A Novel Operation Technique for Forearm Deformities in Patients with Brachial Plexus Birth Injury: Retrospective Analysis of 14 Patients.

Background: We aimed to evaluate the effectiveness of our novel operation technique that included radial shaft shortening plus supination producing osteotomy and transfer of the biceps brachii tendon to the brachialis tendon in patients with chronic radial head dislocation secondary to brachial plexus birth injury (BPBI). Methods: Fourteen patients with chronic radial head dislocation resulting from BPBI were included in this study, with a minimum 1-year postoperative follow-up period. All patients underwent the same surgical procedure. The range of motion of affected elbow was measured with a standard goniometer. The Mayo Elbow Performance Score (MEPS) was used to measure for evaluation of functional result of these patients. The affected elbow radiograph also obtained in the last visit for evaluation of compatibility of the radiocapitellar joint. Results: Fourteen patients (10 males and 4 females) were included in the study. The average age at the time of surgery was 7.2 (5-8) years and average follow-up was 73.2 ± 19 (36-131) months. Although the forearm active-passive pronation decreased, active-passive supination significantly improved postoperatively (p < 0.001). Ten patients had excellent MEPS results (90 and above), two patients with good results (75 and 80), one patient with fair (65) and one patient with poor result (55). Radiocapitellar reduction was achieved in 78.5% (11/14) of the patients. Conclusions: The novel surgical techniques that included radial shaft shortening plus supination producing osteotomy and transfer of the biceps brachii tendon to the brachialis tendon improved the functional outcomes of patients with chronic radial head dislocation secondary to BPBI. Level of Evidence: Level IV (Therapeutic).

Revealing the Effect of Spinopelvic Alignment on Hip Disorders.

Background: Hip osteoarthritis (HOA) is a growing burden and one of the leading causes of hip pain. The relationship between the HOA and the alignment of the spinopelvic region has been intensively studied, however the issue remains controversial. Spinopelvic imbalance, HOA, and dysplasia were investigated in relation to sagittal spinopelvic parameters in this study. Methods: We collected computerized tomography (CT) topograms of the pelvis or abdomen from 380 patients. In antero-posterior (AP) topograms, Tonnis grading, center-edge angle (CEA) and Sharp's acetabular angle (AA) measurements were performed on each patient. Lateral topograms were used to evaluate the following spinopelvic parameters for each patient: pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), sacral table angle (STA), lumbar lordosis (LL), proximal lumbar lordosis (PLL), distal lumbar lordosis (DLL), and PI-LL difference. Initially, the cohort was divided into two subgroups based on whether or not they had HOA. Then, they were divided into two subgroups based on whether or not they had dysplasia. Ultimately, it was divided in half based on the PI-LL imbalance. Statistical analyses were conducted to determine the likely correlations between the spinopelvic parameters of these subgroups. In addition, the correlations between spinopelvic parameters were investigated. Results: There were 380 patients evaluated. We found no association between HOA or dysplasia and spinopelvic parameters. In addition, there was no association between PI-LL imbalance and HOA or dysplasia. Conclusion: There was no difference in constant PI and STA angle, besides other variable parameters, between groups having HOA and dysplasia or not. PI-LL imbalance has no effect on HOA and dysplasia.

The Impact of Spinopelvic Alignment on the Facet Joint Degeneration.

STUDY DESIGN: Retrospective Cohort. OBJECTIVES: This study aims to evaluate the relations between facet joint degeneration (FD) and sagittal spinopelvic parameters. Second, the association of FD with degenerative disc disease (DDD) and lumbar disc herniations (LDH) was assessed. METHODS: The radiologic data of 192 patients was retrospectively analyzed. Total, proximal, and distal lumbar lordosis (LL, PLL, and DLL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), and sacral table angle (STA) were measured on lumbar x-ray plates. DDD and FD was graded on the MRI images. The apex of lumbar lordosis and PI-LL imbalance were noted in each patient. Correlation analyses were performed. RESULTS: Age and body mass index (BMI) were correlated with FD. LL and DLL are positively associated with upper-level FDs (L1-2 and L2-3) (P < 0,05). PLL were positively associated with lower level FD (L5-S1) (P < 0,05). A significant increase in PI was associated with FD in L2-3 and L4-5. A larger PT was found in FD in L4. The PI-LL imbalance was not correlated with the FD. Correlation between DDD and LDH and FD was observed in each level (P < 0,01). The level of FD is not affected by the apex of the curve. CONCLUSION: Age and BMI have a direct impact on FD. However, spinopelvic parameters influence the severity of FD rather than its occurrence. In addition to the effects of lumbar lordosis as a single entity, it is essential to consider separately the effects of proximal and distal lumbar lordosis at the FD level.

Arthroscopic Debridement and Arthrolysis for the Treatment of Advanced Kienböck's Disease: 18-Month and 5-Year Postoperative Results.

Background Salvage procedures, such as proximal row carpectomy, limited or total wrist arthrodesis, and wrist replacement, are generally preferred to treat advanced Kienböck's disease. However, these procedures are particularly aggressive and may have unpredictable results and potentially significant complications. Questions/Purpose This study aimed to present the short- to mid-term clinical and functional results of arthroscopic debridement and arthrolysis in the management of advanced Kienböck's disease. Patients and Methods Fifteen patients in whom Lichtman Stages IIIA to IIIC or IV Kienböck's disease was diagnosed and treated by arthroscopic wrist debridement and arthrolysis were included in this retrospective study. The mean age was 30 years (range: 21-45). The mean follow-up period duration was 36 months (range: 18-60). The Disabilities of the Arm, Shoulder, and Hand (DASH) score, visual analog scale (VAS), wrist range of motion (ROM), and grip strength were measured preoperatively and then again at the final follow-up visit. Results The mean DASH and VAS scores improved from 41 (range: 31-52) and 7.1 (range: 6-8) preoperatively to 13 (range: 8-21) and 2 (range: 0-3; p < 0.001) at the final follow-up visit, respectively. The mean wrist flexion and extension values increased from 32 (range: 20-60 degrees) and 56 degrees (range: 30-70 degrees; p = 0.009) preoperatively to 34 (range: 10-65 degrees; p = 0.218) and 57 degrees (range: 30-70 degrees; p = 0.296) at the final follow-up appointment, respectively, although these findings were statistically insignificant. The mean strength of the hand grip increased from 22.7 (range: 9-33) to 23.3 (range: 10-34; p = 0.372). Conclusion Arthroscopic debridement and arthrolysis may improve wrist function and quality of life due to the preserved ROM and hand grip strength after short- to mid-term follow-up periods despite the radiographic progression of Kienböck's disease. Level of Evidence This is a Level IV, retrospective case series study.

Combined surgical treatment for missed rupture of triceps tendon associated with avulsion of the ulnar collateral ligament and flexor-pronator muscle mass.

Triceps tendon ruptures are rare injuries. Coexistence of ipsilateral ulnar collateral ligament injury is even rarer. Here, we describe an unusual combination injury to elbow of a 39-year-old male construction worker consisting of triceps tendon rupture, avulsion of elbow ulnar collateral ligament and flexor pronator muscle origin ipsilaterally. A simultaneous repair and reconstruction of all damaged structures was proposed with individualized postoperative rehabilitation. Return to pre-injury level of activities obtained with this treatment protocol. High degree of suspicion and careful examination were needed to prevent missed diagnosis and prolonged instability which may be inevitable after inappropriate treatment of such injury.
