Long-Lever-Arm Manipulation Under Anesthesia With Resultant Traumatic Anterior Shoulder Dislocation.

The patient was a 61-year-old woman who underwent long-lever manipulation under anesthesia (MUA) for adhesive capsulitis. Two weeks following MUA, the constellation of clinical findings raised concern for possible adverse outcomes. Radiographs were obtained, as well as subsequent magnetic resonance imaging and computed tomography scans. Images revealed anterior shoulder dislocation with Bankart and Hill-Sachs lesions, and an anterior rotator cuff tear. J Orthop Sports Phys Ther 2016;46(8):707. doi:10.2519/jospt.2016.0412.

A noninvasive mechanical treatment to reduce the visible appearance of cellulite.

Cellulite is a cosmetic condition of subcutaneous fat herniation through fibrous connective tissue that results in a dimpled appearance of the skin. Occurring in approximately 85% to 90% of all women worldwide, cellulite has been well studied. The result has been the development of a plethora of treatment protocols yielding little to no success. We describe a noninvasive mechanical treatment for women with cellulite, evaluating the safety and effectiveness of a technique that utilizes a unique patented device for the reduction of the visible appearance of cellulite.

Proximal row carpectomy with capitate resection and capsular interposition for treatment of scapholunate advanced collapse.

Proximal row carpectomy with capitate head resection and dorsal capsular interposition was performed in 8 patients with stage II and III scapholunate advanced collapse (SLAC). Mean patient age was 58.5 years (range, 50-79 years). One year postoperatively, range of motion and grip strength were not significantly changed from preoperative values. Mean postoperative Disabilities of the Arm, Shoulder, and Hand questionnaire score was 27. Pain improved from 8.8 preoperatively to 4.3 postoperatively on a scale of 0-10. Pain levels were highly inversely correlated with final range of motion (r=-0.94, P=.0004). Proximal row carpectomy with capitate leveling and capsular interposition for stage II and III SLAC wrist provides reasonable pain relief in 75% of patients. Patients should be counseled that 25% of cases may demonstrate progression of radiocapitate degeneration, necessitating further intervention.

Microvascular supply of the lateral epicondyle and common extensor origin.

Lateral epicondylitis is a common condition affecting 1% to 3% of the population. Although the exact cause is still unknown, numerous theories have been put forth. One theory suggests a hypovascular zone at the origin of the common extensor mass. This study examines the microvascular supply of the lateral epicondyle and the common extensor mass, with the use of India ink injection and the Spalteholz tissue-clearing technique. Six fresh-frozen cadaveric arms underwent serial sectioning (coronal plane in five and axial plane in one) after vascular injection with India ink. Sections were cleared via a modified Spalteholz technique. Photographs were taken before and after the clearing procedure, and the microvascular pattern of the common extensor mass and lateral epicondyle was described. Two hypovascular zones were identified in the region of the lateral epicondyle. The first was noted at the proximal lateral epicondyle just distal to the supracondylar ridge and the second 2 to 3 cm distal to the lateral epicondyle on the deep surface of the common extensor tendon. Two regions of hypovascularity were noted at the lateral epicondyle and within the common extensor origin. These hypovascular regions may preclude the normal inflammatory cascade and healing response to microtearing in this region. Thus, these zones may play a role in the etiology of lateral epicondylitis.

Surgical correction of dorsally angulated distal radius malunions with fixed angle volar plating: a case series.

PURPOSE: To report our experience using a fixed-angle volar plate in conjunction with a corrective osteotomy and cancellous bone graft for the treatment of distal radius malunions with dorsal angulation in 4 patients. METHODS: Four consecutive patients had a volarly based opening wedge osteotomy with a fixed angle volar plate and cancellous bone grafting for the treatment of a dorsally angulated distal radius malunion. Data collected retrospectively included a visual analog pain scale, grip strength, range of motion, radiographic parameters, and each patient's subjective functional outcomes as measured by the Disabilities of the Arm, Shoulder, and Hand questionnaire. Motion, strength, and radiographic values were compared with the contralateral arm for each patient. RESULTS: The average time from initial fracture to corrective osteotomy was 346 days. The average length of follow-up evaluation was 13.5 months. The flexion-extension arc of motion increased an average of 21 degrees to a value of 84% of the contralateral side; the pronation-supination arc of motion increased an average of 20 degrees to a value of 98% of the contralateral side. The average tilt of the radius improved from 26 degrees extension to 2 degrees extension; the average radial inclination improved from 22 degrees to 24 degrees; the average ulnar variance excluding the 1 patient who had a distal ulna resection improved from 5 mm to 1 mm. The average retrospective Disabilities of the Arm, Shoulder, and Hand score improved from 30 to 7; the average retrospective visual analog pain scale score improved from 4.5 to 1. The average grip strength increased from 20 to 29 kg, which corresponded to 73% of the contralateral extremity. CONCLUSIONS: The rigid characteristics of fixed angle volar plates can provide an alternative to the traditional techniques of distal radius osteotomy including structural bone grafting and dorsal plate fixation or external fixation. In addition these plates are strong enough to allow for early postoperative motion. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.

The effect of an extended flexor carpi radialis approach on blood flow to the distal radius: a cadaveric study.

The effect of an extended flexor carpi radialis approach on the blood supply of the radius was examined in six (3 paired) fresh frozen cadaver limbs after injection with India ink and clearing using a modified Spalteholz technique. An extended flexor carpi radialis approach to the distal radius was made in the left limb in each of the three-paired limbs. The right limb served as a nonoperative control. Following perfusion of the arterial vasculature of each limb with India ink, serial transverse sections were cut and the intraosseous blood supply evaluated using a modified Spalteholz technique. Both controls and surgical specimens demonstrated complete cortical penetration from endosteal vessels in the proximal and midsections of the radius. In the distal radius, surgical specimens demonstrated reduced perfusion volarly, however there continued to be perfusion of ink through intact dorsal and ulnar metaphyseal perforating arteries. Persistent vascular perfusion to the distal radius remains through intact endosteal vessels and metaphyseal perforators of extensive surgical soft-tissue stripping.

Nerve decompression for complex regional pain syndrome type II following upper extremity surgery.

PURPOSE: To evaluate the results of nerve decompression for the symptoms of complex regional pain syndrome that developed after upper-extremity surgery. METHODS: Eight patients (5 men, 3 women) developed worsening severe pain, swelling, and loss of range of motion after an upper-extremity surgery. The diagnosis of complex regional pain syndrome was made at an average of 6 weeks (range, 1-10 weeks) after the surgical procedure. A clinical diagnosis of either median or combined median and ulnar nerve compression at the wrist was confirmed in all patients with electrophysiologic testing. Nerve decompression was performed at a mean of 13 weeks after the procedure. Subjective (Disabilities of the Arm, Shoulder, and Hand questionnaire; visual analog pain scale) and objective (forearm, wrist, and finger range of motion; grip strength) data from before and after nerve decompression were reviewed. RESULTS: The average score on the Disabilities of the Arm, Shoulder, and Hand questionnaire decreased from 71 to 30 (p < .05). The mean visual analog pain score decreased from 7.5 to 1.8. (p < .05) There was immediate and near-complete resolution of all somatic complaints including hypersensitivity to touch, hyperhydrosis, swelling, and cold sensitivity. Range of motion and grip strength improved. CONCLUSIONS: Traditionally surgical treatment has been avoided in patients with complex regional pain syndrome; however, in the setting of clinical and electrophysiologic evidence of nerve compression surgical intervention may hasten recovery in these patients.

Predicting shoulder strength using allometry: implications for shoulder outcome assessments.

INTRODUCTION: Shoulder strength is an integral component of shoulder function. In assessing shoulder function many functional scales rely on direct or indirect measures of strength. Strength, and thus these scales, is often highly correlated with age. We propose an allometric method for assessing shoulder strength. Allometric modeling has provided accurate predictions of biologic growth and physiologic function in both human and animal studies. Allometry utilizes the relationship between the two homologous structures on the left and right sides of the body, providing in effect an internal control and thus eliminating many confounding effects, e.g. age and level of activity. METHODS: Twenty patients with unilateral shoulder dysfunction underwent strength testing of their affected and unaffected shoulder. Strength testing of the bilateral shoulders was also assessed in twenty people without shoulder pain in order to delineate the effect of hand dominance on strength in those without shoulder pain. Absolute and predicted strength deficits of the involved shoulder were calculated via regression analysis. Pearson's correlation coefficients were computed between age and strength. RESULTS: Utilizing the contralateral extremity as an internal control eliminates age as a confounding variable in predicting strength outcomes (r = 0.093). CONCLUSION: Allometric concepts, applied to shoulder strength assessment, eliminates age as a confounding variable. Strength testing of both shoulders should be considered in the development of future shoulder outcome scales in order to eliminate the strong influence of age.

Theory and technique of translational manipulation for adhesive capsulitis.

Manipulation of the glenohumeral joint with the patient under anesthesia has long been used as a treatment modality for refractory shoulder stiffness. Recently, translational manipulation of the glenohumeral joint under interscalene brachial plexus regional block has been shown to be efficacious in the treatment of adhesive capsulitis and to present a low risk of iatrogenic injury. The theory and technique of glenohumeral translational manipulation for the treatment of adhesive capsulitis are presented here.
