Total femoral spanning for distal femur "fragility" fractures utilising nail-plate fixation "short-term experience of a district general hospital".

PURPOSE: Our primary objective was to investigate the time to radiological union following linked nail-plate fixation of distal femur "fragility" fractures. Secondary objectives were to evaluate all-cause reoperations, 90-day mortality, rate of blood transfusion and the impact on quality of life. METHODS: In this retrospective study of all adults (≥ 65 years) with native or periprosthetic distal femur fragility fractures, underwent a linked nail-plate fixation, data were retrieved on fracture classifications, clinical frailty score, blood transfusion, length of hospital stay, 90-day mortality, time to radiological union, overall complication rates and EuroQoL-5D. RESULTS: In total, 18 out of 23 patients completed sequential follow-up. Radiological union was observed in 14 patients (median 143 days; range 42-414). Three patients underwent reoperations. There were no implant failures or a subsequent periprosthetic fractures. Ninety-day mortality was 17.4%. Eighteen patients required blood transfusion. The QoL was significantly lower after index surgery (0.875 vs. 0.684; p < 0.01). CONCLUSION: Based on our observation, with short-term follow-up, the linked nail-plate yields optimal stability to allow immediate weight bearing, in a cohort with moderate frailty. It is reproducible, with variable radiological union rates. The concept of "total femoral spanning" reduces the risk of subsequent periprosthetic fractures. The additional intervention has increased the rates of allogenic blood transfusion. There is significant impact on overall QoL, with almost 50% being more dependent in self-care.

Improvements in networking processes for hip or knee revision arthroplasty: a silver lining of the COVID-19 pandemic.

BACKGROUND: Improvements in outcomes following hip and knee revision arthroplasties have been demonstrated following the introduction of specialised orthopaedic services in the form of 'hub and spoke' networking models. In light of the COVID-19 pandemic, these networks have undergone some inevitable adaptations. We investigated the impact of recent adaptations on the performance of our regional revision arthroplasty network. METHODS: A retrospective review of all referrals that were discussed at our regional revision arthroplasty meeting, over 2 separate phases, was undertaken. Phase 1 included data between March 2018 and April 2019, representing an interval prior to COVID-19 pandemic. Phase-2 included data between September 2020 and March 2021 (during COVID-19 pandemic). Data were collected from East Midland South Orthopaedic Network (EMSSON) database and included data relating to indication and time to revision surgery, surgeon's proposal plan, network proposal plan, and executed definitive plan. We compared and analysed network performance between 2 phases. RESULTS: In phase 1, 99 cases were discussed in EMSSON meetings, equating to 35.7% of the region's revision arthroplasty volume, according to the National Joint Registry (NJR) records. Plan alterations were recommended in 48/99 cases (48.5%), of which 41/48 (85.4%) were adhered to. Phase 2 included 98 discussed cases, equating to 81.6% of the region's revision arthroplasty volume. Plan alterations were recommended in 20/98 cases (20.4%), all of which were adhered to (100%). Adherence to recommended adaptations showed significant improvement (p < 0.03). CONCLUSIONS: Based upon our observations, a greater volume and proportion of revision arthroplasty cases are now being discussed. Adherence to MDT recommendations has significantly improved following the described adaptations. The number of recommended adaptations to management plans have decreased, indicating an educational value of the network.Overall, these findings demonstrate a trend towards NHS England's target of 100% of revision arthroplasty cases undergoing MDT discussion.

The onset, progress and factors influencing degenerative arthritis of the wrist following scaphoid fracture non-union.

BACKGROUND/AIMS: Scaphoid non-union causes osteoarthritis but factors associated are poorly understood. We investigated the rate of osteoarthritis after scaphoid fracture non-union, and if duration and fracture location influenced arthritis and its severity. METHODS: This retrospective cross-sectional observational study of 278 consecutive cases with scaphoid fracture non-union retrieved data on demographics, non-union duration, fracture location, dorsal intercalated segment instability (DISI), severity and distribution of wrist arthritis. Patient Evaluation Measure (PEM) and Quality of Life assessed impact on patients. Regression models investigated prediction of osteoarthritis by different variables. Time-to-event analysis investigated osteoarthritis evolution. Missing (MAR) data for the PEM and QoL was imputed and analysed. RESULTS: 278 patients, 246 males, aged 27.9 years (range 11 to 78 years), with a scaphoid fracture non-union confirmed on computed tomography (CT) scans (243) and plain radiographs (35) were reviewed. The interval between injury and imaging was 3.3 years (SD 5.9 years; range 0.1-45). The fracture was proximal to the ridge in 162, distal to the ridge in 83 and in the proximal 20% in 33. DISI (RLA ≥ 10°) occurred in 93.5% (260/278). Osteoarthritis was identified in 62.2% (173/278), and we classified a SNAC pattern in 93.6% (162/173). Of these, 100 (61.7%) had SNAC 1, 22 (13.6%) SNAC 2, 17 (10.5%) SNAC 3, and 23 (14.2%) SNAC 4. The mean duration in years for SNAC 1, 2, 3 and 4 were 2.5, 6.0, 8.2, and 11.3 years respectively. In fractures proximal to the ridge, 50% had arthritis in 2.2 years. Whereas in proximal pole, and distal to the ridge, 50% developed in 3.8 and 6.6 years, respectively. The PEM score was 42.8% (SD 18.9%) in those without arthritis and 48.8% (SD 21.5%) in those with arthritis. The mean QoL was 0.838 in patients without SNAC and 0.792 with SNAC. CONCLUSION: Scaphoid fracture non-union caused early carpal collapse, majority had osteoarthritis usually observed within a year following injury and occurred earliest in proximal waist fractures. Distribution of osteoarthritis (SNAC stage) may not always follow a distinctive pattern, as previously described.

Radiological and Long-Term Functional Outcomes of Displaced Distal Clavicle Fractures.

OBJECTIVES: To investigate radiological and long-term functional outcomes in modified Neer 2a, 2b, and 5 distal clavicle fractures. DESIGN: Retrospective cohort study. SETTING: A single university teaching hospital. PATIENTS/PARTICIPANTS: One hundred fifteen patients sustaining displaced distal clavicle fractures between January 01, 2010 and December 12, 2017. INTERVENTION: Operative versus nonoperative management. MAIN OUTCOME MEASUREMENTS: Radiographs were reviewed for fracture management and union. A customised questionnaire consisting of QuickDASH (Disabilities of the Arm, Shoulder and Hand), work, sports/performing arts, global satisfaction, and complication modules was used to determine functional outcome. RESULTS: One hundred fifteen patients were included [mean age of 49 (18-89) years]. Thirty-three (29%) underwent early fixation (<6 weeks from injury) and were younger (37 vs. 53 years, P < 0.0001). Radiographs were available for 96 patients. Nonunion rate was 55% (53/96), and majority had undergone initial nonoperative management (49 vs. 4, P < 0.00001). Eleven patients with symptomatic nonunion were deemed appropriate for delayed fixation with all cases uniting. Of the operatively managed patients, 27% (12/44) underwent metalwork removal. There were no differences in functional outcome between operative versus nonoperative and union versus nonunion patient groups at a mean follow-up of 79 months ( P > 0.05). CONCLUSION: Functional outcome and patient satisfaction at long-term follow-up were similar regardless of operative fixation or radiological union. Nonunion in displaced distal clavicle fractures seemed to cause minimal functional deficit in most elderly sedentary individuals, or the outcome measures were not sensitive enough to capture these differences. An individualized approach should be adopted, with less active, comorbid, and elderly patients counseled regarding the minimal functional improvement of surgery and risk of reoperation. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

The importance of the early appropriate management of foot and ankle soft tissue sarcomas - experiences of a regional sarcoma service.

INTRODUCTION: Soft tissue sarcomas (STS) are a group of rare malignant tumours that can occur at almost any anatomical location in patients of any age, which often present to health care professional working outside a recognised sarcoma service. A review of foot and ankle STSs was conducted, reporting on patient and tumour characteristics, and patient outcome following surgery performed within and outside our sarcoma service. PATIENTS AND METHODS: A retrospective review of all foot and ankle STSs managed by our sarcoma service over a 14 year period was performed. Patient demographics, tumour characteristics, management and patient outcomes including recurrence rates and survival were analysed. RESULTS: Twenty-six patients were analysed (16F:10M) with a mean age of 57.7 years (range 17-87). The mean follow-up was 6.3 years (range 1-16). Sixteen tumours involved the foot, nine the ankle, and one spanned the foot and ankle. Mean tumour size was 4.3 cm (range 0.8-15), although 61% of cases were smaller than 4 cm, and almost one third of cases smaller than 1 cm. Seven of 26 (27%) cases were diagnosed after an unplanned excision performed by non sarcoma surgeons. These patients were more likely to undergo an incomplete tumour excision (p < 0.001), suffer local recurrence (p = 0.001), and eventually undergo a secondary amputation (p = 0.034) than those patients managed exclusively by a sarcoma service. Overall, 12 (46%) patients died of their disease during follow up, equating to a five-year survival rate of 69%. CONCLUSION: Our data shows that unplanned excisions continue to be performed on foot and ankle STSs, and that these have detrimental effects on patients. Despite this, our results also show that these complex patients can be managed successfully when referred appropriately to a sarcoma service, prior to any surgical treatment. This highlights the importance of vigilance amongst all health care professionals managing any foot or ankle lumps, regardless of their size.

Common tendinopathies around the elbow; what does current evidence say?

Tendinopathies are common causes of pain around the elbow resulting in significant functional impairment in athletes or the working-age population. Patients complain of a gradual onset pain with or without any specific trauma. Tissue histology shows chronic fibroblast and vascular proliferation, with a disorganized collagen pattern and absence of inflammatory mediators. Currently, numerous treatment options are described, but many of these are only supported by a heterogenous evidence base. Thus, management guidelines are difficult to define. Surgery is mostly indicated in selected cases that have failed non-operative management. This article reviews the pathophysiology and natural history of lateral and medial elbow tendinopathies, as well as distal biceps and triceps tendinopathies, and their current treatment options.

Audit changes practice-a simple education intervention can lead to better outcome in ankle fracture surgery.

BACKGROUND: Unstable ankle fractures are common, and majority requires open reduction and internal fixation (ORIF). There is emerging evidence that the rate of malreduction has remained high despite advances in surgical techniques and implants. Malreduced ankle is a prominent cause of post-traumatic ankle arthritis leading to poor patient reported outcome. The aim of this study was to investigate the quality of anatomical reduction and surgical fixation of ankle fractures and the impact of simple education intervention on the quality of reduction of these fractures. METHODOLOGY: An audit cycle was completed in two phases; retrospective review (phase 1) of 114 cases operated prior to an education intervention using infographic posters and then a prospective (phase 2) review of 96 consecutive cases operated after the education intervention. Data including age, fracture morphology, time to surgery, and the quality of reduction were assessed. The quality of anatomical reduction was evaluated using radiological parameters described by Pettrone. Paediatric, Weber A, pathological and open fractures were excluded. Education interventions included regional teaching and dissemination of infographic posters. Mann- Whitney U test and Chi-squared test were used to compare continuous and categorical data between phase 1 and 2 respectively. P value < 0.05 was considered significant. RESULTS: Phase one cohort showed malreduced fixation in 25% of cases. Inadequate restoration of fibular length was the most common type of malreduction. After implementation of education intervention, malreduction rate reduced to 9.4% in phase 2 (p = 0.015). There were no significant differences between age, gender, and time to surgery between phase one and two. CONCLUSION: This study demonstrates that simple education intervention can lead to better understanding of fixation and decrease the rate of malreduction of these fractures. We recommend that using Pettrone's radiological criteria in correction of corresponding anatomy of ankle fracture is a useful tool to avoid malreduction.

Cat bite: an injury not to underestimate.

Domestic cat bites are common and are often treated by simple wound care with good outcome. However, delayed presentation may lead to significant morbidity or even mortality. Twenty cases of cat bites to the hand and wrist were retrospectively reviewed between 2014 and 2018. Data included patient demographics, anatomical site of injury, microbiology results, method of treatment and surgical outcome. The subjects were 18 females and two males aged 27-86 years (mean age of 58 years). Eleven patients (Group A) were presented within 48 hours of their injury. Nine patients (Group B) presented later than 48 hours. Of these, 78% (n = 7) underwent multiple operations secondary to septic arthritis, osteomyelitis, necrotising fasciitis and deep collection. Mean length of hospital stay was 3.4 days in Group A, and 9.2 days in Group B, (p < .01). Four patients underwent digital or ray amputations. The index finger was the most common site of injury (45%). Almost 40% of cases had flexor tendon sheath infection of the fingers. Pasteurella species was isolated from 35% of infected wounds. Mean duration of antibiotic treatment and length of hospital stay were significantly longer in Group B (p < .05). Delayed presentation of infected cat bites increased the likelihood of more complicated surgeries such as amputation. Diabetic fingers with established peripheral neuropathy were more likely to undergo amputation. We recommend that any symptomatic cat bites to the upper limb, especially hand and wrist, must be treated promptly, essentially within 48 hours of injury, particularly in immunocompromised population.

Improved Survival of Computer-Assisted Unicompartmental Knee Arthroplasty: 252 Cases With a Minimum Follow-Up of 5 Years.

BACKGROUND: Unicompartmental knee arthroplasty (UKA) is an underutilized implant for medial tibiofemoral arthritis despite proven benefits in performance and reduced complications. This is likely related to registry recorded higher revision rates compared with total knee arthroplasty. It is our feeling that better component alignment resulting from the usage of computer-assisted surgery should improve longer-term functional results and survival of UKAs. METHODS: Between August 2003 and June 2007, 265 medial UKAs were performed in 264 consecutive patients using navigation. RESULTS: Eighty-eight women and 176 men with an average age of 51.7 (±4.63) years were assessed for function and survival over a follow-up period of 92.6 (63-120) months (7.7 years). The final survival rate over 5 years for this cohort was 97.6% at 5 years. CONCLUSION: We conclude that computer-assisted UKA, to treat medial tibiofemoral joint arthritis, produces 5-year survival rates that are comparable with total knee arthroplasty.

Radiological and Functional Outcomes in Computer Assisted Total Knee Arthroplasty Between Consultants and Trainees - A Prospective Randomized Controlled Trial.

Computer Aided Surgery has consistently shown superior alignment of components when compared to non-navigated jig based techniques. The aim of this study is to assess the mid-term clinical outcome of TKA performed by a consultant orthopedic surgeon, compared to trainee surgeons. Ninety-two patients were matched and randomly allocated to have CAS surgery performed by either a consultant or trainee and followed up prospectively for 5-years. Knee society scores, mechanical axis, tourniquet time and blood loss data were collected. Our study demonstrated that trainees were able to achieve equal coronal alignment (P=0.15), blood loss (P=0.45) and functional scores (P=0.15). The Consultant group had a significantly (P<0.001) shorter tourniquet time. We confirm that CAS can assist less experienced surgeons to reliably achieve good mid-term outcomes in TKA.

Refractures following removal of plates and elastic nails from paediatric forearms.

We assessed the risk for refractures following removal of elastic nails and plates from paediatric forearms. Out of 82 children who had 112 plates removed, seven patients (8.5%) had refractures when removals were within 12 months of implantation. Those aged 12 years or older were at risk. Out of 24 patients who had 38 nails removed, four patients (16.7%) had refractures and the risk was high when nails were removed within 6 months of insertion. Children aged 9 years or older were at risk. We do not recommend removal of forearm plates within 12 months and nails within 6 months of implantation.

Consenting operative orthopaedic trauma patients: challenges and solutions.

Guidelines exist to obtain informed consent before any operative procedure. We completed an audit cycle starting with retrospective review of 50 orthopaedic trauma procedures (Phase 1 over three months to determine the quality of consenting documentation). The results were conveyed and adequate training of the staff was arranged according to guidelines from BOA, DoH, and GMC. Compliance in filling consent forms was then prospectively assessed on 50 consecutive trauma surgeries over further three months (Phase 2). Use of abbreviations was significantly reduced (P = 0.03) in Phase 2 (none) compared to 10 (20%) in Phase 1 with odds ratio of 0.04. Initially, allocation of patient's copy was dispensed in three (6% in Phase 1) cases compared to 100% in Phase 2, when appropriate. Senior doctors (registrars or consultant) filled most consent forms. However, 7 (14%) consent forms in Phase 1 and eleven (22%) in Phase 2 were signed by Core Surgical Trainees year 2, which reflects the difference in seniority amongst junior doctors. The requirement for blood transfusion was addressed in 40% of cases where relevant and 100% cases in Phase 2. Consenting patients for trauma surgery improved in Phase 2. Regular audit is essential to maintain expected national standards.

Intraoperative radiation use by trainees during ankle fracture fixation.

Orthopedic trainees are assessed during training regarding their use of radiological screening during operative procedures. The authors investigated whether orthopedic trainees' use of fluoroscopic screening during ankle fixation operations varied with the 2 variables of consultant supervision and trainee experience. Data from operative fixation of isolated Weber B ankle fractures were reviewed. The intraoperative radiation dose was retrieved from radiographers' data. Operations performed by consultants were used as a control group (n=25 patients). Trainee supervision was assessed as "trainer in operating room (OR)" and "trainer out of OR." Regarding experience, the patients were divided into those operated on primarily by trainees in their first (n=36 patients) and in their last (n=34 patients) 3 years of formal specialist training. All trainee groups used more radiation than consultants. Supervision did not affect the radiation use of senior trainees (P<.05). Senior trainees used less radiation than their junior peers (P<.02). Junior trainees supervised by a trainer in the OR used less radiation than junior trainees supervised by a trainer outside of the OR (P<.05). During open reduction and internal fixation of ankle fractures, junior orthopedic trainees use less intraoperative radiation when they are supervised by a trainer in the OR. The more experience a surgeon has, the less fluoroscopic screening is used during operative ankle fixation.
