ABSTRACT
Objective:To evaluate the trans-subscapularis approach in the treatment of Ideberg type Ⅰa scapular glenoid fractures.Methods:A retrospective analysis was conducted in the 16 patients with Ideberg type Ⅰa scapular glenoid fracture who had been treated via the trans-subscapularis approach at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from December, 2012 to August 2019. X-ray follow-ups were conducted at 2 weeks, 6 to 8 weeks, 3 months and 12 months, and CT follow-ups at 6 to 8 weeks after operation. The Constant-Murley score and visual analogue scale (VAS) were used at the last follow- up to evaluate the postoperative shoulder function and pain in the patients.Results:The 16 patients were followed up for 9 to 101 months (average, 41.2 months). All fractures achieved bony union after 6 to 8 months (average, 6.8 weeks). The Constant-Murley scores at the last follow-up ranged from 85 to 100 points; the lateral internal rotation scores averaged 8.3 points (from 6 to 10 points), showing the level of the T12 spinous process could be palpated by the back of the hand; the VAS scores averaged 0. No patients reported internal fixation failure, postoperative infection or other complications.Conclusion:The trans-subscapularis approach can be used to treat Ideberg type Ⅰa scapular glenoid fractures due to its satisfactory clinical effects.
ABSTRACT
Objective:To evaluate the clinical efficacy of the axillary approach in the treatment of scapular glenoid fracture.Methods:A retrospective analysis was performed of the 12 patients who had been treated for scapular glenoid fracture from November 2019 to April 2021 at Department of Upper Limb Orthopaedics, Zhengzhou Orthopaedic Hospital. They were 4 males and 8 females, aged from 30 to 75 years (mean, 53.5 years). According to the Ideberg classification, there were 2 cases of type Ⅰa, 9 cases of type Ⅱ and one case of type Ⅴa. All cases were treated through the axillary approach. Two patients complicated with anterior shoulder dislocation were treated with manual reduction under anesthesia before operation and the other 10 cases with special plate fixation through the axillary approach. The 3 patients complicated with fracture of greater tuberosity were fixated with a special plate through the lateral shoulder split deltoid approach. Constant-Murley score, visual analogue scale (VAS) and Hawkins grading were used at the last follow-up to evaluate shoulder function, pain and stability after operation.Results:All patients were followed up for 9 to 20 months (mean, 14.4 months). The operation time ranged from 55 to 110 min (mean, 76.3 min), intraoperative bleeding from 60 to 160 mL (mean, 103.8 mL), and hospital stay from 8 to 14 d (mean, 11.1 d). All incisions healed primarily and all scapular glenoid fractures got united 6 months after operation. The last follow-up showed no shoulder instability, neurovascular injury or internal fixation failure. At the last follow-up, the range of motion of the shoulder was 159.2°±26.1° in forward bending, 156.7°±29.6° in abduction, 48.3°± 15.3° in external rotation (neutral position), and 73.3°±12.3° in internal rotation (neutral position), and the Constant-Murley score was (94.0±5.3) points. The range of motion of the shoulder and Constant-Murley score were significantly improved compared with those before operation (10.8°±11.6°, 7.5°±11.4°, 5.8°±10.0°, 42.5°±16.0° and 4.9±4.0, respectively) (all P<0.05). The VAS score was 0 in 11 patients and 2 in one patient at the last follow-up. Conclusion:The axillary approach is feasible for the treatment of scapular glenoid fracture, because it is hidden and less invasive, leading to good clinical outcomes.
ABSTRACT
Objective To investigate method of in vitro measurement of adult Chinese scapula glenoid version angle with MSCT postprocessing technique. Methods Fifty dry scapula specimens and 50 wet anticorrosive shoulder specimens of adult Chinese were scanned with Siemens Somatom Sensation 16 scanner. The scapula glenoid version angle was measured with postprocessing technique of thick or thin multiplanner reformation (MPR), and the data were analyzed statistically. Results The scapula glenoid version angle of dry scapula specimens and wet anticorrosive shoulder specimens was (-0.40±4.10)°, (-3.00±4.49)° with thick MPR, and (-0.34±4.21)°, (-2.70±4.54)° measured with thin MPR, respectively. There was significant difference of the scapula glenoid version angles between the dry scapula specimens and wet anticorrosive shoulder specimens (P0.05). Conclusion Measuring the scapula glenoid version angle with thick MPR of MSCT is simple and fast. The scapula glenoid version angle is markedly variable between the dry scapula specimens and wet anticorrosive shoulder specimens. The retroversion angle of scapula glenoid is about 3°, which should be considered in the design of shoulder prosthesis.
