The management of complex and severe lower-extremity injuries is challenging for the orthopedic surgeon. When the primary or secondary closure of the defect is not feasible, complex procedures with graft (split-thickness or full-thickness) or flap (pedicled or free) are required. These procedures are performed by specialized plastic surgeons and are at high risk for adverse effects, even high morbidity among both the donor and acceptor sites. Furthermore, split-thickness skin grafts (STSGs) often lead to unsatisfactory results in terms of mechanical stability, flexibility, and aesthetics due to the lack of underlying dermal tissue. Consequently, dermal substitutes, such as MatriDerm (MedSkin Solutions Dr Suwelack AG, Billerbeck, Germany), have been proposed and further developed as a treatment option addressing the management of full-thickness wound defects in conjunction with STSGs. We aimed to present a case of post-traumatic full-thickness wound defect of the left foot after traumatic amputation of the digits that was treated with MatriDerm combined with autologous STSG. In addition, we performed a systematic review of the literature to delineate the efficacy of the use of MatriDerm combined with STSGs in orthopedic cases exclusively.

Background: Socks are mainly used to give the foot more comfort while wearing shoes. Stitch density of the knitted fabric used in socks can significantly affect the sock properties because it is one of the most important fabric structural factors influencing the mechanical properties. Continuous plantar pressures can cause serious damage, particularly under the metatarsal heads, and it is deduced that using socks redistributes and reduces peak plantar pressures. If peak pressure under the metatarsal heads is predicted, then it will be possible to produce socks with the best mechanical properties to reduce the pressure in these critical areas.

Methods: Plain knitted socks with three different stitch lengths (high, medium, and low) were produced. Static plantar pressure measurements by the Gaitview system were accomplished on ten women and then compared with the barefoot situation. Also, the peak plantar pressure of three types of socks under the metatarsal heads are theoretically predicted using the Hertz contact theory.

Results: Experimental results indicate that all socks redistribute the plantar pressure from high to low plantar pressure regions compared with barefoot. In particular, socks with high stitch length have the best performance. By increasing the stitch length, we can significantly reduce the peak plantar pressure of the socks. Correspondingly, the Hertz contact theory resulted in a trend of mean peak pressure reductions in the forefoot region similar to the socks with different stitch densities.

Conclusions: The theoretical results show that by using the Hertz contact theory, static plantar pressure in the forefoot region can be well predicted at a mean error of approximately 9% compared with the other experimental findings.

Background: An abnormal hallux interphalangeal angle may be an important risk factor for the recurrence of ingrown toenails.

Methods: Sixty pediatric patients who underwent surgery for an ingrown toenail were evaluated retrospectively in terms of recurrence. The patients were divided into two groups. Group 1 included 30 patients (22 boys and eight girls) with hallux valgus interphalangeal deformity. Group 2 included 30 patients (20 boys and ten girls) without toe deformity.

Results: The mean ± SD patient age was 12.8 ± 1.42 years and 12.5 ± 1.45 years in groups 1 and 2, respectively. There was no significant difference between the patient and control groups in terms of age and sex (P > .05). The mean ± SD follow-up time was 30.2 ± 13.46 months in group 1 and 31.3 ± 12.86 months in group 2 (P = .286). We observed recurrence in six patients (20%) in group 1 and in two patients (6.7%) in group 2.

Conclusions: The recurrence of an ingrown toenail may be associated with an increased hallux interphalangeal angle in pediatric patients. Factors related to the hallux interphalangeal angle abnormality, which increases the risk of ingrown toenails, also increase the recurrence rate in these patients. Therefore, it is surmised that hallux valgus interphalangeal deformity should be evaluated before surgery, and patients and their families should be informed about the increased risk of recurrence.

Background: The aim of this study was to measure the quality of information about "flatfoot" and "pes planus" presented online on the social media site YouTube and to determine the trends of viewers to medical information on YouTube.

Methods: "Flatfoot and pes planus" was typed into the YouTube search module. From the search results, videos with 50,000 views or more, longer than 45 seconds, and containing information about flatfoot and pes planus disease were selected. DISCERN and JAMA scoring, daily average views, number of likes, and number of comments were collected from 53 videos that met the criteria. The profession of the sharer was evaluated in terms of the information quality of the sharing and the orientation of the audience.

Results: The mean number of views per day of the examined videos was 2,047. The mean video presentation time was 8 minutes 50 seconds. The mean JAMA score was 2 of 4 and the mean DISCERN score was 38.16 of 75. According to the DISCERN score according to the professions, the video quality was moderate for doctors (41.44 ± 12.99), moderate for physiotherapists (41.91 ± 9.04), poor for coaches (32.78 ± 7.87), poor for patients (34.50 ± 5.32), and weak for others (34.89 ± 14.00). According to the Spearman correlation between DISCERN score and mean daily viewing, significant relationships were found for the doctors (P = .0102) and others groups (P = .0033); however, no significant relationships were observed for the physiotherapists group (P = .1073), the flatfoot patients group (P = .5363), and the coaches group (P = .9111). There were significant relationships between like and comment counts in all groups (doctors, P = .0088; coaches, P = .0069; physiotherapists, P = .0007; others, P =.0018; and patients, P = .0066).

Conclusions: Looking at previous studies, it was observed that the quality of online health information was historically inadequate. Likewise, in our study on YouTube, we found that the quality of flatfoot and pes planus information was poor to moderate.

Background: There are various factors affecting the use of prostheses. This study was aimed to examine satisfaction, psychological state, quality of life, and the factors affecting these in individuals who use prostheses because of lower-extremity amputation.

Methods: Sixty-three patients were included in this study. Demographic data and features related amputation and prosthesis were recorded. Quality of life was evaluated with the Nottingham Health Profile (NHP), anxiety and depression levels were evaluated with the Hospital Anxiety Depression Scale (HADS), body image was evaluated by the Amputee Body Image Scale (ABIS), prosthesis satisfaction was evaluated with the Prosthesis Satisfaction Questionnaire (PSQ), and the relationship between them was examined.

Results: There was a positive correlation between all HADS scores, NHP-emotional reactions, NHP-sleep, NHP-social isolation, NHP-total, and ABIS (P < .05). A negative correlation was found between HADS-anxiety and PSQ results (r = -0.394, P = .003). A positive correlation was found between HADS-depression scores and NHP-pain, NHP-emotional reactions, NHP-social isolation, NHP-total, and ABIS (P < .05); and a negative correlation was found with PSQ questionnaire scores (r = -0.427, P = .001). There was a positive correlation between HADS-total scores and all parameters except NHP-energy level and ABIS (P < .05). A positive correlation was found between ABIS and all parameters except NHP-energy level (P < .05). A negative correlation was found between PSQ and NHP-social isolation, NHP-physical activity, and NHP-total scores (r = -0.312, P = 0.019; r = -0.312, P = .019; and r = -0.277, P = .039, respectively). The presence of residual extremity pain was found to be an effective factor on the psychological state (β = 0.429, P = .001). The presence of residual limb pain and phantom pain were found to be effective factors on the prosthesis satisfaction (β = -0.41, P = .001; and β = -0.406, P = .001, respectively). The presence of residual extremity pain and anxiety level were found independent risk factors on the NHP (β = -0.401, P = .006; and β = -0.445, P = .006, respectively).

Conclusions: Individuals using prostheses because of lower-extremity amputation should be examined in detail from various perspectives.

Background: First metatarsophalangeal joint arthrodesis with isolated dorsal plating without a lag screw and without a compressive mechanism incorporated into the plate is not well studied. Although surface area for bony fusion is increased, there is concern for lower fusion rates and progressive loss of sagittal plane positioning. We present fusion rates and progressive sagittal plane deviation with isolated dorsal plate fixation.

Methods: A retrospective review was performed of 41 patients (43 feet) who underwent first metatarsophalangeal joint arthrodesis with isolated dorsal plate fixation. Patients were excluded if another form of fixation was used, if there was a compressive feature to the dorsal plate, or if a lag screw was used. Preoperative, immediate postoperative, and final postoperative radiographs were reviewed to assess radiographic alignment and fusion about the first metatarsophalangeal joint. Specific attention was placed on hallux dorsiflexion in relation to the first metatarsal. Statistical significance was set at P ≤ .05 a priori.

Results: Patients were followed for an average of 55.7 weeks. Overall union rate was 97.62%. The average time to union was 42.55 days. Reoperation rate was 4.65%, with one patient requiring revisional arthrodesis with a lag screw construct. Hallux abduction and first-second intermetatarsal angle correction reached significance (P < .00001). Hallux dorsiflexion increased by 1.05° between initial postoperative and final postoperative radiographs (P = .542).

Conclusions: Although fusion rates and progressive loss of sagittal plane position have been concerns for first metatarsophalangeal joint arthrodesis with an isolated dorsal plate construct, these results suggest this to be a stable construct without loss of positioning over time.

Background: The effectiveness of different energy levels used in extracorporeal shockwave therapy (ESWT) has been investigated in previous studies, but controversy remains regarding which energy levels should be used in the treatment of plantar fasciitis. We compared the efficacy of different energy levels used in ESWT in the treatment of plantar fasciitis using plantar fascia thickness and pressure distribution.

Methods: Between July 2021 and September 2021, a total of 51 patients (71 feet) with plantar fasciitis were randomized into three treatment groups using the sealed envelope method. Group 1 (n = 25) received low energy density (0.09 mJ/mm2), group 2 (n = 25) received medium energy density (0.18 mJ/mm2), and group 3 (n = 21) received high energy density (0.38 mJ/mm2). Each group received three sessions of ESWT at a frequency of 2,000 shocks per minute at 1-week intervals. Patients were evaluated before and after treatment using a visual analog scale (VAS) for pain, the Foot Function Index (FFI), plantar fascia thickness measured by ultrasonography, and plantar pressure distribution.

Results: Posttreatment VAS and FFI scores were determined to be significantly lower than the values before treatment in the three groups (P < .001). There were no significant differences among groups in pretreatment and posttreatment values of VAS, FFI, plantar fascia thickness, and pressure distribution (P > .05). No significant differences were found among groups in percentage changes in all of the outcome parameters (P > .05).

Conclusions: There was no superiority among low, medium, or high levels of ESWT in terms of pain, foot functions, fascia thickness, and pressure distribution in the treatment of plantar fasciitis.

Os subtibiale is a rare accessory ossicle of the ankle, considered not of clinical significance. But its presence in trauma patients may cause misdiagnosis as malleolar fracture and over-treatment. Because the ossicle is attached to the deltoid ligament, ankle trauma that cause medial compartment injury may detach os subtibiale from medial malleolus. In these situations, MR imaging may help to diagnose the deltoid injury, demonstrate the features of the ossicle, and guide treatment.

Background Ankle fractures constitute 10% of all traumatic fractures in clinical practice. Concurrent tibiotalar dislocations form 21-36% of all ankle fractures. Although mechanism of injury is similar to non-dislocated ankle fractures, fracture-dislocations cause more extensive bone and soft tissue damage. Treatment is a challenge for orthopedic surgeons due to concomitant pathologies. It is associated with malreduction, chronic pain and most importantly, posttraumatic osteoarthritis. We aimed to investigate the relationship between ankle osteoarthritis radiographic stage and clinical outcomes. Methods 27 patients (17 female, 10 male) were included in the study. Records and data were retrospectively analyzed. Clinical status at the final follow-up was evaluated by a single orthopedic surgeon. Range of motion (ROM), American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score, visual analogue scale (VAS) were the clinical parameters that were assessed. Radiological assessment was made by standard anteroposterior [AP], lateral, and mortise views. Pre-operative osseo-ligamentous injury pattern, presence of posterior malleolar fracture, syndesmosis injury and post-operative ankle osteoarthritis were investigated. Results For 27 patients that were evaluated, at the final follow-up, mean AOFAS was 85 ± 8.12, and mean VAS during daily activities was 1.52 ± 0.70. Mean ankle dorsiflexion and plantar flexion were significantly lower on the affected sides (14.07 ± 7.97° and 36.30 ± 6.59°) than on the unaffected sides (28.15 ± 2.82° and 46.30 ± 2.97°), respectively (p < 0.001). No significant difference for inversion and eversion was observed. Twenty-four patients demonstrated radiographic signs of ankle osteoarthritis, and three remained without evidence of osteoarthritis. No significant difference was found among Takakura's stages in any of the variables. Conclusion The results illustrated that although post-traumatic osteoarthritis rate was high for ankle fracture-dislocation patients, surgical treatment achieved excellent functional results. Even if advanced stages of ankle arthritis according to Takakura's classification developed, patients had satisfactory clinical and functional results.

Background: This article aims to analyze levels of knowledge and behavior about diabetic foot care and prevention in persons with diabetes according to International Working Group (IWGDF) risk stratification system.

Methods: A descriptive study in 83 persons with diabetes at different level of risk for foot ulceration (IWGDF risk 0-3). A previously validated questionnaire, the PIN Questionnaire, was used to analyze their levels of understanding of foot complications. Participants were responded on a 5-point Likert scale.

Results: IWGDF-3 risk patients knew that good circulation and absence of polyneuropathy in their feet were related to healthy feet relative to the other groups (19.6 ± 2.7, p<.001 and 14.2 ± 0.7, p<.001 respectively). Additionally, they knew that a foot ulcer (DFU) on their feet will not be painful relative to other groups (6.6 ± 2.8, p<.001). High-risk patients knew which physical causes could affect the development of a DFU (18 ± 1.4, p<.001) and that foot self-care and medical control could prevent DFU appearance (23.4 ± 2.15, p<.001 and 13.9 ± 0.9, p<.001 respectively).

Conclusion: IWGDF-3 patients knew the natural progression of diabetes foot complications and how to prevent them. Clinicians should focus their efforts and educate diabetes at lower risk of foot ulcer.
