The purpose of the present study is to draw the necessary conclusions from the use of a particular surgical treatment to release the digital nerve, accompanied by neurolysis in adults who exercise. On the whole, twenty five patients with twenty-five suffering extremities were treated. Five of them simultaneously had a Hallux Valgus type deformity and that supports the belief of the mechanical induce of this condition. Both ultrasonography and Magnetic Resonance Imaging (MRI) were used for the clinical evaluation of this condition. The pain was estimated via the Visual Analogue Scale (VAS). The patients were re-examined after three (1st postoperative), twelve (2nd postoperative) and twenty-four (3rd postoperative) months. A significant improvement (p 0.0001) was noticed from the correlation between the pain before the surgery and the pain after the surgery via the Visual Analogue Scale (VAS). Most patients (15/25) did not display any discomfort or sensory disorder after surgery. The correct clinical evaluation as well as the correct and effective surgical intervention with the simultaneous repair of all the mechanical deformities of the foot provided better post-surgery progress in patients and increased the percentage of their rehabilitation of their previous activities.展开更多

The data showed that the metatarsalgia developed or was ag-gravated in 26 feet (23%), and was eliminated or alleviated in 23 feet (21%) afterKeller’s operation. When more than one-third of the proximal phalanx of the big toe wasresected, the incidence of the metatarsalgia obviously increased following surgery. Theautho rpreferred a "Z" lengthening of the extensor hallucis longus tendon instead ofresecting excessive proximal phalanx. The total incidence of the metatarsalgia was 36%(40 feet) preoperatively and 38% (43 feet) postoperatively. This result indicated thatthere was no obvious difference in the incidence of the preoperative and postoperativemetatarsalgia. No more than one-third of the proximal phalanx of the big toe should beremoved. This seems to reduce the incidence of the metatarsalgia after Keller’s operation.After operation, the three princepal symptoms of hallux valgus deformity, painful bunionand difficulty in shoe-wearing were improved for more than 95% in the 112 feet.Eighty one% of the patients were satisfied with the result of the operation. We considerthat this method is one of the effective operation for correcting the hallux valgusdeformity and it is also important to select suitable patients.展开更多

We report an exceptional localization of osteoid osteoma in the second metatarsal in a 30-year-old patient, expressed for 3 years by metatarsalgia, with no clinical and radiological architecture defect of the foot. After discovering the nidus, the patient underwent surgical excision with an excellent outcome.展开更多
