Reliability of radiographic assessments of adolescent midshaft clavicle fractures by the FACTS multicenter study group. J Orthop Trauma 2017.

• Li, Y., Donohue, K.S., Willimon, S.C., et al.
• Radiographic measurements of clavicle fracture displacement and shortening have good inter- and intra-rater reliability. The cortex-to-corresponding-cortex measurement of shortening is more accurate than end-to-end and should be used in clinical practice.
• Summary: Currently, when a patient breaks her collar bone, there is no standardized way to review imaging studies and calculate displacement. These measurements are important because they guide decision making regarding the need for surgery. Our team collaborated with other centers in the study group to find reliable ways to measure, evaluate and standardize care of clavicle fractures. 

Adolescent clavicle nonunions: Potential risk factors and surgical management. J Shoulder Elbow Surg 2017.

• Pennock, A.T., Willimon, S.C., Busch, M.T., et al.
• Nonunion is a rare outcome in adolescent clavicle fractures. Predictors of nonunion are male patients who have a displaced fracture through a previously fractured clavicle.
• Summary: This study was conducted to better understand the commonality and rarity of nonunions. Our team collaborated with other centers to identify patients whose clavicles did not heal. This occurrence is very low (less than 15 cases). This study showed that nonunions rarely occur. 

Functional outcomes following nonoperative versus operative treatment of clavicle fractures in adolescents. J Child Orthop 2017.

• Herzog, M.M., Busch, M.T., Willimon, S.C., et al. 
• There are no significant differences in function or patient-reported outcomes between patients treated nonoperatively versus operatively for displaced and shortened clavicle fractures.
• Summary: Some clavicle fractures can benefit from surgical repair, while others can be managed successfully without surgery. Our doctors are not just interested in treating the fractures. We want to know that a patient’s functional outcome is better because of the treatment. This study examines patients who had a clavicle fracture that was treated with or without surgery and tests the strength and endurance of their arms.

Intra-articular physeal fractures of the distal femur: A frequently missed diagnosis in adolescent athletes. Orthop J Sports Med 2017.

• Pennock, A.T., Ellis, H.B., Willimon, S.C., et al.
• Intra-articular physeal fractures of the distal femur are commonly missed, and practitioners must have a high index of suspicion for this injury pattern when evaluating skeletally immature athletes with acute knee injuries.
• Summary: A fracture through the growth plate at the end of the femur (thigh bone) is difficult to diagnose and frequently missed in adolescent athletes. It’s important to have a doctor experienced in sports medicine injuries to make sure athletes recognize these injuries and get the treatment they need. This study was performed in order to better understand these fractures and their growth-related complications.

The use of a transolecranon pin in the treatment of pediatric flexion type supracondylar humerus fractures. J Pediatr Orthop. September 2017.

• Green, B.M., Stone, J.A., Fletcher, N.D.
• A transolecranon pin is one technique to obtain provision reduction of flexion-type supracondylar humerus fractures that may otherwise require open reduction.
• Summary: This injury is a relatively rare, hard-to-treat variant of commonly treated injury. Previously, this injury required an open surgery to realign the bones. Open surgery can mean a longer recovery time, more risk for complications and more pain. Our research showed that our new technique helped avoid open surgery in all cases. This was a small study, but showed the minimally invasive technique to be effective and have positive outcomes for patients.

Descriptive epidemiology of adolescent clavicle fractures: results from the FACTS prospective multicenter cohort study. Orthop J Sports Med 2020;8(5).

• Ellis, H.B., Li, Y., Bae, D.S., Willimon, S.C., Heyworth, B.E., et al.
• Summary: Adolescent clavicle fractures occur most commonly in male athletes as a result of a direct blow to the shoulder. In this multicenter study of 545 teenage patients, approximately 50% of these fractures were completely displaced and the majority of these fractures were successfully managed without surgery.

Outcomes Of Operative Treatment Of Triangular Fibrocartilage Tears In Pediatric And Adolescent Athletes,” Journal of Pediatric Orthopedics, 38(10): e618-622, 2018.

• Fishman F.G., Barbar J, Lourie G.M., Peljovich A.E.
• Summary: TFCC tears are a well-known adult wrist injury, but little has been reported in children. Though these injuries are traditionally associated with distal radius fractures in children, this study reviews the experience in treating these tears in children and adolescents. Nearly all of the tears resulted from injuries sustained during a sports activity, and not from fractures; something previously unreported. Our team reported the findings associated with this injury to raise awareness. Our team also found that 80% of patients returned to their previous level of sport within 4.8 months after surgery while nearly all were satisfied with the results of the surgery. When warranted, surgical treatment of TFCC injuries in our young athletes can reliably help them return back to their level of sport.

Increased hip intracapsular pressure decreases perfusion of the capital femoral epiphysis in a skeletally immature porcine model. J Pediatr Orthop. 2020 Apr;40(4):176-182. doi: 10.1097/BPO.0000000000001284. PMID: 32132447.

• Upasani V.V., Badrinath R, Farnsworth C.L., Jeffords M.E., Hallare J.A., Ahmed S.I., Schrader T.S.
• This study evaluates the relationship between intra-articular hip pressure (IAP) and epiphyseal perfusion pressure (EPP), and its dependency on skeletal maturity to determine if hip pressure has an effect on femoral head avascular necrosis after hip fractures or acute slipped capital femoral epiphysis (SCFE).

• Summary: Post-traumatic femoral head avascular necrosis (AVN) happens when bone tissue begins to die due to lack of blood supply. Hip fractures, dislocations and SCFE have been associated with high rates of AVN. With this study, we found that increased pressure within the hip joint in a young pig with open growth plates led to decreased blood perfusion inside the femoral head. We also found that the decreased perfusion was reversible (in the short term) by decreasing the hip joint pressure. This study is clinically relevant because releasing the pressure of the hip joint (hip capsulotomy) in young patients may help decrease the rate of AVN.

Intraoperative monitoring of epiphyseal perfusion in slipped capital femoral epiphysis. J Bone Joint Surg Am. 2016; 98(12):1030-1040.

• Schrader, T.S., Jones, C.R., Kaufman, A.M., et al. 
• Femoral head perfusion in patients with SCFE can be measured intra-operatively. The presence of femoral head perfusion was predictive of the absence of postoperative osteonecrosis.
• Summary: This novel technique to monitor blood flow to the ball of the hip (femoral head) during surgery for SCFE was developed by Dr. Schrader, Medical Director of the Children’s Hip Program. Demonstrating blood flow to the femoral head during surgery was associated with an absence of osteonecrosis after surgery. This study will help improve patient outcomes.

Arthroscopic management of pigmented villonodular synovitis of the hip in children and adolescents. Ortho J Sports Med 2018.

• Willimon, S.C., Schrader, T.S., Perkins, C.A.
• Pigmented villonodular synovitis (PVNS) should be considered in the differential diagnosis of children and adolescents with atypical presentations of hip pain that fail to respond to treatment for rheumatologic or infectious disorders. Arthroscopic synovectomy of the hip following a timely diagnosis of PVNS produces good outcomes. 
• Summary:PVNS is a noncancerous tumor-like condition that affects the joints—most commonly the knee, hip, elbow and shoulder. PVNS is often difficult to diagnose. Our study examined a series of young patients with PVNS of the hip that had not been previously reported. Historically, these surgeries were open procedures. Our sports medicine surgeons perform these arthroscopically, which usually has a shorter recovery time, less pain and fewer complications compared to more traditional approaches.

Increased hip intracapsular pressure decreases perfusion of the capital femoral epiphysis in a skeletally immature porcine model. J Pediatr Orthop 2020;40(4):176-182.

• Upasani, V.V., Badrinath, R., Farnsworth, C.L., Jeffords, M.E., Hallare, J.A., Ahmed, S.I., Schrader, T.
• Summary: Increased pressure around the hip, caused by bleeding from a fracture or slipped capital femoral epiphysis can result in avascular necrosis (loss of blood flow to a portion of the femur). In this animal study, the increase in pressure was successfully treated with decompression and opening of the hip capsule. This evidence supports opening the capsule and decompressing the increased pressure in the joint when treating children with certain hip fractures.

Comparative cost-utility analysis of postoperative discharge pathways following posterior spinal fusion for scoliosis in non-ambulatory cerebral palsy patients. Spine Deformity Journal. May 18, 2021. 

• Shaw, K.A., Heboyan, V., Fletcher, N.D., Murphy, J.S.
• Summary: Accelerated postoperative discharge (AD) pathways have demonstrated numerous benefits for patients with adolescent idiopathic scoliosis (AIS) after undergoing a posterior spinal fusion (PSF). Although early evidence supports the application of AD pathways over more traditional discharge (TD) approaches for patients with neuromuscular scoliosis, the economic impact of these pathways has not been investigated. This cost-utility analysis demonstrated that the implementation of an AD pathway following PSF for non-ambulatory CP scoliosis is economically more effective. The cost-effectiveness of the AD was maintained despite implant cost variations.

In-hospital opioid usage following posterior spinal fusion for adolescent idiopathic scoliosis: Does methadone offer an advantage when used with an ERAS pathway? Spine Deformity Journal. March 18, 2021.   

• Shaw, K.A., Fletcher, N.D., Devito, D.P., Schmitz, M.L., Fabregas, J.A., Gidwani, S., Chhatbar, P., Murphy, J.S.
• Summary: Intraoperative methadone has been shown to decrease opioid medication required after a posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). No study to date has investigated the effect of methadone on opioid medication requirement when used in conjunction with an enhanced recovery after surgery (ERAS) protocol following PSF. The study concluded that there was no decrease of in-hospital opioid usage when methadone was used with an ERAS protocol. Total opioid usage is correlated with hospital length of stay following the surgery.

Development of consensus-based best practice guidelines (BPG) for postoperative care following posterior spinal fusion for AIS. Spine 2017.

• Fletcher, N.D., Glotzbecker, M.P., Marks, M.C. The Harms Study Group, Newton PO.
• Nineteen clinical practice guidelines are described for the postoperative management of patients following posterior spinal fusion for adolescent idiopathic scoliosis.
• Summary: We are nationally renowned for our pediatric postoperative spinal fusion pathway. Our team was the first to publish our pathway five years ago. In comparing data across our hospitals, we found a 25% decrease in length of stay and no increase in complications due to the implementation of our pathway. Because of the success of the pathway, Nicholas Fletcher, MD, Medical Director of Children’s Spine Quality and Outcomes was asked to lead a team of nationally renowned surgeons to create a best practice guideline for postoperative care following posterior spinal fusion for adolescent idiopathic scoliosis. Most recently, we’ve found that with our pathway sicker kids with more complex conditions also benefited from our guidelines. We saw a 50% decrease in complications and a 25% shorter length of stay for these patients.

• Fletcher, N.D., Andras, L.A., Lazarus, D.E., Owen, R.J., Geddes, B.J., Cao, J., Skaggs, D.L., Oswald, T.S., Bruce, R.W.
• Discharge after posterior spinal fusion for scoliosis may be expedited using a coordinated postoperative pathway without an increase in complications.
• Summary: In order to prove the positive outcomes of Children’s Healthcare of Atlanta’s spinal fusion pathway, we collaborated with Children’s Hospital Los Angeles. When comparing pathways, we found that our patients were released 50 percent sooner with no major difference in complications. As a result, many pediatric hospitals across the country are adopting the spinal fusion pathway created by our team.

Assessment of skeletal maturity and post-operative growth disturbance after anterior cruciate ligament reconstruction in skeletally immature patients: A systematic review. American Journal of Sports Medicine. May 2021. 

• PLUTO Study Group, including, Perkins, C.A., Willimon, S.C., Busch, M.T., et al.
• Summary: Growth disturbance is an uncommon but potentially serious complication after anterior cruciate ligament (ACL) reconstruction in skeletally immature patients. The purpose of this study was to describe how pediatric ACL literature has assessed preoperative skeletal maturity and the amount of growth remaining, and to comprehensively review the incidence, reporting and monitoring of post-operative growth disturbance.

Rates of concomitant meniscal tears in pediatric patients with anterior cruciate ligament injuries increase with age and body mass index. Orthopaedic Journal of Sports Medicine. March 2021. 

• Perkins, C.A., Christino, M.A., Busch, M.T., Murata, A., Egger, A.C., Kelleman, M., Willimon, S.C.
• Summary: Anterior cruciate ligament (ACL) tears are frequently associated with meniscal injury. Risk factors for concomitant meniscal injuries have been studied in the adult population but less so in pediatric patients. Pediatric patients undergoing ACL reconstruction had a 58% incidence of concomitant meniscal pathology. Increasing age and body mass index (BMI) were independent risk factors for these injuries, while no association was found between time to surgery and meniscal pathology.

Early operative versus delayed operative versus nonoperative treatment of pediatric and adolescent anterior cruciate ligament injuries. American Journal of Sports Medicine. March 2021. 

• PLUTO Study Group, including, Perkins, C.A., Willimon, S.C., Busch, M.T., et al.
• Summary: Early and delayed operative treatment achieved satisfactory knee stability. However, delaying anterior cruciate ligament (ACL) reconstruction in pediatric patients younger than 12 weeks old significantly increased the risk of meniscal injuries and irreparable meniscal tears.  Nonoperative management resulted in high rates of residual knee instability, increased risk of meniscal tears and comparatively low rates of return to sports.

Transosseous repair of patellar sleeve fractures: A case series and surgical technique guide. Journal of Knee Surgery. February 2021. 

• Perkins, C.A., Egger, A.C., Willimon, S.C.
• Summary: The purpose of this study is to describe the surgical technique and outcomes of transosseous repair of patellar sleeve fractures in a pediatric cohort. A retrospective review was performed on patients younger than 16 years old who underwent transosseous repair of distal patellar sleeve fractures. Primary outcomes included intact extensor mechanism function and range of motion (ROM) at final follow-up. All patients who began knee ROM  physical therapy within 21 days of surgery obtained full knee ROM. No patients experienced construct failure or extensor lag. Operative management of displaced patellar sleeve fractures with anatomic transosseous suture repair of the sleeve fracture, brief immobilization no more than 21 days, and initiation range of early ROM results in excellent outcomes.

Saucerization and repair of discoid lateral menisci with peripheral rim instability: intermediate term outcomes in children and adolescents.  J Pediatr Orthop 2021;14(1):23-27.

• Perkins, C.A., Busch, M.T., Christino, M., Willimon, S.C.
• Summary: A single-institution retrospective review was performed of consecutive patients less than 18 years of age treated with saucerization and repair for a meniscocapsular tear of a discoid lateral meniscus from 2013 to 2017. Saucerization of discoid lateral menisci with repair of meniscocapsular tears is associated with low rates of revision surgery and good intermediate-term outcomes. 

Allograft augmentation of hamstring anterior cruciate ligament autografts is associated with increased graft failure in children and adolescents. Am J Sports Med. 2019 Jun;47(7):1576-1582.

• Perkins, C.A., Busch, M.T., Christino, M., Herzog, M.M., Willimon, S.C.
• Summary: Hamstring graft sizes in adolescent patients having ACL reconstruction can be variable. If a surgeon obtains a small graft, this study demonstrates that enlarging the graft by folding over the native hamstring tendon has superior results compared to adding allograft tissue to the construct.

Don’t you wish you had fused to the pelvis the first time: a comparison of reoperation rate and correction of pelvic obliquity. Spine 2019;44(8):E465-E469.

• Nielsen, E., Andras, L.M., Bellaire, L.L., Fletcher, N.D., Minkara, A., Vitale, M.G., Troy, M., Glotzbecker, M., Skaggs. D,L.
• Summary: This study established that fusion to the pelvis rather than the lower lumbar spine may be preferable in patients undergoing spinal fusion for neuromuscular scoliosis due to the high operating time and blood loss associated with a revision surgery.

Intra-articular physeal fractures of the distal femur: A frequently missed diagnosis in adolescent athletes. Orthop J Sports Med 2017.

• Pennock, A.T., Ellis, H.B., Willimon, S.C., et al.
• Intra-articular physeal fractures of the distal femur are commonly missed, and practitioners must have a high index of suspicion for this injury pattern when evaluating skeletally immature athletes with acute knee injuries.
• Summary: A fracture through the growth plate at the end of the femur (thigh bone) is difficult to diagnose and frequently missed in adolescent athletes. It’s important to have a doctor experienced in sports medicine injuries to make sure athletes recognize these injuries and get the treatment they need. This study was performed in order to better understand these fractures and their growth-related complications.

Transphyseal ACL reconstruction in skeletally immature patients. The Pediatric ACL: Clinical Evaluation and Management Strategies. Springer. 2018.

• Perkins, C.A., Willimon, S.C., Busch, M. 
• ACL reconstruction in skeletally immature patients with a transphyseal technique is appropriate for adolescents with two or fewer years of remaining skeletal growth.
• Summary: This book chapter discusses the strategy and treatment to reconstruct an ACL in children and young teenagers. Sometimes, treating pediatric ACL injuries like you would an adult’s can be risky and dangerous due to remaining skeletal growth. Adolescent patients are also at higher risk for re-injury. Our sports medicine team includes physical therapists, athletic trainers, sports medicine primary care doctors and orthopedic surgeons. Our goal with ACL rehabilitation is to help patients return to activity based on their recovery and function versus a specific timeframe after surgery.  

Pigmented villonodular synovitis of the knee: An underappreciated source of pain in children and adolescents. J Pediatr Orthop 2018;38(8):e482-e485

• Willimon, S.C., Busch, M.T., Perkins, C.A. 
• Summary: PVNS is a noncancerous tumor-like condition that affects the joints—most commonly the knee, hip, elbow and shoulder. PVNS is often difficult to diagnose. This is the largest published series of pediatric patients with PVNS of the knee. Our sports medicine surgeons treat PVNS arthroscopically, which usually has a shorter recovery time, less pain and fewer complications compared to more traditional approaches.
