A Comparison of Mini Open Transverse Incision and Longitudinal Incision for the Release of Moderate and Severe Carpal Tunnel Syndrome.

OBJECTIVES: Carpal tunnel syndrome is a common condition seen in daily clinical practice. Multiple minimally invasive techniques have emerged in the last decades for median nerve decompression. However, many research are needed to study the outcome on the patients and their safety profile. METHODS: We will compare group A that includes patients operated on using the minimally invasive transverse incision (number of patients = n = 221, females 76.7% and males 22.8%) versus group B that includes patients operated on using the longitudinal incision (n = 194, female 70.1% and male 29.9%) in term of clinical satisfaction and safety. The mean age of group A is 58.1±5.1 and that of group B is 58.8±4.8. The male and female distribution in both groups and the mean age were both similar with no statistically significant difference for the age (p = 0.79) or the gender distribution (p = 0.1). Data collected prospectively at regular intervals in time (preoperatively and at one month, three months, and six months post-carpal tunnel release (CTR)) between January 2006 and December 2021 were reviewed retrospectively. Patients' clinical findings, grip strength measurement using a hand dynamometer, and postoperative satisfaction measured using the BCTQ (Boston Carpal Tunnel Syndrome Questionnaire) scoring system were recorded and analyzed for each technique. RESULTS: A total of 415 patients were included in our study. All patients included had moderate to severe median nerve compression documented by nerve-conducted studies with positive Tinel's and Phalen's signs. Baseline demographics between group A (CTR through a longitudinal palmar mini-incision) and group B (CTR with a mini-transverse incision at the palmar crease) didn't show a statistically significant difference. Both groups showed improved grip strength and BCTQ scores at the post-operative follow-up. CONCLUSIONS: Median nerve decompression using both types of incisions has resulted in the same functional outcomes and patient satisfaction.

Evaluation and Treatment of Lumbar Spine Extradural Cysts: A Narrative Review.

The main objective was to describe the different types and characteristics of lumbar spine extradural cysts and their optimal treatment options with a focus on endoscopic technique. We searched Pubmed, EMBASE, Medline, and Google Scholar for articles published between 1967 and 2020 using the keywords "Spinal Cyst," "Extradural Cyst," and "Lumbar Cyst." The various anatomical and histological types of the extradural cysts with their presentations, etiologies, imaging, and optimal treatment with a focus on endoscopic techniques were reviewed from the articles. Lumbar spinal cysts are relatively rare pathologies that might cause radicular symptoms similar to lumbar disc herniation. Spinal extradural cysts are classified either histologically based on the cyst lining tissues (synovial cysts or non-synovial, ganglion cysts) or anatomically based on the structure of origin (epidural cysts, ligamentum flavum cysts, discal cysts, post-discectomy pseudocysts, posterior longitudinal ligament cysts, facet cysts). Surgical excision is the recommended treatment of symptomatic cysts with endoscopic techniques being a viable option. Extradural lumbar cysts can be identified based on their histological structure or depending on their structure of origin. Regardless of their classification, they could all give similar clinical findings, and the optimal treatment would be surgical excision with endoscopic technique being a viable option with a satisfactory outcome.

Joint-preserving surgery for idiopathic bilateral osteonecrosis of the distal tibia: A case report.

Introduction: Osteonecrosis (ON) is a serious pathological condition that can affect weight-bearing areas of the lower limbs, including the distal tibia. Although trauma is a common cause of ON, the condition has multiple possible etiologies. ON has been associated with a range of factors, including trauma, medication use, alcoholism, and vascular disease. Interruption of blood flow to a particular bone region is the first step in the pathophysiology of ON. Conservative management is typically indicated in the early stages of ON, but joint-preserving procedures may be necessary in cases where conservative treatment fails. Case Report: This article presents a case of bilateral ON of the distal tibia in a 38-year-old female patient without a history of trauma or identifiable risk factors. The patient was initially managed conservatively but ultimately underwent joint-preserving surgery due to treatment failure. Conclusion: Joint-preserving procedures should be considered in cases of early-stage distal tibia ON that do not respond to conservative management to prevent joint collapse. This case highlights the importance of considering ON as a possible diagnosis even in the absence of identifiable risk factors or trauma.

Ipsilateral Simultaneous Low-Energy Multiple Upper Limb Fractures in an Elderly Patient: Case Report and Review of the Literature.

Traumatic injuries of the upper limb can result in variant fracture combination. This article discusses a rare injury combination including ipsilateral proximal and distal humerus fractures alongside a distal radius fracture. The mechanism of the fall is unknown, but the patient being old with such a complex injury, one can only assume that osteoporosis played a major role. Open reduction and internal fixation was opted for the distal humerus and radius fractures, and percutaneous pinning was done for the proximal humerus fracture. Surgery is an option to each one of these injuries with different techniques available for managing such an association, with emphasis made on osteoporosis workup to help prevent such complex injuries.

Nerve transfers in the upper extremity: A review.

Injury of the brachial plexus and peripheral nerve often result in significant upper extremity dysfunction and disability. Nerve transfers are replacing other techniques as the gold standard for brachial plexus and other proximal peripheral nerve injuries. These transfers require an intimate knowledge of nerve topography, a technically demanding Intraneural dissection and require extensive physical therapy for retraining. In this review, we present a summary of the most widely accepted nerve transfers in the upper extremity described in the current literature.

Risk estimates for hip fracture from clinical and densitometric variables and impact of database selection in Lebanese subjects.

Bone mineral density (BMD) and fracture incidence vary greatly worldwide. The data, if any, on clinical and densitometric characteristics of patients with hip fractures from the Middle East are scarce. The objective of the study was to define risk estimates from clinical and densitometric variables and the impact of database selection on such estimates. Clinical and densitometric information were obtained in 60 hip fracture patients and 90 controls. Hip fracture subjects were 74 yr (9.4) old, were significantly taller, lighter, and more likely to be taking anxiolytics and sleeping pills than controls. National Health and Nutrition Examination Survey (NHANES) database selection resulted in a higher sensitivity and almost equal specificity in identifying patients with a hip fracture compared with the Lebanese database. The odds ratio (OR) and its confidence interval (CI) for hip fracture per standard deviation (SD) decrease in total hip BMD was 2.1 (1.45-3.05) with the NHANES database, and 2.11 (1.36-2.37) when adjusted for age and body mass index (BMI). Risk estimates were higher in male compared with female subjects. In Lebanese subjects, BMD- and BMI-derived hip fracture risk estimates are comparable to western standards. The study validates the universal use of the NHANES database, and the applicability of BMD- and BMI-derived risk fracture estimates in the World Health Organization (WHO) global fracture risk model, to the Lebanese.

Rectus abdominis free tissue transfer in lower extremity reconstruction: Long term follow up in 58 cases.

This study evaluates the long-term results of rectus abdominis free-tissue transfer performed for lower extremity reconstruction. METHODS: Over a period of 8 years 58 were available for long term follow-up. Indications for reconstruction included acute wounds with soft tissue defects, diabetic foot ulcers, and chronic osteomyelitis. RESULTS: At a mean follow-up of 18 years, there were no major complications in the soft tissue defect coverage group except for one patient who continued to have recurrent folliculitis over the weight bearing heel area, which was treated by repeated debridement. Among the diabetic patients, two patients had recurrent ulcerations of the forefoot which were detected early and treated conservatively. In the osteomyelitis group, however, there were no recurrences of the foot infection. CONCLUSIONS: The rectus abdominis free-tissue transfer provided an excellent method of soft tissue reconstruction with a very minimal long-term complication rate, and a very high rate of success in the treatment of diabetic foot ulcers and chronic osteomyelitis.

A Case Report of Meningeal Hemangiopericytoma: A 9-Year Journey from the Brain to the Spine.

BACKGROUND: Hemangiopericytomas (HPCs) are rare and aggressive vascular mesenchymal tumors. Unlike meningiomas, which have a similar radiologic appearance, these tumors have a higher risk of local recurrence after resection, and distant metastasis can reach up to 23%. Metastases to the vertebral bones from an intracranial HPC are very rare, with so far only 9 cases reported in the literature. CASE DESCRIPTION: We present the case of a 46-year-old man who was surgically treated for a presumed left parieto-occipital falx meningioma in 2008. He presented 9 years later with a thoracic vertebral mass that was causing relentless pain. Reexamination of the cranial pathology allowed correction of the diagnosis performed in 2008 to a meningeal HPC, and the spinal lesion was confirmed after surgery to be a metastatic tumor. CONCLUSIONS: The literature lacks randomized controlled trials and large studies defining the natural history of HPC to draw clear recommendations for a precise management of the disease. However, en bloc resection followed by radiation therapy seems to provide the optimal treatment for a long disease-free survival.

Functional outcome in adult patients following Bernese periacetabular osteotomy.

This study evaluated functional outcome following Bernese periacetabular osteotomy. In 24 patients with mean follow-up of 3.5 years, mean dysfunction score was 15.23 on the Short Musculoskeletal Function Assessment. Eighteen patients (75%) scored = or <20, indicating a high functional level. Irrespective of preoperative Shenton line continuity, most patients demonstrated a high functional level. However, a trend toward a poorer outcome was observed in patients with preoperative noncongruent joints and Tonnis osteoarthritis grade 3. These results suggest patients with less than optimal presentation may still benefit from this surgery, delaying or eliminating the need for total hip arthroplasty.

Use of pelvic incidence as a guide to reduction of H-type spino-pelvic dissociation injuries.

OBJECTIVE: Describe the use of a radiographic parameter (pelvic incidence) to assess the sagittal plane reduction of H-type sacral fractures associated with spinopelvic dissociation, and assess the relationship between standing lumbar lordosis to pelvic incidence after spinopelvic dissociation. DESIGN: Retrospective radiographic and clinical review of treatment outcomes for patients with spinopelvic dissociation injuries secondary to H-type sacral fractures. SETTING: Level I Trauma Center. INTERVENTION: Pelvic incidence (PI), a radiographic parameter that measures the orientation of the lumbar spine relative to the pelvis, has been shown to have a correlation with the adequacy of surgical reduction as well as the risk of progression of high-grade spondylolisthesis. We used this parameter as a measure of sagittal plane reduction of spinopelvic dissociation injuries. PATIENTS/PARTICIPANTS: The clinical records and radiographs of five patients with spinopelvic dissociation injuries were reviewed. MAIN OUTCOME MEASUREMENTS: Radiographic measurements included standing PI and lumbar lordosis (LL). The relationship of lumbar lordosis on pelvic incidence was tested by a regression analysis. Clinical outcome was assessed by the self-reported ability of the patient to comfortably maintain an upright stance. RESULTS: The average follow-up period was 32 (range: 12-53) months. The average final PI was 82 (60-115) degrees. The average final lumbar lordosis was 58.2 (42-77) degrees. LL was found to be significantly related to PI (P<0.05). One patient with an abnormally high PI had lumbar fatigue with persistent stance. CONCLUSIONS: Pelvic incidence is a potentially useful radiographic parameter that can be used to assess the adequacy of sagittal plane reduction in patients with spinopelvic dissociation injuries.

Acute paraplegia secondary to thoracic disc herniation of the adjacent segment following thoracolumbar fusion and instrumentation.

Proximal junctional disease is a well-recognized postoperative phenomenon in adults who are undergoing long thoracolumbar fusion and instrumentation, and is attributed to increased a junctional stress concentration. In general, the onset of symptoms in these patients is insidious and the disease progresses slowly. We report on a contrary case of rapidly progressing paraplegia secondary to acute disc herniation at the proximal adjacent segment after long posterior thoracolumbar fusion with cement augmentation at the upper instrumented vertebra and the supra-adjacent vertebra. The patient was treated with a discectomy through the costo-transverse approach combined with extension of the posterior instrumentation. The patient's neurological status improved markedly. Stress concentration at the proximal junction disc space may have caused accelerated disc degeneration which in turn lead to this complication.

Thoracic adolescent idiopathic scoliosis: selection of fusion level.

Selection of the appropriate fusion levels in thoracic adolescent idiopathic scoliosis has been traditionally a subject of debate among surgeons. Landmarks that have been suggested include the end vertebra, stable vertebra and neutral vertebra. Various results have been reported with multiple theories proposed to explain them. The clinical appearance of the patient, the type of the curve and its flexibility, the surgical technique and the instrumentation used all seem to play major roles in selecting the appropriate levels of fusion.

Evaluation of an algorithmic approach to pediatric back pain.

Pediatric patients require a systematic approach to treating back pain that minimizes the number of diagnostic studies without missing specific diagnoses. This study reviews an algorithm for the evaluation of pediatric back pain and assesses critical factors in the history and physical examination that are predictive of specific diagnoses. Eighty-seven pediatric patients with thoracic and/or lumbar back pain were treated utilizing after this algorithm. If initial plain radiographs were positive, patients were considered to have a specific diagnosis. If negative, patients with constant pain, night pain, radicular pain, and/or an abnormal neurological examination obtained a follow-up magnetic resonance imaging. Patients with negative radiographs and intermittent pain were diagnosed with nonspecific back pain. Twenty-one (24%) of 87 patients had positive radiographs and were treated for their specific diagnoses. Nineteen (29%) of 66 patients with negative radiographs had constant pain, night pain, radicular pain, and/or an abnormal neurological examination. Ten of these 19 patients had a specific diagnosis determined by magnetic resonance imaging. Therefore, 31 (36%) of 87 patients had a specific diagnosis. Back pain of other 56 patients was of a nonspecific nature. No specific diagnoses were missed at latest follow-up. Specificity for determining a specific diagnosis was very high for radicular pain (100%), abnormal neurological examination (100%), and night pain (95%). Radicular pain and an abnormal neurological examination also had high positive predictive value (100%). Lumbar pain was the most sensitive (67%) and had the highest negative predictive value (75%). This algorithm seems to be an effective tool for diagnosing pediatric back pain, and this should help to reduce costs and patient/family anxiety and to avoid unnecessary radiation exposure.
