AI Article Synopsis
- Sinking skin syndrome (SSS) is a complication following decompressive craniectomy (DC) that is not well understood, with a study showing that about 63% of the 27 patients analyzed experienced SSS.
- The majority of patients were treated for traumatic brain injuries, with those developing SSS having larger DC diameters and specific flap shapes like "sunken" and "extracranial herniation."
- Low volumes of the third ventricle were linked to SSS, and nearly all patients showed improvement after the cranial defect was surgically repaired.
Article Abstract
Background: The sinking skin syndrome (SSS) is a particular complication after a decompressive craniectomy (DC). It still remains a poorly understood and underestimated entity.
Methods: Retrospective case series of craniectomized patients with and without SSS. Clinical and radiological features (DC diameter, shape of craniectomy flap, and midline deviation) were described and relative volumes of intracranial loss were quantified.
Results: Twenty-seven patients (63% with SSS). The most common indication for DC was traumatic brain injury: 48.15%. The p50 diameter of DC was 12.8 cm for patients with SSS and 11.1 cm for patients without (Z score = 0.32). DC area was 81.5 cm for patients with SSS and 71.43 cm for patients without the syndrome (Z score = 0.61). According to the shape of the craniectomy flap, we classified our patients as: «same level» (51.8%), «sunken» (25.9%), and «extracranial herniation» (14.8%). Two patients (7.4%) had paradoxical herniation. Midline deviation was present in 12 (70.6%) patients with SSS. The 3 ventricle volume average was 1.2 cc for patients with SSS versus 2.35 cc for patients without (Z score = 0.04). About 94.11% of patients (16 out of 17) clearly improved after replacement of the cranial defect.
Conclusion: In our series, low 3 ventricle volumes had a good relation with SSS. The presence of a sunken flap does not guarantee SSS and we propose the following radiologic description: A = sunken, B = same level, C = extracranial herniation, and D = paradoxical. Replacement of the skull defect is the main treatment.

January 2025
American Hip Institute Research Foundation, Chicago, IL 60018. Electronic address:
Purpose: To identify sex-based differences in pathology, outcomes, and complications after hip arthroscopy for femoroacetabular impingement (FAI), and to compare patient-reported outcomes (PRO) scores between males and females.
Methods: The PubMed and MEDLINE databases were searched in September 2024, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Included studies had data stratified by sex, minimum 2-year patient reported outcome (PRO) scores for hip arthroscopy in the setting of FAI and labral pathology, and a 2014 or later publication date.
Application of additive manufacturing TaBw01 porous tantalum rod in ARCO stage II osteonecrosis of the femoral head.

Center for Joint Surgery, Southwest Hospital, Army Medical University, Gaotanyan Street, Shapingba District, Chongqing, 400038, China.
Purpose: This study aims to investigate the suitable surgical strategies for applying TaBw01 porous tantalum rod across different stages of osteonecrosis of the femoral head (ONFH).
Methods: TaBw01 tantalum rods were fabricated using type FTaY-1 tantalum powder via the foam impregnation-sintering method. Mechanical testing with the Instron 8801 universal testing machine and finite element analysis (FEA) assessed single tantalum rod implantation and impaction bone grafting combined with rod implantation.

Background: A growing body of evidence explored symptom burden of somatic symptom disorder (SSD) and its complex etiology involving psychosocial aspects. Child abuse has been linked to numerous psychopathologies including somatic symptoms as well as impaired personality functioning and disruptions in epistemic trust. This work aims to investigate personality functioning and epistemic trust in the association between child abuse and somatic symptom burden.

Background: Aneurysmal subarachnoid hemorrhage (aSAH) carries a high economic cost and clinical morbidity in the United States. Beyond prolonged admissions and poor post-injury functional status, there is an additional cost of chronic shunt-dependent hydrocephalus for many aSAH patients. Adjuvant lumbar drain (LD) placement has been hypothesized to promote clearance of subarachnoid blood from the cisternal space, with an ultimate effect of decreasing shunt placement rates.
