RESUMEN

Plantar fasciitis is a common cause of heel pain, which often results in a significant limitation of daily activity. The objective of this review was to compare platelet-rich plasma injection (PRP) and corticosteroids injection in the treatment of chronic plantar fasciitis. MEDLINE, PubMed, Web of Science, EMBASE, and the Cochrane library of clinical trials were searched in March 2019. Inclusion criteria were prospective comparative studies reporting functional scores or pain score with a minimum follow-up of 1 month. We excluded studies with patients younger than 18 years and patients with a history of surgical intervention, infection, or rheumatological disease. First author, publication year, sample size, type of intervention, outcome measures, and follow-up period were recorded. The American Orthopaedic Foot & Ankle Society score was significantly better in the PRP group at 6 months' follow-up, with a lower visual analogue scale at 6- and 12-month intervals. The Foot and Ankle Disability Index and Roles-Maudsley score were similar in the 2 treatments at 3 and 6 months. PRP injection in the treatment of chronic plantar fasciitis is considered safe, with a favorable functional outcome and pain control at intermediate and long-term follow-up in comparison to corticosteroid injection.

RESUMEN

PURPOSE: The indications of deltoid ligament repair in ankle injuries with widened medial clear space in the absence of medial malleolus fracture remain controversial. Many authors reported no difference in long-term functional outcomes, while others stated that persistent medial clear space widening and malreduction are higher when deltoid ligaments went without repair. This meta-analysis aims to report the current published evidence about the outcomes of deltoid ligament repair in ankle fractures. METHODS: Several databases were searched through May 2018 for comparative studies. The primary outcome was the medial clear space correction, while secondary outcomes included maintenance of medial clear space reduction, pain scores, functional outcome, and total complications if any. Three comparative studies met the inclusion criteria for the meta-analysis. The analysis included a total of 192 patients, 81 in the deltoid ligament repair group and 111 in the non-repair group. RESULTS: The medial clear space correction and maintenance of the said correction on final follow-up radiographs were superior in the deltoid ligament repair group. Although the pain scores were better in the repair group at the final follow-up, this did not result in a better functional outcome, with similar total complication rates. CONCLUSION: In conclusion, those who had their deltoid ligament repaired had superior early and late radiological correction of the medial clear space, an indicator of the quality of ankle reduction with better pain scores. However, no differences in the functional outcome and complications rate were reported.

RESUMEN

CASES: We present three cases of checkrein deformity associated with intra-articular talar fracture. Two of the cases were secondary to entrapment of the flexor hallucis longus (FHL) tendon between fracture fragments, and one was related to the increased pathway of the FHL tendon around the dislocated talar body. All cases were diagnosed and treated on the day of injury. CONCLUSION: Physicians should suspect the entrapment of the FHL tendon in cases of flexion deformity of the hallux associated with talar fracture. Proper examination of the forefoot when a patient presents with a hindfoot injury will help to avoid missing such deformities.
