Introduction:

Mayo 2A Olecranon fractures are traditionally managed with a tension band wire device (TBW) but locking plates may also be used to treat these injuries.

Injuries of the posterolateral corner (PLC) of the knee are uncommon, but can lead to chronic disability from persistent instability and resultant articular cartilage degeneration if not appropriately treated. Although numerous reconstructive techniques have been described in the literature, there is no consensus on a single surgical approach due to a lack of consistent, long-term clinical outcomes. Nonanatomic reconstructions, in particular, have produced variable results, while anatomic reconstructions offer the most promise by restoring normal knee stability and kinematics and are now favoured by most.

We describe the novel use of the BICEPTOR™ Tenodesis screw (Smith & Nephew) as an effective and technically straight forward means of performing a PLC reconstruction. We describe the technique and present the first 10 consecutive cases from a single surgeon series. All of the patients had a positive dial test pre-operatively with increased external rotation of 10 degrees or more at 30 degrees of knee flexion indicating clinical PLC injury. They all had the PLC reconstructed at the same time as an arthroscopic ACL reconstruction. Mean time from injury to surgery was 4 months (range 2–12). Patients were seen in clinic at maximum follow-up (11.1 months mean, range 6–24 months) and assessed clinically using the dial test at 30 and 90 degrees of knee flexion. Lysholm Knee Questionnaire and Tegner Activity Scale were also performed at maximum follow-up. Mean Lysholm Score was 68 (range 32–96). Mean Tegner Score pre-operatively was 3.5 (range 3–6) and at maximum follow-up was 4.5 (range 3–7). Of particular note only one patient reported any symptoms at all of giving way at maximum follow-up. Dial test was negative on all patients.

Further work is warranted but we describe this as an effective and straight forward means of performing a PLC reconstruction.

Whilst the SIGN Guidelines state that the use of prophylactic antibiotics in surgery unequivocally reduces major morbidity, reduces hospital costs and is likely to decrease overall consumption of antibiotics they state the chosen antibiotics must reflect local, disease-specific information about the common pathogens and their antimicrobial susceptibility.

Growing healthcare concern regarding the rates of Clostridium Difficile (C. Diff) within the hospital setting have led to rationalised and better streamlined prescribing practice within the NHS. In NHS Lanarkshire this led to revised guidelines for prophylactic antibiotic use in Orthopaedics in 2010. Routine use of 3^rd generation Cephalosporin has been replaced by Flucloxacillin 1g and Gentamicin 1mg/kg.

Anecdotally the surgeons within our department were concerned that they were recognising more post-operative renal impairment than before 2010.

Our study took 902 consecutive cases treated surgically with either Total Hip Replacement, Total Knee Replacement, Dynamic Hip Screw for fracture and Hemiarthroplasty for fracture since the introduction of the new antibiotic policy. We compared this with a similar number of cases treated with the same operations pre-2010. We looked at the pre admission Urea & Electrolystes compared with immediate post-operative results and applied the definition of Acute Kidney Injury (AKI) as defined by the Acute Kidney Injury Network. A. A rapid time course (less than 48 hours) and B. Reduction of kidney function either as an absolute increase in serum creatinine of ≥26.4μmol/l (≥0.3 mg/dl) or a percentage increase in serum creatinine of ≥50%. Based on this definition we found an increased rate of AKI of 13.7% after the introduction of the use of Gentamicin from 9.8% before its routine use.

We wish to highlight that the routine widespread use of Gentamicin may be increasing the rate of acute renal dysfunction seen in Orthopaedic patients undergoing major surgery.

Background: The painful 1st metatarso-phalangeal joint (MTPJ) is a common presentation in outpatient clinics. Options for treatment include arthroplasty and arthrodesis. Previous MTPJ replacement implant designs have had poor mid-term success. The Moje prosthesis was designed to overcome some of the problems with earlier implants, and employs ceramic bearing surfaces and a press-fit tapered stem design. Previous studies have reported good early results in small numbers of patients.

Methods: Between February 2002 and December 2006 the senior author implanted 55 components in 48 patients. AOFAS hallux scores and satisfaction scores (0 to 10) were recorded at follow-up. Radiographs were analysed for component alignment, implant bone coverage and subsidence. The mean age of patients at implantation was 56 years (34–77). Average follow-up was 42 months (15 to 74).

Results: There were no patients lost to follow-up. Average AOFAS score was 72 (25 to 100) and satisfaction score was 8.2 (range 1 to 10). 82% stated they would have the same procedure again and 82% reported minimal or no pain. There were no deep infections but 35% of patients reported altered sensation. Four implants have been removed (8%) because of worsening pain and implant loosening. 50% of metatarsal implants and 80% of phalangeal implants were implanted within 5 degrees of the long bony axis. Average bony coverage was 80%, resulting in subsidence of 90% of metatarsal and 70% of phalangeal implants at follow-up.

Discussion: Despite the poor radiographic appearance in the majority of cases, this procedure has good clinical outcome at the mid-term stage with 92% implant survival. The long-term clinical significance of the radiographic appearances is currently unknown. Improved surgical technique, including better bony coverage, may reduce the risk of implant subsidence.
