ABSTRACT

The proximal medial column of the humerus is a continuous cortical region in the inner and lower part of the humerus head, which has attracted more and more attention in clinical and scientific research since it was proposed. It has been shown to increase the stability of internal fixation, maintain the height of the humeral head to prevent varus, and reduce the risk of screw penetration. Biomechanical studies have also shown that the medial column has an outstanding performance in increasing the stiffness, torsion resistance, and shear resistance of the locking plate. Although it has many benefits, there is no unified definition of its concept and specific region, and the existing classification does not include the medial column, therefore more researches are required to provide supporting information. The methods of medial column reconstruction mainly include locking plate combined with talus screw, locking plate combined with bone grafting, internal and external double plate combined support, locking plate combined with bone cement, and humeral cage. These methods have their own characteristics, however they will increase the cost of surgery and bring new complications. How to determine the best way of reconstruction is one of the focuses of future research. In this review, the concept of the proximal medial humerus column, the role of maintaining internal fixation, the role of biomechanics and the reconstruction methods are reviewed.

ABSTRACT

Abstract Objective To analyze long-term functional and radiographic results of partial shoulder replacement for humeral head osteonecrosis. Methods Retrospective review of thirteen cases, with a mean postoperative follow-up of 17 years (range 10 to 26 years). The findings from the last follow-up were compared to those in which the patients had one year of postoperative follow-up. Functional assessment consisted of shoulder movement measurements and application of the University of California, Los Angeles (UCLA) shoulder score. All patients underwent radiographic examination to measure glenoid erosion, proximal humeral migration and lateral glenohumeral dislocation. Results Glenoid erosion increased over time significantly (p < 0.05). Paradoxically, all active shoulder movements also improved (p < 0.05), while UCLA scores remained the same. Radiographic deterioration was not correlated with clinical function. We had an 84.7% survival rate for arthroplasties after a mean time of 16 years. Conclusions Early functional outcomes were maintained in the long run and do not correlate with radiographic deterioration (increased erosion of the glenoid).


Resumo Objetivo Analisar os resultados funcionais e radiográficos de longo prazo da artroplastia parcial do ombro para estosteonecrose da cabeça do úmero. Métodos Revisão retrospectiva de 13 casos, com seguimento pós-operatório médio de 17 anos (variação de 10 a 26 anos). Os achados do último seguimento foram comparados àqueles em que os pacientes tinham com 1 ano de acompanhamento pós-operatório. A avaliação funcional consistiu em medidas do movimento do ombro e aplicação do escore do ombro da Universidade da Califórnia, Los Angeles (UCLA). Todos os pacientes foram submetidos a exame radiografico para medir a erosão glenoidal, a migração umeral proximal, e o deslocamento glenoumeral lateral. Resultados A erosão da glenoide aumentou com o tempo significativamente (p < 0,05). Paradoxalmente, todos os movimentos ativos do ombro também melhoraram (p < 0,05), enquanto os escores da UCLA permaneceram os mesmos. A deterioração radiográfica não teve correlação com a função clínica. Tivemos uma taxa de sobrevida de 84,7% das artroplastias após tempo médio de 16 anos. Conclusões Os resultados funcionais precoces mantiveram-se a longo prazo e não se correlacionem com a deterioração radiográfica (aumento da erosão glenoidal).

ABSTRACT

The incidence of posterior instability of shoulder joint was significantly lower than that of anterior instability, but the clinical diagnosis and treatment was difficult, and the misdiagnosis and missed diagnosis rate were high. Its etiology, clinical manifestation and treatment strategy are totally different from the anterior instability. Therefore, the deep understanding of the anatomical structure around the shoulder joint, the mastery of the examination method, and the classification of the shoulder instability based on the anatomy and injury mode are of great importance to improve the accuracy of diagnosis. CT three-dimensional reconstruction is helpful to evaluate the defect of humeral head and glenoid bone, and MRA is helpful for the accurate diagnosis of posterior glenoid lip and joint capsule. The treatment was divided into conservative treatment and surgical treatment. Conservative treatment is recommended for muscular instability. Surgical treatment is recommended for traumatic and dysplastic instability. Different operative methods should be performed according to the injury of glenoid side or humeral head side. According to the condition of bone defect, soft tissue operation, bone grafting or osteotomy were performed to reconstruct the posterior stable structure of the glenoid injury; according to the area of the anterior bone defect, bone grafting or subscapular muscle packing were performed to the head of humerus defect. The former has the advantages of short learning curve and firm fixation, while the latter has the advantages of minimally invasive operation and the ability to observe the lesions from multiple angles and accurately control the location of bone masses. This paper summarizes the above problems.

ABSTRACT

Proximal humerus fracture is one of the common shoulder fractures. With the increase in incidence, the proportion of surgical intervention is increasing. This paper explores the traditional and new treatment methods for proximal humerus fracture. Locking plate technology is the most commonly used method in the clinic, but its complication rate of intra-articular screw penetration and reoperation is too high.Fibular strut allografts can provide adequate support, but it is a significant trauma surgery and has a high incidence of potential disruption to necessary vascular.Arthroplasty is one of the treatments for complex proximal humerus fractures, but it has a long learning curve and high cost.In recent years, the proximal humerus cage's intervention model has emerged, which has the inherent advantagesof a three dimensional structure, which can provide adequate load bearing support for the humeral head and provide flexible screw placement Angle. The cage offers a new technical option to reduce postoperative complications and improve patients' rehabilitation safety. A comprehensive grasp of the treatments of proximal humerus fracture and rational choice of intervention measures will benefit patients.

ABSTRACT

OBJECTIVE@#To evaluate the association between rotator cuff tear and the proximal migration of humeral head.@*METHODS@#In this research, we retrospectively selected 30 patients with unilateral rotator cuff tear in Peking University People's Hospital from September 2015 to May 2016, who received magnetic resonance imaging (MRI) and X-ray of the painful shoulder before enrollment in this study, the duration between the two examinations was no longer than 1 week, and also there was no past history of surgery in the selected shoulders. There was no other exclusion criteria. Upward migration index (UMI) was the ratio between the distance of humeral head center to the lower surface of acromion, and the radius of humeral head circle, which could help to minimize the effect of anatomy difference and imaging magnification, compared with the traditional acromiohumeral distance (AHD). Then we introduced this index to stratify the selected 30 patients into 3 groups, and each group contained 10 patients, UMI of group 1 was >1 and ≤1.2, UMI of group 2 was >1.2 and ≤1.4, UMI of group 3 was >1.4. As the supraspinatus was most commonly affected by pathological change among the four rotator cuff tendons, we took it as the research object. Then we used the Spearman correlation analysis to evaluate the relationship between UMI and fatty degeneration, rotator cuff tear size and the thickness of ruptured supraspinatus tendon from X-ray and MRI.@*RESULTS@#In the A-P view, the average UMI was 1.33 (1.02-1.51, SD: ±0.22). UMI and the tear size had a significant negative correlation (R=-0.584, P<0.01), and also there was a negative correlation between the fatty degeneration of the supraspinatus (R=-0.312, P=0.033). However, there was no correlation between UMI and the thickness of ruptured supraspinatus (R=0.127, P=0.071).@*CONCLUSION@#UMI is related with the fatty degeneration of supraspinatus and the tear size. The reduction of UMI is a predictable and reliable mark of rotator cuff tear and degeneration in clinic. Physicians can use physical examination and X-ray first when facing the patients with shoulder pain, which is convenient and helpful for evaluating rotator cuff tears.

ABSTRACT

PURPOSE: This study analyzed the features of humeral head decentralization in large to massive rotator cuff tears with a shoulder dislocation in the elderly. Moreover, shoulder instability and treatment were reviewed. MATERIALS AND METHODS: From May 2005 to February 2017, Group A containing 45 cases (45 patients) over 65 years old accompanied by a large or massive rotator cuff tear with a shoulder dislocation and Group B containing 45 cases (45 patients) without a shoulder dislocation were enrolled. The mean ages in Groups A and B were 73.2 and 72.1 years old, and the mean follow-up periods were 30.7 and 31.3 months, respectively. Twenty-one cases (46.7%) in Group A underwent rotator cuff repair, and 8 cases (17.8%) underwent concomitant rotator cuff repair with Bankart repair. Sixteen cases (35.6%) underwent reverse total shoulder arthroplasty for cuff tear arthropathy. 45 cases (100%) in Group B underwent rotator cuff repair. The off-the center and head elevation were measured in the preoperative magnetic resonance imaging (MRI) of Groups A and B. The preoperative and postoperative visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score in Groups A and B were compared. RESULTS: In Groups A and B, the mean off-the centers were posterior 7.41 mm and posterior 2.02 mm (p=0.03), and the mean head elevations were superior 6.66 mm and superior 2.44 mm (p=0.02), respectively. The mean ASES scores of Groups A and B were 32.8 and 33.4 before surgery, and 77.1 (p=0.02) and 78.1 (p=0.02) after surgery (p=0.18), respectively. The mean UCLA scores of Groups A and B were 13.1 and 12.8 before surgery, and 28.9 (p=0.02) and 29.5 (p=0.01) after surgery (p=0.15), respectively. CONCLUSION: Patients over 65 years old with a shoulder dislocation in large to massive rotator cuff tears had higher off-the center and head elevation on the preoperative MRI than those without a shoulder dislocation. This measurement can help predict preceding shoulder instability. Early rotator cuff repairs should be performed and other treatments, such as Bankart repair and reverse total shoulder arthroplasty, should also be considered.

ABSTRACT

Avascular necrosis (AVN) is defined as the cellular death of bone and bone marrow components due to the loss of blood supply, and associated with post-traumatic or non-traumatic events. AVN usually involves the epiphysis of a long bone, such as the femoral and humeral heads, which are susceptible to osteonecrosis. Many studies have been conducted but they were restricted to investigations of femoral head avascular necrosis. The presence of osteonecrosis in the proximal femur may impair biological fixation after total hip arthroplasty. We report a 56-year-old male patient with avascular necrosis located not only at the femoral head, but also in the entire femur, including the medullary cavity, who underwent total hip arthroplasty 2 years earlier along with a review of the relevant literature.

ABSTRACT

Proximal humerus fracture can be defined as a fracture that occurs in the surgical neck or proximal part of the humerus. Despite the appropriate treatment, however, various complications and sequelae can occur, and the treatment is quite difficult often requiring surgical treatment, such as a shoulder replacement. The classification of sequelae after a proximal humerus fracture is most commonly used by Boileau and can be divided into two categories and four types. Category I is an intracapsular impacted fracture that is not accompanied by important distortions between the tuberosities and humeral head. An anatomic prosthesis can be used without greater tuberosity osteotomy. In category I, there are type 1 with cephalic collapse or necrosis with minimal tuberosity malunion and type 2 related to locked dislocation or fracture-dislocation. Category II is an extracapsular dis-impacted fracture with gross distortion between the tuberosities and the humeral head. To perform an anatomic prosthesis, a tuberosity osteotomy should be performed. In category II, there are type 3 with nonunion of the surgical neck and type 4 with severe tuberosity malunion. In type 1, non-constrained arthroplasty (NCA) without a tuberosity osteotomy should be considered as a treatment. On the other hand, reverse shoulder arthroplasty (RSA) should be considered if types 1C or 1D accompanied by valgus or varus deformity or severe fatty degeneration of the rotator cuff. In general, the results are satisfactory when NCA is performed in type 2 sequelae. On the other hand, RSA can be considered as an option when there is no bony defect of the glenoid and a defect of the rotator cuff is accompanied. In type 3, it would be effective to perform internal fixation with a bone wedge graft rather than shoulder replacement arthroplasty. Recent reports on the results of RSA are also increasing. On the other hand, recent reports suggest that good results are obtained with RSA in type 3. In type 4, RSA should be considered as a first option.

ABSTRACT

OBJECTIVE@#To observe the effect of anti-osteoporosis drugs on the curative effect of femoral head replacement in the elderly patients with proximal humerus fracture.@*METHODS@#From November 2012 to June 2016, 38 patients with proximal humeral fractures received humeral head replacement were divided into the treatment group and the control group according to whether the anti-osteoporosis drugs were used after the operation. The treatment group included 19 cases, of which 11 cases were three part fractures, 18 cases were four part fractures, and bone density was(0.58±0.14) g/cm²; the control group involved 19 cases, of which 10 cases were the three part fractures, 9 cases were four part fractures, and bone density was(0.58±0.11) g/cm². Periprosthetic bone mineral density(BMD) was measured at 4, 8, 12, 24 and 48 weeks after operation, and visual analogue scale(VAS) was used to evaluate the pain and Neer score was used to evaluate the function of the shoulder joint.@*RESULTS@#The incisions of all patients were healed with grade A and no complications occurred. Thirty-five patients were followed up for 1 year. The bone density around the prosthesis of treatment group was higher than that of control group, the difference was statistically significant(0.05). The total score and functional score of Neer in the treatment group were better than those in the control group, the difference was statistically significant(0.05). According to the Neer score, the results of treatment group was excellent in 10 cases, good in 5 cases, fair in 3 cases;in the control group, 3 cases were excellent, 9 cases were good, and 5 cases were fair;the difference between the two groups was statistically significant(<0.05).@*CONCLUSIONS@#Artificial humeral head replacement combined with anti-osteoporosis drugs in the treatment of proximal humeral fractures in elderly patients can effectively improve the bone density around the prosthesis and restore shoulder function. The early clinical effect is satisfactory.

ABSTRACT

Milwaukee shoulder syndrome (MSS) is a rare disease in which joints are destroyed and occurs mainly in elderly women. We describe rapidly progressive MSS with complete destruction of the shoulder joint within 2 months. An 80-year-old woman visited the outpatient clinic with shoulder pain for 2 weeks. rotator cuff tear arthropathy was diagnosed, and nonsteroidal anti-inflammatory drugs were prescribed. Two months later, her shoulder pain worsened without trauma. Shoulder swelling and tenderness, and arm lifting inability were observed. Complete humeral head disruption was observed by radiography. We diagnosed MSS based on the presence of serohematic and noninflammatory joint effusion, periarticular calcific deposits, and rapid joint destruction, and initiated conservative treatment. When initially treating elderly patients with shoulder arthropathy, it is advisable to perform short-term follow-up and to consider the possibility of crystal-induced arthropathy.

ABSTRACT

PURPOSE: The aim of this study is to evaluate the T2 value of the articular cartilage of the glenohumeral joint in rotator cuff disease displayed on 3.0T MRI and to apply it in clinical practice. MATERIALS AND METHODS: This study involved sixty-two patients who underwent shoulder MRI containing T2 mapping. The mean T2 value was measured by placing a free hand ROI over the glenoid or humeral cartilage from the bone-cartilage interface to the articular surface on three consecutive, oblique coronal images. The drawn ROI was subsequently divided into superior and inferior segments. The assessed mean T2 values of the articular cartilage of the glenohumeral joint were compared and evaluated based on the degree of rotator cuff tear, the degree of fatty atrophy of the rotator cuff, and the acromiohumeral distance. RESULTS: ICC values between two readers indicated moderate or good reproducibility. The mean T2 value for the articular cartilage of the glenoid and humeral head cartilage failed to show any significant difference based on the degree of rotator cuff tear. However, the mean T2 values of articular cartilage, based on fatty atrophy, tended to be higher in fatty atrophy 3 or fatty atrophy 4 groups while some sub-regions displayed significantly higher mean T2 values. There was no correlation between the acromiohumeral distance and the mean T2 values of the articular cartilage of the glenoid and humeral head. CONCLUSION: T2 mapping of the glenohumeral joint failed to show any significant difference in quantitative analysis of the degenerative change of the articular cartilage based on the degree of rotator cuff tear. However, it also offers quantitative information on the degenerative change of cartilage of the glenohumeral joint in patients with rotator cuff tear and severe fatty atrophy of the rotator cuff.

ABSTRACT

BACKGROUND: Posterior decentering is not an uncommon finding on rotator cuff tear patients' shoulder magnetic resonance imaging. No previous study has reported on the relationship between posterior decentering and rotator cuff tear. METHODS: We assessed patients' rotator cuff tear humeral head positions based on humeral–scapular alignment (HSA). Subjects were classified into centering and decentering groups based on a 2 mm HSA value, respectively. Differences in rotator cuff tear size, degree of tear, and fatty degeneration between the two groups were evaluated. RESULTS: One hundred seventy-five patients (80 males, 95 females; mean age: 59.7 ± 6.5 years old) were selected as subjects (case-control study; level of evidence: 3). Tear size, degree of subscapularis tendon tear, and fatty degeneration of the supraspinatus, infraspinatus, and subscapularis muscles were significantly different between the two groups (p<0.001, p<0.001, p<0.001). CONCLUSIONS: The occurrence of decentering was related to rotator cuff tear size, degree of subscapularis tendon tear, and fatty degeneration of the rotator cuff muscles.

ABSTRACT

Irreducible dislocation of the elbow is an uncommon event. We present the case of a posterolateral elbow dislocation after a fall injury in a 67-year-old woman. A closed reduction performed in the emergency department was unsuccessful since the limited passive range of motion resulted in difficulty to perform longitudinal traction and flexion. Computed tomography images showed that the posterolateral aspect of the capitellum was impacted by the tip of the coronoid process, thus appearing similar to the Hill-Sachs lesion in the humeral head. Subsequent open reduction of the elbow revealed the dislocation to be irreducible since the tip of the coronoid process had wedged into a triangular Hill-Sachs-like lesion in the capitellum. The joint was reduced by providing distal traction on the forearm, and main fragments were disengaged using digital pressure. At the 3-month follow-up, the patient reported no dislocations, and had an acceptable range of motion. Thus, we propose that to avoid iatrogenic injury to the joint or other nearby structures, irreducible dislocations should not be subjected to repeated manipulation.

ABSTRACT

Ultrasound diathermy is widely used for the treatment of musculoskeletal disorders and other soft tissue injuries. Its use as a therapeutic modality is believed to be safe, with very few reported complications. Here, we report two patients who developed focal bone marrow abnormalities after receiving ultrasound diathermy. Both patients' magnetic resonance (MR) evaluations revealed linear subchondral bone lesions of the superolateral humeral head similar to those in osteonecrosis. The patients' symptoms subsequently improved, and available follow-up MR evaluation revealed near complete resolution of bone lesions. These findings suggest that ultrasound diathermy, and its interaction with bone tissue through thermal mechanisms, can cause focal bone marrow abnormalities. Furthermore, the bone marrow abnormalities seem to be transient, resolving upon cessation of ultrasound diathermy, therefore osteonecrosis should be differentiated from this temporal lesion.

ABSTRACT

A proximal humeral fracture is an osteoporotic fracture that often occurs in elderly women. Approximately 80% of all proximal humeral fractures are non-displaced fractures, which can be treated with conservative treatment to achieve stable union. The treatment plan for fractures involving displaced and comminuted fractures is controversial. Malunion, avascular necrosis of the humeral head, and shoulder stiffness due to conservative treatment can occur but the functional deterioration is low and the patient satisfaction is high. The indications for the conservative management of proximal humeral fractures include a non-displaced fracture and a 2-part fracture, low-functional demanded 3-part fracture, and operative-limited 4-part fracture. Recently, the surgical indications have expanded as technological advances in surgical fixation methods and functional needs of elderly patients are increasing. Current treatment policy decisions tend to be determined by the personal preference and expert opinion rather than by evidence-based decision-making.

ABSTRACT

OBJECTIVE: To correlate the acromiohumeral distance (AHD) using tomosynthesis and rotator cuff (RC) pathology and various anatomical indices and to assess the diagnostic reproducibility of tomosynthesis for the evaluation of subacromial impingement. MATERIALS AND METHODS: A retrospective review of 63 patients with clinically suspected subacromial impingement was conducted. Two musculoskeletal radiologists independently measured the following quantitative data: the AHD on plain radiographs and the AHD at three compartments (anterior, middle, and posterior) using tomosynthesis, computed tomography (CT) arthrography, or magnetic resonance (MR) arthrography. To investigate the association between the AHD and RC pathology and various anatomical indices, we reviewed the arthroscopic operation record as the referenced standard. RESULTS: The size of rotator cuff tear (RCT) in full-thickness tears displayed a significant inverse correlation with the middle and the posterior tomosynthetic AHDs (p < 0.05). The results of an ANOVA revealed that the middle tomosynthetic AHD retained a significant association with the type of RCT (p = 0.042), and the posterior tomosynthetic AHD retained significance for the size of RCT in a full-thickness tear (p = 0.024). The inter-modality correlation exhibited significant agreement especially among the plain radiography, tomosynthesis, and CT or MR arthrography (p < 0.05). The intraobserver and interobserver correlation coefficients (ICCs) displayed excellent agreement (ICC = 0.896–0.983). The humeral head diameter and glenoid height were significantly correlated with patient height and weight. CONCLUSION: Acromiohumeral distance measurement using tomosynthesis is reproducible compared with other modalities.

ABSTRACT

BACKGROUND: This study introduces a surgical technique with good clinical outcome useful in the treatment of osteoporotic displaced 3- or 4-part proximal humeral fractures. METHODS: From May 2014 to February 2016, 16 patients with displaced 3- or 4-part proximal humeral fractures were treated by application of a locking plate with an endosteal strut allograft via a deltoid splitting approach with a minimum follow-up of 12 months. The allograft was inserted through a fractured gap of the greater tuberosity to support the humeral head and then fixed by a locking plate with meticulous soft tissue dissection to protect the axillary nerve. Surgical outcomes were evaluated by the American Shoulder and Elbow Surgeons (ASES) and visual analogue scale (VAS) scores, radiological imaging, and clinical examination. Fixation failure on radiographs was defined as a >5° loss of neck shaft angle (NSA) compared to that on an immediate postoperative radiograph. Avascular necrosis (AVN) of the humeral head was also evaluated. RESULTS: In all cases, complete union was achieved. The ASES and VAS scores were improved to 85.4 ± 2.1 and 3.2 ± 1.3, respectively. Twelve patients (75.0%) had greater than a 5° change in NSA; the average NSA change was 3.8°. Five patients (31.3%) had unsatisfactory ranges of motion exhibiting a < 100° active forward flexion. No axillary nerve injuries or AVN were observed at the last follow-up. One patient was converted to reverse total arthroplasty due to severe pain and functional deficit. CONCLUSIONS: Minimally invasive fixation via a locking compression plate and an endosteal fibula strut allograft in Neer classification 3-or 4-part fractures with severe osteoporosis in elderly patients can achieve good clinical results.

ABSTRACT

Resumen: Introducción: La artropatía por desgarro masivo del manguito de los rotadores (ADMMR) condiciona un desplazamiento de la cabeza humeral acompañada de acetabularización del acromion y femoralización de la glenoides. El objetivo de este estudio fue conocer la prevalencia de la ADMMR en el Instituto Nacional de Rehabilitación (INR). Material y métodos: Se realizó un estudio de prevalencia que incluyó la revisión de 400 expedientes para identificar a 136 pacientes con lesión del manguito de los rotadores. Se integró un subgrupo para pacientes con lesión masiva del manguito de los rotadores (LMMR) y ADMMR. Se estudiaron variables y se estadificaron. Resultados: Se incluyeron 34 pacientes con LMMR (26 mujeres y 8 hombres) con una edad promedio de 60.1 ± 10.26 años. Se registró una prevalencia de 25% de LMMR en el grupo global con lesión del manguito de los rotadores. Asimismo, se buscó la prevalencia de ADMMR en el grupo global y en el subgrupo de lesiones masivas, siendo de 19 y 76%, respectivamente. Los pacientes con LMMR se estadificaron para conocer el grado de ADMMR mediante la clasificación de Seebauer, encontrando 32% con estadios 1a, 11% 1b, 32% 2a, 0% 2b y 23% no presentaban datos de ADMMR. Conclusión: La prevalencia de ADMMR en pacientes del servicio incluido con lesión del manguito de los rotadores y LMMR es mayor a la reportada en la literatura sajona.


Abstract: Introduction: Glenohumeral arthritis secondary to massive rotator cuff tear presents with a superior displacement and femoralization of the humeral head with coracoacromial arch acetabularization. The purpose of this study was to establish prevalence of rotator cuff tear artropathy (CTA) at our institution. Material and methods: Four hundred electronic records were reviewed from which we identified 136 patients with rotator cuff tears. A second group was composed with patients with massive cuff tears that were analized and staged by the Seebauer cuff tear arthropathy classification. Results: Thirty four patients with massive rotator cuff tears were identified, 8 male and 26 female (age 60.1 ± 10.26 years). Massive rotator cuff tear prevalence was 25%. CTA prevalence found in the rotator cuff group was 19 and 76% in the massive cuff tears group. Patients were staged according to the classification with 32% in stage 1a, 11% 1b, 32% 2a and 0% 2b. Conclusion: CTA prevalence in patients with rotator cuff tears and massive cuff tears is higher than the one reported in American population. We consider that a revision of the Seebauer classification to be appropriate to determine its reliability.
