Background/Aim. Total hip arthroplasty is the replacement of the hip joint with an artificial one. Standard surgical procedures involve a long skin incision and extensive dissection of healthy tissue. Mini-incision surgery is a modification of standard operative approaches. In addition to a significantly smaller skin incision, the main difference is based on much less damage to soft tissues, especially the muscles that move the hip. The aim of this study was to compare the early results of the mini-incision and a standard approach in total hip arthroplasty and to determine the advantages and disadvantages of the mini-incision surgical technique. Methods. A retrospective study analyzed data based on 63 patients who underwent total hip arthroplasty with a mini-incision and standard approach at the Institute of Orthopaedic Surgery “Banjica”, Belgrade from 2004 to 2010. All the patients suffered from primary coxarthrosis. All operations were carried out by the same surgical team. All patients were clinically evaluated before and after the surgery using the Harris Hip Score (HHS). Results. The group of patients operated on with the mini-incision approach included 32 patients, while 31 patients made up the group of patients operated on with the standard approach. Comparing these groups did not reveal a statistically significant difference in age, body mass index, surgery duration, and HHS before the surgery. A statistically significant difference was determined by comparing intraoperative blood loss, the amount of drainage fluid after the surgery, and the HHS after the surgery. Conclusion. The mini-incision posterolateral approach, compared to the standard approach, apart from an esthetically more acceptable scar, achieves significantly less intraoperative blood loss and better hip function with almost the same risk of complications. © 2022 Inst.

Introduction: Split tendon transfer of tibialis posterior (SPOTT) is a treatment option for the hindfoot varus deformity in patients with cerebral palsy (CP). The purpose of this study was to present the long-term results of the newly modified SPOTT procedure developed by our senior author and compare it with the standard SPOTT technique in equinovarus foot deformity due to CP. Method: Our retrospective cohort study included patients with spastic foot deformity due to CP treated with the standard or modified SPOTT technique. Patients’ age at the time of the surgery was ≥ five years with follow-up period of at least four years. Surgical outcomes were evaluated using Kling’s criteria during the patient’s last follow-up visit. Results: The analysis included 124 patients (146 feet), where 105 feet were treated by the standard SPOTT technique and 41 feet by the modified SPOTT technique. Patients’ median age at the time of the surgery was 11 years. Patients were followed-up for a median period of eight years during which the modified SPOTT technique showed significantly better surgical outcomes compared with the standard group (excellent/good results in 38 feet, 92.7%, vs. 79 feet, 75.2%, p = 0.02). Two groups of patients did not significantly differ in GMFCS level, age at the time of the surgery, or patient gender. There was similar distribution in CP patterns in the standard and modified groups; spastic hemiplegia was the most prevalent form, followed by spastic diplegia and spastic paraplegia. Overall, better surgical success was achieved in patients with GMFCS levels I–III (100%, 94.8%, and 69.8%, respectively). SPOTT procedure failure was frequently noticed in patients with GMFCS level IV (90.9%). Conclusion: The modified SPOTT procedure demonstrated efficiency and safety in patients with equinovarus foot deformity due to CP during the long-term follow-up. Compared with the standard procedure, the newly modified SPOTT technique showed significantly better surgical outcome, irrespective of the patients’ gender, age, initial GMFCS level, and CP type. © 2019, SICOT aisbl.

Aim: This study evaluates the effects of three surgical procedures in the treatment of pronation deformities of the forearm in cerebral palsy patients; namely the transposition of pronator teres to extensor carpi radialis brevis muscle; and rerouting of the pronator teres muscle with or without pronator quadratus muscle myotomy. Methods: Sixty-one patients, 48 male/13 female, with a mean age of 17 years (5-41 years) were treated between 1971 and 2011. Pronator teres transposition was performed in 10, pronator rerouting in 35, and pronator rereouting with pronator quadratus myotomy in 16 patients. Ranges of motion, and assessments using the Quick Dash, Mayo Scoring, and Functional Classification system of upper extremity, were made before and after surgery. Mean follow-up was 17.5 years (3-41 years). Results: All three procedures led to significantly improved ranges of motion and upper limb function, with good/excellent results in 80 % of patients. Mean active supination improved from 10 ° (0-60 °) to 85 ° (30-90 °) (p < 0.001). There were significant improvements in Functional Classification system for the upper extremity scores (p < 0.003), Mean Quick Dash Scores improved from 58.41 (38.63-79.54) to 44.59 (27.27-68.18), and mean MEPS improved from 68 (30-85) to 84 (60-100) following surgery. All three techniques had statistically improved MEPS following surgery (p < 0.001); only the pronator teres muscle rerouting with pronator quadratus myotomy showed an improved Functional Classification system for the upper extremity score (p < 0.05); and only the pronator teres rerouting procedure showed an improved Quick Dash score (p < 0.05). There were no statistically significant differences in outcomes between different ages groups, and no significant differences between isolated pronator teres muscle rerouting were compared with those undergoing simultaneous treatment of carpal flexion and thumb adduction deformities (p > 0.05). Conclusion: Surgery is very effective in the management of pronation deformities of the forearm in patients with cerebral palsy. Isolated pronator teres rerouting is probably the most effective and simple technique. Adjunctive pronator quadratus myotomy does not lead to an improvement in the results and requires an additional surgical approach. There should be no age restriction to surgery, as all age groups appear to benefit from similar improvements in range of motion and upper limb function. © 2015 Čobeljić et al.
