Curve Characteristics and Surgical Outcomes in Scoliosis Associated With Childhood Sternotomy or Thoracotomy.

BACKGROUND: The purpose of this study is to describe curve characteristics and postoperative outcomes in patients undergoing spinal fusion (SF) to treat thoracogenic scoliosis related to sternotomy and/or thoracotomy as a growing child. METHODS: A retrospective review of electronic medical records of all patients with Post-Chest Incision scoliosis treated with SF was performed at 2 tertiary care pediatric institutions over a 19-year period. Curve characteristics, inpatient, and outpatient postoperative outcomes are reported. RESULTS: Thirty-nine patients (62% female) were identified. Eighteen had sternotomy alone, 14 had thoracotomy alone, and 7 had both. Mean age at the time of first chest wall surgery was 2.5 years (range: 1.0 d to 14.2 y). Eighty-five percent of patients had a main thoracic curve (mean major curve angle 72 degrees, range: 40 to 116 degrees) and 15% had a main lumbar curve (mean major curve angle 76 degrees, range: 59 to 83 degrees). Mean thoracic kyphosis was 40 degrees (range: 4 to 84 degrees). Mean age at the time of SF was 14 years (range: 8.2 to 19.9 y). Thirty-six patients had posterior fusions and 3 had combined anterior/posterior. Mean coronal curve correction measured at the first postoperative encounter was 53% (range: 9% to 78%). There were 5 (13%) neuromonitoring alerts and 2 (5%) patients with transient neurological deficits. Mean length of hospital stay was 9±13 days. At an average follow-up time of 3.1±2.4 years, 17 complications (10 medical and 7 surgical) were noted in 9 patients for an overall complication rate of 23%. There was 1 spinal reoperation in the cohort. 2/17 (12%) complications were Clavien-Dindo-Sink class III and 5/17 (29%) were class IV. CONCLUSION: Kyphotic thoracic curves predominate in patients with Post-Chest Incision scoliosis undergoing SF. Although good coronal and sagittal plane deformity can be expected after a fusion procedure, postoperative complications are not uncommon in medically complex patients, often necessitating longer postoperative stays. LEVEL OF EVIDENCE: Level III.

Innovative technique for early-onset scoliosis casting using Jackson table.

PURPOSE: Early-onset scoliosis (EOS) can have harmful effects on pulmonary function. Serial elongation, derotation, and flexion (EDF) casting can cure EOS or delay surgical intervention. Most described casting techniques call for specialized tables, which are not available at many institutions. We describe an innovative technique for EDF casting utilizing a modified Jackson table (MJ) and compare results to a Risser frame (RF). METHODS: All patients who underwent EDF casting at our institution between January 2015 and January 2019 were identified and retrospectively reviewed. Patients were stratified by type of table used and clinical and radiographic outcomes were compared. Standard descriptive statistics were calculated. RESULTS: We identified 25 patients who underwent 77 casting events, 11 on an MJ table and 14 on a RF. Mean follow-up was 32 months (range 11-61 months). 28% of patients had idiopathic scoliosis. There was no significant difference in age at initiation of casting (P = 0.3), initial Cobb angle (equivalence, P = 0.009), or rate of idiopathic scoliosis between the MJ and RF groups. There was no significant difference in initial coronal Cobb angle percent correction (equivalence, P = 0.045) or percent correction at 1-year follow-up (equivalence, P = 0.010) between the two groups. There was no difference in cast related complications. There was a significant difference in surgical time, with the MJ group 11 min shorter than the RF (P = 0.005). CONCLUSION: The MJ table is a safe and effective alternative for applying EDF casts under traction without the need for a specialized table. LEVEL OF EVIDENCE: III.

Day of the Week of Surgery Affects Time to Discharge for Patients With Adolescent Idiopathic Scoliosis.

Unnecessary delays in discharge are extraordinarily common in the current US health care system. These delays are even more protracted for patients undergoing orthopedic procedures. A traditional hospital staffing model is heavily weighted toward increased resources on weekdays and minimal coverage on the weekend. This study examined the effect of this traditional staffing model on time to discharge for patients undergoing posterior spinal instrumentation and fusion for adolescent idiopathic scoliosis. Patients undergoing surgery later in the week had a significantly longer hospital stay compared with patients undergoing surgery early in the week (5.5 days vs 4.9 days, respectively; P=.003). This discrepancy resulted in a mean cost increase of $7749.50 for patients undergoing surgery later in the week. A subsequent quality, safety, value initiative (QSVI) was undertaken to balance physical therapy resources alone. Following the QSVI, patients undergoing surgery later in the week had a decreased mean length of stay of 3.78 days (P=.002). Patients undergoing fusion early in the week also had a decreased mean length of stay of 3.66 days (P<.001). There was no longer a significant difference in length of stay between the "early" and the "late" groups (P=.84). This study demonstrates that simply having surgery later in the week in a hospital with a traditional staffing model adversely affects the timing of discharge, resulting in a significantly longer and more costly hospital course. By increasing physical therapy availability on the weekend, the length of stay and the cost of hospitalization decrease precipitously for these patients. [Orthopedics. 2020; 43(1);8-12.].

Endoscopic-assisted epiphysiodesis: technique and 20-year experience.

The aim of the study was to describe the endoscopic-assisted epiphysiodesis technique and review our 20-year experience with it. A retrospective review of 44 patients who underwent proximal tibia and/or distal femur endoscopic-assisted epiphysiodesis was carried out. Only patients who had preoperative and postoperative scanograms with clinical follow-up of at least 6 months were included. The mean length of follow-up was 36.8 months. All patients had radiographic evidence of physeal fusion within 6-12 months from the index procedure. No patient required revision surgery. Endoscopic-assisted epiphysiodesis is safe, effective, and achieves predictable physeal fusion. Advantages over current techniques include reduced radiation exposure and lack of requirement for hardware placement.

Emergency surgical treatment of an ulcerative and hemorrhagic congenital/infantile fibrosarcoma of the lower leg: case report and literature review.

Fibrosarcomas are rare malignant soft-tissue tumors occurring mostly in infants younger than 1 year of age. Fibrosarcomas can ulcerate and cause various complications, which could threaten a fetus in utero or a child in the early neonatal period. We report a unique case of congenital infantile fibrosarcoma of the lower leg, its treatment and pathology. The large expansive and destructive lesion was not appreciated on routine prenatal ultrasound exams at 20 and 33 weeks gestation. The newborn required immediate emergency surgical intervention after delivery to prevent death by hemorrhagic shock. Initial debulking of the tumor was performed and hemostasis was attained on the day of birth. The child was resuscitated and definitive treatment of the leg was deferred until a pathologic diagnosis was obtained. Given the extent of the fibrosarcoma, the lower leg was not salvageable and the patient received a through-the-knee amputation in the neonatal period. The patient is free of disease at 2 years of age.

Kyphectomy in the treatment of patients with myelomeningocele.

BACKGROUND CONTEXT: Myelomeningocele kyphosis is a complex disorder that usually requires surgical intervention. Many complications can occur as a result of this disorder and its treatment, but only surgical correction offers the possibility of restoring spinal alignment. PURPOSE: The purpose of this retrospective study was to summarize the surgical results, complications, and short-term and midterm outcomes for surgical correction of severe kyphosis using a consistent surgical technique. STUDY DESIGN: This was a retrospective review of our database of pediatric patients with myelomeningocele and lumbar kyphosis who underwent kyphectomy with the use of the Warner and Fackler technique. PATIENT SAMPLE: Eleven pediatric kyphectomy cases performed by a single surgeon from 1984 to 2009 were reviewed. OUTCOME MEASURES: Outcome measures include imaging, kyphotic angle measurement, and physical examination. METHODS: Patients underwent the Warner and Fackler technique of posterior-only kyphectomy and bayonet-shaped anterior sacral fixation. RESULTS: The mean extent of kyphosis was 115.6° (range, 77-176°) preoperatively with a correction to 13.0° (range, 0-32°) postoperatively, and a reduction with an average of 102.6° (range, 65-160°), for an 88.7% correction. On an average, 2.0 (range, 1-6) vertebrae were resected. Immediately postoperatively and at follow-up, with an average of 67.2 months (range, 8-222 months), the average kyphosis angle was 13.0° (range, 0-32°). All patients undergoing the procedure were unable to lie supine preoperatively. All patients postoperatively could lie in the supine position. The functional outcome in patients and caretakers was rated very favorably because all patients and caretakers who provided feedback (9 of 11) reported that they were satisfied with the procedure and would undergo the procedure again if given the choice. CONCLUSIONS: This technique has become the most effective surgical reconstruction in myelomeningocele kyphosis. Although significant complications can occur during and after the procedure, most patients had satisfactory postoperative outcomes and restoration of sagittal balance with high patient and parent satisfaction.

Scapular stress fracture initially masquerading as tumor or infection.

We present a case of a scapular stress fracture in a 17-year-old athletic male that was initially thought to be a neoplasm. Radiographs showed a lesion at the neck of the glenoid with aggressive features. A subsequent MRI and bone scan supported a diagnosis of either tumor or infection. However, before a scheduled bone biopsy, a screening chest CT for pulmonary metastases revealed features of a healing stress fracture. The patient ceased intense athletic activity and four weeks later experienced a continued decrease in shoulder symptoms. A followup shoulder CT confirmed a healing fracture. This case illustrates how a stress fracture at an uncommon location may mimic a neoplasm. CT provides complementary information to radiography and MRI and helps establish a definitive diagnosis.

Long-term follow-up of the surgical management of neuropathic arthropathy of the spine.

BACKGROUND CONTEXT: No studies have discussed the long-term surgical management and outcomes of Charcot arthropathy of the spine. This case series presents nine patients treated over 30 years. The study hypothesis was that surgery would reduce instability, pain, recurrence, and the need for revision surgery in the long-term, given previous study findings of successful fusion of Charcot spine in the short-term. PURPOSE: To evaluate the long-term outcomes of surgery for Charcot spine. STUDY DESIGN/SETTING: Retrospective case series. Cases took place at Stanford University Medical Center and Santa Clara Valley Medical Center. METHODS: All patients had either complete paraplegia or dense paraparesis with both major motor and sensory deficits. Seven patients developed Charcot spine after spinal instrumentation for trauma, one after scoliosis repair for meningomyelocele, and one after spinal instrumentation for neuromuscular scoliosis caused by birth injury resulting in C6-C7 quadraplegia. Average time between initial instrumentation and development of Charcot spine was 7.6 years. Two patients underwent posterior fusion alone, six had anterior-posterior fusion, and one was managed with thoracolumbar orthosis. RESULTS: Average follow-up was 14.3 years. Revisions were necessary in 75% (6 of 8) of patients for complications including nonunion, new Charcot joints, recurrent hardware failure, and osteomyelitis. Achieving fusion often required multiple operations, and there were no deaths or neurologic complications. CONCLUSIONS: Long-term follow-up showed a high rate of revision surgery. Solid fusions often resulted in late breakdown or new junctional Charcot arthropathies. Patients initially fused to the lumbar spine instead of the sacrum or pelvis had a higher rate of developing another Charcot joint. Fusion was often difficult with persistent nonunions and functional deficits because of decreased mobility. We recommend that Charcot spine well tolerated without skin, seating problems, or dysreflexia should be cautiously observed with conservative management. For surgical care, we recommend three-column stabilization with either combined anterior-posterior or all posterior approaches with anterior support to obtain and secure greater long-term stability.

Dynamic skeletal traction spica casts for paediatric femoral fractures in a resource-limited setting.

The objective of this study was to compare elastic intramedullary nailing (EIN) with dynamic skeletal traction spica casting (DSTSC) in terms of postoperative radiographic angulations, length of hospital stay, and cost in a resource-limited setting. We prospectively studied 51 children, five to twelve years of age, with femoral fractures treated with either EIN (n = 26) or DSTSC (n = 25). Children treated with EIN had significantly longer hospital stays (17 +/- 8.0 days) than those treated with DSTSC (6.0 +/- 2.5 days). Financial constraints in acquiring supplies caused a significant increase in time from admission to surgery (EIN 9.5 +/- 2.3 days; DSTSC 1.1 +/- 0.3 days), and cost was about 400% higher for EIN compared with DSTSC. At twelve weeks follow-up, all patients in both groups had acceptable radiographic angulations. In resource-limited healthcare settings, DSTSC is an effective alternative to EIN with comparable post-op radiographic angulations, decreased hospital stays, and lower cost.

Dynamic magnetic resonance guided treatment of developmental dysplasia of the hip.

This study demonstrates the feasibility and advantages of near real-time, multiplanar, dynamic magnetic resonance image-assisted treatment of patients with developmental dysplasia of the hip. Pathoanatomy and dynamic blocks to reduction are visualized with anatomic clarity not otherwise possible. Continuous imaging allows accurate assessment and maintenance of optimum positioning throughout the casting procedure. Patient charges for this new technique are less than standard methods of treatment, and the child receives no ionizing radiation.

Personal experiences with overseas volunteerism.

Orthopaedic surgeons often are unaware of the many opportunities and rewards of practicing and teaching as an overseas volunteer in a developing country. Opportunities include participating as a member of an American team under the auspices of groups such as Operation Rainbow; or, one can go alone and practice just with host country personnel through organizations such as Orthopaedics Overseas. Typically, the group missions are short-term assignments of 1 to 2 weeks and are more oriented toward doing surgery. The solo visits typically are 1 month or more and aimed more at teaching. The visits are as rewarding and educational to the visiting volunteer as they are to the host country. The volunteer must be open minded and willing to adapt frequently; he or she will be impressed by the ingenuity and resourcefulness of the host orthopaedists who generally work hard with limited equipment and basic supplies. In general, patients are appreciative and rather stoic. Surgeons from the host country also are grateful and eager to learn and share knowledge.
