Summary
Basketball players can develop acute suprascapular nerve lesions from repetitive micro-trauma during play, leading to arm abduction and rotation issues. Recovery is typically quick with rest.
Area of Science:
- Sports Medicine
- Neurology
- Orthopedics
Background:
- Suprascapular nerve lesions are uncommon in athletes without direct trauma.
- Repetitive shoulder movements in basketball may cause nerve traction injuries.
Observation:
- A basketball player presented with an acute suprascapular nerve lesion without prior shoulder trauma.
- Clinical symptoms included inability to abduct the arm and difficulty with external rotation.
- Muscle atrophy in the supraspinatus and infraspinatus was observed.
Findings:
- Electrophysiological studies revealed prolonged nerve conduction latency to both supraspinatus (8.0 ms) and infraspinatus (8.5 ms) muscles.
- Compound muscle action potentials were within normal limits (1.224 mV and 1.237 mV, respectively).
- The lesion was attributed to nerve traction over the coracoid notch during forceful movements like dunking.
Implications:
- This case highlights a novel mechanism of acute neuropathy in basketball players due to repetitive micro-trauma.
- Early recognition and rest may lead to spontaneous and complete recovery.
- Awareness of this condition is crucial for athletes and sports medicine professionals to ensure proper diagnosis and management.

01:23Muscles of the Shoulder
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:22Spinal Nerves: Plexus I
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
