Clinical case of successful operative treatment of congenital kyphosis is reported. Deformation was caused by multiple lower thoracic and lumbar vertebral body abnormalities. Associated spinal abnormalities were outspread absence of laminae, hydromyelia, and diastematomyelia. Preoperative computed tomography analysis revealed absence of instrumentable bony structures within malformed lower thoracic and lumbar spine. As instrumented fusion procedure was technically impossible anterior fusion without internal fixation was performed. Autogenous rib was used as a bone graft. Bone graft was extende

A damaged interphalangeal (IP) joint may be treated by fusion. Arthrodesis should leave the joint at the most functional angle and give sound bony union in the shortest possible time, maintaining maximum proximal and distal joint motion. The lateral oblique placement of a single AO lag screw, proximal to distal, achieves these aims. This method gives sufficient proximal bone for screw purchase and better control of the desired angle of fusion. This technique has led to fusion in 22 of 23 joints (96%), taking an average of 8.2 weeks.

Objective: To present a rare case of congenital maxillomandibular fusion or syngnathia.
 Methods: 
 Study Design: Case report
 Setting: Tertiary Private Teaching Hospital
 Patient: One
 Results: A 3-year-old girl with oral adhesion (syngnathia) caused by a mandibular to maxillary fibrous band underwent successful surgical division of maxillomandibular bony fusion. Subsequent monitoring and serial oral dilations were performed post operatively, resulting in mouth opening of 24mm over a period of 3 months. Currently, the patient is able to tolerate a general liquid diet.

ABSTRACT Objectives: To establish a rat model of a one-piece mandible using the principles of gingivoperiosteoplasty and guided bone regeneration to fuse the midline symphyseal area. Material and Methods: Twenty-four Sprague-Dawley female rats were divided into two groups: 12 experimental and 12 control. Both groups were imaged using in vivo micro-computed tomography at baseline and at end point (5 months). The experimental group received regenerative surgery at the symphysis area; the control group received no treatment. Outcomes were evaluated by radiographic examination of gross and volumet

Objective: This study presents a technical note on Unilateral Biportal Endoscopic Transforaminal Lumbar Interbody Fusion (UBE-TLIF) using dual cages, focusing on its potential to enhance fusion rates and minimize cage subsidence. Background: TLIF is a well-established treatment for lumbar degenerative conditions, yet traditional and minimally invasive approaches are limited by narrow working corridors, reduced disc space visualization, and increased risk of pseudoarthrosis and subsidence. The biportal endoscopic approach offers superior visualization and decompression capabilities. Incorporati

BackgroundAnkle and hindfoot fusion in the presence of large bony defects represents a challenging problem. Treatment options include acute shortening and fusion or void filling with metal cages or structural allograft, which both have historically low union rates. Impaction grafting is an alternative option.MethodsA 2 centre retrospective review of consecutive series of 32 patients undergoing hindfoot fusions with impaction bone grafting of morselised femoral head allograft to fill large bony void defects was performed.

Twenty patients with severe neuropathic (Charcot) ankle deformities underwent 21 attempted ankle fusions with a retrograde locked intramedullary nail as an alternative to amputation. All had insensate heel pads and had failed at nonoperative methods of accommodative ambulatory bracing. In 11, the talus was either absent, or the deformity was of sufficient magnitude to require talectomy to align the calcaneus under the tibia for plantigrade weightbearing. Ages ranged from 28 to −68 (average 56.3) years. Nineteen were diabetic, 12 being insulin-dependent. Their average body weight was 102 kg, wi

Background: Low back pain as a result of degenerative disc disease (DDD) imparts a large socioeconomic impact on the health care system. Correct diagnosis and treatment of DDD is difficult and controversial. Whether inter-body fusion is the treatment of choice in DDD is still a dilemma. The Transforaminal interbody fusion (TLIF) developed by Harms is a modification of posterior lumbar interbody fusion(PLIF). Advantage of the TLIF over PLIF with lesser complications avoidance of epidural scarring, less intra-operative bleeding, and lesser chance of dural injury. Methods: We evaluated 30 patient

Background: Hangman’s fractures (HF) are defined by bilateral fractures of pars interarticularis of the axis. Most can be treated with a collar. However, the treatment strategies for atypical HF (AHF) involve the pedicles, are unstable, and require fusion. Here, we present three cases of AHF that failed anterior arthrodesis warranting repeat anterior (one case), and posterior fusions (three cases).

A variety of donor-site complications have been reported for anterior cervical discectomy and fusion (ACDF) using autologous iliac bone graft. To minimize such morbidities and to obtain optimal bony fusion at the ACDF surgery, a novel technique was used to harvest cancellous bone from the autologous clavicle instead of the popular iliac crest graft. After a routine cervical discectomy of the affected level, a 1.5-cm linear skin incision was made over the clavicle within 2.5 cm of the sternoclavicular joint on the medial one-third portion.
