Closed double-lumen suction irrigation in the management of chronic diaphyseal osteomyelitis: long-term follow-up.

Between November 1994 and June 1999, 35 patients referred to our Problem Fracture Service with chronic diaphyseal osteomyelitis were treated using a closed double-lumen suction irrigation system after reaming and arthroscopic debridement of the intramedullary canal. This is a modified system based on that of Lautenbach. Between June and July 2007 the patients were reviewed by postal questionnaire and telephone and from the case notes. At a mean follow-up of 101 months (2 to 150), 26 had no evidence of recurrence and four had died from unrelated causes with no evidence of recurrent infection. One had been lost to follow-up at two months and was therefore excluded. Four had persisting problems with sinus discharge and one had his limb amputated for recurrent metaplastic change. Our results represent a clearance of infection of 85.3% (29 of 34), with recurrence in 11.8% (4 of 34). They are comparable to the results of the Papineau and Belfast techniques, but with considerably less surgical insult to the patient.

Meniscal bearing uncemented total knee arthroplasty: early clinical results at a minimum 2-year review.

A prospective study of early clinical and radiologic outcome of the Motus (Osteo, Selzach, Switzerland) meniscal bearing total knee arthroplasty was performed. We reviewed the first 75 consecutive prostheses in 62 patients, implanted over a 4-year period. The mean follow-up was 2.5 years. Average preoperative knee score was 97 out of 200 (Knee Society score, 43; functional score, 54) and at 2-year review was 179 out of 200 (Knee Society score, 87; functional score, 92). Average postoperative flexion at 2 years was 113 degrees. No meniscal bearing subluxation, dislocation, or breakages occurred. Radiologically, there was no evidence of subsidence or osteolysis. Our results support the continued use of this meniscal bearing knee prosthesis. It is important to confirm, however, an equal flexion and extension gap without proximal joint line migration.

Intramedullary femoral nailing: removing the nail improves subjective outcome.

Intramedullary nailing has become an established treatment for femoral fractures. We reviewed the subjective and objective outcome of locked intramedullary nailing since its introduction to our unit in 1988. The outcome was assessed subjectively using the Short Form 36 (SF 36) health questionnaire and objectively by clinical, radiological and case note review. From 1988 to 1995, 220 intramedullary femoral nails were inserted at the North Staffordshire Royal Infirmary. Of these we were able to match the SF 36 questionnaire and case review of 91 patients. Fifty-six patients were male and 35 female with an average age of 40. Acute trauma accounted for 86 cases (six with an injury severity score >15 and seven open injuries). There was a 24% incidence of minor complications; there were no deep infections and no major complications. All cases recorded subjective scores within the normal range but 34 symptomatic patients who had their femoral nails removed (mainly for persistent pain or prominent metalwork) recorded noticeably higher scores in all eight assessment areas. Intramedullary nailing for femoral fractures is a technically demanding procedure and results in both a good objective and subjective outcome. It is associated with a low rate of major complications but a relatively high rate of minor complications. We conclude that the removal of intramedullary femoral nails is justified in symptomatic patients. It results in an improved subjective outcome and has a low complication rate.

"Silent" transverse patellar fracture following anterior cruciate ligament reconstruction.

Patellar fracture is a rare but specific complication of anterior cruciate ligament reconstruction using bone-patellar tendon-bone autograft. When this complication occurs, early internal fixation is recommended and need not compromise the outcome. We report 2 cases of displaced transverse patellar fracture occurring after reconstruction but which were not diagnosed and presented with late sequelae.

Vertical transtalar Steinmann pin fixation for unstable ankle fractures.

Ankle fractures are common injuries and can usually be managed by either cast immobilisation or open reduction and internal fixation. Occasionally, both of these methods are contra-indicated. In such cases, one solution is the use of a vertical transtalar Steinmann pin to stabilise the fracture. Over the last 7 years, we have managed 8 patients with severe ankle fractures using vertical transtalar Steinmann pin fixation. The median age of these patients was 76 years (range, 35-94 years). This method was used in two patients with open contaminated wounds, in 5 with atrophic and blistered skin, and in one following failure of internal fixation in a patient with atrophic skin. In all patients, a satisfactory reduction was achieved and maintained after removal of the pin. Although all patients began to develop osteo-arthritic changes secondary to their original fractures, no complications were directly attributable to the use of the pin. In unstable ankle fractures where damage and contamination of soft tissues would preclude internal fixation, we recommend the use of vertical transtalar Steinmann pin fixation.

The audit of orthopaedic trainee teaching improves supervision rates.

Inefficiency in surgical training has been identified as a result of low rates of supervision, with direct teaching of operating by consultants occurring in less than 20% of cases in papers dealing with general surgery and cardiac surgery training. The introduction of an audit system in an orthopaedic training programme was associated with an improvement of teaching from an already high 30% to 40% of cases. A logbook programme was introduced which allows easy analysis of the distribution of experience on an anatomical basis.

The intercruciate band of the human knee. An anatomical and histological study.

Thirty cruciate ligaments were retrieved from either cadavers or limbs which had been amputated. Each specimen was sectioned and stained to demonstrate the presence of collagen, nerves and vessels. All 30 specimens contained an interconnecting band of collagen fibres between the anterior and posterior cruciate ligaments. Vascular structures were present in all specimens and nerve fibres were identified in 26 (86%). We have called this structure the 'intercruciate band'. The anterior and posterior cruciate ligaments should no longer be thought of in isolation, but together as a 'cruciate complex'.

The motivation to learn: efficacy and relevance of the Oswestry postgraduate orthopaedic training programme.

The efficacy and relevance of medical education has come under increased scrutiny in recent years. The shortening of basic surgical training and the introduction of 'seamless' higher surgical training has placed greater emphasis on the quality of education provided/facilitated by trainers. Additionally, study leave budgets are under increasing pressure from trainees wishing to attend courses or conferences, and regional postgraduate deans who wish to see a proportionally greater amount of training on an 'in-house' basis. Against this background we have reviewed the learning opportunities available on the Oswestry postgraduate programme to see if these opportunities provide adequate motivation to learn for the trainee.

Arthroscopic debridement of external fixator pin tracts.

Major external fixator pin tract infection can be managed by curettage, overdrilling or excision of the pin tract. An alternative is arthroscopic debridement which allows thorough curettage with the advantage of direct inspection of the pin tract to ensure clearance of all necrotic tissue from the tract base and walls. To date, arthroscopic pin tract debridement has been used successfully to manage 25 pin tracts in six patients. Adequate visualization of the pin tract throughout its course was possible in all cases. Two patients subsequently underwent intramedullary nailing without complication. No recurrent infection has occurred at review at 13 months.

An audit of theatre scrubrooms in a district general hospital.

While much has been written on surgical theatre design, little can be found on the design of theatre scrubrooms. An audit of theatres at a modern district general hospital (DGH) revealed that only one scrubroom had the minimum free floor space required and none complied with other baseline parameters. A survey of surgeons revealed that 60% had to re-scrub because their hands had desterilised through insufficient scrubroom space. The implications for hygiene hazards are clear. We review the literature and outline the basic dimensions which should be incorporated in the design of modern theatre scrubrooms.

Formal assessment of the surgical trainee: a review of eight years experience at St Lawrence Hospital, Chepstow.

In light of the proposals for a continuum of higher surgical training, we reviewed an 8-year experience of formal assessments of surgical trainees. We undertook a retrospective analysis of 34 completed assessment forms, retrieved from records, and a postal questionnaire of 54 former (and current) trainees. Our study revealed that all trainees agreed in principle with formal assessments. Eighty-one per cent found their assessment either useful or excellent and a further 17 per cent found the advice received was influential in their careers. The consultants, in turn, were able to modify the training programme as a result of constructive feedback. Based on our experience we recommend formal assessments of surgical trainees as an important and rewarding part of an impartial peer review system within a continuum of higher surgical training.
