Complex Regional Pain Syndrome (CRPS) is regarded as an uncommon clinical complication to orthopaedic surgery. Few have looked into its prevalence in foot and ankle surgery. This is a retrospective cohort study of all patients undergoing foot and ankle surgery, operated on by the foot and ankle team in our department in 2009. The objectives of this study was to determine the prevalence CRPS in these patients post-operatively and to examine the associated factors. 17 patients from 390 (4.4%) were identified as meeting the IASP (International Association for the Study of Pain) criteria for the diagnosis of CRPS. Of these, the majority were female (n = 14, 82.4%) and the average age was 47.2 (SD 9.7). All were elective patients. The majority involved operating on the forefoot (n = 9, 52.9%), followed by the hindfoot and ankle (3 cases each, 17.6%). Most of these patients had new onset CRPS (n = 12, 70.6%), with no previous history of the condition. 3 patients (17.6%) had documented nerve damage and therefore suffered from CRPS Type 2. Blood results were available for 14 (82.4%) patients at a minimum of 3 months post-operatively, and none had elevated inflammatory markers. 5 of the patients (29.4%) were smokers and 8 (47.1%) had a pre-existing diagnosis of anxiety or depression. At present, based on our findings, we recommend that middle-aged women, with a history of anxiety or depression, undergoing elective foot surgery be specifically counselled on the risk of developing CRPS at consenting. We recommend similar studies to be undertaken in other West of Scotland orthopaedic units

Our knowledge of primary bone marrow edema (BME) of the knee is still limited. A major contributing factor is that it shares several radiological findings with a number of vascular, traumatic, and inflammatory conditions having different histopathological features and etiologies. BME can be primary or secondary. The most commonly associated conditions are osteonecrosis, osteochondritis dissecans, complex regional pain syndrome, mechanical strain such as bone contusion/bruising, micro-fracture, stress fracture, osteoarthritis, and tumor. The etiology and pathogenesis of primary BME are unclear. Conservative treatment includes analgesics, non-steroidal anti-inflammatory drugs, weight-bearing limitations, physiotherapy, pulsed electromagnetic fields, prostacyclin, and bisphosphonates. Surgical treatment, with simple perforation, fragment stabilization, combined scraping and perforation, and eventually osteochondral or chondrocyte transplant, is reserved for the late stages. This retrospective study of a cohort of patients with primary BME of the knee was undertaken to describe their clinical and demographic characteristics, identify possible risk factors, and assess treatment outcomes. We reviewed the records of 48 patients with primary BME of the knee diagnosed on MRI by two radiologists and two orthopedists. History, medications, pain type, leisure activities, smoking habits, allergies, and environmental factors were examined. Analysis of patients’ characteristics highlighted that slightly overweight middle-aged female smokers with a sedentary lifestyle are the typical patients with primary BME of the knee. In all patients, the chief symptom was intractable day and night pain (mean value, 8.5/10 on the numerical rating scale) with active as well as passive movement, regardless of BME extent. Half of the patients suffered from thyroid disorders; indeed, the probability of having a thyroid disorder was higher in our patients than in two unselected groups of patients, one referred to our orthopedic center (odds ratio, 18.5) and another suffering from no knee conditions (odds ratio, 9.8). Before pain onset, 56.3% of our cohort had experienced a stressful event (mourning, dismissal from work, concern related to the COVID-19 pandemic). After conservative treatment, despite the clinical improvement and edema resolution on MRI, 93.8% of patients described two new symptoms: a burning sensation in the region of the former edema and a reduced ipsilateral patellar reflex. These data suggest that even though the primary BME did resolve on MRI, the knee did not achieve full healing

The Cobb Stainsby forefoot arthroplasty for claw and hammer toes combines excision arthroplasty (Stainsby) with extensor tendon transfer to the metatarsal head (Cobb). We present a retrospective, three surgeon case series of 218 toes in 128 patients over four years. Clinical notes were reviewed for all patients and 77 could be contacted for a telephone survey. Follow up ranged from 12–82 months. All patients presented with pain and shoe wear problems from dislocated metatarsophalangeal joints either from arthritis, hallux valgus, Freiberg's disease or neurological disorders. Ipsilateral foot procedures were performed simultaneously in 24 (30%) patients. Seventy-two patients (94%) were satisfied, 72 (94%) reported pain relief, 55 (71%) were happy with toe control, 61 (79%) were pleased with cosmesis, 59 (77%) returned to normal footwear and 56 (73%) reported unlimited daily activities. Minor complications occurred in 17 (13%) and 3 (2%) developed complex regional pain syndrome. Four (5%) developed recurrent clawing. The Stainsby procedure permits relocation of the plantar plate under the metatarsal head for cushioned weight-bearing but can create a floppy, unsightly toe. By combining this with the Cobb procedure, our case series demonstrates improved outcomes from either procedure alone with benefits over alternatives such as the Weil's osteotomy.

Background. Volar locking plates have revolutionised the treatment for distal radius fractures. The DVR (Depuy) plate was one of the earliest locking plates which were used and they provided fixed angle fixation. Recently, newer volar locking plates, such as the Aptus (Medartis), have been introduced to the market that allow the placement of independent distal subchondral variable-angle locking screws to better achieve targeted fracture fixation. The aim of our study was to compare the outcomes of DVR and Aptus volar locking plates in the treatment of distal radial fractures. Methods. Details of patients who had undergone open reduction and internal fixation of distal radii from October 2007 to September 2010 were retrieved from theatre records. 60 patients who had undergone stabilisation of distal radius fractures with either DVR (n=30) or Aptus (n=30) plate were included in the study. Results. Mean age of patients undergoing fixation using DVR plate was 56.6 years (n=30) with 22 females and 8 males. Fractures in this group included 20 type 23-C, three type 23-B and seven type 23-A. The patients were followed up for an average of 5.5 months (2-16 months). 3 patients underwent revision of fixation due to malunion (n=1), non-union (n=1) and failure of fixation (n=1). Four patients had reduced movements even after intensive physiotherapy necessitating removal of plate. Mean age of patients undergoing Aptus volar locking plate fixation was 56.38 years (n=30) with 21 females and 9 males. There were 27 type 23-C, two type 23-B and one type 23-A fractures according to AO classification. The patients were followed up for an average of 4.1 months (2-11 months). 2 patients developed complex regional pain syndrome (CRPS) and 1 patient underwent removal of screws due to late penetration of screws into the joint. Conclusion. Complex and unstable fractures of the distal radius can be optimally managed with volar locking plates. Both systems are user friendly. Aptus plates provide an additional advantage of flexibility in implant positioning and enhanced intra-fragmentary fixation compared to the DVR plate. In our study Aptus plates had lower secondary surgical procedures compared to DVR plates
