Introduction:The Glenoid cavity is regarded as the head of the scapula. The morphology of glenoid cavity is highly variable. It articulates with the head of the humerus at the glenohumeral joint. Shape and dimensions of the glenoid cavity are important in the design and fitting of glenoid components for total shoulder arthroplasty. An understanding of variations in normal anatomy of the glenoid is essential while evaluating pathological conditions like osseous bankart lesions and osteochondral defects. The aim of the present study was to obtain the anthropometric data of the glenoid cavity of the scapula and to study the various shapes of the glenoid cavity which will help in management of shoulder pathology.

On the shaft of tibia surface openings for entry of blood vasculature is known as nutrient foramen which leads to nutrient canal to provide a pathway for blood vessels to reach medullary cavity. Topographical information about nutrient foramen is very crucial during various orthopedic surgical procedures. Objective: Present study is conducted to find out the number of nutrient foramina, its location and direction in relation to growing end of bone and to calculate foraminal index of human tibia. Material and Methods: In present study 61(30 right and 31 left sided) tibia bone were studied. Age and sex of the bone were unknown. Only fully intact bone without any disease were included. Surface location and direction of nutrient foramina were recorded. Total length of tibia was measured with osteomatric board. Distance of nutrient foramen from proximal end was measured with digital vernier caliper. And foraminal index was calculated. All data was tabulated and analysed statisticaly. Result: Out of total 61 tibia 95.08% of tibia had one nutrient foramen, 3.28% tibia had two foramen and 1.64% were devoid of nutrient foramen. Almost all (98.33%) of the nutrient foramina were detected on the posterior surface, only 1.67% were on lateral surface. Zone I contained 48.33% and Zone II contained 51.67% of foramina. Not a single bone had foramen in Zone III. Direction of all foramina were towards lower end of tibia except one bone. Conclusion:Thorough knowledge of morphology of nutrient foramina is necessary for preserving the nutrient arterial blood supply. Because it is very crucial in bone grafting, fracture healing, joint replacement therapy and vascularised bone micro surgeries.

Background: The Suprascapular Notch (SSN) is located at the superior edge of the scapula. The information of variations in shapes and classification can be obliging to surgeons to correlate the suprascapular nerve entrapment with a specific type of notch. The aim of this study is to document the occurrence of morphological variations in shape of suprascapular notch in dry scapulae which belongs to population of Gujarat & evaluate it with prevalence among various races of world to know its clinical significance.Methods: Total two hundred dry and intact adult human scapulae were studied of mixed sex of Indian origin derived from various medical colleges of Gujarat. All Measurements were taken by classical osteometry with the help of electronic calipers with the accuracy of 0.01mm in millimetres. Results and Interpretation:The most common type of SSN observed was Type 2, a notch that was longest in its transverse diameter. The least common type was Type 4. Type 5 SSN was absent. The most common shape was 'J' and least common was 'V'. Partial and complete ossification was also noted. Conclusion:Knowledge of anatomical variations of suprascapular notch is better for understanding location and source of entrapment syndrome. Since, the present study is performed with a limited number of dry scapulae, so there is need of further clinical, radiological and cadaveric studies.
