Background. Implants based on the polyetheretherketon (PEEK) polymer have been developed in the last decade as an alternative to conventional metallic devices. PEEK devices may provide several advantages over the use of conventional orthopedic materials, including the lack of metal allergies, radiolucency, low artifacts on magnetic resonance imaging scans and the possibility of tailoring mechanical properties. The purpose of this study was to evaluate the clinical results at mean 24-month follow-up using a new plate made of carbon-fiber-reinforced polyetheretherketon (CFR-PEEK) for the treatment of distal radius fractures. Materials and methods. We performed a prospective study including all patients who were treated for unstable distal radius fracture with a CFR-PEEK volar fixed angle plate. We included 70 consecutive fractures of AO types B and C that remained displaced after an initial attempt at reduction. The fractures were classified according to the AO classification: 35 fractures were type C1, 13 were type C2, 6 were type C3, 5 were type B1 and 11 were type B2. Results. All fractures healed, and radiographic union was observed at an average of 6 weeks. The final Disabilities of Arm, Shoulder and Hand score was 5.2 points. The average grip strength, expressed as a percentage of the contralateral limb, was 94 %. Three cases of hardware breakage were reported. Two cases were due to intraoperative plate rupture caused by the attempt to achieve the reduction of the fracture in 1 case and while inserting a distal screw in the other case. In the last case hardware breakage was caused by a fall on the injuried arm 1 week after surgery. No cases of loss of the surgically achieved fracture reduction were documented. Hardware removal was performed in 3 cases, for the occurrence of extensor tenosynovitis in 2 patients and tenosynovitis of flexor pollicis longus in 1 case. Conclusion. The major advantage of CFR-PEEK plate is its radiolucency. This characteristic allows direct visualization of osseous callus formation, allowing monitoring of the healing of the fracture, thereby improving clinical assessment and accuracy. Therefore, specific indications for this new radiolucent plate can be represented by fractures with significant metaphyseal comminution and in cases of nascent malunion where a distal radius osteotomy with bone grafting is usually performed to correct the wrong angle. At early follow-up this device showed good clinical results and allowed maintenance of reduction in complex, AO fractures. The occurrence of tendon complications related to this implant was similar to that reported in literature for the other new-generation plates. However, attention should be payed when stressing the plate to achieve the desired fracture reduction to avoid hardware failure

Percutaneous A1 pulley release is being increasingly used as an alternative to open surgical release and injection of local steroids for the treatment of the trigger digit. We treated 43 patients, average age 57 years (range12-78). All trigger digits were grade III-IV (Quinnell classification). A mean duration of pre-operative symptoms was 7.3 months (range 2-13 months). A percutaneous release was performed with a 19-gauge hypodermic needle under local anaesthesia in the outpatient setting. All patients were evaluated with respect to clinical resolution of symptoms and general satisfaction. We report a 97% successful release and only one case of incomplete release. A result in terms of abolishing triggering was immediate and patient acceptance was excellent. By two weeks, all the patients had no pain at the operative site. After a mean follow-up of 30.2 months (range12-50), there had been no recurrences. There were no digital nerve injuries, flexor tendon injuries, and infections. The percutaneous release is a safe and effective technique, which provides significant cost savings. The time from onset of symptoms and grading prognostically is significant and affects the treatment outcome. We recommend the percutaneous technique for typical cases of trigger finger with a palpable nodule and reproducible mechanical triggering. This technique can be the treatment of choice for the established trigger finger (grade III and IV) with symptoms of more than few months' duration. The open technique is reserved for complicated cases such as florid tenosynovitis, locked digit, failed percutaneous release or those involving the thumb

This study reports the results of open reduction and internal fixation of 26 unstable, intra-articular, dorsally displaced fractures of the distal radius using a bio absorbable dorsal distal radius (Reunite) plate and calcium phosphate (Biobon) bone substitute. The bio absorbable plate has the advantages of being low profile, easily contourable due to temporary malleability and is angularly stable. It retains its strength for 6 to 8 weeks and undergoes complete mass loss within one year, thereby allowing gradual load transfer to the healing bone. In the majority of cases, this plate produces functional results comparable with metal plates. The Gartland and Werley score was excellent or good in 21 patients. The most important advantage over metal plates is in eliminating the need to remove the plate and hence the need for a second operation if implant related extensor tenosynovitis occurs. Inflammatory tissue reaction to the degradation products of the plate is a potential concern, although the co-polymer ratio used in this plate appears to have reduced the severity of this reaction, which was seen in two patients in this series. The reduction was lost in five patients with severe dorsal comminution. For such fractures, the plate did not retain its strength for long enough to allow adequate healing for satisfactory load transfer. Following this experience, we do not recommend this plating system for fractures with a metaphyseal gap of greater than 7 mm following reduction. For fractures that cannot be treated by closed means but where the metaphyseal gap following reduction is less than 7 mm, this plate provides all the theoretical advantages. Further developments allowing the plate to retain its strength for longer while maintaining the low incidence of inflammatory reactions will make it more universally applicable for the treatment of a greater spectrum of unstable distal radius fractures

Aims

COVID-19 remains the major focus of healthcare provision. Managing orthopaedic emergencies effectively, while at the same time protecting patients and staff, remains a challenge. We explore how the UK lockdown affected the rate, distribution, and type of orthopaedic emergency department (ED) presentations, using the same period in 2019 as reference. This article discusses considerations for the ED and trauma wards to help to maintain the safety of patients and healthcare providers with an emphasis on more remote geography.

Methods

The study was conducted from 23 March 2020 to 5 May 2020 during the full lockdown period (2020 group) and compared to the same time frame in 2019 (2019 group). Included are all patients who attended the ED at Raigmore Hospital during this period from both the local area and tertiary referral from throughout the UK Highlands. Data was collected and analyzed through the ED Information System (EDIS) as well as ward and theatre records.

Aims

To describe the incidence of adverse clinical outcomes related to COVID-19 infection following corticosteroid injections (CSI) during the COVID-19 pandemic. To describe the incidence of positive SARS-CoV-2 reverse transcriptase polymerase chain reaction (RT-PCR) testing, positive SARS-COV2 IgG antibody testing or positive imaging findings following CSI at our institution during the COVID-19 pandemic.

Methods

A retrospective observational study was undertaken of consecutive patients who had CSI in our local hospitals between 1 February and 30June 2020. Electronic patient medical records (EPR) and radiology information system (RIS) database were reviewed. SARS-CoV-2 RT-PCR testing, SARS-COV2 IgG antibody testing, radiological investigations, patient management, and clinical outcomes were recorded. Lung findings were categorized according to the British Society of Thoracic Imaging (BSTI) guidelines. Reference was made to the incidence of lab-confirmed COVID-19 cases in our region.

Non-tuberculous mycobacterial (NTM) infection of the musculoskeletal tissue is a rare disease. An early and accurate diagnosis is often difficult because of the indolent clinical course and difficulty of isolating pathogens. Our goal was to determine the clinical features of musculoskeletal NTM infection and to present the treatment outcomes. A total of 29 patients (nine females, 20 males between 34 and 85 years old, mean age 61.7 years; 34 to 85) with NTM infection of the musculoskeletal system between 1998 to 2011 were identified and their treatment retrospectively analysed. Microbiological studies demonstrated NTM in 29 patients: the isolates were Mycobacterium intracellulare in six patients, M. fortuitum in three, M. abscessus in two and M. marinum in one. In the remaining patients we failed to identify the species. The involved sites were the hand/wrist in nine patients the knee in five patients, spine in four patients, foot in two patients, elbow in two patients, shoulder in one, ankle in two patients, leg in three patients and multiple in one patient. The mean interval between the appearance of symptoms and diagnosis was 20.8 months (1.5 to 180). All patients underwent surgical treatment and antimicrobial medication according to our protocol for chronic musculoskeletal infection: 20 patients had NTM-specific medication and nine had conventional antimicrobial therapy. At the final follow-up 22 patients were cured, three failed to respond to treatment and four were lost to follow-up. Identifying these diseases due the initial non-specific presentation can be difficult. Treatment consists of surgical intervention and adequate antimicrobial therapy, which can result in satisfactory outcomes.

We report the results of six trauma and orthopaedic projects to Kenya in the last three years. The aims are to deliver both a trauma service and teaching within two hospitals; one a district hospital near Mount Kenya in Nanyuki, the other the largest public hospital in Kenya in Mombasa. The Kenya Orthopaedic Project team consists of a wide range of multidisciplinary professionals that allows the experience to be shared across those specialties. A follow-up clinic is held three months after each mission to review the patients. To our knowledge there are no reported outcomes in the literature for similar projects.

A total of 211 operations have been performed and 400 patients seen during the projects. Most cases were fractures of the lower limb; we have been able to follow up 163 patients (77%) who underwent surgical treatment. We reflect on the results so far and discuss potential improvements for future missions.

We examined the usefulness of neutrophil CD64 expression in detecting local musculoskeletal infection and the impact of antibiotics on its expression. Of 141 patients suspected of musculoskeletal infection, 46 were confirmed by microbiological culture to be infected and 95 had infection excluded. The median CD64 count of patients with localised infection was 2230 molecules per cell (interquartile range (IQR) 918 to 4592) and that of the patients without infection was 937 molecules per cell (IQR 648 to 1309) (p < 0.001). The level of CD64 correlated with the CRP level in patients with infection, but not in those without infection (r = 0.59, p < 0.01). Receiver operator characteristic curve analysis revealed that CD64 was a good predictor of local infection. When the patients were subdivided into two groups based on the administration of antibiotics at the time of CD64 sampling, the sensitivity for detecting infection was better in those who had not received antibiotics.

These results suggest that measurement of CD64 expression is a useful marker for local musculoskeletal infection.
