Effects of tension band plating on coronal plane alignment of lower extremities in children treated for idiopathic limb length discrepancy.

Purpose: One of the most common treatment methods for moderate limb length discrepancy in children is growth modulation using tension band plating. Coronal plane deformities after tension band plating for limb length discrepancy have been documented as an important complication in articles involving heterogeneous groups consisted of both idiopathic cases and patients with pathological physes. The aim of the study was to determine the rate of coronal plane deformities after treatment of a homogeneous group of idiopathic limb length discrepancy cases with tension band plating and to compare screw constructs of medial and lateral plates. Methods: Patient files were retrospectively reviewed for amount of limb length discrepancy, anatomical femorotibial angle, mechanical lateral distal femoral angle, mechanical medial proximal tibial angle, and inter-screw angles of each plate on both sides of the tibiae and femora. Measurements at each follow-up period were compared to each other. Results: A total of 26 patient files (37 bones) were included to the study. The mean age was 10.5 years. The mean limb length discrepancy was 27.5 mm. Implants were removed after mean 34.5 months. The mean follow-up period was 58.5 months. There was no significant difference in inter-screw angle on each side of the bones at the time of implantation and in lower limb alignments during follow-up. Conclusion: Treatment of mild-to-moderate idiopathic limb length discrepancy with tension band plating in children was found to be safe against any coronal plane deformity during follow-up until skeletal maturity. Level of evidence: Level IV.

Relation of the Sural Nerve and Medial Neurovascular Bundle With the Achilles Tendon in Children With Cerebral Palsy Treated by Percutaneous Achilles Tendon Lengthening.

BACKGROUND: One of the most common treatment options for a short Achilles tendon (AT) in cerebral palsy is percutaneous AT lengthening using 3 hemisections. Because of proximity of neurovascular structures around the tendon, iatrogenic injury to them have been a concern about this technique. The sural nerve (SN) is under risk of injury at the site of the lateral incomplete cut, especially if it is done proximally. The medial neurovascular bundle is under injury risk at medial cuts. The aim of the article was to study the anatomical relations of the SN and medial neurovascular bundle to the AT, and define dangerous levels for injury with the help of magnetic resonance imaging (MRI). METHODS: Patients operated for percutaneous Achilles lengthening were called for MRI investigation of the SN and medial neruvascular bundle integrity and their anatomical relation with the AT. The distance of 5 mm was taken as the threshold for increased risk of injury. Measurements were done on MRI at each cm from the insertion of the tendon on both medial and lateral sides, and at the level of the middle cut. RESULTS: Thirty ankles operated and followed at least 1 year were included to the study. On the medial side, the tibial nerve, and the posterior tibial artery lied more than 5 mm away from the tendon at all levels in all patient. On the lateral side, the first 4 cm were relatively safe for the middle lateral cut, while increased risk of SN damage was detected in more proximal levels. Overall, 6 of 30 ankles had radiographically detectable SN injury. CONCLUSIONS: The first 4 cm of the AT on the lateral side was detected to be safe for the middle lateral directed cut, while whole tendon length were found to be safe for the first and the third cuts of the percutaneous Achilles lengthening surgery using 3 hemisections in children with cerebral palsy.

Intraoperative neuromonitoring during distal femoral extension osteotomy in children with cerebral palsy.

The most common treatment method for a fixed knee flexion contracture more than 10 degrees in cerebral palsy (CP) is distal femoral extension osteotomy (DFEO). However, a serious complication after a DFEO is neurological impairment. Its rates were reported as 5- 40%. Intraoperative neuromonitoring (IONM), widely used in spinal surgery and in other fields, is a valuable tool to define any neurological injury during operation. The aim of our study was to determine surgical steps with risk of neurological injury and to report if precautions would be effective in recovering signal loss. We performed IONM during DFEO of 23 knees of 12 children with CP. IONM was performed by recording somatosensory evoked potentials, transcranial motor evoked potentials and free-run electromyography during defined steps throughout the surgery. Preoperative and postoperative popliteal angles, flexion contractures and physeal posterior distal femoral angles were evaluated. We detected alert signals at osteotomy or manipulation steps of surgeries of all patients. We observed persistent alert signals in two cases (2 out of 23 knees; Group 2). In this group, the action potentials recovered only after 5 and 10 degrees of undercorrection at the osteotomy sites. Alert signals disappeared after a brief period of waiting in other cases. Throughout mean 37 months of follow-up, none of our patients experienced any neurological complication. The study concludes that the surgical steps in DFEO with a higher risk for a neurological complication were the osteotomy and manipulation steps. Alert signals were detected with the help of IONM, and preventive measures were effective in recovering neuromonitoring recordings.

The Coexistence of Spontaneous Femoral Nerve Palsy and Developmental Dysplasia of the Hip in a Breech-Presenting Newborn: A Rare Case Presentation.

CASE: In this report, we present an infant who was diagnosed with femoral nerve palsy (FNP) and developmental dysplasia of the hip (DDH) on the same side after delivery. The patient was treated with hip alternative abduction orthosis, which did not force hip flexion with satisfactory results. CONCLUSION: FNP in newborns with DDH is usually described as a possible complication of the Pavlik harness treatment. However, there is only one report that presents 2 cases. Our objective is to raise awareness of this very rare condition because performing an early intervention is vital to achieving an optimal therapeutic result.

Retro-patellar approach in telescopic nailing of the tibia in children with osteogenesis imperfecta.

PURPOSE: Telescopic intramedullary nailing (TN) has become the main choice of treatment in children with osteogenesis imperfecta (OI). The classical parapatellar tibial nailing technique poses difficulties in maintaining reduction, insertion of the nail and fluoroscopic imaging. Also, deformities of the proximal tibia in relatively small children with OI can be problematic for tibial nailing. In this report, we present the retro-patellar approach in tibial TN of children with OI as an alternative to the classical approach and report the early radiographic and clinical results of our patients. METHODS: The nail is inserted through a skin incision proximal to the patella, passing inside the patellofemoral joint while the knee is positioned to 15° to 20° of flexion. In total, 30 tibiae of 15 patients had been operated and were reviewed after at least one year of follow-up. Any complications, such as implant failure, joint damage or instability, malunion, nonunion or refracture, were recorded. RESULTS: The mean age of our patients was 8.5 years, and the mean follow-up period was 27 months. There were no complaints involving the knee. All patients showed complete union without any implant failure or refracture. We did not observe any nail protrusion, bending or loss of correction during the procedure. CONCLUSION: The retro-patellar approach for tibial TN appears to be safe and effective in patients with OI. LEVEL OF EVIDENCE: IV.

How the COVID-19 pandemic is affecting paediatric orthopaedic practice in Turkey.

PURPOSE: Changes to routine clinical approaches during the corona virus disease 2019 (COVID-19) pandemic are necessary to decrease the risk of infection in patients and healthcare providers. Because the treatment of many conditions is time sensitive, it is crucial to modify the management of paediatric orthopaedic cases by minimizing any subsequent morbidity. Our purpose was to describe the different measures and management strategies that have been applied by paediatric orthopaedic surgeons and to show how paediatric orthopaedic practice is affected in Turkey. METHODS: All active practicing members of the Turkish Society of Children's Orthopedic Surgery (TSCOS) were contacted via telephone and asked to fill out a survey (24 questions). For participants, either an email or web link was sent to their mobile phones. An online survey generator was used. RESULTS: A total of 54 survey responses were collected, for a response rate of 55%. In all, 62% reported a 75% decrease in their outpatient frequency, whilst 75% reported a 75% decrease in their surgery frequency. A total of 86% of the performed surgeries were emergency cases. None of the participants performed elective surgeries, and 61% did not have the consent form specific to COVID. Choice of protective measures have changed considerably; 96% stated that they needed an algorithm to follow for situations such as pandemic. CONCLUSION: This national survey revealed that the COVID-19 pandemic has had a detrimental effect on paediatric orthopaedic practice and practitioner response varies in terms of reactions and precautions. The necessity of creating a protocol based on what we have learned must be taken into consideration. LEVEL OF EVIDENCE: V.

The split transfer of tibialis anterior tendon to peroneus tertius tendon for equinovarus foot in children with cerebral palsy.

OBJECTIVE: The aim of this study was to analyze the results of the split anterior tibialis tendon transfer (SPLATT) to peroneus tertius (PT) for equinovarus foot deformity in children with cerebral palsy (CP). METHODS: The medical records of 25 ambulatory CP patients (mean age: 8.7±3.2 years, range: 4-16 years) with equinovarus foot (33 feet), who underwent SPLATT to PT surgery between 2014 and 2016, were retrospectively reviewed. A senior surgeon performed all the surgical procedures. SPLATT was performed as part of a single-event multilevel surgery for the lower limb, and the concomitant procedures on the same extremity were recorded. The patients who required any additional foot or ankle surgery that could affect the clinical outcome (except heel cord lengthening) were excluded from the study. The Kling's College Criteria were used to evaluate the procedural outcome of the foot position and gait, and the associated complications were recorded. RESULTS: The mean follow-up time was 28.8±5 months (range: 24-42 months). The postoperative Kling scores were excellent for 27 feet of the patients who had a plantigrade foot, without fixed or postural deformity, in a regular shoe, having no calluses; good for 5 cases for those who walked with less than 5° varus, valgus, or equinus posture of the hind foot, wearing regular shoes, having no callosities; and fair for 1 case for those who had recurrence of the deformity. There was only one wound detachment, which was treated with wound care and dressing. None of the patients had overcorrection, infection, or bone fracture. CONCLUSION: The dynamic SPLATT to PT surgery for the management of the equinovarus foot deformities in the CP patients is a safe and less complicated surgical alternative with a good functional outcome. It is a safe and effective treatment method for the management of equinovarus foot deformities in CP. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

Spinopelvic alignment does not change after bilateral total hip arthroplasty in patients with bilateral Crowe type-IV developmental dysplasia of the hip.

OBJECTIVE: This prospective study aimed to evaluate the changes in the sagittal alignment after total hip arthroplasty (THA) in patients with hip osteoarthritis (OA) secondary to Crowe type-IV developmental dysplasia of the hip (DDH) and whether THA would contribute to the relief of low-back pain (LBP). METHODS: A total of 27 patients (2 men and 25 women) with bilateral hip OA secondary to Crowe type-IV DDH were enrolled in this study. Their mean age at the time of surgery was 40,36±12,35. All patients underwent simultaneous, bilateral THA between January 2015 and December 2016. Clinical assessment included Oswestry disability index (ODI) score and Harris hip score (HHS), and pelvic incidence (PI), sacral slope (SS), lumbar lordosis (LL), and pelvic tilt (PT) were measured from radiographs. RESULTS: Preoperatively, all the patients had hip and low-back pain. Preoperative and final follow-up ODI scores were 48.3 and 3.9 (p=0.000), respectively. HHS changed from 43.54 to 92.68 (p=0.000). PT and PI significantly changed from -20.4°±20.4° to 3.2°±16.7° (p=0.001) and from 26.6°±35.1° to 47.4°±17.9° (p=0.001), respectively. There were no significant differences regarding the SS and LL measurements. Age or limb-length discrepancy was not significantly associated with the spinopelvic alignment measurements. CONCLUSION: Restoring the function of the hip with THA is shown to improve hip-associated LBP, but the accompanying hyperlordosis does not change. THA in patients with bilateral Crowe type-IV hips relieves hip pain as well as associated LBP. Hyperlordosis of the lumbar vertebra does not change after surgery, but PI and PT changes are observed; this improvement might have a role in the relief of LBP.

Femoral derotation osteotomy in children with cerebral palsy using the pediatric proximal femoral nail.

We designed a pediatric proximal femoral nail (PPFN) to overcome fixation method-related complications when performing femoral derotation osteotomy in cerebral palsy patients. Preliminary results of cerebral palsy patients who underwent femoral derotation osteotomy fixed using PPFN to treat in-toeing were evaluated. Sixteen patients with a mean age of 10 years were included. Mean follow-up duration was 36 months. There was no significant difference in the follow-up neck-shaft angle and articulotrochanteric distance values (P = 0.2 and 0.3). PPFN provides stable fixation, early weight-bearing, reduces soft-tissue disruption while limiting the complications due to fixation technique.

Using a corkscrew-tipped telescopic nail in the treatment of osteogenesis imperfecta: a biomechanical study and preliminary results of 17 consecutive cases.

High complication rates were reported with the telescopic nail technique systems. To overcome such technical difficulties, we designed a corkscrew-tipped telescopic nail (CTTN). We biomechanically compared its pullout strength with that of two other tip designs. We used CTTN in 17 patients with osteogenesis imperfecta and reported their preliminary results. Average patient age was 82.6 months, and mean follow-up was 32.0±6 months. Telescoping and osteotomy site healing were assessed using radiological studies. Successful telescoping with event-free osteotomy site healing was achieved in 94.1% of patients; limited telescoping and delayed union were detected in one case each. Our results show that CTTN provides sufficient pullout strength and reduced complication rates compared with other designs.

Minimally invasive plate osteosynthesis for tibial derotation osteotomies in children with cerebral palsy.

OBJECTIVE: Tibial derotation osteotomy can be used in the treatment of rotational deformities in case of ineffective conservative management. Our aim was to evaluate the results of the patients who underwent minimal invasive plate osteosynthesis for tibial derotation osteotomies. METHODS: Total of 16 patients (17 procedures) were included in this study. Mean age was 11.5 (3-25) years. We clinically assessed the tibial torsion by measuring the thigh-foot angle (TFA). No immobilization was used postoperatively and range of motion exercises were begun immediately. The patient was allowed weight-bearing activity, as tolerated, when callus formation was seen on the radiographs, at approximately three to four weeks after surgery. RESULTS: The mean follow-up time was 27.5 months. Mean preoperative and follow up TFA were 27° of internal rotation and 3.74° of external rotation, respectively. A mean of 22.3° improvement was achieved postoperatively. There was only one wound detachment, which was accepted as a complication and healed with local wound care. CONCLUSIONS: The recurrence risk and correction loss can be decreased with plate-screw fixation. Minimal invasive surgery would also decrease the risk of wound complications. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

Surgical reconstruction of hip subluxation and dislocation in children with cerebral palsy.

OBJECTIVES: This study aims to review the efficacy of femoral varus derotation osteotomy (VDRO) and Dega transiliac osteotomy in the treatment of hip subluxation and dislocation of cerebral palsy (CP) patients. PATIENTS AND METHODS: This retrospective study included 25 hips of 22 CP patients (9 males, 13 females; mean age 8.7 years; range 4 to 18 years) who were operated due to hip subluxation and dislocation between July 2010 and December 2015. The mean follow-up period was 36.1±10.4 months (range, 20 to 65.6 months). Femoral VDRO and Dega transiliac osteotomy were performed in all cases. None of the patients were administered cast immobilization postoperatively. Patients were evaluated clinically with gross motor function classification system preoperatively and at the follow-up period. Acetabular index (AI), migration percentage (MP), and neck-shaft angle (NSA) were measured and documented by pelvic radiographs taken pre- and postoperatively and at the follow-up period. Intra- and postoperative complications were recorded. RESULTS: Gross motor function classification system scores improved in 16 patients. Mean AI was 33.2° preoperatively and 20.4° postoperatively. In preoperative period, MP and NSA were 72.7% and 160°, respectively, which improved to 24.3% and 130°, respectively, postoperatively. The postoperative improvement in AI, NSA and MP were statistically significant (p<0.001). We performed revision surgery due to implant failure in two patients and detected hip subluxation due to increased pelvic obliquity in one patient who had thoracolumbar scoliosis. CONCLUSION: In CP patients, reconstruction of hip subluxation and dislocation with femoral VDRO and Dega transiliac osteotomy establish femoroacetabular congruency. Without any cast immobilization, early physical therapy is encouraged for immediate recovery.

Surgical correction of hallux valgus deformity in children with cerebral palsy.

OBJECTIVE: This study aimed to present a treatment algorithm for the correction of the hallux valgus deformity in Cerebral Palsy (CP) patients and to discuss the outcomes based on our clinical and radiological results. METHODS: 29 patients (45 feet) were included in the study. The mean age of the patients at the time of the surgery was 14 (range 6-22) years. The mean follow-up was 33 (range 22-59) months. A reconstructive procedure was performed on 19 patients (27 feet); a soft tissue surgery and exostectomy of the bunion in six patients (11 feet); and MTP joint arthrodesis in four patients (7 feet). The hallux valgus angle (HVA) and the anteroposterior intermetatarsal angle (IMA) were used for radiologic evaluation and the DuPont Bunion Rating Score was used for clinical evaluation. RESULTS: The follow-up period was 36 (range 22-59) months in reconstructive group, 27 (range 24-29) months in soft tissue group, and 29 (range 23-41) months in MTP arthrodesis group. Significant improvements were detected in hallux valgus angle in three groups postoperatively but in soft tissue group correction loss was observed during follow up. Best results were achieved in arthrodesis group and worse in soft tissue group in terms of clinical evaluation. CONCLUSION: According to our results isolated soft tissue procedures are ineffective in CP patients. Soft tissue procedure combined with metatarsal osteotomy has satisfactory results. LEVEL OF EVIDENCE: Level IV, therapeutic study.

High-Riding Congenital Hip Dislocation: THA With Unilateral vs Bilateral Transverse Femoral Shortening Osteotomy.

BACKGROUND: We argue that 1-stage bilaterally total hip arthroplasty (THA) could be acceptable in bilateral coxarthrosis because of high-riding developmental dysplasia of the hip (DDH). METHODS: Sixty-nine cases (51 patients) of high-riding DDH in patients who underwent THA from 2010 to 2013 were reviewed. Patients were divided into 2 groups: unilateral (group 1) and 1-stage bilateral surgery (group 2). The clinical measurements were the visual analog scale and Harris Hip Score. RESULTS: The average follow-up was 37.3 months for group 1 and 38.8 months for group 2. The hospital stay time was 5.2 days in group 1 and 6.2 days in group 2 (P = .334). The mean Harris Hip Score and visual analog scale score were improved significantly after surgery for both groups, and there was no statistically significant difference (P = .988). There was no difference between groups 1 and 2 in terms of complications (P = .137). CONCLUSION: Our data confirm that 1-stage bilateral transverse osteotomy with THA is an effective method as unilateral and it does not increase the length of patients' hospital stays and features a low risk of postoperative complications in the treatment of patients with high-riding DDH.

What Determines the Success of Closed-Wedge High Tibial Osteotomy: Severity of Malalignment, Obesity, Follow-up Period, or Age?

OBJECTIVES: High tibial osteotomy (HTO) is a well-established procedure for the treatment of medial knee osteoarthritis originating from malalignment of the lower extremity. The current study was designed to evaluate the clinical and radiographic results of closed-wedge HTO for the treatment of medial knee osteoarthritis and to reveal factors affecting the outcome. METHODS: A retrospective study was conducted with 138 patients who were operated on for medial knee osteoarthritis between 2000 and 2007 using closed-wedge HTO. Preoperative and follow-up physical examination findings, body mass index (BMI) values, and Hospital for Special Surgery (HSS) and Lysholm knee scores were reviewed. Radiographic evaluation included measurement of the mechanical axis preoperatively and the most recent follow-up orthoroentgenograms. The follow-up knee scores were evaluated according to preoperative mechanical axis, obesity, age, follow-up period, and gender of the patient. The mechanical axis measurement was assessed based on obesity, age, and follow-up period. RESULTS: The mean preoperative and latest follow-up mechanical axis was 4.92o±4.24o varus and 3.43o±3.74o valgus, respectively (p=0.0001). Improvement in the Lysholm (p=0.0001) and HSS (p=0.0001) knee scores was significant. The preoperative mechanical axis, obesity, follow-up period, and gender had no negative effect on the follow-up knee scores, whereas a preoperative age over 50 years had a negative effect on the follow-up knee score. Obesity and the length of the postoperative follow-up period did not have a negative effect on the postoperative mechanical axis, whereas a preoperative age over 50 had a negative effect on the postoperative mechanical axis. CONCLUSION: The results of this study suggest that medial knee osteoarthritis may be treated successfully with closed-wedge HTO. The analysis indicated that factors such as obesity, the degree of preoperative deformity, and gender do not adversely affect the success of treatment. However, a preoperative age over 50 adversely affected the outcome.

Management of persistent coccydynia with transrectal manipulation: results of a combined procedure.

OBJECTIVE: We compared the results of manual therapy combined with steroid injection with single steroid injection in the treatment of persistent coccydynia. PATIENTS AND METHODS: Combined therapy was performed in 21 patients (Group 1) and steroid injection in 23 patients (Group 2). We compared two groups and investigated the combined therapy group in details. Patients were classified according to the underlying cause, BMI, anatomic type of coccyx and duration of symptoms (< 6 or ≥ 6 months). RESULTS: Mean age was 30.5 years at the time of procedures. Mean followup time was 27.8 months. VAS scores were decreased in both groups but combined therapy group had much more better results. Complete pain relief was achieved in 61.9% of patients in Group 1 whereas it was only 17.4% in Group 2. In 23.8% of Group 1, the VAS score was significantly decreased but the feeling of uncomfortability persisted. This was 73.9% in Group 2. We had no relapse in Group 1 but in Group 2 the relapse rate was 56.5%. Underlying cause, body mass index, anatomic type of coccyx and duration of symptoms had no effect on results. CONCLUSION: Manual therapy combined with steroid injection would be an alternative method in case of persistent coccydynia. It is a safe and easy option before surgical treatment.

Management of knee rheumatoid arthritis and tibia nonunion with one-stage total knee arthroplasty and intramedullary nailing: A report of two cases.

Total knee arthroplasty (TKA) is a surgical procedure which is widely used in the treatment of gonarthrosis secondary to rheumatoid arthritis (RA). The incidence of stress fractures in tibia in the patients with RA is higher compared to normal patients. In this study, we report two cases of TKA and intramedullary nailing in RA patients with severe knee arthritis and tibial nonunion. Both patients had a satisfactory clinical outcome with radiological healing of the tibial fracture.

Atelosteogenesis type III: orthopedic management.

Atelosteogenesis type III is a rare autosomal dominant skeletal dysplasia caused by mutations in the synthesis of the protein filamin B (FLNB). The mutation in the gene coding for FLNB causes the osteochondrodysplastic features of this disorder. Clinically, osteochondrodysplasia causes unbalanced skeletal maturation and absent or mostly hypoplastic bones, such as the pelvis, vertebrae, ribs, or long bones. In the literature, an orthopedic management for this disorder has not been well described. We report the case and orthopedic management of a 6-year-old female patient with atelosteogenesis type III after 3 years of follow-up.

Risk Factors of Refracture and Morbidity During Removal of Titanium Pediatric Proximal Femoral Locking Plates in Children With Cerebral Palsy.

BACKGROUND: Pediatric proximal femoral locking plates (PFLPs) are widely used when performing proximal femoral osteotomy in children with cerebral palsy (CP). The purpose of this study is to report the difficulties and risk factors of titanium PFLPs removal in CP. METHODS: PFLP removal was performed in 58 hips of 33 patients (17 males, 16 females). The mean age at the time of surgery (plate removal) was 10.9 (range, 5.7 to 19.2) years. The patients were divided into 2 groups as group 1 and 2, if any difficulty was observed during surgery or not. RESULTS: Difficulty was not detected in 42 (72.4%) hips (group 1). Difficulties were encountered in 16 (27.6%) hips (group 2). A total of 364 screws were used (259 in group 1, 105 in group 2). The mean plate screw density ratios were 0.88 in group 1 and 0.94 in group 2. The difference between group 1 and 2 was statistically significant. The mean duration between the insertion and removal of the PFLP was 14.9 months (11.9 mo in group 1, 22.7 mo in group 2). The difference between group 1 and 2 was statistically significant. The screw heads were cut and the shafts were left in the bone in 4 hips (4 screws); 3 of these 4 screws were calcar screws. Therefore, calcar screw application can be accepted as a handicap for screw removal. CONCLUSIONS: As a conclusion, this study suggested that difficulty in titanium PFLP removal in CP is common and PFLP removal is not a harmless procedure. A longer time from internal fixation to removal, increased plate screw density ratio, and calcar screw application are risk factors for difficulties in titanium PFLP removal in CP. LEVEL OF EVIDENCE: Level III.

A rare localization of osteoid osteoma ­ Presentation of two cases.

Introduction: Osteoid osteoma is a benign osteoid-forming tumor generally localized to the long bones, is rarely localized in the hand and the major symptom is intermittent pain. This study aims to present two patients who were operated on for metacarpal osteoid osteomas. Case Outline: A 16-year-old female patient and an 18-year-old male patient were operated on for metacarpal osteoid osteomas. The major symptom was intermittent pain for both patients. After surgical excision of the niduses, the complaints resolved in both cases. Conclusion: In the case of high suspicion for osteoid osteoma, computed tomography or magnetic resonance imaging should be performed due to the risk of negative radiographic findings. Surgical excision is curative and a safe method of treatment.
