Radiological outcomes following open versus percutaneous fixation versus arthroscopically assisted percutaneous fixation of calcaneal fractures: a ten-year retrospective observational study.

BACKGROUND: Calcaneal fractures are often major injuries associated with considerable morbidity. The optimal surgical management of displaced calcaneal fractures remains contentious with open, percutaneous and arthroscopically assisted percutaneous approaches all offering potential benefits for patients. The aim of this study was to assess which of these three separate surgical approaches to the management of displaced calcaneal fractures provides the best radiographic deformity correction. METHODS: This is a retrospective observational study of all calcaneal fractures undergoing operative fixation at a single major trauma centre in the UK. The primary outcome was pre- and post-operative assessment of the deformity correction using radiographic parameters (angle of Gissane and Bohler's angle). Secondary outcomes included fracture configuration, complications and re-operation rate. RESULTS: Between 01/01/2009 and 31/12/2019, 152 calcaneal fractures in 134 patients underwent operative management via either an open or percutaneous approach. One-way ANOVA testing of the pre- and post-operative radiographic parameters demonstrated that an open approach offered superior post-operative correction of Bohler's angle when compared to percutaneous alone (p < 0.05); however, there was no difference in post-operative angle of Gissane (p > 0.05). The mean follow-up for complication and re-operation data was 3.5 years (range 0.1-12.4). Overall complication rate following all surgical fixation was 7.2% with a further 32.2% requiring further long-term surgical intervention for subtalar arthritis or removal of metalwork. CONCLUSION: Arthroscopically assisted percutaneous fixation does not offer superior radiographic deformity correction compared to percutaneous technique alone. Open fixation yielded improved correction of Bohler's angle when compared to percutaneous alone; however, there was no difference in post-operative angle of Gissane. LEVEL OF EVIDENCE: III.

The Use of Hindfoot Nails for Elderly Complex Distal Tibial and Ankle Fractures.

Elderly patients who sustain complex ankle or distal tibial fractures are often frail and comorbid and need surgery to contain the talus underneath the tibia in order to protect the soft tissue envelope and allow early unrestricted weightbearing. We performed a retrospective observational review of patients >65 years old who underwent a hindfoot nail fixation of an ankle or distal tibial fracture in our institution. Data collected included: injury sustained, open or closed injury, ASA grade, age at time of surgery, length of stay, postoperative mortality, complications, and further treatment. The primary outcome was reoperation. Secondary outcomes were infection and 1 year mortality. Seventy hind foot nailing procedures were undertaken. Sixty-three out of 70 patients were female. The average age of those who died within 1 year of surgery was 84 years. Forty-five out of 70 were open injuries. Eleven out of 70 patients died with 1 year of surgery (range 1-358 days postsurgery). Five out of 70 (7%) patients developed an infection. Four out of 5 of these injuries were open. Three out of 5 underwent removal of the nail due to infection. Two out of 5 had the infection suppressed with antibiotics. Ten out of 70 (14%) patients underwent locking bolt removal due to it backing out or being prominent and causing wound healing issues. Two out of 70 (3%) patients went on to have below knee amputations. Both were due to ongoing wound problems following open fractures. The hindfoot nail is an important implant when treating complex ankle and distal tibial fractures in an elderly population. It facilitates early mobilization to avoid deconditioning and other medical complications.

Percutaneous Strain Reduction Screws Are a Reproducible Minimally Invasive Method to Treat Long Bone Nonunion.

OBJECTIVES: (1) Evaluate whether initial results from percutaneous treatment of nonunion are reproducible (2) Estimate the relative cost of percutaneous treatment of nonunion versus traditional methods. DESIGN: Retrospective multicentre case series. SETTING: Four Level 1 trauma centers. PATIENTS/PARTICIPANTS: Fifty-one patients (34 men and 17 women) with a median age of 51 years (range 14-81) were treated for nonunion at a median of 10 months (range 4-212) from injury. INTERVENTION: Percutaneous strain reduction screws (PSRS). MAIN OUTCOME MEASURED: Union rates and time to union were compared for patients treated in the developing institution versus independent units as well as with previously published results. RESULTS: Forty-five (88%) patients achieved union at a median time of 5.2 months (range 1.0-24.7) confirming the previously published results for this technique. Comparable results were seen between the developing institution and independent units. No patients experienced adverse events beyond failure to achieve union. PSRS seems to offer savings of between £3177 ($4416) to £11,352 ($15,780) per case compared with traditional methods of nonunion surgery. CONCLUSIONS: PSRS is a safe, efficacious treatment for long bone nonunion and may be more cost-effective than traditional nonunion treatment methods. The promising initial results of this technique have now been replicated outside of the developing institution. LEVEL OF EVIDENCE: Therapeutic Level IV.

Low Rates of Survival Seen in Orthopedic Patients Receiving In-Hospital Cardiopulmonary Resuscitation.

INTRODUCTION: Despite awareness of overall poor survival rates following cardiopulmonary resuscitation (CPR), some orthopedic patients with significant comorbidities continue to have inappropriate resuscitation plans. Furthermore, in certain injury groups such as patients with hip fractures, survival outcome data are very limited; current discussions regarding resuscitation plans may be inaccurate. This study assesses survival in orthopedic patients following CPR, to inform decision-making between physicians, surgeons, and patients. METHODS: A dual center, retrospective cohort study was performed analyzing all orthopedic admissions that received CPR over a 25-month period, with a minimum of 1 year follow-up. National Cardiac Arrest Audit data, "mortality and morbidity" meeting records, National Hip Fracture Databases, and electronic notes were analyzed. Survival duration was measured, alongside reason for admission, location CPR occurred, and initial rhythm encountered. RESULTS: Thirty-two patients received CPR over the 25-month period (median age: 83; range: 30-96). Three (9%) of 32 patients survived to discharge. Only 1 of the 26 patients older than 65 years survived to discharge. Fifteen (47%) of 32 had hip fractures, where 4 (27%) of 15 of this group survived 24 hours; none survived to discharge. When recorded, 22 (92%) of 24 initially had a nonshockable rhythm. DISCUSSION: Cardiopulmonary resuscitation was conceptualized as a treatment for reversible cardiopulmonary causes. When used in trauma and orthopedic patients, especially older and/or hip fracture patients, it seldom led to hospital discharge. Different admission practices such as "front door" orthogeriatric reviews may explain the contrast in usage of CPR between the hospitals. CONCLUSION: Survival rates following CPR were very low, with it proving specifically ineffective in hip fracture patients. Although every decision about resuscitation should be patient centered and individualized, this study will allow clinicians to be more realistic about outcomes from CPR, particularly in the hip fracture group.

Tibiotalocalcaneal nail fixation and soft tissue coverage of Gustilo-Anderson grade 3B open unstable ankle fractures in a frail population; a case series in a major trauma centre.

BACKGROUND: Gustilo-Anderson grade 3B open ankle fracture-dislocations requiring stable fixation and soft tissue coverage are increasingly common in frail populations. METHODS: We identified all patients with open ankle fracture-dislocations treated with a tibiotalocalcaneal nail and soft tissue coverage over a five-year period. We retrospectively recorded pre-morbid status, fracture and soft tissue injury pattern, surgical details, post-operative mobility, length of hospital stay, complication and re-operation rate and survival. RESULTS: 21 ankles (20 patients) are included, all grade 3B open fractures. All patients were permitted to mobilise by one to six weeks post-surgery. One patient required further soft tissue surgery. Six patients had superficial wound colonization/infection, none developed deep infections. None of the nails have required removal. We observed a 15% three-month mortality rate. CONCLUSION: Tibiotalocalcaneal nail fixation and soft tissue coverage of unstable open ankle fractures in frail patients facilitates early return to ambulation with a low complication and re-operation rate.

A Case Series and Discussion on Surgical Treatment Strategy for Atypical Proximal Femoral Fractures Associated with Bisphosphonate Use.

The aim of this study was to determine the incidence of atypical femoral fractures in our local population, study their current outcomes and present a novel surgical strategy based on these data. Patients who received surgical fixation of an atypical pattern proximal femoral fracture over a four-year period were identified and followed up in the clinic until union, revision surgery or death. The local incidence of atypical femoral fractures is 1.1 per 1000 per annum amongst patients receiving bisphosphonates. Twelve fixation procedures were carried out in 10 patients. Intra-operative reduction and nailing led to an average deformity of 8.5° varus and 13° apex anterior. Five cases required revision surgery. Fifty percent of primary procedures resulted in radiographic union within two years. We suggest that the lateral side of the fracture should be considered a primary nonunion. We advocate undertaking a wedge excision to correct the bone to a valgus morphology and stabilising with an intramedullary nail and a lateral tension plate. Multicentre studies are needed to demonstrate the efficacy of any particular approach.

Accuracy of preoperative templating in total hip arthroplasty.

PURPOSE: To assess the accuracy of templating in total hip arthroplasty (THA). METHODS: Anteroposterior pelvic radiographs of 20 men and 33 women aged 17 to 80 (mean, 60) years who underwent uncemented THA of the right (n=24) and left (n=29) sides using a single prosthesis were reviewed. A 30-mm-diameter scaling ball was placed between the patient's legs for calculating the magnification factor (MF) of the radiographs. The planned THA was templated using computer software. The positioning of the scaling ball was measured. The preoperative MF was calculated as the size of the ball on radiograph divided by the true size of the ball times 100. The true MF was calculated as the size of the cup on radiograph divided by the true size of the cup times 100. The accuracy of the preoperative MF was calculated as the preoperative MF divided by the true MF times 100. RESULTS: The cup size and stem size were predicted correctly (within one size error) in 87% and 92% of the patients, respectively; no template size was greater than 3 size errors. The overall mean pre- and post-operative MFs differed significantly (122% vs. 127%, p<0.001), as did the mean postoperative MFs between males and females (126% vs. 128%, p=0.006). Assuming the MF was constant, and the postoperative measurement was the most accurate, the mean accuracy of preoperative MF was 96% (range, 89.6-99.9%), whereas the relative mean height of the scaling ball was 30 (range, 1-90) mm away from the correct height. The accuracy of the preoperative MF did not correlate with body mass index, the scaling ball position, and the accuracy of cup and stem templates. CONCLUSION: If the MF of 127% is constant across different patients, using a MF of 127% is more accurate than using the scaling ball technique.
