Usefulness of Arthroscopic Treatment of Painful Hip after Acetabular Fracture or Hip Dislocation

Effect of nursing intervention via a chatting tool on the rehabilitation of patients after Total hip Arthroplasty

Background

Nursing intervention following discharge is a long-term rehabilitation process that is essential for improving hip joint function and quality of life in affected patients. This study aimed to assess the effect of nursing intervention via WeChat on the rehabilitation of patients after total hip arthroplasty (THA).

Methods

We conducted a retrospective analysis of 232 patients who underwent THA at our hospital from January 2013 to October 2015. Of the 232 patients, 114 received nursing intervention via telephone (Group A), and 118 received nursing intervention via WeChat (Group B). Furthermore, the Harris hip score and Short-Form 36 (SF-36) health survey score were used to evaluate hip joint function and quality of life in patients in the two groups at discharge and 1, 3 and 6 months following discharge. Moreover, the functional independence measure was applied to assess the recovery of joint function in the patients.

Results

No significant difference was observed in the Harris hip score and the SF-36 health survey score between the two groups at discharge and 1 month following discharge (p > 0.05). However, the Harris hip score and SF-36 health survey score were lower in group A than in group B at 3 and 6 months following discharge (p < 0.05). Furthermore, no obvious difference was observed in terms of functional independence between the two groups at discharge (p > 0.05). However, more individuals were completely independent in group B than in group A at 1, 3 and 6 months following discharge (p < 0.05).

Conclusions

Nursing intervention via WeChat can improve the effect of rehabilitation after THA and promote the recovery of joint function in patients.

Role of arthroscopy for the diagnosis and management of post-traumatic hip pain: a prospective study

The current published literature regarding the role of hip arthroscopy in the diagnosis and management of post-traumatic hip pain is still limited. Therefore, we conducted the present prospective study to determine the value of hip arthroscopy in the diagnosis and management of various causes of hip pain after traumatic conditions. The present study included a prospective cohort of 17 patients with symptomatic post-traumatic hip pain. It was conducted between July 2013 and May 2018. The mean age was 22 (19-29) years and the mean follow-up was 24 (r: 7-36) months. Prior to surgery, every eligible patient underwent assessment of functional status using the Modified Harris Hip Score, Oxford hip score (OHS) and Western Ontario and McMaster Universities Arthritis Index (WOMAC) score. All patients underwent arthroscopic management for their diagnosed pathologies. The most commonly encountered diagnosis was labral tear (58.8%), followed by ligamentum teres tear (35.3%) and loose intra-articular fragments (29.4%). In addition, 52.9% of the patients had associated CAM lesion and 11.8% had associated Pincer lesion. The mHSS, OHS and WOMAC score showed significant improvement in the post-operative period (P < 0.001), all the 17 patients had 100% Patient Acceptable Symptomatic State; only one patient did not achieve minimal clinical importance difference. One case underwent labral debridement for failed labral repair (5.8%), another patient developed maralgia paraesthetica (5.8%). In conclusion, hip arthroscopy is a useful and effective minimally invasive procedure for the diagnosis and management of selected patients with post-traumatic hip pain. Moreover, hip arthroscopy was safe technique with no reported serious adverse events.

Effectiveness of Hip Arthroscopy Performed Simultaneously before Open Reduction and Internal Fixation for Acetabular Fracture and Fracture-dislocation of the Hip

Purpose

This study is performed to evaluate the usefulness of arthroscopic surgery prior to open reduction and fixation surgery to treat acetabular fractures and hip fractures-dislocation.

Materials and Methods

From January 2010 to March 2014, a total of 54 patients with acetabular fractures or hip fractures with dislocation were treated arthroscopically via fracture surface before open reduction and fixation (group 1, n=11), and without hip arthroscopy prior to open reduction and fixation (group 2; n=43). Clinical results were evaluated using Harris hip score (HHS) and visual analogue scale (VAS) pain scores.

Results

The mean age of patients is 43.2 years and there are 10 males and 1 females in group 1. The mean follow-up period is 15 months. The acetabular status of each case was assessed arthroscopically. Bone fragment was performed in 6 cases, and ligamentum teres shrinkage in 1 case. At the final follow up, the mean HHS and VAS pain scores were 78.6 and 2.18, respectively. During follow up, one case of osteoarthritis and one case of heterotopic ossification were identified. At the final follow up, the mean HHS and VAS pain scores were 77.5 and 2.23, respectively. In group 2, oteoarthritis and ectopic ossification were observed in 4 and 1 cases, respectively.

Conclusion

No differences were observed in the clinical outcomes of patients with acetabular fracture or hip fracture-dislocation when treated with or without arthroscopic surgery before open reduction and fixation. However, arthroscopy is thought to be useful for evaluating the joint cartilage surface and fracture fragments more accurately.

Is It Safe to Perform an Early Arthroscopy After a Traumatic Hip Dislocation With an Associated Pelvic Ring Injury? Report of Our Technique

Hip arthroscopy is useful in the treatment of several intra-articular pathologies, however, its use in high-energy hip and pelvis injuries raises concerns about fluid extravasion and stability of the pelvic ring. We present our arthroscopic surgical technique (initial access to the peripheral compartment) to remove intra-articular loose bodies and treat associated lesions, as well as our concerns with the technique, in case of a traumatic hip dislocation associated with a contralateral pelvic ring injury.

Sagittal spinopelvic alignment predicts hip function after total hip arthroplasty

The aim of this study was to investigate the association between preoperative sagittal spinopelvic alignment and postoperative clinical outcomes after total hip arthroplasty (THA). This retrospective study included 92 patients with hip osteoarthritis who underwent primary THA between May 2013 and October 2015. Patients' characteristics, radiographic sagittal spinopelvic parameters and modified Harris Hip Scores, including function scores (gait scores and functional activities scores), were investigated. Multivariate linear regression analysis was performed to determine the associations between each preoperative sagittal spinopelvic parameter and postoperative hip function The preoperative sagittal spinopelvic parameters that were associated with postoperative gait scores were sagittal vertical axis (adjusted β-coefficient=-0.28, P=0.02), lumbar lordosis angle (adjusted β-coefficient=0.29, P=0.0089), pelvic tilt (adjusted β-coefficient=-0.25, P=0.045), sacral slope (adjusted β-coefficient=0.27, P=0.017) and pelvic incidence minus lumbar lordosis angle (adjusted β-coefficient=-0.31, P=0.01). The preoperative sagittal spinopelvic parameters that were related to the postoperative functional activities scores were sagittal vertical axis (adjusted β-coefficient=-0.38, P=0.0051) and pelvic incidence minus lumbar lordosis angle (adjusted β-coefficient=-0.39, P=0.0033). Patients with preoperative imbalanced sagittal alignment such as larger sagittal vertical axis, larger pelvic incidence minus lumbar lordosis and retroversion of pelvis had poorer clinical outcomes than others after THA. While, those preoperative imbalanced patients with anteversion of pelvis may have a compensatory ability which could correct the abnormal sagittal alignment after THA. Preoperative sagittal spinopelvic alignment affected postoperative clinical outcomes after THA.
