L Distal Joint Capsule Arm 1
Like any synovial joint, the capsule is dual layered. The fibrous outer layer attaches to the radius, ulna and the proximal row of the carpal bones. The internal layer is comprised of a synovial membrane, secreting synovial fluid which lubricates the joint. The joint capsule is vital to the function of synovial joints. It seals the joint space, provides passive stability by limiting movements, provides active stability via its proprioceptive nerve endings and may form articular surfaces for the joint. It is a dense fibrous connective tissue that is attached to the bones via specialised attachment zones and forms a sleeve around the joint. It varies in thickness according to the stresses to which it is subject, is locally thickened to form capsular ligaments, and may also incorporate tendons. The capsule is often injured, leading to laxity, constriction and/or adhesion to surrounding structures. Source

L Retinaculum
A retinaculum (plural retinacula) is a band around tendons that holds them in place. It is not part of any muscle. Its function is mostly to stabilize a tendon. A retinaculum refers to any region on the body in which tendon groups from different muscles pass under one connective tissue band. Wrist retinacula include the flexor and the extensor retinacula of the hand. Ankle retinacula include the peroneal retinacula and the flexor, superior extensor, and inferior extensor retinacula of the foot. If a retinaculum is injured, it may lead to an impairment of tendon functionality. If the peroneal retinaculum tears or stretches, it may cause the peroneal tendons to detach from the fibula. This may cause damage to the tendons and impair their functionality, leading to a condition known as peroneal tendon dysfunction. During or following arthroscopic knee surgery, the quadriceps tendon may rupture due to the release of the lateral retinaculum. This complication is relatively rare and may manifest up to five weeks after the injury. To reduce the complications from retinaculum surgery, a procedure was developed that incorporates medial patellofemoral ligament overlap in addition to lateral retinaculum release. Source

L Thumb Capsule
The joint capsule of the thumb is fibrous and durable, and allows for great mobility. There are nine interphalangeal joints in each hand, two on each finger and one in the thumb. The thumb joint has two collateral ligaments as well as the capsule, which is lined by a synovial membrane. The collateral ligaments are called the anterior and posterior ligaments. They are responsible for reinforcing the thumb. Flexion and extension occur parallel to the palm of the hand. As flexion occurs, there is medial rotation of the metacarpal. The joint capsule of the thumb is similar to that of the fingers. The only notable difference being the articular surface of the metacarpal head is smaller and consequently less movement is available. It is reinforced by two cartilage covered sesamoid bones on its volar surface. The sesamoids also increase the leverage actions and there is very little hypertension compared with the fingers. The ulnar side of the joint is most susceptible to trauma. Source
L Trapeziometacarpal Ligament
The primary trapeziometacarpal ligament is also known as the anterior oblique ligament. It stabilizes the thumb’s trapeziometacarpal joint. This joint connects the trapezium to the first metacarpal bone. The trapezium is a small carpal bone located below the thumb. The trapeziometacarpal ligament originates on a ridge-like bump on the trapezium. This is known as a tubercle. It inserts into the base of the first metacarpal bone. The ligament is stretched when the thumb is extended or rotated inward. It provides mobility but it also prevents dislocation. In some cases, it may remain partly uninjured even if the joint is dislocated. Osteoarthritis of the joint is common. Serious cases can be treated with surgery. The most common surgical technique involves trapeziectomy. This refers to removing the trapezium. Source
L Radial Collateral Carpal Ligament
The scaphoid bone is one of the small bones of the wrist, which are known as carpal bones. It is located between the hand and forearm on the radial side (the side with the thumb). It is about the size and shape of a cashew. The radial styloid process is a conical bump located on the radius, a bone of the lower arm. The radial carpal collateral ligament connects the scaphoid bone and the radial styloid process. This ligament prevents the wrist from bending too far to the side, away from the thumb. The scaphoid bone takes a lot of force to break. Nonetheless, it is the most commonly fractured bone of the wrist. Fractures of the scaphoid often occur during sporting activities, when someone falls on their outstretched hand and hyperextends their wrist. Fractures of the scaphoid are usually slow to heal, due to limited blood circulation. Damage to the bone can cause damage to the radial carpal collateral ligament. Improper healing of fractured bones and stretched or torn ligaments is a primary cause of osteoarthritis. Arthritis itself can then cause further deterioration of the ligaments. Source

Muscles that contribute to function are all supinator (Biceps Brachii, Brachioradialis, and Supinator) and pronator muscles (Brachioradialis, Pronator Quadratus, and Pronator Teres).
L Palmar Metacarpal Ligament 1
The hand of the human body consists of carpal bones and metacarpal bones. The carpal bones are rounded or triangular-shaped bones located at the top of the hand, below the fingers. The metacarpal bones are the longer bones that create the fingers. The palmar metacarpal ligament serves as the connective tissue, bonding the two types of bones. When two bones meet, the bones need a ligament covering to move and be flexible. The term palmar refers to the palm of the hand, or the bottom side of the hand. The ligament allows the hand to grasp and hold items. The ligament is located on the underside of the hand, in the space between the metacarpal bones and carpal bones. The palmar metacarpal ligament is slightly concave in nature, which means it dips low in the center. On top of the ligament are flexor tendons, which increase flexibility in the hand. The area also has interosseous muscles, which are thin muscles that control the mobility of the fingers. Source
L Palmar Carpometacarpal Ligament 2
The palmar carpometacarpal ligament is a wrist ligament that is part of the volar deep ligaments. The term volar is used to mean the front part of the hand. Ligaments, or joints, are conjoining tissues that keep bones together. Wrist ligaments function collaboratively to enable hands and fingers to move and hold objects. Carpometacarpal joints have five joints with very limited motion; these are supported by dorsal and palmar ligaments. While dorsal ligaments control bending action, palmar ligaments limit extension. The term palmar refers to the palm, or the grasping side of the hand. As they are not synovial joints, the second to fifth joints’ freedom of movement is severely restricted. However, the second and third joints are basically static and usually assumed to have no freedom at all. The palmar carpometacarpal ligament is among the soft tissues of the wrist. It connects the distal row of carpals to the proximal ends of the metacarpal bones to assist both the flexion and extension actions. Source
L Proximal Joint Capsule Arm 3
Like any synovial joint, the capsule is dual layered. The fibrous outer layer attaches to the radius, ulna and the proximal row of the carpal bones. The internal layer is comprised of a synovial membrane, secreting synovial fluid which lubricates the joint. The joint capsule is vital to the function of synovial joints. It seals the joint space, provides passive stability by limiting movements, provides active stability via its proprioceptive nerve endings and may form articular surfaces for the joint. It is a dense fibrous connective tissue that is attached to the bones via specialised attachment zones and forms a sleeve around the joint. It varies in thickness according to the stresses to which it is subject, is locally thickened to form capsular ligaments, and may also incorporate tendons. The capsule is often injured, leading to laxity, constriction and/or adhesion to surrounding structures. Source
