Background Frozen shoulder has not previously been shown to be associated with infection. The present study set out to confirm the null hypothesis that there is no relationship between infection and frozen shoulder using two modern scientific methods, extended culture and polymerase chain reaction (PCR) for bacterial nucleic acids. Methods A prospective cohort of 10 patients undergoing arthroscopic release for stage II idiopathic frozen shoulder had two biopsies of tissue taken from the affected shoulder joint capsule at the time of surgery, along with control biopsies of subdermal fat. The biopsies and controls were examined with extended culture and PCR for microbial nucleic acid. Results Eight of the 10 patients had positive findings on extended culture in their shoulder capsule and, in six of these, Propionibacterium acnes was present. Conclusions The findings mean that we must reject the null hypothesis that there is no relationship between infection and frozen shoulder. More studies are urgently needed to confirm or refute these findings. If they are confirmed, this could potentially lead to new and effective treatments for this common, painful and disabling condition. Could P. acnes be the Helicobacter of frozen shoulder?

We reviewed 12 patients with primary glenoid dysplasia. Ten were assessed clinically and two from case notes and radiographs. We identified two groups according to the age at onset of symptoms. The first (seven patients) consisted of boys and younger men, all of whom developed symptoms before the age of 40 years. All four children were free from pain, whereas the three adults in this group had varying degrees of this. Four patients had symptoms of instability. The second group consisted of older men (five patients) all of whom had noted the onset of symptoms, in the form of pain and stiffness, after the age of 40 years. All five had radiological evidence of osteoarthritis. Although the four children in our study had minimal symptoms, all eight adults had ongoing shoulder pain and dysfunction, despite a specific rehabilitation programme. Four patients required surgery; one had posterior stabilisation for instability and three arthroplasties of the shoulder for osteoarthritis.

INTRODUCTION Collecting outcome scores in paper form is fraught with difficulty. We have assessed the feasibility of, and patient's attitude towards, entering scores using a touchscreen. PATIENTS AND METHODS A touchscreen was installed in the orthopaedic out-patient clinic. If relevant, patients were asked to complete either an Oswestry Disability Index (ODI) or Oxford Shoulder Score (OSS) using the screen. Patients were given written instructions and their hospital number by the receptionist who had no further input. Scores were completed with two identifiers. A paper questionnaire was used to assess computer experience and attitude towards the touchscreen. RESULTS A total of 1348 patients, average age 50 years, successfully completed a score in the first 12 months. One-third were over 60 years. Overall, 91% correctly entered their hospital number and date of birth, falling to 84% in patients over 70 years. All patients were identifiable. The average time to complete the scores was 4.7 min rising with age. Of 170 patients completing the paper assessment of the touchscreen, one-third had little or no experience of computers and a third were over 60 years. Of patients, 93% were willing to repeat the score using the touchscreen to monitor progress. Two-thirds found it easier to use than expected. Only 10% would prefer a paper score. These results were maintained among patients over 60 years. Only two were unable to complete the score and 80% of those potentially eligible did so. The remainder were called to clinic before the touchscreen was free. CONCLUSIONS Orthopaedic outcome scores can be collected in very large volumes using a touchscreen. Data are then in an immediately usable form. The method is acceptable to patients, independent of age and computer experience. Even in the oldest patients, the accuracy is higher than for paper versions of the score. Combined with operative data, this simple method has the potential to provide a very powerful audit tool indeed.

INTRODUCTION The aim of this prospective study was to assess the immediate and long-term effectiveness of arthroscopic capsular release in a large cohort of patients with a precise and isolated diagnosis of stage II idiopathic frozen shoulder. METHODS All patients underwent a preoperative evaluation. Patients with secondary frozen shoulder and those with concurrent pathology at arthroscopy were excluded. This left 136 patients with a stage II arthroscopically confirmed idiopathic frozen shoulder. At each postoperative attendance, a record was made of pain, function and range of motion. At 12 months, the Oxford shoulder score was calculated, and pain and range of motion were assessed. RESULTS Fifty per cent achieved good pain relief within a week and eighty per cent within six weeks of arthroscopic capsular release. The mean preoperative visual analogue scale pain score was 6.6 and the mean postoperative score was 1.0. The mean time to achieving good pain relief was 16 days following surgery. No patient could sleep through the night prior to surgery while 90% reported having a complete night’s sleep at a mean of 12 days after surgery. The mean postoperative Oxford shoulder score was 38/48 and the mean improvement was 19.2. CONCLUSIONS This large series demonstrates that arthroscopic capsular release is a safe procedure, with rapid improvement in pain and a marked improvement in range of motion.

INTRODUCTION Nearly 1 in 40 of the population seeks medical advice related to a shoulder problem every year. The majority pertain to rotator cuff pathology. Prior to intervention in such patients it is imperative to define whether the tendons are intact or torn. Ultrasonography has become an essential adjunct to clinical assessment in diagnosing rotator cuff tears. This study was designed to investigate if a surgeon using a portable ultrasonography machine in a one-stop shoulder clinic could significantly reduce the time a patient waited from initial outpatient presentation to the end of the treatment episode (be it surgery, injection or conservative management). METHODS A total of 77 patients were allocated to one of two groups: Group A, consisting of 37 patients who were assessed and had ultrasonography as outpatients, and Group B, consisting of 40 patients who were assessed and referred for departmental ultrasonography where appropriate. Three clear outcome groups were defined: those who required surgical repair, those who had irreparable tears and those who declined surgery. RESULTS For all outcomes (surgery, irreparable tears and conservative treatment), the patients in Group A all completed their clinical episodes significantly quicker than those in Group B (pCONCLUSIONS The use of a portable ultrasonography machine by an orthopaedic surgeon can significantly reduce the time to treatment and the financial cost for patients with rotator cuff tears.

We describe an apparently unreported finding during hip operations: a tear at the insertion of gluteus medius and gluteus minimus. This defect may well be known to many surgeons with experience of hip replacement and hemiarthroplasty for fractures of the neck of the femur, but a Medline search has failed to find a previous description. We made a prospective study of 50 consecutive patients with fractures of the neck of the femur to quantify the incidence of this condition: 11 (22%) had such a tear.

A series of 100 roller skating injuries is presented. Roller skating injuries have been occurring at a higher rate than the previously reported skateboarding epidemic of 1977. The severity of injury has been lower, 32% fractures and dislocations occurring whilst roller skating, compared to 60% whilst skateboarding. In particular a striking reduction is seen in ankle fractures. Fifty questionnaires detailing method of injury were analysed.

This study set out to quantify the information which is given to surgical patients. It also set out to discover what information patients felt was important. The group studied were all patients who had recently undergone transurethral resection of the prostate. Eighty two per cent would have liked to have been given the information leaflet to read before their operation. The piece of information most patients wanted was the estimated length of stay in hospital (83%). Patients under seventy years old wanted to discuss the effect of the operation on their sex lives (79%). It is concluded that information leaflets are appreciated by patients and should be more widely used.

Op-Site sutureless skin closures were compared with continuous nylon sutures in a controlled trial involving 55 major orthopaedic procedures. Three major problems were identified in the sutureless skin closure group--safety, accuracy of skin edge apposition, and ease of use. Op-Site sutureless skin closures were found to have a better cosmetic result, were more comfortable and had a lower rate of wound inflammation. Op-Site skin closures are a useful adjunct to sutures but will not replace them.
