Though research exists regarding calcaneal fractures, the treatment approach for displaced intra-articular calcaneal fractures (DIACF) remains controversial. The most common approach, the extensile lateral approach (ELA), for the treatment of DIACFs has high rates of wound complications reported. In contrast, the sinus tarsi approach (STA) is becoming more popular due to its minimally invasive technique. The objective of this retrospective study is to investigate the incidence of wound complications in high-risk patients with DIACF following operative fixation via the STA.Following IRB approval, a retrospective chart review was performed between 2007 and 2013 to assess high-risk patients for the presence of wound complications, including deep infections and delayed wound healing, following the use of STA for the management of DIACF's (n = 36). Demographics, risk factors, and secondary outcomes such as time to surgery were recorded.Of the 36 high-risk patients included in our study, seven had post-operative complications following operative fixation via the STA. Specifically, four patients had delayed wound healing, and three developed deep infections. Time to surgery had the greatest negative effect on postoperative complications and was influenced by age, sex, and the presence of a concomitant injury.In conclusion, this study demonstrates that the STA is a viable option for high-risk patients with displaced intra-articular fractures. Additionally, time to surgery should be minimized, when possible, to reduce risks of post-operative complications, including infections and delayed wound healing.

Introduction In the setting of pathologic fractures or impending fractures of the femur, intramedullary nailing or hemiarthroplasty are the common surgical procedures indicated. Traditional teaching has stressed the importance of protecting the entire femur, and thus, it is common for these fractures to be treated with long nails or stems. Recent literature has begun to investigate whether this school of thought is valid and may challenge the perceived need for protection of the entire femur. The purpose of our study was to determine the incidence of ipsilateral distal femoral metastases after the treatment of proximal femoral metastases. Methods A retrospective chart review was performed that identified 66 patients who presented with completed or impending pathologic fractures of the proximal femur who then underwent either intramedullary nailing or hemiarthroplasty for surgical stabilization. Plain radiographs, in conjunction with CT, MRI, or positron emission tomography-CT when available, were used to determine whether there was disease progression and/or distal metastasis in the femur. Results There was one patient (1.5%) in this series who developed distal femoral metastasis after hemiarthroplasty from metastatic breast carcinoma. There were three patients (4.54%) with local progression of the disease. No patient required further intervention, and there were no cases of hardware failure or periprosthetic fracture after prophylactic fixation. Discussion Our findings show that there is an extremely low likelihood of developing distal femoral metastases when isolated proximal femoral metastases are present and thus protecting the entire femur may not be necessary in this clinical scenario. Level of evidence IV, therapeutic study.

The purpose of this study was (1) to determine how much emphasis is placed on the Personal Statement (PS) by program directors (PDs) and (2) to gain a better understanding of what factors within the PS are considered most important to PDs. An anonymous survey was distributed to PDs at allopathic orthopaedic residency programs in the United States using Survey Monkey (San Mateo, CA). Survey responses were received from 51 of 152 (34%) PDs. Forty-five (88.2%) identified as male, five (9.8%) identified as female, and one (1.9%) chose not to disclose. PDs reported the PS was of average importance, with an average score of 2.82 (range,1-4). Although the PS is still given consideration as part of the overall orthopaedic surgery residency application process, it does not play a major role in determining which applicants will be invited for an interview or how they will be ranked. (Journal of Surgical Orthopaedic Advances 31(2):090-095, 2022).

Radiologists work in conjunction with orthopedic surgeons to evaluate the progression of bone healing and identify potential problems during bone reconstruction. Accurate evaluation and identification of healing progression or complications are critical to optimizing successful patient outcomes with either distraction osteogenesis or bone grafting. Therefore, radiologists must understand the fundamental concepts behind these surgical reconstructive techniques in order to provide accurate postoperative radiographic assessments. The cases and discussion within this review aim to provide this foundational knowledge.

Avulsion fractures of the perilunate ligaments occur in isolation, and multiple fractures are typically not seen in the same carpus. We present a case of a 15-year-old male who injured his wrist during football practice. He presented without wrist dislocation or deformity. Radiographs demonstrated avulsion fractures to the proximal pole of the scaphoid and proximal radial aspect of the triquetrum. The patient was immobilized with an upper extremity thumb spica cast; however, there was persistent non-union of both fractured segments. Magnetic resonance imaging confirmed avulsions at the site of the scapholunate and lunotriquetral ligaments, with both ligaments relatively intact. At the last follow-up, one year after the initial injury, the patient had a normal clinical exam, with no pain and full wrist range of motion despite fracture non-union at both locations. This is a unique injury with an unclear mechanism and complicated management.

Orthopaedic surgery is one of the most competitive specialties in the residency match. The personal statement (PS) is one component of the application. The significance of the PS to orthopaedic surgery residency applicants is unknown. This study evaluates applicant perceptions of the PS. Applicants to two separate United States orthopaedic residency programs for the 2019-2020 cycle were invited to participate. Survey was distributed via email. Twenty-one percent (204/978) of applicants completed the survey. Most were men (157/204, 77%), and most (125/204, 61%) spent up to 15 hours writing their PS. Many [79.4% (162/204)] believed the PS should continue to be included in the application. Women always edited their PS, while 7.0% (11/ 157) of men did not use any editors. Applicants believe the PS is valuable. The PS is time consuming but allows applicants to communicate details that otherwise may not be included in their application.

Context Management of isolated grade III medial collateral ligament injuries is controversial, as both nonoperative and operative management can result in return to play. However, operative management is recommended in elite athletes who have a grade III injury with distal avulsion. Objective We present a standardized rehabilitation protocol in a case series of 7 National Collegiate Athletic Association Division I American football athletes who sustained grade III distal medial collateral ligament tears that were repaired operatively, with emphasis on return to play. Results Median time to surgery was 4 days (range = 2–67 days). Median time from surgery to noncontact drills was 120.5 days (range = 104–168 days), and median time from surgery to full-contact sport was 181 days (range = 139–204 days). All athletes returned to play at their preinjury level of competition. Conclusions Our study highlighted how operative management with a standardized rehabilitation protocol can be applied to Division I football players and result in safe return to play.

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.

Abstract

Category: Hindfoot; Ankle Introduction/Purpose: Achilles Tendon (AT) rupture is the most common tendon rupture in the lower extremity with an incidence of 2.1 AT ruptures per 100,000 person years. Due to the non-emergent nature of this injury, a delay in presentation may occur leading to delays in diagnosis and treatment; which may alter both nonoperative and operative management. Health insurance status may directly impact time to presentation for many patients. To our knowledge, no study has evaluated the effect of insurance status on delay in diagnosis and treatment of AT rupture. Methods: From December 2013 to December 2018, 89 patients with AT ruptures who underwent surgical management were identified by CPT code in a dual-institution retrospective chart analysis. Demographic and injury-specific data were obtained with attention to the date of injury, date of diagnosis, location of initial presentation (clinic vs. emergency room), and number of medical visits. A univariate two tail t test was used to compare various groups. Statistical significance was set at p < 0.05 to determine the effects of insurance type on the time to diagnosis and treatment of acute AT ruptures. Results: When compared to adequately insured patients (private and Medicare), underinsured patients (uninsured and Medicaid) experienced a significantly greater time from the date of: injury to first clinic visit (14.5 days versus 5.2 days, p < 0.001), first clinic visit to surgery (34.6 days versus 4.8 days, p < 0.002), injury to surgery date (48.9 days versus 9.8 days, p < 0.001), initial presentation to when magnetic resonance imaging (MRI) was obtained (48.1 days versus 1.9 days, p < 0.002), and initial presentation to diagnosis (22.8 days versus 1.71 days, p < 0.029). Conclusion: Disparities in access to care are intimately related to insurance status. Uninsured and medicaid patients are subject to institutional delays and decreased access to care when compared to patients with private insurance. Under and uninsured patients are significantly more likely to present to the emergency department for their initial visit, potentially resulting in increased healthcare costs. Emergency department visits as well as difficulty in obtaining an appointment with an orthopedic surgeon may directly contribute to delay in diagnosis.

Background Medial epicondylitis and lateral epicondylitis are among the most common elbow pathologies affecting people aged between 40 and 50 years. Although epicondylitis is often a self-limiting condition that improves with conservative treatment, the condition can be difficult to eradicate. The purpose of this study was to compare the effectiveness of platelet-rich plasma (PRP) injections and ultrasound-guided percutaneous tenotomy (Tenex) for the treatment of medial or lateral epicondylitis. Our hypothesis was that the Tenex procedure would not be inferior to PRP injections in the treatment of medial or lateral epicondylitis. Methods In this retrospective review, 62 of 75 patients were available for contact via phone and e-mail to complete post-procedure patient-reported outcome surveys. Subjective assessment of pain and function included a visual analog scale for pain; the Quick Disabilities of the Arm, Shoulder and Hand questionnaire; and the EuroQol-5D questionnaire. The inclusion criteria included age of 18 years or older and previous failure of nonoperative treatment. Results The average ages in the PRP and Tenex groups were 47 years and 51 years, respectively. The PRP cohort (n = 32) included 10 female and 22 male patients, whereas the Tenex cohort (n = 30) included 12 female and 18 male patients. The PRP and Tenex groups both demonstrated clinical and statistical improvement in visual analog scale pain scores; Quick Disabilities of the Arm, Shoulder and Hand scores; and EuroQol-5D scores. No statistically significant difference was found between the 2 treatment modalities. Conclusion The PRP and Tenex procedures were both successful in producing clinically and statistically significant improvements in pain, function, and quality of life.

Background: The purpose of this study was to investigate the relationship between insurance status and patient-reported pain both before and after upper extremity surgical procedures. We hypothesized that patients with Medicaid payer status would report higher levels of pre- and postoperative pain and report less postoperative pain relief. Methods: In all, 376 patients who underwent upper extremity procedures by a single surgeon at an academic ambulatory surgery center were identified. Patient information, including insurance status and Visual Analog Scale pain score (VAS-pain) at baseline, 2 weeks, and 1, 3, and 6 months, were collected. VAS-pain scores were compared with t-tests and linear regression. Results: Preoperatively and at 2-week, 1-month, and 3-month follow-up, Medicaid patients reported statistically significant higher pain levels than patients with Private insurance, finding a mean adjusted increase of 0.51 preoperatively, 0.39 at 1 month, and 0.79 at 3 months. Preoperatively and at 3-month follow-up, Medicaid patients reported statistically significant higher pain than patients with Medicare, finding increases in VAS-pain of 0.99 preoperatively and 0.94 at 3 months. There was no difference in pain improvement between any insurance types at any time point (all P values > .05). Conclusions: Patients with Medicaid report higher levels of preoperative pain and early postoperative pain, but reported the same improvement in pain as patients with other types of insurance. As healthcare systems are becoming increasingly dependent on patient-reported outcomes, including pain, it is important to consider that differences may exist in subjective pain depending on insurance status.

Limb salvage surgery refers to orthopaedic procedures designed to resect tumors and reconstruct limbs. Improvements in managing malignant bone lesions have led to a dramatic shift in limb salvage procedures. Orthopaedic surgeons now employ four main reconstructive procedures: endoprosthesis, autograft, bulk allograft, and allograft prosthetic composite. While each approach has its advantages, each technique is associated with complications. Furthermore, knowledge of procedure specific imaging findings can lead to earlier complication diagnosis and improved clinical outcomes. The aim of this article is to review leading reconstructive options available for limb salvage surgery and present a case series illustrating the associated complications.

Background: Hammertoe deformities are the most common lesser toe deformity. To date, no studies have looked at outcomes of operative management in the geriatric population, which may be at greater risk for complications or functional compromise because of comorbidities. Methods: Data on 58 patients undergoing operative correction of hammertoe deformities were prospectively collected. Clinical outcomes were assessed using preoperative and postoperative visual analogue scale (VAS) and Short Form Health Survey (SF-36) scores with a minimum of 6-month follow-up. Patients were divided into 2 groups on the basis of age at the time of surgery: younger than 65 and 65 and older. Complication rates and mean VAS and SF-36 improvement were compared. Forty-seven patients met inclusion criteria (7 men, 40 women), with 26 patients (37 toes) in the younger cohort and 21 patients (39 toes) in the older cohort. Results: Overall, patients demonstrated significant improvement from baseline to 6 and 12 months postoperatively in VAS ( P < .001 and P < .001) and SF-36 ( P < .001 and P < .001) scores. Mean improvement in VAS and SF-36 scores was not significantly different between the groups at 6 and 12 months postoperatively. Complications occurred in 13.5% and 10.3% of patients in the younger and older cohorts, respectively. Conclusions: Outcomes of operative correction of hammertoe deformities in older patients were similar to outcomes in younger patients after greater than 6 months of follow-up. Overall improvement in VAS and SF-36 was statistically significant for both cohorts. There was no associated increase in complications for older patients. Level of Evidence: Level, III comparative series.

Insertional Achilles tendinopathy (IAT) is a frequent cause of posterior heel pain and is often associated with Haglund’s deformity. Surgical correction for refractory cases of IAT has been well studied; however, the method of tendon fixation to bone in these procedures remains controversial, and to date, no standard technique has been identified for tendon fixation in these surgeries. Often, after Haglund’s resection, there is large exposed cancellous surface for Achilles reattachment, which may require unique fixation to optimize outcomes. Previous studies have consistently demonstrated improved patient outcomes after Achilles tendon reconstruction with early rehabilitation with protected weight bearing, evidencing the need for a strong and stable anchoring of the Achilles tendon that allows early weight bearing without tendon morbidity. In this report, we highlight the design, biomechanics, and surgical technique of Achilles tendon reconstruction with Haglund’s deformity using a novel technique that utilizes ultrasonic energy to liquefy the suture anchor, allowing it to incorporate into surrounding bone. Biomechanical studies have demonstrated superior strength of the suture anchor utilizing this novel technique as compared with prior techniques. However, future research is needed to ensure that outcomes of this technique are favorable when compared with outcomes using traditional suture anchoring methods.

Background: Management of spine fractures has advanced considerably even over the past decade. A review of the current and historical literature can lead to a better appreciation of current management protocols. This is the first comprehensive review of the most influential articles related to spine fracture management. The purpose of this study is to identify and analyze the 100 most cited publications in spine fracture management. Methods: Using the Clarivate Analytics Web of Science, search phrases were used to identify publications pertaining to spine fractures (110,809 publications). The 100 most cited articles were isolated. The frequency of citations, year of publication, country of origin, journal of publication, level-of-evidence (LOE), article type, and contributing authors/institutions were recorded. We also highlighted the ten most cited articles (per year) from the past decade. Results: The publications included ranged from 1953–2010, with the majority published between 2000–2009 (n=41). Total citations ranged from 154 to 1,076. A LOE of IV had the plurality at 36%. The most cited article was “The 3 Column Spine and Its Significance in The Classification of Acute Thoracolumbar Spinal-Injuries” ( Spine 1983) by F Denis. The majority of papers originated in the United States (n=65), and the highest number were published in Spine (n=27). Osteoporotic fractures were the specific topic in 34 publications. In the past decade, the article with the most citations/year was “A Randomized Trial of Vertebroplasty for Osteoporotic Spinal Fractures” by DF Kalmes in 2009. Conclusions: Despite less time for citation than other decades, the 2000s contain the plurality of the influential publications. This may indicate that some of the most important changes to spine fracture management pertain to improved imaging modalities and surgical technologies. This review provides a guide for a comprehensive understanding of the historical and current literature pertaining to spine fracture management.

Case: A 45 year old male, >1 year status post left elbow lateral debridement for lateral epicondylitis, presented with a two week history of a progressive, tender mass on the lateral aspect of his left elbow. MRI showed evidence of a defect in the joint capsule, consistent with the formation of a seroma. The patient underwent revision of the left lateral epicondyle debridement with ECRL/EDC tendon repair and capsular reconstruction. Conclusion: Tendon repair and capsular reconstruction is an effective and successful method for the treatment of a seroma caused by leakage of joint fluid after lateral epicondylar debridement.

Background: In the currently published literature, a higher risk for developing arthrofibrosis after anterior cruciate ligament (ACL) reconstruction has been reported for female patients, adolescents, early surgery or concomitant procedures, and the use of a patellar tendon autograft. There is a lack of evidence regarding other graft choices or factors. Hypothesis: Multiple risk factors will play a significant role in the development of arthrofibrosis after ACL reconstruction. Specifically, we hypothesized that the risk of manipulation under anesthesia (MUA) and/or lysis of adhesions (LOA) would be affected by graft choice and patient demographic factors. Study Design: Case-control study; Level of evidence, 3. Methods: The charts of all patients who underwent ACL reconstruction over a 10-year period at a single academic institution were queried from an electronic medical record database and reviewed at a minimum of 6 months after ACL reconstruction, with the collection of demographic and surgical data. The relative risk for undergoing MUA and/or LOA was calculated for each analyzed risk factor. Results: A total of 2424 ACL reconstructions were included, with a chart review at a mean of 56.7 months after surgery (range, 7.6-124.0 months). The rate of MUA and/or LOA for arthrofibrosis was 4.5%. A statistically significantly increased relative risk was found for infection (5.45), hematoma requiring evacuation (3.55), ACL reconstruction with meniscal repair (2.83), use of a quadriceps tendon autograft (2.68), age 25 years (0.34), and use of a tibialis anterior allograft (0.36). In the multivariate regression model, the use of a quadriceps tendon autograft (P = .00007), infection (P = .00126), and concomitant meniscal repair (P = .00194) were independent risk factors, whereas revision ACL reconstruction (P = .0024) was an independent protective factor. Conclusion: Graft type, infection, concomitant meniscal repair, and primary reconstruction are significant risk factors for undergoing MUA or LOA after ACL reconstruction.

Background: Current techniques for fixation of proximal pole scaphoid fractures utilize antegrade fixation via a dorsal approach endangering the delicate vascular supply of the dorsal scaphoid. Volar and dorsal approaches demonstrate equivalent clinical outcomes in scaphoid wrist fractures, but no study has evaluated the biomechanical strength for fractures of the proximal pole. This study compares biomechanical strength of antegrade and retrograde fixation for fractures of the proximal pole of the scaphoid. Methods: A simulated proximal pole scaphoid fracture was produced in 22 matched cadaveric scaphoids, which were then assigned randomly to either antegrade or retrograde fixation with a cannulated headless compression screw. Cyclic loading and load to failure testing were performed and screw length, number of cycles, and maximum load sustained were recorded. Results: There were no significant differences in average screw length (25.5 mm vs 25.6 mm, P = .934), average number of cyclic loading cycles (3738 vs 3847, P = .552), average load to failure (348 N vs 371 N, P = .357), and number of catastrophic failures observed between the antegrade and retrograde fixation groups (3 in each). Practical equivalence between the 2 groups was calculated and the 2 groups were demonstrated to be practically equivalent (upper threshold P = .010). Conclusions: For this model of proximal pole scaphoid wrist fractures, antegrade and retrograde screw configuration have been proven to be equivalent in terms of biomechanical strength. With further clinical study, we hope surgeons will be able to make their decision for fixation technique based on approaches to bone grafting, concern for tenuous blood supply, and surgeon preference without fear of poor biomechanical properties.

Background Context There is growing concern that the microbial profile of surgical site infection (SSI) in the setting of prophylactic vancomycin powder may favor more resistant and uncommon organisms. Purpose To demonstrate the impact of prophylactic intraoperative vancomycin powder on microbial profile, antibiotic regimen, length of stay (LOS), and reoperation rate in spine surgical site infection. Study Design and/or Setting Retrospective cohort study. Patient Sample: the study included 115 postoperative spine patients who were required to return to the operating room for SSI. Outcome Measures The outcome measures were microbial profile, reoperation rate, antibiotic regimen, and LOS for patients with postoperative spine infection who either did (treated) or did not (untreated) receive prophylactic vancomycin powder during their index procedure. Methods A retrospective review of patients who underwent posterior thoracic and/or lumbar spine surgery between 2010 and 2017 was conducted. Those undergoing surgical treatment of SSI were identified, and patients were divided into two groups - those who were treated with intraoperative vancomycin (treated) and those who were not (untreated). The organism profile for each group was compared. The average LOS, reoperation rate, and number of patients requiring more than 1 antibiotic were calculated for each patient in both groups. Results There were 5,909 procedures performed. One hundred and fifteen SSIs were identified, resulting in a 1.9% infection rate. Prophylactic vancomycin powder was used in the index procedure for 42 of those cases. 23.8% of cultures in the vancomycin group were polymicrobial and 16.7% were gram-negative compared with 9.6% (p=0.039) and 4.1% (p=0.021) in the untreated group, respectively. In the vancomycin-treated group, 26.1% of patients underwent repeat irrigation and debridement compared with 38.4% in the untreated group (p=0.184). The percentage of patients in the treatment and untreated group who required more than 1 antibiotic was 26.0% and 26.1%, respectively (p=0.984). Mean LOS in the treatment group was 8.0 versus 7.9 for the untreated group (p=0.945) Conclusions In this series, vancomycin powder was associated with a higher prevalence of gram-negative and polymicrobial organisms in patients that ultimately developed postoperative SSI. However, this did not adversely affect the need for multiple reoperations, antibiotic regimen, or LOS for these patients.

Background: Small olecranon fractures present a significant challenge for fixation, which has resulted in development of plates with proximal extension. Olecranon-specific plates with proximal extensions are widely thought to offer superior fixation of small proximal fragments but have distinct disadvantages: larger dissection, increased hardware prominence, and the increased possibility of impingement. Previous biomechanical studies of olecranon fracture fixation have compared methods of fracture fixation, but to date there have been no studies defining olecranon plate fixation strength for standard versus extended olecranon plates. The purpose of this study is to evaluate the biomechanical utility of the extended plate for treatment of olecranon fractures. Methods: Sixteen matched pairs of fresh-frozen human cadaveric elbows were used. Of the 16, 8 matched pairs received a transverse osteotomy including 25% and 8 including 50% of the articular surface on the proximal fragment. One elbow from each pair was randomly assigned to a standard-length plate, and the other elbow in the pair received the extended-length plate, for fixation of the fracture. The ulnae were cyclically loaded and subsequently loaded to failure, with ultimate load, number of cycles, and gap formation recorded. Results: There was no statistically significant difference between the standard and extended fixation plates in simple transverse fractures at either 25% or 50% from the proximal most portion of the articular surface of the olecranon. Conclusion: Standard fixation plates are sufficient for the fixation of small transverse fractures, but caution should be utilized particularly with comminution and nontransverse fracture patterns.

Introduction. On-call orthopedic clinicians have long speculated that daily consult volume is closely correlated with weather. While prior studies have demonstrated a relationship between weather and certain fracture types, the effect of weather on total orthopaedic consult volume has not yet been examined. The aim of this study was to investigate this relationship.Methods. We retrospectively reviewed orthopaedic consult data from 405 consecutive days at an urban, level one trauma center. The number, mechanism of injury, and type of consult were collected, along with daily weather data (temperature, wind, and precipitation). Statistical analysis was then performed to determine the relationship between weather and orthopaedic trauma consults.Results. A total of 4543 consults were received during the study period. There was a significant difference in total number of consults between months of the year (pConclusion. Weather parameters, specifically average temperature and precipitation, were found to be associated with daily orthopedic consult type and volume. Additionally, consult volume varies significantly between months of the year. Because trauma centers are often resource scarce, this is an important relationship to understand for proper resource allocation.

Category: Lesser Toes Introduction/Purpose: Hammertoe deformities are common, often painful deformities of the lesser foot and are known to severely affect daily activities. When patients seek surgical management, x-rays are utilized for diagnosis, evaluation for surgical candidacy, and selection of the operative technique. Postoperatively, radiographs are retaken to assess bone health, healing status, and alignment. Despite the frequent use of radiographs pre- and post-operatively, radiographic results are not necessarily indicative of clinical presentation or surgical outcomes. The aim of this study is to identify specific radiographic parameters that are predictive of improved pain and function after surgical correction of hammertoe deformity. Methods: Prospectively collected data was reviewed on 51 consecutive patients who underwent operative correction of hammertoe deformity. Patient demographics, comorbidities, and post-surgical complications were recorded from their electronic medical records. Clinical outcomes were assessed utilizing preoperative and postoperative Visual Analogue Scale (VAS) and Short Form Health Survey Physical Component (SF-36 PCS) scores with a minimum of six-month follow-up. Radiographs were scored by a foot & ankle fellowship-trained orthopaedic surgeon to assess preoperative severity, postoperative joint fusion, and both pre- and postoperative joint instability and arthritis. Data was examined using a multivariable analysis. Results: Preoperatively, 15.7% (8/51) of patients had a deformity classified radiographically as mild, 37.3% (19/51) as moderate, and 47.1% (24/51) as severe. Additionally, 60.8% (31/51) had joint instability, 17.7% (9/51) had joint dislocation, and 7.8% (4/51) had joint arthritis. Postoperatively, 74.5% had PIP joint fusion, 35.3% (18/51) had joint arthritis, and 9.8% (5/51) had joint instability. A significant association was found between PIP joint fusion and improved SF-36 PCS scores (p=.004). Preoperative anticoagulant therapy was associated with reduced rates of PIP joint fusion (p=0.02). There was no association found between the other demographic or radiographic parameters, and no parameters were associated with improvement in VAS scores. Conclusion: After undergoing surgical correction of hammertoe deformity, postoperative PIP joint fusion was the only variable determined to be indicative of improved physical function. However, pre- and postoperative metatarsophalangeal joint arthritis nor instability was predictive of outcomes. This work informs foot & ankle specialists that healing of the PIP joint is critical to successful hammertoe surgery.
