Background Hallux valgus deformity is a common sequel of spastic cerebral palsy. Methods Twenty ambulatory patients (24 feet) suffering hallux valgus deformity, with painful forefoot and restricted footwear, secondary to spastic cerebral palsy acquired perinatally, were treated with great toe metatarsophalangeal (MTP) arthrodesis using percutaneous K-wires for fixation. The mean age at the time of surgery was 16.2 years (range 14-18 years). They were retrospectively evaluated for the results after arthrodesis at a mean interval of 3 years and 4 months (range 3-4 years) by physical examination and radiographs. Results All patients had a stable painless aligned great toe, with \10°valgus, \20°dorsiflexion and neutral rotation after arthrodesis, evidenced by improvement in pain, cosmesis, functional activity, footwear, callosities and hygiene, as well as by significant improvement in the measures of the MTP and the intermetatarsal angles (IMA) by postoperative radiographs. Neither non-union (pseudoarthrosis) nor recurrence of the deformity developed. Complications included superficial wound slough in a single case. Using the modified American Orthopaedic Foot Ankle Society (AOFAS) Hallux Metatarsophalangeal-Interphalangeal Scale, 18 feet (75%) were classified as excellent and six feet (25%) as good. Neither fair nor poor cases were recorded. Conclusion Hallux valgus deformity in adolescents with spastic cerebral palsy is best treated by great toe MTP arthrodesis to improve segmental foot malalignment and dynamic foot deviation.

INTRODUCTION Adduction of the forefoot is the most common residual deformity in idiopathic clubfoot. The 'bean-shaped foot', which is a term used to describe a clinical deformity of forefoot adduction and midfoot supination, is not uncommonly seen in resistant clubfoot. SUBJECTS AND METHODS Fifteen children (20 feet) with residual forefoot adduction in idiopathic clubfeet aged 3-7 years were analyzed clinically and radiographically. All of the cases were treated by double column osteotomy (closing wedge cuboid osteotomy and opening wedge medial cuneiform osteotomy) with soft tissue releases (plantar fasciotomy and abductor hallucis release), to correct adduction, supination and cavus deformities. Pre-operative measurements of certain foot angles were compared with their corresponding postoperative values. RESULTS A grading system for evaluation of the results using a point scoring system was suggested to evaluate accurately both clinical and radiographic results after a follow-up period of an average of 2.3 years. Eight feet (40%) had excellent, eight (40%) good, three (15%) fair, and one (5%) poor outcome. There was no major complication. There was significant improvement in the result (P > 0.04). CONCLUSIONS Double column osteotomy can be considered superior to other types of bone surgeries in correction of residual adduction, cavus and rotational deformities in idiopathic clubfoot.

Background:Rachitic genu varus is one of the common conditions among the Egyptian children, despite the shinning sun of Egypt all the year.Purpose:The aim of the study was to estimate the incidence of rachitic genu varus among the Egyptian children, and to assess the risk factors contributing to it.Patients and Methods:This prospective study recruited a total of 250 consecutive children, being 130 males and 120 females, with rachitic bow legs or genu varus, between 2 - 4 years of age, together with 250 controls of the same age group, out of a total number of 1900 children with other types of rickets, and other children's orthopaedic diseases, who presented to the National Institute of Neuromotor System in Egypt between September 2014 to September 2015. The cases and the controls were subjected to clinical, laboratory biochemical, and plain radiographic examinations. Their parents were subjected to epidemiological, maternal, and nutritional questionnaires.Results:The calculations revealed high incidence (13.1%) of rachitic genu varus. The risk factors were low socioeconomic status, insufficient family income, poor housing conditions, lack of exposure to sunlight due to cultural practices, sole breast feeding, and inadequate supplementation of vitamin D to the children and the pregnant women. The p value was <0.05.Conclusion:Vitamin D deficiency rachitic genu varus is a multifactorial condition in Egypt. Raising the standard of living, level of education, housings, and dietary supplementation of vitamin D to the pregnant women and infants are the solution.

Objectives We analyzed several radiological features of the facial recess to correlate them with the intraoperative findings to highlight the most reliable predictors of posterior tympanotomy difficulty. Study Design Retrospective observational cohort study. Setting Multicenter study at tertiary referral institutions. Methods We included 184 pediatric patients who underwent cochlear implantation through the posterior tympanotomy approach. The correlation was attempted between 8 radiological features in the preoperative high-resolution computed tomography scan and intraoperative surgical difficulty. Results Posterior tympanotomy was straightforward in 136 (73.9%) patients. In contrast, it was challenging in 48 (26.1%) patients. The facial recess was aerated in 74.5% of patients. The mean (SD) posterior tympanotomy depth was 3.98 (0.867) mm. The mean (SD) chorda-facial angle was 27.67° (3.406°). The mean (SD) chorda-facial to stylomastoid length was 3.898 (0.6304) mm. The mean (SD) facial nerve second genu angle was 94.54° (6.631)°. Deep-unaerated facial recess wall was associated with the most difficulty. There was a statistically significant difference in the unchallenging and challenging posterior tympanotomy groups regarding the surgical duration ( P < .0001). Conclusions According to this analytic study, the chorda-facial angle, the facial recess aeration, and the chorda-facial to stylomastoid length were respectively the strongest preoperative radiological predictors of the surgical difficulty of posterior tympanotomy during cochlear implantation. Chorda-facial angle <25.5° was associated with difficult posterior tympanotomy. The oblique parasagittal cut was essential for the radiological analysis of the facial recess.
