Modified triple pelvic osteotomy for residual acetabular dysplasia through double incisions: Technical note and review of short-term results.

PURPOSE: To assess validity, safety, and efficacy of the modified triple pelvic osteotomy (TPO) approach for correction of residual acetabular dysplasia. METHODS: This is a retrospective case series conducted on 15 hips in 15 patients from 2019 to 2023 with residual acetabular dysplasia treated by modified TPO as described by Tonnis with two modifications. The first modification is using a single medial incision for pubic and ischial cuts (the Vladimirov modification). The second modification is having the ischial cut closer to the acetabulum (Li modification) allowing free movement of the acetabular fragment for better femoral head coverage. The mean age at the time of surgery was 11.85 years, (range 8-23). Cases presenting were 10 males (66.7%) and 5 females (33.3%). The mean follow-up period was 36.533 months (24-60 months). RESULTS: Our study revealed significant clinical and radiological improvement. The CE angle improved from a mean value of 10° (range 2-17) pre-operatively to 32.785° (range 18°-40°) post-operatively. The AI improved from a mean value of 32° pre-operatively to a mean value of 13.89° post-operatively. HHS increased from a preoperative mean value of 74.80° to a post-operative mean value of 90.67°. Also, there was a significant improvement in ROM (abduction and internal rotation). LLD improved from a mean value of 2.60 cm preoperatively to a mean value of 0.37 cm postoperatively. Delayed union was found in 3 cases. No cases of osteonecrosis or neurovascular complication were encountered in our study. CONCLUSION: The modified TPO technique using dual incisions can be considered safe and effective, providing adequate coverage of the femoral head in acetabular dysplasia with less surgical time, satisfactory functional outcomes, and minimal complications. LEVEL OF EVIDENCE: IV.

Naviculectomy With Limited Soft-Tissue Releases as a Third Way Beyond Manipulative Treatment and Extensive Soft-Tissue Releases for Ambulatory Children With Complex Congenital Vertical Talus: A Technical Note.

We investigated the radioclinical outcomes of naviculectomy and limited/tailored soft-tissue releases in a short series of ambulatory children with complex/intractable congenital vertical talus subsets namely neglected, multiple operated, and recurrent patients. We postulated that this technique will yield satisfactory radioclinical outcomes and minimal complications because it avoids extensive surgical release/trauma that is otherwise classically recommended for complex congenital vertical talus. The cohort consisted of 5­4 boys and 1 girl­complex congenital vertical talus children with neglected, multiple operated, and/or recurrent subsets. Patients were included if manipulative casting techniques were deemed unlikely to produce a plantigrade foot. Patients underwent naviculectomy with variable on-demand limited soft-tissue releases. Two patients had bilateral affection and 2 had a nonidiopathic cause. The mean age was 5.2 years (4-6.25) and mean follow-up was 2.3 years (1-3). We reported satisfactory outcomes as per foot posture, function, overall parent satisfaction including pain and radiography per lateral views of talar-axis-first metatarsal base angle on the short/intermediate term. Whereas manipulative casting is unlikely to yield lasting outcomes in ambulatory children with complex subsets of congenital vertical talus, extensive surgical soft-tissue releases have unfavorable long-term complications. As a substitute, naviculectomy as a form of resection arthroplasty created a practical and affordable third way between manipulative casting with or without minimally invasive surgery and the extensive surgical soft-tissue releases on the short-to-intermediate term. LEVEL OF EVIDENCE: Level IV case series.

Growth Modulation for Knee Coronal Plane Deformities in Children With Nutritional Rickets: A Prospective Series With Treatment Algorithm.

To report prospectively the radioclinical outcome of guided growth surgery for coronal plane deformities around the knee in young children with nutritional rickets on the intermediate term, to assess the responsiveness of torsional deformities of the tibias to guided growth regarding function and objective clinical parameters, and to propose a treatment algorithm. Methods: Fifty children (male:female, 27:23) with knee coronal plane deformities (knees:physes, 86:99), (varum:valgum, 51:35) secondary to nutritional rickets were subjected to femoral and/or tibial temporary hemiepiphysiodesis using a two-hole 8-plate. The mean age at implantation was 3.8 ± 1.5 years (range 2.5 to 5). The mean follow-up was 2.8 years (range 2 to 4). All children received a standing full-length AP radiographs of both lower limbs in neutral rotation to measure the mechanical axis deviation, tibiofemoral angle, and joint orientation angles. Tibial torsion was objectively assessed by measuring the bimalleolar axis. Results: The radiologic measurements, tibiofemoral angle, mechanical axis deviation, mechanical lateral distal femoral angle, medial proximal tibial angle, and Hilgenreiner-epiphyseal angle, showed a highly statistically significant improvement (P ≤ 0.001). Radiographic outcomes correlated with their clinical counterparts. The mean duration of correction of the mechanical axis was 10.8 ± 2.4 months (7 to 21). The mean follow-up for rebound of the deformity was 1.5 years (range 1 to 3). Conclusion: The radioclinical outcome is rewarding with a tolerable complication profile. The mechanical complications were mostly related to lengthy implant retainment encountered in severe deformities. Internal tibial torsion seems profoundly responsive to correction of coronal plane deformity. And, derotation osteotomies are rarely justified. Our proposed algorithm may be used as a decision-taking guide for achieving the desired growth modulation in a more efficient manner.

Bilateral horizontal salter osteotomies with anterior symphyseal closure using a nylon tape in the treatment of exstrophy of the bladder.

The aim of this case series study is to describe the orthopedic management of bladder exstrophy and to report on the intermediate-term outcomes following bilateral horizontal Salter osteotomies with anterior symphyseal closure using a nylon tape. This retrospective study included seven patients (five boys and two girls) who underwent bilateral horizontal osteotomies after reconstruction of the urogenital deformity using the Cantwell-Ransley technique and symphyseal closure by nylon tape number 2-5. the age range was between 7 months and 8 years (median age = 17 months). Three patients had recurrent bladder exstrophy after they underwent "ramotomy" early in their life, whereas four were operated primarily. All patients were followed up over 2 years, with a mean follow-up duration of 3.27 years (2-5 years). Petrie cast was applied, with both legs abducted and internally rotated till bony union had been achieved. This allowed free handling of the wounds and catheters. Removal of k-wires was performed in an outpatient clinic after the complete union of bony osteotomies had been achieved (6-8 weeks). Satisfactory bladder closure was achieved in all patients. None of the patients had a bone infection or nonunion at the osteotomy sites. No postoperative wound dehiscence has occurred for up to 5 years. The foot progression angle improved from 37°-70° (median = 45°) preoperatively to 0°-15° (median = 5°) postoperatively. Symphyseal diastasis was closed well in all of our patients in postoperative plain radiography compared with 5.8-11 cm (median = 8.2 cm) diastasis preoperatively. One patient had a superficial wound infection. Another patient had a sutured bladder neck by a nylon tape during the symphyseal closure. Bilateral horizontal Salter osteotomies with anterior symphyseal closure using nylon tape are safe and effective in the management of bladder exstrophy, especially in older children and in extreme diastasis (> 6 cm); with improvement in the gait as it corrects the acetabular external rotation.

Femoral and Dega osteotomies in the treatment of habitual hip dislocation in Down syndrome patients - is it efficient or not?

PURPOSE: The purpose of this case series study is to report on the intermediate-term outcomes following a femoral varus derotational osteotomy (FVDO) performed in conjunction with a Dega osteotomy (DO) in management of hip -instability in Down syndrome (DS) patients. METHODS: Ten hips in seven children with DS suffering from hip dislocation were included. All patients included in this study had hip dislocation in the habitual phase and painless mobile hip to full abduction. All patients were firstly subjected to FVDO. An additional DO was added if intraoperative assessment demonstrated posterior instability. The mean age at time of surgery was 5.6 years (3 to 7). There were three male and four female patients. All patients were followed up after two years with a mean follow-up of 3.27 years (2 to 5). All operations were performed by the first author. RESULTS: There was improvement of neck shaft angles (130° to 175°, median = 160° preoperatively, to 120° to 140°, median =130° postoperatively). The Shenton line was restored in all our cases. There was also improved percentage of the femoral head uncovered by the lateral wall of the acetabulum (25° to 100° with median = 45° preoperatively, to 0° to 15° with median = 5° postoperatively) and improved posterior acetabular coverage, which was assessed by CT. CONCLUSION: FVDO combined with DO without -capsulorrhaphy is efficient in the management of hip instability in DS, as it corrects hip biomechanics and increases posterior acetabular coverage. LEVEL OF EVIDENCE: IV - retrospective case series.

Current paediatric orthopaedic practice in hereditary multiple osteochondromas of the forearm: a systematic review.

INTRODUCTION: This systematic review aims to answer three research questions concerning the management of hereditary multiple osteochondromas of forearm in children: What is the best available evidence for the currently employed surgical procedures? What patient characteristics are associated with better prognosis? What disease characteristics are associated with better prognosis? METHODS: We searched the literature using three major databases with no publication date restrictions. To enhance search sensitivity and maintain precision we used keywords/subject terms correlating with patient population, problem and interventions. We used strict inclusion/exclusion criteria to improve validity evidence. RESULTS: The search process yielded 34 eligible studies with a total of 282 patients (315 forearms). We comprehensively analysed study and patient demographics and interventions and outcomes. Eleven studies (32%) had a long-term follow-up and 31 studies (91%) were retrospective. Of the total number of forearms, ulnar lengthening +/- associated procedures was used in 210 forearms (66.7%), isolated osteochondroma excision in 65 forearms (20.6%) and isolated distal radius hemiepiphysiodesis in 15 forearms (4.7%) among others. DISCUSSION: Ulnar lengthening can restore radiologic anatomy, improve appearance and to a lesser extent objective clinical parameters like joint range of motion on the short/intermediate term. Isolated osteochondroma excision can relief pain and satisfy cosmetic concerns occasionally. There is poor evidence to suggest that surgery improves quality of life or function. Predictors of surgical success in regard to patient and disease characteristics remain elusive. Natural history and prospective randomized control studies where the control group receives no treatment should be rethought. They have the potential for bias control and identification of the ideal surgical candidate. The complex interplay between the confounding variables has undermined the capability of most studies to provide well-grounded evidence to support and generalize their conclusions. Valid quality of life scales should supplement objective outcome measures.
