The mean Lysholm score increased from 44.3 per operatively to 86.3 ( ).Tegner activity score improved from 2.8±1 pre operatively to 5.6±2 ( ). Surgical treatment of unstable OCD using autogenous osteochondral graft shows successful outcomes. In addition to reliable fixation, it can enhance healing and convert an uncontained lesion to contained one appropriate for autogenous osteochondral grafting with healthy cartilage.

Carpal tunnel syndrome (CTS) is characterized by complications such as pain, paresthesia, and numbness in the fingers. There are some surgical therapies for the management of severe carpal tunnel, but differences exist between the treatments available for creating the opposition. The current study was conducted to compare the effect of modified Camitz and BRAND techniques on thumb opposition in patients with severe CTS. A total of 40 patients with severe CTS who were candidates for opponensplasty were enrolled in this clinical trial study at Alzahra and Kashani hospitals, Isfahan, Iran, from 2014 to 2018. The patients were divided into two groups of modified Camitz and BRAND. Quick DASH-9 and Kapandji scores as well as pulp and side pinch and pronation angle were assessed before and after the surgeries. Quick DASH-9 score, Kapandji score, pulp and side pinch and pronation angle significantly improved post-operatively ( , , , , and , respectively). But, no significant differences were seen in the mentioned variables between both groups pre and post-operative ( , for all the studied variables). No postsurgical complications were seen in any of the groups. The findings of the present study demonstrated that, both Modified Camitz and BRAND techniques are effective and safe techniques, yielding high improvements, but no serious complications. Both techniques can be considered for treatment of patients with severe CTS.

The maintenance of deformity in the ankle and hindfoot after correction of knee deformity following knee arthroplasty may cause abnormal tension in the knee and patient dissatisfaction. The aim of this study was to determine the effect of knee arthroplasty on the hindfoot alignment in patients with severe genu varum and valgum. A total of 84 patients with primary osteoarthritis, were enrolled in the study. The knee deformity was measured using a long leg film before surgery. The long axial radiographic view of hindfoot was taken in the standing position for all patients, before and six months after surgery. Comparisons were made on changes in the hindfoot angles measured before and after surgery. A total of 84 patients with mean age of 62.28 ± 7.77 years, 77 (92%) and seven patients (eight percent) had knee varus and valgus deformity, respectively. In the knee varus group, the mean preoperative hindfoot angle was + 5.32 ± 6.12 ° (valgus) which was changed to - 0.25 ± 4.91 ° (varus) in the postoperative rthroplasty. The severity of knee deformity does not correlate with the severity of the hindfoot deformity before and after surgery. An oscillating bone saw is rarely used to perform laminectomy. The purpose of this study was to describe a relatively quick and harmless technique for multilevel laminectomy in patients with lumbar spinal stenosis (LSS) using an oscillating bone saw to find out how this instrument affects the time of surgery and rate of complications. This prospective study was conducted on 45 patients with LSS who required multilevel laminectomy. The bones were cut using an oscillating sagittal saw equipped with a fine 1-cm blade. Posterolateral fusion was performed if any evidence of spinal instability occurred, or the correction of deformity was addressed. The time spent for laminectomy from initial cutting to the whole bone removal (T1) and the duration of laminectomy (i.e., from initiation to the end of decompression; T2) were recorded for the corresponding level. The volume of harvested autograft was also measured, and any dural injuries were reported. Posterolateral fusion was performed on 32 (71.1%) patients. The mean T1 and T2 per level were estimated at 70.5±5.4 and 157.5±12.1 sec, respectively. In addition, the mean volume of harvested autograft per level was obtained as 3.5±1.2 cc. https://www.selleckchem.com/products/CP-690550.html No durotomy was observed during laminectomy using an oscillating bone saw. However, a dural tear occurred in one patient when a Kerisson punch was utilized for ligamentum flavum removal and foraminotomy. Based on the findings, it can be concluded that laminectomy by means of the oscillating bone saw is a safe procedure that provides a sufficient volume of harvested autograft for fusion. This technique could also induce a remarkable reduction in the time of surgery.

Acquiring knowledge about anatomic and geometric quantities of bones is among the most vital parameters in orthopedic surgery that has a significant effect on the treatment of various disorders and subsequent outcomes. The aim of this study was to obtain anthropometric information for distal femur in order to compare with similar dimensions of prosthesis used in total knee arthroplasty (TKA) surgery and to design more suitable and optimal components. Morphological data of distal femur were measured in 132 knees (81 males and 51 females) using magnetic resonance imaging (MRI). The data included anterior-posterior (AP) length, medial-lateral (ML) width, medial AP (MAP), lateral AP (LAP), MAP to LAP distance in the anterior distal femur namely anterior medial lateral (AML) width, medial and lateral condyle width, and intercondylar notch. The aspect ratio (ML/AP) was also calculated and the results were compared with similar dimensions of currently used knee implants. Our data showed that men are significantly larger in all dimensions than women.
