Objective: Due to the low incidence of achondroplasia (Ach), there is a relative lack of research on the treatment and management of spinal complications of Ach. Characteristics and interventions for spinal complications in patients with Ach are in urgent need of investigation. This study aimed to summarize the common spinal complications in patients with Ach and the corresponding treatment strategies.

Methods: This study is a retrospective case series. We retrospectively collected and analyzed Ach cases who presented to our hospital with neurological symptoms due to skeletal anomalies between February 2003 and October 2023. A total of seven patients were included, four males (57.1%) and three females (42.9%) with a mean age of 38.57 years. Patient pain/numbness visual analog scale (VAS), preoperative Oswestry disability index (ODI), development of neurological complaints, and presentation of skeletal abnormalities were collected and followed up routinely at 3, 6, 12 and 24 months postoperatively. The relevant literature was reviewed.

Results: Seven patients were included in this series. The mean preoperative VAS was 4, and the mean preoperative ODI was 50.98%. All patients had concomitant spinal stenosis, four with thoracolumbar kyphosis (TLK), and one with scoliosis. Six of the seven patients underwent surgery, and one patient received conservative treatment. In the routine follow-ups, all patients experienced satisfactory relief of symptoms. Only one of the seven patients developed a new rare lesion adjacent to the primary segments. Six months after the first surgery, a follow-up visit revealed thoracic spinal stenosis caused by ossification of the ligamentum flavum, and his symptoms were relieved after thoracic decompression surgery.

Conclusions: Ach seriously affects the skeletal development of patients and can lead to the development of spinal stenosis, spinal deformities, and other complications of the locomotor system. Surgery remains the primary treatment for complications of the musculoskeletal system. Specific surgical approaches and comprehensive, long-term management are critical to the treatment of patients with spinal complications.

Objective: The sub-acromioclavicular (SAC) decompression is often performed during arthroscopic rotator cuff repair. However, the impact of SAC decompression on patients with postoperative shoulder stiffness (POSS) are controversial and unclear. This study is aim to evaluate the impact of additional sub-acromioclavicular (SAC) decompression during arthroscopic rotator cuff repair on the postoperative shoulder stiffness (POSS) in patients.

Methods: This retrospective study examined digital data from patients with full-thickness rotator cuff tears who underwent arthroscopic rotator cuff repair at a local institution. Patient-reported outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) Score, the University of California-Los Angeles (UCLA) score, and visual analog scale (VAS) scores. Restricted shoulder mobility occurring within 6 months postoperatively, lasting more than 12 weeks, characterized by a passive forward flexion angle of <120° or an external rotation angle of <30°, with or without associated shoulder pain was identified as POSS. Factors affecting POSS were analyzed by binary logistic regression analysis. The patient-reported outcomes scores were analyzed by generalized estimating equations to examine the impact of SAC decompression.

Results: A total of 155 patients met the set criteria and were included in the study. The analysis of binary logistic regression showed that diabetes (p = 0.001) and SAC decompression (p = 0.003) were independent factors for POSS. In the analysis of each follow-up point, only at the 3-month follow-up, the ASES scores (p = 0.003), UCLA scores (p = 0.045), and VAS scores (p = 0.005) showed significant differences between the SAC decompression group and the non-decompression group. For the intergroup comparison, the results showed a significant difference in the ASES scores (β = -4.971, p = 0.008), UCLA scores (β = -1.524, p = 0.019), and VAS scores (β = 0.654, p = 0.010) throughout the study duration between the SAC decompression group and the non-decompression group.

Conclusion: The findings of this study suggested that SAC decompression during arthroscopic rotator cuff repair increase the risk of POSS compared with those without the decompression, which indicate surgeons do not perform SAC decompression unless necessary.

Objective: Accurate and prompt identification of periprosthetic joint infections (PJIs) is critical prior to re-revision arthroplasty to ensure optimal surgical outcomes. Among routinely measured blood indices, red blood cell distribution width (RDW) and platelet count (PLT) have shown strong correlations with infection presence. This study aimed to assess the utility of RDW and PLT for diagnosing PJI in patients scheduled for re-revision arthroplasty.

Methods: This retrospective research encompassed all patients who underwent re-revision hip or knee arthroplasty at our institution from 2008 to 2022. Participants were categorized into either the PJI (n = 41) or the non-PJI (n = 47) group following the guidelines established in the 2013 International Consensus Meeting on PJI. In this analysis, RDW and PLT counts were evaluated alongside conventional inflammatory markers, including C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). The efficacy of these diagnostics was evaluated by the area under the receiver operating characteristic (ROC) curve ([area under the curve AUC]).

Results: RDW demonstrated a modest AUC of 0.678 with sensitivity at 61.0% and specificity at 71.7%, using a threshold of 14.5%. PLT was on par with ESR, showing an AUC of 0.773, and both sensitivity and specificity around 73% at a threshold of 201 × 10⁹/L. CRP presented the highest diagnostic accuracy with an AUC of 0.815, achieving a sensitivity of 82.9% and specificity of 73.9% at a 6.9 mg/L threshold, surpassing ESR's AUC of 0.754. None of the biomarkers, individually or combined, outperformed CRP alone (p > 0.05).

Conclusions: In the context of re-revision arthroplasty, RDW and PLT demonstrate limited efficacy as diagnostic biomarkers for PJI. However, CRP retains its reliability as a biomarker when the diagnostic threshold is appropriately recalibrated.

Objective: The failure rate of foot and ankle soft tissue defect reconstruction with flap is relatively high, often posing a significant burden on patients. The aim of this study is to explore the effectiveness of repeated stretch sutures in repairing skin and soft tissue defects of the ankle and foot.

Methods: Twenty-three patients with ankle and foot skin and soft tissue defects were retrospectively analyzed between February 2016 and February 2019. Sutures were repeatedly stretched every 3-5 days. Local skin grafting was performed if necessary after wound surfaces disappeared or exposed tendons and bones were covered by soft tissue. Wound healing time, postoperative healing area, Vancouver Scar Assessment Scale, sensation, and function of the new skin were evaluated.

Results: Healing time was 17-35 (24.43 ± 5.29) days. Ten patients wholly healed, and 13 healed by approximately 70.08% ± 6.59%. The Vancouver Scar Assessment Scale average score was 2.83 ± 1.19 points, of which 15 cases were excellent (0-3 points) and 8 cases were good (4-7 points). The sensation and function of the new skin after repair were equivalent to those of normal skin after the last follow-up.

Conclusions: Applying repeated tension sutures on the skin and soft defects of the ankle and foot reduced the skin graft area and decreased complex high-risk surgical flaps' use and transplantation area.

Objective: Based on the varying number and relative positions of cervical disc replacement (CDR) and anterior cervical discectomy and fusion (ACDF) procedures, three-segment hybrid surgery (HS) presents a diverse structural approach. Currently, the potential differential effects of HS with different segment combinations and surgical procedures on overloaded vertebral body (OVB) occurrence remain unexplored. The purpose of this retrospective study is to compare the clinical and radiological outcomes of HS and ACDF in treating cervical degenerative disc disease (CDDD), aiming to provide further insights into OVB.

Methods: This study included patients with three-level CDDD who underwent ACDF or HS at our institution. Eligible patients were divided into three groups: Type I (one-level CDR and two-level ACDF), Type II (two-level CDR and one-level ACDF), and ACDF (three-level ACDF). For radiographic analysis, patients were further divided into the Replacement Segment Group and the Nonreplacement Segment Group based on the presence of replacement segments above and below the OVB. Clinical outcomes were evaluated using visual analog scale (VAS) scores for neck and arm pain, Japanese Orthopedic Association (JOA) scores, and neck disability index (NDI) scores. The cervical radiological parameters assessed included (1) vertebral cross-sectional area (CSA), (2) wedge angle (WA), (3) anterior vertebral height (AH), (4) posterior vertebral height (PH), and (5) Hounsfield unit (HU) values. Statistical methods included paired t-test, ANOVA test, and chi-square test. Independent samples t-test, Mann-Whitney U test, and Wilcoxon signed-rank test were used to compare the differences between two groups according to the results of normal distribution test.

Results: A total of 123 patients, evenly distributed among three groups, were included and were well matched in terms of demographic characteristics. The likelihood of vertebral body collapse (VBC) was notably higher in the ACDF group (41.5%) compared with the Type I (17.9%) and Type II (8.9%) groups (p < 0.01). Following surgery, both at 3 and 6 months, the ACDF group demonstrated higher VAS neck scores and NDI scores compared with the Type I and Type II groups (p < 0.01). Additionally, the WA and AH values of the upper and lower adjacent OVB were consistently lower in the ACDF group than in the Type I and Type II groups at 6 and 12 months and at the final follow-up (p < 0.01). Notably, in the Nonreplacement Segment Group, WA significantly decreased at 12 months postoperatively and at the final follow-up compared with the Replacement Segment Group (p < 0.01).

Conclusions: Three levels of HS appear to reduce stress concentrations and alleviate morphological changes in OVB. The occurrence of more VBC patients with OVB was associated with the use of Zero-P or Zero-P VA implants.

Objective: Potential disadvantages of open technique for talocalcaneal coalition (TCC) include a risk of wound infection, opioid drug dependence, and prolonged hospitalization. The purpose of this study was to retrospectively evaluate the effectiveness and safety of endoscopic resection of the TCC.

Methods: A retrospective study from June 2019 to February 2023was conducted on 16 consecutively admitted patients who were diagnosed by imaging to have TCC for whom conservative treatment had failed and who undergone arthroscopic resection. The mean age of this cohort was 31.56 ± 10.39 years (range, 16-57 years). The mean follow-up period was 38.93 ± 15.69 months (range, 11-59 months). The site of the coalition, comorbidities, satisfaction with treatment, visual analog scale (VAS), and American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale scores were evaluated pre- and postoperatively. Preoperative magnetic resonance imaging (MRI) scans were used to categorize the coalition according to the Lim classification. Postoperative computed tomography (CT) scans were used to assess recurrence. The distribution of TCC cases according to the Lim classification was type I in one case, type II in four cases, and type III in 11 cases.

Results: The site of coalition involved the middle facets in seven patients, the posterior facets in three patients, and both the above sites in six patients. All patients underwent total arthroscopic resection of TCC. An auxiliary mini-incision was made for three patients due to serious tibial nerve compression. Radiographics showed that the coalition disappeared and pain was relieved postoperatively. The mean VAS score decreased from 4.31 ± 1.54 to 1.81 ± 0.98 points (p < 0.001). The mean AOFAS ankle-hindfoot score improved from 65.56 ± 5.82 to 87.31 ± 6.30 points (p < 0.001). Fifteen patients were satisfied with the procedure, and one patient experienced numbness after surgery. No recurrence was reported based on CT scan and clinical results up to the end of the study.

Conclusion: Surgical reconstruction employing total arthroscopic resection of TCC can achieve significant functional and radiographic improvements and symptom relief in selected patients with TCC. Auxiliary mini-incisions were necessitated in complex situations.

Primary patellar dislocation has a certain recurrence rate after either conservative or surgical treatment, and the optimal treatment for patients with primary patellar dislocation of different ages remains unclear. This study aims to compare the clinical efficacy of surgical and conservative treatments for primary patellar dislocation across different age groups. According to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist, we conducted a systematic search for randomized controlled trials. We searched the PubMed, EMBASE, Cochrane Library, and Web of Science databases for randomized controlled trials of primary patellar dislocation treated surgically or conservatively up to January 2023. Data searching, extraction, analysis, and quality assessment were carried out in accordance with the Cochrane Collaboration guidelines. A total of nine studies with 433 patients were included in our study. There was no statistically significant difference between the two treatment modalities in terms of Kujala score, pain score, patient satisfaction, reoperation, and Tegner score. The rate of re-dislocation after surgical treatment is lower than that after conservative treatment. Subgroup analysis based on mean age showed that when the age was >20 years, Kujala scores were higher after surgical treatment than after conservative treatment (p < 0.0001, 95% confidence interval [CI] = 10.41-21.30). When the age was ≤20 years, the difference in Kujala scores between the two treatment modalities was not statistically significant. When the age was >20 years, the recurrence rate of patellar dislocation was lower after surgical treatment than after conservative treatment (p = 0.009, 95% CI = 0.08-0.70). When the age was ≤20 years, the difference in the recurrence rate of patellar dislocation between the two treatment modalities was not statistically significant. When the age of patients with primary patellar dislocation is ≤20 years, both surgical and conservative treatments result in similar clinical outcomes. When the age is >20 years, better clinical outcomes can be achieved by opting for surgical treatment. Therefore, surgery may be a better option for patients with primary patellar dislocation whose age is >20 years.

Objective: The objective of this study was to analyze failed posterior fossa decompression (PFD) in patients with basilar invagination and atlantoaxial dislocation (BI-AAD). Revision surgery in these patients is challenging and has been rarely reported. In addition, the anatomical variations of the vertebral artery increase the risk of revision surgery. Here, we introduce the implementation of a new type of one-stage posterior revision surgery, whose difficulties and effects are summarized.

Methods: A total of 21 patients with BI-AAD who underwent PFD were retrospectively analyzed in our center from November 2017 to April 2021. The revision surgery in all patients was performed through the posterior approach. The Japanese Orthopaedic Association (JOA) score and the Short Term 12 (SF-12) score were employed to evaluate the clinical symptoms and health status. The distance from the tip of the odontoid to Chamberlain's line (DCL), the atlantodental interval (ADI), the clivus-canal angle (CCA), the diameter of the subarachnoid space (DSS), and the craniovertebral junction triangular area (CTA) were assessed radiographically. The pre- and postoperative results were compared by paired t test.

Results: The data of 21 consecutive patients were reviewed, with an average follow-up period of 28 ± 14 months. Postoperative imaging showed effectively reduced compression of BI-AAD. No implant failure or neurovascular injury occurred. Eleven patients had vertebral artery abnormalities, but none had vertebral artery injury. All patients had evidence of bone fusion on the CT scan images within a 12-month follow-up period. The JOA and SF-12 scores were significantly improved 1 year postoperatively (p < 0.001).

Conclusion: Posterior surgery using the technique of interarticular distraction, fusion with cage grafting, and fixation is a safe and effective revision surgery to treat patients with basilar invagination and atlantoaxial dislocation who failed PFD, which will result in good outcome.

Objectives: Understanding the patterns and implications of coexisting musculoskeletal conditions is crucial for developing effective management strategies and improving care for older adults. This study aimed to examine the associations between musculoskeletal multimorbidity burden and trajectory and holistic well-being among middle-aged and older adults.

Methods: This prospective study employed data from nine consecutive waves of the English Longitudinal Study of Aging (ELSA), spanning 2002-2018. We used latent class trajectory models (LCTM) to identify groups based on changes in musculoskeletal multimorbidity status. Subsequently, we employed linear mixed models to investigate the associations between musculoskeletal disease burden, trajectory groups, and seven dimensions of holistic well-being: Activities of Daily Living (ADLs), Instrumental Activities of Daily Living (IADLs), depression, memory, loneliness, social interactions, and life satisfaction.

Results: In total, 5272 participants (mean age: 71.9 years; SD: 8.9) were included in the final analysis. Four distinct trajectories were identified: a low-burden group (48.37%), an emerging group (14.76%), a moderate-burden group (26.00%), and a persistent burden group (10.87%). After adjustment, the findings demonstrate that the musculoskeletal disorder burden significantly impacts ADLs, depression, memory, social interactions, and life satisfaction in middle-aged and older adults, with minor effects on IADLs and loneliness. Moreover, with the escalation of the burden, its impact significantly intensifies (p for trend is < 0.001). Compared with the low-burden group, participants in both the moderate and persistent burden groups exhibited significantly lower capabilities in ADLs, poorer memory, increased social interactions, and lower life satisfaction. The emerging group displayed a similar trend, though without statistically significant results.

Conclusions: Our study suggests that the extent and persistence of musculoskeletal disease burden can significantly affect holistic well-being among middle-aged and older individuals.
