A rocking horse is a child's toy, usually shaped like a horse and mounted on rockers similar to a rocking chair.
Predecessors of the rocking horse may be seen in the rocking cradle, the tilting seats used during the Middle Ages for jousting practice as well as the wheeled hobby horse. The toy in its current form did not appear before the 17th century,[1] though some conflicting sources note medieval manuscripts including references to carved rocking horses, presumably of the toy kind.[2]
From the 19th century onward rocking horses became more commonly considered as child's toy. Mostly built by hobby woodcrafters, and ranging from relatively crude to finely ornamented and the toys of future kings, it was not until the late 19th century that the production became industrialised.[2]
There are two sorts, the one where the horse part sits rigidly attached to a par of curved rockers that are in contact with the ground, and a second sort, where the horse hangs on a rigid frame by iron straps the horse moves only relative to the frame, which does not move.
In 2006, the Guinness Book of World Records certified Katlinel and Les Hartness of California as having the largest hand-carved wooden rocking horse on record. This rocking horse was built in 2000 and is 7 feet 8 inches tall and weighs 1,200 pounds. It can be seen at renaissance faires, faerie festivals, and at private parties and events where up to 3 adults or 4-5 children can ride it together at one time. According to Les and Katlinel, the youngest rider has been six weeks old and the oldest, 94 years.

- Three-dimensional assessment of the dimensions of the osteoarthritic glenoid.
- Walch G1, Mesiha M, Boileau P, Edwards TB, Lévigne C, Moineau G, Young A.Author information 1Centre Orthopédique Santy- Hopital Privé Jean MERMOZ, Department of Orthopaedic Surgery, 24 Avenue Paul Santy, Lyon 69008, France.AbstractOsteoarthritis results in changes in the dimensions of the glenoid. This study aimed to assess the size and radius of curvature of arthritic glenoids. A total of 145 CT scans were analysed, performed as part of routine pre-operative assessment before total shoulder replacement in 91 women and 54 men. Only patients with primary osteoarthritis and a concentric glenoid were included in the study. The CT scans underwent three-dimensional (3D) reconstruction and were analysed using dedicated computer software. The measurements consisted of maximum superoinferior height, anteroposterior width and a best-fit sphere radius of curvature of the glenoid. The mean height was 40.2 mm (SD 4.9), the mean width was 29 mm (SD 4.3) and the mean radius of curvature was 35.4 mm (SD 7.8). The measurements were statistically different in men and women and had a Gaussian distribution with marked variation. All measurements were greater than the known values in normal subjects. With current shoulder replacement systems using a unique backside radius of curvature for the glenoid component, there is a risk of undertaking excessive reaming to adapt the bone to the component resulting in sacrifice of subchondral bone or under-reaming and instability of the component due to a 'rocking horse' phenomenon.

- Finite element analysis and physiologic testing of a novel, inset glenoid fixation technique.
- Gunther SB1, Lynch TL, O'Farrell D, Calyore C, Rodenhouse A.Author information 1Howard Memorial Hospital, Willits, CA, USA. sbgunther@aol.comAbstractHYPOTHESIS: The success of shoulder arthroplasty surgery has been limited by a common complication: glenoid implant loosening. Eccentric loading of the glenoid due to migration of the humeral head is considered to be the major cause of glenoid loosening and is referred to as the rocking-horse phenomenon. Glenoid implant loosening may cause pain, limitation of function, and the need for complicated revision surgery. Our hypothesis was that an inset fixation technique could offer increased fixation strength and minimize the effects of the rocking-horse phenomenon on glenoid loosening.

- Interface micromotions increase with less-conforming cementless glenoid components.
- Suárez DR1, Nerkens W, Valstar ER, Rozing PM, van Keulen F.Author information 1Department of Orthopaedics, Leiden University Medical Center, Leiden, The Netherlands. d-suarez@javeriana.edu.coAbstractBACKGROUND: The optimal degree of conformity between the glenoid and humeral components in total shoulder arthroplasty for best performance and durability is still a matter of debate. The main aim of this study is to evaluate the influence of joint conformity on the bone-implant interface micromotions in a cementless glenoid implant.
