Functional and radiographic assessments of post-traumatic asymmetrical ankle osteoarthritis treatment using supramalleolar osteotomies.

PURPOSE: This study's objective is to assess the effectiveness of supramalleolar osteotomies (SMOT) in the treatment of asymmetrical ankle osteoarthritis in terms of the improvement in alignment assessed radiographically and its impact on symptoms measured by the American Orthopedic Foot and Ankle Society ankle-hindfoot score (AOFAS ankle-hindfoot score). METHODS: Twelve patients participated in this prospective observational case series study. Standing anteroposterior, true lateral, and mortise views radiographs were taken. For preoperative planning, the lateral distal tibial angle (LDTA), talar tilt (TT), talocrural angle (TCA), and anterior distal tibial angle (ADTA) were all measured. A medial opening wedge osteotomy mainly was used to treat the varus arthritis ankle. A further oblique fibular osteotomy is frequently necessary. RESULTS: The male-to-female ratio was 3:1, and the mean age of the patients was 26.25 ± 13.032 years. There were highly statistically significant differences between pre-and post-operative AOFAS ankle-hindfoot score (p < 0.001). Statistically significant differences concerning ankle range of motion (p = 0.002, < 0.001) of dorsiflexion and planter flexion were detected. Comparison between pre-and post-operative patients' radiology characteristics shows statistically significant differences concerning TT (p = 0.016) and LDTA (p = 0.046). CONCLUSION: SMOT is very effective in the treatment of post-traumatic ankle osteoarthritis and postpones ankle fusion or total ankle replacements. This surgery significantly improves functional and radiological outcomes as well as the range of motion in the ankle. Meticulous preoperative planning by radiological measurements of different angles around the ankle is considered the crucial factor in success of that operation.

Surgical management of paediatric pelvic fractures: a prospective case series and early experience from a level one Egyptian trauma centre.

PURPOSE: We aimed to report our early experience treating paediatric pelvic fractures (PPF) surgically, reporting on indications, outcomes, and complications. METHODS: Patients aged 0-15 with PPF treated surgically at a level I trauma centre were included prospectively between 2016 and 2018. Fractures were classified according to AO/OTA classification system. Functional evaluation was performed using a modification of the Majeed functional scoring system. Radiological evaluation of vertical and posterior displacement was performed according to Matta and Tornetta criteria and the method described by Keshishyan et al. for assessing pelvic rotational asymmetry. RESULTS: We included 45 patients (77.8% males and 22.2% females), with a mean age of 9.53 ± 3.63 and 19.87 ± 8.84 months of mean follow-up. The functional outcome was excellent in 42 (93.3%) patients, good in two (4.4%), and fair in one (2.2%). Radiologically, the vertical displacement improved from 5.91 ± 4.64 to 3.72 ± 2.87 mm (p-value 0.065), the posterior displacement improved from 7.87 ± 8.18 to 5.33 ± 13.4 mm (p-value 0.031), and the symphyseal diastasis improved from 9.88 ± 7.51 mm to 7.68 ± 3.18 mm (p-value 0.071). Residual pelvic asymmetry improved from 1.2 ± 0.61 to 0.8 ± 0.7 (p-value 0.001). Complications occurred in 21 (46.7%) patients, 11 (24.4%) pin tract infection, six (13.3%) limb length discrepancy, two (4.4%) prominent metals, one (2.2%) subcutaneous haematoma, one (2.2%) infected ISS. CONCLUSIONS: We achieved acceptable functional and radiological outcomes after surgically treating a group of patients with PPF, which was relatively safe with minimal complications. The proper approach and fracture fixation tool should be tailored according to the fracture classification and the presence of associated injuries.

Management of anterior associated types of acetabular fractures utilizing the modified Stoppa and the pararectus approaches: a prospective cohort study and early experience from a level one Egyptian trauma centre.

PURPOSE: This study aimed to report the early experience (radiographic, functional, and complications outcomes) from an Egyptian (North African) level one trauma centre after utilizing the modified Stoppa and the pararectus approaches to manage anterior-associated types of acetabular fractures. PATIENTS AND METHODS: Between January 2014 and April 2018, 63 patients (40 males and 23 females) with a mean age of 33 ± 11.5 were included, 45 patients were treated through the modified Stoppa (group A), and 18 through the pararectus approach (group B). RESULTS: At a mean follow-up of 32.11 ± 15.36 months (range 12 to 64), 56 patients (43 group A and 13 group B) were evaluated. The post-operative anatomical reduction was achieved in 44 (78.6%) patients. At the last follow-up, Matta radiological outcome grades were excellent and good in 50 (89.2%) patients, fair and poor in six (10.8%). The mean Harris Hip Score (HHS) was 92.6 ± 7.6; the mean modified Merle D'Aubigné (MMD) score was 16.5 ± 1.5. Excellent functional outcome was reported in 42 (75.0%) and 25 (44.6%) patients according to HHS and MMD scores, respectively. There are four (7.1%) intra-operative iatrogenic complications (two in each approach), three (5.3%) vascular injuries (two in group B and one in group A), and one (1.8%) bladder injury in group A. CONCLUSION: Employing less-invasive anterior approaches for managing anterior associated types of acetabular fractures proved efficiency and safety. Good to excellent radiological and functional outcomes were achieved, with no significant difference between both approaches.
