Wrist & hand

Tendons

Extensor carpi ulnaris tendon
The tendon on the little-finger side of the back of the wrist. How a groove and a small sleeve hold it, how it slips or wears in racquet and club sports, and what case series found afterwards.
First dorsal compartment tendons
The two thumb tendons that share a tunnel on the thumb side of the wrist. How the tunnel is built, how wrist position changes gliding inside it, and what studies of De Quervain's found there.

Scapholunate ligament
The short ligament that ties the scaphoid to the lunate, two neighbouring wrist bones. How its three parts are built, how falls tear it, and what small studies report about tears over time.
Ulnar collateral ligament of the thumb
The band on the little-finger side of the thumb's metacarpophalangeal joint that holds it against sideways opening. Its two parts, how falls and ski poles tear it, the Stener lesion, and what laboratory tests found.

Triangular fibrocartilage complex
The disc and ligaments on the little-finger side of the wrist. What they are made of, how they share load and steady the forearm bones, how they wear and tear, and what studies found about healing.

Distal radius
The wrist end of the radius, the forearm bone on the thumb side. How it is shaped, how much load it carries, who breaks it and how, how it mends and builds up with loading, and what attaches to it.
Scaphoid
A boat-shaped wrist bone on the thumb side that links the two rows of wrist bones. Where it sits, how blood reaches it, who breaks it and how, and how long its parts take to join again.

Wrist joint
Eight small bones and the joints between them and the forearm. How the wrist moves, how load crosses it, how it is hurt in falls and sport, what studies of gymnasts found, and what connects to it.

Wrist curl
Bending the wrist against a load. What studies measured it working in the forearm and around the carpal tunnel, how the wrist flexors changed with training, and what studies of inner-elbow pain found.

Wrist flexor stretch
A forearm stretch that bends the wrist and fingers back. What studies of forearm-flexor stretching and wrist-extension positions measured, from muscle stiffness and grip to the median nerve.

Median nerve
The nerve that runs down the middle of the arm to the thumb side of the hand. Where it runs, how it slides as the arm moves, where it gets squeezed, and what studies report about recovery.

Carpal tunnel syndrome
Squeezing of the median nerve where it passes through the wrist. How guidelines define it, who it affects, and what studies of splints, injections, nerve-gliding exercise and surgery found.
De Quervain's tenosynovitis
A painful condition of two thumb tendons where they pass the thumb side of the wrist. How reviews describe it, who it affects, and what studies of injections, splints, exercise and surgery found.
Distal radius fracture
Breaks of the lower end of the radius, the forearm bone on the thumb side. The patterns sources name, who they affect, the first year afterwards, return to sport and work, and what trials of wires, plates, casts and bandages found.
Scaphoid fracture
A break of the scaphoid, a wrist bone on the thumb side. Where it breaks, who breaks it, what follows when it does not join, and what trials of surgery against a cast and studies of return to sport found.
Skier's thumb
A partial or complete tear of the ulnar collateral ligament at the base of the thumb. How papers define and name it, who it affects, and what studies of splints, casts, operations and return to sport found.
Wrist sprain
A label for a wrist injury whose X-rays show no break. How studies define it, what MRI finds behind it, who it affects, and what studies of casts, wrist guards and ligament surgery found.

Bench press
A barbell pressing exercise. What studies measured it working, from the chest and triceps to the shoulder, how bench angle and grip width change that, what ten weeks of training changed, and how studies progressed it.
Push-up
A bodyweight pressing exercise done face down on the hands. How much body weight studies measured on the hands, which muscles work, how hand position and unstable surfaces change that, and what training trials found.
Wrist extension
Lifting the back of the hand against resistance. What studies measured it working in the forearm, what one hard bout did to the muscles, and what studies of people with outer-elbow pain found.
