Abstract

Introduction:Bicipital groove (BG) in the proximal part of humerus is an indentation formed between the lesser and greater tubercle forms the lateral edge of lesser tubercle forms the medial border of bicipital groove. It contains the long head of the biceps brachii muscle, its synovial sheath and an ascending branch of the anterior circumflex humeral artery. The depth and width are very important in retention of tendon of biceps. Several authors reported greater incidence of sublaxation and dislocation of tendon of biceps when the BG is shallow. Morphometry of bicipital groove may influence the functions of surrounding structure leading to various pathological condition. BG is important landmark for replacement of prosthesis of shoulder. Thus knowledge of BG is highly useful in prosthetic sizing, positioning and designing. Aim and objectives – To study the morphometry of bicipital groove (BG).Subjects and Methods:Present study was done on 50 humeri in PGIMS Rohtak in which 25 were of right side and 25 left side. The length, width, depth of BG and the length of the medial and lateral wall of intertubercular sulcus were measured using digital Vernier caliper. Data was recorded separately for right and left humeri then it was analyzed statistically using independent t test, p value <0.05 were considered significant. The data was presented as mean ±SD.Results:In present study above stated parameters were measured which came out to be statistically insignificant except the width of BG, which showed the statistical difference. The p value for the width of BG was < 0.05. Conclusion:Knowledge of BG is highly useful in prosthetic sizing, positioning and designing. The present study is an attempt to determine the morphometric parameters of BG in terms of length of medial wall, lateral wall, length of BG, width and depth of BG. The data on morphometry of BG will be of utmost use for radiologists, orthopedic surgeons and physiotherapists.

Highlights

Bicipital groove (BG) in the proximal part of humerus is an indentation formed between the lesser and greater tubercle forms the lateral edge of lesser tubercle forms the medial border of bicipital groove.[1]
It contains the long head of the biceps brachii muscle, its synovial sheath and an ascending branch of the anterior circumflex humeral artery.[2]
The bicipital groove in the humerus lodges the tendon of biceps brachii in a tunnel formed by the fibrous band i.e. transverse humeral ligament

Summary

Introduction

Bicipital groove (BG) in the proximal part of humerus is an indentation formed between the lesser and greater tubercle forms the lateral edge of lesser tubercle forms the medial border of bicipital groove.[1]. The humerus moves on the tendon of the long head of the biceps in all movment of the upper extremity.[3,4,5] Sublaxation and dislocations of the biceps tendon are more common in people with a shallow intertubercular sulcus.[6,7] Morphometry of bicipital groove may influence the functions of surrounding structure leading to various pathological condition.[8,9] Rockwood and Mastsen mentioned that humans are unique among primates in presenting marked variation in the configuration of bicipital groove.[10,11] BG is important landmark for replacement of prosthesis of shoulder. Lesion affecting the tendon of long head of biceps brachii have been postulated to be among the most frequent causes of pain and disability in shoulder This pain may be caused by rotator cuff, supraspinatus and biceps tendon diseases.[14] an attempt has been made to examine the length, width, depth of BG and length of medial and lateral wall of BG
