Pectoralis major tendon transfer for recurrent anterior shoulder dislocation after primary surgery in an elderly patient: A case report.

RATIONALE: Adequate stability of traumatic anterior shoulder dislocation without any obvious damage to the anterior capsulolabral structure in elderly patients can be achieved by treating the associated rotator cuff injuries. However, in case of recurrent shoulder dislocation despite rotator cuff repair, the repaired rotator cuff may be weakened or reruptured and is often impossible to repair again. Therefore, the role of the rotator cuff as a shoulder stabilizer cannot be expected. Even if the anterior joint capsule is left, it is too weak to imbrication either. An additional anterior structural reconstruction that can replace the rotator cuff and capsule is needed to prevent recurrence. PATIENT CONCERNS: A 59-year-old man visited our clinic because of traumatic anterior dislocation of the right shoulder combined with anterior-superior rotator cuff tear. Because there was no obvious anterior capsulolabral injury, he underwent arthroscopic rotator cuff repair only. Postoperative rehabilitation was maintained; however, anterior shoulder dislocation recurred 10 months postoperatively. DIAGNOSIS: Physical examination revealed anterior instability in abduction and external rotation of the shoulder joint. Magnetic resonance imaging suggested retear of the repaired anterior-superior rotator cuff and Hill-Sachs lesion of the humeral head. INTERVENTIONS: Diagnostic arthroscopy was performed. The reruptured rotator cuff seemed impossible to repair; thus, arthroscopic remplissage procedure was performed for engaging the Hill-Sachs lesion. In addition, open pectoralis major tendon transfer for anterior stabilization was performed via the deltopectoral approach. OUTCOMES: At the 12-month follow-up, the patient showed good clinical outcomes, including internal rotation of the shoulder joint without recurrent instability. LESSON: Recurrent anterior shoulder dislocation after primary surgery in the elderly may be a challenging situation for surgeons. In patients with irreparable anterior rotator cuff tear and for whom reconstruction of the anterior glenoid is not indicated, pectoralis major tendon transfer is a good treatment option for satisfactory clinical outcomes without recurrence.

Radiologic outcomes of open reduction and internal fixation for cementless stems in Vancouver B2 periprosthetic fractures.

OBJECTIVE: The aim of this study was to evaluate the radiologic outcomes of open reduction and lateral plating with wiring in the treatment of Vancouver B2 periprosthetic femoral fractures. METHODS: We retrospectively recruited 37 patients treated with ORIF with lateral plating and wiring for Vancouver B2 fractures. The 27 patients (15 men and 12 women; mean age: 70.8 ± 8.3 years) without follow-up loss had achieved complete bony union without notable complications. The average union period was checked after operation with radiologic findings. Radiologic outcomes were evaluated by ipsilateral limb length discrepancy (LLD) and subsidence between immediate postoperative length and length at postoperative 1 year after adjusting for magnification differences. The average distance to which the retained stem sunk down was investigated between immediate postoperative radiographs and final radiographs showing union. RESULTS: Ten patients could not be evaluated, because of mortality or failure to follow up. The average time to union was 18.3 weeks, and the average distance of stem sinking was 2.5 ± 1.7 mm (range: 0-7.2 mm), which was significantly different between immediate postoperative radiographs and final radiographs. There was no case with loss of reduction or loss of fixation, requiring revision surgery. CONCLUSION: Open reduction and lateral plating with wiring as a treatment for Vancouver B2 periprosthetic femoral fractures produced good radiologic outcomes with successful bony union. ORIF can be considered the alternative option for treating patients with Vancouver B2 PPF, instead of stem revision surgery. LEVEL OF EVIDENCE: Level IV, Therapeutic study.

Amputation of multiple limbs caused by use of inotropics: Case report, a report of 4 cases.

RATIONALE: We present 4 cases of symmetrical peripheral gangrene (SPG) associated with use of inotropic agent to elevate blood pressure. SPG is a relatively rare phenomenon characterized by symmetrical distal ischemic damage that leads to gangrene of 2 or more sites in the absence of large blood vessel obstruction, where vasoconstriction rather than thrombosis is implicated as the underlying pathophysiology. We present 4 SPG cases of the multiple limbs amputation, associated with inevitable use of inotropic agents. PATIENT CONCERNS: Inotropic agents including dopamine and norepinephrine are used frequently in the treatment of hypotension, and its effectiveness in treating shock is firmly established. However, it can be caused peripheral gangrene by prolonged administration of high dose inotropics, inducing the constant contraction of the peripheral blood vessels. DIAGNOSIS: These 4 patients had different clinical histories and background factors, but each experienced sepsis. The level of amputation is determined by the line of demarcation in concert with considerations of the biomechanics of stump stability, weight bearing, and ambulation. INTERVENTIONS: After recovering of general conditions and completion of demarcation, these 4 patients underwent the amputation of multiple limbs.(bilateral amputations of upper extremities or bilateral amputations of lower extremities). OUTCOMES: In each patient, there was no additional amputation caused by extension of SPG, and the rehabilitation with appropriate orthosis was performed. Treatment of underlying disease were continued too. LESSONS: It is important to alert the possibility of amputations, according to the use of inevitable inotropics. We recommended the careful use of the inotropic agents to the physicians in treating septic shock.

Physeal fracture in the wrist and hand due to stress injury in a child climber: A case report.

RATIONALE: In competitive athletes, the upper extremity is subject to tremendous torsional forces with axial loading due to repetitive weight bearing. Approximately 25% of injuries in sports are related to the hand or wrist. Skeletal deformity on the wrist physis is common in athletes due to repetitive loading and presents at early ages between 6 and 13 years. Additionally, it is more common in female than in male athletes. PATIENT CONCERNS: An 11-year-old girl who was a climber complained of pain on her left wrist without direct trauma. She had participated in climbing exercise for several years and had no medical history. Thorough radiological evaluation, we diagnosed physeal injury of the left radius. After healing of the physeal injury of the radius, she complained of pain on fourth finger of right hand and radiographs revealed physeal injury of the right fourth finger. DIAGNOSIS: Radiographs revealed physeal injury of the left radius. Magnetic resonance imaging revealed epiphyseal widening of the radial aspect of the wrist and bone marrow signal increase on T2-weighted imaging. Likewise, radiographs showed physeal injury of the right fourth finger INTERVENTIONS:: No surgery was performed and we applied wrist brace and finger splint for conservative treatment. OUTCOMES: The patient's pain was immediately relieved. The patient had no complications or recurrence of symptoms and was undergoing regular check-ups every 6 months. LESSONS: During climbing exercise, repeated high pressure causes damage of the hand and wrist joints in young patients. Chronic pain in this group must be carefully evaluated, and radiographs should be obtained for diagnosis and early treatment. Conservative treatment of these injuries has good results, and avoiding intensive power training avoids the risk of this injury.

Posterior shoulder dislocation with ipsilateral proximal humerus type 2 physeal fracture: case report.

In pediatric patients, proximal humeral physeal fractures are uncommon injuries compared with distal physeal fractures. Usually, the growth plate is the most vulnerable site of fracture in the proximal humerus. Proximal humeral physeal fractures accompanying posterior shoulder dislocation are very rare. There are few recent reports on the combination of glenohumeral dislocation and proximal humerus fractures. Here, we describe a case of posterior shoulder dislocation with ipsilateral proximal humerus type 2 physeal fracture in a 9-year-old boy. We treated the patient by closed reduction and percutaneous pinning under general anesthesia.

Clinical and Radiologic Outcomes among Bipolar Hemiarthroplasty, Compression Hip Screw and Proximal Femur Nail Antirotation in Treating Comminuted Intertrochanteric Fractures.

PURPOSE: In comminuted intertrochanteric fractures, various operative options have been introduced. The purpose of this study was to determine whether there were differences in clinical and radiologic outcomes among bipolar hemiarthroplasty (BH), compression hip screw (CHS) and proximal femur nail antirotation (PFNA) in treating comminuted intertrochanteric fractures (AO/OTA classification, A2 [22, 23]). MATERIALS AND METHODS: We retrospectively evaluated total 150 patients (BH, 50; CHS, 50; PFNA, 50) who were operated due to intertrochanteric fractures from March 2010 to December 2012 and were older than 65 years at the time of surgery. We compared these three groups for radiologic and clinical outcomes at 12 months postoperatively, including Harris Hip Score, mobility (Koval stage), visual analogue scale and radiologic limb length discrepancy (shortening). RESULTS: There was no statistical significance among three groups in clinical outcomes including Harris Hip Score, mobility (Koval stage), visual analogue scale. However, there was significant differences in radiologic limb discrepancy in plain radiographs at 12 months postoperatively (radiologic shortening: BH, 2.3 mm; CHS, 5.1 mm; PFNA, 3.0 mm; P=0.000). CONCLUSION: There were no clinical differences among BH, PFNA, and CHS in this study. However, notable limb length shortening could be originated during fracture healing in osteosynthesis, compared to arthroplasty (BH
