Anatomical measurements of the distal clavicle are important in the design of clavicular implants for
fixing clavicular fractures and reconstruction of the coraco-clavicular complex in acromio-clavicular joint
dislocations. These measurements show population variations however, little data exists from the African
population and none for the Kenyan one. One hundred and eighty unpaired dry adult human clavicles
were obtained from the Department of Human Anatomy, University of Nairobi. The length of clavicle and
distance of conoid and trapezoid tuberosities from the distal end were measured using a ruler. The
superoinferior thickness of the distal end was measured using a vernier caliper. The mean clavicle length
was 148.57±12.63mm. The left clavicle was longer (150.4mm) than the right one (146.8mm). Conoid
tubercle (CT) and trapezoid tuberosity (TT) were 39.52±5.93mm and 17.96±3.42mm respectively from
the lateral edge of clavicle. These distances correlated positively with the length of clavicle and occupied
0.3 and 0.15 of total clavicular length respectively. The supero-inferior thickness of the lateral edge was
10.09±2.36mm. The distance of CT and TT positively correlated with clavicular length. The CT lies at a
junction of lateral one third and medial 2/3 while the TT is midway between CT and lateral end. Designers
of clavicular implants should consider these measurements and surgeons involved in fixation of
acromoclavicular joints fractures.
