Purpose Methods Results Conclusion The conjoined tendon‐preserving posterior (CPP) approach is a modified posterior approach for total hip arthroplasty (THA) that preserves the short external rotator muscles and most ischiofemoral ligaments. The objective of the present study was to compare the short‐term clinical outcomes, complications, and imaging evaluations of CPP and posterior approaches in THA.This retrospective study included 83 patients from May 2018 to September 2021: 36 patients with 42 hips who underwent THA with the CPP approach (CPP group) and 47 patients with 60 hips who underwent THA with the standard posterior approach (PA group) with a minimum of 2 years of follow‐up. Assessment tools included operative times, blood loss, preoperative and last follow‐up Harris Hip Scores (HHS), postoperative complications, and implant placement angles between the groups. Statistical analysis was performed using chi‐square tests and T‐tests.The CPP approach had a significantly longer operative time and greater blood loss compared to the PA group. Preoperative and postoperative HHS were not significantly different between groups. Considering complications, the PA group had one case each of dislocation and infection, and the CPP group had two cases of sciatic nerve palsy, but the difference was not significant. Cup anteversion, inclination and stem anteversion were not significantly different between groups.Functional outcomes, complication rates, and implant placement angles were comparable with the posterior approach, and the CPP approach has the potential to reduce postoperative dislocations. However, careful attention should be paid to sciatic nerve palsy during early initiation of the CPP approach, and this study did not demonstrate that the CPP approach was clearly superior to the posterior approach.

Background/Objectives: The direct superior approach (DSA) is a tissue-sparing alternative to the traditional posterior approach (PA) in total hip arthroplasty (THA), potentially offering improved recovery and fewer complications. This study compares perioperative parameters, radiological and functional outcomes, and complications between the DSA and the PA in primary THA. Methods: A systematic review and meta-analysis were conducted following PRISMA guidelines. Databases searched included MEDLINE/PubMed, Cochrane Library, Embase, and Scopus. Studies comparing the DSA and the PA in primary THA were included based on predefined criteria. Data extraction and quality assessment were performed independently by two authors. Statistical analyses included calculating standardized mean differences (SMD), odds ratios (OR), and 95% confidence intervals (CI). Heterogeneity was assessed using the χ2 test, I2 statistics, and sensitivity analyses. Results: Out of 126 identified articles, 10 studies were included, which encompassed 28,063 patients (DSA: 1464; PA: 26,599). Significant advantages of the DSA over the PA were observed in blood loss (SMD −0.26, p < 0.01), transfusion rate (OR 0.59, p = 0.03), length of stay (SMD −0.59, p < 0.01), discharge to home rates (OR 2.32, p < 0.01), and incision length (SMD −2.75, p < 0.01). No significant differences were found in radiological outcomes or most functional scores, although the DSA showed higher Harris Hip Scores at 1 month (SMD 0.77, p < 0.01). Conclusions: The DSA offers significant perioperative advantages over the PA, including reduced blood loss, transfusion rates, LOS, incision length, and improved early functional recovery with higher discharge to home rates. Comparable complication rates and radiological outcomes support the DSA's safety and efficacy for quicker recovery in THA. [ABSTRACT FROM AUTHOR]

Objective: The craniovertebral junction (CVJ) presents intricate anatomical challenges. In severe or irreducible malformations, complications such as reduction loss and fixation failure may occur, necessitating revision surgery. The posterior facet joint distraction and fusion (PFDF) technique, offers a solely posterior approach for revisions. Hence, we delineate varied revision scenarios, proposing surgical strategies and technical details to enhance outcomes and mitigate risks, thereby enriching the neurosurgical community's repertoire. Methods: This was a retrospective cohort study, analyzed patient data from Xuanwu Hospital, between 2017 to 2023. All patients had a history of surgical treatment for CVJ malformations, and experienced failure or loss of reduction. The distance from the odontoid process tip to the Chamberlain's line (DCL), the atlantodental interval (ADI), clivus‐canal angle, cervicomedullary angle, width of subarachnoid space, CVJ area, and width of syrinx were used for radiographic assessment. Japanese Orthopaedic Association (JOA) scores and SF‐12 scores were used for clinical assessment. Independent sample t‐tests were employed. A significance level of p < 0.05 indicates statistically significant differences. Results: We analyzed data from 35 patients. For patients who underwent PFDF, the postoperative DCL, ADI, and clivus‐canal angle significantly improved. For all patients, the postoperative cervicomedullary angle, width of subarachnoid space, CVJ area, and width of syrinx all demonstrated significant improvement, indicating the relief of neural compression. All patients showed significant improvement in both symptoms and clinical assessments. Conclusion: Severe atlantoaxial joint locking or ligament contracting are the fundamental cause of reduction and fixation failure. Anterior odontoidectomy is indicated for patients with robust bony fusion of the atlantoaxial joint in an unreduced position. The PFDF technique is safe and effective for patients with incomplete atlantoaxial bony fusion. Preoperative assessment of surgical feasibility and vertebral artery status ensures surgical safety and efficacy. [ABSTRACT FROM AUTHOR]

Background: Objective and subjective outcomes in the direct anterior approach (DAA) and posterior approach (PA) in total hip arthroplasty (THA) were assessed in this study, using the Oxford Hip Score (OHS) as primary outcome. Pain, 3 objective performance-based tests, surgical time, blood loss and length of stay were assessed as secondary outcomes. Methods: Patients with primary end-stage osteoarthritis were prospectively enrolled by shared decision making for the DAA (32 patients) or PA (26 patients). Baseline data were collected preoperatively and outcomes postoperatively at 2-, 6-, 9- and 12-month follow-up. Results: There is no significant difference (p < 0.05) between the DAA and PA on primary outcome (OHS). There was a main effect of time which indicated an increase of OHS over time independent of group (p < 0.01). Conclusions: In the current study, no significant differences in postoperative functional outcome were found between DAA and PA in all follow-up moments. [ABSTRACT FROM AUTHOR]

Ossification of the posterior longitudinal ligament of the cervical spine (C-OPLL) is a degenerative disorder that leads to the narrowing of the spinal canal and compression of both the spinal cord and nerve roots. This condition is more prevalent in East Asian populations, with marked regional variations in incidence. Symptoms include neck pain, restricted movement, limb numbness, and motor impairment. In severe cases, surgery may be required. Surgical strategies for C-OPLL can be divided into anterior and posterior approaches, each offering distinct advantages and limitations. Anterior approaches, such as anterior cervical corpectomy and fusion (ACCF), anterior cervical discectomy and fusion (ACDF), anterior floating method and vertebral body sliding osteotomy (VBSO), provide the benefit of direct decompression but are technically demanding and carry a higher risk of complications. In contrast, posterior approaches, including laminectomy (with or without instrumented fusion) and laminoplasty (LAMP), offer indirect decompression but may increase the risk of cervical kyphosis. In recent years, innovative techniques like anterior cervical ossified posterior longitudinal ligament en bloc resection (ACOE), anterior controllable antedisplacement and fusion (ACAF), and minimally invasive endoscopic spine surgery have been developed to reduce complications and enhance surgical outcomes. Selecting the appropriate surgical technique requires a thorough assessment of factors such as the severity of the lesion, cervical alignment, and the surgeon's experience. This narrative review examines the differences between these surgical options, discusses their respective advantages and disadvantages, and provides updated insights and recommendations.

The purpose of this study was to evaluate the impact of direct anterior approach (DAA) or posterior approach (PA) on step and stair counts after total hip arthroplasty using a remotely monitored mobile application with a smartwatch while controlling for baseline characteristics. This is a secondary data analysis from a prospective cohort study of patients utilizing a smartphone-based care management platform. The primary outcomes were step and stair counts and changes from baseline through one year. Step and stair counts were available for 1,501 and 847 patients, respectively. Longitudinal regression models were created to control for baseline characteristics. Patients in the DAA group had significantly lower body mass index (P =.049) and comorbidities (P =.028), but there were no significant differences in age (P =.225) or sex (P =.315). The DAA patients had a higher average and improvement from baseline in step count at 2 and 3 weeks postoperatively after controlling for patient characteristics (P =.028 and P =.044, respectively). The average stair counts were higher for DAA patients at one month postoperatively (P =.035), but this difference was not significant after controlling for patient demographics. Average stair ascending speeds and changes from baseline were not different between DAA and PA patients. Descending stair speed was higher at 2 weeks postoperatively for DAA patients, but was no longer higher after controlling for baseline demographics. After controlling for baseline characteristics, DAA patients demonstrate earlier improvement in step count than PA patients after total hip arthroplasty. However, patient selection and surgeon training may continue to influence outcomes through a surgical approach. [ABSTRACT FROM AUTHOR]

Background: Medial hamstring tendons harvesting can be performed through either an anterior or a posterior approach. It has been suggested that using a posterior approach may result in a longer length of harvestable tendon compared with an anterior approach. Hypothesis: There would be no difference in the length of the harvestable tendon between the anterior and posterior approaches. Study Design: Case-control study; Level of evidence, 3. Methods: A retrospective study was conducted at the primary institution using prospectively collected data from skeletally mature Chinese patients who underwent medial hamstring tendons harvesting between January 2008 and December 2021. Patients were excluded if they had experienced graft harvesting complication or if only 1 medial hamstring tendon was harvested. One-to-one exact matching was performed between the 2 approaches based on body height and sex. The outcome assessed was the length of the harvested tendon. Results: A total of 536 patients underwent medial hamstring tendons harvesting using an anterior approach, while 58 underwent it using a posterior approach, all of whom met the inclusion criteria. A group of 54 matched pairs were identified. The length of the harvested semitendinosus tendon was 263 ± 29 mm in the anterior approach and 256 ± 28 mm in the posterior approach (P =.09; Student t test). The mean difference in the length of the harvested semitendinosus tendon between the 2 approaches was 7 mm. The length of the gracilis tendon was 226 ± 29 mm and 223 ± 29 mm in the anterior approach and the posterior approach, respectively (P =.30; Student t test). Conclusion: In a retrospective 1:1 case-control study with exact matching of body height and sex, it was found that there was no difference in the length of the semitendinosus tendon and the gracilis tendon harvested using a posterior approach compared with an anterior approach. The mean difference between the 2 approaches was 7 mm for the semitendinosus tendon and 3 mm for the gracilis tendon, respectively. [ABSTRACT FROM AUTHOR]

Retrorectal tumors (RRT) include diseases that are difficult to diagnose owing to their unspecific and overlapping symptoms. There is a significant lack of literature about approaches to these retrorectal tumors. Usually asymptomatic, when symptoms occur, they may manifest as mass effects, i.e., back pain, altered bowel or bladder function, numbness in lower extremities, or abdominal pain. It is imperative to differentiate them from low rectal cancers as the treatment modalities differ considerably. The majority of these tumors are excised using an anterior approach. In this case report, we aim to highlight the importance of the posterior approach for pelvic tumors as a feasible option for a specific category of RRT. Here we present the case of a 42-year-old male who experienced constipation and dyschezia for 4 years. Upon per rectal examination, a retrorectal mass, not involving the rectal wall, was identified and was surgically excised using a posterior approach as described by Kraske. [ABSTRACT FROM AUTHOR]

Posterior approaches, particularly the Kocher-Langenbeck approach, remain the workhorses in the treatment of acetabular fractures. Various modifications have been developed, each offering specific advantages depending on surgical requirements. The modified Gibson approach, for example, is suggested to provide enhanced visualization of the superior acetabulum, although recent cadaveric studies have not consistently substantiated this benefit. The Ganz approach, which involves bigastric trochanteric osteotomy with safe surgical hip dislocation, is particularly advantageous for managing complex and comminuted posterior acetabular fractures, as it enables a 360° view of the acetabulum and femoral head. Overall, posterior approaches are associated with low rates of complications, with heterotopic ossification being the most prevalent. The choice of surgical approach and patient positioning should be guided by the surgeon's preference and expertise, tailored to the specific fracture pattern and patient characteristics.

According to the two surgical procedures, patients were divided into two groups: 1) anterior group (n=15) and 2) posterior group (n=15). We compared the two groups regarding age, gender, body mass index, affected segments, past history (cardiovascular and cerebrovascular diseases, respiratory diseases, endocrine system diseases, metabolic diseases, and tuberculosis history), smoking history, drinking history, operation time, postoperative bleeding, postoperative drainage, postoperative time, postoperative complications (dural tear, lower limb intermuscular vein thrombosis, lower limb deep vein thrombosis, sinus infection, postoperative recurrence rate), and waist VAS score before and after surgery, waist ODI score, and JOA score.Results: The intraoperative blood loss was significantly less in the posterior group than in the anterior group, and the difference was significant (P < 0.05); the lumbar VAS score was lower in the posterior group than in the anterior group, and the difference between the two groups was significant (P < 0.05). The analysis of the remaining data showed no significant difference between the two groups (P> 0.05), indicating that the efficacy of the two procedures was the same.Conclusion: In the treatment of thoracolumbar tuberculosis disease, there is no significant difference in the clinical efficacy of anterior surgery and posterior surgery. Intraoperative bleeding in posterior surgery was less than in anterior surgery, but the latter showed a significant improvement in postoperative pain relief. Therefore, spinal surgeons should choose the corresponding surgical treatment according to the actual situation of the patient in order to maximize the efficacy.Keywords: thoracolumbar spine tuberculosis disease, anterior approach, posterior approach, lesion removal

Mohammed A Abdelraheem Orthopedic Surgery Department, Gezira Centre of Trauma and Orthopedic Surgery, Wad Madani, Gezira State, SudanCorrespondence: Mohammed A Abdelraheem, Email mohammed.abdelraheem@hotmail.comBackground: Supracondylar humeral fracture (SCHF) is a common injury in children, and early treatment provides excellent results and prevents disabilities. Delayed presentation is still prevalent, mainly in developing countries, because many factors hinder the opportunity to receive appropriate treatment. Currently, there are no standard treatment protocols, and there is insufficient published literature on this topic. This study aimed to evaluate the effectiveness and outcomes of open reduction and Kirschner wire fixation using a triceps-sparing posterior approach in neglected cases with complicated fractures.Methods: This was a prospective multicenter clinical study conducted between July 2016 and June 2021, which included 28 pediatric patients with neglected SCHF who presented to the hospital for definitive treatment five days or more after initial trauma without previous surgical intervention. All the patients underwent open reduction and K-wire fixation using a posterior triceps-sparing approach. The final functional outcome was assessed using the Mayo Elbow Performance Index (MEPI) and Flynn criteria.Results: All fractures (100%) united within 3– 5.5 weeks (mean 4 ± 0.7 weeks). Excellent scores observed in 67.9% (n = 19), good in 21.4% (n = 6), fair in 7.1% (n=2), and poor in 3.6% (n = 1) patients according to MEPI. Correspondingly, Flynn’s criteria showed 96.4% (n = 27) satisfactory and 3.6% (n = 1) unsatisfactory outcome.Conclusion: Open reduction and fixation using Kirschner wires through the posterior triceps-sparing approach is an effective treatment method for late-presenting SCHF in children with consequent satisfactory results.Keywords: children, neglected, triceps-sparing, posterior approach, Kirschner wires

Purpose: The concept of a superior approach (SA) involves the use of a tissue-sparing posterior approach (PA), with exposure of the piriformis muscle and gluteus medius/minimus muscles. The objective of this study was to clarify the features of hip hemiarthroplasty (HA) using a SA in regard to early recovery and mid-term outcomes, with a comparison of the outcomes of SA-HAs and HAs using a PA (PA-HAs). Materials and Methods: A total of 120 HAs for treatment of primary femoral neck fracture with a healthy opposite hip joint were performed in our hospital from 2013 to 2018. Propensity score matching in regard to age, sex, body mass index, walking ability before injury, place of residence, time to surgery, and American Society of Anesthesiologists-Physical Status was performed for 79 patients with SA-HAs and 41 patients with PA-HAs. The final analysis included 34 patients who underwent SA-HAs and 34 patients who underwent PA-HAs. Results: The duration of surgery was 57.1 minutes and 72.1 minutes (P =0.001) for SA-HAs and PA-HAs, respectively. The scores for walking ability at postoperative one week were 4.9±1.4 and 4.2±1.0 (P =0.021) for SA-HAs and PA-HAs, respectively. The Barthel index (BI) at the start of rehabilitation was 26.2±18.7 and 17.4±16.3 (P =0.042) for SA-HAs and PAHAs, respectively. The 4-year complication-free survival rates were 74.2% and 56.3% for SA-HAs and PA-HAs, respectively (P =0.310). Conclusion: SA-HA can be performed without torsion of the muscles and ligaments around the hip joint. Early recovery of walking ability and BI was a significant feature of SA-HAs.

Purpose: Posterior soft tissue repair is one of the methods for preventing dislocation after total hip arthroplasty (THA). This study aimed to evaluate durability of two separate suture materials in THA patients who underwent posterior soft tissue repair. Methods: 42 THA patients were included in the study. The patients were randomly divided into two groups, where braided nonabsorbable suture was used in group A (n = 22), while braided absorbable suture was used in group B (n = 20). While repairing the posterior soft tissues, the piriformis and triceps coxae tendons together with the capsule were reattached to the greater trochanter via pull out sutures. Two hemoclips were attached as distance markers to both pull out sutures on the medial and lateal sides of the greater trochanter. Anteroposterior radiographs were taken one day, 15 days, 3 months and 6 months after operation. Distances between the hemoclips medial and lateral to the greater trochanter were measured on the radiographs, and the closest distances were recorded. The repair was considered a failure if the difference of distances between the first and any of the follow-up measurements exceeded 15 mm. Results: No statistically significant difference was observed between the groups. In both groups, elongation magnitudes in all time intervals were statistically significant while the results obtained from measurements taken 15 days after operation were more significant (p < 0.01). No dislocations were observed. Conclusion: We conclude that for transosseous posterior soft tissue repair in THA, both absorbable and nonabsorbable sutures are similarly durable and can be routinely performed.

The direct anterior approach (DAA) and posterior approach (PA) for total hip arthroplasty (THA) have advantages and disadvantages, but their physiologic burden to the surgeon has not been quantified. This study was conducted to determine whether differences exist in surgeon physiological stress and strain during DAA in comparison to PA. We evaluated a prospective cohort of 144 consecutive cases (67 DAA and 77 PA). There were 5, high-volume, fellowship-trained arthroplasty surgeons who wore a smart-vest that recorded cardiorespiratory data while performing primary THA DAA or PA. Heart rate (beats/minute), stress index (correlates with sympathetic activations), respiratory rate (respirations/minute), minute ventilation (L/min), and energy expenditure (calories) were recorded, along with patient body mass index and operative time. Continuous data was compared using t -tests or Mann Whitney U tests, and categorical data was compared with Chi -square or Fischer's exact tests. There were no differences in patient characteristics. Compared to PA, performing THA via DAA had a significantly higher surgeon stress index (17.4 versus 12.4; P <.001), heart rate (101 versus 98.3; P =.007), minute ventilation (21.7 versus 18.7; P <.001), and energy expenditure per hour (349 versus 295; P <.001). However, DAA had a significantly shorter operative time (71.4 versus 82.1; P =.001). Surgeons experience significantly higher physiological stress and strain when performing DAA compared to PA for primary THA. This study provides objective data on energy expenditure that can be factored into choice of approach, case order, and scheduling preferences, and provides insight into the work done by the surgeon.

Case: A 28-year old male patient was involved in a RTA and sustained a highly comminuted L4 burst fracture with more than 90% canal compromise. Considering the complete loss of power in the respective myotomes but the preservation of sacral sparing there were controversially different surgical options. We successfully performed a posterior only surgical procedure, which applied a modified transpedicle access technique to decompress the spinal canal and to restore the anterior column, achieving full neurological recovery at the final follow-up. Conclusion: A well-planned and executed posterior surgery alone can achieve excellent clinical and radiological result in the treatment of severely comminuted lumbar fractures.

Purpose: Surgical treatment for atlantoaxial instability in pediatric patients is challenging. We report our experience with posterior intra-articular distraction technique in treating this disorder. Methods: This is a retrospective descriptive study which included 15 patients of atlantoaxial instability whose age was less than 16 years at the time of clinical presentation. All patients underwent anterior soft tissue released through a posterior-only approach, followed by intra-facet cage implantation, cantilever correction, and instrumentation. Clinical results were measured using the Japanese Orthopedic Association (JOA) scale and radiographic measurements including the atlantodental interval (ADI), posterior atlantodental interval (pADI), the distance of odontoid tip above Chamberlain's line, clivuscanal angle (CCA), and triangular area (TA) of craniovertebral junction. Results: The follow-up period ranged from 18 to 72 months, with an average of 41.2 ± 15.2 months. The JOA score increased from 13.6 ± 2.3 to 16.6 ± 0.8. ADI decreased from 4.31 ± 2.37 to 1.85 ± 1.09 mm, and TA decreased from 261.96 ± 107.99 to 197.12 ± 72.37 mm2. pADI increased from 12.89 ± 3.52 to 18.25 ± 3.89 mm, and CCA improved from 132.19 ± 16.34 to 144.35 ± 13.91°. All changes in measurements showed statistically significant. There were no evidence of surgery-related complications or iatrogenic secondary cervical deformity during follow-up. Radiological evaluation showed satisfactory corrections and bony fusions of C1–2 facet joint in all cases. Conclusion: Posterior intra-articular distraction followed by cage implantation and cantilever correction can be one of the safe and effective ways to solve atlantoaxial instability in pediatric patients.

Objective To compare the clinical outcomes of transoral anterior Jefferson-fracture reduction plate (JeRP) and posterior screw rod (PSR) surgery for unstable atlas fractures via C1-ring osteosynthesis. Methods From June 2009 to June 2022, 49 consecutive patients with unstable atlas fractures were treated by transoral anterior JeRP fixation (JeRP group) or PSR fixation (PSR group) and followed up at General Hospital of Southern Theatre Command of PLA; 30 males and 19 females were included. The visual analogue scale (VAS) score, Neck Disability Index (NDI), distance to anterior arch fracture (DAAF), distance to posterior arch fracture (DPAF), lateral mass displacement (LMD), Redlund-Johnell value, postoperative complications, and fracture healing rate were retrospectively collected and statistically analyzed. Results Compared with that in the PSR group, the bleeding volume in the JeRP group was lower, and the length of hospital stay was longer. The VAS scores and NDIs of both groups were significantly improved after surgery. The postoperative DAAF and DPAF were significantly smaller after surgery in both groups. Compared with the significantly shorter DPAF in the PSR group, the JeRP group had a smaller DAAF, shorter LMDs and larger Redlund-Johnell value postoperatively and at the final follow-up. The fracture healing rate at 3 months after surgery was significantly greater in the JeRP group (p < 0.05). Conclusion Both C1-ring osteosynthesis procedures for treating unstable atlas fractures yield satisfactory clinical outcomes. Transoral anterior JeRP fixation is more effective than PSR fixation for holistic fracture reduction and short-term fracture healing, but the hospital stay is longer.

BACKGROUND: In the selection of minimally invasive total hip arthroplasty approaches, there is considerable debate about whether direct anterior and posterior approaches differ in postoperative gait, limb balance, and hip motor capacity, and therefore further investigation is warranted. OBJECTIVE: To assess the gait and hip ambulation ability of direct anterior and posterior approaches for primary unilateral total hip arthroplasty with a prospective randomized controlled study. METHODS: A total of 61 patients with unilateral avascular necrosis of the femoral head in Qingdao Municipal Hospital from January 2019 to June 2020 were included in the study. There were 40 males and 21 females, at a mean age of (64.83±5.52) years. All the patients were randomly divided into a direct anterior approach group (n=28) and a posterior approach group (n=33), and received initial total hip arthroplasty by direct anterior approach and posterior approach, respectively. Gait analysis (gait time-space parameters such as stride length, stride frequency, single-leg support time, and plantar pressure difference) and hip ambulation ability (standing-walking timing test and 2-minute walking test) were performed before and 1, 3 and 6 months after operation. RESULTS AND CONCLUSION: (1) With the extension of postoperative time, gait time-space parameters in both groups were gradually improved. The stride length, stride frequency, single-leg support time, and plantar pressure difference in the direct anterior approach group were significantly better than those in the posterior approach group 1 month after surgery (P < 0.01). The stride frequency, single-leg support time, and plantar pressure difference in the direct anterior approach group were significantly better than those in the posterior approach group 3 months after surgery (P < 0.05). The plantar pressure difference in the direct anterior approach group was significantly better than that in the posterior approach group 6 months after surgery (P < 0.01). (2) With the extension of postoperative time, the results of the standing-walking timing test and 2-minute walking test were gradually improved in both groups. The results of the standing-walking timing test and 2-minute walking test 1 and 3 months after operation in the direct anterior approach group were better than those in the posterior approach group (P < 0.05). (3) The results have indicated that the recovery of postoperative gait and hip ambulation ability of the two groups is inconsistent. The direct anterior approach group has some advantages in the improvement of postoperative gait and hip ambulation ability compared with the posterior approach group in the early postoperative period.

Study Design: Systematic review. Objective: To compare the efficacy of the posterior approach and combined anterior-posterior approach in the treatment of ankylosing spondylitis (AS) with cervical spine fracture by meta-analysis. Methods: The databases PubMed, Web of Science, Embase, and Cochrane Library were searched for studies on the comparison of the posterior approach group and the combined anterior-posterior approach group in the treatment of ankylosing spondylitis combined with cervical spine fracture from database establishment to August 2023. The procedure time, intraoperative blood loss, the rates of neurological improvement, mean change in the postoperative neurological function, complication rates, rates of revised surgery, and mortality were extracted. Meta-analysis was performed using RevMan 5.4 software provided by Cochrane Library. Results: A total of 11 retrospective cohort studies with a total of 215 patients were included in this study. The posterior approach group had lower intraoperative blood loss than the combined anterior-posterior approach group [Mean difference (MD) = -146.05, 95%CI(-187.40,-104.69), P <.00001]; the operation time was significantly less in the posterior approach group than in the combined anterior-posterior approach group [MD = -95.34, 95%CI(-113.13,-77.55), P <.00001]. There were no statistically significant differences in the neurological improvement rates, mean changes in postoperative neurological function, complication rates, modified surgery rates, and mortality rates. Conclusion: Both the posterior approach and combined anterior and posterior approach can achieve good results. Clinicians should develop an individualized approach based on the patient's fracture type, degree of spinal cord injury, fracture stability, fracture dislocation, general condition, and underlying disease.

Background: Patients undergoing total hip arthroplasty (THA) with the direct anterior approach (DAA) may experience faster recovery but may also have better baseline health than those who undergo THA with the posterior approach (PA). This study aimed to compare patient-reported outcome measures (PROMs) between the DAA and PA while controlling for baseline factors. Methods: This is a secondary data analysis from a prospective cohort study of patients utilizing a smartphone-based care management platform following THA. The primary outcomes were HOOS JR and EQ-5D-5L through 1 year and change from baseline. Longitudinal regression models were created to control for baseline characteristics and investigate the impact of surgical approach on PROMs. Results: Of 1364 THAs evaluated, 731 (53.6%) were female, and 840 (61.6%) used the PA. Patients in the PA group were of similar age but had higher body mass index and comorbidity scores. Pre-operative HOOS JR and EQ-5D-5L were comparable, but higher post-operatively in the DAA group through 6 months (p = 0.03 and p = 0.005). At 1 year post-operatively, HOOS JR and EQ-5D-5L did not vary between groups (p = 0.48 and p = 0.56), nor did changes from baseline (p = 0.47 and p = 0.11). After controlling baseline characteristics, DAA was significantly associated with higher average HOOS JR through 6 months (p = 0.03) and EQ-5D-5L through 3 months (p = 0.005), but not at 12 months (p = 0.89 and p = 0.56). Conclusion: THA patients undergoing DAA demonstrate earlier improvements in HOOS JR and EQ-5D-5L. However, these differences may not be clinically significant and are not evident at 1-year post-operative. Patient selection and surgeon training may continue to affect outcomes by surgical approach.

Surgical outcomes of open anterior and open posterior approaches, for thoracolumbar A3 to C3/AO type fractures, are compared. A PubMed search was conducted from 1990 to 2024 related to anterior, posterior, and combined approaches. Inclusion criteria: Fresh traumatic T10 to L2 fractures, age ≥13 years, ≥10 cases, minimum follow-up 6 months. Exclusion criteria: Cadaveric studies, pathological fractures, reviews, thoracoscopy-assisted, mini-open lateral (MOLA) and minimal invasive anterior or posterior approaches. Coleman Methodology Scores (CMS) (modified for spinal trauma) indicated potential selection bias in the selected studies. PRISMA guidelines were adapted. Nineteen studies with 847 participants were selected. The average CMS quality score was fair. The anterior approach, although it better decompresses the compromised spinal canal, it is also associated with increased surgical complications compared to the posterior approach. The neurological outcome, the loss of correction and the reoperation rate, were similar to both approaches. This systematic review favors posterior approach. The anterior approach is demanding and is associated with a higher rate of surgical complications compared to the posterior approach. The limitations of the selected studies included inconsistence in the: 1) approaches selection, 2) classifications of the fracture types and the neurological status and 3) variety of instrumentations used.

Background: Spinal tuberculosis, predominantly affecting the thoraco-lumbar region, often requires surgical intervention when conservative treatments fail. This study evaluates the effectiveness of the posterior approach debridement, decompression, and stabilization with pedicle screw fixation in patients with thoraco-lumbar spinal tuberculosis. Methods: A prospective study was conducted on 17 patients, with surgical outcomes assessed through kyphotic angle correction, ESR, VAS, and ODI scores. Results: Post-operative results demonstrated a mean kyphotic angle correction of 12 degrees. ESR levels significantly decreased from a pre-operative mean of 37 mm/h to 9 mm/h post-operatively. Pain and functional disability also improved markedly, with VAS scores reducing from 6.0 to 0.6, and ODI scores from 34 to 3. Conclusion: The posterior approach for thoraco-lumbar spinal tuberculosis is effective in achieving significant spinal alignment correction, reducing inflammation, and improving pain and functional outcomes. This study supports its use as a viable surgical option in appropriately selected patients. [ABSTRACT FROM AUTHOR]

We evaluate the efficacy, safety and indications of single stage posterior release, reduction, and fixation of basilar invagination (BI) with irreducible atlantoaxial dislocation (IAAD). Seventeen patients with BI and IAAD consecutively underwent one-stage release, reduction, and fixation by a posterior approach from July 2000 to June 2015 were followed up for at least 12 months. There were 8 males. Mean age was 56 35.2 ± 13.8 years (range 12–56). The clinical symptoms and signs of the patients were recorded. Pre- and postoperative imaging examinations were performed. Neurological function was assessed using the Japanese Orthopedic Association (JOA) and Ranawat scores. Average follow-up time was 47.4 months (12–97 months). The JOA score increased from preoperative 4–10 (8.06 ± 2.52) to postoperative 13–16 (15.20 ± 0.62). The preoperative Chamberlain line, McRae line, Wackenheim line, atlantodens interval, and cervico medullary angle were 12.52 ± 5.17 mm, 6.59 ± 3.04 mm, 6.96 ± 4.32 mm, 9.88 ± 1.93 mm, and 115.35 ± 12.40°, respectively. The postoperative values were 2.0 ± 3.67 mm, −3.06 ± 1.85 mm, −1.76 ± 2.88 mm, 1.17 ± 1.18 mm, and 136.76 ± 11.44°, respectively. One-stage release, reduction, and fixation for patients with BI and IAAD through a posterior approach is safe and efficient. [ABSTRACT FROM AUTHOR]

ObjectiveA cervical spinal cord injury (CSCI) is a traumatic catastrophe that often leads to neurological dysfunction. The optimal surgical procedure for the treatment of CSCI remains debatable. The aim of this meta-analysis is to compare the neurological outcomes, complications, and clinical factors between anterior and posterior approach in CSCI treatment.MethodsWe searched PubMed, Embase, Web of Science and Cochrane library from their inceptions to october 2023. Preoperative and postoperative Spinal Injury Association (ASIA) and Japanese Orthopedic Association (JOA) scores, and calculated recovery rates (RRs) were compared between the two strategies, and differences in complication rates, operation time, intraoperative blood loss and length of stay were also analyzed.ResultsA total of five studies containing 613 patients were included, with 320 patients undergoing the anterior approach and 293 patients undergoing the posterior approach. Four of the studies included were retrospective cohort studies of high quality as assessed by the Newcastle Ottawa Scale. Additionally, there was one randomized controlled trial evaluated with the Cochrane Risk of Bias tool. Although both anterior and posterior approaches effectively facilitate spinal decompression and promote good neurological recovery, there was no significant difference in the incidences of neurological dysfunction and complications or other clinical features between the two approaches.ConclusionThere is no evidence thus far supports one approach over the other. Large-scale randomized controlled studies are warranted to further distinguish these two methods.Systematic Review Registrationhttps://www.crd.york.ac.uk/, PROSPERO [CRD42023438831].

Objectives There is no consensus on the treatment of moderate‐to‐severe rigid scoliosis. Anterior release and three‐column osteotomy are excessively traumatic, whereas posterior column osteotomy (PCO) alone results in poor outcomes. An emerging surgical technique, posterior intervertebral release (PR), can release the rigid spine from the posterior approach. This study was performed to compare the multi‐segment apical convex PR combined with PCO and PCO alone in patients with moderate‐to‐severe rigid scoliosis. Methods From June 2021 to June 2022, this prospective study of moderate‐to‐severe (Cobb: 70–90°) rigid scoliosis (flexibility of main curve

Objective At present, intraoperative ultrasound was widely used in spinal surgery. But there have been no reports on the use of intraoperative ultrasound in lateral decubitus position spinal surgery. The authors’ research objective was to describe the applications of intraoperative ultrasound in spinal trauma surgery when performed in the lateral decubitus position. Methods Six patients with polytrauma who underwent surgery for spinal trauma between June 2020 and March 2022 and could not be operated on using a posterior approach in the prone position. All six patients underwent surgery in the lateral decubitus position. During surgery, a capsular bag had been designed and surgical field can be filled with normal saline for acoustic coupling, and then ultrasound was used to observe and guide decompression, and assess injuries of the neural elements such as the spinal cord. The data of preoperative and postoperative (12 months) American Spinal Injury Association impairment scale (AIS), follow‐up time, operation time, blood loss, ultrasound signal change of spinal cord, ultrasound guide decompression, internal fixation (12 months), and fracture healing(12 months) were collected. Results The study included four males and two females whose ages ranged from 19 to 56 years old (41.5 ± 13.06 years old). Follow‐up times ranged from 12 to 20 months (14.33 ± 2.75 months). The operation times ranged from 195 to 248 mins (222.16 ± 16.86 mins). The estimated volume of blood loss ranged from 280 to 450 mL (383.33 ± 55.58 mL). The six cases’ AIS (preoperative vs. postoperative) were A versus A, C versus D, A versus B, B versus B, B versus C, and B versus C. Intraoperative ultrasound was performed successfully in all patients using our designed method. Intraoperative ultrasound observation revealed varying degrees of changes in spinal cord echo in all patients. Intraoperative ultrasound provided excellent assistance in spinal cord decompression during surgery. The surgery was completed successfully with no surgery‐related complications till the last follow‐up. At the time of last follow‐up (median time of 12 months) satisfactory fracture reduction and good internal fixation was confirmed on postoperative computed tomography scans and radiographs. Conclusions The authors represented the technology of intraoperative ultrasound in spinal trauma surgery when performed in the lateral decubitus position. This technology solves how to apply intraoperative ultrasound in lateral decubitus position.

Abstract Objective This meta-analysis was aimed to compare the postoperative clinical outcomes between the supercapsular percutaneously assisted total hip (SuperPATH, SP) and conventional posterior/posterolateral approach (PA) for total hip arthroplasty in patients who have failed conservative treatment for hip-related disorders. Methods PRISMAP guidelines were followed in this systematic review. CNKI, Wanfang, PubMed, Embase, Cochrane, Web of Science databases and the reference list grey literature were searched for studies according to the search strategy. Endnote (version 20) was used to screen the searched studies according to the inclusion and exclusion criterias and extract the data from the eligible studied. RR and 95% CI were used for dichotomous variables and MD and 95% CI were used for continuous variables. All analyses and heterogeneity of outcomes were analysed by Review Manage (version 5.4). Publication bias of included studies was analysed by Stata (version 16.0). Results Thirty-six randomized control studies were included. Compared to PA group, SP group had a shorter incision length, less intraoperative blood loss, a shorter length of hospital stay and do activities earlier. Hip function (HHS) was significantly improved within three months postoperatively. Pain of hip (VAS) was significantly reduced within one month postoperatively. The state of daily living (BI) was significantly improved within three months. Patients' overall health status (SF-36) improved significantly postoperatively. There was no difference in postoperative complications between the two approaches. PA had a shorter operative time and a higher accuracy of prosthesis placement. Conclusion The advantages of SuperPATH include accelerated functional recovery and less trauma associated with surgery. However, it required a longer operative time and implantation of the prosthesis was less accurate than that of PA.

Introduction: To date, the approach that prevails in the open reduction and internal fixation of crescent fracture-dislocations (CFD) remains unknown. This study aimed to compare the outcomes of CFD treated via the anterior or posterior approach. Materials and methods: Data from 64 cases of CFDs openly reduced through an anterior (group A, n = 31) or a posterior (group B, n = 33) approach were retrospectively analyzed. Functional results, reduction quality, residual displacements in the axial and coronal planes, pelvic asymmetry deformity, and correlations between Day's classification were compared. Complications and fracture union were also recorded. All patients were followed up for at least 12 months. Results: The functional scores were similar between the two groups, and all fractures achieved good or excellent reduction postoperatively. In the coronal plane, the excellent/good ratio in group B was higher than in group A. The mean residual displacement in the coronal plane was significantly higher in group A than in group B, with group A showing greater displacement in both planes for Day I fractures and in the coronal plane for Day II fractures. The residual displacement in both planes for Day III fractures was comparable between the groups. The pelvic asymmetry deformity was equal between the two groups and among the different Day's fracture types. Conclusions: Open reduction and internal fixation of CFDs obtained satisfactory outcomes through an anterior or posterior approach. The posterior approach achieved a better sacroiliac joint reduction. The optimal indication for the posterior approach was a Day I fracture, followed by a Day II fracture. No correlation was found between the surgical approach and reduction quality in Day III fractures. [ABSTRACT FROM AUTHOR]

Objectives: There is no consensus on the treatment of moderate‐to‐severe rigid scoliosis. Anterior release and three‐column osteotomy are excessively traumatic, whereas posterior column osteotomy (PCO) alone results in poor outcomes. An emerging surgical technique, posterior intervertebral release (PR), can release the rigid spine from the posterior approach. This study was performed to compare the multi‐segment apical convex PR combined with PCO and PCO alone in patients with moderate‐to‐severe rigid scoliosis. Methods: From June 2021 to June 2022, this prospective study of moderate‐to‐severe (Cobb: 70–90°) rigid scoliosis (flexibility of main curve <25%) involved two groups defined by surgical procedure: the PR group, the patients undergoing PR combined with PCO; and the PCO group, the patients undergoing PCO alone. Follow‐up was at least 12 months. Radiographic results mainly included main curve Cobb, correction of per PR/PCO segment, apical vertebra rotation (AVR) and apical vertebra translation (AVT). Demographics, surgical data, complications were also recorded. Student's independent samples t test and Pearson's chi‐square test were used to compare the differences between groups. Results: Forty patients with an average age of 16.65 years were included (PR group, n = 20; PCO group, n = 20). The main curves averaged 77.56° ± 5.86° versus 78.02° ± 5.72° preoperatively and 20.07° ± 6.73° versus 33.58° ± 5.76° (p < 0.001) at the last follow‐up in the PR and PCO groups, respectively. The mean correction rates were 74.30% and 56.84%, respectively (p < 0.001). The average coronal curve correction was 13.49° per release segment, which was significantly higher than the PCO correction of 6.20° (p < 0.001). The correction of apical vertebra rotation and translation in the main thoracic curve was significantly better in the PR group than in the PCO group (p < 0.05). Several minor complications in the two groups improved after conservative treatment. Conclusion: The multi‐segment apical convex PR combined with PCO offers more advantages than PCO alone in the treatment of patients with moderate‐to‐severe rigid scoliosis. Owing to its excellent corrective effect and few complications, this is a high benefit–risk ratio surgical strategy for rigid scoliosis. [ABSTRACT FROM AUTHOR]

A higher risk of dislocation following total hip arthroplasty (THA) has been reported for the posterior approach (PA) compared to the anterior approach (AA). Dual mobility implants, larger head sizes, and elevated or face-changing liners can reduce the risk for dislocation. It remains unclear whether the component selection is influenced by the surgical approach. This is a retrospective study of 7,048 patients who underwent 7,460 primary THA with either AA or PA for primary hip osteoarthritis or osteonecrosis of the femoral head between 2019 and 2021. A propensity score model based on age, body mass index, height, and American Association of Anesthesiologists Score was applied. There were 2,502 AA-THA matched with 4,958 PA-THA (2,456 1:2, and 46 1:1). Groups were compared with multiple linear regression analyses/multivariate logistic regressions after controlling for American Association of Anesthesiologists Score and body mass index. In a second step, only hips operated by surgeons using both approaches were matched 1:1 (1,204 PA and AA, respectively). The same statistics were performed after controlling for "surgeon". The PA was associated with a more frequent use of dual mobility implants, elevated liners, face-changing liners, as well as heads with 36 mm or larger diameters, and the implanted cups were significantly larger (P <.001, respectively). These findings were consistent for both matched cohorts. The surgical approach impacts the component selection in THA. Patients undergoing PA-THA are more likely to receive implants with larger head size or stabilizing features compared to AA-THA. [ABSTRACT FROM AUTHOR]

Introduction: Retrorectal tumors constitute a rare and heterogeneous group of neoplasms, which are characterized by being located in the so-called retrorectal space. In most cases these are benign lesions. The main imaging test for its characterization and planning its therapy is magnetic resonance imaging. Surgery is generally the treatment of choice, often without preoperative anatomopathological studies, given the potential risk of malignancy of these tumors and the appearance of compressive symptoms during the course. Clinical case: The clinical case of a 34-year-old patient is reported, who consulted for a history of pain in the dorso-lumbar region of months of evolution, accompanied by rectal pain. Magnetic resonance imaging of the abdomen and pelvis was requested, which revealed a retrorectal tumor with imaging characteristics suggestive of teratoma. The resolution was a surgical procedure through a perineal approach, with the diagnosis being confirmed by deferred pathological anatomy. Conclusion: Retrorectal tumors are rare lesions in adults that represent a diagnostic and therapeutic challenge. The surgical approach depends above all on the tumor size and the relationship with the S3 sacral vertebra. In the case presented, a mature retrorectal teratoma, the perineal approach is a valid therapeutic option that allowed correct exposure and tumor resection. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this systematic review and meta-analysis was to compare joint awareness in patients who underwent total hip arthroplasty (THA) via the anterior approach (AA) versus the posterior approach (PA). The hypothesis was that patients who underwent THA via AA would have better forgetfulness of the artificial joint. Methods: A comprehensive search of major literature databases and bibliographic details was conducted to identify studies evaluating the forgotten joint score (FJS-12) in total hip arthroplasty (THA) patients operated through the anterior approach (AA) and posterior approach (PA). Out of 234 studies identified, seven studies met the inclusion criteria for review. The Newcastle–Ottawa Scale was used to evaluate the quality of evidence and the risk of bias in the included studies. The FJS-12 was evaluated at three months, one year, and beyond 2 years. Results: The mean FJS-12 at > 2 years was 82.03 in the AA group and 80.32 in the PA group. The forest plot analysis (n = 819 patients) revealed no significant difference in FJS-12 score between these two approaches (MD 2.13, 95% CI [− 1.17, 5.42], p = 0.21; I2 = 60%). However, the joint awareness was significantly lesser in the AA group at 3 months (MD 12.56, 95% CI [9.58, 15.54], p < 0.00001, I2 = 0%) and 1 year (MD 9.55, 95% CI [7.85, 11.24], p < 0.0001, I2 = 0%). Conclusions: After analyzing the available literature, it was found that THA patients operated through the AA approach have significantly lower joint awareness than those operated through the PA approach in the first year of surgery. However, there is no significant difference in joint awareness between these two approaches after 2 years. Level of evidence: III. [ABSTRACT FROM AUTHOR]

Multiple surgical approaches are used for primary total hip arthroplasty (pTHA) and revision total hip arthroplasty (rTHA). This study sought to investigate prevalence of discordance of pTHA and rTHA surgical approaches and to evaluate how approach concordance impacts postoperative outcomes. A retrospective review of patients who underwent rTHA from 2000 to 2021 was conducted at 3 large urban academic centers. Patients who had minimum 1-year follow-up post-rTHA were included and grouped based on whether they received pTHA via a posterior (PA), direct anterior (DA), or laterally based (DL) approach, and by concordance of index rTHA approach with their pTHA approach. Of the 917 patients studied, 839 (91.5%) were included in the concordant cohort and 78 (8.5%) in the discordant cohort. Patient demographics, operative characteristics, and postoperative outcomes were compared. Discordance was most prevalent in the DA-pTHA subset (29.5%), compared to the DL-pTHA subset (14.7%) or PA-pTHA subset (3.7%). Discordance varied significantly between primary approaches among all revisions, with DA-pTHA patients having the highest discordance rate for patients revised for aseptic loosening (46.3%, P <.001), fracture (22.2%, P <.001), and dislocation (33.3%, P <.001). There were no differences between groups in dislocation rate, re-revision for infection, or re-revision for fracture. The results of this multicenter study showed patients who received pTHA via the DA were more likely to receive rTHA via a discordant approach compared to other primary approaches. Since approach concordance did not impact dislocation, infection, or fracture rates after rTHA, surgeons can feel reassured using a separate approach for rTHA. Retrospective Cohort Study.

Prosthetic joint infection (PJI) is a devastating complication of total hip arthroplasty (THA). This study aimed to determine if the anterior approach (AP) influenced the incidence of early PJI in THA compared to posterior approach (PP). Record linkage was performed between state-wide hospitalization data and a national joint replacement registry to identify unilateral THA performed via the AP or PP. Complete data on 12,605 AP and 25,569 PP THAs were obtained. Propensity score matching (PSM) was undertaken to match covariates between the approaches. Outcomes were the 90-day PJI hospital readmission rate(using narrow and broad definitions) and 90-day PJI revision rate (defined as component removal or exchange). The raw PJI readmission rate for AP was lower than PP (0.8% versus 1.1%, respectively). In the PSM analysis, there was no statistically significant difference in PJI readmission rate between approaches using narrow or broad definition of PJI readmission. In terms of revision for infection, both methods showed AP had a significantly lower rate than PP, with an adjusted odds ratio (OR) of 0.47 (95% confidence interval (CI) 0.30, 0.75) for the 1:1 nearest neighbor method and 0.50 (95% CI 0.32, 0.77) for the subclassification method. After addressing known confounders, there was no significant difference in the 90-day hospital readmission rate for hip PJI between approaches. There was a significantly reduced 90-day PJI revision rate for AP. The difference in revision may reflect differences in the surgical management of PJI between hip approaches rather than a difference in the underlying rate of infection. [ABSTRACT FROM AUTHOR]

Introduction: Thoracoscopic superior-segment (S6) segmentectomy is a simple procedure. However, it is applicable only when an interlobar fissure approach is applied, which can sometimes be challenging in cases with a fused interlobar fissure. Herein, we discuss our experience in performing thoracoscopic left S6 segmentectomy in a pediatric patient with congenital pulmonary airway malformation (CPAM) involving a fused interlobar fissure. Case presentation: A 5-year-old girl was prenatally diagnosed with a cystic mass in her left thorax and suspected to have a congenital pulmonary airway malformation. No postnatal respiratory symptoms were observed; elective surgery was performed after reaching the age when differential lung ventilation became feasible. Multiportal complete thoracoscopic surgery was performed under general anesthesia. A large cyst was identified in S6, and the interlobar fissure was fused; thus, we performed a fissure-last S6 segmentectomy using a posterior approach. We first manipulated the vein by retracting the lower lobe anteriorly thus enabling us to identify the segmental veins (V6), and subsequently divide V6a and V6c. We divided segmental arterial branches and separated the intersegmental plane between the S6 and basal segment along V6b using staplers. Lastly, the fused interlobar fissure was divided using a stapler. No postoperative leakage was observed, and the chest tube was removed on the evening of the day of surgery. Pathological examination revealed CPAM type 1 with no malignant findings. The patient survived and is living without any complications 16 months postoperatively. Conclusion: The fissure-last method may be an alternative treatment for patients with incomplete interlobar fissures.

Purpose: The ideal operative treatment of displaced intracapsular femoral neck fractures in the active elderly is contentious. Recent literature favours a better outcome with the use of total hip arthroplasty (THA). Dislocation remains a major concern with THA, especially when a posterior approach is used. More recently, the concept of dual mobility cups is being promoted to avoid dislocations. The aim of the present study was to look at the outcomes of cemented THA utilising the posterior approach for these patients using a 28 ​mm (mm) femoral head. Methods: This study retrospectively analysed the outcome of 108 primary cemented THA, performed by specialist hip surgeons, using a posterior approach with robust soft tissue repair in patients of age 60 years and older presenting with displaced intra capsular femoral neck fractures using a 28 ​mm head. Result: At mean follow-up of 5.2 years (2.0–10.5 years), there were 2 dislocations (1.9%). One underwent manipulation under anaesthesia and the other had application of a posterior lip augmentation device. No other revisions were performed during the follow up period. The 30 day mortality was nil and no post-operative deep infections. Hundred patients (93%) at 1 year follow-up were independently mobilising. Conclusions: With optimal patient selection, an excellent outcome can be achieved for patients with displaced femoral neck fractures using the standard cemented THA via the posterior approach with 28 ​mm head. A robust soft tissue repair and a specialist hip surgeon is recommended for this cohort of patients.

Thoracic ossification of the posterior longitudinal ligament (OPLL) is a rare condition that is mainlyaccompanied by cervical OPLL or ossification of thoracic ligamentum flavum. In case of causing neurologicalmanifestations, it is preferred to treat the condition surgically. Several surgical procedures were introduced,including anterior, posterior, or combined approaches. Laminectomy with instrumented fusion is the mostpopular procedure utilized via the posterior approach. A 32-year-old obese woman, who suffered from backpain and weakness in both lower extremities for one month, was referred to our spine outpatient clinic. Imagingrevealed lower thoracic OPLL (T7/T8 & T8/T9 & T9/T10). The posterior longitudinal ligament had a mixedossification pattern (beaked and continuing cylindrical). To maintain thoracic spine stability and prevent futurekyphosis, we performed laminectomy and long segment fixation (T7 to T12). The post-operative neurologicalexamination revealed a considerable increase in muscle strength and significant pain relief.
