Surgical Treatment of Late Developmental Dysplasia of the Hip in Bladder Exstrophy: A Case Report

CASE

We present a case of an 8-year-old boy with classical bladder exstrophy and a neglected right hip dislocation, exemplifying the risk of missed developmental dysplasia of the hip (DDH) in patients with exstrophy requiring careful orthopaedic oversight.

CONCLUSIONS

When treating patients with bladder exstrophy, physicians and surgeons should be vigilant not to miss associated DDH. If this condition requires surgical treatment, preoperative planning with computed tomography scans is vital to uncovering the complexities arising from abnormal pelvic and acetabular anatomy and ensuring successful treatment outcomes.

Clinical Diagnosis of Slipped Capital Femoral Epiphysis in a Child With Negative Radiological Findings: A Case Report

Slipped capital femoral epiphyses (SCFE) is considered to be a very common disorder among adolescent age group. Multiple risk factors have been reported such as obesity, endocrine disorders, vitamin D deficiency, and panhypopituitarism. The diagnosis of SCFE is important especially in its early stages as this would prevent complications and delay in surgical intervention. The diagnosis is mainly done by radiological imaging and clinical evaluation. However, clinical evaluation is often overlooked. Herein, we present a case of a seven-year-old with SCFE that was diagnosed late due to negative radiological imaging and received late surgical intervention. Therefore, it is recommended that orthopedic surgeons use their clinical sense and examination skills to diagnose SCFE promptly, in order to maintain a short follow-up window to prevent any delay in surgical management and to observe for any progression, even if the radiological findings are normal.

Is the modified Ponseti method effective in treating atypical and complex clubfoot? A systematic review

PURPOSE

In 2006, Ponseti modified the standard technique to treat cases of "atypical" and "complex" clubfoot. To determine the outcomes of Ponseti's modified method to treat complex idiopathic clubfoot patients, we asked the following: (1) What is the deformity correction success rate? (2) What is the relapse rate after the correction? (3) What is the incidence of complications?

MATERIALS AND METHODS

We performed a systematic review by searching the EMBASE, MEDLINE, Cochrane Library, and Web of Science databases from inception to March 1, 2021. All studies on idiopathic, complex, and atypical clubfoot that assessed Ponseti's modified technique were included. Of 699 identified articles, ten met the inclusion criteria. The mean index for non-randomized studies score for the included studies was 11.8 ± 1.7.

RESULTS

Early detection of the deformity and modifying the standard protocol, as described by Ponseti, resulted in a high rate of success. Initial correction occurred in all children, with a mean ankle dorsiflexion of 15°. Relapse occurred often ranging between 10.5 and 55%. The incidence of complications associated with the modified Ponseti method ranged from 6 to 30%.

CONCLUSIONS

Studies using the modified Ponseti technique have shown high initial correction rates and a smaller number of relapses. However, studies with prospective designs and long-term follow-up are required to conclude whether these observations are due to properly performing the modified method or if higher rates of relapse increase with further follow-up.

Complications associated with talectomy in paediatric patients: a comparative retrospective study of two surgical techniques

BACKGROUND

Studies describing the surgical approaches utilized for talectomy and their associated complications are scarce. We aimed to compare the surgical techniques and associated procedures from two groups of patients who underwent talectomy using two approaches. The main purpose of this study was to describe the complications and recurrence rates associated with each technique.

METHODS

Between January 2004 and December 2019, 62 talectomies were performed in 48 pediatric patients with different pathologies. All patient data were reviewed retrospectively, and data of 31 patients were included in the study. The patients were divided into two groups based on the surgical technique used, and the baseline characteristics, along with the post-operative findings, and the intervention types in relation to complications were analyzed.

RESULTS

In the terms of hindfoot varus, midfoot adductus, forefoot supination, and dorsal bunions, the prevalence of these deformities was higher in group (A). Group (B) patients tolerated braces (88.9 %) better than group (A) patients (84.0 %). More adjunct procedures were required in group (A) than group (B) Furthermore, the frequency and types of complications, as well as the need for further surgeries were also higher in group (A). There was a higher rate of recurrence in group A than group B.

CONCLUSIONS

Talectomy is an effective procedure for the treatment of persistent foot deformities despite associated complications. Surgical details and addressing associated deformities with adjunct surgical interventions should be considered.

Functional Outcomes of Talectomy in Pediatric Feet

BACKGROUND

Historically, talectomy has been predominantly performed to operatively treat severely rigid equinovarus feet. A limited number of investigators have studied functional outcomes in pediatric patients posttalectomy. We aimed to assess the outcomes of pediatric patients undergoing talectomy using the American Orthopaedic Foot & Ankle Society (AOFAS) score and a subjective survey of patients' and their caregivers' satisfaction.

METHODS

We performed a retrospective cohort study that included 31 patients with nonidiopathic severely rigid talipes equinovarus, in a single center, using consecutive sampling. All medical records of those patients were reviewed, and relative data were extracted. The AOFAS score was used to measure the outcomes during the last visit (April 2020). Satisfaction was evaluated in a binary manner by questioning the patients and their caregivers if they would undergo the same surgery again for the same result.

RESULTS

Thirty-one patients were included. Myelomeningocele was the primary diagnosis in 13 patients (41.9%), and arthrogryposis was diagnosed in 11 patients (35.5%). Twenty-two patients had bilateral procedures. The mean age at the time of surgery was 6.0 ± 3.0 years, and the mean follow-up was 6.0 ± 1.0 years. Plantigrade feet following the primary surgery were achieved in 88.5% of cases. Postoperatively, braces were well tolerated in 86.5% of patients. Deformity recurrence was observed in 21.2% of patients, and 17.3% of patients required subsequent surgeries. Patients with arthrogryposis had significantly higher AOFAS scores than those with myelomeningocele and other diagnoses (P = .017). Further, patients who tolerated braces had higher AOFAS scores than those who did not tolerate braces (P = .006). However, patients who developed hindfoot varus and dorsal bunion postoperatively had lower AOFAS scores (P = .054 and P = .006, respectively). Patients who had recurrent deformities or required further surgeries also had lower AOFAS scores (P = .025 and P = .015, respectively). Although 17.3% of patients were not able to comment about their satisfaction due to their general medical condition, 63.5% of patients reported that they were satisfied. Furthermore, 75.0% of caregivers were satisfied with the outcomes and their children's functional status posttalectomy.

CONCLUSION

The observed outcomes of primary and salvage talectomies demonstrate the general overall effectiveness of this operative intervention as an end-stage treatment for pediatric patients with severely rigid talipes equinovarus.

Surgical outcomes of open hip reduction with synovectomy for developmental dysplasia of the hip patient with Juvenile idiopathic arthritis: A case report

INTRODUCTION

Developmental dysplasia of the hip (DDH) is a common hip disorder and its association with other musculoskeletal, genetic, and neurological diseases were well described in the literature. Juvenile idiopathic arthritis (JIA) is a rare rheumatological condition, and its presence in a Developmental dysplasia of the hip (DDH) child makes this a very challenging case.

PRESENTATION OF THE CASE

This case report is describing the presentation of 9 months old girl to orthopedic service referred from the pediatric rheumatology clinic after diagnosing her and starting the treatment for Juvenile idiopathic arthritis (JIA). Bilateral neglected Developmental dysplasia of the hip (DDH) - International Hip Dysplasia Institute (IHDI) type 4- was detected during her clinical and radiological assessment, necessitating surgical management after controlling her Juvenile idiopathic arthritis (JIA). The surgical procedure and its clinical and radiological outcomes more than four years after her surgical treatment are described in detail in this report as well.

DISCUSSION

The management of Developmental dysplasia of the hip (DDH) associated with Juvenile idiopathic arthritis (JIA) has no established guidelines in literature. Here, we share our experience in managing such rare cases. We believe that medical control of Juvenile idiopathic arthritis (JIA) before proceeding for open reduction of Developmental dysplasia of the hip (DDH) is the key to successful results.

CONCLUSION

The reported case is uniquely having both Developmental dysplasia of the hip (DDH) and Juvenile idiopathic arthritis (JIA) treated with open reduction, pelvic osteotomy, and femoral shortening resulting in outstanding clinical and radiological outcomes.

Work-related musculoskeletal disorders among Saudi orthopedic surgeons: a cross-sectional study

INTRODUCTION

Studies have addressed the issue of increasing prevalence of work-related musculoskeletal (MSK) pain among different occupations. However, contributing factors to MSK pain have not been fully investigated among orthopaedic surgeons. Thus, this study aimed to approximate the prevalence and predictors of MSK pain among Saudi orthopaedic surgeons working in Riyadh, Saudi Arabia.

METHODS

A cross-sectional study using an electronic survey was conducted in Riyadh. The questionnaire was distributed through email among orthopaedic surgeons in Riyadh hospitals. Standardized Nordic questionnaires for the analysis of musculoskeletal symptoms were used. Descriptive measures for categorical and numerical variables were presented. Student's t-test and Pearson's χ2 test were used. The level of statistical significance was set at p ≤ 0.05.

RESULTS

The response rate was 80.3%, with a total number of 179 of Saudi orthopaedic surgeons (173 males and six females). Of our sample, 67.0% of the respondents complained of having MSK pain. The most commonly reported MSK pain was lower back (74.0%), followed by neck (58.2%). Age and body mass index were implicated in the development of more than one type of MSK pain. Increased years of experience (≥ 6 years) was linked to shoulder/elbow, lower back, and hip/thigh pain. Smoking is widely associated with lower back pain development, whereas physicians who do not smoke and exercise regularly reported fewer pain incidences. Excessive bending and twisting during daily practice have been correlated with increased neck pain.

CONCLUSION

MSK pain was found to be common among Saudi orthopaedic surgeons. Further extensive research should be conducted to understand and analyze the risk factors involved and search for possible improvements to avoid further complications. However, ergonomics education during surgical training could be effective at modifying behaviors and reducing MSK pain manifestations.

Bilateral Valgus Slipped Capital Femoral Epiphysis in an 11-year-old Girl

Valgus slipped capital femoral epiphysis (SCFE) is very infrequent, and it is characterized by a superolateral displacement of the epiphysis on the metaphysis. To date, less than 100 cases of valgus SCFE have been described in the literature. Bilaterality of valgus SCFE is extremely rare, and it presents management challenges to the treating orthopedic surgeons. Herein, we report the case of an 11-year-old Saudi Arabian girl presented to clinic with a one-year history of bilateral hip pain and limping. Past medical history was negative for endocrinopathies, hemoglobinopathies, bone disorders, trauma or radiation therapy to the pelvis. On physical examination, the patient looked tall and obese. On clinical examination, the patient showed a waddling gait and an external rotation on walking. A frog-leg lateral radiograph showed bilateral SCFE with a valgus deformity. The right and left femoral neck-shaft angles measured 154.3 and 148.2 degrees, respectively. Computed tomography (CT) scan suggested a moderate bilateral posterior slippage of femoral heads; the right and left femoral head-neck angles measured 60 and 52 degrees, respectively. A final diagnosis of bilateral valgus SCFE was established. Consequently, the patient underwent bilateral percutaneous in situ pinning with single cannulated screws. Postoperatively, the patient made an uneventful recovery. At one-year follow-up, hip radiograph showed bilateral atypical narrowing of the joint space and suspected chondrolysis and the physis of both proximal femoral heads were fused. On the right side, the fixating screw was penetrating into the articular surface of the femoral head with some osteoarthritic changes. Considering the patient’s worsening situation, it was decided to perform a revisional surgery. The revisional surgery included the removal of bilateral screws and administration of local steroids and analgesics for pain control. Post-revisional surgery at three months, though the patient was limping with a pelvic tilt, she was able to ambulate with the aid of axillary crutches.

Contoured iliac crest allograft interposition for pericapsular acetabuloplasty in developmental dislocation of the hip: technique and short-term results

BACKGROUND

Pericapsular acetabuloplasty procedures have been widely used as an integral component of combined surgery to treat developmental hip dislocation after walking age. The stability of the acetabuloplasty and the maintenance of the acetabular correction will depend on the structural integrity of the iliac crest autograft, which, traditionally, has been inserted as the interposition material. Problems related to the use of an autograft have been encountered by various surgeons-including the authors-namely, graft displacement and resorption, which may necessitate internal fixation or result in revision surgery. To overcome autograft failure, the use of an allograft as the interposition material has been introduced by some surgeons. This study describes the radiologic results of 147 hips treated for developmental hip dislocation by means of a standard protocol of open hip reduction and pericapsular acetabuloplasty with a contoured iliac crest allograft as the interposition material.

METHODS

This retrospective study reviewed the radiographs of 147 hips presenting with late developmental dislocation which were treated by open reduction and a concomitant pericapsular acetabuloplasty using a contoured iliac crest allograft as the interposition material. The minimum follow up period was 2 years. Measurement of the acetabular index (AI) was the main variable. The efficacy of the interposed iliac crest allograft as the main stabiliser of the acetabuloplasty was reflected by the maintenance of the corrected AI during the follow up period. Loss of acetabular correction, graft extrusion or resorption, the need for osteotomy internal fixation, delayed or non union, infection, hip redislocation and avascular necrosis (AVN) as possible complications were documented.

RESULTS

The treatment protocol of a combined open reduction of the hip and pericapsular acetabuloplasty, inserting a contoured iliac crest allograft as the interposition material, resulted in concentrically reduced and stable hips in 96.6% of our cases. The redislocation rate was 3.4%. All of the allografts were completely incorporated at 6 months post-surgery with no graft-related infections. In only two hips was the acetabular correction not maintained. None of the osteotomies required internal fixation for stability, even in older children.

CONCLUSION

We believe that a contoured iliac crest allograft as the pericapsular acetabuloplasty interposition material renders excellent osteotomy stability that eliminates the need for internal fixation and-in the short-term-maintains the correction of the acetabulum achieved intra-operatively.
