Validation of the Chinese Manchester foot pain and disability index (C-MFPDI) among patients with inflammatory arthritis

Combined with the first dorsal (plantar) metatarsal artery pedicle free bilobed flap with a cell scaffold for the repair of a mid-distal adjacent finger defect: a retrospective study

PURPOSE

Assessing the clinical effectiveness of combining with the first dorsal (plantar) metatarsal artery pedicle free bilobed flap with a cell scaffold to repair mid-distal defects in adjacent fingers.

METHODS

From September 2012 to April 2022, 21 patients with 42 mid-distal defects of adjacent fingers underwent treatment using combined with the first dorsal (plantar) metatarsal artery pedicle free bilobed flap with a cell scaffold. The flaps size ranged from 2.1 cm * 1.6 to 4.9 cm * 3.2 cm. Follow-up evaluations included assessing function, sensation, and appearance, etc. of the injured fingers and donor areas.

RESULTS

All 42 flaps survived in 21 patients without any vascular crises, and the wounds healed in phase I. The mean follow-up time was 12.2 months (range 7-22 months). During follow-up, in injured fingers, according to the Michigan Hand Outcomes Questionnaire (MHOQ), the functional recovery and appearance were satisfactory; in Dargan Function Evaluation (DFE), the results were both "excellent" in fourteen patients, "excellent" and "good" in five patients, both "good" in one patient, "good" and "general" in one. In static two-point discrimination (2PD), the variation ranges from 4 to 9 mm in injured fingers and 6-10 mm in donor toes. Cold Intolerance Severity Score (CISS) is mild in all patients. The visual analogue score (VAS) showed no pain in the injured fingers and donor toes. No deformities or other complications were noted at the donor toes. According to Chinese Manchester Foot Pain and Disability Index (C-MFPDI), there was no morbidity on foot function in all donor areas.

CONCLUSION

The surgical procedure of combined with the first dorsal (plantar) metatarsal artery pedicle free bilobed flap with a cell scaffold for the repair of mid-distal adjacent fingers defect is highly satisfactory. This approach helps the injured fingers to achieve good function, sensibility and appearance, while also achieving satisfactory results in the donor toes.

A New Minimally Invasive Procedure for Treating Plantar Heel Pain: Stromal Vascular Fraction Gel Grafting

METHODS

Fourteen patients who experienced plantar heel pain and underwent plantar heel SVF-gel grafting between January 2019 and June 2020 were included in this retrospective study. Foot pain and disability were measured at the screening visit and at the 3-, 6-, and 12-month follow-up visits. The volume of the heel fat pad was measured by magnetic resonance imaging.

RESULTS

Four of the patients had bilateral plantar heel pain, and 10 patients had unilateral plantar heel pain. All patients showed significant improvements in pain and foot function at 3 months after SVF-gel grafting compared with the baseline, with the greatest improvement at 6 months and the effect lasting 1 year or more. In addition, the thickness of the heel fat pad was significantly greater than at baseline at 3 months, and the effect lasted for 1 year or more.

CONCLUSION

Stromal vascular fraction gel grafting is a safe, minimally invasive, and effective approach to treat plantar heel pain.

How to measure success in lower extremity reconstruction, which outcome measurements do we use a systematic review and metanalysis

Different factors have to be considered and weighted in the treatment algorithm of lower extremity reconstruction. A combination of both clinicians' and patients' perspectives is necessary to provide a conclusive picture. Currently, there aren't any standardized and validated measurement data sets for lower extremity reconstructions. This makes it necessary to identify the relevant domains. We, therefore, performed a systematic review and metanalysis of outcome measurements and evaluated their ability to measure outcomes after lower extremity reconstruction. A systematic review and metanalysis according to the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' protocol were performed for studies reporting at least one structured outcome measurement of lower extremity reconstruction. Both Patient (PROMs)- and Clinician reported outcome measurements (CROMs)were analyzed. Of the 2827 identified articles, 102 were included in the final analysis. In total 86 outcome measurements were identified, 34 CROMs, 44 PROMs and 8 (9.3%) outcome measurements that have elements of both. Twenty-four measure functional outcome, 3 pain, 10 sensations and proprioception, 9 quality of life, 8 satisfaction with the result, 5 measure the aesthetic outcome, 6 contours and flap stability and 21 contain multidomain elements. A multitude of different outcome measurements is currently used in lower extremity reconstruction So far, no consensus has been reached on what to measure and how. Validation and standardization of both PROMs and CROMs in plastic surgery is needed to improve the outcome of our patients, better meet their needs and expectations and eventually optimize extremity reconstruction by enabling a direct comparison of studies' results.

Translation, Cultural Adaptation, and Psychometric Evaluation of the Manchester Foot Pain and Disability Index in Persian-Speaking Iranians With Foot Disorders

Foot pain has a significantly detrimental effect on mobility, function, and health status. Researchers have developed a number of measurement tools to assess foot health and its impact on quality of life. This study was conducted to translate the original English Manchester Foot Pain and Disability Index (MFPDI) into Persian and to examine the psychometric properties of the Persian version. A total of 206 patients with a range of foot disorders filled out the Persian version of the MFPDI and the Short-Form 36 Health Survey. The Persian version of the MFPDI was re-completed by the participants at an interval of 5 to 7 days. The analyses performed included internal consistency, test-retest reliability, construct validity, and floor and ceiling effect analysis. The Persian MFPDI had a good internal consistency (Cronbach's α ≥ 0.70) and test-retest reliability (intraclass correlation coefficient = 0.84). The construct validity of the Persian MFPDI was demonstrated to be acceptable as a result of its significantly strong negative correlations with the Short-Form 36 Health Survey. The results of this study showed that the Persian version of the MFPDI is a valid and reliable measure to assess foot-related disability.

Reconstruction of a Distal Foot Skin Defect Using an Intermediate Dorsal Neurocutaneous Flap

OBJECTIVE

To present the use of an intermediate dorsal neurocutaneous flap for the reconstruction of defects on the distal foot.

METHODS

From September 2016 to October 2018, five patients (mean age at operation 33.8 years; range, 7-70 years; female/male = 2/3) with skin defects on one of their feet caused by road-traffic accidents, electrical injury, and syndactyly correction were retrospectively reviewed. The size of the defects ranged from 2.0 cm × 1.0 cm to 5.0 cm × 3.5 cm. All patients had undergone a reconstruction surgery using intermediate dorsal neurocutaneous flap. One patient underwent a syndactyly correction, and four patients first experienced aggressive debridement. The sizes of the flaps were between 5.0 cm × 2.0 cm and 6.0 cm × 4.0 cm. The function, appearance, and pain of the injured foot were assessed using the Chinese Manchester Foot Pain and Disability Index and visual analogue scale.

RESULTS

These five patients were systematically followed up for a mean of 15.8 months (range, 12-20 months). The donor sites were closed primarily in two cases, and skin grafts were performed in three cases. All the flaps survived with a success rate of 100%; the wounds healed well, and the color matches were excellent. Partial superficial flap necrosis occurred in one of five flaps, which was treated by dressing change using a hypertonic saline gauze. No significant problems were found at the donor site in any patient immediately afterwards or at follow-up. There were no problems in any patients associated with wearing shoes. Based on the Chinese Manchester Foot Pain and Disability Index, four patients were strongly satisfied and one was satisfied with the recovery of physical function; all the patients were strongly satisfied with the appearance of the injured foot; all five patients had an excellent score of pain intensity subscale. Except for one patient who reported mild pain, all the other patients reported no pain based on the visual analogue scale. Two typical cases are presented in this paper.

CONCLUSIONS

The intermediate dorsal neurocutaneous flap is an alternative and effective technique that can reliably cover minor- to medium-sized defects on the distal foot, toes, and web spaces. This surgical method leads to satisfactory functional recovery with minimal donor site morbidity, and no major vessels need to be sacrificed. This procedure offers an advisable option for orthopaedic surgeons to treat defects on the distal foot.

Systematic review of the psychometric properties of patient-reported outcome measures for rheumatoid arthritis in the foot and ankle

OBJECTIVE

To identify self-reported outcome measures specific to the foot and ankle in patients with rheumatoid arthritis and to investigate the methodological quality and psychometric properties of these measures.

METHOD

A systematic review focusing on patients with rheumatoid arthritis.

SETTING

The search was conducted in the PubMed, SCOPUS, CINAHL, PEDro and Google Scholar databases, based on the following inclusion criteria: population (with rheumatoid arthritis) > 18 years; psychometric or clinimetric validation studies of patient-reported outcomes specific to the foot and ankle, in different languages, with no time limit. Two of the present authors independently assessed the quality of the studies located and extracted the relevant data. Terwee's criteria and the COSMIN checklist were employed to ensure adequate methodological quality.

RESULTS

Of the initial 431 studies considered, 14 met the inclusion criteria, representing 7,793 patients (56.8 years). These instruments were grouped into three dimensions (pain, perceived health status and quality of life and disability). The time to complete any of the PROMs varies around 15 minutes. PROMs criterias with the worst scores by COSMIN, 92.85% and 85.71% were criterion validity, measurement error, internal consistency and responsiveness. 28.57% of PROMs were compared with the measurement properties.

CONCLUSION

the Self-Reported Foot and Ankle Score achieved the highest number of positive criteria (according to Terwee and COSMIN), and is currently the most appropriate for patients with Rheumatoid arthritis.
