Results of Ilizarov external fixator lengthening compared to lengthening and then plating in management of femoral shortening in children.

Femoral shortening in children is a challenging condition with complex functional and psychological implications. We study the results of Ilizarov external fixator (IEF) lengthening compared to lengthening and then plating (LAP) in the management of femoral shortening in children. Forty patients were included in the study and equally divided randomly into 2 groups, in group I LAP was used and in group II lengthening by IEF only was done. The two groups were analyzed for postoperative variables to adjudge the surgical outcomes. The mean follow up time was 24.05 ± 2.99 months, The gained length was 5.60 ± 0.60 cm in group 1 and 5.48 ± 0.64 cm in group II, group I had a shorter external fixator period (3.96 ± 0.22) months, better healing index (24.6 ±2.76) days/cm, earlier complete weight-bearing (5.55 ± 0.78) months than group II. The period of hospitalization for group I was longer more than group II. The complications were less in group I (n=7, 35%) than in group II (n=11, 55%). There was no significant correlation between the healing index with age, also no significant difference was detected between the healing index and gender. There was a significant correlation between the gained length and complete weight-bearing. This study efficiently demonstrates that LAP may be better than lengthening with IEF alone in the management of femoral shortening in children.

Flexible Intramedullary Nail Versus Submuscular Locked Plate with the Cluster Technique in Pediatric Femoral Shaft Fractures Fixation.

Purpose of the Study: The aim of this study is the comparison between the flexible intramedullary nail and submuscular Locked Plate with the cluster technique in fixation of pediatric femoral shaft fractures at the age group between 6 and 12 years old with simple diaphyseal closed or Gustilo open grade I fractures. Methods: Fifty children aged 6-12 years with femoral fractures were enrolled in this study. The children were randomly assigned equally to the two groups for fractures fixation. The follow-up period was 1 year. A comparison of various parameters and outcomes between both groups was documented. Results: No significant differences were detected between both groups regarding the age, gender, affected side, mechanisms of fracture, or fracture classifications. The operative time and radiation time were longer in the plating group, while the amount of blood loss was lesser in the nail group. The patients treated with plating had better results concerning knee range of motion, weight-bearing, malalignment, and length discrepancy, with fewer complications and better functional outcomes. Conclusion: The result of the present study supports the use of submuscular locked plate with cluster technique in the treatment of studied fractures over flexible IMN.

Medial displacement calcaneal osteotomy versus lateral column lengthening to treat stage II tibialis posterior tendon dysfunction, a prospective randomized controlled study.

PURPOSE: Adult-acquired flatfoot deformity (AAFD) requires optimum planning that often requires several procedures for deformity correction. The objective of this study was to detect the difference between MDCO versus LCL in the management of AAFD with stage II tibialis posterior tendon dysfunction regarding functional, radiographic outcomes, efficacy in correction maintenance, and the incidence of complications. PATIENT AND METHODS: 42 Patients (21 males and 21 females) with a mean age of 49.6 years (range 43-55), 22 patients had MDCO while 20 had LCL. Strayer procedure, spring ligament plication, and FDL transfer were done in all patients. Pre- and Postoperative (at 3 and 12 months) clinical assessment was done using AOFAS and FFI questionnaire. Six radiographic parameters were analyzed, Talo-navicular coverage and Talo-calcaneal angle in the AP view, Talo- first metatarsus angle, Talo-calcaneal angle and calcaneal inclination angle in lateral view and tibio-calcaneal angle in the axial view, complications were reported. RESULTS: At 12 months, significant improvement in AOFAS and FFI scores from preoperative values with no significant difference between both groups. Postoperative significant improvements in all radiographic measurements in both groups were maintained at 12 months. However, the calcaneal pitch angle and the TNCA were better in the LCL at 12 months than MDCO, 17̊±2.8 versus 13.95̊±2.2 (p=0.001) and 13.70̊±2.2 versus 19.05̊±3.2 (p<0.001) respectively. 11 patients (26.2%) had metal removal, seven (16.6%) in the MDCO, and four (9.6%) in the LCL. Three (7.1%) in the LCL group had subtalar arthritis, only one required subtalar fusion. CONCLUSION: LCL produced a greater change in the realignment of AAFD, maintained more of their initial correction, and were associated with a lower incidence of additional surgery than MDCO, however, a higher incidence of degenerative change in the hindfoot was observed with LCL.

Minimal invasive para-rectus approach for limited open reduction and percutaneous fixation of displaced acetabular fractures.

INTRODUCTION: Minimal invasive fixation has been reported as an alternative option for treatment of acetabular fractures to avoid blood loss and complications of extensive approaches. Closed reduction and percutaneous lag screw fixation can be done in minimally displaced acetabular fractures. Open reduction is indicated, if there is wide displacement. In this study, we report the use of a mini-open anterior approach to manipulate and reduce anteriorly displaced transverse acetabular fractures combined with percutaneous lag screw fixation. METHODS: This report included eight patients. All had anterior displaced simple transverse acetabular fractures. An oblique mini-incision was made above and medial to the mid-inguinal point, and lateral to the lateral border of rectus abdominis muscle. The external abdominal oblique aponeurosis was incised along its fibres. The arched fibres of internal abdominal oblique were displaced medially above the inguinal ligament to expose and incise the fascia transversalis. Care was taken to avoid injury of ilioinguinal nerve, inferior epigastric vessels, and spermatic cord. The external iliac vessels were palpated and protected laterally. A blunt long bone impactor was introduced through this small incision to manipulate and reduce the fracture under fluoroscopic control. Fluoroscopic guided percutaneous lag screw fixation was done in all patients. RESULTS: The average time to operation was 4 days. Average blood loss was 110mL. Operative time averaged 95min. Maximum fracture displacement averaged 10mm preoperatively and 1.3mm postoperatively. According to Matta score, anatomical reduction of the fracture was achieved in five patients and imperfect in three. Follow up averaged 27 months. Wound healing occurred without complications and fracture union was achieved without secondary displacement in all patients. Average time to fracture healing was 14 weeks. According to the modified Merle d'Aubigné score, functional outcome was good to excellent in all patients. DISCUSSION AND CONCLUSION: Limited open reduction can solve the problem of fracture reduction, which is the main concern in minimal invasive fixation of acetabular fractures. It may help the inclusion of displaced acetabular fractures for percutaneous lag screw fixation. This mini-para-rectus approach has the advantages of minimal soft tissue dissection with the possible anatomical reduction of simple transverse displaced acetabular fractures.
