Background: Nail excisions are indicated for onychocryptosis and nail spicules. They are technically demanding and require a refined skill set. We aimed to characterize practice patterns of US providers performing nail excisions.

Methods: We conducted a retrospective analysis of Medicare provider use and payment data, part D, for all claims of partial or complete nail/nail matrix excision with/without nail plate removal/destruction (current procedural terminology code 11750). High performers were defined as providers performing annual nail excisions 2 standard deviations above the mean. We analyzed demographic risk factors for nail excision high performers, including practice location, years of experience, household median income, practice type, and provider gender. Statistical analysis was conducted in SAS v9.4, with values of P < .05 considered statistically significant.

Results: Providers (n = 32,279) and high performers (n = 942) performed mean 34.7 and 173 nail excisions annually. Unsurprisingly, podiatrists constituted 99.7% of all nail excision performers. Providers in the South versus Midwest and Northeast were more often nail excision high performers (odds ratio [OR], 1.95; P < .0001, and OR, 1.46; P < .0001). Solo versus group practitioners were more likely, respectively, to be nail excision high performers (OR, 2.15; P < .0001). With linear regression analysis, for every 10-year increase in years of provider experience, there was an increase of 1.2 nail excisions annually per provider (P < .0001). For every $100,000 increase in household median income of practice location, there was a decrease of 9.9 nail excisions annually per provider.

Conclusions: Southern podiatrists, podiatrists with more years of experience, solo practitioners, and those practicing in regions with lower household median incomes were more likely to perform higher numbers of nail excisions. Identifying performance trends among podiatrists can help podiatrists understand how their performance of nail excisions compares to other podiatrists across the country.

Background: Surgical treatment for Freiberg disease (also known as avascular necrosis of the metatarsal head) has not been completely defined. This retrospective study evaluated short-term outcomes after arthroscopic treatment of Freiberg disease.

Methods: From 2015 to 2019, 13 patients (15 feet) diagnosed as having Freiberg disease were enrolled for arthroscopic surgery. Feet were divided based on the Smillie classification system (two with stage I, eight with stage II, three with stage III, one with stage IV, and one with stage V). Arthroscopic interventions, including synovectomy, debridement, chondroplasty, microfracture, and loose body removal, were performed without considering the Smillie classification stage. Radiologic outcomes were evaluated by radiography (preoperatively and 3, 6, and 12 months postoperatively) and magnetic resonance imaging (preoperatively and 12 months postoperatively). Clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) lesser metatarsophalangeal (MTP)-interphalangeal score and the visual analog scale (VAS) score. The MTP joint range of motion was measured using a goniometer preoperatively and postoperatively.

Results: Radiologic studies showed no evidence of osteonecrosis progression in postoperative 12-month radiographs of any patients. Postoperative 12-month magnetic resonance images showed reduction of bone marrow edema, irregularity of subchondral bone, and cartilage defects in all patients. Significant improvements in AOFAS and VAS scores occurred at all postoperative time points compared with preoperative scores (P = .001). The MTP joint range of motion also showed improvement at last follow-up (P = .001).

Conclusions: Arthroscopic surgery for Freiberg disease showed excellent clinical outcomes, MTP joint range of motion, and short-term outcomes regardless of stage (Smillie classification) in radiologic evaluation.

Background: This study aimed to compare two-point discrimination in feet with ankle sprains and feet without ankle problems, and to determine whether there was a change in the two-point discrimination values in ankle sprains.

Methods: A total of 108 people were included in the study. These subjects were aged between 18 and 40 years and visited the Medical Faculty of Yozgat Bozok University for various reasons in July and September of 2022. These people were divided into two groups: subjects with an ankle sprain and subjects with no ankle problems. Two-point discrimination values measured in millimeters were recorded for both groups using a caliper (esthesiometer) used in six regions of 216 feet. The two-point discrimination threshold values of the feet were compared statistically according to feet with ankle sprains and feet without ankle problems, and in right and left feet.

Results: The study determined that the two-point discrimination threshold values measured at the first toe tip, heel, third plantar metatarsal head, medial malleolus, and lateral malleolus in subjects with an ankle sprain was higher than in subjects with no ankle problems. When comparing both feet of the subjects with an ankle sprain, the two-point discrimination threshold value in the heel of the foot with an ankle sprain was higher than in the heel of the foot without ankle problems.

Conclusions: The two-point discrimination threshold value was higher in subjects with an ankle sprain than in subjects with no ankle problems. The data suggest that the two-point discrimination threshold may be higher in people with an ankle sprain. Further studies are needed to better understand the two-point discrimination threshold in ankle sprains.

Background: This cross-sectional retrospective study aimed to present the influence of unilateral and bilateral flatfoot on coronal spinopelvic alignment in asymptomatic young healthy males.

Methods: This study was performed by examining the medical reports of individuals who applied to the National Health Board to work in positions requiring physical fitness between January 1, 2018, and January 1, 2019. Plain radiographs of the feet, pelvis, and spine were analyzed. The calcaneal pitch angle for flatfoot, pelvic obliquity, and the Cobb angle for spinal asymmetry were measured. After all of the analyses were completed, participants were divided into two groups-unilateral or bilateral flatfoot, depending on the calcaneal pitch angle measurements-and compared.

Results: There was no significant difference in age between groups (P = .609). The unilateral flatfoot group showed higher values in terms of body mass index, with a significant difference (P = .01). The curve patterns were identified as single thoracic, lumbar, and double. Post-hoc analyses suggest that young males without spinal asymmetry were more likely to have unilateral flatfoot (P < .008). There were significant differences between groups in pelvic obliquity and Cobb angle (P < .05). The effect size was found to be small to medium for pelvic obliquity and medium to large for Cobb angle.

Conclusions: Young males with bilaterally increased foot pronation demonstrate more increased pelvic obliquity and spinal curvature.

Background: Investigations of pain and physiologic responses response during Ponseti casting are in the preliminary stage. This short-term study aims to quantify pain responses and to note the variations, if any, during subsequent casting sessions.

Methods: In this prospective study, the pain parameters were evaluated in 34 clubfeet. Video recording of each casting session was performed 1 minute before casting, during casting, and after 1 minute of casting. The videos were scored objectively using Neonatal Infant Pain Score (NIPS). Heart rate (HR) and oxygen saturation were recorded by using a pulse oximeter.

Results: There was progressive increase in pain response until, at the last casting session, it was recorded as NIPS 4 (interquartile range, 1) (P = .02479). Before, during, and after casting, HR rose significantly in succeeding sessions. The mean HR during the first cast session was 175.5 ± 27.2/min, which increased to a mean of 197.3 ± 18.9/min (P = .000282). For the third parameter (oxygen saturation), no differences were observed between the first and last casting sessions.

Conclusions: There was moderate pain response during Ponseti casting sessions as demonstrated by the NIPS. It rose significantly toward the last cast. The clubfoot child showed an exaggerated heart rate in succeeding casting sessions. No variations were noticed for oxygen saturation.

Background: After an ankle sprain, the ligament and joint capsule are damaged, and as a result, proprioceptive sense is damaged, causing a feeling of giving away in the ankle and resulting in recurrent sprains. Given the relevant studies, it has been seen that people with chronic ankle instability (CAI) commonly have deficits in joint position sense and reinjury risks. Joint position sense plays an important role in ankle control, thereby reducing the risk of injury. Therefore, this study aims to compare the effects of balance and strength training on ankle proprioception in people with CAI.

Methods: This single-blind randomized controlled study included 29 volunteer participants (21 women and eight men) aged 18 to 30 years. Participants with a Cumberland ankle instability scale score less than or equal to 24 were randomly divided into two treatment groups: strength training (n = 14) and balance training (n = 15). Y balance test, joint position, and vibration sense were evaluated at the beginning and end of the treatment. "Hop to stabilization" exercises were applied to the balance group and resistive bands exercises to the strength group, which were performed for 6 weeks, 35 minutes per day, two times per week.

Results: There was no significant difference between the two groups in the anterior, posterolateral, and posteromedial directions of the Y balance test (P = .89, P = .50, and P = .34, respectively), but the strength training group showed significant improvement in ankle proprioception (140°) and vibration sense (fifth finger) (P < .001), and the post hoc Cohen's d effect size values were medium (.52) and small (.25), respectively.

Conclusions: The findings of this study show that strengthening and balance exercises have similar effects on dynamic balance, but strengthening exercises are more effective in improving joint position and vibration sense. Given the positive effects of both exercise programs, it is recommended to implement the two interventions separately or together for CAI rehabilitation.

Charcot's neuroarthropathy and osteomyelitis can have similar initial presentations. The ability to differentiate between the two pathologic conditions is essential, as each requires different treatment. We present a case of a 53-year-old woman with pain, swelling, and warmth in her left first metatarsophalangeal joint and first tarsometatarsal joint. Radiographs showed comminuted fractures at the base of the first metatarsal. Osteomyelitis was suspected by the primary team based on physical findings and a history of previous first metatarsophalangeal joint arthrodesis. A triphasic bone scan and an indium white blood cell scan were positive for osteomyelitis. The podiatric medical team was suspicious for possible Charcot's neuroarthropathy based on physical findings and uncontrolled blood glucose levels at the time of her previous arthrodesis. A sulfur colloid scan was performed and compared with an indium scan, which showed no evidence of osteomyelitis. This case demonstrates the usefulness of sulfur colloid imaging compared with an indium white blood cell scan to differentiate osteomyelitis from Charcot's neuroarthropathy. This case also highlights the importance of using clinical judgment to make the correct diagnosis.

Background: The ideal suture technique and type in tendon repair remain unclear. This biomechanical study aimed to assess the biomechanical characteristics of three techniques-modified Kessler (mKE), modified Krackow (mKR), and modified tension Bunnell (mtBU)-in sheep Achilles tendon tear repair using three suture types-polypropylene, polyester, and ultra-high-molecular-weight polyethylene (UHMWPE)-which are also compared.

Methods: Sixty-three Achilles tendons harvested from sheep were transversely hacked as a replacement for rupture in a standardized measure and repaired using mKE, mKR, and mtBU techniques with No. 2 polypropylene, polyester, and UHMWPE sutures. Biomechanical parameters, such as Young's modulus, ultimate strength, and strength to the 5-mm gap, were recorded for statistical analysis.

Results: The mtBU technique with UHMWPE use resulted in increased ultimate strength, strength to 5-mm gap, Young's modulus, and quantity of specimens with low clinical failure modes compared with the other techniques with other suture materials. Furthermore, mtBU has the lowest thickness at the repair side of the tendons. This approach showed tendon failure during maximal traction testing, whereas the mKE and mKR techniques had polyethylene and polyester suture failures.

Conclusions: The UHMWPE suture was significantly superior to the other sutures in each technique in terms of strength and durability. The mtBU technique using UHMWPE suture showed better biomechanical results, implying that this repair might be more appropriate to obtain early mobilization after tendon ruptures.

Background: The purpose of this study was to determine the association of preulcerative foot care and outcomes of diabetic foot ulcerations (DFUs).

Methods: This retrospective cohort study using the Mariner all-payers claims data set included participants with a new DFU from 2010 to 2019. Patients were stratified into two cohorts (foot care and control) based on whether they had received any outpatient foot care within 12 months before DFU. Adjusted comparison was performed by propensity matching for age, sex, and the Charlson Comorbidity Index (1:2 ratio). Kaplan-Meier estimates and logistic regression examined the association between foot care and outcomes of DFUs.

Results: Of the 307,131 patients in the study cohort, 4.7% (n = 14,477) received outpatient preulcerative foot care within the 12-month period before DFU. The rate of major amputation was 1.8% (foot care, 1.2%), and 9.0% of patients had hospitalizations for foot infection within 12 months after DFU (foot care, 7.8%). In the study cohort, patients who received pre-DFU foot care had greater major amputation-free survival (P < .001) on Kaplan-Meier estimate. In both the study and matched cohorts, multivariable analysis demonstrated that foot care was associated with lower odds of major amputation for both study (odds ratio [OR], 0.56; 95% confidence interval [CI], 0.48-0.66) and matched (OR, 0.61; 95% CI, 0.51-0.72) cohorts, and lower odds of hospitalizations for a foot infection in both study (OR, 0.91; 95% CI, 0.86-0.96) and matched (OR, 0.88, 95% CI, 0.82-0.94) cohorts.

Conclusions: Among patients with a new DFU, those who received outpatient preulcerative foot care within 12 months of diagnosis had lower risks of major amputation and hospitalizations for foot infection.
