Purpose Congenital dislocation of the knee (CDK) is a relatively rare condition. It may occur as an isolated deformity, it may be associated with musculoskeletal anomalies such as developmental dysplasia of the hip and clubfoot, or it may occur as part of a syndrome such as arthrogryposis multiplex congenita or Larsen syndrome, or it may occur in paralytic conditions such as meningomyelocele. Treatment options include serial casting, percutaneous quadriceps recession (PQR) and V-Y quadricepsplasty (VYQ). The aim of this study is to evaluate the medium-term results of PQR and VYQ, and to set a protocol of management for CDK based on a modified grading system. Methods Eleven infants with 21 CDK were treated at our unit. Five knees were treated with serial casting, 12 knees with PQR and four knees with VYQ. Follow up averaged 41 months. Results Twelve knees achieved excellent results, seven knees achieved good results and two knees achieved fair results. Conclusion A modified grading system for CDK is introduced. Based on this, we recommend the following. Serial casting is performed in patients with GI CDK. In GII CDK in neonates (babies up to the age of 1 month) serial casting is started. A maximum of four weekly manipulations and castings are attempted. If a range of flexion [90°i s achieved, serial casting is continued; if range of flexion remains \90°it is necessary to proceed to PQR. In babies older than 1 month when first seen; PQR is performed from the start. VYQ is indicated in patients with GIII CDK or in recurrent cases.

The aim of the study is to find the correlation between vitamin D level and the severity of slippage and bilateral development in slipped capital femoral epiphysis (SCFE) cases if any. Thirty-nine patients with moderate-severe stable SCFE were evaluated regarding their vitamin D level and to which extent the severity of vitamin D deficiency, if present, can be correlated with the severity and bilaterality of the slip. Vitamin D serum level was assessed pre- operatively for all patients. In case of deficiency, the patient underwent in situ pinning unless performed before his/her presentation. Alongside, he/she received a vitamin D course until correction prior to the definitive surgery (Imhäuser osteotomy with osteochondroplasty) 6-12 weeks after. Thereafter, osteotomy healing and physis closure were monitored radiologically. Results show that all patients but one had vitamin D deficiency, with an average of 14.39 ng/mL, necessitating vitamin D therapy before proceeding to the definitive surgery. No correlation existed between vitamin D level and Southwick angle severity with a p-value of 0.85. A negative correlation existed between vitamin D level and bilaterality, but not statistically significant (p-value 0.192). Patients’ osteotomy healing was uneventful, and physeal closure was achieved in all the cases that had in situ pinning. We conclude that the severity of Vitamin D deficiency could be linked to the bilateral development of SCFE but not the severity of slippage. Treatment of Vitamin D deficiency facilitates physeal closure.

Conjoined twining is one of the most fascinating and challenging situations which a pediatric surgeon may face in his career. Only few surgeons may have the opportunity to share in separation of such cases. In this report, we aim to share our experience with the successful separation of ventrally fused male conjoined twins (omphaloischiopagus). The case was thoroughly studied via preoperative cross-sectional imaging modalities (magnetic resonance imaging [MRI] and computed tomography [CT] angiography), complemented by data obtained from reviewing similar cases in the literature. A clear delineation of the complex anatomy was achieved preoperatively which proved to be well consistent with the operative findings. A detailed description of the operative procedure to divide/redistribute the shared abdominal/pelvic organs between both twins is provided. To the best of our knowledge, this is the first report to describe the detailed and unique internal anatomy of a common central phallus associating ischiopagus conjoined twins. The penis was centrally located in the perineum in between both twins with an open urethral plate. This common phallus had a peculiar configuration with four crura anchoring ischial bones of both twins together.

The aim of the study is to assess the safety and efficacy of Imhäuser osteotomy combined with osteochondroplasty in the treatment of moderate-severe stable slipped capital femoral epiphysis (SCFE) on short-term basis. Nineteen patients (20 hips) with moderate-severe stable SCFE were surgically treated by Imhäuser osteotomy combined with osteochondroplasty and followed up for 3–4 years. The cases aged between 12 and 18 years at the time of surgery and complained of a variety of symptoms and signs that included pain, limping, limited range of motion (ROM), and/or abductor weakness. The outcomes were assessed using clinical and radiological parameters as well as functional outcome measures: “Harris hip score” (HHS) and “The Western Ontario and McMaster Universities Osteoarthritis Index” (WOMAC). There were statistically significant improvements in flexion, internal rotation, and abduction ROM. HHS and WOMAC improved significantly with final follow-up scores at 86.76 and 6.4%, respectively. The radiological parameters showed significant improvement regarding Southwick angle (mean 12.8°), alpha angle of Nötzli (mean 29.85°), Hilgenreiner epiphyseal angle (mean 37.65°), neck shaft angle (mean 140.63°), and acetabulo-trochanteric distance (median14.1 mm) at the end of follow-up period. Imhäuser osteotomy combined with osteochondroplasty is a good option in moderate-severe stable SCFE treatment.

Infantile coxa vara can be corrected by valgus osteotomies, but recurrence is high. Achieving an Hilgenreiner epiphyseal angle (HEA) of 40° or less prevents recurrence. In this study, Pauwels' osteotomy is stabilized using a rigid method of fixation. The aim of the study is to confirm previous reports regarding the correction of the physeal inclination to 40° or less to prevent recurrence. Thirty-one hips with infantile coxa vara were subjected to an intertrochanteric Y-shaped valgus osteotomy. In 27 hips, the HEA was corrected to 40° or less and none had a recurrence. This study confirms previous recommendations regarding the correction of HEA to 40° or less to avoid recurrence.

Background/Aims: Patients with osteogenesis imperfecta (OI) present with various degrees of short stature and nutritional disorders. Thus, we aimed to evaluate anthropometric and nutritional parameters in OI children and their variability among various types. Methods: Eighty-four patients with OI (types I, II, and IV) were subjected to the following anthropometric measurements: standing height (Ht), sitting height (SH), arm span, weight (Wt), and head circumference (HC), with calculation of Ht, SH, Wt, body mass index (BMI), and HC standard deviation scores (SDSs), and relative arm span. Triceps skinfold thickness (TSFT), subscapular skinfold thickness (SSFT), and mid upper arm circumference (MUAC) were measured, as well as dietary intake of macronutrients and calcium; also, energy requirements were calculated. Results: Ht SDS was reduced in OI-III and OI-IV compared to OI-I; SH SDS was reduced in OI-III compared to OI-I. HC SDS was more increased in OI-III than in OI-I and OI-IV. BMI SDS correlated with TSFT, SSFT, and MUAC. OI-III patients had the highest percentage of energy intake. The frequency of low macronutrient and calcium intake was highest in OI-III, while the frequency of low fat intake was highest in OI-I. Conclusions: Anthropometric and nutritional parameters differ among OI types. Assessment of anthropometric measurements and nutritional status in OI patients is important.

Background:Literature is confusing regarding grading and treatment of flexion deformities of wrist and fingers in spastic cerebral palsy (CP). The most established classification is that described by Zancolli; unfortunately, it has its shortcomings which we experienced in the beginning of our approach to manage this rather difficult deformity. We thus modified Zancolli's classification and developed a classification system and treatment protocol.Materials and Methods:Thirty patients with spastic CP were operated upon due to flexion deformity of the wrist and fingers and were included in this study. Age ranged from 4 to 14 years, average 7 years. There were twenty boys and ten girls.Results:The average followup was 18 months (range 9 months - 3 years). The power of wrist dorsiflexion, the “House's classification of upper extremity functional use” and the clinical assessment of hand function were used for evaluation; they improved in all patients and this improvement was statistically significant. In all patients, cosmetic appearance improved without any residual flexion deformity.Conclusion:This study introduces a new grading system for flexion deformity of wrist and fingers in spastic CP that correlates with severity of the condition and allows a treatment protocol to be established.

A total of 35 children with Erb's palsy and shoulder abduction of < 90° underwent transfer of teres major. In 18 cases (group 1) a trapezius transfer was added (combined procedure). In 17 cases (group 2) teres major transfer was carried out in isolation (single procedure). The mean gain in abduction was 67.2° (60° to 80°) in group 1 and 37.6° (20° to 70°) in group 2, which reached statistical significance (p < 0.001). Group 2 was further divided into those who had deltoid power of < M3 (group 2a) and those with deltoid power ≥ M3 (group 2b). The difference in improvement of abduction between groups 2a and group 2b was statistically significant (p < 0.001) but the difference between group 2b and group 1 was not (p = 0.07). We recommend the following protocol of management: in children with abduction ≥ 90° a single procedure is indicated. In children with abduction < 90°: a combined procedure is indicated if deltoid power is < M3 and a single procedure is indicated if deltoid power is ≥ M3. If no satisfactory improvement is achieved, the trapezius can be transferred at a later stage.
