Purpose: Humeral lengthening in patients with post septic shortening is a challenging procedure for Orthopaedic surgeon. The aim of this study was to evaluate the efficacy and safety of humeral lengthening using Ilizarov fixator. We reviewed the literature on humeral lengthening using different fixators with regard to indications, operative technique, results and complications. We also retrospectively reviewed 12 patients treated with humeral lengthening using Ilizarov external fixation. The etiology was epiphyseal injury (7 cases), infection (5 cases). The average age at surgery was 14,5 years (range 12,5-23,5) with post septic humeral shortening. The patients were assessed clinically and radio-graphically. Follow up ranged from 1-10-years.The magnitude of lengthening achieved ranged from 5-15cm with an average of 7, 5cm. Functionally all the patients returned to their preoperative jobs and daily activities including sports. Complications included pin track infection in 8 patients, radial nerve palsy which recovered completely in one patient. Conclusion; Humeral lengthening is a valid method that improves the outcome following arm shortening and deformity correction including angulation and rotation. Extensive lengthening up to 100% of the original length could be achieved without increasing the risk of complications.

AbstractPatient-specific instrumentation (PSI) has been introduced to simplify and make total knee arthroplasty (TKA) surgery more precise, effective, and efficient. We performed this study to determine whether the postoperative coronal alignment is related to preoperative deformity when computed tomography (CT)-based PSI is used for TKA surgery, and how the PSI approach compares with deformity correction obtained with conventional instrumentation. We analyzed pre-and post-operative full length standing hip-knee-ankle (HKA) X-rays of the lower limb in both groups using a convention > 180 degrees for valgus alignment and < 180 degrees for varus alignment. For the PSI group, the mean (± SD) pre-operative HKA angle was 172.09 degrees varus (± 6.69 degrees) with a maximum varus alignment of 21.5 degrees (HKA 158.5) and a maximum valgus alignment of 14.0 degrees. The mean post-operative HKA was 179.43 degrees varus (± 2.32 degrees) with a maximum varus alignment of seven degrees and a maximum valgus alignment of six degrees. There has been a weak correlation among the values of the pre- and postoperative HKA angle. The adjusted odds ratio (aOR) of postoperative alignment outside the range of 180 ± 3 degrees was significantly higher with a preoperative varus misalignment of 15 degrees or more (aOR: 4.18; 95% confidence interval: 1.35–12.96; p = 0.013). In the control group (conventional instrumentation), this loss of accuracy occurs with preoperative misalignment of 10 degrees. Preoperative misalignment below 15 degrees appears to present minimal influence on postoperative alignment when a CT-based PSI system is used. The CT-based PSI tends to lose accuracy with preoperative varus misalignment over 15 degrees.
