“…The present report of an adult patient with an a-type spinal deformity is novel in the literature. Reports of patients with Cobb angles greater than 100° are rare, [1][2][3][4][5][6] with the largest series published in 2019 classifying these rare, severe deformities as described previously (Table 1). 1 Alpha-type spinal deformities in general are recalcitrant to correction with halo traction, 1 necessitating surgical intervention to improve function for these patients.…”

This report describes a 42-year-old man who presented with an α-type spinal deformity with a Cobb angle of 224.9° and associated spinal cord rotation greater than 90°. Preoperative imaging revealed extensive spinal deformity, and 3D modeling confirmed the α-type nature of his deformity. Intraoperative photography demonstrated spinal cord rotation greater than 90°, which likely contributed to the patient’s poor neurological status. Reports of patients with Cobb angles ≥ 100° are rare, and to the authors’ knowledge, there have been no published cases of adult α-type spinal deformity. Furthermore, very few cases or case series of spinal cord rotation have been published previously, with no single patient having rotation greater than 90° to the authors’ knowledge. Given these two rarities presenting in the same patient, this report can provide important insights into the operative management of this difficult form of spinal deformity.

“…We can't find more information about the angle loss of correction after cubitus varus osteotomy,but we fonud some literatures had reported that pedicle screw-only fixation in AIS is associated with significantly fewer spinal segments instrumented, shorter operating time, less need for anterior releases, as well as fewer thoracoplasties [21]. However, loss of correction over time in AIS patients can still be a problem [20,22,[26][27][28]. Overall, pedicle screw constructs in AIS appear to have loss of correction approximately half as frequently as hybrid constructs, but still occurs in approximately 10 % of cases [29].…”

Purpose Cubitus varus deformity in the pediatric population is an infrequent but clinically important disease to orthopedic surgeons. Since these patient populations are different in many respects, we sought out to investigate the rates of loss of correction over time as well as the factors associated with loss of correction in pediatric patients undergoing osteotomy for treatment of cubitus varus deformity. Methods Between 2008-7 and 2017-7, we treated 30 cases of cubital varus had underwent the the osteotomy. We compared preoperative and postoperative clinical and imaging parameters (H-cobb angle,Baumman angle) for all patients. Postoperative evaluation was performed by telephone interview.Results In our study,there were 30 patients,included 17 males and 13 females.the mean age was 75 months old.In the first follow-up,Approximately 80 % of patients had a loss of correction of H-cobb，and 83% of patients at the second follow-up. The Baumann angle also had a loss of correction,about 57% was lost at the first follow-up,and 43% was lost at the second follow-up. The average interval between the first follow-up and the second follow-up was 24 days ，The H-cobb angle mean loss was 2.4°.There was a statistically significant difference between the H-cobb angle measured before surgery and the angle measured after surgery (p <0.05). There were significant differences between the two angles. There was no statistically significant difference between the H-cobb angle measured at the third postoperative period and the contralateral healthy elbow H-cobb angle. There was a statistically significant difference between the Baumann angle measured before surgery and the angle measured after surgery (p <0.05). The Baumann angle measured in the second and third postoperative periods was significantly different from that of the contralateral healthy elbow joint. According to the survival curve analysis, we can see that the median survival time of the H-cobb angle and the Baumann angle is 27 and 34 months. Conclusions The postoperative angle loss will last for a period of time, which mainly occurs during the first and second follow-up period . Therefore, it is important to pay attention to the follow-up of the patient for a period of time after the operation, and take measures to avoid rapid angle loss. Angle loss was significantly reduced after the third follow-up. Further study is needed on this subgroup of patients with cubitus varus given the differences in strategies needed to correct and maintain their deformity correction.

“…[23] However, loss of correction over time may still occur in patients with AIS. [24][25][26][27][28] Overall, the use of pedicle screw constructs in AIS resulted in an incidence of loss of correction that was approximately half of that of hybrid constructs, occurring instead in approximately 10% of cases. [29] Although the loss of correction in AIS patients was not solely attributed to bony structure loss, this finding nonetheless provides a valuable insight into loss of correction of the H-Cobb angle in patients with cubitus varus.…”

We aimed to investigate the rate of loss of correction and the factors thereof in pediatric patients undergoing osteotomy for treatment of cubitus varus deformity. Between July 2008 and July 2017, we treated 30 patients who underwent osteotomy for cubital varus. We compared the preoperative and postoperative clinical and imaging findings, including the H-Cobb and Baumman angles, in all patients. Postoperative evaluation was performed by telephonic interviews. Our patients consisted of 17 males and 13 females. The mean age was 75 months. At the first follow-up, approximately 80% of patients had experienced a loss of correction of the humerus-cobb angle (H-Cobb angle); at the second follow-up, the incidence was 83%. Meanwhile, 57% and 43% of patients experienced a loss of correction of the Baumman angle at the first and second follow-ups, respectively. The average interval between the first and second follow-ups was 24 days, and the mean loss in the H-Cobb angle was 2.4°. There was a significant difference between the H-Cobb angles as measured before and after surgery ( P < .05). There was no significant difference between the H-Cobb angles of the affected side and the contralateral healthy elbow at the third postoperative follow-up; however, there was a significant difference between the Baumman angle between before and after surgery ( P < .05). The Baumman angles as measured at the second and third postoperative follow-ups differed significantly from those of the contralateral healthy elbow joint. According to the survival curve analysis, the median survival times of the H-Cobb and Baumman angles were 27 and 34 months, respectively. The postoperative loss of the 2 angles occurred mainly during the first and second follow-up periods. Therefore, patient follow-up is particularly important in the period directly following the operation. Additional measures may be necessary to avoid rapid angle loss.
