Purpose Current operative treatment for advanced thumb carpometacarpal (CMC) joint arthritis mainly constitutes complete trapeziectomy with or without additional stabilizing procedures. However, it is unclear whether the additional procedures influence overall clinical outcomes. Therefore, the purpose of this study was to evaluate the effectiveness of our posttrapeziectomy suture suspensionplasty technique, performed using the abductor pollicis longus and flexor carpi radialis tendons, in patients with advanced thumb CMC arthritis. Materials and Methods We evaluated 36 thumbs of 35 patients with advanced thumb CMC arthritis treated with combined operative excision of trapezium followed by a suture suspensionplasty using flexor carpi radialis and abductor pollicis longus tendons. We used a minimal volar approach to create a sling construct with a nonabsorbable suture material, which could support the thumb metacarpal base without pin fixation or tendon transfer. For radiographic evaluation, we used the ratio of the radial metacarpal subluxation to metacarpal articular width, estimated from the bilateral stress-view radiographic images of the thumb, and calculated the trapezial space ratio by dividing the trapezial space height by the proximal phalangeal length. The clinical outcomes were evaluated using the visual analog scale and disabilities of the arm, shoulder, and hand scores, along with evaluation of the improvement in both postoperative range of motion and strength recovery. Results The mean duration of follow-up was 26 months (range, 18–60 months). The average visual analog scale and disabilities of the arm, shoulder, and hand scores decreased from 5.9 to 0.4 and from 51.6 to 27.0, respectively. The range of motion during palmar abduction and opposition of the metacarpophalangeal joint improved with an increase in mean value from 49.1 degrees to 54.1 degrees, and from 7.8 to 9.3 Kapandji score, respectively. The grip and key pinch strengths showed no significant changes from mean preoperative values of 13.3 kg and 3.8 kg to 13.2 kg and 3.2 kg, respectively, as measured at the 18-month follow-up. Conclusions Our suture suspensionplasty technique has several advantages including minimal invasive approach, short operative time, cost-effectiveness, and early mobilization. We suggest that it can be used as an effective, alternative stabilization method after a complete trapeziectomy.
This study aimed to assess the clinical significance of sagittal balance for predicting and managing the recollapse of cemented vertebra following percutaneous vertebroplasty (PVP) in patients with thoracolumbar osteoporotic vertebral fracture (OVF). Overview of Literature: Recently, the recollapse of cemented vertebra following PVP for OVF has been reported. Although the risk factors for recollapse have been determined, the association between sagittal spinopelvic parameters and sagittal imbalance with recollapse has not been established. Methods: Ambulatory patients who underwent single-level PVP for thoracolumbar OVF with a follow-up of at least 24 months were retrospectively reviewed. The patients were divided into two groups depending on the presence of symptomatic recollapse at the cemented vertebra: (1) recollapsed (RC) group and (2) noncollapsed (NC) group. The patient characteristics and radiographic measurements associated with sagittal imbalance were analyzed at each follow-up visit. Results: Overall, 134 patients (RC group, n=28; NC group, n=106) were enrolled. The mean fracture-free interval was 3.2 months (range, 1.2-25.1 months). The multivariate binary logistic regression analysis identified low bone mineral density (p=0.047), degree of dynamic mobility within the vertebra (p=0.025), and sagittal imbalance as significant risk factors for recollapse (p=0.013; odds ratio, 5.405). The progression of sagittal imbalance and thoracolumbar kyphosis (T10-L2) was more significant in the RC and sagittal imbalance groups than in the NC group (both p=0.000). Conclusions: Sagittal imbalance, lower bone mineral density, and dynamic mobility within the vertebra are associated with the recollapse of cemented vertebrae following PVP. Sagittal imbalance, rather than local kyphosis or thoracolumbar kyphosis, is particularly significant in that it results in more progressive collapse and sagittal deformity and is accompanied by substantial back pain and neurological deficits. Therefore, a stricter and more active management, including anti-osteoporosis medication, is required for the treatment of OVF with sagittal imbalance of the spine.
Background For treating displaced patella fractures, tension band wiring is the most widely used technique. However, implant removal surgery is often necessary to alleviate discomfort caused by fixation materials. On the contrary, fixation using nonabsorbable suture materials is anticipated to result in comparable outcomes without need for further implant removal surgery. However, there is a lack of clinical studies comparing the two fixation techniques (wire and nonabsorbable suture materials) for acute patella fractures. Methods From 2014 to 2018, we retrospectively reviewed 60 patients who underwent open reduction with internal fixation for acute patella fracture. Thirty patients (group 1) who received surgery using tension band wiring and 30 patients (group 2) who received surgery using nonabsorbable suture materials were enrolled. The average follow-up period was more than 1 year after operation. Operation time, postoperative bone union time, range of motion (ROM) of the knee joint, postoperative clinical results, and complications were compared between the two groups. Result Operation time, clinical bone union, and radiologic bone union were not statistically different between groups 1 and 2. At 3 months postoperatively, flexion was 120.3 ± 9.4° in group 1 and 110.5 ± 7.7° in group 2, showing statistically significant difference (p = 0.037). At 6 and 12 months postoperatively, the ROM was similar in both groups. Hospital for special surgery score at 3 months postoperatively was 78.4 ± 8.2 in group 1 and 83.7 ± 8.7 in group 2, showing statistically significant differences (p = 0.032). However, at 6 and 12 months postoperatively, there were no statistical differences. Lysholm score at 3 months postoperatively was 73.5 ± 8.1 in group 1 and 80.4 ± 8.2 in group 2, showing statistically significant difference (p = 0.016), but at 6 and 12 months postoperatively, there were no statistical differences. Conclusion Fixation using multiple nonabsorbable suture materials can be an alternative surgical method in managing patella fractures, along with tension band wiring.
Background Recent studies have demonstrated that the distal forearm dual-energy X-ray absorptiometry (DEXA) scan might be a better method for screening bone mineral density (BMD) and the risk of a distal forearm fracture, compared with a central DEXA scan. Therefore, the purpose of this study was to determine the effectiveness of a distal forearm DEXA scan for predicting the occurrence of a distal radius fracture (DRF) in elderly females who were not initially diagnosed with osteoporosis after a central DEXA scan. Methods Among the female patients who visited our institutes and who were over 50 years old and underwent DEXA scans at 3 sites (lumbar spine, proximal femur, and distal forearm), 228 patients with DRF (group 1) and 228 propensity score-matched patients without fractures (group 2) were included in this study. The patients’ general characteristics, BMD, and T-scores were compared. The odds ratios (OR) of each measurement and correlation ratio among BMD values of the different sites were evaluated. Results The distal forearm T-score of the elderly females with DRF (group 1) was significantly lower than that of the control group (group 2) (p < 0.001 for the one-third radius and ultradistal radius measurements). BMD measured during the distal forearm DEXA scan was a better predictor of DRF risk than BMD measured during the central DEXA (OR = 2.33; p = 0.031 for the one-third radius, and OR = 3.98; p < 0.001 for the ultradistal radius). The distal one-third radius BMD was correlated with hip BMD, rather than lumbar BMD (p < 0.05 in each group). Conclusion Performing a distal forearm DEXA scan in addition to a central DEXA scan appears to be clinically significant for detecting the low BMD in the distal radius, which is associated with osteoporotic DRF in elderly females. Level of evidence III; case-control study.
