- Abstract: The aim of this study was to elucidate the intramuscular arborization of the teres minor muslce for effective botulinum neurotoxin injection. Twelve specimens from 6 adult Korean cadavers (3 males and 3 females, age ranging from 66 to 78 years) were used in the study. The reference line between the 2/3 point of the axillary border of the scapula (0/5), where the muscle originates ant the insertion point of the greater tubercle of the humerus (5/5). The most intramuscular neural distribution was located on 1/5–3/5 of the muscle. The tendinous portion was observed in the 3/5–5/5. The result suggests the botulinum neurotoxin should be delivered in the 1/5–3/5 area of the teres minor muscle.
