Management of sports injuries of the foot and ankle: An update.

Injuries to the foot in athletes are often subtle and can lead to a substantial loss of function if not diagnosed and treated appropriately. For these injuries in general, even after a diagnosis is made, treatment options are controversial and become even more so in high level athletes where limiting the time away from training and competition is a significant consideration. In this review, we cover some of the common and important sporting injuries affecting the foot including updates on their management and outcomes.

Management of sports injuries of the foot and ankle: an update.

Sporting injuries around the ankle vary from simple sprains that will resolve spontaneously within a few days to severe injuries which may never fully recover and may threaten the career of a professional athlete. Some of these injuries can be easily overlooked altogether or misdiagnosed with potentially devastating effects on future performance. In this review article, we cover some of the common and important sporting injuries involving the ankle including updates on their management and outcomes.

The anatomical footprint of the Achilles tendon: a cadaveric study.

We dissected 12 fresh-frozen leg specimens to identify the insertional footprint of each fascicle of the Achilles tendon on the calcaneum in relation to their corresponding muscles. A further ten embalmed specimens were examined to confirm an observation on the retrocalcaneal bursa. The superficial part of the insertion of the Achilles tendon is represented by fascicles from the medial head of the gastrocnemius muscle, which is inserted over the entire width of the inferior facet of the calcaneal tuberosity. In three specimens this insertion was in continuity with the plantar fascia in the form of periosteum. The deep part of the insertion of the Achilles tendon is made of fascicles from the soleus tendon, which insert on the medial aspect of the middle facet of the calcaneal tuberosity, while the fascicles of the lateral head of the gastrocnemius tendon insert on the lateral aspect of the middle facet of the calcaneal tuberosity. A bicameral retrocalcaneal bursa was present in 15 of the 22 examined specimens. This new observation and description of the insertional footprint of the Achilles tendon and the retrocalcaneal bursa may allow a better understanding of the function of each muscular part of the gastrosoleus complex. This may have clinical relevance in the treatment of Achilles tendinopathies.

Entrapment of the sciatic nerve following closed reduction of a dislocated revision total hip replacement.

Injury to the sciatic nerve following closed manipulation of a dislocated total hip replacement is rare. We present such a case in an elderly patient with partial recovery following exploration and release of the nerve.

Correcting genu varum and genu valgum in children by guided growth: temporary hemiepiphysiodesis using tension band plates.

A total of 25 children (37 legs and 51 segments) with coronal plane deformities around the knee were treated with the extraperiosteal application of a flexible two-hole plate and screws. The mean age was 11.6 years (5.5 to 14.9), the median angle of deformity treated was 8.3 degrees and mean time for correction was 16.1 months (7 to 37.3). There was a mean rate of correction of 0.7 degrees per month in the femur (0.3 degrees to 1.5 degrees ), 0.5 degrees per month in the tibia (0.1 degrees to 0.9 degrees ) and 1.2 degrees per month (0.1 degrees to 2.2 degrees ) if femur and tibia were treated concurrently. Correction was faster if the child was under 10 years of age (p = 0.05). The patients were reviewed between six and 32 months after plate removal. One child had a rebound deformity but no permanent physeal tethers were encountered. The guided growth technique, as performed using a flexible titanium plate, is simple and safe for treating periarticular deformities of the leg.

Use of a patient consultation questionnaire and weighted numerical scoring system for the prediction of colorectal cancer and other colorectal pathology in symptomatic patients: a prospective cohort validation study of a Welsh population.

OBJECTIVE: There is currently no system in widespread use that accurately prioritizes colorectal referrals in symptomatic patients with an acceptable degree of sensitivity and specificity. We have validated a weighted numerical scoring system for the prioritization of such colorectal referrals in an attempt to rectify this, with detection of colorectal cancer (CRC) the primary outcome. METHOD: We conducted a prospective study of symptomatic patients referred by primary care to the colorectal service in a district general hospital. A computer-generated weighted numerical score (WNS) was derived from the primary symptoms and symptom combinations. Patients underwent colorectal investigations and a final diagnosis was established. Sensitivity, specificity and accuracy of CRC detection as determined by the WNS, Department of Health (DOH) and National Institute for Health and Clinical Excellence guidelines was determined. Primary Care compliance with guidelines was analysed. RESULTS: A definitive diagnosis was established in 3457 patients. One hundred and eighty-six (5.4%) had CRC. The mean score for the cancer patients (76.9, 95%CI 72-81) was significantly higher than that of non-cancer patients (52, 95%CI 52-53) P < 0.001. Receiver Operator Curve analysis demonstrates a high discriminatory power for the Patient Consultation Questionnaire (PCQ) with an area under curve of 0.76. Compliance by primary care with the nationally recommended referral guidelines was poor with only 55% and 58% compliance with DOH and National Institute for Clinical Excellence referral guidelines for suspected cancer respectively. CONCLUSION: The PCQ and the WNS is an efficient, objective system that allows the accurate prioritization of colorectal referrals with a high sensitivity for cancer and other serious colorectal pathologies.

Proximal femoral nail failures in extracapsular fractures of the hip.

PURPOSE: To review patients with proximal femoral nails (PFNs) in our hospital that developed complications and needed revision. METHODS: Between January 2000 and June 2006, records of 216 patients with PFN fixations for traumatic extracapsular trochanteric fractures (n=160), pathological fractures (n=23), and as a prophylactic measure for metastasis (n=33) were retrospectively reviewed. The injury mechanism, reduction technique and quality, and time to and cause of implant failure were recorded. RESULTS: 12 PFNs failed: 8 in the trauma group, 3 in the pathological group, and one in the prophylactic nailing group. Two PFNs broke at the proximal lag screw level at a later stage secondary to non-union of the pathological fractures. One broke at the level of the distal locking screw at an early stage, as the locking holes were too close to the fracture. CONCLUSION: Poorly reduced fractures tend to fail early, whereas late failures are due to non-union. Good reduction with minimal dissection, the use of appropriate nail length, and proper positioning of the nail and screws are necessary to avoid failure or revision.

Traumatic transepiphyseal separation of the upper femoral epiphysis following seizures in two children with cerebral palsy.

Transepiphyseal separation of the neck of the femur following grand mal seizures is described in two children with cerebral palsy. Closed reduction and percutaneous fixation was followed by a period in a hip spica. Although the incidence of avascular necrosis of the femoral head is high following such injury, this has not occurred in these patients at a follow-up of 18 months.

Rhys-davies exsanguinator: a haven for bacteria.

Serial swabs were taken from the inner and outer surfaces of a new Rhys-Davies exsanguinator before and after use on the limbs of patients to exsanguinate limbs prior to tourniquet inflation and surgery. Both surfaces of the exsanguinator showed increasing levels of contamination with bacterial colonisation with use starting from the first use. The organisms grown included potentially harmful bacteria such as Pseudomonas sp. The Rhys-Davies exsanguinator can harbour potentially harmful organisms and, thus, may raise the risk of infection transmission between patients when used without cleaning between uses. Methods of effective cleaning of the exsanguinator between uses are discussed.

The risk of cross-infection when marking surgical patients prior to surgery - review of two types of marking pens.

INTRODUCTION: Two types of marker pens were compared to find whether they produced different risks of infection transmission over different time intervals. PATIENTS AND METHODS: Twenty-four patients were marked according to the type of surgery: each had a set of new dry white-board marker (DWM) and a permanent marker (PM) pen. Once used, their tips were used to inoculate blood agar plates at different time intervals. RESULTS: At 0 min, 96% of the DWM pens and 29% of the PM pens were positive of growth. At 3 and 10 min, all of the DWM pens remained positive. The rate dropped to 16.67% in 3 min down to none at 10 min for the PM pens. CONCLUSIONS: DWM pens carry a significant risk of transmitting infection between patients. It is recommended that they are not used in marking. PM pens should not be used between patients in less than a 10-min interval.

Prediction of colorectal cancer by a patient consultation questionnaire and scoring system: a prospective study.

BACKGROUND: Current NHS guidelines for referral of patients with colorectal symptoms classify many as high risk but fail to identify a significant number of cancers in the low-risk group. We describe a practical scoring method to predict colorectal cancers. METHODS: From October, 1999, 2268 patients with distal colonic symptoms, referred by general practitioners, completed a patient consultation questionnaire linked to a computerised record. Referrals were prioritised with a malignancy risk score by a senior colorectal surgeon separately from the general practitioner's letter and from the questionnaire. A weighted numerical score was derived from weighting of primary symptoms and symptom complexes and was calculated automatically when the questionnaire data were entered into the computer program. Analysis by receiver-operating characteristics assessed the scoring systems. Sensitivities and specificities of scoring systems were compared with McNemar's test. FINDINGS: Of the 2268 patients, 95 had colorectal cancer. The average weighted numerical score was significantly higher for patients with cancer than for non-cancer patients (mean 76.5 [95% CI 72.2-80.9] vs 44.5 [43.6-45.4]; p<0.0001). At similar cancer detection rates, the malignancy risk score derived from the patient consultation questionnaire and the weighted numerical score graded lower proportions of referrals as urgent than did the current NHS guidelines (43.1% and 39.8% vs 49.8%; p<0.0001). INTERPRETATION: The patient consultation questionnaire depends on history alone and is easily reproducible. In conjunction with the weighted numerical score, which removes operator bias, it can be used as an accurate system for prediction of symptomatic colorectal cancer.
