Abstract Objective The aim of this study was to evaluate the accuracy of patient-specific three-dimensional printed drill guides (3D-PDG) for the placement of a coxofemoral toggle via a minimally invasive approach. Materials and Methods Pre-procedure computed tomography (CT) data of 19 canine cadaveric hips were used to design a cadaver-specific 3D-PDG that conformed to the proximal femur. Femoral and acetabular bone tunnels were drilled through the 3D-PDG, and a coxofemoral toggle pin was placed. The accuracy of tunnel placement was evaluated with post-procedure CT and gross dissection. Results Coxofemoral toggle pins were successfully placed in all dogs. Mean exit point translation at the fovea capitis was 2.5 mm (0.2–7.5) when comparing pre- and post-procedure CT scans. Gross dissection revealed the bone tunnel exited the fovea capitis inside (3/19), partially inside (12/19) and outside of (4/19) the ligament of the head of the femur. Placement of the bone tunnel through the acetabulum was inside (16/19), partially inside (1/19) and outside (2/19) of the acetabular fossa. Small 1 to 2 mm articular cartilage fragments were noted in 10 of 19 specimens. Clinical Significance Three-dimensional printed drill guide designed for coxofemoral toggle pin application is feasible. Errors are attributed to surgical execution and identification of the borders of the fovea capitis on CT data. Future studies should investigate modifications to 3D-PDG design and methods. Three-dimensional printed drill guide for coxofemoral toggle pin placement warrants consideration for use in select clinical cases of traumatic coxofemoral luxation.

Abstract BACKGROUND Surgical approaches to the orbit are challenging and require combined multispecialist skills. Considering its increasing relevance in neurosurgical practice, keyhole surgery could be also applied to this field. However, mastering a minimally invasive approach necessitates an extended learning curve. For this reason, virtual reality (VR) can be effectively used for planning and training in this demanding surgical technique. OBJECTIVE To validate the mini fronto-orbital (mFO) approach to the superomedial orbit, using VR planning and specimen dissections, conjugating the principles of skull base and keyhole neurosurgery. METHODS Three-dimensional measurements were performed thanks to Surgical Theater (Surgical Theater© LLC), and then, simulated craniotomies were implemented on cadaver specimens. RESULTS The mFO approach affords optimal exposure and operability in the target area and reduced risks of surrounding normal tissue injuries. The eyebrow skin incision, the minimal soft-tissue retraction, the limited temporalis muscle dissection and the single-piece craniotomy, as planned with VR, are the key elements of this minimally invasive approach. Furthermore, the “window-opening” cotton-tip intraorbital dissection technique, based on widening surgical corridors between neuromuscular bundles, provides a safe orientation and a deep access inside the orbit, thereby significantly limiting the risk of jeopardizing neurovascular structures. CONCLUSION The mFO approach associated to the window-opening dissection technique can be considered safe, effective, suitable, and convenient for treating lesions located in the superomedial orbital aspect, up to the orbital apex.

Anterior Cruciate

The medial collateral ligament (MCL) and the anterior cruciate ligament (ACL) are the most commonly damaged ligaments of the knee. These are common injuries in young people and athletes. Joint laxity may contribute to long-term cartilage degeneration in the medial compartment and give functional limitations as a result of severe lesions of ACL and MCL treated conservatively. In severe acute injuries and chronic symptomatic instabilities should be indicated surgical treatment. The anatomical technique of medial reconstruction of the knee returns stability and allows a distribution of the normal load in patients with severe or chronic acute injuries. Anatomical reconstructions require large incisions and dissections of soft tissues, favoring the risk of contracture in flexion or extension. The technique we used in our series consists of a modification of Laprade’s anatomical technique through a non-anatomical triangular medial reconstruction of the knee, using a minimally invasive approach. Objectives: Show our technique in combined injuries of medial collateral ligament and ACL. Methods: Observational study, case series, retrospective. Population of five patients (N: 5) adults of both sexes, older than 18 years, with a diagnosis of combined lesion of MCL grade II - III with clinical and subjective instability and complete rupture of ACL that have been treated surgically with an anatomical reconstruction using arthroscopic approach of the ACL and a triangular reconstruction with the modified anatomical technique of LaPrade through a minimally invasive approach by the Orthopedics and Traumatology Service of the Reina Fabiola University Clinic. A descriptive statistical analysis of the data was performed. Results: A total of five patients with an average age of 27 ± 10.89 years were included. Of the total 4 (80%) correspond to the male sex. 100% of the cases presented a grade III lesion of the MCL. Patients were followed for an average of 16 ± 9.28 months. The ROM achieved by the patients was of full extension (0°) in 100% of them and flexion in average of 130° ± 14,14. All the cases presented exceeded 100° of flexion. Pain (EVA) 0.45 / 10. The maneuvers of the internal yawn and Lachman were negative in the whole series. According to Lysholm’s functional score, there was an improvement on average of 50.40 ± 6.23 points between the preoperative evaluation, which was initially poor (40.40 ± 9.91) and the post-operative excellent (90.80 ± 4.97). All the cases in the series presented a response to treatment greater than 84 points according to the Lysholm score, with an average good to excellent result in the total. Conclusion: Although there are anatomical techniques validated for the reconstruction of the MCL, the vast majority of them involves an extensive approach with the consequent damage of soft tissues derived from it. The current trend consists of a less aggressive treatment of LCM with an associated reconstruction of the ACL. The fact of performing an anatomical reconstruction with good initial and stable fixation, minimizing soft tissue damage, aims at early rehabilitation, decreasing the chances of rigidity. We did not observe any significant limitation in the ROM, nor post-surgical rigidity in our series of patients. All of them presented a good to excellent Lysholm score and no complications were observed. This type of construct is less invasive and more practical to perform, since it uses a fixation device less than the anatomical technique of LaPrade, which reduces the cost of surgery and decreases less the bone stock, on the other hand the surgical time is not prolonged. Other advantages are that it consists of a short construct with low risk of voltage loss, with a favorable isometry and that is fast, easy to perform and reproducible.

Unroofed Coronary Sinus Syndrome

Abstract Background The recent remarkable development of cardiac imaging technology for unroofed coronary sinus syndrome has led to accurate preoperative diagnosis. We report a case of unroofed coronary sinus syndrome repaired via a minimally invasive approach, under the excellent command of three-dimensional transesophageal echocardiography. Case presentation A 77-year-old woman with hypertension was admitted for aggravation of bilateral leg edema and diagnosed with type III unroofed coronary sinus syndrome with Qp/Qs ratio of 1.6:1. The unroofed portion was detected at the atrial side between P2 and P3 of posterior mitral leaflet by preoperative three-dimensional transesophageal echocardiography. Right minithoracotomy was performed at the fourth intercostal space and cardiopulmonary bypass routinely established. Right atriotomy and left atriotomy incisions were made under antegrade cardioplegic arrest. The unroofed portion was revealed at the same location by preoperative transesophageal echocardiography and was clearly recognized only by endoscopy, not by direct vision. It was repaired by direct running suture under endoscopic visualization. We observed no blood cardioplegia leakage or mitral insufficiency, which was also confirmed by postoperative transesophageal echocardiography. The patient’s postoperative course was uneventful and she was discharged home 14 days after surgery without any residual shunt. Conclusions Successful repair of unroofed coronary sinus syndrome was safely and effectively achieved by a minimally invasive approach supported by preoperative three-dimensional transesophageal echocardiography.

Mitral Apparatus

In patients with functional mitral regurgitation, the placement of a sling encircling both papillary muscles in conjunction with mitral annuloplasty appears to be a rational approach for surgical correction, because it addresses both the mitral valve and the deformities of the subvalvular mitral apparatus. Reports in the literature that describe the utilization of this technique are few, and mainly involve a median sternotomy approach. The purpose of this communication is to describe the technical details of performing this procedure via a minimally invasive approach.
