Introduced by Mr A Catterall, Consultant Orthopaedic Surgeon, Royal National Orthopaedic Hospital. Directed by Trevor A Scott. Made for British Postgraduate Medical Federation. Film sequences from John Collins, Photographic Department, Royal National Orthopaedic Hospital. Made by University of London Audio-Visual Centre.

This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and 1980s, thus constituting a contemporary medical-historical archive of great interest. The lectures mostly take place in a small and intimate studio setting and are often face-to-face. The lecturers use a wide variety of resources to illustrate their points, including film clips, slides, graphs, animated diagrams, charts and tables as well as 3-dimensional models and display boards with movable pieces. Some of the lecturers are telegenic while some are clearly less comfortable about being recorded; all are experts in their field and show great enthusiasm to share both the latest research and the historical context of their specialist areas.

Segment 1 Mr Catterall introduces the subject of congenital dislocation of the hip with a brief history of its discovery. He goes on to review the work of Wynne-Davies which looks at the incidence of congenital dislocation and its associated factors. The difference between early and late diagnosis of congenital dislocation is summarised in a table and some of the causes are broached.

Segment 2 Catterrall discusses the risk of genetic inheritance of congenital dislocation and shows a table of statistics based on genetic inheritance. He then shows drawings depicting a normal hip and a dislocated hip and describes the differences between the two in depth. Time start: 00:06:03:20 Time end: 00:11:42:00 Length: 00:05:38:05

Segment 3 Catterrall focuses on diagnosis, particularly early diagnosis. He suggests that any child with a family history and certain physiological signs (listed on a table) should be x-rayed. We are shown a series of still photographs of children with dislocated hips - Catterrall describes each one in turn. An x-ray of a dislocated hip is shown and Catterrall describes what signs a clinician would look out for on this kind of x-ray. Time start: 00:11:42:00 Time end: 00:16:11:21 Length: 00:04:29:21

Segment 4 We see a short film of an 18-month-old infant with congenital dislocation of the hip, walking. Catterrall describes the abnormal features of its walk. He then goes on to discuss bilateral dislocation of the hip and shows still photographs and an x-ray of a young girl with this kind of dislocation. Catterrall begins to discuss the principles of treatment for congenital dislocation and shows a table listing these. He introduces traction as a treatment, saying it is the simplest method to use. Time start: 00:16:11:21 Time end: 00:20:07:15 Length: 00:03:55:19

Segment 5 Catterrall focuses on traction as a treatment for congenital dislocation of the hip. He shows a series of still photographs of an infant in traction and describes how it works. We see the x-ray of an infant with full abduction, then in cross traction, then in a repeat x-ray following traction, Catterrall describes the changes that have occurred. Next we see a short film of a child being examined under anaesthetic, then shown in a plaster cast and in a series of follow-up x-rays; Catterrall describes in depth the changes in the shape and position of the hip. Time start: 00:20:07:15 Time end: 00:26:35:00 Length: 00:06:27:10

Segment 6 Catterrall shows a series of x-rays showing cases before and after treatment. Catterrall describes what sort of traction each case had and talks in depth about the physiological changes made to the hip. He then goes on to discuss open reduction surgery and refers to a table listing indications for this procedure and factors prohibiting it as an option. Time start: 00:26:35:00 Time end: 00:30:03:00 Length: 00:03:28:00

Segment 7 Catterrall refers to a series of still photographs showing an open reduction procedure, he describes the procedure in depth. We see x-rays showing a unilateral dislocation before and after surgery and Catterrall points out the main changes that have occurred following surgery. Time start: 00:30:03:00 Time end: 00:35:30:00 Length: 00:05:27:00

Segment 8 Follow-up at the end of primary treatment is now discussed. Catterrall points out that this is important so that the hip doesn't re-dislocate. We see a series of x-rays following up on the progress of various cases after treatment. Catterrall describes each case in detail. Time start: 00:35:30:00 Time end: 00:40:37:14 Length: 00:05:07:14
