Full-thickness rotator cuff tears tend to increase in size in about half of patients aged 60 years or younger. Surgery should be initially considered in these patients to prevent a probable increase in size tear. Patients treated nonoperatively should be routinely monitored for tear size increase, especially if they remain symptomatic.

Despite a higher rate of complications than in the general population, the overall outcome of spine surgery in patients with mild to moderate Parkinson disease is good, with improvement of spine-related pain. A larger prospective study is warranted.

Study DesignRetrospective radiological review and analysis of 79 patients who underwent primary anterior cervical discectomy and fusion (ACDF) of 2 or 3 levels between 2011 and 2013.PurposeThis study aimed to determine the effect of the local placement of a steroid-soaked gelatin sponge after ACDF on prevertebral soft tissue swelling. Overview of LiteratureAlthough ACDF has become a popular choice for cervical fusion, the surgical involvement of the delicate anatomy of the neck frequently results in tissue irritation and edema. Swelling of the prevertebral soft tissue may consequently lead to mild-to-severe complications, ranging from dysphonia to dyspnea.MethodsOut of the 79 patients who underwent primary ACDF, 52 received a gelatin sponge soaked with 40 mg of Depo-Medrol placed adjacent to the operated cervical levels. Prevertebral soft tissue swelling was detected using postoperative lateral X-ray. The radiographic values were compared to those of 27 patients who did not receive the treatment.ResultsSoft tissue swelling was markedly decreased in patients who received the placement of the steroid-soaked gelatin sponge next to their fused levels after surgery compared with that in patients who did not receive it. No complications were documented with the use of steroids.ConclusionsThe placement of a steroid-soaked gelatin sponge markedly reduces postoperative soft tissue swelling following 2- or 3-level primary ACDF.

In the past few years, stem cells have become the focus of research by regenerative medicine professionals and tissue engineers. Embryonic stem cells, although capable of differentiating into cell lineages of all three germ layers, are limited in their utilization due to ethical issues. In contrast, the autologous harvest and subsequent transplantation of adult stem cells from bone marrow, adipose tissue or blood have been experimentally utilized in the treatment of a wide variety of diseases ranging from myocardial infarction to Alzheimer's disease. The physiologic consequences of stem cell transplantation and its impact on functional recovery have been studied in countless animal models and select clinical trials. Unfortunately, the bench to bedside translation of this research has been slow. Nonetheless, stem cell therapy has received the attention of spinal surgeons due to its potential benefits in the treatment of neural damage, muscle trauma, disk degeneration and its potential contribution to bone fusion.

Spinal subdural hematoma (SSDH) following spine surgery is an extremely rare condition, with only three cases being reported in the literature. Unintended durotomy has been associated with SSDH due to alterations of pressures in the dural compartments. The objective of the present report was to report two rare cases of acute SSDH developed after lumbar decompressive surgery. In one of the patients, the diagnosis of SSDH was followed by urgent hematoma evacuation via durotomy due to the patient's worsening neurological symptoms. In the second patient, the SSDH was treated conservatively due to the absence of severe or progressive motor or sensory deficits. In conclusion, emergency evacuation via durotomy is the treatment of choice for patients with SSDH and neurologic impairment. Conservative management may be indicated in selected cases with absent motor and sensory deficits.

AIMTo review cases of emergent reintubation after cervical surgery.METHODSPatients who were emergently intubated in the post-operative period following cervical surgery were identified. The patients’ prospectively documented demographic parameters, medical history and clinical symptoms were ascertained. Pre-operative radiographs were examined for the extent of their pathology. The details of the operative procedure were discerned.RESULTSEight hundred and eighty patients received anterior- or combined anterior-posterior cervical surgery from 2008-2013. Nine patients (1.02%) required emergent reintubation. The interval between extubation to reintubation was 6.2 h [1-12]. Patients were kept intubated after reintubation for 2.3 d [2-3]. Seven patients displayed moderate postoperative edema. One patient was diagnosed with a compressive hematoma which was subsequently evacuated in the OR. Another patient was diagnosed with a pulmonary effusion and treated with diuretics. One patient received a late debridement for an infected hematoma. Six patients reported residual symptoms and three patients made a complete recovery.CONCLUSIONRespiratory compromise is a rare but potentially life threatening complication following cervical surgery. Patients at increased risk should be monitored closely for extended periods of time post-operatively. If the airway is restored adequately in a timely manner through emergent re-intubation, the outcome of the patients is generally favorable.
