ABSTRACT

We used coronal computed tomography to determine the normal sesamoid position in 20 healthy volunteers. The sample involved 40 feet (20 left [50%] and 20 right [50%]) in 20 volunteers, including 11 females (55%) and 9 males (45%). The relationship between the first metatarsal head and the sesamoid complex was categorized as Yildirim grade 0 in every case (100%). The mean width of the foot was 77.7 ± 5.8 mm, and the ratio of the foot width to the distance from the second metatarsal head to the tibial sesamoid was 39.6% ± 2.02%. Based on our findings, we consider Yildirim grade 0 to be the normal sesamoid alignment.

ABSTRACT

Some investigators have emphasized restoring the relationship between the sesamoid complex and the first metatarsal head to reduce the risk of hallux valgus recurring after surgical reconstruction. In a prospective study, we analyzed whether the first metatarsophalangeal joint could be realigned after scarf-Akin bunionectomy without lateral soft tissue release. A total of 25 feet, in 22 patients, were prospectively enrolled and analyzed using anteroposterior radiographs and coronal computed tomography scans obtained before and 3 months after surgery. The Yildirim sesamoid position decreased from a preoperative of 2 (range 1 to 3) to a postoperative position of 0 (range 0 to 1; p < .001), the mean first intermetatarsal angle decreased from 12.6° ± 2.4° to 5.8° ± 2.1° (p < .001), and the mean distance between the second metatarsal and the tibial sesamoid changed from 25.7 ± 4.6 to 25.9 ± 4.6 (p = .59). Our findings suggest that dislocation of the sesamoid complex is actually caused by displacement of the first metatarsal. In conclusion, the scarf-Akin bunionectomy adequately restores the alignment of the first metatarsophalangeal joint, including restoration of the sesamoid apparatus, without direct plantar-lateral soft tissue release.

ABSTRACT

BACKGROUND: We evaluated a series of patients who underwent neurectomy or neurolysis for the surgical treatment of Morton's neuroma. MATERIALS AND METHODS: A group of 50 patients (69 feet) who underwent surgery for a symptomatic Morton's neuroma were retrospectively reviewed. Surgery was performed through a dorsal approach in all cases. When the nerve showed macroscopic thickening or the typical pseudoneuroma, it was resected; when the nerve had no macroscopic changes, the intermetatarsal ligament and any other potentially compressive structure were released. In 17 cases, adjacent claw toes were treated. RESULTS: Nerve thickening (pseudoneuroma) were resected in 46 cases; in the other 23 cases, the nerve was preserved. Total relief from digital nerve related symptoms was obtained in all cases but one in each group. These patients were reoperated on 6 months later by performing a neurectomy in the case where the nerve had been preserved, and a more proximal resection in the case in which the nerve had been resected. Both patients finally achieved complete pain relief. CONCLUSION: When treating Morton's neuromas surgically, neurolysis can be a valid option when a pseudoneuroma has not developed.

ABSTRACT

A series of 113 osteochondromas were treated in our institution with a long-term follow-up. A retrospective study of the cases of solitary osteochondroma diagnosed and treated in our center from 1970 to 2002 was done. A diagnosis for clinical findings in 73% of the patients was made. The most frequent location was the distal femur. Six patients had a recurrence and in two patients the lesions became malignant and chondrosarcoma developed. Relapse of the exostosis is rare, occurring in an estimated 2% of the resections. The growth of an osteochondroma and/or the presence of pain in older patients suggest possible malignancy.
