Spinal extradural foraminal neoplasms are uncommon lesions that are traditionally resected via an open laminectomy and facetectomy approach. In this paper the authors present their mini-open approach for the removal of 3 such tumors. The authors retrospectively reviewed 3 patients with extradural schwannoma who underwent mini-open resection and fusion between June 2006 and July 2007. Clinical data, tumor characteristics, and outcomes were analyzed. All 3 patients underwent successful mini-open treatment of their spinal neoplasms. Postoperative MR imaging demonstrated complete resection in 2 cases and subtotal resection in 1 case. Extradural foraminal neoplasms can be safely and effectively treated with mini-open techniques. Reductions in blood loss, hospitalization, and tissue disruption may be potential benefits of this approach.

ABSTRACT Purpose Osteochondroplasty of the femoral head-neck junction can improve hip pain and function in patients with femoroacetabular impingement. We report our initial series of patients undergoing surgical treatment for symptomatic CAM type femoroacetabular impingement using a combined arthroscopic and mini-open approach. Materials and methods A retrospective chart review of 20 consecutive patients was performed. Seventeen patients had adequate follow-up for inclusion. Preoperative clinical and radiographic characteristics as well as intraoperative findings were obtained from patient records. Postoperative Harris Hip scores and VAS pain scores were recorded at final follow-up. Results At an average of 27.8 months (range 12-48 months), the mean Harris Hip score improved from 64.7 preoperatively to 86.8 (p < 0.001). The mean VAS pain score improved from 4.80 to 1.53 (p = 0.001). Two patients (11.7%) underwent total hip arthroplasty at an average of 15 months postoperatively. Fourteen patients (82%) stated they would have the procedure again. There were no significant complications. Conclusion Surgical treatment of CAM type femoroacetabular impingement using a combined arthroscopic and mini-open anterior hip approach has a low complication rate and improves functional and pain scores at short-term follow-up.

OBJECTIVESpinal tumors account for 2%–4% of all tumors of the central nervous system and can be intramedullary, intradural extramedullary, or extradural. In the past, wide approaches were used to obtain safe access to these tumors, as complete resection is the goal in treating most tumor entities. To reduce surgical complications due to large skin incisions and destabilizing laminectomies, minimally invasive approaches were established. In this study, the authors share their experience with mini-open approaches to intradural tumor pathologies.METHODSThe authors retrospectively reviewed cases involving patients with intramedullary and intradural extramedullary lesions treated between 2009 and 2016. They present their surgical mini-open approach to the spinal cord as well as unique characteristics, key steps, and postsurgical complications for specific tumor subgroups (meningioma, neuroma, and intramedullary tumors).RESULTSA total of 245 intradural tumors were surgically treated during the study period. Of these lesions, 151 were intradural extramedullary meningiomas (n = 79) or neuromas (n = 72). Nine (12.5%) of the neuromas were dumbbell neuromas. Ninety-four tumors were intramedullary. The mean age of the patients was 51.4 years, and 53.9% were female. The mean duration of follow-up was 46.0 months.All meningiomas and neuromas could be resected using a mini-open keyhole approach, but only 5.3% of the intramedullary lesions could be accessed using this technique. Of the 94 patients with intramedullary tumors, 76.6% required a laminotomy, 7.4% required a hemilaminectomy, and 10.6% required a 2-level laminectomy. Only 2 of the patients with intramedullary tumors needed stabilization for progressive cervical kyphosis during follow-up. None of the other patients developed spinal instability after undergoing surgery via the mini-open (keyhole/interlaminar) approach. There were significantly more surgery-associated complications in the large exposure group than in the patients treated with the mini-open approach (19.1% vs 9.6%, p < 0.01).CONCLUSIONSIntradural extramedullary and in selected cases intramedullary pathologies may safely be resected using a mini-open interlaminar approach. Avoiding laminectomy, laminotomy, and even hemilaminectomy preserves spinal stability and significantly reduces comorbidities, while still allowing for complete resection of these tumors.

Category: Sports Introduction/Purpose: Surgical repair of the Achilles tendon is a commonly-performed procedure in cases of acute tendon rupture. Open Achilles tendon surgery with traditional extensile approach is most often performed with the patient in prone position, but this can interfere with airway access, put increased pressure on the abdomen, and subject to increase perioperative period and comorbidities. Mini-open approach in supine repair may potentially avoid the risks of the prone position, but the safety and utility of this approach have not been established. The purpose of this study is to compare perioperative outcomes between patients undergoing acute Achilles rupture repair with mini-open approach in the supine position versus traditional approach in the prone position. Methods: Patients who underwent surgical repair of acute Achilles rupture between the years 2011 and 2018 at a single institution were retrospectively identified using CPT code 27650. Patients who underwent concurrent procedures for additional injuries were excluded. Charts of included patients were retrospectively reviewed for demographic information, intraoperative characteristics, and postoperative outcomes. Statistical analysis was conducted and p-values =0.05 were considered significant. Results: A total of 81 patients were included for analysis, 26 supine and 55 prone. Baseline characteristics were statistically similar between the two groups. Average total time in the operating room was significantly greater among patients in the prone position (118.7 minutes) than those in the supine position (100 minutes) (p = 0.0011). Average surgery time, blood loss, and time in PACU were greater among the prone group than the supine group, although these differences were not statistically significant. Average postoperative pain score, infection rate, dehiscence rate, sepsis rate, and DVT rate were also similar between the two groups. Conclusion: The mini open approach in supine position may be advantageous in repair of acute Achilles rupture in that it significantly reduces total time in the operating room while maintaining positive patient outcomes. Prospective clinical studies are warranted to validate these assessments.

Category: Ankle, Ankle Arthritis, Arthroscopy, Basic Sciences/Biologics Introduction/Purpose: Ankle arthrodesis is a gold standard for end-stage ankle arthritis after conservative managements fail. It may be done through direct anterior, lateral, arthroscopic or mini open approaches. Joint preparation, apposition of joint surfaces and stable fixation are very important for successful outcomes. Ankle arthrodesis maybe associated with infection, chronic pain and nonunion - of these, nonunion is the most common complication reported. Achieving union is of utmost importance while minimizing complications associated with the procedure. Regardless of approach or fixation method, preparation of articular surface is of paramount importance for successful union and may be limited by the approach used. Our study aims to evaluate the difference between direct lateral and dual mini-open approaches (extended arthroscopic portals) in terms of joint preparation. Methods: We used 10 below knee fresh-frozen cadaver legs for this cadaveric study. Ankle joints of five specimens were prepared through the lateral approach, while the remaining five ankles were prepared using dual mini incisions. After the completion of preparation, all ankles were dissected to open, photographic images of tibial plafond and talar articular were taken. Surface areas of each articular facet and unprepared cartilage of the talus, distal tibia, and distal fibula were measured and analyzed using ImageJ software. Results: Significantly greater amount of total surface area was prepared among specimens using mini-open approach compared to those with trans-fibular approach. The percentage of total articulating surface area prepared (including talus and tibia/fibula), talus, tibia and fibula in trans-fibular approach were 76.9%, 77.7% and 75% respectively. The percentages were 90.9%, 92.9%, and 88.6% in mini-open approach. While the medial gutter was well prepared with mini incision technique (unprepared surface 44 .64% vs 91.08%), lateral gutter was well prepared in trans-fibular technique (88.82vs 82.04 square cm). There is no difference in the amount of unprepared surface of talar dome between the two approaches. When excluding the medial gutter, there was no significant difference between trans-fibular and mini open techniques (83.94 vs 90.85, p=0.1412). Conclusion: Joint preparation using the mini-open approach (extended arthroscopic portal) is equally as efficacious as the transfibular approach for preparation of the tibiotalar joint. When including preparation of the medial gutter, the mini-open approach provides superior joint preparation. This may be advantageous with decreased rate of nonunion and less complications. But many surgeons fuse only tibiotalar surface, considering that, both approaches yield equal amount of joint preparation. But it needs to be confirmed with clinical studies.
