter situation, the surgical minimally invasive dissection of tissues under ultrasound guidance was performed before the removal of the FB. In conclusion, the ultrasound-guided removal of the FBs retained in the superficial soft tissue can be considered a good alternative to surgery. However, failure to remove a FB does not preclude the removal by traditional surgery.

Object The authors assessed the accuracy of placement of lumbar transpedicular screws by using a computer-assisted, imaged-guided, minimally invasive technique with continuous electromyography (EMG) monitoring. Methods This was a consecutive case series with prospective assessment of procedural accuracy. Forty-seven consecutive patients underwent minimally invasive lumbar interbody fusion and placement of pedicle screws (PSs). A computer-assisted image guidance system involving CT-based images was used to guide screw placement, while EMG continuously monitored the lumbar nerve roots at the operated levels with a 5-mA stimulus applied through the pedicle access needle. All patients underwent CT scanning to determine accuracy of PS placement. All episodes of adjusted screw trajectory based on positive EMG responses were recorded. Pedicle screw misplacement was defined as breach of the pedicle cortex by the screw of more than 2 mm. Results Two hundred twelve PSs were inserted in 47 patients. The screw misplacement rate was 4.7%. One patient experienced new postoperative radiculopathy resulting from a sacral screw that was too long, with lumbosacral trunk impingement. The trajectory of the pedicle access needle was altered intraoperatively on 20 occasions (9.4% of the PSs) based on positive EMG responses, suggesting that nerve root impingement may have resulted from these screws had the EMG monitoring not been used. Conclusions The combination of computer-assisted navigation combined with continuous EMG monitoring during pedicle cannulation results in a low rate of PS misplacement, with avoidance of screw positions that might cause neural injury. Furthermore, this technique allows reduction of the radiation exposure for the surgical team without compromising the accuracy of screw placement.

ABSTRACT Introduction: the number of hip fractures is estimated to increase from 1.66 million in 1990 to 6.26 million by 2050. Internal fixation is the most common surgical treatment for intertrochanteric fractures. Objectives: the objective of the present research is to describe a minimally invasive technique with a modified instrument for the treatment of stable proximal femoral trochanteric fractures using the standard DHS, classified as Tronzo types 1 and 2 (AO 31A1.2), and presenting a case series. Methods: a case was selected to present the technique. Patients operated by this technique undergo a clinical evaluation and preoperative preparation as routine. The criteria for inclusion in the study were the presence of stable fracture of the proximal femur verified by two hip specialist orthopedists, and operated by the minimally invasive technique with a modified instrument using a standard DHS. Exclusion criteria were cases of patients operated for unstable fractures, and the use of other surgical techniques. A case series of 98 patients was performed and discussed. Results: minimally invasive technique with a modified instrument using the standard DHS device can reduce bleeding, it decreases soft tissue injuries, surgical time, and hospital stay, as any other MIPO procedures. Ninety-eight patients underwent the operation (Tronzo types I and II), 59 female and 39 male, ages from 50 to 85 years old. Immediate post-operative complications were shortening of the lower limb, loss of fracture reduction, and death by clinical complications. Conclusion: the present study describes a minimally invasive surgical technique using a modified instrument to perform proximal femoral osteosynthesis for stable trochanteric fractures, using the standard DHS.
