Risk factors for postoperative urinary retention in fragility hip fracture patients: a prospective study.

BACKGROUND: Postoperative urinary retention (POUR) among older patients with hip fractures is common and may result in delayed ambulation, prolonged hospital stays, and urinary tract infections. Although preoperative urinary catheter indwelling and early postoperative removal can prevent perioperative urinary retention, this condition may occur in some patients after catheter removal, which requires urinary catheter re-indwelling or intermittent catheterization. Therefore, this study aims to identify risk factors and develop a screening tool for postoperative urinary retention in patients who have undergone operative treatment for fragility hip fractures subsequent to urinary catheter removal. METHODS: A prospective cohort study of 145 fragility hip fracture in older patients who were operatively treated between September 2020 and May 2022 was conducted. All patients were evaluated for urine retention after urinary catheter removal using a bladder scan. In addition, factors related to urinary retention were collected and utilized for screening tool development. RESULTS: Of the included patients, 22 (15.2%) were diagnosed with POUR. A multivariable logistic regression model using a stepwise backward elimination algorithm identified the current use of drugs with anticholinergic effect (OR = 11.9, p = 0.012), international prostate symptom score (IPSS) ≥ 8 (OR = 9.3, p < 0.001), and inability to independently get out of bed within 24 h postoperatively (OR = 6.5, p = 0.051) as risk factors of POUR. The screening tool that has been developed revealed an excellent performance (AuROC = 0.85, 95%CI 0.75 to 0.91) with good calibration and minimal optimism. CONCLUSIONS: Current use of drugs with anticholinergic effects, IPSS ≥ 8, and inability to independently get out of bed within 24 h postoperatively are significant variables of POUR. For additional external validation, a proposed scoring system for POUR screening was developed. TRIAL REGISTRATION: The study protocol was retrospectively registered in The Thai Clinical Trials Registry (TCTR20220502001: 2 May 2022).

Defining Operative Indications in Lisfranc Injuries: A Systematic Review.

OBJECTIVE: The aim of this review was to determine operative indications for Lisfranc injuries. METHODS: A systematic review using a MEDLINE literature search was performed using the index "Lisfranc Injury" from 1980 onward using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines where applicable. Inclusion criteria were all clinical studies reporting on the management of Lisfranc injuries obtained via the search index, including case reports, review articles, cohort studies, and randomized trials. Non-English-language articles, inaccessible articles, those not relevant to the management of Lisfranc injuries (biomechanical, cadaveric, and technique articles), and those that did not explicitly state operative indications (vague or absent indications) were excluded. RESULTS: After identifying 737 studies, the full text of 391 studies was reviewed, and 58 reports providing explicit operative indications were included in the final analysis. Fifty-one (81.1%) studies provided diastasis cutoffs varying ≥2 mm (35/58; 60.4%), ≥1 mm (13; 22.4%), and ≥3 mm (3; 5.2%); the diastasis location was most commonly unspecified (31/58; 53.5%) or varied between combinations of metatarsal, tarsal, cuboid, and cuneiform bones (20/58; 27.6%). Specific imaging criteria for surgery included an avulsion fracture or fleck sign (3/58; 5.2%), arch height loss (3/58; 5.2%), and a tear on magnetic resonance imaging (5; 8.6%). The 11 (19%) studies defining operative indications in terms of classification schemes used the Nunley and Vertullo (8/58; 13.8%), Myerson (2; 3.5%), and Buehren (1; 1.7%) systems. Twenty-one (36.2%) studies provided multiple operative indications. CONCLUSION: The most common Lisfranc operative indications among the limited reporting studies varied from a 1- to 3-mm diastasis across several locations. It is imperative for operative indications to be reported with an increased frequency and in a homogenous fashion to guide the clinical management of these subtle injuries. LEVELS OF EVIDENCE: Level IV; systematic Review.

Evaluation of the implementation of multidisciplinary fast-track program for acute geriatric hip fractures at a University Hospital in resource-limited settings.

BACKGROUND: Hip fractures are common among frail, older people and associated with multiple adverse outcomes, including death. Timely and appropriate care by a multidisciplinary team may improve outcomes. Implementing a team to jointly deliver the service in resource-limited settings is challenging, particularly on the effectiveness of patient outcomes. METHODS: A retrospective cohort study to compare outcomes of hip fracture patients aged 65 or older admitted at Siriraj hospital before and after implementation of the Fast-track program for Acute Geriatric Hip Fractures. The primary outcome was the incidence of medical complications. The secondary outcomes were time to surgery, factors related to the occurrence of various complications, in-hospital mortality, and mortality at month 3, month 6 and month 12 after the operation. RESULTS: Three hundred two patients were enrolled from the Siriraj hospital's database from October 2016 to October 2018; 151 patients in each group with a mean age of 80 years were analyzed. Clinical parameters were similar between groups except the Fast-track group comprising more patients with dementia (37.1% VS 23.8%, p < 0.012). In the Fast-track group, there was a significantly higher proportion of patients underwent surgery within 72-h (80.3% VS 44.7%, p < 0.001) and the length of stay was significantly shorter (11 days (8-17) VS 13 days (9-18), p = 0.017). There was no significant difference in medical complications. Stratified analysis by dementia status showed a trend in delirium reduction in both patients with dementia and without dementia groups, and a pressure injury reduction among patients with dementia after the program was implemented but without statistical significance. There was no significant difference in mortality. CONCLUSIONS: The implementation of a multidisciplinary team for hip fracture patients is feasible in resource-limited setting. In the Fast-track program, time to surgery was reduced and the length of stay was shortened. Other outcome benefits were not shown, which may be due to incomplete uptake of all involved disciplines.

Functional Outcomes After Fracture-Dislocation of the Ankle.

Background. Fracture dislocation of the ankle represents a substantial injury to the bony and soft tissue structures of the ankle. There has been only limited reporting of functional outcome of ankle fracture-dislocations. This study aimed to compare functional outcome after open reduction internal fixation in ankle fractures with and without dislocation. Methods. A retrospective chart review of surgically treated ankle fractures over a 3- year period was performed. Demographic data, type of fracture, operative time and complications were recorded. Of 118 patients eligible for analysis, 33 (28%) sustained a fracture-dislocation. Mean patient age was 46.6 years; 62 patients, who had follow-up of at least 12 months, were analyzed for functional outcome assessed by the Foot and Ankle Outcome Score (FAOS). The median follow-up time was 37 months. Demographic variables and FAOS were compared between ankle fractures with and without dislocation. Results. The average age of patients sustaining fracture-dislocation was greater (53 vs 44 years, P = .017); a greater percentage were female (72.7% vs 51.8%, P = .039) and diabetic (24.2% vs 7.1%, P = .010). Wound complications were similar between both groups. FAOS was generally poorer in the fracture-dislocation group, although only the pain subscale demonstrated statistical significance (76 vs 92, P = .012). Conclusion. Ankle fracture-dislocation occurred more frequently in patients who were older, female, and diabetic. At a median of just > 3-year follow-up, functional outcomes in fracture-dislocations were generally poorer; the pain subscale of FAOS was worse in a statistically significant fashion. Levels of Evidence: Therapeutic, Level III.

Sequential Radiographic Evaluation During Closed Treatment of Distal Radius Fracture.

OBJECTIVES: To test the null hypothesis that there is no significant change in radiographic parameters, which determines an acceptable reduction, beyond 3 weeks in distal radius fractures with closed treatment. DESIGN: Retrospective review of a prospectively gathered registry of distal radius fractures. SETTING: Academic medical center. PATIENTS: Patients who underwent closed treatment of distal radius fracture. INTERVENTION: Sequential radiographic evaluation. MAIN OUTCOME MEASUREMENTS: Change of radiographic measurement including radial inclination, radial height, ulnar variance, articular tilt, teardrop angle, anteroposterior distance, intra-articular gap, and step-off. We compared postreduction radiographic parameters once within 2 weeks, at the third week, at cessation of immobilization, and analyzed the interobserver reliability test. RESULTS: There was a statistically significant difference between radiographic measurements, which determined an acceptable reduction between radiographs performed within 2 weeks versus the third week. Radial inclination and ulnar variance were statistically different at the third week compared with the time of cessation of immobilization. Seventy-seven percent of patients who had an acceptable reduction after 2 weeks maintained acceptable alignment at cessation of immobilization. Eighty-five percent of patients with acceptable reduction after 3 weeks maintained acceptable alignment at cessation of immobilization. Radial shortening >1.8 mm at the third week predicts an unacceptable radiographic outcome at cessation of immobilization (sensitivity 94.5% and specificity 90%). CONCLUSION: Radiographic parameters that determine acceptable reduction for closed treatment of distal radius fractures change minimally after 3-week postacceptable closed reduction. Radial shortening at the third week can be used to predict an unacceptable radiographic outcome. LEVEL OF EVIDENCE: Prognostic Level IV.

Musculoskeletal Health Literacy, Pain Catastrophization, and Sleep Quality: Effect on Functional Disability Scores.

Limited musculoskeletal health literacy, catastrophic pain thinking, and poor sleep quality may be associated with adverse long-term health outcomes, but are sparsely studied concomitantly in orthopedics. The purpose of this study was to assess how these factors influence baseline functional disability. Hand and wrist and foot and ankle patients presenting with a previously untreated complaint were enrolled and completed the Literacy in Musculoskeletal Problems questionnaire, Pain Catastrophization Scale (PCS), and Pittsburgh Sleep Quality Index (PSQI). Upper extremity patients completed the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and lower extremity patients completed the Foot and Ankle Outcome Score (FAOS) survey. DASH and FAOS scores were normalized to the same scale and termed "functional survey" (FS). Two hundred thirty-one patients (mean age 45.8 ± 16.8) were included in the analysis. PCS and PSQI were significantly correlated with FS score. The only other variables significantly correlated with FS score were insurance and diagnosis type. The variables PCS, PSQI, insurance, and diagnosis were entered into a multivariate analysis with FS score. All four variables significantly added to FS score in the model (R2 = .194, p < .001). Interventions that target both catastrophizing tendencies and sleep quality may independently improve functional outcomes. Further in-depth multifactorial research in this topic is critical to craft effective treatments with sustainable outcomes. (Journal of Surgical Orthopaedic Advances 28(2):144-149, 2019).

Prevalence and Risk Factors of Limited Musculoskeletal Health Literacy in the Outpatient Setting: A Logistic Regression Model.

INTRODUCTION: The purpose of this study was to determine the risk factors of limited musculoskeletal health literacy (MHL) in a general population of orthopaedic patients. METHODS: Patients presenting to either a foot or ankle surgeon or hand or wrist surgeon were given the Literacy in Musculoskeletal Problems (LiMP) questionnaire, a nine-item survey for assessing "limited" MHL (LiMP score < 6). After confirming group homogeneity, the two populations were analyzed together to determine factors significantly correlated with and predictive of limited MHL. RESULTS: Overall, 231 patients were included in the analysis. Average LiMP score was 5.4 ± 1.8, and 49% of participants had "limited" MHL. Chi-square analysis revealed that being non-Caucasian, using cigarettes, and having a less than college-level education were associated with a higher prevalence of "limited" MHL (P < 0.05). Logistic regression revealed that being of non-Caucasian race (P = 0.04) or having less than college-level education (P = 0.03) were significant independent predictors of "limited" MHL, with adjusted relative risks of 1.37 and 1.40, respectively. DISCUSSION: In this study, the patients at the greatest risk of limited MHL are often at the risk of many other complications. These results should be used as a groundwork to craft directives aimed at improving MHL and outcomes in these patients.

Timing of Open Reduction and Internal Fixation of Ankle Fractures.

Background. Unstable ankle fractures are treated with open reduction internal fixation (ORIF) to prevent posttraumatic arthritis. Typically, ORIF is performed as an ambulatory surgery several days to a few weeks after injury. It is unclear what effect this delay may have on functional outcome. This study aimed to assess the effect of timing of ankle ORIF on wound complications and functional outcome. Methods. A retrospective review of 121 patients who underwent ankle ORIF was performed. A total of 58 patients had a follow-up of at least 24 months. Time between injury and surgery greater than 14 days was defined as "delayed." Demographic variables, injury characteristics, length of surgery, and postoperative stay were documented. Comparison of demographic variables, wound complications, and functional outcome determined by Foot and Ankle Outcome Score (FAOS) was performed. Results. 118 patients were included. The duration between injury and surgery was 6 days in the "early" group and 19 days in the "delayed" group. There were no significant differences in demographic variables, injury characteristics, and length of surgery between the groups. Wound complications in the early and delayed groups were 5% and 11.8%, although this difference was not statistically significant. Among 58 patients who had a follow-up of at least 24 months, the median follow-up time was 38 (range, 24-76) months. Each subscale of FAOS demonstrated no significant difference. Conclusion. Ankle ORIF more than 14 days after injury did not significantly increase the rate of wound complication, nor did it impair ultimate functional outcome in this group. Levels of Evidence: Level III.

Anatomy of the ankle capsule: A cadaveric study.

Although bony and ligamentous injuries of the ankle are well understood, little is known about the degree to which injury of the ankle capsule can be a component of such injuries. The purpose of this study was to determine the dimensions of the ankle capsule and its relationship to adjacent structures. Thirteen fresh-frozen ankle specimens were systematically dissected. Methylene blue solution was injected to identify the dimensions of the ankle capsule. External dimensions were measured as the distance from the capsular reflection to the bony margin of the ankle. Internal dimensions were measured as the distance from the capsular attachment of the distal tibia, fibula, and talus to the cartilage margin. The anterior aspect of the capsule demonstrated the most proximal capsular reflection in all specimens. The most proximal reflections of the anteromedial, anterior middle and anterolateral capsule were 10.3, 13.5, and 9.8 mm, respectively. The most proximal reflections of the posteromedial, posterior middle and posterolateral region were 8.7, 6.2, and 3.5 mm, respectively. There was no capsular reflection over the medial malleolus and less than 1 mm over the posterior lateral malleolus. There was a confluence of the capsule and ligamentous complex on the medial side, and also with the transverse tibiofibular ligament about the posterolateral ankle. The most proximal attachment of the ankle capsule was located at the anterior aspect of the distal tibia. The medial and posterolateral capsules were confluent with the ligamentous complexes of the ankle in those regions. Clin. Anat. 31:1018-1023, 2018. © 2018 Wiley Periodicals, Inc.

Prevalence of Asymptomatic Achilles Tendinosis.

BACKGROUND: Most patients who sustain Achilles tendon ruptures (ATRs) have no clinical symptoms prior to ATR. The objective of this study was to define the prevalence of ultrasound-detectable Achilles tendinopathy in asymptomatic patients in an at-risk group. METHODS: This was a cross-sectional study that collected data from a group of volunteers. All participants were given IPAQ questionnaires to gauge daily activity level, in addition to a demographic form. Participants underwent a physical examination, Silfverskiold test, and an ultrasonographic examination to evaluate for presence of Achilles tendinopathy. Fifty-one volunteers (30 female, 21 male) and 102 Achilles tendons were assessed in this study. The mean age was 27.4±6.3, with an average BMI of 23.5±3.9. Ninety-two percent of participants were categorized as having moderate or high activity levels per the iPAQ questionnaire. RESULTS: Sixteen tendons had at least 1 abnormality: 10 (9.8%) had hypoechoic foci, 9 (8.8%) had calcifications, 1 (0.9%) had increased vascularity, and 1 (0.9%) had a low-grade interstitial tear. Approximately 40% of patients were noted to have a gastroc equinus contracture on Silfverskiold testing. In addition, 14.7% of patients with a gastroc equinus had a hypoechoic focus compared to 8.6% of patients without gastroc equinus ( P = .5003). Logistic regression analysis demonstrated that an increased BMI was a significant risk factor for having an Achilles tendon abnormality on ultrasonography ( P < .01, odds ratio = 1.41). CONCLUSION: In this study, 16% of the Achilles tendons were abnormal and had at least 1 abnormality on ultrasonography. This group of patients was generally young, healthy, and active, thus a group at risk for ATRs. Only 40% of patients had gastrocnemius equinus, although a slightly higher non-significant percentage of those with hypoechoic foci had gastrocnemius equinus. It may be advantageous to prophylactically treat these patients with rehabilitation exercises to minimize the risk of ATR. LEVEL OF EVIDENCE: Level II, comparative prognostic study.

Time to Diagnosis and Treatment of Surgical Site Infections in Foot and Ankle Surgery.

BACKGROUND: The time at which patients typically present with surgical site infections (SSI) following foot and ankle surgery has not been characterized. The primary aim of this study was to quantify the time to definitive treatment of SSIs. METHODS: We performed a retrospective review of 1933 foot and ankle procedures in 1632 patients from 2011 through 2015. Demographic and surgical data were collected. Time to presentation in cases diagnosed with postoperative wound complications or SSIs was analyzed. Wound complications were defined as any case with concerning wound appearance that subsequently resolved with antibiotic therapy alone. SSIs were defined as cases requiring operative irrigation and debridement (I&D) for successful definitive management. RESULTS: A total of 1569 procedures met inclusion criteria, with 17 SSIs (1.1%) and 63 wound complications (4.0%). Time between surgery and definitive treatment in the SSI group was significantly greater than in the wound complication group (28.2 ± 9.1 vs 13.4 ± 4.7 days, P < .00001). Eleven (64.7%) cases in the SSI group failed a trial of antibiotics prior to I&D, and 6 (35.3%) cases did not receive antibiotics prior to I&D. Antibiotic treatment prior to I&D did not significantly decrease the yield of intraoperative wound cultures (70% vs 100%, P = .51). CONCLUSION: In our cohort of patients, the time to diagnosis and treatment of SSIs was longer than that of wound complications. SSIs requiring operative intervention did not present until an average of 4 weeks after surgery. These data are of some benefit in trying to define and understand SSI. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

Increasing age in Achilles rupture patients over time.

BACKGROUND: The changing demographics of Achilles tendon rupture (ATR) patients have not fully been investigated. However, there has been a general suspicion that this injury is occurring in an increasingly older population, in terms of mean age. The aim of this study was to objectively show an increase in age in Achilles tendon rupture patients over time. METHODS: Published literature on Achilles tendon ruptures was searched for descriptive statistics on the demographics of patients in the studies, specifically mean and median age of Achilles tendon rupture patients, gender ratio, percentage of athletics-related injuries, percentage of smokers, and BMI. Linear regression analyses were performed to determine the trend of patient demographics over time. A Welch one-way ANOVA was carried out to identify any possible differences in data obtained from different types of studies. RESULTS: The patient demographics from 142 studies were recorded, with all ATR injuries occurring between the years 1953 and 2014. There was no significant difference in the mean age data reported by varying study types, i.e. randomized controlled trial, cohort study, case series, etc. (P=0.182). There was a statistically significant rise in mean age of ATR patients over time (P<0.0005). There was also a statistically significant drop in percentage of male ATR patients (P=0.02). There is no significant trend for percentage of athletics-related injuries, smoking or BMI. CONCLUSION: Since 1953 to present day, the mean age at which ATR occurs has been increasing by at least 0.721 years every five years. In the same time period, the percentage of female study patients with ATR injuries has also been increasing by at least 0.6% every five years. LEVEL OF EVIDENCE: Level III; Retrospective cohort study.

Timing of Antibiotic Prophylaxis for Preventing Surgical Site Infections in Foot and Ankle Surgery.

BACKGROUND: Surgical site infections (SSIs) are one of the most troublesome complications after foot and ankle surgery. Previous literature has emphasized the significance of appropriate timing of antibiotic prophylaxis. However, the optimal timing of antibiotic prophylaxis for SSI prevention is still inconclusive. Our study aimed to investigate the optimal timing of antibiotic administration and to elucidate the risk factors for SSIs in foot and ankle surgery. METHODS: A retrospective review of 1933 foot and ankle procedures in 1632 patients from January 1, 2011, through August 31, 2015, was performed. Demographic data; type, amount, and timing of antibiotic administration; incision; and closure time were recorded. Subsequent wound infection and incision and drainage procedure (I&D) within 30 days and 90 days were documented. Outcomes and demographic variables were compared between procedures in which antibiotics were administered less than 15 minutes and between 15 to 60 minutes prior to incision. A total of 1569 procedures met inclusion criteria. RESULTS: There were 17 cases (1.1%) of subsequent wound infection, of which 6 required a subsequent I&D within 30 days. There were 63 additional cases (4%) of wound complications, which did not meet SSI criteria. When comparing SSI and non-SSI groups, the only significant independent predictors were longer surgeries and nonambulatory surgeries (both P < .05). Stepwise multivariate logistic regression analysis demonstrated that 91.8% of the risk of an SSI could be predicted by ASA score and length of surgery alone. CONCLUSION: In foot and ankle surgeries, the timing of intravenous antibiotic prophylaxis did not appear to play a significant role in the risk of SSI. Host factors and duration of surgery appear to have played a much larger role in SSI than the timing of antibiotic prophylaxis. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Prevalence of Radiographic Osteoarthritis and Structural Abnormalities of the Hip in Patients with Contralateral Hip Fractures.

Background: The prevalence of osteoarthritis (OA) of the hip varies considerably among different races and ethnicities. Some bony abnormalities associated with the development of hip OA. Objective: To determine the prevalence of radiographic OA and structural abnormalities of the hip in patients with contralateral hip fractures. Material and Method: Pelvic AP radiographs of patients more than 60 years of age who had contralateral hip fractures were reviewed. Radiographic diagnosis of hip OA was determined by minimum joint space width <2 mm. Kellgren-Lawrence classification was also used for evaluation. Structural abnormalities of the acetabulum and proximal femur regarding femoroacetabular impingement were also assessed. Results: Plain radiographs of 152 patients with an average age of 77.4 years were included. One hundred and thirteen patients (74.3%) were female. Prevalence of radiographic OA of the hip (minimum joint space width <2 mm) was 9.9%. In addition, 9.2% of hips were Kellgren-Lawrence grade 2 or higher. Pistol grip deformity was found in 6 patients and all were male. Five patients (3.3%) had cross-over sign. No protrusio acetabuli was detected. Coxaprofunda was identified in 72 patients (47.4%). Average center-edgeangle was 37.1+6.2 degrees in hips with coxaprofunda, and 35.9+5.3 degrees in hips without coxaprofunda (p = 0.180). Conclusion: Prevalence of radiographic OA of the hip in patients with contralateral hip fractures was 9.9%. Coxaprofunda was a common radiographic finding.

Breakage of a Lag Screw of Cephalomedullary Nail: A Technique of Removal.

A broken lag screw of the cephalomedullary nail is a rare condition. Removal of the retained lag screw from the femoral head is also very challenging. This article describes a surgical technique and the modified instrument that was available in the operating room for removing the broken implant by closed technique.

Neuropathic pain in brachial plexus injury.

BACKGROUND: In Thailand, brachial plexus injury is a common traumatic injury that affects the function of the upper extremity. The current treatments focus mainly on improving the motor and sensory function. Apart from the motor and sensory deficit, these patients usually suffer from pain. OBJECTIVE: The purpose of this study was to determine the prevalence and factors that relate to neuropathic pain in patients with brachial plexus injury. METHODS: We collected data from March 2008 to July 2011. The DN4 Questionnaire was used to diagnose neuropathic pain in 95 patients. RESULTS: The prevalence of neuropathic pain was as high as 76%. Majority of patients presented with hypoesthesia to pin prick, hypoesthesia to touch and numbness. Severity of neuropathic pain was significantly correlated with the type of brachial plexus injury. There was no difference between demographic characteristics of patients. CONCLUSION: Our study showed that the prevalence of neuropathic pain was high in brachial plexus injured patients. Therefore, surgeons should be aware of this common, yet underestimated, problem in brachial plexus injured patients.

Radiation exposure in fluoroscopy of the shoulder: a comparison between mini and conventional C-arm image intensifier.

OBJECTIVE: To compare the radiation exposure of the primary surgeon while using the conventional c-arm and mini c-arm fluoroscopy at the shoulder MATERIAL AND METHOD: Twelve shoulders of six fresh cadavers were used to simulate this experimental study. Radiation exposure of the primary surgeon was measured at the head and neck region. The average radiation dose was measured using both the conventional c-arm and mini c-arm, then the findings were compared. RESULTS: Mean radiation energy of the conventional c-arm was significantly lower than the mini c-arm at 59.39 ± 1.43 kV and 70.58 ± 4.01 kV respectively (p < 0.001). Dose rates to which the primary surgeon was exposed from the conventional c-arm and the mini c-arm were 81.46 ± 30.37 µSv/hour and 87.54 ± 43.69 µSv/hour, respectively. However, the difference was not statistically significant (p = 0.875). CONCLUSION: There is no difference in the level of radiation safety for the primary surgeon when using the conventional c-arm vs. the mini c-arm for a fluoroscopic-assisted shoulder procedure. Therefore, selection of the methodology should be based on equipment availability and clinical considerations.

Removal of a broken cannulated femoral nail: a novel retrograde impaction technique.

This report presents a surgical technique to remove a broken cannulated nail from the femur. A Harrington rod was modified for retrograde impaction of the retained fragment. The broken implant was finally removed without complication. This particular procedure was safe, simple, and promising.
