Operative Management of Pediatric Physeal Bar Development and Genu Valgum.

Background: Pediatric orthopedic conditions present unique challenges due to ongoing skeletal growth and development. Managing these cases requires addressing both structural anomalies and functional deficits. Care presentation: This case report discusses a 13-year-old male with recurrent left knee pain exacerbated by physical activity. The patient's history of a left knee infection at 1.5 years of age, possibly septic arthritis or osteomyelitis, underscores the long-term consequences of early pathology on skeletal growth and alignment. Imaging studies revealed a distal lateral femur physis bar and genu valgum, necessitating surgical intervention. Management and Outcomes: The surgery involved medial distal femur hemiepiphysiodesis and lateral distal femur bar excision to correct anatomical deformities and restore optimal limb alignment and function. Postoperative rehabilitation, including targeted exercises to improve quadriceps strength, was crucial for functional recovery and reducing the risk of complications such as medial patellofemoral pain. Conclusion: This case highlights the importance of a multidisciplinary approach in managing complex pediatric orthopedic cases.

Comparing the Outcomes of Titanium and Stainless Steel Flexible Nails in Repairing Pediatric Long Bone Fractures.

Background: Traditionally, pediatric femoral fracture treatment favored conservative methods, relying on casting and the inherent bone remodeling ability in immature bones. Surgical intervention was deferred until age 6, as nonoperative approaches often resulted in complications. Titanium elastic nailing (TENS) emerged as an effective treatment for diaphyseal femoral fractures in ages 6 to 16. However, the choice between TENS and stainless steel elastic nailing (SSENS) remains debated due to inconsistent findings. Objective: This study aimed to evaluate the effectiveness of both nailing systems in pediatric long bone fractures. Methods: A retrospective chart review at William Beaumont Hospital Royal Oak included 83 patients aged 6 to 16 treated with TENS or SSENS between January 2011 and January 2021. Data collected encompassed nail related issues, time to fracture union, full weight bearing, and nail removal. Results: In the TENS group (n=29), the average age was 8.8±2.4 years, and the average BMI was 17.2±3.4. The SSENS group (n=54) had an average age of 9.3±2.7 and an average BMI of 19.7±8.4. Time to fracture union for TENS was 93.8±60.5 days, while SSENS was 82.2±40.0 days. Conclusion: This study found no statistically significant differences in nail-related complications, time to fracture union, full weight bearing, or nail removal between TENS and SSENS in pediatric long bone fractures. The choice between these systems should be based on individual circumstances. Limitations include a small sample size and the study's retrospective nature.

The Duration of Symptoms Influences Outcomes After Lumbar Microdiscectomies: A Michigan Spine Surgery Improvement Collaborative.

STUDY DESIGN: Retrospective Cohort. OBJECTIVE: We investigate whether duration of symptoms a patient experiences prior to lumbar microdiscectomy affects pain, lifestyle, and return to work metrics after surgery. METHODS: A retrospective review of patients with a diagnosis of lumbar radiculopathy undergoing microdiscectomy was conducted using a statewide registry. Patients were grouped based on self-reported duration of symptoms prior to surgical intervention (Group 1: symptoms less than 3 months; Group 2: symptoms between 3 months and 1 year; and Group 3: symptoms greater than 1 year). Radicular pain scores, PROMIS PF Physical Function measure (PROMIS PF), EQ-5D scores, and return to work rates at 90 days, 1 year, and 2 years after surgery were compared using univariate and multivariate analysis. RESULTS: There were 2408 patients who underwent microdiscectomy for lumbar disc herniation for radiculopathy with 532, 910, and 955 in Groups 1, 2, and 3, respectively. Postoperative leg pain was lower for Group 1 at 90 days, 1 year, and 2 years compared to Groups 2 and 3 (P < .05). Postoperative PROMIS PF and EQ-5D scores were higher for Group 1 at 90 days, 1 year, and 2 years compared to Groups 2 and 3 (P < .05). CONCLUSION: Patients with prolonged symptoms prior to surgical intervention experience smaller improvements in postoperative leg pain, PROMIS PF, and EQ-5D than those who undergo surgery earlier. Patients undergoing surgery within 3 months of symptom onset have the highest rates of return to work at 1 year after surgery.

Virtual and Augmented Reality in Spine Surgery: An Era of Immersive Healthcare.

In the dynamic realm of spinal surgery, the integration of virtual reality (VR) and augmented reality (AR) technologies is heralding a transformative era. These cutting-edge tools are not only reshaping the training landscape for surgical trainees, offering immersive and interactive experiences but are also enhancing the surgical precision of seasoned professionals in the operating room. While the potential of VR and AR is vast, their adoption is tempered by significant costs and challenges in seamless integration. As the spinal surgery community looks ahead, it becomes imperative to emphasize the validation, reliability, and thorough cost-benefit analysis of these technologies. This article delves into the current applications, benefits, challenges, and future trajectories of VR and AR in spinal surgery, underscoring their pivotal role in the evolution of immersive healthcare.

Subsidence of All-Polyethylene Tibial Components Used in Unicondylar Knee Arthroplasty: A Cohort Study.

INTRODUCTION: Unicompartmental designs and techniques have been developed to preserve bone stock and minimize soft tissue trauma. Early modern designs and techniques have been introduced with little support in the peer-reviewed literature. MATERIAL AND METHODS: From October 2002 to May 2004, 64 consecutive DePuy Preservation unicondylar knee arthroplasties (UKAs) were performed in 56 patients. Two patients died of unrelated consequences, leaving 62 UKAs for review (55 medial, 7 lateral). All procedures were performed through a quadriceps-sparing approach. All components were cemented, including an all polyethylene tibial component. Clinical and radiographic follow-up data were reviewed and analyzed. RESULTS: At an average follow-up of 2.5 years, six (11%) of the medial tibial components have subsided. Of these, four had moderate-to-severe pain, one did require a revision to a total knee arthroplasty (TKA), and another did stabilize. An additional two patients continued to have knee pain (one requiring conversion to TKA), leaving a total of 55 UKAs (89%) functioning well at early follow-up. Additional complications have included four deep vein thromboses, three cardiac issues following the index procedure, one surgical site infection, one intraoperative medial femoral condyle fracture, and one reoperation for loose cement fragments. CONCLUSION: This study demonstrates a high rate of subsidence for all-polyethylene tibial components used in UKA, resulting in pain and failure of the arthroplasty. Despite the less invasive approach, we found complications that are usually associated with TKA surgery as well as those unique to UKA.

Soft Tissue Benign Hand Masses in the First Web Space: A Retrospective Case Series.

INTRODUCTION: Hand masses are fairly common. While most of these masses are either ganglion cysts or benign tumors, masses in the first web space are not rare, and they may in fact represent a variety of lesions. These include both benign and malignant tumors, metastases, or congenital and anomalous structures, and may involve nerves, vascular structures, connective tissue, and joints. METHODS: In this retrospective case series, data on 12 cases of first dorsal web space hand mass treated at our center over a period of five years were collected and analyzed. RESULTS:  Twelve consecutive patients presenting with a first dorsal web space hand mass over a period of five years were reviewed. This represented a group of nine females and three males, with a mean age of 53 years (range = 16-70 years). Seven patients had a mass on the right side and five on the left side. The surgical approach to resect the mass in all 12 patients was dorsal. The most common diagnosis was ganglion cyst (50%), followed by lipoma (25%) and aneurysm (16.6%). There was one case of eccrine spiradenoma. CONCLUSION: First dorsal web space hand masses can encompass multiple different pathologies, and the first web space has an intricate anatomy. Both of these factors mandate a careful approach that includes meticulous preoperative planning with appropriate advanced imaging studies, which helps to make the surgical procedure more efficient and accurate.

Pediatric Humeral Shaft Fracture Nonunion: A Case Report.

Humeral shaft fractures in the pediatric population are a commonly encountered injury in everyday practice. Most patients with these injuries are treated without surgery and go on to have an uneventful recovery. Nonunion of these injuries in the pediatric population has been reported only once in the literature. This case report follows a 13-year-old female after a seemingly standard transverse humeral shaft fracture. The patient was treated with a fracture brace initially. No signs of healing were noted at the eight-week post-injury follow-up. The family elected for continued conservative management until the patient returned at four months post-injury with persistent gross motion at the fracture site and no healing on radiographs. Laboratory testing did show that she has mild-to-moderate vitamin D deficiency, which was addressed. The patient underwent nonunion treatment with open reduction, internal fixation, and bone grafting. She went on to full union with an uncomplicated postoperative course. This case presents an interesting and unique case presentation. This report shows that, while rare, it is a potential outcome of humeral shaft fractures in the pediatric population. This case also demonstrates that using the standard adult operative technique for nonunion treatment with rigid internal fixation and bone grafting in a pediatric patient will lead to full-bone healing.

The Diagnosis and Management of Pediatric Spine Infections.

The management of pediatric spine infections requires a multidisciplinary approach that includes orthopedic surgeons, infectious disease specialists, interventional radiologists, and others. The prevalence of the disease has increased in frequency, virulence, and degree of soft tissue involvement over the past several years; there has also been a resurgence of some types of infections, such as tuberculosis, fungal, and viral pathogens. The diagnosis can often be reached with a detailed history, physical examination, laboratory tests, and imaging studies. Pathologies mimicking infection require a more invasive approach for diagnosis, including core or open biopsy. The treatment of discitis, spondylodiscitis, vertebral osteomyelitis, spinal epidural, and intramedullary abscesses in children is at times complex, and although many infections can be treated non-surgically with antibiotic therapy, some more extensive infections require surgical management. A timely diagnosis is important as it allows the initiation of the appropriate antimicrobial therapy and would decrease the complexity of the subsequent surgical intervention.

Pediatric Calcaneal Tuberosity Avulsion Fracture: A Case Report and Literature Review.

INTRODUCTION: Calcaneus fractures are rare in the pediatric population, and avulsion fracture of the calcaneal tuberosity is even less common. In adults, those fractures are usually associated with poor bone quality, however, this is not the case in children. It is a fracture that requires emergent intervention to prevent devastating skin and soft-tissue-related complications. CASE REPORT: We report a case of a 9-year-old female who had a displaced calcaneal tuberosity fracture with heel skin impending compromise, after a fall at an indoor gymnastic facility. The child had a history of acute lymphoblastic leukemia, diagnosed at age 4, she was in remission at the time of injury. In the present report, besides reporting a rare injury among the pediatric population, we also describe the operative management, the post-operative course, and we review the literature. CONCLUSION: Pediatric calcaneal tuberosity fractures, although rare, can lead to devastating complications if not addressed promptly, and should be treated in an expedited fashion.

Pediatric Obturator Internus Muscle Myxoma.

Intramuscular myxoma is a rare benign tumor that presents as a slow-growing, deeply seated mass confined within a skeletal muscle. Histologically, these lesions most resemble umbilical cord tissue. They mostly occur in people between 40 and 70 years old, with a 57% female predilection. These tumors are very rare in children. Only one pediatric intramuscular myxoma case is reported in the literature. The goal of this study is to report the case of a 13-year-old girl who presented to our hospital emergency department in 2018 with right hip pain, elevated inflammatory markers, and fever; her initial differential diagnosis was hip septic arthritis, pelvic osteomyelitis, and pelvic abscess. A pelvic MRI revealed a well-defined enhancing round lesion in the right obturator internus muscle. The diagnosis was conformed with a CT-guided core biopsy. The patient's symptoms improved with conservative management, and she continues to be doing well 2 years later. Pediatric pelvic intramuscular myxomas are extremely rare; however, they can have a presentation that mimic a more serious condition such as hip septic arthritis, pelvic osteomyelitis, and pelvic abscess and should be considered in the differential diagnosis in a pediatric patient presenting with hip pain.

The distally based sural artery flap for ankle and foot coverage.

The sural artery flap is a distally based fasciocutaneous flap that has many advantages to offer for coverage in the foot and ankle area. It has the largest arc of rotation of all the regional flaps and does not require sacrifice of any major artery, and moderate-to-large-sized defects can be covered adequately. The dissection technique is simple, and donor site morbidity is minimal. We report our experience with 17 cases. Age range was from 13 to 56 years. Ten (59%) defects were posttraumatic, 3 (17%) were related to reconstructive surgery of the foot or tendon Achilles', 2 (11%) resulted from tumor resection, and 1 each were from infection and gunshot wound. The smallest flap was 6 x 4 cm and the largest was 15 x 12 cm, with the average size being 11 x 7.5 cm. In 5 cases, the donor site was closed primarily, and in other cases, split-thickness skin graft was needed. The short saphenous vein was included in the pedicle in all cases. There was no incidence of complete flap necrosis. Follow-up ranged from 3 to 30 months. Two cases (12%) developed partial superficial necrosis. In 1 case, there was partial wound dehiscence that needed debridement and repair. Another case had postoperative discharge, which subsided after removal of the calcaneal plate. None of the patients complained of any functional problem related to loss of sensation along the lateral border of the foot. The sural island flap is a reliable, safe, and easy method of providing soft tissue coverage in the area of the foot and ankle.
