Vertebral Anomalies Research Articles

Functional and radiological outcomes following craniovertebral junction surgery.

Craniovertebral junction (CVJ) pathologies include atlantoaxial instability/deformities resulting in myelopathy, respiratory failure, and even death. Here, we describe the indications, preoperative planning, and intra-operative/postoperative complications following surgical management of CVJ anomalies. A prospective analysis of 34 patients with CVJ pathology was evaluated between 2015 and 2022. Their various etiologies included atlantoaxial instability, trauma, tuberculosis, Down's syndrome, Morquio syndrome, os odontoideum, and atlantoaxial abnormalities. Clinical outcomes were assessed using the American spinal injury association (ASIA) impairment scale score and Benzel's modified Japanese Orthopedic Association (mJOA) score. Surgical assessments included length of hospital stay, operative time, blood loss, and intraoperative postoperative complications. Radiological parameters included fusion (i.e., implant loosening/implant failure), preoperative/ postoperative atlanto-dens interval (ADI), clivus canal angle (CCA), and space available for cord (SAC). Five patients were managed conservatively, while 29 patients had surgery. Operations included occipitocervical fusion (14 patients), C1-2 fusion (10 patients), C1-2 transarticular screw fixation (four patients), and one patient underwent anterior corpectomy decompression/fusion. Seven patients had vertebral artery anomalies, and 13 patients had atlantoaxial abnormalities. At the final follow-up, atlantoaxial instability (i.e., mean preoperative ADI of 6.6 ± 2.3 mm) was restored to 4.2 ± 0.6 mm, significant cord compression (i.e., with mean SAC of 8.3 ± 2.9 mm) was relieved to 17.2 ± 1.6 mm, and the mean preoperative CCA (i.e., 130.2 ± 15.3) was improved to 143.3 ± 8.3°. There was also a statistically significant improvement in the ASIA scale and mJOA score. Surgical management of CVJ abnormalities requires expertise and meticulous planning to avoid devastating complications such as wound dehiscence and catastrophic vertebral artery injury.

The prevalence of anomalies in the lumbar spine in the Turkish male population

Aims: It was aimed to determine the prevalence of lumbosacral anomalies in young male population.
 Methods: 56.798 male patients, between 18-49 years old, were included in this study during their medical screening in Dışkapı Yıldırım Beyazıt Training and Research Hospital from July 2016-July 2020. The presence of spina bifida occulta (SBO) and transitional vertebrae (TV) anomalies were recorded in the candidates. SBO patients were evaluated according to their S1 and L5 origins, and TV patients were evaluated separately according to sacralization and lumbarization. We identified transitional vertebrae by counting down from the last thoracic vertebra on the AP X-rays, then if necessary looking at the lateral view for confirmation. If hypoplastic ribs were identified, the vertebra immediately beneath would be designated as L1. Castellvi types I, II, III, and IV were included as transitional states.
 Results: 56798 patients were evaluated retrospectively. The mean age of the patients was 23.28 (18-49 years). Radiological anomalies were detected in 2577 (4.5%) of 56798 cases. No radiological anomaly was observed in other cases. Spina bifida occulta was detected in 1478 (2,6%) patients. Lumbosacral transitional vertebrae were detected in 1099 cases (1.9%). 745 (1.3%) of these anomalies are sacralization and 354 (0.6%) of them are lumbalization.
 Conclusion: In the light of this information, we think that knowing the frequency of lumbosacral anomalies, especially LSVT, in our society should be considered in the evaluation before spinal surgery operations.

Indian patients with CHST3-related chondrodysplasia with congenital joint dislocations.

CHST3-related chondrodysplasia with congenital joint dislocations (CDCJD, #MIM 143095), is a rare genetic skeletal disorder caused by biallelic loss of function variants in CHST3. CHST3 is critical for the sulfation of chondroitin sulfate. This study delineates the clinical presentation of nine individuals featuring the key symptoms of CDCJD; congenital joint (knee and elbow) dislocations, short trunk short stature progressive vertebral anomalies, and metacarpal shortening. Additional manifestations include irregular distal femoral epiphysis, supernumerary carpal ossification centers, bifid humerus, club foot, and cardiac abnormalities. Sanger sequencing was carried out to investigate molecular etiology in eight patients and exome sequencing in one. Genetic testing revealed five homozygous variants in CHST3 (four were novel and one was previously reported). All these variants are located on sulfotransferase domain of CHST3 protein and were classified as pathogenic/ likely pathogenic. We thus report on nine individuals with CHST3-related chondrodysplasia with congenital joint dislocations from India and suggest monitoring the health of cardiac valves in this condition.

Substantial incidence of bladder dysfunction in patients with VACTERL association: Implications for surveillance.

VACTERL association is defined as the nonrandom co-occurrence of a minimum of three of the following six key components: Vertebral anomalies, Anal atresia, Cardiac malformations, Tracheo-Esophageal fistula, Renal anomalies, and Limb abnormalities. Patients presenting with two components may also belong in the same spectrum. Additional components have been associated with VACTERL defects, including single umbilical artery, tethered spinal cord (TSC), and genital malformations. We observed a significant proportion of patients with bladder dysfunction (often called neurogenic bladder in the medical record) when reviewing a cohort of patients with VACTERL defects at our clinical center. Our finding calls attention to bladder dysfunction as an additional VACTERL phenotypic component. The prevalence of bladder dysfunction is greatest in those with genital anomalies, anorectal malformations, sacral dysplasia, renal anomalies, and TSC. We propose that patients with two or more VACTERL malformations be monitored for symptoms of bladder dysfunction if one or more of the identified risk factors are present until the achievement of urinary continence.

Bilateral Vertebral Artery Fenestration in a Case of Craniovertebral Junction Neurenteric Cyst: Implications for Surgical Planning

Abstract Vertebral artery fenestration (VAF) is a type of anomaly of the vertebral artery in which a segment of the vessel divides into two separate channels that join together later in the course. Neurenteric cysts are rare, congenital lesions arising within the spinal canal usually in the cervical region. Vertebral artery anomalies if not considered during operative planning can lead to iatrogenic injury. We report a case of a 5-year-old boy who presented with a history of acute onset, non-traumatic spastic quadriparesis. Examination revealed the presence of cervical neurenteric cyst present ventrally at C1–C3 level. Further workup revealed the presence of bilateral VAF with the fenestrated part going along the inferior aspect of the arch of atlas bilaterally. Surgical excision of the lesion was done taking into consideration the anomalous course of vertebral artery. VAFs are classified according to their location as intracranial or extracranial and according to the segment of the vertebral artery from which they arise (V1–V4). Iatrogenic injury to the vertebral artery has been reported during both anterior and posterior approaches to the cervical spine. Due consideration should be given to anomalous course of vertebral artery while planning the surgical approach in craniovertebral junction.

Congenital Torticollis in a Child With Cervical Spine Deformity: A Case Report and Literature Review.

Congenital torticollis is an abnormal tilt of the neck in a newborn especially on the side of the pathology with the chin pointing toward the contralateral side. The most frequent cause is termed congenital muscular torticollis (CMT) which is a structural abnormality in the muscle of the neck called sternocleidomastoid muscle. There are also other causes of congenital torticollis that may arise such as anomalies of the cervical vertebrae, syndromic causes, and ocular defects. Diagnosing these other causes of congenital torticollis requires careful examination, cervical X-ray, CT scan, and MRI. The objective of this review is to create an awareness of the different types and causes of cervical spinal deformity. It also confirms that it is easy to misdiagnose these rarer causes of congenital torticollis as seen in a clinical vignette of a newborn who was managed for CMT for about one year with physical therapy and later turned out to have an associated hemivertebrae and fusion of the second and third cervical vertebrae. It is rare but it has the burden of huge financial and psychosocial impact.

Vertebral pattern and morphology is determined during embryonic segmentation.

The segmented nature of the adult vertebral column is based on segmentation of the paraxial mesoderm during early embryogenesis. Disruptions to embryonic segmentation, whether caused by genetic lesions or environmental stress, result in adult vertebral pathologies. However, the mechanisms linking embryonic segmentation and the details of adult vertebral morphology are poorly understood. We induced border defects using two approaches in zebrafish: heat stress and misregulation of embryonic segmentation genes tbx6, mesp-ba, and ripply1. We assayed vertebral length, regularity, and polarity using microscopic and radiological imaging. In population studies, we find a correlation between specific embryonic border defects and specific vertebral defects, and within individual fish, we trace specific adult vertebral defects to specific embryonic border defects. Our data reveal that transient disruptions of embryonic segment border formation led to significant vertebral anomalies that persist through adulthood. The spacing of embryonic borders controls the length of the vertebra. The positions of embryonic borders control the positions of ribs and arches. Embryonic borders underlie fusions and divisions between adjacent spines and ribs. These data suggest that segment borders have a dominant role in vertebral development.

Ear anomalies and hearing loss in patients with VACTERL association and the effect of maternal diabetes.

VACTERL association is typically defined as the presence of three components among these birth defects: vertebral anomalies, anal atresia, cardiac anomalies, esophageal atresia/tracheoesophageal fistula (EA/TEF), renal anomalies, and limb defects. There is increasing recognition that VACTERL and other recurrent constellations of embryonic development often overlap clinically and might share pathogenesis. We conducted a comprehensive chart review of a large patient population with VACTERL association from two tertiary care centers in California. We included patients with incomplete VACTERL expression, which we denoted as "partial VACTERL" (pVACTERL). We assessed the occurrence of craniofacial (CF) findings in these two groups and the combined cohort. We collected data on potential risk factors and demographic information such as sex, Hispanic ancestry, pregnancy complications, and maternal age. The study included 409 participants, of whom 263 had VACTERL and 146 pVACTERL. CF abnormalities were found in 17.3% of VACTERL patients and 9.4% of pVACTERL patients. In the VACTERL group, ear anomalies were found in 10.2%, microtia in 5.9%, hearing loss (HL) in 13.90%, and orofacial clefts in 3.1%. In the pVACTERL group, ear anomalies were found in 7.2%, microtia in 5.0%, HL in 9.3%, and orofacial cleft in 2.2%. Maternal diabetes significantly increased the risk for HL in VACTERL (odds ratio [OR]: 3.71, 95% confidence interval [CI]: 1.5-7.3) and pVACTERL patients (OR: 6.7, 95% CI: 1.70-23.4). Poorly controlled maternal diabetes significantly increased the risk for all the outcomes in VACTERL patients including CF anomalies (OR: 4.2, 95% CI: 1.9-9.6), ear anomalies (OR: 4.7, 95% CI: 1.8-11.8), microtia (OR: 5.4, 95% CI: 1.7-16.6), and HL (OR: 8.1, 95% CI: 3.4-19.4). Twin status was significantly associated with the occurrence of microtia (p = 0.038) in VACTERL patients. Occurrence of CF features, particularly ear anomalies, microtia, and HL, might be considered as part of phenotypic diversity of VACTERL association. Diabetes and twinning might appear to play a role in increasing the risk for this phenotype in VACTERL association.

Posterior L5 Transversectomy and Decompression for Far-out Syndrome caused by Lumbosacral Transitional Vertebra: A Case Report

Far-out syndrome is an unusual type of Bertolotti’s syndrome refers to L5 nerve root compressed by osteophyte in the extraforaminal zone, which leads to radical pain of the leg by radiculopathy. Conservative treatment is generally ineffective and requires operative decompression. We present the case of a 19-years-old patient complained of pain in the right lumbosacral and lower leg, failed for 2 months of conservative treatment. The patient was confirmed as far-out syndrome by imaging examinations showed the right L5 nerve root compressed by osteophytes from pseud arthrosis between the L5 transverse process and sacral ala. The Visual analog scale (VAS) pain score was 6 and the Oswestry disability index (ODI) was 53.33%. Then the osteophytes and pseudarthrosis were surgical removed and the L5 nerve root was decompressed through a posterior approach. The patient’s symptoms were significantly relieved after surgery immediately. The VAS score was 1 and ODI was 15.56% at 1-month postoperatively. At 1-year follow up, the VAS pain score was 1 and ODI was 11.11% and complete military trainings was resumed.

Prevalence of Transitional Vertebrae in Etiopathogenesis of Low Back Ache among South Indian Population: A Cross-sectional Study

Prevalence of Transitional Vertebrae in Etiopathogenesis of Low Back Ache among South Indian Population: A Cross-sectional Study

The Thoracic Inlet Length as a Reference Point to Radiographically Assess Cardiac Enlargement in Dogs with Myxomatous Mitral Valve Disease.

The diagnostic value of the vertebral heart size (VHS) in dogs with mitral valve degeneration (MVD) is compromised when middle thoracic vertebral anomalies are present. The objective of this study was to assess the use of the thoracic inlet heart score (TIHS) to identify left heart enlargement (LHE) secondary to MVD. The cardiac silhouette of 50 clinically healthy dogs and 106 MVD dogs in different stages was assessed on a right lateral chest radiograph. The TIHS and VHS value were calculated for each patient and compared. The TIHS was significantly different between the control dogs and the dogs with MMVD, increasing with disease stage, control 2.91 ± 0.23, Stage B1 2.98 ± 0.36, B2 3.25 ± 0.34, and C 3.53 ± 0.36, p < 0.05. A THIS ≥3.3 showed 69% sensitivity and 81% specificity to identify LHE. The TIHS showed moderate correlation with the VHS, LA/Ao, and LVIDDN 0.59, 0.42, and 0.62, respectively. The intraobserver and interobserver agreement were almost perfect, 0.96, and substantial, 0.73. The TIHS method can be used to identify LHE secondary to MMVD on dogs' thoracic radiographs.

The effect of lumbosacral transitional vertebra on lumbar spine degeneration and spondylolisthesis among patients with low back pain.

To examine the impact of lumbosacral transitional vertebra (LSTV) on lumbar spine degeneration, disc protrusion, and spondylolisthesis among patients with low back pain. The records of the patients who had undergone anterioposterior lumbar radiographs and lumbar magnetic resonance imaging (MRI) for low back pain between November 2014 and September 2021 were extracted retrospectively and assessed for eligibility. Of the remaining patients, those with LSTV were assigned as "case group." Age- and sex-matched patients without LSTV were assigned as "control group." On digitalized lumbar MRIs, Modic degeneration (type I-III) and Pfirrman's disc degeneration (grade I-V) immediately cephalad to the transitional level were evaluated; intervertebral disc height (mm), disc protrusion (mm), and percentage of vertebral slippage (%) were measured. Of the 501 patients with low back pain, 128 ineligible patients were excluded; 113 patients with LSTV and 117 age- and sex-matched controls were included in the study. LSTV group revealed decreased intervertebral disc height, increased vertebral endplate degeneration, and slippage, as well as increased disc degeneration and protrusion when compared with controls (p < 0.001). Patients with type III LSTV had greater disc protrusion and higher percentage of slippage compared to those with type I LSTV (p = 0.008 and p = 0.009, respectively). Vertebral endplate degeneration, disc height, and disc degeneration did not differ across categories of LSTV type. Lumbosacral transitional vertebra malformation is related to decreased intervertebral disc height, increased disc degeneration, vertebral endplate degeneration, disc protrusion, and slippage above the level of transition. Patients with type III LSTV revealed the highest percentage of slippage and disc protrusion.

BUU-LSPINE: A Thai Open Lumbar Spine Dataset for Spondylolisthesis Detection

(1) Background: Spondylolisthesis, a common disease among older individuals, involves the displacement of vertebrae. The condition may gradually manifest with age, allowing for potential prevention by the research of predictive algorithms. However, one key issue that hinders research in spondylolisthesis prediction algorithms is the need for publicly available spondylolisthesis datasets. (2) Purpose: This paper introduces BUU-LSPINE, a new dataset for the lumbar spine. It includes 3600 patients’ plain film images annotated with vertebral position, spondylolisthesis diagnosis, and lumbosacral transitional vertebrae (LSTV) ground truth. (4) Methods: We established an annotation pipeline to create the BUU-SPINE dataset and evaluated it in three experiments as follows: (1) lumbar vertebrae detection, (2) vertebral corner points extraction, and (3) spondylolisthesis prediction. (5) Results: Lumbar vertebrae detection achieved the highest precision rates of 81.93% on the AP view and 83.45% on the LA view using YOLOv5; vertebral corner point extraction achieved the lowest average error distance of 4.63 mm on the AP view using ResNet152V2 and 4.91 mm on the LA view using DenseNet201. Spondylolisthesis prediction reached the highest accuracy of 95.14% on the AP view and 92.26% on the LA view of a testing set using Support Vector Machine (SVM). (6) Discussions: The results of the three experiments highlight the potential of BUU-LSPINE in developing and evaluating algorithms for lumbar vertebrae detection and spondylolisthesis prediction. These steps are crucial in advancing the creation of a clinical decision support system (CDSS). Additionally, the findings demonstrate the impact of Lumbosacral transitional vertebrae (LSTV) conditions on lumbar detection algorithms.

Transitional lumbosacral vertebrae

Transitional lumbosacral vertebrae in the form of SI lumbarization and LV sacralization are classified as spinal anomalies. In the domestic medical literature, there are few publications devoted to these pathological conditions. In the course of a study of the available literature on the problem of transitional lumbosacral vertebrae, it was found that the frequency of cases of transitional lumbosacral vertebrae diagnosis ranges from 4 to 30% of clinical cases. The share of patients with lumbar vertebrae accounts for an average of 40% of cases, the share of patients with sacralization of the vertebrae is 60% of clinical observations. Mutations in the Hox gene are considered to be the trigger for the development of pathology, and pain is usually the leading clinical symptom. Plain radiography, computed tomography and magnetic resonance imaging are used to diagnose the pathology. Radiation imaging of the entire spine is required to eliminate errors in vertebrae counting. The type of pathology is determined using various classifications. As conservative therapeutic agents, drug blockades applying anesthetics and hormonal drugs are used. The arsenal of surgical interventions includes resection of the enlarged transverse process of the supracacral vertebra, decompression of stenotic intervertebral foramina, impulsive radiofrequency ablation, and posterior fusion. Measures for the prevention of pathology are not currently developed.

Vertebrae localization, segmentation and identification using a graph optimization and an anatomic consistency cycle.

Vertebrae localization, segmentation and identification in CT images is key to numerous clinical applications. While deep learning strategies have brought to this field significant improvements over recent years, transitional and pathological vertebrae are still plaguing most existing approaches as a consequence of their poor representation in training datasets. Alternatively, proposed non-learning based methods take benefit of prior knowledge to handle such particular cases. In this work we propose to combine both strategies. To this purpose we introduce an iterative cycle in which individual vertebrae are recurrently localized, segmented and identified using deep-networks, while anatomic consistency is enforced using statistical priors. In this strategy, the transitional vertebrae identification is handled by encoding their configurations in a graphical model that aggregates local deep-network predictions into an anatomically consistent final result. Our approach achieves the state-of-the-art results on the VerSe20 challenge benchmark, and outperforms all methods on transitional vertebrae as well as the generalization to the VerSe19 challenge benchmark. Furthermore, our method can detect and report inconsistent spine regions that do not satisfy the anatomic consistency priors. Our code and model are openly available for research purposes.1.

Determining the Accuracy of MRI in Evaluation of Infective Vertebral Lesions

Introduction:MRI is highly accurate in identifying vertebral anomalies by detecting even the smallest changes in water and fat components, making it the preferred method for assessing infectious lesions in the vertebral column. Clinical observations and different imaging properties can help with early diagnosis and treatment. Vertebral endplate destruction, changes in the signal intensity of intervertebral disc and bone marrow, and involvement of the soft tissues surrounding the vertebrae are typical MRI findings of infectious vertebral lesions.Methods:To determine the diagnostic accuracy of MRI in patients suspected of having infective vertebral lesions, a cross-sectional study was conducted involving 52 individuals. The study compared the validity of MRI diagnosis with the diagnosis obtained through CT-guided fine needle aspiration cytology for infective vertebral lesions.Results:By comparing the MRI diagnoses with those of fine needle aspiration cytological diagnosis of vertebral lesions, the sensitivity, specificity, positive and negative predictive values (PPVs and NPVs), and ultimately diagnostic accuracy of MRI, were computed. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MRI diagnosis for infective vertebral lesions were 95.6%, 71.4%,95.6%, and 71.4%, respectively and 92.3% of diagnoses were made correctly overall.Conclusions:The finding of this study suggested that MRI should be considered to be the imaging modality of choice for patients with suspected infective vertebral lesions.

Neurodevelopmental outcomes in individuals with VACTERL association. A population-based cohort study.

Studies on neurodevelopmental outcomes in individuals with congenital anomalies who undergo neonatal surgery are scarce and have reported contradictory findings based on small study groups. The congenital condition VACTERL association includes at least three malformations: vertebral anomalies, anorectal malformations, cardiac defects, tracheoesophageal fistula with or without esophageal atresia, renal anomalies and limb deformities. Most of these patients undergo surgery during their first days of life. Neurodevelopmental disorders include a broad group of disabilities involving some form of disruption to brain development. Attention deficit hyperactivity disorder (ADHD), autism spectrum disorders (ASD) and intellectual disability (ID) are diagnoses included in this group. The aim of the study was to investigate the risk of ADHD, ASD and ID in a cohort of individuals with VACTERL association. Data was obtained from four Swedish national health registers and analyzed using the Cox proportional hazards model. Patients born 1973-2018 in Sweden with the diagnosis of VACTERL association were included in the study. For each case five healthy controls matched for sex, gestational age at birth, birth year and birth county were obtained. The study included 136 individuals with VACTERL association and 680 controls. Individuals with VACTERL had significantly higher risk of ADHD, ASD and ID than the controls; 2.25 (95% CI, 1.03-4.91), 5.15 (95% CI, 1.93-13.72) and 8.13 (95% CI, 2.66-24.87) times respectively. A higher risk of ADHD, ASD and ID was found among individuals with VACTERL association compared to controls. These results are of importance to caregivers and to professionals participating in follow ups of these patients in providing early diagnosis and support, aiming to optimize the quality of life of these patients.

Spina Bifida Sacralis Occulta from Ancient Greek Sicily (Pozzanghera Necropolis, Leontinoi, 6th–4th Century BC): Anatomical, Anthropological and Ethnomedical Considerations on the Insular Presentation of this Congenital Anomaly

In this article a case of spina bifida sacralis occulta (SBSO) from the Pozzanghera necropolis of the ancient Greek colony of Leontinoi (Sicily) and archaeologically dated to the 6th–4th century BC is morphologically analysed and discussed. An ethnomedical excursus on the knowledge and impact of this condition in Sicilian history is offered. Although SBO is one of the most frequent congenital anomalies in the global palaeopathological record, a comprehensive literature search did not yield results for the history of Sicily before Christ, hence this case enriches existing knowledge on the historical presentation of this vertebral congenital anomaly in this region.

Lumbosacral endplate contour defect is frequently observed concurrent with other lumbosacral abnormalities on spinal CT of French Bulldogs.

Lumbosacral osteochondrosis has been previously described in large breed dogs with variable clinical signs. Its CT features are a contour defect at the dorsal aspect of either vertebral endplate, commonly with an adjacent fragment. Descriptions of this condition have not been previously published in an increasingly popular breed, French Bulldogs. Aims of this retrospective, descriptive, single center study were to evaluate CT lumbosacral abnormalities and the frequency of lumbosacral endplate contour defect in a large sample of French Bulldogs. The presence and location of lumbosacral endplate contour defect and the presence of a concurrent osseous fragment were recorded. Other abnormal CT findings such as L7-S1 disc herniation, cauda equina nerve roots compression or thickening, disc mineralization, endplate sclerosis, spondylosis deformans, S1 articular processes hypertrophy, transitional vertebrae, hemivertebrae, spina bifida, and block vertebrae were recorded. Lumbosacral CT abnormalities were present in 91.8% of dogs (168/183). The most common abnormality was an L7-S1 dorsal disc herniation (77.4%, 130/168). Among dogs with lumbosacral abnormalities, the frequency of a lumbosacral endplate contour defect was 47% (79/168). It mostly involved L7 (78.5%, 62/79) at its dorsolateral aspect (61.3%, 38/62). A mineralized fragment was identified in 62% of the defects (49/79). Endplate contour defects were most frequently seen with a concurrent disc herniation (93.7%, 74/79) causing nerve root compression in 63.3% (50/79) and with sclerosis (65.8%, 52/79). There was no definitive evidence of a relationship with clinical presentation in this sample of French Bulldogs; therefore, this finding should be interpreted with caution. The etiology remains unclear.

The influence of lumbo-sacral transitional vertebrae in developmental dysplasia of the hip: a matched pair analysis

Lumbo-sacral transitional vertebrae (LSTV) are the most common congenital alteration of the lumbo-sacral junction and known to significantly influence pelvic anatomy. However, the influence of LSTV on dysplasia of the hip (DDH) and the surgical treatment by periacetabular osteotomy (PAO) remains unknown. We retrospectively examined standardized standing anterior–posterior pelvic radiographs of 170 patients in 185 PAO procedures. Radiographs were examined for LSTV, lateral-central-edge-angle (LCEA), Tönnis-angle (TA), femoral-head-extrusion index (FHEI), and anterior-wall-index (AWI) and posterior-wall-index (PWI). Patients with LSTV were compared to an age- and sex-matched control group. Patient-reported outcome measurements (PROMs) were evaluated pre- and in the mean 63.0 months (range 47–81 months) postoperatively. 43 patients (25.3%) had LSTV. Patients with LSTV had significantly greater PWI (p = 0.025) compared to the matched control group. No significant differences were seen in AWI (p = 0.374), LCEA (p = 0.664), TA (p = 0.667), and FHEI (p = 0.886). Between the two groups, no significant differences were detected in pre- or postoperative PROMs. Due to the increased dorsal femoral head coverage in patients with LSTV and DDH compared to patients with sole DDH, a more pronounced ventral tilting might be performed in those patients with prominent posterior wall sign to avoid anterior undercoverage, which is a significant predictor for premature conversion to hip arthroplasty after PAO. However, anterior overcoverage or acetabular retroversion must be avoided due to the risk of femoroacetabular impingement. Patients with LSTV reported similar functional outcomes and activity after PAO as the control group. Therefore, even for patients with concomitant LSTV, which are frequent with one-fourth in our cohort, PAO is an efficient treatment option to improve clinical symptoms caused by DDH.
