Introduction. We hereby present results of controlled randomized trial of use of popliteal block for pain relief in ankle and hind foot surgery. Materials and methods. We have studied 63 patients over period of 9 months. Patients who needed ankle or hind foot procedure were selected for trial. Patients were explained about the trial and popliteal block along with leaflets at preoperative clinics. Patients were randomized on the day of surgery. A sealed envelop stating whether patient will go to block group (A) or no block group (B) was opened in the anaesthetic room before the patient was anaesthetized. Patients were evaluated for subjective pain scores at 30 min, 6 hrs, 12 hrs and 24 hrs after surgery. Amount of anaelgesic required and time to first dose was documented. Popliteal blocks were given by one foot and ankle consultant and one trained fellow. The block was administered in lateral position at 0.8 mA stimulus to detect the nerve. The data was compared statistically between group A and B. Results. The average pain scores in Group A (33 pts) were 0.72, 1.60, 1.51 and 1.03 at 30 min, 6 hrs, 12 hrs and 24 hrs respectively. While in Group B (30 pts) it was 2.73, 5.5, 6.03 and 3.33 at 30 min, 6 hrs, 12 hrs and 24 hrs respectively. There was statistically significant difference in pain scores at 6 and 12 hrs. There was no statistically significant difference in pain scores at 30 min and 24 hrs. Time to the request for first analgesic was statistically longer in Group A. Conclusion. Popliteal block offers an effective way of pain relief in ankle and hind foot surgery. We believe that it may reduce amount of anaesthetic or anaelgesic drug requirement as well

Juvenile idiopathic arthritis(JIA) is chronic inflammation commonly occurs in early childhood. Recently, biological therapies are used in JIA at the early stage as same as rheumatoid arthritis, due to retain joint cartilage. However, some of young patients have painful knee problems requiring knee replacement. We experienced 4 cases of JIA treated by knee arthroplasty. The average age at surgery was 33.5 years (range, 26–38 years) with a mean follow-up of 9.5 years (range, 5–18 years). We evaluated the knee range of motion and functional outcomes by the Knee Society Score (KSS), implant selection, postoperative complication, surgery of another joint. Mean range of motion improved from 76.3° (0°–120°) at pre-operation to 110.6° (80°–130°) at post-operation (P<0.05). Mean KSS increased from 47.3 ±20.1 preoperatively to 86.9 ±11.1 (P<0.01) at last follow-up and the mean KSS function from 27.5 ±25.9 to 62.5±20.2 at last follow-up (P<0.05). All of the TKAs were cemented, 5 were cruciate-retaining implant designs, whereas 2 TKAs had constrained posterior stabilized implant designs. Patellar resurfacing was undergone in all knees. Bone graft required in 1 knee within severe knee deformity. Complication were occurred in 5 knees. Medial instability in 2 knees. Skin necrosis, MCL avulsion, recurrence of the synovitis are one in each. All cases had polyarticular type. Previous THA had undergone in 5 hips, synovectomy in 3 knees, foot surgery in 2 feet. At latest follow-up, 1 of 8 TKAs (12.5%) had been revised, and had revision of its polyethylene exchange only. Patients with JIA often have valgus alignment with a flexion contracture and poor bone quality is also frequently compromised. Prescribed immunosuppressive medication or biological agents may cause to infection. In our series there were no infection, but some of these need much more soft tissue release because of severe deformity and flexion contracture. TKA survivorship for JIA is inferior to that typically seen in younger patients with osteoarthritis or rheumatoid arthritis. The knee of conservative therapy were often caused to severe functional limitations. Timimg of TKA may be indicated no matter how young the patient is. Extending timing of TKA may leads to worse outcome and postoperative function. But it may be caution that the surgical exposure can be difficult, because of stiffness, flexion contracture, bony deformity, osteopenia

Introduction: In recent years the implementation of sonication in the diagnosis of orthopaedic implant infections has improved the detection of subclinical infections. With the use of sonication of removed orthopaedic material we can detect the presence of biofilm. The method has already shown encouraging results, especially in cases of preoperative antibiotic therapy. Aim: The aim of the study was to detect infections of orthopaedic material using both sonication and standard diagnostic methods, and to compare the obtained results of both methods. For the purpose of the study we sonicated all explanted material at revision surgery and cultured the obtained samples. During revision surgery soft tissue biopsies were collected and analyzed using standard microbiologic methods. The results were compared, analyzed and additional therapy was applied, if an infection of the material was proven. During the period from September 2009 to the end of March 2014 we studied 249 cases (198 patients) of revision surgery (166 cases of revision hip arthroplasty, 53 cases of revision knee arthroplasty, 13 cases of revision foot surgery, 17 cases of revision spine surgery). Of studied cases infection was proven in 20 (8,0%) cases by soft tissue biopsies only, 90 cases (36,1%) were diagnosed both by soft tissue biopsies and sonication, 45 cases (18,1%) were diagnosed only by sonication of explanted prosthetic material and in 94 cases (37,8%) all results were negative. The statistical analysis has shown statistically significant (p<0,05) improvement of infection detection using sonication. According to our experience the implementation of sonication has shown an improvement in the diagnosis of orthopaedic implant infections. Despite certain limitations, sonication should be considered in doubtful cases of revision surgery. The use of sonication should be emphasized in cases of preoperative antibiotic treatment

Open cheilectomy is an established surgical treatment for hallux rigidus. Cheilectomy is now being performed using minimally invasive(MIS) techniques. In this prospective study we report the outcome of minimally invasive cheilectomy comparing the results with a matched group who had cheilectomy using standard open procedure. Prospective study of 47 patients. 22 patients had MIS cheilectomy between March 2009 and September 2010. We compared the outcome with a matched group (25 patients) who had open cheilectomy. Functional outcome was assessed using the Manchester Oxford Foot and ankle questionnaire (MOXFQ). The MOXFQ is a validated 16-item, patient-generated questionnaire designed to be self-completed and used as an outcome measure for foot surgery. It comprises three domains foot pain, walking and standing problems and social interaction. Total score ranges from 0 (best score) to 64 (worst score). Patients completed preoperative and postoperative questionnaires. Patients’ satisfaction and complications were recorded. In the MIS group, the median follow up was 11 months (4–23. The median preoperative MOXFQ score was 34/64(23) and the median postoperative score was 19/64 (p value <0.02) In the open group the median follow up was 17 months (9–27). The median preoperative MOXFQ score was 35/64 and the median postoperative score was 7.5/64 and this difference was statistically significant (<0.0001). There were three failures in the open group (Fusion) compared to none in the MIS. MIS cheilectomy is an effective alternative procedure with satisfactory functional outcome and high patient satisfaction. Results are comparable to the standard open cheilectomy with a lower apparent failure rate. The results of our randomised controlled trial comparing MIS cheilectomy to open cheilectomy are awaited

Introduction. Minimally Invasive foot surgery remains controversial. Potential benefits include a reduced incidence of wound complications, faster return to employment and normal footwear. There are no studies published regarding the results of minimally invasive dorsal cheilectomy. Patients and Methods. Thirty eight patients with painful grade I hallux rigidus underwent dorsal cheilectomy between April 2006 and June 2010. Minimally invasive cheilectomy (MIC) was introduced in August 2009. AOFAS scores, satisfaction, return to normal shoes and employment were assessed. Results. Twenty two patients had open cheilectomy (OC) whilst 16 had MIC. Mean follow-up was 6 months for the MIC group and 35 months for the OC group. Mean AOFAS score was 75/100 (SD 17) in the MIC group and 70/100 (SD 18). Patients rated their satisfaction as 9.1/10 for MIC and 8.6/10 for OC. There was no significant difference in time to return to normal shoes (P = 0.32) or employment (P = 0.07). Two patients (one MIS, one OC) had a superficial wound infection which resolved with oral antibiotics. One patient had a first metatarsophalangeal joint fusion in the MIS group. Two patients in the OC group went on to have a first metatarsophalangeal joint fusion and one underwent joint resurfacing. Discussion. These results suggest MIC has comparable early results to OC. Larger studies are required to further establish the benefits of MIC. Conclusion. Minimally invasive dorsal cheilectomy seems to offer a safe alternative to open cheilectomy with promising early results. Patient satisfaction with this procedure is very high

In orthopaedic surgery, as in many other surgical fields, there is a clear tendency towards the use of minimally invasive procedures. These techniques are increasingly being implemented almost routinely for procedures such as spine and pelvis surgery. However, for fracture treatment and for applications involving small bones, such as hand and foot surgery, these systems are hardly ever used. We introduce a new system for image based guidance in traumatology. We included 20 patients with a fracture of the fifth metatarsal. They were randomised on admission into two groups. Ten patients in the metatarsal group were operated conventionally and ten were operated with the assistance of a new image guidance system. This system is based on 2D-fluoro images which are acquired with a conventional c-arm and are transferred to the system workstation. After detecting marked tools, it can be used to display trajectories for K-wire guidance in the c-arm shot. The average duration of surgery (time from incision to suture) in the image-based group was 12.7 minutes ± 5.5 (min. 6, max. 23), in the conventional group it was 17 minutes ± 6.5 (min. 7, max. 28) (p=0.086). The average duration of radiation was 18 seconds ± 8.5 (min. 6, max 36) in the image-based group vs. 32.4 seconds ± 19.4 (min. 12, max. 66) in the conventional group (p=0.057). An average of 4.7 C-arm shots ± 2 (min 2, max 9) were necessary in the image-based group to position the K-wire. For the conventional group, 8.2 shots ± 2.3 (min 4, max 12) were used (p=0.0073). It took 1.6 trials ± 0.7 (min.1, max. 3) to position the K-wire for the image-based procedures, in the conventional group 2.7 trials ± 0.9 (min. 1, max 4) were necessary (p=0.0084). There were no malfunctions or adverse events in any of the image-based navigational cases. No screws needed to be replaced in the image-based group. In the conventional group, two screws were replaced intra-operatively because they were too short in the control c-arm shot, and the screw threads did not bridge the fracture gap completely, leading to insufficient compression. In this pilot study with only a small sample size, the image-based guidance system could be integrated into the existing surgical workflow and was used for applications, where existing navigation systems are not commonly used. The technology gives the surgeon additional information and can reduce the number of trials for perfect implant positioning. This potentially increases the safety of the surgical procedure and spares intact bone substance which is essential for the footing of implants in small bones and fragment fixation. Whether these factors contribute to a reduction in complications or revision rate must be confirmed in larger prospective studies

There has been an in increase in the availability of effective biological agents for the treatment of rheumatoid arthritis as well as a shift towards early diagnosis and management of the inflammatory process. This article explores the impact this may have on the place of orthopaedic surgery in the management of patients with rheumatoid arthritis.

A total of 38 patients with leprosy and localised nerve damage (11 median at the wrist and 37 posterior tibial at the ankle) were treated by 48 freeze-thawed skeletal muscle autografts ranging between 2.5 cm and 14 cm in length. Sensory recovery was noted in 34 patients (89%) and was maintained during a mean period of follow-up of 12.6 years (4 to 14). After grafting the median nerve all patients remained free of ulcers and blisters, ten demonstrated perception of texture and eight recognised weighted pins. In the posterior tibial nerve group, 24 of 30 repairs (80%) resulted in improved healing of the ulcers and 26 (87%) demonstrated discrimination of texture. Quality of life and hand and foot questionnaires showed improvement; the activities of daily living scores improved in six of seven after operations on the hand, and in 14 of 22 after procedures on the foot. Another benefit was subjective improvement in the opposite limb, probably because of the protective effect of better function in the operated side. This study demonstrates that nerve/muscle interposition grafting in leprosy results in consistent sensory recovery and high levels of patient satisfaction. Ten of 11 patients with hand operations and 22 of 25 with procedures to the foot showed sensory recovery in at least one modality.
