Return to sport activities after subtalar arthroereisis for correction of pediatric flexible flatfoot.

The aim of this study was to establish whether children treated with subtalar arthroereisis for flexible flatfoot were able to return to sport activities. We reviewed 49 patients with a mean age at the time of surgery of 10.7 years. The type of sport activities, the number of sessions per week, the time dedicated to each session, and the level achieved were assessed preoperatively and at the last follow-up. Overall, 45 patients returned to sports after surgery. Surgery did not alter the duration, frequency, and type of sporting activities, but the participation in physical activities as well as the emotional status and footwear issues improved.

Recreational Sports Activities After Calcaneal Fractures and Subsequent Subtalar Joint Arthrodesis.

Subtalar joint arthrodesis is a common treatment for the management of hindfoot pathologic entities. Despite pain reduction, hindfoot stiffness is a common concern of active patients, who wish to continue or start exercising for fitness. The purpose of the present retrospective observational clinical study was to assess the rate and type of recreational sports activities in patients before and after subtalar joint arthrodesis and to correlate the clinical outcome and the level of sports activities. In 33 patients (22 males, 11 females) treated with subtalar joint arthrodesis, the pre- and postoperative participation in sports and recreational activities was evaluated. The American Orthopaedic Foot and Ankle Society hindfoot scale score, 36-item Short Form Health Survey, and a visual analog scale for pain were used as clinical outcome measures. The weekly session number, session time, and interval to activity recovery after surgery were registered. Patients with a subtalar joint arthrodesis returned to a satisfactory level of activity postoperatively. The sports participation almost reached levels similar to those preoperatively but with a shift from high- to low-impact activities.

Treatment of bone marrow edema of the talus with pulsed electromagnetic fields: outcomes in six patients.

BACKGROUND: Bone marrow edema (BME) of the talus is a rare, mostly self-limiting cause of foot and ankle pain. We sought to investigate in patients with idiopathic BME of the talus the effectiveness of pulsed electromagnetic fields and to determine the effect of this therapy on magnetic resonance imaging findings. METHODS: Six patients with BME of the talus confirmed by magnetic resonance imaging were enrolled. Pain was quantified with a visual analog scale from 0 (no pain) to 10 (the worst pain imaginable). The clinical outcome was assessed using the American Orthopaedic Foot and Ankle Society scoring system. Treatment consisted of pulsed electromagnetic field stimulation 8 h/d for 30 days. The device used generated pulses 1.3 milliseconds in duration, with a frequency of 75 Hz and a mean ± SD induced electric field of 3.5 ± 0.5 mV. RESULTS: The mean American Orthopaedic Foot and Ankle Society score improved from 59.4 (range, 40-66) before treatment to 94 (range, 80-100) at the last follow-up. The visual analog scale score decreased significantly from 5.6 (range, 4-7) before treatment to 1 (range, 0-2) at the last follow-up. Magnetic resonance imaging showed that BME improved after 1 month of treatment and resolved completely within 3 months in 5 patients, with normal signal intensity and no signs of progression to avascular necrosis. CONCLUSIONS: A significant reduction in BME area was associated with a significant decrease in pain within 3 months of beginning treatment.

Acute rupture of the tibialis posterior tendon without fracture: a case report.

The acute rupture of the tibialis posterior (TP) tendon, compared to an acute rupture of the Achilles tendon, is a quite uncommon disease to be diagnosed in the emergency department setting. In most cases symptoms related to a TP dysfunction, like weakness, pain along the course of the tendon, swelling in the region of the medial malleolus, and the partial or complete loss of the medial arch with a flatfoot deformity precede the complete rupture of the tendon. In this case report, we describe an acute rupture of the TP tendon following a pronation-external rotation injury of the ankle with no association of a medial malleolus fracture and with no history of a prior flatfoot deformity or symptoms.

Reliability, validity and responsiveness of the Italian version of the Foot Function Index in patients with foot and ankle diseases.

PURPOSE: The purpose of this study was to translate the Foot Function Index (FFI) into Italian, to perform a cross-cultural adaptation and to evaluate the psychometric properties of the Italian version of FFI. METHODS: The Italian FFI was developed according to the recommended forward/backward translation protocol and evaluated in patients with foot and ankle diseases. Feasibility, reliability [intraclass correlation coefficient (ICC)], internal consistency [Cronbach's alpha (CA)], construct validity (correlation with the SF-36 and a visual analogue scale (VAS) assessing for pain), responsiveness to surgery were assessed. The standardized effect size and standardized response mean were also evaluated. RESULTS: A total of 89 patients were recruited (mean age 51.8 ± 13.9 years, range 21-83). The Italian version of the FFI consisted in 18 items separated into a pain and disability subscales. CA value was 0.95 for both the subscales. The reproducibility was good with an ICC of 0.94 and 0.91 for pain and disability subscales, respectively. A strong correlation was found between the FFI and the scales of the SF-36 and the VAS with related content, particularly in the areas of physical function and pain was observed indicating good construct validity. After surgery, the mean FFI improved from 55.9 ± 24.8 to 32.4 ± 26.3 for the pain subscale and from 48.8 ± 28.8 to 24.9 ± 23.7 for the disability subscale (P < 0.01). CONCLUSIONS: The Italian version of the FFI showed satisfactory psychometric properties in Italian patients with foot and ankle diseases. Further testing in different and larger samples is required in order to ensure the validity and reliability of this score.

Distal oblique first metatarsal osteotomy in grade 3 hallux rigidus: a long-term followup.

BACKGROUND: While some studies have demonstrated that metatarsus primus elevatus in hallux rigidus is an uncommon secondary change rather than a causative factor, we believe it is, in fact, more common. We advocate surgical treatment if the first ray is elevated beyond normal range, thereby acting as a decompression realignment osteotomy. MATERIALS AND METHODS: We analyzed patients operated between June 1994 and December 1996. Oblique distal osteotomy of the first metatarsal was performed in 20 patients. A retrospective review of clinical and radiological outcomes was performed including an AOFAS score and patient satisfaction scale. The postoperative ROM was evaluated with lateral radiographs in maximum plantar/dorsiflexion. The average followup was 11.1 (range, 8.7 to 13.6) years. RESULTS: One case of metatarsalgia was the only postoperative complication. The average AOFAS score increased from 44 (range, 14 to 68) to 82 (range, 80 to 100). Good to excellent results were achieved in 19 patients. The mean passive dorsiflexion of the first MTP joint improved from 8 degrees (range, 5 degrees to 10 degrees) to 44 degrees (range, 15 degrees to 55 degrees). No patient underwent subsequent surgery. CONCLUSION: The oblique osteotomy is a safe and reliable procedure for treatment of painful hallux rigidus. In our experience, it yields good and excellent results with high patient satisfaction and low complication rates.
