Zero-profile implant versus integrated cage-plate implant in treatment of single level cervical disc disease.

The aim of this retrospective study is to evaluate and compare the clinical and radiological results of the use of Zero-P implant and the integrated cage-plate implant in surgical treatment of single level cervical disc disease. It includes 54 consecutive patients who underwent single level anterior cervical discectomy and fusion. The patients were divided into 2 groups. Group (A) including 28 patients operated with zero- profile implant and group (B) including 26 patients operated with integrated cage-plate implant. Mean operative time, blood loss, incidence of dysphagia and any other complications related to the procedure were recorded and compared. Patients were assessed radiologically by measuring cervical lordosis using the Cobb angle and the segmental angle. Patients were assessed clinically by the Japanese orthopedic association score and the neck disability index. These values were also compared. The mean age of the patients in group (A) was 49.5±11 years, and in group (B) it was 49.8±11.6 years. Mean blood loss and operative time in group (A) were 77.3±9.4 ml and 72.1±7.9 minutes, while in group B, they were 80.7±9.5 ml and 74.8±8.4 minutes with no statistically significant difference between both groups. There were also no statistically significant difference between both groups as regards incidence of dysphagia, clinical scores nor radiological parameters. In conclusion, both zero-profile implant and integrated cage-plate implant have comparable satisfactory clinical and radiological results in treatment of single level cervical disc diseases with little complications.

Double calcaneal osteotomy in treatment of flexible planovalgus foot deformity in ambulatory cerebral palsy. A case series study.

BACKGROUND: The aim of this prospective non randomized case series study was to assess the intermediate-term outcomes of double calcaneal osteotomy (lateral column lengthening and medial slide calcaneal osteotomy) use in ambulatory cerebral palsy with flexible planovalgus feet. METHODS: 16 cases with planovalgus feet were surgically treated by double calcaneal osteotomy and observed over an average of 33.5months. The mean age at the time of surgery was 10.74years. The functional outcomes were assessed clinically and radiologically. RESULTS: There were a statistical improvement of clinical heel valgus and all radiological parameters as regard talar head uncoverage, calcaneal pitch, talo-calcaneal angle, and talus 1st metatarsal angle at the end of follow up period. CONCLUSION: Double calcaneal osteotomy is a good option in the treatment of flexible planovalgus feet in ambulatory cerebral palsy patients.

Scarf versus long chevron osteotomies for the treatment of hallux valgus: A prospective randomized controlled study.

BACKGROUND: The aim of this study is to compare scarf osteotomy and long chevron osteotomy in treatment of hallux valgus deformity regarding operative time, power of correction and complications. DESIGN: A prospective randomized controlled comparative trial. METHODS: 48 cases with hallux valgus were divided randomly in 2 groups (21 treated by scarf and 22 treated by long chevron osteotomy and 5 were missed during follow up), average age 36 years, follow up time was average of 25.9 months. Patients were assessed clinically, radiologically, and functional scoring system of American College of Foot and ankle Surgeons (ACFAS)was used both pre and postoperatively. RESULTS: Operative time was 69min in scarf group compared to 63min to long chevron group, radiological correction showed no statistically significant difference between both groups while functional improvement in ACFAS score was in favour of long chevron group 69.1% compared to scarf group 57.5% CONCLUSIONS: Both osteotomies possess almost identical corrective power of the IMA (intermetatarsal angle) and similar clinical outcomes with slightly shorter operative time and subjective technical simplicity for the long chevron osteotomy.
