Multidisciplinary Approach to the Management of Extensive Dermato-fibro-sarcomas Involving the Chest Wall

Dermato-fibro-sarcomas are known for high-recurrence rates. The gold standard of management is surgical excision with clear margins. Such margins on the chest results in large defects which require complex reconstructive procedures. We report a case series of patients managed by a multidisciplinary team with good outcomes. A total of 12 patients with extensive dermato-fibro-sarcoma of the anterior chest wall were treated over a period of 5 years in our setting. The age range was 25 to 54 years. Skeletal defects were reconstructed with Prolene mesh and methyl acrylate cement in 10 of the 12 patients. Pedicle flaps were used in nine patients. All margins were clear of tumors, with the nearest margin being 1.5 cm. One patient had a recurrence. No donor-site morbidity was recorded in any of the patients.In conclusion, a multidisciplinary approach provides improved outcomes in the management of large dermato-fibro-sarcomas of the chest wall. With this approach, extensive dissection of the tumor is achieved, and reconstruction is performed with minimal complication.     

Comprehensive review of surgical approaches to the elbow

The choice of the most suitable surgical approach to the elbow forms the foundation of any successful elbow surgery. The surgical approach is based on the injury or pathology to be addressed and therefore specific anatomical details need to be considered. The surgeon must be comfortable with the bony, ligamentous and neurovascular anatomy of the elbow to consider and execute the best approach for each problem. This is an imperative to avoid iatrogenic injury.This article provides a detailed analysis, valuable technical tips, advantages and disadvantages of the most common approaches to the elbow. The lateral approaches include the Kocher, Kaplan and Extensor Digitorum Communis (EDC) Split approaches, the medial approaches include the Hotchkiss, Flexor carpi ulnaris (FCU) splitting approach, the Taylor and Scham approach. The anterior approach includes the anterior neurovascular interval approach and the posterior approaches include the Olecranon osteotomy, triceps sparing, triceps reflecting approach and finally the Boyd interval approach. The text and illustrations will provide a structured overview for the practicing surgeon.

A mini-incision carpal tunnel release technique to prevent pillar pain: A technical note

Pillar pain represents one of the most common complications of classic open carpal tunnel release (CTR). This complication causes a sense of discomfort worse than the compression syndrome itself. We, herein, introduce a new treatment method for CTR through a mini-incision, which allows subcutaneously cutting the transverse carpal ligament (TCL) and releasing the median nerve without neurovascular complications. This mini-incision approach can allow the direct visualization and preservation of the thenar motor branch in those rare cases where it has an aberrant origin. For the past 10 years, we have consecutively performed this technique in the surgical treatment of 318 patients with the diagnosis of primary CTS, without developing any neurovascular and tendon injuries as well as pillar pain.     

Comparison of extreme lateral approach with posterior approach in the treatment of lumbar degenerative diseases: A meta-analysis of clinical and imaging findings

ObjectiveTo compare clinical and imaging findings between extreme lateral lumbar interbody fusion (XLIF) and posterior fusion (PF) via meta-analysis for the treatment of lumbar degenerative diseases.MethodsEnglish papers reporting clinical and imaging findings for the treatment of lumbar degenerative diseases with XLIF and PF published electronically in the PubMed, Embase, Cochrane Library, and Web of Science databases from January 2006 to August 2019 were retrieved. Two authors independently extracted data and evaluated the quality of the included literature. Meta-analysis of outcome measures was performed using Stata 14 and RevMan 5.3 software.ResultsThis meta-analysis included 744 patients from nine studies, two of which were prospective studies, while the others were retrospective studies. The quality of each study was determined to be high. The meta-analysis showed no significant differences in the operative time, length of hospital stay, clinical effectiveness, and improvement in postoperative global sagittal alignment between two approaches (P > 0.05). However, XLIF was significantly better than PF in reducing intraoperative blood loss and recovery of local sagittal alignment (P < 0.05). Moreover, the high incidence of postoperative complications were detected in XLIF group (P < 0.05).ConclusionsBoth surgical approaches have equally promising clinical effectiveness for the treatment of lumbar degenerative diseases. Although XLIF can reduce intraoperative blood loss and obtain better postoperative local sagittal alignment than PF, the high incidence of postoperative complications should prompt us to consider why XLIF procedure is still being offered to our patients and how we can reduce these complications. In addition, any conclusions should be taken with caution because of the mix of prospective and retrospective studies, and the high heterogeneity and bias.

Analgesic Effects of Ultrasound‐Guided Iliohypogastric/Ilioinguinal Nerve Block Combined with Lateral Femoral Cutaneous Nerve Block in Total Hip Arthroplasty via Direct Anterior Approach: A Retrospective Cohort Study

ObjectiveThis study aimed to explore the efficacy and safety of the combination of lateral femoral cutaneous nerve blocks (LFCNB) and iliohypogastric/ilioinguinal nerve blocks (IHINB) on postoperative pain and functional outcomes after total hip arthroplasty (THA) via the direct anterior approach (DAA).MethodsIn this retrospective cohort study, patients undergoing THA via the DAA between January 2019 and November 2019 were stratified into two groups based on their date of admission. Sixty‐seven patients received LFCNB and IHINB along with periarticular infiltration analgesia (PIA) (nerve block group), and 75 patients received PIA alone (control group). The outcomes included postoperative morphine consumption, postoperative pain assessed using the visual analogue scale (VAS), the QoR‐15 score, and functional recovery measured as quadriceps strength, time to first straight leg rise, daily ambulation distance, and duration of hospitalization. The Oxford hip score and the UCLA activity level rating were assessed at 1 and 3 months after surgery. In addition, postoperative complications were recorded. Patients were also compared based on the type of incision used during surgery (traditional longitudinal or “bikini” incision).ResultsPatients in the nerve block group showed significantly lower postoperative morphine consumption, lower resting VAS scores within 12 h postoperatively, lower VAS scores during motion within 24 h postoperatively, and better QoR‐15 scores on postoperative day 1. These patients also showed significantly better functional recovery during hospitalization. At 1‐month and 3‐month outpatient follow up, the two groups showed no significant differences in Oxford hip score or UCLA activity level rating. There were no significant differences in the incidence of postoperative complications. Similar results were observed when patients were stratified by type of incision, except that the duration of hospitalization was similar.ConclusionCompared to PIA alone, a combination of LFCNB and IHINB along with PIA can improve early pain relief, reduce morphine consumption, and accelerate functional recovery, without increasing complications after THA via the DAA.
