Single Versus 3-incision Triple Pelvic Osteotomy: Comparison of Clinical and Radiologic Results.

BACKGROUND: Triple pelvic osteotomy (TPO) is indicated when the anatomic and functional realignment of the hip joint is needed. Although the traditional approach for TPO involves a separate incision for ischial cut, there has been a trend for single-incision TPO in recent years. This study aims to compare the clinical and radiologic results of 2 different approaches. METHODS: Forty-two hips of 39 patients treated using TPO with a minimum of 24 months of follow-up were included in our cohort. Demographics, perioperative, and radiologic parameters were evaluated. Harris Hip Score and International Hip Outcome Tool were used for clinical evaluation. RESULTS: A single anterolateral incision approach was used in 18 hips (17 patients), whereas a 3-incision approach was used in 24 hips (22 patients). The mean follow-up was 4.7 years in the 3-incision group and 3.8 years in the single-incision group (P=0.43), with mean surgery age at 8.7 years (range, 5.4 to 12) for single-incision and 9.7 years (range, 7.7 to 11.7) for 3e-incision (P=0.22). There were no significant differences observed between the 2 groups concerning radiographic measurements, complications, and functional scores. The mean surgical time was 118.6 minutes in the single-incision group and 97.9 minutes in 3-incision group (P=0.036). Mean intraoperative blood loss was 181.7 ml in the single-incision group and 243.4 ml in 3-incision group (P=0.028). Three-incision group demonstrated significantly higher intraoperative blood loss, leading to lower hemoglobin values (P=0.042). CONCLUSION: The single-incision TPO demonstrated similar outcomes compared with the traditional 3-incision approach in terms of radiologic correction and functional improvement. The single-incision technique exhibited advantages such as reduced intraoperative blood loss and potential benefit of decreased pain due to fewer scars. However, it required a longer surgical time compared with the 3-incision approach. Surgeons should consider patient-specific factors and their expertise when selecting the most appropriate approach for each case. LEVEL OF EVIDENCE: Level III-retrospective comparative series.

Does the Sleeper Plate Application for Temporary Epiphysiodesis Make Life Easier or Complicated? Increased Risk of Tethering.

BACKGROUND: The present study aims to investigate the frequency of recurrence and tethering effect after only metaphyseal screw removal (sleeper plate technique) compared with the conventional complete plate removal in the treatment of lower extremity deformities with guided growth surgery. METHODS: Seventy-two patients (107 limbs) treated by an 8-plate hemiepiphysiodesis technique around the knee joint were evaluated. After the desired correction, only metaphyseal screw was removed (sleeper plate group) in 35 limbs (25 patients), whereas both screws and plate were removed (plate removal group) in 72 limbs (47 patients). An increase of 5 degrees or more in joint orientation angles in the direction of the initial deformity was considered as recurrence. The rate of rebound, tethering, and maintenance of correction in groups was analyzed at the latest follow-up (mean of 49 mo). RESULTS: The mean age of the patients was 97 months (range: 80 to 129 mo) at the time of index surgery. After a mean of 49 months (range: 16 to 86), 17 (48.5%) limbs maintained the desired stable correction in the sleeper plate group compared with 59 stable limbs (72.2%) in the plate removal group ( P <0.001). There was no statistically significant difference regarding recurrence between the sleeper plate group and the plate removal group (34.3% vs. 27.8%, respectively) ( P =0.216). Reinsertion of the metaphyseal screw was possible 8/12 limbs, and the remaining 4 limbs underwent further surgeries. There were 6 limbs (17.3%) of tethering in the sleeper plate group, and 4/6 limbs required further corrective surgeries. The remaining 2 limbs with slight tethering did not require further surgeries. CONCLUSIONS: Removing only metaphyseal screw increases the risk of tethering. In addition, reinsertion of the screw may not be possible in all cases due to bony growth, and further corrective surgeries may be necessary. Close follow-up is required if the sleeper plate technique is to be applied. LEVEL OF EVIDENCE: Level III.

Complex rigid foot deformity correction with hexapod external fixator system.

PURPOSE: Complex rigid foot deformities include three-plane deformities and usually presents with poor soft tissue coverage. In the last decades, gradual correction with computer-assisted fixator became an appropriate option for the treatment rigid foot deformities. This study aims to report our experience about treatment of complex foot deformities using Smart Correction fixator system®. METHODS: We retrospectively analyzed 13 complex rigid foot deformities of ten consecutive patients treated with Smart Correction fixator system® from 2016 to 2020. Primary outcomes were classified as good, fair, and poor according to previously determined criteria. The outcomes were also assessed with The Manchester-Oxford Foot Questionnaire (MOXFQ). Non-parametric analysis (Wilcoxon test) for continuous variables and the Fisher's exact test for categorical variables were used. RESULTS: Plantigrade foot was achieved in all patients after correction program. Supramalleolar osteotomy was applied in nine feet, midfoot osteotomy was applied in two feet, hindfoot osteotomy was required in one foot, and only soft tissue distraction performed in two feet. Two patients had recurrent deformity managed by further acute corrections. The mean MOXFQ scores improved from 72.7 preoperatively to 24.8 at last follow-up. CONCLUSIONS: Present study shows that SCF the reliable option for the treatment of complex foot deformities, which also facilitates three-plane correction and concomitant lengthening with gradual soft tissue balance.
