Abnormal ossified structures around the hip joint and its clinical implications

Background: The hip joint is the body’s second largest weight-bearing joint forms a connection from the lower limb to the pelvic girdle. It is formed by an articulation between the pelvic acetabulum and the head of the femur. Ankylosis or fusion of the joint, ossification of the adjacent ligaments and calcific tendinitis of adjacent muscles can decrease the mobility of the joint. The study was undertaken to evaluate the incidence of abnormal ossified structures around the hip joint.Methods: This study was carried out on 228 dry human hip bones (right- 114 and left-114) and 228 dry human femur bones (right- 114 and left-114) irrespective of age and sex at Varun Arjun medical college-Banthra, UP, KMCT Medical College, Manassery-Calicut and Melaka Manipal Medical College-Manipal. All the hip and femur bones were macroscopically inspected for the abnormal ossified structures around the pelvic acetabulum and upper end of the femur. Photographs of the abnormal ossified structures were taken for proper documentation.Results: Very rare and unusual unilateral ossified and complete fused left hip joint was noted (0.43%). Unilateral ossified acetabular labrum with ossified transverse acetabular ligament was noted in seven right hip bones (3.07%). Unusual ossified fibrous capsule on the posterior aspect of neck of femur was noted in 4 left sided femur bones (1.75%). Unusual unilateral ossified deposits near the greater trochanter and intertrochanteric line of femur was noted in nine left sided femur bones (3.94%).Conclusions: Anatomical knowledge of ankylosis of hip joint, ossification of the ligaments and muscles tendons around the hip joint as found in the present study made this study unique such abnormal ossifications may be helpful for clinicians, radiologists and surgeons for differential diagnosis and can be implicated in the development of innovative treatments of hip joint and hip pains

Anatomical and congenital variations of human dry sternum bone: its embryogenesis and clinical implications

Background: The sternum is one of the skeleton parts with frequently detected variation in cross-sectional images or autopsy series. The anatomical or congenital variations of the sternum in the anterior chest wall may involve malignancies, injuries or severe traumas. The aim of the study was undertaken to evaluate the incidence of anatomical and congenital variations of human dry sternum bones.Methods: This study was carried out on 120 dry human sternum bones irrespective of age and sex at Varun Arjun medical college- Banthra, UP, KMCT Medical College, Manassery-Calicut and Melaka Manipal Medical College-Manipal. All the sternum bones were macroscopically inspected for the anatomical and congenital variations of human dry sternum bones. Photographs of the anatomical and congenital variations were taken for proper documentation.Results: Complete sternal foramina in the body of the sternum were noted in 9 bones (7.5%), with an average vertical diameter of 17mm and transverse diameter of 16mm (The highest vertical diameter of 19mm and transverse diameter of 17mm was noted); Incomplete sternal foramina in the body of the sternum were noted in 4 bones (3.3%);Complete sternal foramina in the xiphoid process of the sternum were noted in 7 bones (5.8%) with an average vertical diameter of 6mm and transverse diameter of 8mm; Unusual complete sternal foramina in the body and incomplete sternal foramina in the xiphoid process of the sternum were noted in 8 bones (6.6%); Very rare longer xiphoid process (7.3 cm) with complete sternal foramina was noted in 7 bone (5.8%); Unusual Longer xiphoid process with an average length of 6.7cm with sharp bifid ends was noted in 8 bones (6.6%).Conclusions: The knowledge of existence of anatomical variants and congenital foramina of sternum and xiphoid process found in our study is essential, especially for bone marrow sampling, radiology (X - ray, CT, MRI, and USG) reporting, pathology autopsy and forensic medicine post-mortem reporting and patoacupuncture practice to avoid complications during various surgical procedures

Unreported anomalous musculature of first pharyngeal arch: Its embryogenesis and clinical anatomy

Musculature of first pharyngeal arch play an important role in mastication, speech and swallowing thus a comprehensive knowledge of anatomical variations will be important for surgeons and Traumatologists which can increase the success of diagnostic evaluation and surgical approaches to the region. Accordingly, the purpose of this study was designed to evaluate the prevalence of anomalous musculature of first pharyngeal arch in the human cadavers. This study was carried out on 107 formalin embalmed human cadavers (male 62 and 45 female), and dissections were performed in accordance with the institutional ethical standards and Indian anatomy act. Out of 107 cadavers, in three cadavers the following rare unreported muscular variations of first pharyngeal arch were encountered in the present study: 1. Rare and unusual unilateral quadrilateral anomalous muscle in the submandibular region superficial to the submandibular gland with an accessory head of depressor labii inferioris muscle; 2. Anomalous unilateral facial muscle extending from the from the right lateral angle of mouth to coronoid process of mandible; and 3. An anomalous accessory head of temporalis muscle extending from the temporalis tendon to the posterior part of buccinator muscle.&nbsp
