RESUMO
Objective The study was aimed to compare the outcome of Salter's and Pemberton's osteotomy to achieve adequate acetabular coverage in the open reduction of developmental dysplastic hips (DDH). The functional outcome was evaluated as measured on Bhatti's Functional Score System (BFSS). Patients and methods The study includes 60 children with 82 hips of developmental dysplasia in walking-age children. They were operated on for open reduction and Salter's or Pemberton's pelvic osteotomy to achieve concentric anatomical reduction with good anterolateral coverage of the femoral head. Patients for Salter's and Pemberton's osteotomies were randomly selected. Preference was given to Pemberton's osteotomy in cases with double/irregular acetabulum and in bilateral DDH. All patients were operated on by a single surgeon from January 2014 to December 2016 and were followed up till June 2020. The overall radiological outcome was assessed on Severin's classification, comparing the pre and postoperative acetabular index (AI) and the clinical outcome on Bhatti's Functional Score System. Results The overall functional behavior on Bhatti's Functional Scoring revealed satisfactory outcome (excellent and good) in 73.17% (60/82) hips. On the radiological evaluation, 85.36% (70/82) hips achieved satisfactory development of hips (Severin Class IAB and IIAB) while 12.19% (10) hips developed a moderate deformity of the hip (Severin Class III; p>0.05). Comparing outcomes in both the Pemberton and Salter groups, the acetabular index significantly reduced after both procedures (p<0.05), however, the Pemberton group was more effective than the Salter group. Avascular necrosis (AVN) of Caput Femoris was noticed in 9.57% (8) hips, subluxations in 2.43% (2) hips, and impingement and stiffness in 12.19% (10) hips. Salter's group had more numbers of AVN and subluxations as compared to the Pemberton group, whereas impingement and stiffness were more in Pemberton's but none in the Salter group. Conclusion The hips with Pemberton's acetabuloplasty exhibited better acetabular coverage and progressive development of hips as compared to Salter's osteotomy group. Both groups, however, behaved equally on functional assessment with Bhatti's Functional Score System. The risk of subluxation and AVN was found higher in Salter's group, and femoroacetabular impingement in Pemberton's group. Pemberton's osteotomy was the best option for a single-stage open reduction in bilateral DDH in terms of less risk of bleeding, good stability, better postoperative pain control, and a second surgery to remove transfixation K-wires.
RESUMO
OBJECTIVE: To evaluate the outcome of Ponseti treatment carried out by the Postgraduate Orthopaedic Trainees compared with the treatment given by their Mentors. METHODS: The prospective comparative case series study was conducted at Jinnah Postgraduate Medical Centre, Karachi, and comprised idiopathic Congenital Clubfoot Deformity patients treated from September 2012 to December 2013. Also included were a few cases treated between September 2006 and September 2012, who had complete record, serial photograph and updated follow-up. The patients were divided into two groups. Those treated by residents formed Group A and those by consultants were in Group B. The follow-up duration ranged from 06 months to 05 years. Outcome measures included the number of casts required to achieve correction with Pirani score 0.5, the rate of Per-Cutaneous Achilles Tenotomy (PCAT), the rate of early relapse and treatment and failure to maintain correction. SPSS 13 was used for statistical analysis. RESULTS: Of the 172 patients in the study, 111(64.5%) patients with 185 feet were treated by the residents, while 61(35.5%) patients with 96 feet were treated by consultant. The overall mean age was 25.8±32.88 weeks (range: 1-156 weeks). The difference in age between the two groups was significant (p=0.01). A total of 166(96.51%) patients were on maintenance phase in Foot Abduction Bracing and 6(3.48%) completed the treatment successfully without residual deformity. The median number of cast per patient given by Group A was 6 and 5 in Group B. The number of 8+ casts given in Group A were 46 (24.86%) and 17 (17.7%) in Group B. Tenotomies performed in Group A were 106 (57.27%) and 70 (73%) in Group B, and overall PCAT performed were 183 (65.12%). The overall success rate was nearly similar between the two groups, with the difference of<1%. CONCLUSIONS: The best practice to achieve excellent to good results from the beginners in Ponseti technique is to provide mentorship training for the skill of Ponseti manipulation, application of cast and continued treatment.
