    Abstract: The purpose of this study was to evaluate the relationship between obstructive sleep apnea syndrome (OSAS) and glaucoma progression, and to examine the correlation between OSAS severity and rate of visual field (VF) loss. Methods: Patients with concurrent diagnoses of open-angle glaucoma and OSAS between 2010 and 2016 were identified. Enrollment criteria consisted of glaucomatous optic neuropathy and VF loss, ≥5 reliable VFs, ≥2 years of follow-up, and polysomnography (PSG) within 12 months of final VF. PSG parameters including apnea-hypopnea index (AHI) and oxygen saturation (SpO 2 ) were collected. Eyes were classified as “progressors” or “nonprogressors” based upon event analysis using Glaucoma Progression Analysis criteria. Two-tailed t test comparisons were performed, and correlations between rates of VF loss and PSG parameters were assessed. Results: A total of 141 patients with OSAS and glaucoma were identified. Twenty-five patients (age 67.9±7.6 y) with OSAS (8 mild, 8 moderate, 9 severe) were enrolled. Eleven eyes (44%) were classified as progressors, and had more severe baseline VF loss ( P =0.03). Progressors and nonprogressors had nonsignificantly different ( P 〉 0.05) age (69.9±8.7 vs. 66.4±6.6 y), follow-up (4.4±0.7 vs. 4.3±1.0 y), intraocular pressure (13.1±2.8 vs. 14.9±2.5 mm Hg), mean ocular perfusion pressure (49.7±5.5 vs. 48.8±9.0 mm Hg), AHI (31.3±18.6 vs. 26.4±24.0), body-mass index (27.8±5.5 vs. 28.8±5.6), and SpO 2 (94.1±1.6% vs. 94.0±1.6%). AHI was not correlated with slopes of VF mean deviation ( r , −0.271; P , 0.190) or pattern standard deviation ( r , 0.211; P , 0.312), and no substantial increase in risk of progression was found with increase in AHI. Conclusions: This study does not support a relationship between OSAS and glaucomatous progression. No correlation was observed between OSAS severity and rate of VF loss.

    Abstract: The use of nylon wicks with fenestrations in nonvalved aqueous shunt surgery significantly reduces intraocular pressure (IOP) and glaucoma medication usage in the immediate postoperative period compared with the use of fenestrations alone. Purpose: To compare early postoperative IOP and medication usage in patients undergoing implantation of a nonvalved aqueous shunt device with fenestrations only or fenestrations with nylon wicks. Methods: A retrospective review of all nonvalved aqueous shunt insertions completed by one surgeon (L.W.H.) was completed using current procedure terminology. Patients undergoing Baerveldt or ClearPath 350 mm 2 aqueous shunt insertion with fenestrations only (n=37) or fenestrations with 2 nylon wicks were identified (n=92). All devices were ligated with 7-0 Vicryl (polyglactin) suture, and either 4 fenestrations or 2 fenestrations and two 9-0 nylon wicks were placed anterior to the ligature. Data regarding visual acuity (VA), IOP, number of glaucoma medications, and complications were collected from the preoperative visit just before surgery, postoperative day 1, week 3 (POW3), week 5, and month 2 (POM2). The main outcome measures were VA, IOP, number of glaucoma medications, and complications at all postoperative time points. Results: There was no difference in logMAR VA between the 2 groups at any time point. At POW3, IOP was significantly lower in the wick group (14.6±7.7 vs. 18.1±8.7 mm Hg, P =0.03). Number of glaucoma medications used was significantly reduced in the wick group at POW3 (0.5±0.9 vs. 1.0±1.2, P =0.02) and POM2 (0.7±1.0 vs. 1.4±1.3, P =0.02). There was no significant increase in the overall rate of complications in the wick group, but there was a higher rate of transient hyphema (28% vs. 8%, P =0.02). Conclusions: The use of 2 nylon wicks with fenestrations in nonvalved aqueous shunt device implantation can significantly lower IOP and medication burden while awaiting the dissolution of the ligature suture.

    Abstract: Acute sternoclavicular fracture-dislocation is associated with high-energy trauma and is being increasingly recognized in children 1 . These injuries are associated with compression of mediastinal structures and can be life-threatening 1 . The management of acute sternoclavicular fracture-dislocation includes closed reduction or open surgical stabilization; however, limited success is reported with closed reduction 2,3 . To our knowledge, there are no detailed descriptions of open reduction and suture fixation of acute sternoclavicular fracture-dislocation in children. Description: Following diagnosis of acute sternoclavicular fracture-dislocation, the timing of surgical treatment is determined according to several patient and surgical factors. Among patients with hemodynamic instability, respiratory compromise, or evidence of asymmetric perfusion, surgical treatment is needed on an emergency basis. In the absence of these factors, surgical treatment can be performed on an urgent basis. It is important to communicate with vascular or thoracic surgeons prior to proceeding to the operating room because of the rare case in which advanced surgical access or vascular repair is required. In the operating room, general anesthesia and large-bore intravenous access are required. Patients are positioned supine on a radiolucent table, and a small bump is placed between the scapulae to elevate the medial aspect of the clavicle. The contralateral sternoclavicular joint and medial aspect of the clavicle should be prepared into the sterile field, as well as both sides of the groin in case vascular access is needed. A 6 to 8-cm incision is centered on the medial aspect of the clavicle, extending to the manubrium. Standard dissection to the clavicle is performed, and care is taken to maintain the integrity of the sternoclavicular ligament complex. Circumferential dissection of the medial clavicular metaphysis is usually required in order to mobilize the dislocated fragment. Reduction of the physeal fracture usually requires axial traction and extension of the ipsilateral shoulder with the aid of a reduction clamp on the medial clavicular metaphysis. In some cases, a Freer elevator can be placed between the metaphysis and epiphysis to shoehorn the clavicle from posterior to anterior. Once reduced, the fracture-dislocation is usually stable; however, the reduction is augmented with suture fixation. The sternoclavicular joint capsule should be repaired if disrupted, and the incision should be closed in layers. Postoperatively, the arm is placed in a sling, and range of motion is commenced at 4 weeks. Alternatives: Alternative management of acute sternoclavicular fracture-dislocation includes closed reduction, plate fixation 4 , and ligament reconstruction 5 . Rationale: In our experience, closed reduction is often unsuccessful, which is consistent with the experiences reported by other authors 2,3 . In addition, suture fixation is sufficient and plate fixation is not required because this injury is relatively stable following reduction. Lastly, ligament reconstruction with use of autograft or allograft may be indicated but is more relevant in chronic cases with injury or attenuation of the sternoclavicular ligament complex. Open reduction allows for direct visualization of the fracture reduction, and suture fixation allows for increased stability without the need for hardware or secondary surgical procedures. Expected Outcomes: We expect patients to achieve full range of motion and strength without any joint instability as reported by Waters et al. 3 . Important Tips:

    Abstract: The purpose of this study was to determine the variability in clinical management of tibial tubercle fractures among a group of pediatric orthopedic surgeons. Nine fellowship-trained academic pediatric orthopedic surgeons reviewed 51 anteroposterior and lateral knee radiographs with associated case age. Respondents were asked to describe each fracture using the Ogden classification (type 1–5 with A/B modifiers), desired radiographic workup, operative vs. nonoperative treatment strategy and plans for post-treatment follow-up. Fair agreement was reached when classifying the fracture type using the Ogden classification ( k  = 0.39; P   〈  0.001). Overall, surgeons had a moderate agreement on whether to treat the fractures operatively vs. nonoperatively ( k  = 0.51; P   〈  0.001). Nonoperative management was selected for 80.4% (45/56) of type 1A fractures. Respondents selected operative treatment for 75% (30/40) of type 1B, 58.3% (14/24) of type 2A, 97.4% (74/76) of type 2B, 90.7% (39/43) of type 3A, 96.3% (79/82) of type 3B, 71.9% (87/121) of type 4 and 94.1% (16/17) of type 5 fractures. Regarding operative treatment, fair/slight agreement was reached when selecting the specifics of operative treatment including surgical fixation technique ( k  = 0.25; P   〈  0.001), screw type ( k  = 0.26; P   〈  0.001), screw size ( k  = 0.08; P   〈  0.001), use of washers ( k  = 0.21; P   〈  0.001) and performing a prophylactic anterior compartment fasciotomy ( k  = 0.20; P   〈  0.001). Furthermore, surgeons had fair/moderate agreement regarding the specifics of nonoperative treatment including degree of knee extension during immobilization ( k  = 0.46; P   〈  0.001), length of immobilization ( k  = 0.34; P   〈  0.001), post-treatment weight bearing status ( k  = 0.30; P   〈  0.001) and post-treatment rehabilitation ( k  = 0.34; P   〈  0.001). Significant variability exists between surgeons when evaluating and treating pediatric tibial tubercle fractures.

    Abstract: Proximal humeral fractures are relatively common in pediatric patients. These injuries are usually treated nonoperatively in younger children or children with minimally displaced fractures. However, closed reduction or open reduction followed by percutaneous pinning is recommended for older children with displaced fractures. Percutaneous pinning has several advantages, but there are limited reports of a safe and reliable surgical technique in the literature. Description: Patients are positioned in a modified beach-chair position to allow orthogonal imaging. The injured extremity is draped free from the remainder of the body. Closed reduction, which comprises a combination of traction, abduction, and rotation, is attempted. Internal or external rotation may be required, depending on the fracture line and deforming forces. If an anatomic closed reduction cannot be obtained, a block to reduction should be suspected and open reduction should be performed via a deltopectoral approach. Once the fracture is reduced, two 2.5-mm threaded Kirschner wires from the small external fixator set are used to percutaneously fix the fracture. Any small external fixator set can be used, and if not available, individual threaded wires of similar size can be used. Alternatively, Kirschner wires can be advanced to the fracture site prior to reduction and then advanced into the humeral epiphysis once the fracture is reduced. Care is taken to avoid the axillary nerve, which is reliably within 6 cm of the anterolateral aspect of the acromion, and wires are placed distal to this site. Once pin position has been confirmed radiographically, the construct is secured with pin-to-pin clamps to improve rigidity and further decrease the risk of pin migration. A soft dressing and shoulder immobilizer are placed postoperatively. Patients are followed with biweekly radiographs, and pins are removed in the outpatient office or under conscious sedation at 4 weeks. Leaving pins for a longer period may increase the risk of skin irritation and potentially infection. Alternatives: Alternatives to closed reduction or open reduction and percutaneous pinning include nonoperative management and elastic intramedullary nailing. Nonoperative treatment is a reliable option for most patients. However, it is not suitable for older children with severely displaced fractures because of diminished remodeling potential. Elastic intramedullary nailing is a good option for distal fractures. However, it is not suitable for proximal fractures, and it has been associated with longer operative times and more blood loss than percutaneous pinning. It also requires a second procedure. Rationale: This procedure allows for anatomic fixation of proximal humeral fractures and provides a rigid construct to maintain reduction. It is not technically challenging, requires limited postoperative immobilization, and decreases the risk of a second general anesthetic.

    Abstract: Despite a validated classification system, high-quality multicenter research databases (CSSG/GSSG), and a recent proliferation in publications, early-onset scoliosis (EOS) surgeons have no consensus on standards for surgical treatment. The 21st-century revolution in EOS care has only accelerated, with the arrival of a classification system, magnetically controlled growing rod, nusinersen, and improved nonoperative care (Mehta or Risser casting and compliance-monitored braces). This dizzying pace of change may have outstripped our ability to develop best-practice standards for EOS surgical indications. To learn where consensus is best (and worst) at this moment, we surveyed EOS world thought-leaders on a collection of representative cases. Methods: A 6-case survey was constructed and sent to 20 EOS world thought-leaders. The cases were selected to be representative of the major treatment categories: idiopathic, neuromuscular, syndromic, congenital, thoracic dysplasia, and spinal muscular atrophy (specifically to assess the impact of nusinersen and parasol deformity on surgical planning). Respondents were queried regarding treatment with specific attention to instrumentation and construct when surgery was selected. Responses regarding surgical timing and technique were analyzed for consensus (defined as 〉 80%). χ 2 analysis was performed to evaluate for differences in treatment preferences based on years of experience. Results: The survey response was 100%. Clinical experience ranged from 8 to 40 years (average 23.9 y). There was no consensus on any case. The greatest variability was on the congenital case; the closest to consensus was on the spinal muscular atrophy case. Three or more approaches were selected for all 6 cases; 〉 4 approaches were selected for 5 cases. There is a trend towards screw fixation for proximal anchors. The management of thoracic dysplasia and parasol deformity is far from consensus. Conclusion: The lack of consensus for surgical treatment of 6 representative EOS cases demands a renewed effort and commitment to develop best-practice guidelines based on multicenter outcome data. Level of Evidence: Level V—Expert Opinion.

    Abstract: The field of artificial intelligence has grown exponentially in recent years with new technology, methods, and applications emerging at a rapid rate. Many of these advancements have been used to improve the diagnosis and management of glaucoma. We aim to provide an overview of recent publications regarding the use of artificial intelligence to enhance the detection and treatment of glaucoma. Recent findings Machine learning classifiers and deep learning algorithms have been developed to autonomously detect early structural and functional changes of glaucoma using different imaging and testing modalities such as fundus photography, optical coherence tomography, and standard automated perimetry. Artificial intelligence has also been used to further delineate structure-function correlation in glaucoma. Additional ‘structure-structure’ predictions have been successfully estimated. Other machine learning techniques utilizing complex statistical modeling have been used to detect glaucoma progression, as well as to predict future progression. Although not yet approved for clinical use, these artificial intelligence techniques have the potential to significantly improve glaucoma diagnosis and management. Summary Rapidly emerging artificial intelligence algorithms have been used for the detection and management of glaucoma. These algorithms may aid the clinician in caring for patients with this complex disease. Further validation is required prior to employing these techniques widely in clinical practice.
