Fibula Nail Outcomes in Soft Tissue Compromised Ankle Fractures

Background: To determine the clinical outcomes following fibula nail fixation and to identify the indication for the use of fibula nails in lower limb fractures. Methods: Retrospective study of adult patients from 2 major trauma centers (MTCs) and 9 trauma units (TUs) who underwent fibula nail fixation for AO/OTA 44 fractures between January 1, 2018, and October 31, 2020. Outcome measures included infection, metalwork complications, nonunion or malunion, time to union, and length of inpatient hospital stay. Results: Ninety-five patients were included, with a mean age of 66 years; 57.9% of patients were female. The average body mass index was 30. Sixty-nine patients (72.6%) sustained a Weber B and 24 (27.4%) sustained a Weber C fracture. In addition, 26.3% were open fractures and all patients had soft tissue compromise affecting the lateral malleolus. The calculated infection rate for fibula nail was 4.2% and metalwork complication rate was 5.2%. The nonunion and malunion rate was 8.4% and rate of removal of hardware was 2.1%. The average time to union was 12.5 weeks, and length of inpatient stay was 9.4 days (SD 10). Conclusion: This multicenter study demonstrates that use of a fibula nail appears to be a safe approach to treating patients who have a physiologically higher risk of surgery, poor skin condition, and a complex fracture pattern.

Arthroscopic Treatment of Iatrogenic Slipped Capital Femoral Epiphysis Screw Impingement and Associated Hip Pathology

Background: Screw impingement is an infrequently reported sequelae following in situ pinning of a slipped capital femoral epiphysis, but it may result in significant bony and chondrolabral degeneration. Hip arthroscopy may offer the advantage of screw removal in a minimally invasive manner under direct visualization, as well as providing the opportunity for management of concomitant hip pathology. Indications: A healthy, active 27-year-old woman with right hip dysfunction secondary to screw impingement and concomitant chondrolabral pathology following previous in situ pinning of a slipped capital femoral epiphysis. Technique Description: The patient elected to undergo arthroscopic removal of hardware, osteochondroplasty, and management of hip labrum pathology. After the screw was localized, a 2.8-mm pin was inserted down the cannulated center of the screw to prevent intraarticular displacement during removal. The screw and washer were removed intact, and femoroplasty was performed to remove the reactive bone and resolve the cam-type impingement. Acetabuloplasty was then performed to remove pincer-type impingement and provide an appropriate rim of bone for labral reconstruction. The pathologic labrum was then debrided and reconstructed with a semitendinosus allograft. Results: There were no immediate complications following surgery. Surgical management led to resolution of the patient’s mechanical symptoms and provided pain relief, which allowed return to prior baseline level of function. Discussion/Conclusion: Symptomatic screws that impinge the osteochondral and soft tissue anatomy of the hip require removal. Historically, these screws have been removed by open, mini-open, or percutaneous techniques. This case demonstrates the advantages of arthroscopic removal, as it affords the surgeon the ability to perform a dynamic examination, safely remove the screw, and directly visualize and manage concomitant hip pathology that may not be otherwise be recognizable. Further studies will be required to determine the ability of this technique to more clearly illustrate long-term improvement in function and prevention of the development of osteoarthritis.

Dorsal Spanning Plate for Perilunate Dislocations

Purpose The purpose of this study was to compare radiographic outcomes in patients treated with the traditional method of open reduction, internal fixation (ORIF) and casting as compared with those treated with ORIF and dorsal spanning plate (DSP) fixation. We hypothesized that the application of a DSP to augment the repair of perilunate dislocations would maintain carpal stability while also allowing early loadbearing through the carpus. Materials and Methods This is a retrospective radiographic review of patients with a perilunate dislocation, who were treated with ORIF and casting or ORIF with a dorsal spanning plate between 2012–2018. Scapholunate (SL) and lunotriquetral (LT) intervals were measured immediately after the index surgery and after scheduled hardware removal. A total of 28 patients met inclusion criteria, including 13 cases with traditional treatment and 15 cases with dorsal spanning plate fixation. Results Comparison of the change in SL interval and LT interval between the 13 patients in the traditional treatment group and the 15 patients in the DSP group did not yield any clinically relevant variation after statistical analysis. Both groups demonstrated minimal change in the radiographic markers of carpal stability from postoperative radiographs obtained immediately after the index repair and after the removal of hardware. Conclusion DSP fixation placed at the index surgery with early loadbearing for the treatment of perilunate dislocation is not inferior to the current mainstay of treatment consisting of cast immobilization without loadbearing and does not confer any increased carpal instability in comparison to ORIF and casting.

Outcomes of Total Knee Arthroplasty in Patients with Prior Hardware: A Case–Control Study Using Handheld Navigation

Presence of hardware in juxta-articular location poses challenge during total knee arthroplasty (TKA). When present in distal femur, it precludes the use of an intramedullary femoral jig during TKA often necessitating removal of hardware leading to prolonged surgery, higher risk of complications, and inferior results. We conducted a case–control study to assess the outcome of TKA among patients with post-traumatic arthritis using a handheld navigation system to perform bone cuts allowing retention of hardware in situ. In 15 patients with post-traumatic arthritis and hardware around the knee (Group A), none or part(s) of hardware were removed while performing TKA. These patients were matched to 15 patients who underwent TKA with handheld navigation for primary OA knee (Group B). The perioperative outcomes assessed were operative time, intraoperative blood loss, length of hospital stay, complications, and 30 days reoperation rate. Clinical outcomes were assessed by using Knee Society Score (KSS) and radiological outcomes using mechanical axis and coronal and sagittal component angles. Mean age of patients at surgery were 65.67 years (Group A) and 66.73 years (Group B). Mean operative time and blood loss were significantly higher in Group A as compared with Group B. At the mean follow-up of 34 months, KSS significantly improved in both the groups. However, there was no statistically significant difference in the clinical and radiological outcomes between the two groups. One patient in Group A developed wound dehiscence and had to undergo debridement and flap coverage within 30 days. The use of navigation helps surgeons in gaining proper limb alignment and implant positioning without complete removal of hardware.

Hyoid Suspension With UPPP for the Treatment of Obstructive Sleep Apnea

This retrospective evaluation of surgical outcomes for hyomandibular suspension when performed with uvulopalatopharyngoplasty (UPPP) for the treatment of obstructive sleep apnea (OSA). Thirty-nine patients with moderate-to-severe OSA were treated with hyoid myotomy and suspension and uvulopalatopharyngoplasty. Patients underwent hyoid advancement and suspension to the mandible (Encore System) with either staged or concurrent UPPP. The primary outcome was a successful surgical result, defined as an apnea hypopnea index (AHI) lower than 20, and a 50% or greater decline in AHI on postoperative polysomnography. Successful surgical results were achieved in 30 (76.9%) out of 39 patients. The mean preoperative AHI improved 69.2% from 49.9 ± 25.6 to 15.4 ± 14.9 ( P < .001) postoperatively. All patients reported clinical improvement of symptoms. There were 4 wound complications and one infection requiring removal of hardware. For patients with multilevel obstructive sleep apnea, hyoid advancement and suspension to the mandible appears efficacious when performed in conjunction with uvulopalatopharyngoplasty.

Outcomes following surgical management of vagus nerve stimulator–related infection: a retrospective multi-institutional study

OBJECTIVESurgical site infection (SSI) is a rare but significant complication after vagus nerve stimulator (VNS) placement. Treatment options range from antibiotic therapy alone to hardware removal. The optimal therapeutic strategy remains open to debate. Therefore, the authors conducted this retrospective multicenter analysis to provide insight into the optimal management of VNS-related SSI (VNS-SSI).METHODSUnder institutional review board approval and utilizing an institutional database with 641 patients who had undergone 808 VNS-related placement surgeries and 31 patients who had undergone VNS-related hardware removal surgeries, the authors retrospectively analyzed VNS-SSI.RESULTSSixteen cases of VNS-SSI were identified; 12 of them had undergone the original VNS placement procedure at the authors’ institutions. Thus, the incidence of VNS-SSI was calculated as 1.5%. The mean (± standard deviation) time from the most recent VNS-related surgeries to infection was 42 (± 27) days. Methicillin-sensitive staphylococcus was the usual causative bacteria (58%). Initial treatments included antibiotics with or without nonsurgical procedures (n = 6), nonremoval open surgeries for irrigation (n = 3), generator removal (n = 3), and total or near-total removal of hardware (n = 4). Although 2 patients were successfully treated with antibiotics alone or combined with generator removal, removal of both the generator and leads was eventually required in 14 patients. Mild swallowing difficulties and hoarseness occurred in 2 patients with eventual resolution.CONCLUSIONSRemoval of the VNS including electrode leads combined with antibiotic administration is the definitive treatment but has a risk of causing dysphagia. If the surgeon finds dense scarring around the vagus nerve, the prudent approach is to snip the electrode close to the nerve as opposed to attempting to unwind the lead completely.

A Study Comparing the Outcomes of Transverse Ulnar Shortening Osteotomy Fixed with a DCP to Oblique Osteotomy Fixed with a Procedure Specific Plate

Background: Ulnar shortening osteotomy (USO) is a well-established procedure for ulnar impaction syndrome. Various types of osteotomies have been described. Methods: A retrospective cohort study was conducted to compare the results of transverse osteotomy (TO) fixed with a small fragment dynamic compression plate (Synthes, Pennsylvania, USA), to oblique osteotomy (OO) fixed with a procedure specific plate and instrumentation system (Acumed LLC, Oregon, USA). A total of 39 patients underwent TO and 62 patients underwent OO between 2007 and 2016. The main outcomes compared were rate of union, duration of radiological healing, implant removal rate and other complications. Results: The two groups were comparable with regards to demographics, side operated and smoking status (p > 0.05). Amongst the TO group; 36 out of 39 patients (92.3%) achieved union, 3 patients (7.7%) developed non-union. Six out of the 36 healed TO (16.6%) required removal of hardware due to implant-related pain. No other complications were recorded amongst TO group needing surgical intervention. Amongst the OO group, 2 of the early cohort of 62 patients (3.2%) sustained acute failure of the metalwork due to technical error. One of the remaining 60 patients (1.6%) developed non-union giving an overall union rate of 95.2%. Two patients out of 59 healed OO (3.3%) required removal of hardware. Conclusions: Although there were 2 early failures, there was a trend towards improved union rate with OO, but this did not reach statistical significance (p > 0.05). There was a significantly higher hardware removal rate recorded in TO group (p = 0.023). The OO showed shorter duration for radiological healing than TO (p < 0.05). USO performed with an OO and fixed with procedure specific plate has lower implant removal rate, a shorter duration for radiological healing and comparable union rate to TO fixed with DCP, but needs careful attention to detail.

Elective removal vs. retaining of hardware after osteosynthesis in asymptomatic patients—a scoping review

Background Osteosynthesis is the internal fixation of fractures or osteotomy by mechanical devices (also called hardware). After bone healing, there are two options: one is to remove the hardware, the other is to leave it in place. The removal of the hardware in patients without medical indication (elective) is controversially discussed. We performed a scoping review to identify evidence on the elective removal of hardware in asymptomatic patients compared to retaining of the hardware to check feasibility of performing a health technology assessment. In addition, we wanted to find out which type of evidence is available. Methods A systematic literature search was performed in PubMed, Embase, EconLit, and CINAHL (November 2019). We included studies comparing asymptomatic patients with an internal fixation in the lower or upper extremities whose internal fixation was electively (without medical indication) removed or retained. We did not restrict inclusion to any effectiveness/safety outcome and considered any comparative study design as eligible. Study selection and data extraction was performed by two reviewers. Results We identified 13476 titles/abstracts. Of these, we obtained 115 full-text publications which were assessed in detail against the inclusion criteria. We included 13 studies (1 RCT, 4 cohort studies, 8 before-after studies) and identified two ongoing RCTs. Nine assessed the removal of the internal fixation in the lower extremities (six of these syndesmotic screws in ankle fractures only) and two in the upper extremities. One study analysed the effectiveness of hardware removal in children in all types of extremity fractures. Outcomes reported included various scales measuring functionality, pain and clinical assessments (e.g. range of motion) and health-related quality of life. Conclusions We identified 13 studies that evaluated the effectiveness/safety of hardware removal in the extremities. The follow up times were short, the patient groups small and the ways of measurement differed. In general, clinical heterogeneity was high. Evidence on selected topics, e.g. syndesmotic screw removal is available nevertheless not sufficient to allow a meaningful assessment of effectiveness.

Impact of Postoperative Complications on Fulfillment of Expectations after Orthopaedic Foot and Ankle Surgery

Category: Other Introduction/Purpose: Fulfillment of patients’ expectations following foot and ankle surgery has been previously studied and validated in assessing patient-reported outcomes (PROs). While this assessment has been shown to correlate well with patient satisfaction and PROs, the impact of postoperative complications on fulfillment of expectations is unknown. The aim of this study is to therefore investigate the impact of postoperative complications on fulfillment of patients’ expectations. Methods: Preoperatively, patients completed a validated Foot and Ankle expectations survey consisting of 23 questions encompassing domains including pain, ambulation, daily function, exercise, and shoe wear. At 2 years postoperatively, patients answered how much improvement they received for each item cited preoperatively. A fulfillment proportion (FP) was calculated as the amount of improvement received versus the amount of improvement expected. The FP ranges from 0 (no expectations fulfilled), between 0 and 1 (expectations partially fulfilled), 1 (expectations met), to greater than 1 (expectations surpassed). In addition, patient-reported outcomes (FAOS), satisfaction, and Delighted-Terrible scale (how they would feel if asked to spend the rest of their life with their current foot/ankle symptom) were collected at final follow-up. Chart review was performed to identify patient demographics, comorbidities, pain management, and postoperative complications, which were classified as minor (infection requiring antibiotics) or major (unplanned return to OR, reoperation, or revision). Results: Of the 271 patients (mean age 55.4 years, 65% female), 31 (11.4%, mean age 53.6, 58% female) had a postoperative complication; 27 major (17 revisions, 10 removal of hardware due to pain/infection) and 6 minor (6 superficial infections requiring antibiotics). Complications were associated with significantly worse FP (0.69 +- 0.45 vs 0.86 +- 0.40, p=0.02). Average time from complication to completion of fulfillment survey was 15 (+-3.6) months. Having a complication significantly correlated with worse satisfaction, Delighted-Terrible scale, and FP (p<0.001). FAOS domains were similar preoperatively; postoperatively patients without complications had significantly higher ADL and QoL scores (p<0.05). Demographically, there was no difference in age, sex, BMI, Charlson Comorbidity Index, depression/anxiety, or pain management between the two groups. The groups were similar in diagnoses. Conclusion: Our data suggests that postoperative complications following foot and ankle surgery are associated with worse patient-reported fulfillment of their surgical expectations. This finding is independent of preoperative expectations, and correlates with several validated outcomes measures including patient satisfaction. Therefore, while patient fulfillment following foot and ankle surgery is multifactorial, the importance of preoperative education and counselling for potential complications should not be overlooked.
