Complications, Pain Control, and Patient Recovery After Local Versus General Anesthesia for Open Inguinal Hernia Repair in Adults—Systematic Review and Meta-analysis

The purpose of this systematic review is to provide an ‘‘up-to-date’’ evidence-based guideline and clarify the possible benefits as well as drawbacks of local anesthesia (LA) and general anesthesia (GA) in open inguinal hernia surgery in adults. Study method comprised randomized controlled trials. Primary outcome measures were complications, pain control, and patient recovery. Secondary outcome measures were patient satisfaction and hernia recurrence. A total of 14 randomized controlled trials contributed to the study. A total of 1677 patients were analyzed, with 953 in the LA group and 724 in the GA group. Complications were statistically less frequent in the LA group compared with the GA group [odds ratio (OR), 0.31; 95% confidence interval (95% CI), 0.15, 0.64). Supplemental intraoperative analgesia had a statistical significance in the LA group, with an OR of 28.93 (95% CI, 7.86, 106.47). Postoperative pain was statistically significantly lower in the LA group [standardized eman difference (SMD), -1.06; 95% CI, -1.64, -0.48)]. Length of stay was shorter for patients who underwent operation under LA compared with those receiving GA (OR, -1.21; 95% CI, -2.08, -0.33]). Time to full mobility was shorter in the LA group, without statistical significance (OR, 3.04; 95% CI, 0.19, 47.90), whereas measuring in SMD showed significance in comparison with GA (SMD, -1.74; 95% CI, -2.34, -1.14). Hernia recurrence was not noted. Patient satisfaction was greater in the LA group (SMD, 0.65; 95% CI, 0.15, 1.15). Compared with GA, LA showed superiority in terms of complications, postoperative pain, length of stay, time to full mobility, and patient satisfaction. Therefore, it appears to be a more appropriate anesthetic technique for open inguinal hernia repair in adults

Awareness, Attitudes, and Perceptions of Croatian-Based Orthopedic and Trauma Surgeons toward Scientific Manuscripts, Publishing Internationally and Medical Writing. Results of an Online Questionnaire

The objective of this survey was to identify the importance placed by Croatian-based surgeons on writing scientific manuscripts and publishing them internationally, as well as their awareness of and attitudes toward medical writing. A link to an online survey was sent to 327 Croatian-based orthopedic and trauma surgeons. The electronic questionnaire consisted of rating scales, multiple choice questions and free text reply boxes. A total of 61 surgeons based in Croatia replied to the survey, yielding a response rate of 19% (61/327). The survey results indicate that surgeons in Croatia are active in both research and the writing of manuscripts. There is also a high level of interest among them to publish internationally in English to further their careers. While 68% (38/56) of respondents initially claimed to know about medical writing, further questioning on the subject revealed a reduced level of familiarity with the concept. Only 19% (11/58) of respondents had ever engaged the services of a medical writer and they were generally satisfied with the work done across the three areas of language, editing and scientific knowledge. Medical writers are advised to increase awareness of their services among Croatian-based orthopedic and trauma surgeons who may well have a need for their expertise

Mangled Extremity – Case Report, Literature Review and Borderline Cases Guidelines Proposal

Treatment of a mangled lower extremity represents a major challenge. The decision whether to amputate or attempt reconstruction is currently based upon surgical evaluation. The aim of this paper is to propose a new approach to surgical evaluation based on scoring systems, local clinical status of the patient as well as comorbidities, mechanism of trauma and hospital resources. Available literature regarding this topic was evaluated and a case of patient with mangled extremity is presented. Based on current literature guidelines and evidence-based medicine, management for borderline cases is proposed to aid clinical decision making in these situations. We describe a 44-year old male patient who presented with mangled lower left leg. Despite a borderline Mangled Extremity Severity Score (MESS), due to the overall health status of the patient and local clinical status with preserved plantar sensitivity and satisfactory capillary perfusion, reconstruction was attempted. After 6 months of treatment, all wounds healed completely with no pain, and satisfactory motor and sensory function was achieved. In conclusion, the treatment of mangled extremity treatment should be based on evidence based literature along with a clinical evaluation of every individual patient. Scores are helpful, but should not be taken as the sole indication for amputation

Screw placement in two different implants for proximal humeral fractures regarding regional differences in bone mineral density: An anatomical study.

BACKGROUND: The aim of this study was to investigate proximal humerus plating regarding drill depth and over penetration of the glenohumeral joint and to find a relation between these findings and different areas of bone mineral density (BMD) in the humeral head. MATERIAL & METHODS: The study sample involved 45 upper extremities from human adult cadavers. Two different plates (HOFER; PHILOS) were applied to the proximal humerus. Each hole was drilled until the respective participant thought to have placed the drill bit subchondral. Next, penetration of the far cortex was conducted to determine the residual bone stock. Additionally, the point of screw penetration of the far cortex was identified for each hole of the plates and allocated to five regions with different bone mineral density as described by Tingart et al. RESULTS: The screw penetration rate and the residual bone stock were compared within the 5 BMD regions. A significantly thicker residual bone stock was found at the central region (SD ± 13.1 mm) than in the anterior region (SD ± 9.5 mm) and in the posterior region (SD ± 8.5 mm). The anterior region revealed a significantly higher penetration rate than the posterior region (p = 0.01) and the central region (p = 0.03). CONCLUSION: The anterior region of the humeral head was associated with a higher over penetration rate of the far cortex into the glenohumeral joint and a decreased bone stock after subchondral drilling representing a reduced bone mineral density (BMD).

Evaluation of screw placement in proximal humerus fractures regarding drilling manoeuvre and surgeon's experience.

INTRODUCTION: Following proximal humeral plate osteosynthesis, mechanical complication rates ranging up to 40% have been reported. The study aims to determine the influence of surgeons' experience and the technique of drilling on the complication rate. MATERIALS AND METHODS: The sample involved 45 cadaveric humeri. Six orthopaedic surgeons were divided into two groups with regard to their level of experience (novice versus expert group). On each humerus two different proximal humerus plates were applied. Drillings were performed either with a sharp or worn drill bit (to simulate either sharp or blunt drilling). The respective holes were drilled until the respective participant thought to have placed the drill bit subchondrally, followed by perforation of the cartilage of the humeral head. Both these values and cases of unintended penetration of the articular cavity were evaluated. RESULTS: Fourteen holes (3.6%) were primary penetrated in the joint cavity in the worn-drill-bit-subgroup and 19 holes (5%) in the sharp-drill-bit-group. The latter had an average distance between the chosen subchondral position and the humeral articular surface of 8.3 mm and the worn-drill-bit-subgroup was at 10.6 mm. In the novice group 20 perforations (5.2%) of the joint space occurred and the mean interval between the chosen subchondral point and the humeral articular surface was 4.0 mm. The experienced surgeons showed a perforation rate of 3.4% and were at a mean of 14.9 mm. There were no significant differences regarding drilling manoeuvres and experience. CONCLUSION: Although our results are satisfactory, they can be traced back to the relatively high interval between the respective chosen position of the drill bit and the humeral articular surface which may not guarantee screw stability during ORIF of all fracture patterns.status: Published onlin

An anatomical study of transpedicular vs. extrapedicular approach for kyphoplasty and vertebroplasty in the thoracic spine

Introduction: Percutaneous vertebral augmentation is a common therapeutic approach for osteoporotic or osteolytic vertebral fractures. Due to the variable pedicle anatomy two different approaches, the transpedicular and the extrapedicular approach have been established. In particular, in the middle and upper thoracic spine, percutaneous procedures are challenging because of difficult visualisation of anatomical landmarks and a more unfavourable anatomy with smaller and differently orientated pedicles. Material and methods: In our cadaveric study we compared the transpedicular and the extrapedicular approach to the thoracic spine. In 26 cadaveric spine specimes, embalmed using Thiel's method, we placed a total of 486 trans- and extrapedicular K-wires through Jamshidi needles in the vertebral bodies T4 - T12 under fluoroscopy. A CT scan was then performed to verify the actual position of the K-wire. Malpositioning was defined as deviation from the planned approach or placement of the K-wire in the spinal canal or outside the vertebral body. Number and direction of malpositionings was recorded. Results: Malpositioning occurred in 68 of 468 K-wires. It was more frequent in the transpedicular (54) than in the extrapedicular (14) approach. Intraspinal malposition was seen more often in the transpedicular approach (n=36) especially in the upper and middle thoracic spine. Conclusion: In summary both approaches are relatively safe but in the upper and middle thoracic spine the risk of intraspinal malpositioning seems to be lower when using the extrapedicular approach.

Stable Gastric Pentadecapeptide BPC 157 and Striated, Smooth, and Heart Muscle

First, we review the definitively severed myotendinous junction and recovery by the cytoprotective stable gastric pentadecapeptide BPC 157 therapy, its healing that might combine both transected and detached tendon and transected muscle, ligament and bone injuries, applied alone, as native peptide therapy, effective in rat injury, given intraperitoneally or in drinking water or topically, at the site of injury. As a follow up, we reviewed that with the BPC 157 therapy, its cytoprotective ability to organize simultaneous healing of different tissues of and full recovery of the myotendinous junction might represent the particular muscle therapy against distinctive etiopathology muscle disabilities and weakness. In this, BPC 157 therapy might recover many of muscle disabilities (i.e., succinylcholine, vascular occlusion, spinal cord compression, stroke, traumatic brain injury, severe electrolyte disturbances, neurotoxins, neuroleptics, alcohol, serotonin syndrome and NO-system blockade and tumor-cachexia). These might provide practical realization of the multimodal muscle-axis impact able to react depending on the condition and the given agent(s) and the symptoms distinctively related to the prime injurious cause symptoms in the wide healing concept, the concept of cytoprotection, in particular. Further, the BPC 157 therapy might be the recovery for the disabled heart functioning, and disabled smooth muscle functioning (various sphincters function recovery). Finally, BPC 157, native and stable in human gastric juice, might be a prototype of anti-ulcer cytoprotective peptide for the muscle therapy with high curing potential (very safe profile (lethal dose not achieved), with suited wide effective range (µg-ng regimens) and ways of application)

Stable Gastric Pentadecapeptide BPC 157 and Wound Healing

Significance: The antiulcer peptide, stable gastric pentadecapeptide BPC 157 (previously employed in ulcerative colitis and multiple sclerosis trials, no reported toxicity (LD1 not achieved)), is reviewed, focusing on the particular skin wound therapy, incisional/excisional wound, deep burns, diabetic ulcers, and alkali burns, which may be generalized to the other tissues healing. ------ Recent Advances: BPC 157 has practical applicability (given alone, with the same dose range, and same equipotent routes of application, regardless the injury tested). ------ Critical Issues: By simultaneously curing cutaneous and other tissue wounds (colocutaneous, gastrocutaneous, esophagocutaneous, duodenocutaneous, vesicovaginal, and rectovaginal) in rats, the potency of BPC 157 is evident. Healing of the wounds is accomplished by resolution of vessel constriction, the primary platelet plug, the fibrin mesh which acts to stabilize the platelet plug, and resolution of the clot. Thereby, BPC 157 is effective in wound healing much like it is effective in counteracting bleeding disorders, produced by amputation, and/or anticoagulants application. Likewise, BPC 157 may prevent and/or attenuate or eliminate, thus, counteract both arterial and venous thrombosis. Then, confronted with obstructed vessels, there is circumvention of the occlusion, which may be the particular action of BPC 157 in ischemia/reperfusion. ------ Future Directions: BPC 157 rapidly increases various genes expression in rat excision skin wound. This would define the healing in the other tissues, that is, gastrointestinal tract, tendon, ligament, muscle, bone, nerve, spinal cord, cornea (maintained transparency), and blood vessels, seen with BPC 157 therapy
