Purpose. To describe the minimally invasive technique for cement augmentation of cannulated and fenestrated screws using an injection cannula as well as to report its safety and efficacy.Methods. A total of 157 cannulated and fenestrated pedicle screws had been cement-augmented during minimally invasive posterior screw-rod spondylodesis in 35 patients from January to December 2012. Retrospective evaluation of cement extravasation and screw loosening was carried out in postoperative plain radiographs and thin-sliced triplanar computed tomography scans.Results. Twenty-seven, largely prevertebral cement extravasations were detected in 157 screws (17.2%). None of the cement extravasations was causing a clinical sequela like a new neurological deficit. One screw loosening was noted (0.6%) after a mean follow-up of 12.8 months. We observed no cementation-associated complication like pulmonary embolism or hemodynamic insufficiency.Conclusions. The presented minimally invasive cement augmentation technique using an injection cannula facilitates convenient and safe cement delivery through polyaxial cannulated and fenestrated screws during minimally invasive screw-rod spondylodesis. Nevertheless, the optimal injection technique and design of fenestrated screws have yet to be identified. This trial is registered with German Clinical TrialsDRKS00006726.

We describe a novel minimally invasive technique for the treatment of trigger thumb. 37 patients with a total of 41 thumbs were included in the study. A visual analogue pain scale was used before surgery and also at 2 week and 6 month follow up visits. The pain was significantly improved from a pre op of 7.92 (+/- 1.6) to .65 (+/- .8) at the 2 week follow up and finally .29 (+/- 1.8) at the 6 month follow up. All of the patients had relief of triggering and only 1 patient required any therapy. This endoscopic technique for trigger thumb allows the surgeon to perform a trigger release with a minimal incision and provides excellent relief without any complications.

Introduction: Metatarsophalangeal joint arthrodesis (MTPA) is a surgical technique indicated for the treatment of hallux rigidus with advanced arthrosis and for rheumatic diseases. This classic surgery is widely used and effective; however, the use of a minimally invasive technique remains mostly unknown. Objective: To present the outcome of MTPA performed using a percutaneous technique. Methods: Hallux MTPA was performed in 8 feet from 4 patients with hallux rigidus and 4 with rheumatoid arthritis, with a higher prevalence of women than men (5 vs. 3) and a mean postoperative follow-up time of 1.5 years. The outcomes were evaluated using a modified version of the American Orthopedic Foot and Ankle Society (AOFAS) questionnaire and the union time. Results: All patients who underwent surgery showed improvements in pain and arthrodesis union at approximately 8 weeks. The mean AOFAS score increased to 85 points (of a total of 90 possible points). There were no complications, such as infection, nonunion or persistent pain. Conclusion: The percutaneous technique of hallux MTPA was effective, with satisfactory outcomes, reduced surgical invasiveness, immediate walking, rapid union with “arthrodesis take” and significant improvement in pain. However, a larger sample is required to confirm the outcomes.

The aim of this study was to assess the results of 5-year experience with minimally invasive operation without medial incision and resection cartilages for correction of pectum excavatum. From 2000 we made in our Hospital minimally invasive technique for the correction of pectus excavatum. 75 patients were treated by minimally invasive technique. A convex steel bar is inserted under the sternumtrough small bilateral Incisions. The steel bar is inserted with the convexity facing posteriorly, and when it is in position, the bar is turned over. After 2 years the bar is removed when permanent remolding has occurred. Initial excelent results were maintained in 54 patients (normal chest), good results in 16 (mild residual pectus) and poor in 5 (severe recurrence requiring further treatment). The mean follow-up since surgery were 3 months to 3 years. Average blood loss was 25 ml. Average length of hospital stay was 8 days. Patients returned to full activity after 2 month. Complications were pneumothorax in 12 patients, pneumonia in 6 patients and displacement of the steel barr requiring revision in 2 patients. Poor results occurred because steel bar was too soft in 3 patients, and soft sternum in 2 patients with Marfan’s syndrome. The minimally invesive technique is effective without cartilage incision and resection or sternal osteotomy.

Purpose: To evaluate the midterm clinical outcome of patients treated with a balloon-expandable polytetrafluoroethylene (ePTFE) endograft for long-segment occlusive disease of the femoropopliteal segment. Methods: Eighty-nine patients (68 men; median age 69 years, range 43–81) with disabling claudication (n=73) or critical ischemia (n=16) were treated with an ePTFE endograft (mean length 29 cm) for 7 stenosis (mean length 9 cm) and 82 occlusions (mean length 19 cm) in the femoropopliteal segment. The follow-up protocol included Doppler ankle-brachial pressure measurement and duplex scanning or angiography of the endograft at 6-month intervals. Primary and secondary patency rates were analyzed. Results: At the last examination, the endograft was patent in 52 patients (median 17 months, range 7–50) and occluded in 35 (median 7 months, range 0–40);2 patients died of nonvascular causes with a patent endograft at 6.5 and 7 months. At follow-up, the primary and secondary endograft patency rates were 71% and 83% at 6 months, 57% and 69% at 1 year, 45% and 49% at 2 years, and 30% and 44% at 3 years, respectively. Conclusions: The midterm success of this new ePTFE endograft is limited; therefore, the device needs to be refined if this minimally invasive technique is to compete with conventional bypass surgery.

<strong>Introduction</strong>: Warts are benign tumours that commonly involve skin and other epithelial tissues. There is no single treatment modality that is 100% effective. In multiple warts, especially on face, palms, and soles destructive procedure are inappropriate and impractical. Homologous autoimplantation is a simple technique, which helps in inducing cell mediated response, causing clearance of warts. <strong>Aims and objectives</strong>: To evaluate the effect of homologous autoimplantation therapy in treatment of multiple warts. To study the untoward effects of this treatment. Material and methods: A total of 49 patients of viral warts were included in study. Homologous autoimplantation of wart was done and regular follow up was done to see the result. <strong>Results</strong>: Out of 49 patients, in 24 patients there was good response, 14 showed moderate response, 5 showed poor response and in 6 patients there was no response. <strong>Conclusion</strong>: Homologous autoimplantation is an easy, minimally invasive technique which clears multiple, recurrent and recalcitrant warts.

Purpose: To report a case of a cyclodialysis cleft that was successfully managed with gas endotamponade and cyclocryotherapy. Methods: A 37-year-old male victim of a severe blunt ocular trauma was referred to our service for evaluation and treatment of a left eye hypotony. Clinical examination revealed an intraocular pressure of 2 mm Hg, a cyclodialysis cleft extending from the 11 to 1 o'clock positions and a hypotonic maculopathy. Left eye best corrected visual acuity (BCVA) was 3/10. The patient failed to respond to conservative treatment with atropine 1%, so a single bubble of 16% C2F6 was injected into the vitreous cavity, followed by superior quadrant transconjunctival cyclocryotherapy. Results: After gas absorption, the intraocular pressure increased to 11 mm Hg and became steady during the 24 months of follow-up. His hypotonic maculopathy resolved, and the BCVA improved to 9/10. Complete closure of the cyclodialysis cleft was documented with ultrasound biomicroscopy. Conclusion: Cryotherapy associated with gas endotamponade is a minimally invasive technique that could be considered for patients with cyclodialysis clefts that fail to respond to medical therapy.

Background: Calcaneus is a spongy cancellous bone with rich blood supply , its fracture heals more rapidly providing no occurrence of infection and soft tissue injury around ,no gross malposition of fragments. The associated pain leads to a major impairment in life quality. The aim of treatment for calcaneal fractures is the decrease of pain and rebuilding of walking ability for patients with normal foot shape and the ability to wear normal foot wear. To reduce complications, a minimally invasive technique for the treatment of displaced intra-articular fractures of the calcaneus was preferred to use. The purpose of this study was to determine whether the closed reduction and percutaneous K. wire fixation of displaced intra-articular calcaneal fractures results in better functional outcome at a minimum one year follow up after the injury compared with those after non-operative management. Methods: One hundred and eleven displaced closed intra-articular calcaneal fracture in 105 patients (six were bilateral) were seen at the orthopedic department of Al-Kindy teaching hospital and Shaih Zaid hospital , only 45 cases included in this study and prospectively evaluated with an average follow-up time of minimum  of one year (1–3years follow-up). For radiographic evaluation, plain radiographs and CT scans were obtained. The Maryland Foot Score was used for clinical estimate. Sanders type II, III and IV fractures were diagnosed. Results: The incidence of subtalar arthritis was correlated with the severity of fracture. Böhler’s angle was restored in 70.1% (47 of 67) of the cases. The majority (77.7%) of patients were content with their treatment result. The rate of significant complications was 6.5%. Discussion: Percutaneous K. wire fixation of displaced intra-articular calcaneal fractures presented minimally invasive technique which showed comparable results with a low rate of serious complications and is a viable alternative for the treatment of intra-articular, dislocated calcaneal fractures. Conclusions: the functional results after K. wires fixation of displaced intra-articular calcaneal fractures were better than those after non-operative care.

AimTo report the complications observed in a consecutive large series of cases treated with keratopigmentation (KTP).MethodsKTP was performed in 234 eyes of 204 patients for therapeutic and cosmetic reasons. From them, 50 eyes of 29 patients suffered complications. Different KTP techniques and three generations of pigments (GP) were used. The follow-up period ranged from 4 months to 12 years. Light sensitivity (LS), visual field (VF) limitations and MRI alterations were considered functional complications. Organic complications were described as change in colour, colour fading and neovascularisation.ResultsThe percentage of complications was 12.82%. Most patients complained of LS (49%), then colour fading and change in colour (19%). Neovascularisation, VF limitations and MRI complications constituted 7%, 4% and 2%, respectively. Organic complications were observed with the previous GP but resolved with the latest third GP with CE mark certification (Conformité Européene). Although LS remained with the corneal-specific pigments, it gradually disappeared in most of the patients (81.81%) 6 months postoperatively.ConclusionTo the best of our knowledge this is the first time a study systematically and comprehensively approaches and reports KTP complications. KTP with third GP provides better results and fewer complications than previous ones. It is a modern, minimally invasive technique that helps solve several functional ocular problems and improves cosmetic appearance of the patients. Dermatological pigments should not be used as they lead to complications; instead pigments specifically tested for the eye in terms of toxicity and teratogenicity should be used.
