The comparison of the effect of corticosteroids and platelet-rich plasma (PRP) for the treatment of plantar fasciitis.

INTRODUCTION: In this study, the results of local injection of platelet-rich plasma (PRP) and corticosteroids in the treatment of plantar fasciitis were compared. PATIENTS AND METHODS: Sixty patients who were diagnosed as plantar fasciitis and treated conservatively for at least 3 months and had no response to conservative treatment modalities were involved in this study. The first 30 consecutive patients were treated by local injection of 2 mL of 40 mg Methylprednisolone with 2 mL of 2% prilocaine (metilprednizalone) and the second 30 patients were treated by injecting 3 mL PRP after 2 mL of 2% prilocaine injection. Patients were evaluated according to the modified criteria of the Roles and Maudsley scores and visual analog scale before injection and 3 weeks and 6 months following injection. RESULTS: The mean VAS heel pain scores measured 6 months after treatment were 3.4 in steroid group and 3.93 in PRP group, and the scores in both groups were significantly lower when compared with pretreatment levels (6.2 in steroid group and 7.33 in PRP group). There was no significant difference between steroid and PRP groups in visual analog scale scores and modified criteria of the Roles and Maudsley scores measured at 3 weeks and 6 months (P > 0.05). CONCLUSION: Our results revealed that both methods were effective and successful in treating plantar fasciitis. When the potential complication of corticosteroid treatment was taken into consideration, PRP injection seems to be safer and at least having same effectivity in the treatment of plantar fasciitis.

Single or double distal locking in intramedullary nailing of tibial shaft fractures: a prospective randomized study.

BACKGROUND: The number of distal locking screws may have an effect on union, complication rates and operation time. The purpose of this study was to determine the effect of one or two distal locking screws in unreamed intramedullary nailing of closed or grade 1 open, simple or wedge tibial shaft fractures on the incidence of malunion, delayed union, non-union, and screw failure. METHODS: Fifty-seven patients (39 male, 18 female; mean age 38.5+/-10.7 years) were randomized to two groups as either one or two distal locking screws and were evaluated prospectively for the incidences of malunion, delayed union, non-union, and screw failure. Twenty-nine patients were included in the two distal screws group and 28 patients in the single distal screw group. Groups were then subdivided to end fractures (proximal+distal end fractures) or mid-shaft fractures and reevaluated for the incidences of complications. Mann-Whitney U, chi-square and T tests were used for statistical analysis. RESULTS: Mean follow-up was 2.4 years (range, 1.5-4.7 years). There was no case of malunion in either group. The incidences of delayed union, non-union or screw failure were not different (p>0.05). However, complication rate for end fractures in the two screw group was higher than that in the one screw group (p:0.04). CONCLUSION: For non-complex, closed or grade 1 open tibial shaft fractures, locking of an intramedullary nail with a single distal screw is safe, and may help to decrease operation time and radiation exposure.

Role of pathophysiology of patellofemoral instability in the treatment of spontaneous medial patellofemoral subluxation: a case report.

INTRODUCTION: Medial patellar subluxation is usually seen after lateral retinacular release. Spontaneous medial subluxation of the patella is a very rare condition. There are few reports in the literature on the pathophysiology of iatrogenic medial patellar subluxation. To our knowledge, there are no reports of the pathophysiology of non-iatrogenic medial patellar subluxation in the English literature. In this study we present a case of spontaneous medial patellar instability that is more prominent in extension during weight bearing. We also try to define the treatment protocol based on pathophsiology. CASE PRESENTATION: We report the case of a 21-year-old Turkish man with spontaneous medial patellar instability. He had suffered right knee pain, clicking and popping sensation in the affected knee for three months prior to presentation. Clinical examination demonstrated medial patellar subluxation that is more prominent in extension during the weight bearing phase of gait and while standing. Increased medial tilt was observed when the patella was stressed medially. Conventional anterior to posterior, lateral and Merchant radiographs did not reveal any abnormalities. After three months of physical therapy, our patient was still suffering from right knee pain which disturbed his gait pattern. Throughout the surgery, medial patellar translation was tested following the imbrication of lateral structures. He still had a medial patellar translation that was more than 50% of his patellar width. Patellotibial ligament augmentation using an iliotibial band flap was added. When examined after surgery, the alignment of the patella was effectively corrected. CONCLUSIONS: Chronic imbalance between the strengths of vastus lateralis and vastus medialis results in secondary changes in passive ligamentous structures and causes additional instability. Physical therapy modalities that aim to strengthen the vastus lateralis might be sufficient for the treatment of spontaneous medial instability. There would be no need for any surgical intervention if spontaneous medial instability was recognized before the additional instability occured. If necessary, lateral imbrication followed by lateral patellotibial ligament augmentation can be performed, and these would effectively correct spontaneous medial patellofemoral instability.
