RESUMEN
PURPOSE: To evaluate clinical features and the effect of parathyroid hormone (PTH) on treatment outcomes of patients with pelvic insufficiency fractures. MATERIALS AND METHODS: Fifteen patients diagnosed with pelvic insufficiency fractures were evaluated retrospectively. All patients had osteoporosis with mean lumbar T score of -3.9 (range, -3.1 to -6.4) and the mean age was 76.5 years. In all cases, simple radiography and computed tomography was used for final diagnosis; additional magnetic resonance imaging and technetium bone scans were used to confirm the diagnosis in 2 and 6 patients, respectively. Initial conservative treatment was used in all cases; treatment with PTH was applied in 5 cases. Radiological follow-up was done every 4 weeks up to 6 months and every 3 months thereafter. Symptom improvement was measured using visual analogue scale (VAS) score. RESULTS: Fractures were located: i) sacrum and pubis (9 cases), ii) isolated sacrum (4 cases) and iii) isolated pubis (2 cases). One case showed fracture displacement and pain aggravation at 4 week follow-up which was treated with percutaneous sacro-iliac fixation using cannulated screws. Duration of bone union was significantly shorter in the patients who used PTH (P<0.05). VAS scores were also lower in the group treated with PTH; however, statistical significance was not reached. CONCLUSION: In patients with osteoporosis, a pelvic insufficiency fracture should be considered if pain is experienced in the pelvic area in the absence of major trauma. While nonoperatic has been shown to be sufficient for treatment, our study shows that PTH therapy shortens treatment period and could be a favorable treatment option.
RESUMEN
During arthroscopic procedures, leakage of irrigation fluid into surrounding tissue planes is a frequently noticed phenomenon usually clinically asymptomatic and resolving within 12 hours postoperatively. Although rare, this fluid may produce life-threatening complications such as airway compromise. This article describes a case of upper airway obstruction in a 60-year-old man undergoing arthroscopic repair for an atrophic rotator cuff tear. The patient presented with a 6-month history of pain and weakness in the left shoulder. Magnetic resonance imaging studies revealed a massive rotator cuff tear with significant retraction and fatty degeneration of cuff musculature. Perioperatively, all vital cardiorespiratory parameters were within normal limits. Postoperatively, immediately on extubation, he was dyspneic, and examination revealed a diffuse swelling extending from the left shoulder up to the neck and face. He was reintubated and sent to the recovery room, where he recovered 12 hours later. This article highlights the possibility of respiratory compromise due to the extravasation of irrigation fluid into the neck and chest during arthroscopic repair of massive and atrophied cuff tears, even with shorter surgical time as is this case. The widened suprascapular space will offer less resistance to the spread of fluid into the neck and chest from the shoulder. We advocate monitoring the patient continuously to prevent this serious complication from becoming life-threatening.
