Question: When was the  Anglo-Irish physician, naturalist and collector died who's niece recovered from spinal deformity due to Sarah "Crazy Sally" Mapp? 

Context paragraphs:
Coxa vara: Coxa vara is a deformity of the hip, whereby the angle between the head and the shaft of the femur is reduced to less than 120 degrees.  This results in the leg being shortened, and the development of a limp.  It is commonly caused by injury, such as a fracture.  It can also occur when the bone tissue in the neck of the femur is softer than normal, causing it to bend under the weight of the body.  This may either be congenital or the result of a bone disorder.  The most common cause of coxa vara is either congenital or developmental.  Other common causes include metabolic bone diseases (e.g. Paget's disease of bone), post-Perthes deformity, osteomyelitis, and post traumatic (due to improper healing of a fracture between the greater and lesser trochanter).  Shepherd's Crook deformity is a severe form of coxa vara where the proximal femur is severely deformed with a reduction in the neck shaft angle beyond 90 degrees.  It is most commonly a sequela of osteogenesis imperfecta, Pagets disease, osteomyelitis, tumour and tumour-like conditions (e.g. fibrous dysplasia).

Neuromechanics of idiopathic scoliosis: The neuromechanics of idiopathic scoliosis is about the changes in the bones, muscles and joints in cases of spinal deformity consisting of a lateral curvature scoliosis and a rotation of the vertebrae within the curve, that is not explained by either congenital vertebral abnormalities, or neuromuscular disorders such as muscular dystrophy.

Scoliosis Research Society: Scoliosis Research Society (SRS) is a non-profit, professional, international organization, made up of physicians and allied health personnel, whose purpose is to "care for those with spinal deformity throughout life by patient care, education, research and patient advocacy."  Founded in 1966 with 35 members, the SRS has grown to include almost 1100 spinal deformity surgeons in 41 countries, with a primary focus on providing continuing medical education for health care professionals and on funding/supporting research in spinal deformities.  Among its founding members were Dr Paul Randall Harrington, inventor of the Harrington Rod treatment for scoliosis, and Dr. David B. Levine, spine surgeon at Hospital for Special Surgery.  Harrington later served as President from 1972 to 1973, and Levine was President of the Society from 1978 to 1979.  Current membership primarily includes spinal deformity surgeons, as well as some researchers, physician assistants, and orthotists who are involved in research and treatment of spinal deformities.  Strict membership criteria ensure that the individual SRS Fellows are dedicated to the highest standards of care for adult and pediatric spinal deformities, utilizing both non-operative and operative techniques.

Gibbus deformity: A Gibbus deformity is a form of structural kyphosis, where one or more adjacent vertebrae become wedged.  Gibbus deformity can be a sequela of advanced skeletal tuberculosis and is the result of collapse of vertebral bodies.  This can in turn lead to spinal cord compression causing paraplegia.

Burst fracture: A burst fracture is a type of traumatic spinal injury in which a vertebra breaks from a high-energy axial load (e.g., traffic collisions or falls from a great height or high speed, and some kinds of seizures), with sharps of vertebra penetrating surrounding tissues and sometimes the spinal canal.  The burst fracture is categorized by the ""severity of the deformity, the severity of" (spinal) "canal compromise, the degree of loss of vertebral body height, and the degree of neurologic deficit.""  Burst fractures are considered more severe than compression fractures because long-term neurological damage can follow.  The neurologic deficits can reach their full extent immediately, or can progress for a prolonged time.

Colles' fracture: A Colles' fracture is a fracture of the distal radius in the forearm with dorsal (posterior) and radial displacement of the wrist and hand.  The fracture is sometimes referred to as a "dinner fork" or "bayonet" deformity due to the shape of the resultant forearm.  Colles fractures are the most common distal radius fractures, and they are often seen in people with osteoporosis.

Sally Mapp: Sarah "Crazy Sally" Mapp (died 1737) was an English lay bonesetter, who gained fame both by performing impressive bone-setting acts in Epsom and London, and by being a woman in a male-dominated profession.  Bone-setting was a medical practice used to manipulate and fix musculoskeletal injuries using manual force.  Mapp grew up in Wiltshire, England, and learned about the practice from her father, who was also a bone-setter.  She frequently fixed horse racing injuries, but her most famous case was fixing the spinal deformity of Sir Hans Sloane's niece.

Hans Sloane: Sir Hans Sloane, 1st Baronet, PRS (16 April 1660 – 11 January 1753) was an Anglo-Irish physician, naturalist and collector noted for bequeathing his collection to the British nation, thus providing the foundation of the British Museum.

Dianne Odell: Dianne Odell (February 13, 1947 – May 28, 2008) was a Tennessee woman who spent most of her life in an iron lung.  She contracted "bulbo-spinal" polio at age 3 in 1950 and was confined to an iron lung for the rest of her life.  Due to a spinal deformity caused by the polio, she was unable to change to a portable breathing device introduced in the late 1950s.  Odell's condition was not as severe in youth and she could spend short periods outside the machine until her 20s, from then on she needed to be in it 24 hours a day.  Caregivers could still slide Odell's bedding out of her iron lung for basic nursing care but only briefly.

Sprengel's deformity: Sprengel's deformity (also known as high scapula or congenital high scapula) is a rare congenital skeletal abnormality where a person has one shoulder blade that sits higher on the back than the other.  The deformity is due to a failure in early fetal development where the shoulder fails to descend properly from the neck to its final position.  The deformity is commonly associated with other conditions, most notably Klippel-Feil syndrome, congenital scoliosis including cervical scoliosis, fused ribs, the presence of an omovertebral bone and spina bifida.  The left shoulder is the most commonly affected shoulder but the condition can be bilateral, meaning that both shoulders are affected.  About 75% of all observed cases are girls.  Treatment includes surgery in early childhood and physical therapy.  Surgical treatment in adulthood is complicated by the risk of nerve damage when removing the omovertebral bone and when stretching the muscle tissue during relocation of the shoulder.
