Neck of femur fracture: who gets a total hip replacement? A review of 230 eligible patients.

PURPOSE: To investigate patient-specific factors that predict Total Hip Replacement (THR) in patients with fracture neck of femur (NOF), fulfilling the National Institute of Health and Care Excellence (NICE) criteria. METHODS: Hip fracture database from a district general hospital and university hospital was retrospectively reviewed to identify patients fulfilling NICE criteria for THR after fracture NOF. Patient demographics, Nottingham Hip Fracture score (NHFS), complications, re-operations, revision, 30 days and one-year mortality was obtained from patient-records. Independent predictors correlating with the outcome of surgery were identified. A logistic regression analysis was used to predict the type of surgery in these patients. RESULTS: A total of 230 (114 WMH and 116 MH) were identified; 133 (57.8 per-cent) received hip hemiarthroplasty (HA), and 97 (42.2 per-cent) received THR. Patients receiving THR (mean 73.5 years, 95% CI 72-74.8) were significantly younger in comparison to patients receiving HA (mean 81.7 years, 95% CI 80.5-82.8). A negative correlation is noted between NHFS and type of surgery (Pearson's correlation - 0.537, p < 0.01), implying higher NHFS decreased the likelihood of receiving THR. Regression analysis showed NHFS (p-0.001) and walking ability (p-0.001) as significant predictors for the type of surgery (Nagelkerke R2-0.472). A log-rank test showed higher estimated survival time in patients with THR in comparison to HA (p-value 0.002). CONCLUSIONS: NHFS and walking ability can be used as an adjunct to the NICE criteria for selecting patients for THR after fracture NOF. Carefully selected patients treated with THR survive longer and have a better outcome in comparison to HA.

The effects of a new Tendo-Achilles Pathway (TAP) on an orthopaedic department- A quality improvement study.

BACKGROUND: Achilles tendinopathy is a common pathology that is considered difficult to treat. At a time of austerity in the NHS it is essential to have carefully designed pathways that are monitored in terms of cost and effectiveness. However, a paucity of evidence exists for what the "best value" dedicated "joined up" pathway of care is for this difficult condition. OBJECTIVES: Design, implement and evaluate the impact of a new therapist lead pathway for Tendon- Achilles Pain (TAP).  METHODS: Process mapping, driver diagrams, stakeholder analysis and a series of Plan-Do-Study-Act cycles were used to design and implement TAP. To assess the impact of TAP, data was compared on whole system measures for 46 patients treated with referral to the traditional service (without TAP) and 46 patients managed according to the newly designed pathway (with TAP). A cost analysis was also conducted. RESULTS: A quality improvement approach led to the successful design and implementation of a therapist lead TAP. The impact of TAP included positive effects on patient satisfaction, a decrease in duplication of treatments, investigations and inappropriate reviews with consultants. No safety concerns were found. TAP was also £44,000 cheaper per annum than the previous service. CONCLUSION: Collaboration between orthopaedic and therapy services has resulted in a standardised pathway of care for patients with an Achilles tendinopathy.  It has removed unwanted variation, provided an opportunity to monitor the outcomes of treatments and resulted in decreased cost for the health board.

Intermittent foot claudication caused by a dynamic compression of the posterior tibial artery.

A young adult presented with an atypical intermittent foot claudication caused by a dynamic compression of the posterior tibial artery by a ganglion. This case highlights the diagnostic challenges when dealing with an entrapment syndrome. Subsequent open surgical treatment was successful, and the patient has made a good recovery.

What is the best clinical test for Achilles tendinopathy?

BACKGROUND: Differential diagnosis of Achilles pathology is demanding. This study evaluates the diagnostic accuracy of clinical tests identified for a chronic mid body Achilles tendinopathy. Ultrasound scanning provides the reference standard. METHODS: Twenty-one participants with, and without, an Achilles tendinopathy, had an ultrasound scan followed immediately by the application of ten clinical tests. The accuracy and reproducibility of each test was determined. RESULTS: The most valid tests are; pain on palpation of the tendon (sensitivity 84%, specificity 73%, kappa 0.74-0.96) and the subjective reporting of pain 2-6 cm above the insertion into the calcaneum (sensitivity 78%, specificity 77%, kappa 0.75-0.81). CONCLUSION: Only location of pain and pain on palpation were found to be sufficiently reliable and accurate, to be recommended for use.

Responsiveness and validity of the SF-36, Ankle Osteoarthritis Scale, AOFAS Ankle Hindfoot Score, and Foot Function Index in end stage ankle arthritis.

BACKGROUND: We examined four commonly used scores, the SF-36, the Ankle Osteoarthritis Scale (AOS), the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Score, and the Foot Function Index (FFI) to determine their responsiveness and validity. METHODS: Patients with end stage ankle arthritis were recruited into a prospective multicenter cohort study and baseline and one year outcome scores were compared. The Standardized Response Mean and Effect Size for the AOS, AOFAS, and FFI were calculated and the three region- or disease-specific scores were compared with the SF-36 to determine their criterion validity. RESULTS: All four scores showed acceptable responsiveness, and when using the validated SF-36 as the standard the three region or disease specific scores all showed similar criterion validity. CONCLUSION: All four scores are responsive and can be considered for use in this population. The objective component of the AOFAS Ankle Hindfoot Score may make it harder to perform than the other three scores which have subjective components only, and as yet its objective component has not been shown to demonstrate reliability. We recommend use of a purely subjective score such as the Ankle Osteoarthritis Scale or Foot Function Index as the region- or disease-specific score of choice in this population. As the SF-36 shows acceptable responsiveness, using it alone could also be considered.

A comparison of the long gamma nail with the sliding hip screw for the treatment of AO/OTA 31-A2 fractures of the proximal part of the femur: a prospective randomized trial.

BACKGROUND: Controversy exists with regard to whether to treat AO/OTA 31-A2 fractures of the proximal part of the femur with an intramedullary device or an extramedullary device. A prospective, randomized, controlled trial was performed to compare the outcome of treatment of these unstable fractures of the proximal part of the femur with either a sliding hip screw or a long gamma nail. METHODS: Two hundred and ten patients presenting with an AO/OTA 31-A2 fracture of the proximal part of the femur were randomized, at the time of admission, to fixation with use of either a long gamma nail or a sliding hip screw. The primary outcome measure was reoperation within the first postoperative year. Secondary measures included mortality, length of hospital stay, transfusion rate, change in mobility and residence, and quality of life as measured with the EuroQol 5D outcome score. RESULTS: There was no significant difference between the reoperation rates for the two groups. In total, five patients (three from the long-gamma-nail group and two from the sliding-hip-screw group) underwent revision surgery because of cut-out. Tip-apex distance was found to correlate with the implant cut-out rate. There was no significant difference between the two groups in terms of the EuroQol 5D outcome scores, the mortality rates after correction for the mini-mental score, or any of the secondary outcome measures. CONCLUSIONS: When compared with the long gamma nail, the sliding hip screw should remain the gold standard for the treatment of AO/OTA 31-A2 fractures of the proximal part of the femur because it is associated with similar outcomes with less expense.

Complications associated with the use of a titanium tibial nail.

Intramedullary nailing is the treatment of choice for unstable or displaced tibial fractures. Titanium nails have been advocated for their improved biocompatibility and biomechanical properties but concerns are held about increased complications. We present results of 225 tibial fractures in 221 patients (90% follow-up) treated with the ACE titanium tibial nail (DePuy International Limited, Leeds, UK) inserted between 1995 and 2003 in one hospital department, which show no increased complications compared with the published literature. Eighty-two percent of the patients were male with a median age of 33 years. The mechanism of injury was RTA (52%), Sport (22%) and other (26%). Forty-one percent of the fractures were open. The general complication rate represents the published literature whereas only 32% patients developed knee pain compared with the 40-57% previously reported. Median union time was unaffected by open injury, reaming or age. Ninety (43.3%) patients required re-operation of which 23 (11%) had a second re-operation. In total 43 (20.7%) nails were removed, without any complication as previously reported for this nail.

Letters and notes in orthopaedic surgery.

INTRODUCTION: Accurate written communication is essential in orthopaedic surgery. Incomplete and poorly structured letters can lead to poor knowledge of a patient's diagnosis. MATERIALS AND METHODS: Structured and traditional letter formats were compared for speed of reading and preference by general practitioners (GPs), consultants, registrars and out-patient nursing staff. In addition, out-patient clinic letters and notes were analysed and compared for speed of reading and ease of assimilating information and content. RESULTS: There was overwhelming preference for the structured letter format. This style of letter could be read significantly more quickly with information better assimilated and relevant data included more frequently. However, only 26% of letters generated contained a complete set of information sought by GPs and hospital staff. CONCLUSIONS: Structured letters are better in orthopaedics because it is easier to access the contents. The structured format disciplines medical staff to address essential information. Even with a structured format the majority of letters omitted essential information. Training in letter writing is necessary. A structured letter format next to dictating machines might improve the quality of letters generated.

Dermal traction on the Ilizarov frame.

We report a technique of skin traction, which harnesses the biological and mechanical properties of skin. We have used this technique in open fractures to close or reduce the size of the wound, thereby avoiding the use of split skin grafts or free flaps and their resultant additional morbidity. This report summarises our early experience with this technique in seven patients. We describe the technique and the results so far.

Fine wire frame-assisted intramedullary nailing of the tibia.

Intramedullary nailing is accepted as the technique of choice for treatment of unstable tibial diaphyseal fractures. Indirect closed reduction must first be obtained to allow passage of the guide wire and reamers. We describe the use of a simple frame that allows precise reduction, control of rotation and easy imaging access, without increasing operating or screening time.
