The transition from learner to provider/teacher: The learning needs of new orthopaedic consultants

BackgroundGiven the relatively sudden change from learner to teacher-provider that new consultants experience and the likely clinical and managerial challenges this may pose, there is a relative dearth of research into the problems they may have in relation to their new roles, or how supported they feel by senior colleagues acting in a mentoring role. This research sought to determine new consultants views on the quality and relevance of their training, its relationship to their confidence in clinical and managerial skills and their views on mentorship by senior colleagues.MethodsDetailed postal questionnaire to new consultants using open and closed questions.Open questionnaire to established consultants to validate new consultant responses.ResultsRespondents felt their clinical training was good and were generally confident in most clinical skills although some perceived deficiencies in more complex procedures and specialist areas. Most lacked confidence in many managerial skills. These perceptions were verified by established consultants. Although no relationship was found between total training time or quality of training with confidence, extra training in specific sub-specialities improved confidence in these areas. While most established consultants thought that mentorship would be useful for new consultants, only 52% of them shared this view.ConclusionTraining and experience in management should be given greater emphasis. There may be a need for specific, targeted training in complex procedures for doctors who experience lack of confidence in these areas. Mentorship should be offered to new consultants and recognised in the job-plan of the new consultant contract.

Somatosensory evoked potentials as a means of assessing neurological abnormality in congenital talipes equinovarus.

Somatosensory evoked potentials (SSEPs) are a very sensitive measure of the functional integrity of the neuroaxis, including peripheral and central structures. When used in diagnostic mode they can provide additional information regarding the probable areas of dysfunction. SSEPs were recorded from 44 children (64 feet with congenital talipes equinovarus, CTEV), between the ages of 2 to 15 years, who had structural CTEV deformity previously treated by surgery, with no clinical evidence of neurological deficit. SSEPs were elicited after sequential and bilateral stimulation (0.1 ms/5 Hz/10 to 20 mA) of the posterior tibial nerve and the common peroneal nerve and were recorded cortically (P40). In half the children, additional recordings were conducted at the knee (N5), the first lumbar spinous process (N14), and the seventh cervical spinous process (N20). Eighteen children had abnormal responses, four children had non-reproducible responses, and 22 children had normal responses. Analysis of the data at different levels of the nervous system showed that eight children had abnormality at the spinal level. The surgical outcome was influenced by the neurological abnormality, with an excellent or good outcome in 34 of 36 feet with normal neurology and 19 of 28 feet where a deficit was present (p<0.05). These findings support the neurological theory as an etiological factor in CTEV deformity.Somatosensory evoked potentials (SSEPs) are a very sensitive measure of the functional integrity of the neuroaxis, including peripheral and central structures.

Realignment osteotomy for knee deformity in childhood

Before embarking upon any realignment osteotomy in childhood it is important to appreciate the natural history of the pathological process w4x. In benign developmental conditions a natural restitution occurs (Fig. 1). If this fails to correct the deformity surgical intervention may be required. Nowhere is this better illustrated than in the management of Blount’s disease w5–7x for even now, there is considerable debate about the timing of the pro-

Principles of Fracture Care

In childhood, bone has certain characteristics that are quantitatively different from those of the adult. First, the modulus of elasticity is relatively high and the thick periosteal sleeve adds further resistance to complete fracturing. Hence buckle (torus) and greenstick fractures are relatively common, although they may be more extensive than plain radiographs suggest. Second, it should be appreciated that bone tends to give way before ligament in the prepubertal child: apophyses and other bony points of soft tissue attachment avulse before the tendon ruptures or the ligament tears.
