Anterior Plate-Supported Cannulated Screw Surgery for Ankle Arthrodesis: Clinical and Radiologic Results in Patients with Trauma-Related End-Stage Ankle Osteoarthritis.

BACKGROUND This retrospective study included 31 patients from 2 centers in Türkiye with posttraumatic ankle osteoarthritis treated with anterior tibiotalar arthrodesis using an anterior plate and cannulated screw fixation, with 6 months of follow-up. MATERIAL AND METHODS In this bi-center study, conducted between January 2018 and July 2022, we retrospectively reviewed the digital records of 31 patients with end-stage posttraumatic ankle osteoarthritis who were treated with anterior tibiotalar arthrodesis surgery using 2 or 3 cannulated screws and the anterior plating technique. Data on age, gender, comorbidities, and smoking were recorded, as were operative technique and graft use. Union characteristics, complications, visual analog scale (VAS) results, and Maryland functional scoring were assessed preoperatively and at the 6-month follow-up visit. RESULTS The mean age of the 31 (n=13 male, n=18 female) patients was 55.5 (19-82) years. The union findings were good in 26 (83.9%) of the patients and late in 3 (9.7%) of them. Nonunion was seen in 2 (6.5%) patients. Complications were observed in 7 (22.6%) patients. Union formation was statistically significantly prolonged among the cases with complications (P=0.002). The smoking rate was significantly higher in patients encountering complications (P=0.001). Among cases with complications, the VAS and Maryland scores recorded in the postoperative sixth month were significantly higher (P=0.027, P=0.018, respectively). The mean union time was 13.5±6.5 weeks among all of the patients. CONCLUSIONS Our study showed that cannulated screw fixation, strengthened with the common and easy-to-supply anterior reconstruction plating technique, had high fixation power and good functional results in patients with end-stage posttraumatic ankle osteoarthritis.

Patient reported and functional outcome measures after surgical salvage procedures for posttraumatic radiocarpal osteoarthritis - a systematic review.

BACKGROUND: Posttraumatic wrist osteoarthritis is an irreversible and often progressive condition. Many surgical treatments, used in (daily) practice, aim to relieve symptoms like pain and restore function. The aim of this systematic review is to assess the patient reported and functional outcomes of the most common surgical interventions in patients with posttraumatic wrist osteoarthritis. This overview can help clinicians select the best treatment and manage patient's expectations. METHODS: A literature search was performed in Pubmed, Embase and Cochrane for articles published between 1990 and November 2022 according to the PRISMA guidelines. The study protocol has been registered in the PROSPERO database (CRD42017080427). Studies that describe patient reported outcomes (pain and Disability of Arm, Shoulder and Hand (DASH) -score) and functional outcomes (range of motion (ROM) and grip strength) after surgical intervention with a minimal follow-up of 1 year were included. The identified surgical procedures included denervation, proximal row carpectomy, interpositional- and total arthroplasty, and midcarpal-, radiocarpal- and total arthrodesis. The pre-and postoperative outcomes were pooled and presented per salvage procedure. RESULTS: Data from 50 studies was included. Pain score improved after all surgeries except denervation. Flexion/extension decreased after radiocarpal arthrodesis, did not show significant changes after proximal row carpectomy, and improved for all other surgeries. DASH score improved after arthroplasty, proximal row carpectomy and midcarpal arthrodesis. Grip strength improved after interposition arthroplasty and partial arthrodesis. CONCLUSION: Evidence from this review did not support the indication for denervation in this particular patient population. In patients with SLAC/SNAC II, proximal row carpectomy might be favourable to a midcarpal arthrodesis solely based on better FE ROM of the radiocarpal joint after proximal row carpectomy. In terms of radiocarpal mobility, total wrist arthroplasty might be preferred to radiocarpal arthrodesis in patients with osteoarthritis after a distal radius fracture. More uniform measurements of outcomes would improve the understanding of the effect of surgical treatments of the posttraumatic osteoarthritic wrist.

Arthrodesis of distal interphalangeal and thumb interphalangeal joint: a retrospective cohort study of 149 cases.

BACKGROUND: Arthrodesis of finger joints is often the last line of treatment of severe pain due to osteoarthritis, rheumatoid arthritis, or mallet finger. At the Department of Orthopedic and Hand Surgery, Örebro University Hospital (ÖUH) in Sweden, the Kirschner-wire technique was standard until 2020, when the headless compression screw technique was introduced as a complement. There is no consensus on which method is superior. The purpose of this study was to examine the outcomes and complications associated with distal interphalangeal (DIP) joint and thumb interphalangeal (IP) joint arthrodesis, and to see whether these correlated with patient-dependent and treatment-related factors. METHODS: In a retrospective cohort study, we evaluated a total of 149 consecutive arthrodeses (118 DIP joint and 31 thumb IP joint) performed between 2012 and 2022. The primary outcome was risk factors for complications after arthrodesis. RESULTS: Osteoarthritis was the most common indication (56%) for arthrodesis. The majority of the patients were females (74%), and the median age was 62 (range 18-86). The complication frequency was 35%, with infection being the most common (25%). Time to completed follow up was < 12 weeks in the majority of the cases (58%). There were no significant differences in complication rate between the 136 joints operated using Kirschner wire and the 13 joints operated using headless compression screws. There was no significant increased risk of complications among smokers or patients with rheumatoid arthritis. Diabetes and surgeon experience had a significant influence on the risk of complication (p = 0.036 and p = 0.006, respectively). CONCLUSIONS: Osteoarthritis was the most common indication for arthrodesis and postoperative complications occurred at a rate similar to that reported in the existing literature. Diabetes and surgeon experience were identified as factors increasing the risk of postoperative complications in these DIP/thumb IP joint arthrodeses. However, there was no significant difference between the two techniques (Kirschner wire and headless compression screws) regarding complications. Further studies are needed in order to determine the optimal type of operation and choice of implant. TRIAL REGISTRATION: Researchweb CRIS #280,998, 26th of July 2023.

Midfoot Fusion Using Superconstructs for the Charcot Foot: Current Techniques and Complications.

Neuroarthropathy of the foot and ankle presents a series of challenges. The treating physician faces a perfect storm of pathomechanics, deformity, and medical comorbidities. Successful treatment requires a systematic approach in diagnosis, nonsurgical management, surgical management, and long-term maintenance of the affected extremity. Nonsurgical care of the Charcot foot remains the mainstay of treatment and is successful in most cases. Surgery has become more accepted for patients with severe deformity. The concept of a superconstruct has been introduced to describe modern surgical techniques and implants that have been developed since the early 2000s where stability and durability are maximized. A superconstruct is defined by four factors: (1) fusion is extended beyond the zone of injury to bridge the area of bony dissolution; (2) aggressive bone resection is performed to allow for adequate reduction of deformity without undue tension on the soft-tissue envelope; (3) stronger implants are used than for nonneuropathic fusion procedures, including some specifically developed for fixation of the Charcot foot; and (4) the devices are applied in a position that maximizes mechanical stability to allow the implants to become load sharing. It is important to review the current techniques and implants used in fusion of the neuropathic midfoot and discuss the expected outcomes and complications based on the authors' experience.

A Changing Landscape in the Surgical Management of Wrist Arthritis: An Analysis of National Trends From 2009 to 2019.

PURPOSE: The purpose of this study was to analyze the trends in the annual volume and incidence of proximal row carpectomy (PRC), four-corner fusion (4CF), total wrist arthrodesis (TWF), and total wrist arthroplasty (TWA) from 2009 to 2019 in the United States. METHODS: The IBM Watson Health MarketScan databases were queried to identify annual case volumes for PRC, 4CF, TWF, and TWA from 2009 to 2019. The annual incidence of these procedures was then calculated based on the population estimates from the US Census Bureau. Trends in annual volume and incidence over the study period were evaluated using regression line analysis. Further subgroup analysis was conducted based on age and region. RESULTS: From 2009 to 2019, the total case volumes for the four procedures increased by 3.4%, but the incidence decreased by 2.8%. However, PRC case volume and incidence trends significantly increased (38.2% and 29.7%, respectively), whereas 4CF remained constant. Conversely, the case volume and incidence of TWA significantly decreased (-52.2% and -54.5%, respectively), whereas TWF remained constant. When stratified by age, all four procedures decreased in the <45-year-old cohort (combined -35.1%) significantly for 4CF, TWF, and TWA. TWA decreased significantly in the <45-year-old and 45- to 65-year-old cohorts (53.6% and 63.2%, respectively). For age >65 years, the total case incidence increased by 98.9%, including a significant positive trend in TWF (175%). CONCLUSIONS: Surgical management of wrist arthritis remains a controversial issue. However, PRC has gained recent support in the literature, and our results reflect this shift, even for the <45-year-old cohort. Furthermore, TWA declined, despite reports of positive early outcomes for fourth-generation implants. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

Glenohumeral arthrodesis outcomes and complications: a systematic review.

BACKGROUND: The purpose of this study was to systematically review the evidence in the literature to determine the clinical outcomes following glenohumeral arthrodesis. METHODS: Two independent reviewers performed a literature search in the PubMed database based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Studies were included if they reported on outcomes following shoulder arthrodesis from the years of 2000-2022. Functional outcomes that were collected included the Subjective Shoulder Value, American Shoulder and Elbow Surgeons shoulder index score, visual analog scale pain score, and Oxford Shoulder Score. Range-of-motion data were also collected. RESULTS: This review included 17 studies, with a total of 316 patients, that met the inclusion criteria. The majority of the patients were male (67.4%), and the average age was 38.4 years (range, 7-82 years). The overall fusion rate was 88.7%, and the time to fusion was on average, 3.9 months (range, 2-8 months). Shoulder arthrodesis resulted in improvement in each of the functional outcomes assessed: Subjective Shoulder Value (preoperatively, 18.8; postoperatively, 43.9; and percent change, 132.8%), American Shoulder and Elbow Surgeons shoulder index score (postoperatively, 62.1), visual analog scale pain score (preoperatively, 8.5; postoperatively, 3.03; and percent change, 62.4%), and Oxford Shoulder Score (preoperatively, 9.4; postoperatively, 30.9; and percent change, 328.7%). The abduction, forward flexion, external rotation, and internal rotation range-of-motion measurements postoperatively were 57°, 64°, 3°, and 48°, respectively. Complications were reported in 33.6% of patients, with fractures (20.9%) and infections (18.6%) being the most common sources of complication. CONCLUSION: Shoulder arthrodesis provides improvement in functional outcomes for end-stage glenohumeral injuries; however, it is also associated with high rates of complications.

Floating Knee Arthrodesis After Prosthetic Knee Infection: A Report of 48 Cases.

BACKGROUND: Knee arthrodesis is a means of avoiding above-knee amputation after a prosthetic joint infection (PJI). The objective of this study was to analyze the results of floating knee arthrodesis in patients who had a history of aprosthetic knee infection. The analysis consisted of determining reinfection rates, functional results, and the survival of arthrodesis. METHODS: There were 48 patients who underwent a cemented floating knee arthrodesis in cases of PJI retrospectively included in the study, having been operated on between 2012 and 2020. In addition to being evaluated clinically, analytically, and radiographically, the patients were assessed functionally by means of a newly-created scale. RESULTS: At a mean follow-up of 4 years (1 year to 9 years), 7 patients suffered reinfection (14.6%). The recurrence of infection was not observed to be significantly affected by sex (P = .16), age(P = .09), or the type of surgery previously undergone (P = .18), nor was the McPherson Host Grade (P = .4) observed to have a significant effect. Patients who had a McPherson Limb Grade 3 were more likely to suffer reinfection than those with a McPherson Limb Grade 2 (P = .034). There were 26 patients (54%)fully evaluated and scored on the Knee Arthrodesis Functional Scale(BAOR). For 11 patients (42%), the results were evaluated as excellent, for 11 (42%) acceptable, for 3 (12%) low, and for 1(4%) poor. CONCLUSION: The arthrodesis nail is an effective and safe procedure for patients who have a recurrent PJI, providing an effective alternative when the criteria for a new revision total knee arthroplasty are not met.

Pediatric Spastic Wrist Contractures Can Be Well Managed With Wrist Arthrodesis.

BACKGROUND: Severe spastic wrist contractures secondary to cerebral palsy (CP) or alike can have significant implications for patient hand function, hygiene, skin breakdown, and cosmesis. When these contractures become rigid, soft tissue procedures alone are unable to obtain or maintain the desired correction. In these patients' wrist arthrodesis is an option-enabling the hand to be stabilized in a more functional position for hygiene, dressing, and general cosmesis, though are patients satisfied? METHODS: All children who had undergone a wrist arthrodesis for the management of a severe wrist contracture at Shriners Hospital, Portland between January 2016 and January 2021 were identified (n=23). A chart review was undertaken to obtain data-demographic, operative, clinical, and radiographic. All patients were then contacted to participate in 2 patient-reported outcome questionnaires (74% response agreement), a numerical rating scale (NRS), based on the visual analog scale (VAS) and the disability analog scale (DAS). Results were assessed with the aid of descriptive statistics, means and percentages with the primary focus of determining overall patient satisfaction with the procedure. RESULTS: Twenty-three patients were included in the review, and 74% took part in the prospective survey. Included were 10 patients with hemiplegia, 4 with triplegia, 7 with quadriplegia, 1 with a diagnosis of Rhett syndrome, and 1 with a history of traumatic brain injury. All patients achieved radiologic union by a mean of 8 weeks, and 87% obtained a neutral postoperative wrist alignment. The NRS showed 88% of patients were highly satisfied with their results; specifically, 82% had an improved appearance, 53% improved function, 71% improved daily cares, and 65% improved hygiene. The postoperative DAS score averaged 4.7 of 12 indicating mild disability. When looking at how a patient's diagnostic subtype affected outcome results, patients with triplegia reported less improvement and greater disability on the NRS and DAS, averaging 9.5 (severe disability on the DAS). The GMFCS classification had less correlation with outcomes. CONCLUSION: Wrist arthrodesis is a good option for the management of pediatric spastic wrist contractures, with limited complications and an overall high patient/carer satisfaction rate. LEVEL OF EVIDENCE: Level IV-case series.

Comparisons of ankle arthrodesis with different internal fixation methods in the treatment of post-traumatic osteoarthritis.

BACKGROUND: The aim of this study was to explore the clinical efficacy of ankle arthrodesis with different internal fixation methods in the treatment of post-traumatic osteoarthritis. METHODS: We collected 85 patients with post-traumatic osteoarthritis who underwent different ankle arthrodesis between December 2015 and December 2020. The operation performance, complication rate, hindfoot alignment, talus tilt angle, visual analogue scale (VAS), and American Orthopedic Foot and Ankle Society (AOFAS) score were preoperatively and postoperatively evaluated. RESULTS: In an anterior approach, the locking plate-fixation exhibited a similarity in operation time, incision length, postoperative drainage, bone fusion, hindfoot alignment, and talus tilt angle with fibula support compression screw-fixation, but it was better in increasing postoperative AOFAS. The locking plate-fixation in the anterior approach had lower operation time, incision length, and postoperative drainage than that in the lateral approach. In addition, the lateral locking plate combined with posterolateral compression screw fixation (LLPPCSF) presented shorter bone fusion time, higher AOFAS score, and lower complication rate than either plate- or screw-fixation alone. CONCLUSION: Lateral locking plate fixation was better than fibula support compression screw fixation in relieving postoperative pain. Anterior locking plate fixation was more time-saving and less invasiveness than lateral locking plate fixation, but its application was limited in low degree of ankle deformation. LLPPCSF was the most effective in improving bone fusion and postoperative pain, considering an optimal option for the treatment of post-traumatic osteoarthritis.

Minimally invasive arthroscopy-assisted arthrodesis for thumb carpometacarpal osteoarthritis.

INTRODUCTION: Arthrodesis is a reliable surgical procedure for treatment of thumb carpometacarpal (CMC) osteoarthritis that provides hand strength and pain relief. Locking plate fixation is a common technique that provides rigid fixation and a high rate of bone union; however, it requires extensive surgical exploration of the first metacarpal and trapezium. Here, we report the surgical outcome of minimally invasive arthroscopy-assisted thumb CMC arthrodesis that preserves soft tissue supplying the blood flow to the bones. MATERIALS AND METHODS: Nine thumbs of nine patients who underwent arthroscopy-assisted thumb CMC arthrodesis were retrospectively analysed (mean postoperative follow-up, 19.7 months). We investigated the time from surgery to bone union, grip strength, pinch strength (pulp and key), range of motion (ROM) of the thumb, visual analogue scale (VAS) score for pain, Disabilities of Arm, Shoulder, and Hand (DASH) score, and Hand20 questionnaire score preoperatively and at the final follow-up. RESULTS: Bone union was observed in eight of the nine patients. The mean time to bone union was 2.9 months (range 8 weeks-9 months). Although grip strength changed from 24.0 kg preoperatively to 25.8 kg at the final follow-up (not significant), the pulp pinch strength and key pinch strength significantly increased from 2.3 kg and 3.7 kg preoperatively to 3.8 kg and 5.6 kg at the final follow-up, respectively. No significant change occurred in the thumb ROM. The DASH score, Hand20 questionnaire score, and VAS score for pain significantly improved from 29.8, 42.2, and 78.4 preoperatively to 12.4, 11.2, and 13.2 at the final follow-up, respectively. Non-union was observed in one patient. No other complications were observed. CONCLUSIONS: Arthroscopy-assisted arthrodesis is a valuable procedure for thumb CMC osteoarthritis. However, the learning curve for this procedure must be overcome before the operative time can be shortened and successful bone union and satisfactory outcomes achieved.

Clinical outcomes following tibiotalocalcaneal arthrodesis with intramedullary nailing combined with partial fibulectomy and onlay bone graft.

INTRODUCTION: Although intramedullary nailing is a popular method for tibiotalocalcaneal arthrodesis, nonunion is one of the most commonly reported complications. This study aimed to evaluate the fusion rate, improvement in functional outcomes, and occurrence of complications in tibiotalocalcaneal arthrodesis using retrograde intramedullary nailing with partial fibulectomy and onlay bone graft technique. MATERIALS AND METHODS: Twenty-six consecutive patients using the proposed technique were retrospectively reviewed. For radiographic outcomes, the union rate, alignment, and any related complications were assessed. Functional outcomes were evaluated using the American Orthopedic Foot and Ankle Society hindfoot scale, Foot and Ankle Outcome Score, and visual analog scale, preoperatively and at the final follow-up. RESULTS: The mean follow-up period was 38.2 months. The tibiotalar joint achieved complete union in 80.8% at six months postoperatively, while all the cases achieved complete union at 12 months postoperatively. However, the subtalar joint achieved complete union in 26.9% at six months postoperatively, which gradually increased to 73.1% at 12 months postoperatively, and 80.8% at the final follow-up without revision surgery. A subgroup analysis showed there was a trend of higher subtalar fusion rate when an additional screw for the subtalar joint fixation was placed (86.7% vs. 54.5%). The functional outcomes significantly improved at the final follow-up. A few minor complications occurred, including surgical site infection, irritational symptoms, and metal failure; however, they eventually resolved. CONCLUSIONS: Our technique of tibiotalocalcaneal arthrodesis with partial fibulectomy and onlay bone grafting could be a good option where both the tibiotalar and subtalar joints need to be fused.

Defining the Structures at Risk and an Anatomical Safe Zone for Percutaneous Antegrade Subtalar Joint Fixation With a Single Screw: A Cadaveric Study.

Percutaneous antegrade (anterior to posterior) fixation for subtalar joint (STJ) arthrodesis offers various intraoperative and biomechanical advantages. Currently, the entry point for percutaneous antegrade STJ screw fixation is not clearly described and variable. To our knowledge, there are no publications that evaluate anatomic structures at risk or define an anatomically safe entry point for this fixation. The aim of this investigation was to define an anatomically safe and reproducible entry point for percutaneous antegrade STJ arthrodesis fixation, while also describing anatomic structures at risk when undertaking this method of fixation. We hypothesized that percutaneous single screw antegrade STJ fixation would encroach upon named anatomic structures in more than one cadaveric specimen. Ten cadaver limbs were used in this investigation. A percutaneous guidewire was inserted 5 mm lateral to the tibialis anterior tendon. The midpoint of the talar neck served as the sagittal plane starting point, as seen on the lateral fluoroscopic view. A cannulated 6.5-mm headed screw was inserted antegrade through the STJ into the calcaneus. Each specimen was dissected to assess the distance from the screw to nearby anatomic structures and distance from the tibialis anterior tendon to named structures. Our hypothesis was found to be incorrect, as 0/10 screws invaded neurovascular or tendinous structures. The dorsalis pedis artery and deep peroneal nerve were on average 12.1 ± 2.79 mm and 12.2 ± 2.82 mm lateral to the screw, respectively. These findings are clinically relevant and ultimately allow us to define an anatomic safe starting point for percutaneous antegrade STJ single screw fixation.

Operative Time, Cost, and Union Rate of Power Rasp Joint Preparation Versus Traditional Preparation in Arthrodesis of the Foot and Rearfoot.

Time spent in the operating room is valuable to both surgeons and patients. One of the biggest rate-limiting factors when it comes to arthrodesis procedures of the foot and ankle is cartilage removal and joint preparation. Power instrumentation in joint preparation provides an avenue to decrease joint preparation time, thus decreasing operating room time and costs. Arthrodesis of 47 joints (n) from 27 patients were included. Power rasp joint preparation in 26 joints was compared to traditional osteotome and curette joint preparation in 21 joints in both time (seconds), cost (total operating room time cost per minute), and union rate. The overall mean joint preparation time using power rasp for the subtalar joint was 268.3 seconds, talonavicular joint 212.3 seconds, calcaneocuboid joint 142.6 seconds, 1st TMT 107.2 seconds. Mean joint preparation time using traditional method for subtalar joint 509.8 seconds, talonavicular joint 393.0 seconds, calcaneocuboid joint 400.0 seconds, 1st TMT 319.6 seconds. Mean cost of joint preparation using power rasp for subtalar joint $165.47, talonavicular joint $130.89, calcaneocuboid joint $87.94, 1st TMT $66.11. Mean cost of joint preparation using traditional techniques for subtalar joint $314.34, talonavicular joint $242.35, calcaneocuboid joint $246.67, 1st TMT $197.33. Overall union rate was 98% (1 asymptomatic non-union). Increasing efficiency in the operating room is vital to every surgeon's practice. Power rasp joint preparation is a viable option to increase efficiency and decrease operative time, this study shows no statistically significant differences in union rate, with comparable rates to existing literature.

Immediate Weightbearing Following First Metatarsal Phalangeal Joint Arthrodesis With 2 Nickel Titanium Alloy Staples.

The use of staples has been shown to be a reasonable fixation technique to achieve stability of a first MTPJ arthrodesis. Although it has been shown to be a weaker construct than crossed screws or plate and screw combinations, their ease of insertion, low profile, and stability make them a desirable choice for first MTPJ arthrodesis fixation. However, because of this relative weakness, the question remains whether immediate weightbearing when using staples is advisable. The aim of this study is to determine whether the use of 2 nickel-titanium alloy (NITINOL) staples, placed at 90 degrees to one another is a stable enough construct to support full, immediate weightbearing following first MTPJ arthrodesis. We performed a retrospective chart review of patients undergoing first MTPJ arthrodesis by a single surgeon utilizing 2 NITINOL staples placed at 90 degrees to one another. Patients were allowed to be fully weightbearing immediately postoperatively. Forty-seven of 50 (94%) patients achieved complete radiologic consolidation of fusion at 12 weeks, with only 3 requiring revision surgery for nonunion. All of the patients requiring revision surgery for nonunion, had preoperative diagnosis of hallux abducto valgus. We concluded that the use of 2 NITINOL staples placed at 90 degrees to one another is a viable option for first MTPJ arthrodesis, and immediate weightbearing does not increase rate of nonunion or incidence of revision surgery when compared to other fixation techniques.

Characteristics of Nonunion After Arthroscopic Ankle Arthrodesis: A Multicenter Retrospective Cohort Study.

Nonunion is a major complication of arthroscopic ankle arthrodesis. However, the characteristics and risk factors of nonunion are not well understood. This retrospective multicenter observational study aimed to clarify the characteristics of nonunion after arthroscopic ankle arthrodesis. We included 154 patients who underwent arthroscopic ankle arthrodesis at any 1 of 5 institutions. Patients were divided into 2 groups: union and nonunion, and the groups were compared. Age, sex, body mass index, diabetes, smoking, corticosteroid use, diagnosis, treatment information, treatment protocol, radiographic evaluation, and patient-reported outcomes were recorded and analyzed. On radiographs, bony union was observed in 142 ankles (91.0%) but not in 12 ankles (9.0%). Postoperative radiographic tibial bony gap (mm) was significantly larger in the nonunion group (medial = 1.98, center = 1.65, anterior = 2.21, middle = 1.72, posterior = 3.01) than in the union group (medial = 1.35, center = 1.13, anterior = 1.28, middle = 1.03, posterior = 2.03). Furthermore, the visual analog score (VAS) of pain and pain-related self-administered foot evaluation questionnaire (SAFE-Q) subscale score significantly worsened in the nonunion group (VAS = 3.83, SAFE-Q subscale score = 69.8) compared to that in the union group (VAS = 1.35, SAFE-Q subscale score = 76.6). A larger radiographic tibiotalar bony gap was observed in the nonunion group. Other measurement outcomes were not associated with nonunion. Additionally, patient-reported outcomes markedly worsened in the nonunion group.

Predictive Factors of Postoperative Pain in Patients With Tibiotalocalcaneal Arthrodesis With an Intramedullary Nail: A Retrospective Review.

Tibiotalocalcaneal arthrodesis has been shown in literature to have good results in regards to low complication rates and deformity correction. While previous studies have investigated functional outcomes and complication rates, no large-scale studies have looked at pain outcomes. The present study performed a retrospective review of 154 extremities to analyze how a patient's comorbidities and characteristics influence pain outcomes following a tibiotalocalcaneal arthrodesis. The present study found an average change of pain from 7.1 to 3.0 in at least a 6 month follow up. We found that a diagnosis of chronic pain and tobacco use had statistically significant less pain improvement compared to patients without chronic pain or current tobacco use. We determined no statistically significant difference in pain outcomes for patients with or without Charcot deformity. Lastly, we found that with older patients there was more pain improvement observed. We physicians can educate current tobacco users of the improved pain outcomes with tobacco cessation prior to surgery. We recommend a multidisciplinary approach for pain in patients with a pre-operative diagnosis of chronic pain and to educate patients on realistic postoperative pain outcomes.

Patient Reported Outcomes Following Triple Arthrodesis for Adult Acquired Flat Foot Deformity: Minimum Two Year Follow Up.

The aim of this study is to analyze patient-reported outcomes following this procedure as well as any demographics that may confer prognostic capability. A retrospective analysis was conducted of patients who underwent Triple Arthrodesis at our facility from 2014-2021. Patients were selected if they underwent an isolated triple arthrodesis. All cases included either a gastrocnemius recession versus a percutaneous tendo-achilles lengthening depending on the patient's Silverskiold examination. The electronic medical record was utilized to collect basic patient demographics, previous foot and ankle surgeries, hardware failures, additional procedures, and surgical complications. To evaluate outcomes, we compared patient reported outcomes measurement information system (PROMIS) survey scores with the general population and preoperative versus postoperative visual analog scale (VAS) scores. Foot function index (FFI) scores and scores were utilized as a validation tool for our results. A total of 132 patients met the criteria for our study with a total of 50 participants completing the PROMIS and FFI surveys. The average time point at which the outcomes were collected was 5.50 y postoperatively, ranging from 1.65 to 7.57 y. The average PROMIS physical function was 38.35, pain interference was 61.52, and depression was 49.82 for this population. The mean FFI scores were 58.56 for pain, 60.07 for disability, and 48.07 for activity limitation. There was a significant decrease in preoperative and postoperative VAS scores from 5.4 to 2.55 (p < .001). Three patients experienced wound complications related to decreased sensation. Our results indicated that only PROMIS depression scores were within one standard deviation of the population mean following a triple arthrodesis procedure. PROMIS physical function and pain interference were both outside of one standard deviation for the population.

Tension Side Fixation for Lapidus Arthrodesis: A Retrospective Analysis.

Moderate to severe hallux valgus deformity often requires a Lapidus procedure (first-tarsometatarsal arthrodesis). Traditional methods include a dorsal approach with dorsal or medial fixation. However, studies demonstrate plantar/tension-side fixation, provides superior load to failure and fixation strength. This could improve outcomes, address comorbidities, and accelerate postoperative protocols; however, a paucity exists for patient outcomes in the literature regarding tension-side-fixation. The purpose of this study is to report the outcomes for tension-side Lapidus fixation. A retrospective analysis was performed of 81 patients who underwent tension-side-fixation Lapidus. Data collection consisted of: time to weight-bear, time to return to regular shoegear, hardware removal rate, revision rate, recurrence rate, relative metatarsal shortening, and nonunion rates. Mean patient age was 44 years old (range: 16-82). There were 65 females, and 16 males. The average time to weightbearing was 10.4 days. Time to return to regular shoegear was a mean of 6 weeks (ranging 2-10 weeks). Hardware removal rate was 1.2%. The recurrence rate was 8.6% (7 of 81 patients) and 5 of those 7 patients experienced recurrence before frontal-plane-correction was adopted by the surgeon. The revision rate was 0% and despite 8.6% recurrence, no patients were dissatisfied or requested a revisional procedure. The first-metatarsal shortening was a mean of 0.42 mm. The complications were as follows: 7% superficial dehiscence, 1.2% superficial wound infection, 0% deep infection, and 1.2% asymptomatic nonunion. This study suggests tension-side-fixation for Lapidus arthrodesis may allow for safe early return to weightbearing, early return to regular shoegear, low hardware removal rate, low revision rate, low metatarsal shortening, and low nonunion rate.

Morbidity Associated With Distal Tibial Autograft Harvest.

Distal tibial autograft harvesting has been studied in the past, but morbidity at the level of the donor site is unclear. The purpose of this retrospective review is to assess morbidity in distal tibial autograft harvesting associated with foot and ankle arthrodesis procedures. A retrospective analysis was performed utilizing patients treated in the last 13 years at a large, multicenter, academic, tertiary referral, research institution. Included patients were between the ages of 18 and 80 years old. One-hundred and seven patients (39 male; 68 female) underwent ipsilateral distal tibial bone graft (n = 110) harvesting to augment the index procedure. Patients were followed for an average of 11.2 months after surgery (Range: 1-73 months). The incidence rate of distal tibial stress fractures was 4.5%, with an overall postoperative complication rate of 8.2%. Overall, low complication rates associated with distal tibial autograft harvesting were found, supporting the use of the distal tibia as an appropriate site for autograft harvesting in foot and ankle surgery.

Isolated Subtalar Repositional Arthrodesis Compared With Triple Arthrodesis for the Treatment of Progressive Collapsing Foot Deformity.

The optimal extent of arthrodesis for severe and rigid progressive collapsing foot deformity is controversial. Traditionally, triple arthrodesis has been recommended; however, good results have been reported using subtalar arthrodesis only. We compared the results of triple arthrodesis and isolated subtalar repositional arthrodesis. A total of 22 symptomatic feet were evaluated retrospectively. Isolated subtalar repositional arthrodesis was performed in 13 cases (the subtalar group) and double or triple arthrodesis in 9 cases (the triple group). Various radiographic variables for assessing flatfoot and osteoarthritic changes in ankle and tarsal joints were measured and compared between the 2 groups at 3 time points: preoperatively, 3 months postoperatively, and 4 y postoperatively. Additionally, we analyzed various factors that affect postoperative valgus talar tilt in the ankle joint, which has been associated with poor prognosis. There were no differences in preoperative demographic data and the severity of the disease between the 2 groups; both groups showed improvement in radiographic parameters postoperatively compared with preoperative results. With the numbers available, no significant differences could be detected in postoperative radiographic measurements between the 2 groups. Of all the variables analyzed, postoperative hindfoot alignment angle was associated with postoperative talar tilt development. Additionally, postoperative talar tilt was observed more in triple group than in subtalar group. In conclusion, isolated subtalar repositional arthrodesis is an effective procedure to correct advanced progressive collapsing foot deformity. In addition, Chorpart joint arthrodesis with improper position can cause valgus talar tilt in the ankle joint.
