The effect of exercise post vertebral augmentation in osteoporotic patients: A systematic review and meta-analysis.

This meta-analysis investigated the effects of exercise on Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores following vertebroplasty or kyphoplasty in osteoporotic fractures. A literature search of PubMed, EMBASE (Elsevier), CiNAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Scopus, and Web of Science was conducted from database inception to October 6, 2022. Eligible studies reported osteoporosis patients over 18 years of age with a diagnosis of at least one vertebral fracture via radiography or clinical assessment. This review was registered in PROSPERO (ID: CRD42022340791). Ten studies met the eligibility criteria (n = 889). VAS scores at baseline were 7.75 (95% CI: 7.54, 7.97, I2 = 76.11%). Following initiation of exercise, VAS scores at the endpoint of 12 months were 1.91 (95% CI: 1.53, 2.29, I2 = 92.69%). ODI scores at baseline were 68.66 (95% CI: 56.19, 81.13, I2 = 85%). Following initiation of exercise, ODI scores at the endpoint of 12 months were 21.20 (95% CI: 14.52, 27.87, I2 = 99.30). A two-arm analysis demonstrated improved VAS and ODI for the exercise group compared to non-exercise control at 6 months (MD = -0.70, 95% CI: -1.08, -0.32, I2 = 87% and MD = -6.48, 95% CI: -7.52, -5.44, I2 = 46%, respectively) and 12 months (MD = -0.88, 95% CI: -1.27, -0.49, I2 = 85% and MD = -9.62, 95% CI: -13.24, -5.99, I2 = 93%). Refracture was the only adverse event reported and occurred almost twice as frequently in the non-exercise group than in the exercise group. Exercise rehabilitation post vertebral augmentation is associated with improved pain and functionality, particularly after 6 months of exposure, and may reduce refracture rate.

A Retrospective Comparative Study of Long-Term Outcomes Following Cervical Total Disc Replacement Versus Anterior Cervical Discectomy and Fusion.

Introduction The traditional treatment for patients with radiculopathy and myelopathy caused by degenerative disc disease was anterior cervical discectomy and fusion (ACDF). However, a documented complication of ACDF is adjacent segment degeneration (ASD). An alternative that was developed was total disc replacement (TDR). The aim of this study was to determine and compare the short- and medium-to-long-term outcomes after a TDR or ACDF. Methods A retrospective review of 154 patients who had single and two-level ACDFs and 90 TDRs performed by a single surgeon between 2011 and 2017 was conducted. Parameters for comparisons include both radiological evaluation and patient-reported outcome measures (PROMS) at six weeks, one year, and two years postoperatively. The Neck Disability Index (NDI) and the visual analogue scale (VAS) for neck and arm pain are used to evaluate pain, function, patient satisfaction, and overall clinical success. Results TDR and ACDF showed significant improvement in NDI and VAS when compared to pre- and post-operatively at both six weeks (p<0.05 & P=0.032, respectively) and two years (p<0.05 & 0=0.026, respectively). TDR vs. ACDF showed no significant difference (p<0.05). VAS scores after ACDF showed improvement from 13.41 to 3.94 at two years (p<0.001). TDR showed similar scores of 12.5 to 3.55 (p<0.001). The radiological fusion rate at 12 or 24 months showed no significant difference between the two groups. There were two cases that required re-operation after ACDF (1.2%), and two that required TDR (2.2%). Conclusion Both TDR and ACDF lead to clinically significant improvements in pain and function scores. We did not find a statistically significant difference in NDI and VAS in the neck and arm. The results are in agreement with others' assessments of these two treatment modalities. Our conclusions supplement the literature about these operative options for degenerative disc disease of the cervical spine and are a useful addition to the armamentarium in the assessment of patients with degenerative pathology of the c-spine.

Complications and functional outcome following fixation of complex, intra-articular fractures of the distal radius with the AO Pi-Plate.

This study investigates the efficacy of the AO Pi-plate in the treatment of complex, intra-articular fractures of the distal radius. We retrospectively analysed the clinical and radiological results of 19 consecutive patients who underwent open reduction and internal fixation for dorsally displaced, intra-articular fractures of the distal radius using the AO Pi-plate. The final functional outcome was assessed using the Gartland & Werley scoring system. The average follow-up period was 34.3 months. Wrist movement was restored to a near normal range in all the patients. The functional outcome as measured by the Gartland & Werley scoring system showed excellent and good results in 15 (88%) of the patients. The implant was removed in 4 (23%) of the patients due to extensor tenosynovitis and restriction of flexion. This study demonstrates that although the functional outcome following fixation of complex distal radius fractures with the AO Pi-plate is good, there is a risk of developing extensor tenosynovitis and limitation of flexion. We recommend that the implant be used sparingly and if used then elective removal of the implant should be considered after fracture union.

Horner's syndrome secondary to intervertebral disc herniation at the level of T1-2.

A 54-year-old Caucasian woman presented with a 6 week history of periscapular pain and a T1 radiculopathy associated with Horner's syndrome. MRI of her cervicothoracic spine revealed an intervertebral disc herniation at the level of T1-2. During investigation she experienced some improvement in her symptoms and a conservative approach was pursued. At 6 months her pain and radiculopathy had resolved, and there was mild residual ptosis.

Orgasmic dural tear: an unusual delayed presentation of postural headache following lumbar discectomy.

A 28-year-old woman presented with a severe unremitting frontal postural headache associated with photophobia. This started immediately after standing following reaching orgasm during sexual intercourse. Fifty-two days previously, the patient underwent bilateral L4-L5 decompression laminotomies and a left L4-L5 discectomy for excision of a large herniated intervertebral disc. Subarachnoid haemorrhage was excluded with a CT scan. Brain and lumbar MRI showed enhancement of the pachymeninges and a cerebrospinal fluid (CSF) leak into the deep soft tissue planes. Conservative treatment for 5 days failed to alleviate the patient's symptoms. An exploration and repair of a dural tear was performed. Subsequently, the headache subsided but the patient developed a low-grade infection requiring 12 weeks of antibiotics. Six months later the patient was asymptomatic. This is the first case report of a delayed presentation of a dural tear occurring during sexual intercourse following lumbar surgery.

Next generation of growth-sparing techniques: preliminary clinical results of a magnetically controlled growing rod in 14 patients with early-onset scoliosis.

STUDY DESIGN: Prospective nonrandomized study. OBJECTIVE: To report the preliminary results of magnetically controlled growing rod (MCGR) technique in children with progressive early-onset scoliosis. SUMMARY OF BACKGROUND DATA: The growing rod (GR) technique is a viable alternative for treatment of early-onset scoliosis. High complication rate is attributed to frequent surgical lengthening. The safety and efficacy of MCGR were recently reported in a porcine model. METHODS: Multicenter study of clinical and radiographical data of patients who underwent MCGR surgery and at least 3 distractions. Distractions were performed in clinic without anesthesia/analgesics. T1-T12 and T1-S1 heights and the distraction distance inside the actuator were measured after lengthening. RESULTS: Fourteen patients (7 girls, 7 boys) with a mean age of 8 years, 10 months (3 yr, 6 mo to 12 yr, 7 mo) had 14 index surgical procedures. Of the 14, 5 had single-rod (SR) surgery and 9 had dual-rod (DR) surgery, with overall 68 distractions. Diagnoses were idiopathic (N = 5), neuromuscular (N = 4), congenital (N = 2), syndromic (N = 2), and neurofibromatosis (N = 1). Mean follow-up was 10 months (5.8-18.2). The Cobb angle changed from 60° to 34° after initial surgery and 31° at latest follow-up. During distraction period, T1-T12 height increased by 7.6 mm for SR (1.09 mm/mo) and 12.12 mm for DR (1.97 mm/mo). T1-S1 height gain was 9.1 mm for SR (1.27 mm/mo) and 20.3 mm for DR (3.09 mm/mo). Complications included superficial infection in 1 SR, prominent implant in 1 DR, and minimal loss of initial distraction in 3 SR after index. Partial distraction loss observed after 14 of the 68 distractions (1 DR and 13 SR) but regained in subsequent distractions. There was no neurological deficit or implant failure. CONCLUSION: Preliminary results indicated MCGR was safe and provided adequate distraction similar to standard GR. DR achieved better initial curve correction and greater spinal height during distraction compared with SR. No major complications were observed during the follow-up.

Evaluation of the modified Elmslie-Trillat procedure for patellofemoral dysfunction.

The goal of this study was to evaluate the Elmslie-Trillat procedure for recurrent patellar dislocation, patellofemoral pain (with extensor mechanism malalignment), or a combination of both. Thirty-two patients underwent the modified Elmslie-Trillat procedure, consisting of a lateral retinacular release and medialization of the tibial tuberosity for recurrent patellar dislocation, patellofemoral pain, or both. Twenty-nine of 32 patients were available for follow-up. All patients were evaluated clinically and radiologically. Subjective scores were evaluated using the Cox grading system and objective scores using Fulkerson's functional knee score. Average patient age was 33 years. Mean follow-up was 45 months. Subjectively, using the Cox grading system, 10 patients (34%) had an excellent result, 8 (28%) had a good result, 8 (28%) had a fair result, and 3 (10%) had a poor result. All patients with patella dislocation had an excellent or good subjective result, while only 3 patients (34%) with the primary symptom of patellofemoral pain with extensor mechanism malalignment and 4 patients (44%) with a combination of both symptoms had a good or excellent result. Mean Fulkerson's functional knee score was excellent for patients with dislocation only, and fair for those with only pain or both pain and dislocation. The congruence angle was corrected in all patients with this technique. There were no further dislocations in our series. Two patients required hardware removal. The Elmslie-Trillat procedure is a good surgical option for treatment of recurrent patella instability following failed conservative therapy. However, the results are not as favorable for patients with patellofemoral pain without instability.
