N2  - Background: Complex pediatric lower limbs deformities represent a challenging 
situation to manage; starting from different etiologies, preoperative planning & 
surgical corrections with possible complications and relapses. We hypothesized 
that simple monolateral fixator can effectively correct lower limb deformities that 
doesn’t involve limb length discrepancy. 
Aim: To evaluate the use of monolateral fixator in correction of multiplanar 
deformities regarding radiological correction, clinical progression and possible 
complications. 
Methods: An interventional clinical trial was done in Abu Elreesh children’s 
hospitals on 25 patients with 39 limbs that were operated on. Patients were divided 
into 4 main groups representing pattern of deformity presentation/convenience. 
Group I (Genu varum with internal rotation), Group II (Genu valgum with external 
rotation), Group III (Neglected hemiepiphysiodesis) & Group IV (Other 
combinations). The outcomes were evaluated using long lower limbs standing 
radiographs preoperatively and at the final assessment. The variables of interest 
were MAD, mLDFA, MPTA, LDTA, SMAA, PDFA, PPTA, tibial torsion& 
femoral version. 
Results: The median age of the studied group was 13 years, males and females 
were almost the same 12(40%), 13(52%) respectively. We operated upon 41 limbs 
involving 69 segments. Superficial pin tract infection affected (23) 56% of the 
limbs. The median pre-op MAD was 6.3cm and post-op 0.4cm. Pre-op SMAA 
median was -10º and post-op 0º, and the median of the tibial torsion degree 
changed from pre-op 40º to post-op 18º. 
Conclusion: The simple monolateral fixator can be an effective system for 
correction of multiplanar lower limb deformities without limb length discrepancy; الجانب تجعله خيارًا جذابًا لتصحيح تشوه الأطراف السفلية المعقدة فقط في حالة عدم وجود تباين في طول الطرف. إنه سريع وأكثر تحملاً وأقل إيلامًا من نظام إليزاروف و TSF ، ويمكن إجراؤه في عظم الفخذ الثنائي دون إزعاج كبير للمرضى على عكس مثبتات الحلقة ومزايا الاستشفاء القصير ، ووقت قصير للشفاء ، ومضاعفات أقل ، وأرخص بكثير ، ومتوفر بسهولة و مع منحنى تعلم أسرع بكثير من Ilizarov أو TSFومع ذلك ، لا يمكن تطبيقه في حالة التشوه المعقد مع اختلاف طول الأطراف
