Minimally Invasive Reduction

Background Several minimally invasive techniques were developed for management of intraarticular calcaneal fractures. This study aimed to compare the functional and radiological outcomes of 2 minimally invasive reduction and fixation techniques using cannulated screws or Kirschner wires (K-wires) for fixation. Methods This study was a retrospective comparative review of patients with displaced intraarticular calcaneal fractures, who were treated with cannulated screws or K-wires techniques. Clinical and radiological data were collected and compared between both groups. Functional outcomes and patient satisfaction using the Maryland Foot Score (MFS) and the visual analogue scale (VAS) of pain, in addition to the complications, were compared between both groups. Results In total, 70 patients were included in the study: 34 in the cannulated screws group, with a mean age of 35.2 ± 4 years, and 36 in the K-wires groups, with a mean age of 33.4 ± 3 years. The operative time was shorter in the K-wires group (40.5 ± 5.6 minutes) compared to the cannulated screw group (49.5 ± 4.5 minutes), P < .001. There were no statistically significant differences between both groups regarding the radiological parameters, including Bohler’s angle, angle of Gissane, calcaneal width, height, or length. The mean MFS, mean VAS, and complications were not different between the 2 groups. Conclusion Treatment of displaced intraarticular calcaneal fractures with minimally invasive reduction and fixation using either cannulated screws or K-wires can achieve similar excellent functional and radiological outcomes, with high patient satisfaction. The use of K-wires has the advantage of reduced operative time than cannulated screws. Levels of Evidence: Level III: Retrospective comparative study

Background: Free-handed, flaplessly placed mini dental implants (MDIs) are a valuable, more affordable and minimally invasive treatment to support overdentures in fully edentulous jaws, especially for medically compromised patients. However, critical 3D radiographic evaluation is lacking. This multicenter prospective case series assessed clinical outcome and carried out 3D- cone-beam computerized tomography (CBCT) analysis of free-handed flaplessly placed one-piece maxillary MDIs by an experienced maxillofacial surgeon. Methods: Thirty-one patients suffering from an ill-fitting maxillary denture relating to compromised bone volume (as confirmed on CBCT), with a dentate mandible, were selected. They received 5–6 MDIs free-hand flaplessly placed and mentally guided with preoperative CBCT. Final connection and attachment activation took place six months later. After two years each implant was individually assessed with CBCT for perforations on eight sites. Implant survival, prosthetic failure, clinical stability and sinus/nasal complaints were registered after three years. Results: 32/185 (17.3%) MDIs failed during the provisional loading with non-activated attachments; 17 replacements in 10 patients were performed. Of the 170 actively loaded 170 MDIs, 82.3% survived and 27/31 prostheses (87%) were fully functional. In total 98/170 MDIs showed no perforation. Based on 1360 CBCT observations, 231 perforations (16.9%) were registered. Of most perforations 37 (25%) were observed at the apical tip and 37 were positioned (21%) into the sinus/nasal cavity, although without clinical complaints. Conclusions: Given the compromised population, the minimally invasive procedure and the low treatment cost involved, a failure rate of 17% is substantial, however clinically acceptable given the critical bone condition. However, even in experienced surgical hands, freehanded and flapless placement yield a high risk for implant perforation, although this did not necessarily lead to complications.

Minimally Invasive Osteosynthesis

The purpose of this research was to study long-term results of osteosynthesis of femoral neck treatment by means of the cannulated screw and to assess the degree of shortening of the femoral neck and its effect on functional outcome. Materials and methods. Minimally invasive osteosynthesis by means of the cannulated screws was carried out in 119 patients with fractures of the femoral neck. The long-term results in 112 (94.1%) patients after osteosynthesis in terms of 1 to 3 years after surgery were analyzed. Results and discussion. Fusion of fracture was noted in 89 (79,4%) cases, non-fusion – in 23 (20,6%) cases. It was es-tablished the dependence of the remote functional outcome from the degree of shortening of the femoral neck. In the presence of shortening of the femoral neck of more than 4 mm of excellent and good results were decreased considera-bly. The dependence of the distant functional results age of the patients was identified. The average age of patients with poor outcome was 77,3 years, with satisfactory – 67,7 years, with a good – 64,1 years, with excellent – 55,9 years. The dependence of the remote functional outcome from the type of fracture according to Pauwels and Garden was determined. Positive results were obtained in fractures type Pauwels I-II, Garden I-II, i.e. at the support fractures and the fractures with little displacement of bone fragments. Conclusions. Minimally invasive osteosynthesis by means of the cannulated screw allows to achieve coalescence fracture in 79,4% of cases, so it may be one of the methods of choice for femoral neck fractures, but can also lead to shortening of the femoral neck.

ABSTRACT Mesial temporal sclerosis creates a focal epileptic syndrome that usually requires surgical resection of mesial temporal structures. Objective: To describe a novel operative technique for treatment of temporal lobe epilepsy and its clinical results. Methods: Prospective case-series at a single institution, performed by a single surgeon, from 2006 to 2012. A total of 120 patients were submitted to minimally-invasive keyhole transtemporal amygdalohippocampectomy. Results: Of the patients, 55% were male, and 85% had a right-sided disease. The first 70 surgeries had a mean surgical time of 2.51 hours, and the last 50 surgeries had a mean surgical time of 1.62 hours. There was 3.3% morbidity, and 5% mild temporal muscle atrophy. There was no visual field impairment. On the Engel Outcome Scale at the two-year follow-up, 71% of the patients were Class I, 21% were Class II, and 6% were Class III. Conclusion: This novel technique is feasible and reproducible, with optimal clinical results.

Background. Existing nonsurgical procedures for the treatment of grade I and II internal hemorrhoids are often painful, technically demanding, and often necessitate multiple applications. This study prospectively assessed the safety and efficacy of the HET Bipolar System, a novel minimally invasive device, in the treatment of symptomatic grade I and II internal hemorrhoids. Methods. Patients with symptomatic grade I or II internal hemorrhoids despite medical management underwent hemorrhoidal ligation with the HET Bipolar System. Endpoints included resolution or improvement of hemorrhoidal bleeding and/or prolapse from baseline, recurrent or refractory symptoms, and pain. Results. Twenty patients were treated with the HET Bipolar System. Two were lost to follow-up. Refractory or recurrent bleeding was present in 8 of 18 (44.4%), 4 of 11 (36.4%), and 4 of 8 (50.0%) patients, and prolapse was reported by 1 of 18 (5.6%), 4 of 11 (36.4%), and 1/7 (14.3%) of patients at 1, 3, and 6 months, respectively. Bleeding improved from baseline in 88.2%, 81.8%, and 87.5% of patients, and resolution of baseline prolapse was seen in 11 of 11 (100%), 4 of 7 (57.1%), and 5 of 5 (100%) patients at the same intervals. Thirteen of 18 (72.2%) patients did not require additional treatment for their symptoms. Conclusions. The HET Bipolar System is safe and easy to use with short-term effectiveness comparable to that of currently used techniques for the treatment of symptomatic grade I and II internal hemorrhoids. It may be an effective alternative to rubber band ligation in patients with larger internal hemorrhoids and those with hemorrhoids close to the dentate line in which banding may produce debilitating pain.

Study Design: This was a prospective case series of 30 patients with post-discectomy syndrome with an average of 18 months of follow-up (level IV).Purpose: The efficacy of post-discectomy syndrome managed by minimally invasive surgery transforaminal lumbar interbody fusion (MIS-TLIF) was evaluated.Overview of Literature: In post-discectomy syndrome wherein conservative treatment had failed, the best surgical treatment modality still remains controversial.Methods: Patients were functionally assessed using the Visual Analog Scale (VAS) for low back pain (LBP) and leg pain (LP) and Oswestry Disability Index (ODI). Radiological fusion was confirmed with plain X-rays and when indicated with computed tomography scan at 12 months postoperatively. A total of 30 patients with 37 operated at lumbar levels with failed discectomy surgery who met our inclusion criteria were treated with MIS-TLIF.Results: The ODI of all patients showed significant improvement from a mean of 73.78% preoperatively to 16.67% at 1 month and 14.13% at 12 months postoperatively. The preoperative LBP VAS score (mean, 4.37) showed a significant decrease (<i>p</i> <0.001) to 1.90 at 1 month and 1.10 at 12 months. Preoperative LP VAS score of limb pain averaged 7.53 and showed a significant (<i>p</i> <0.001) decrease to 3.47 at 1 month and 1.10 at 12 months. All patients attained radiological fusion at 12 months.Conclusions: MIS-TILF constitutes a valid and effective treatment option for patients with post-discectomy syndrome.
