Bone-grafting enables restoration of the glenoid, but outcomes of this procedure may be hampered by early instability, which can lead to implant malpositioning, and by graft resorption, which can lead to implant loosening^2-7. To combat these potential complications, we utilize multiple bioresorbable pinning (MBP) during the bone-grafting process, in which as many bioresorbable pins as required are inserted from whatever aspect of the graft is appropriate until initial stability of the graft is achieved¹. We retrospectively compared the various grafting techniques applied for various degrees of retroversion, concluding that MBP is better when retroversion is >30°¹. Treatment decisions are made according to the degree of preoperative retroversion. The MBS technique is indicated for type-2 and type-3 glenoid deformities. This technique is not only relatively safe-as it involves only the use of bioresorbable materials-but also yields improved graft incorporation and less glenoid loosening¹.</p><p><strong>Description: </strong>This procedure is performed with the patient under general anesthesia and in the beach-chair position, via a deltopectoral approach. After placing the structural graft, 5 to 10 provisional 1.5-mm Kirschner wires are inserted through the graft up the medal cortical bone of the scapula. The Kirschner wires are subsequently replaced with bioresorbable (BR) pins (1.5-mm Fixsorb Pin; TEIJIN). If more wires are needed, another set of 4 to 5 RB pins is inserted to gain initial stability. After placing the graft, the glenoid component is implanted as usual.</p><p><strong>Alternatives: </strong>Traditionally, 1 or 2 screws are inserted in the periphery of the graft to obtain stability. The screws either must be inserted at an angle that does not impede placement of the implant² or are removed before the placement of the glenoid implant. One or a maximum of 2 long screws are inserted through the graft and glenoid³, meaning that the screw(s) must be aimed at a very narrow space between the central post and screws. Otherwise, these screws will represent an obstacle to the placement of the glenoid implant.</p><p><strong>Rationale: </strong>In addition to facilitating initial graft stability, this procedure promotes graft incorporation. Typically, when performing this procedure, a total of 15 to 20 temporary Kirschner wires are placed in sets, with 5 to 7 wires per set. Of these, the most stable wires, usually 8 to 10 in total, are replaced by BR pins. The resultant bone holes, whether filled or unfilled with the BR pins, may promote neovascularization and osteoinduction, enabling long-lasting remodeling of and improved incorporation of the bone graft.</p><p><strong>Expected outcomes: </strong>A prior study compared the use of MBP versus angulated bony-increased offset (BIO) graft, a","PeriodicalId":44676,"journal":{"name":"JBJS Essential Surgical Techniques","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/81/45/jxt-12-e21.00052.PMC9889295.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10665993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with a standard Bristow-Latarjet procedure, the key feature of this technique was that the coracoid process was placed into a trough (5 to 10 mm deep) in the glenoid neck, which substantially increased the bone contact area between the graft and glenoid neck.

Additionally, either an anterior or posterior synovectomy may be performed when the TGCT is limited to 1 compartment of the knee.

The anterior approach is performed via anteromedial parapatellar arthrotomy, with care to preserve the meniscal attachments and ligaments.

Briefly, following induction of general endotracheal anesthesia, a standard right- or left-sided Smith-Robinson incision is made. Discectomies are performed at the involved levels. By measuring the thickness of the OPLL on an axial preoperative computed tomography scan at each compressed level, the amount of each anterior vertebral body to be resected can be calculated preoperatively. This was, in general, equal to the thickness of the ossified mass at the same level. The previously calculated portion of each involved body in the vertebral body-OPLL complex is resected. Following the creation of a contralateral longitudinal osseous trough, the prebent anterior cervical plate is then placed, and the screws are installed after proper drilling and taping on the remaining vertebral bodies. The screws utilized in this procedure should not be too short to achieve adequate purchase in the vertebral body. Subsequently, the intervertebral cages are inserted. Thus, the vertebral body-OPLL complex is temporarily stabilized for the next procedure. Next, an ipsilateral longitudinal osseous trough is created to completely isolate the vertebral body-OPLL complex. Notably, the objective of complete isolation of the vertebral body-OPLL complex is to further anteriorly hoist the complex to decompress the spinal cord. Finally, screws are inserted through the plate and into each vertebral body and are gradually tightened to displace the bodies anteriorly.

Traditional surgical interventions have included anterior cervical corpectomy and fusion (ACCF), posterior laminoplasty, and laminectomy^2,3.

In addition, the clinical benefits of ACCF will be limited when the OPLL extends over >3 levels. Posterior decompression can achieve indirect decompression by allowing the spinal cord to float away from the ossified mass. This technique depends largely on the preoperative presence of cervical lordosis and is contraindicated in patients with kyphosis or severe OPLL.
