So-called trigger ankle due to an aberrant flexor hallucis longus muscle in a tennis player. A case report.

The aim of this study is to find basic quantitative geometric data that may contribute to the understanding of the etiology of hallux valgus. Embalmed specimens with existing hallux valgus (N = 39) were dissected; 28 variables were measured with a Vernier caliper gauge and toe goniometer. Correlations between pairs of independent variables were calculated. Linear dependency of the hallux angle, varus angle, and the width of the forefoot on a number of independent variables was analyzed by multiple linear regression. A least squares method and a stepwise procedure were used. The distance from the tendon of the flexor hallucis longus muscle to the head of the first metatarsal bone explains more than other variables the variation in hallux angle and width of the forefoot. A widened forefoot is significantly correlated with both hallux and varus angles. The interrelation of the predictor parameters illustrates the complicated hallux valgus phenomenon.

Abstract Background Alkaptonuria is a rare genetic metabolic disorder due to deficiency of homogentisate 1,2-dioxygenase (HGD), an enzyme catalyzing the conversion of homogentisate to 4-maleylacetoacetate in the pathway for the catabolism of phenylalanine and tyrosine. HGD deficiency results in accumulation of homogentisic acid and its pigmented polymer. Ochronosis is a bluish-black discoloration due to the deposition of the polymer in collagenous tissues. Extensive ochronotic involvement of the Achilles tendon in alkaptonuria and its surgical treatment is rarely reported. Case report A 43-year-old man presented to our clinic in March 2019 with sudden onset of left Achilles tendon pain with no history of prior trauma. Surgical exploration revealed a complete disruption of the tendon at its attachment to the calcaneus. Black pigmentation was extensive and reached the calcaneal tuberosity, extending about 7 cm from the insertion. Discussion Achilles reconstruction was performed using flexor hallucis longus tendon transfer. The patient experienced uncomplicated healing with satisfactory functional results. Conclusion Orthopedic surgeons should be aware of the progressive nature of alkaptonuria. Extensive degenerative changes of the ruptured tendon should be suspected so that physicians can plan tendon repair and facilitate prompt surgical intervention.

AbstractMyxofibrosarcoma or myxoid malignant fibrous histiocytoma is one of the most common sarcomas of the limb. It is usually treated multimodally. Most frequent sites of metastasis are the bone, lung and lymph nodes. The present paper is a case report of a 65-year-old male with myxofibrosarcoma of the fibularis longus muscle, for which he first underwent surgery - tumor resection with appropriate margins. The tumor was staged pT2b cN0 cM0. Postoperative PET-CT revealed metabolically inactive pulmonary nodules. Two months after surgery, he underwent adjuvant radiotherapy, a total dose of 60 Gy and 6 courses of chemotherapy (doxorubicin and ifosfamide). Pulmonary nodules have been stationary on all subsequent imagistic studies. He is free of recurrence on long-term follow-up.

Tomography Scan

Coalition of the hallux sesamoids is an extremely rare condition. To our knowledge, only 1 case report has been published. We report a case of severe hallux valgus deformities with coalitions of the hallux sesamoids. The coalitions themselves were asymptomatic; however, this severe hallux valgus deformity needed to be surgically treated. The hallux sesamoids in both feet appeared to be fused and heart shaped on anteroposterior radiographs and dumbbell shaped on axial radiographs. It is known that postoperative incomplete reduction of the medial sesamoids can be a risk factor for the recurrence of hallux valgus. The computed tomography scan demonstrated a groove in the bottom of the center of the heart-shaped sesamoid. The flexor hallucis longus tendon was located in the groove. Therefore, a modified Lapidus procedure was performed considering the medial half of the heart-shaped sesamoid as the medial sesamoid. Although delayed union occurred, successful correction of the deformity was achieved. Levels of Evidence: Level IV
