Short-term Clinical Results of Manipulation Under Ultrasound-Guided Brachial Plexus Block in Patients with Idiopathic Frozen Shoulder and Diabetic Secondary Frozen Shoulder.
The open orthopaedics journal, 2018Co-Authors: Akira Ando, Junichiro Hamada, Yoshihiro Hagiwara, Takuya Sekiguchi, Masashi Koide, Eiji ItoiAbstract:This study examined the effectiveness of manipulation under ultrasound-guided brachial plexus block in patients with recalcitrant idiopathic Frozen Shoulder and diabetic secondary Frozen Shoulder (diabetic Frozen Shoulder). Forty-four idiopathic Frozen Shoulders and 10 diabetic Frozen Shoulders with failed conservative treatment for at least 3 months were included in this study. The manipulation was performed under ultrasound-guided brachial plexus block and visual analogue scale, range of motion, and Constant scores were measured before manipulation and at the last follow-up examination. No major complications were observed during the procedure. Sufficient improvement was not obtained in two patients during the procedure and to avoid complications, the procedure was discontinued and subsequently arthroscopic capsular release was performed. Visual analogue scale, range of motion towards all directions, and Constant scores were significantly improved after the manipulation in both the idiopathic Frozen Shoulder and diabetic Frozen Shoulder groups, however the diabetic group showed inferior results compared with those of the idiopathic group. This manipulation was effective and shortened the duration of symptoms in most of the idiopathic and diabetic Frozen Shoulders without major complications during the procedure. Diabetic Frozen Shoulder showed inferior clinical results and difficulty in recovery in range of motion, which indicated that diabetic Frozen Shoulder should be discussed as a different entity.

Arthroscopic Coracohumeral Ligament Release for Patients With Frozen Shoulder.
Arthroscopy techniques, 2017Co-Authors: Yoshihiro Hagiwara, Junichiro Hamada, Akira Ando, Takuya Sekiguchi, Masashi Koide, Kenji Kanazawa, Eiji ItoiAbstract:Arthroscopic pancapsular release has been recommended for recalcitrant Frozen Shoulder, but regaining range of motion has not been sufficient compared with the unaffected side. There is no consensus about the reasons for these remaining restrictions in range of motion, but residual capsular or connective tissue must be considered a candidate. A thickened coracohumeral ligament at the rotator interval has been reported as one of the most specific manifestations of Frozen Shoulder. It covers wider portions of the subscapularis tendon, supraspinatus tendon, and infraspinatus tendon than previously reported. We describe an arthroscopic surgical technique for the release of the entire coracohumeral ligament including the subscapularis and supraspinatus portions and the release of the inferior and posterior parts of the glenohumeral ligament using the 7-o'clock portal. These procedures are essential and reliable methods to release the entire joint capsule to regain full range of motion for Frozen Shoulder.

Frozen Shoulder mr arthrographic findings
Radiology, 2004Co-Authors: Bernard Mengiardi, Christian W. A. Pfirrmann, Christian Gerber, Jürg Hodler, Marco ZanettiAbstract:PURPOSE: To evaluate the magnetic resonance (MR) arthrographic findings in patients with Frozen Shoulder. MATERIALS AND METHODS: Preoperative MR arthrograms of 22 patients (six women, 16 men; mean age, 54.7 years) with Frozen Shoulder treated with arthroscopic capsulotomy were compared with arthrograms of 22 age- and sex-matched control subjects without Frozen Shoulder. The thickness of the coracohumeral ligament (CHL) and the joint capsule, as well as the volume of the axillary recess, were measured (Mann-Whitney test). Abnormalities in the CHL, subcoracoid fat, superior glenohumeral ligament, superior border of the subscapularis tendon, long biceps tendon, and subscapularis recess were analyzed in consensus by two blinded radiologists (χ2 test). RESULTS: Patients with Frozen Shoulder had a significantly thickened CHL (4.1 mm vs 2.7 mm in controls) and a thickened joint capsule in the rotator cuff interval (7.1 mm vs 4.5 mm; P < .001 for both comparisons, Mann-Whitney test) but not in the axillary recess...

Abnormalities in the CHL, subcoracoid fat, superior glenohumeral ligament, superior border of the subscapularis tendon, long biceps tendon, and subscapularis recess were analyzed in consensus by two blinded radiologists (chi(2) test). Patients with Frozen Shoulder had a significantly thickened CHL (4.1 mm vs 2.7 mm in controls) and a thickened joint capsule in the rotator cuff interval (7.1 mm vs 4.5 mm; P < .001 for both comparisons, Mann-Whitney test) but not in the axillary recess. The volume of the axillary recess was significantly smaller in patients with Frozen Shoulder than in control subjects (P = .03, Mann-Whitney test). Thickening of the CHL to 4 mm or more had a specificity of 95% and a sensitivity of 59% for diagnosis of Frozen Shoulder. Thickening of the capsule in the rotator cuff interval to 7 mm or more had a specificity of 86% and a sensitivity of 64%. Synovitis-like abnormalities at the superior border of the subscapularis tendon were significantly more common in patients with Frozen Shoulder than in control subjects (P = .014, chi(2) test). Complete obliteration of the fat triangle between the CHL and the coracoid process (subcoracoid triangle sign) was specific (100%) but not sensitive (32%). Thickening of the CHL and the joint capsule in the rotator cuff interval, as well as the subcoracoid triangle sign, are characteristic MR arthrographic findings in Frozen Shoulder.
