En bloc resection and vascularized ulnar pedicle graft reconstruction with plate fixation for giant cell tumour of the distal radius

We retrospectively reviewed the medical records of ten patients (five men and five women) who were treated in our unit for Campanacci Grade III giant cell tumour of the distal radius between July 2017 and December 2019. Following en bloc resection of a giant cell tumour of the distal radius, the wrist was reconstructed by transposing a vascularized pedicle graft from the ipsilateral ulnar shaft. The graft was fixed to the radial shaft and proximal carpal row with plates. At a mean follow-up of 23.5 months (range 18 to 31), bony union was achieved in all cases and there were no tumour recurrences. All patients had a good range of pronation and supination, but flexion and extension of the wrist was limited. DASH scores ranged from 5 to 11. This reconstruction method is a safe and effective procedure that provides good aesthetic outcomes, removes the need for microvascular techniques and reduces donor site morbidity. Level of evidence: IV

Study of surgical outcome of mid third clavicle fractures surgically managed by locking compression plate

<p class="abstract">Clavicle is one of the most frequently fractured bones in young and active individuals. They account for 2.6-12% of all fractures and for 44-66% of fractures around the shoulder. Majority of clavicle fractures are mid shaft (80-85%). Functional outcome of midshaft fracture not only depends on the union but also on its length which has to be maintained. Thus a displaced or comminuted fracture carries a risk of symptomatic malunion, non-union or poor functional outcome with cosmetic deformity. The recent trend is shifting to internal fixation of these displaced mid shaft clavicle fracture. This was a prospective study of 20 cases of fresh mid third clavicle fracture admitted to MNR medical college and hospital from August 2020 to September 2021. Cases were taken according to inclusion and exclusion criteria. Medically unsuitable and patients not willing for surgery were excluded from the study. There were 17 male patients and 3 female patients with mid 1/3 closed clavicle fracture. 12 patients had right sided clavicle fracture and 8 patients had fracture of the left clavicle. All 20 fractures were closed fractures. Majority of the patients sustained fracture due to road traffic accident (high energy trauma) in 16 cases, fall from height in 3 cases and assault in one case. The mean duration to surgery from the day of presentation and injury was 2.1 days for middle third clavicle fractures. Functional outcome as assessed by constant and Murley scoring was favourable with excellent to good result in 97% cases and fair in 3% cases. The average constant score was 93.35 in one year follow up in middle third group. This study has some limitations. The conclusions drawn from this analysis cannot be generalized because of the small number of cases. In conclusion, for middle third clavicle fractures bony union could be achieved with locking compression plates and the clinical outcomes were satisfactory. All the fractures united and there were no cases of nonunion.</p>

Effect of lumbar lordosis angle in adolescent baseball players on the development of lumbar spondylolysis v1

Background: Lumbar spondylolysis is a stress fracture of the lumbar vertebral arch that occurs frequently in adolescents. Lumbar spondylolysis has a high prevalence in athletes, especially baseball players. When lumbar spondylolysis occurs, restriction of sports activities is inevitable until the bony union is achieved. Therefore, prevention of the onset of lumbar spondylolysis is necessary, and it is necessary to elucidate the risk factors that influence the onset of the disease. An increase in lumbar lordosis angle may influence the development of lumbar spondylolysis because the lumbar lordosis angle increases the compressive stress in the vertebral arch. However, there are no reports on the effect of lumbar lordosis angle and the development of lumbar spondylolysis in adolescent baseball players. Therefore, the purpose of this study was to investigate the effect of lumbar lordosis angle on the development of lumbar spondylolysis in adolescent baseball players. METHODS: Eligible patients were those who visited the orthopedic clinic from January 1, 2018, to October 31, 2021. The selection criteria were male baseball players aged 11-18 years who visited the clinic, and the exclusion criteria were those whose superior endplate of L1 and superior endplate of S1 could not be identified in the MRI images. The existence of development of lumbar spondylolysis, lumbar lordosis angle, age, and pitching experience of the above patients will be assessed based on electronic medical records and imaging findings. Statistical analysis was performed using logistic regression analysis, with the objective variable being the existence of lumbar spondylolysis and the explanatory variables being the lumbar lordosis angle, age, and previous pitching experience.Discussion: This study examines the effect of the lumbar lordosis angle on the development of lumbar spondylolysis in adolescent baseball players. An increase in lumbar lordosis angle may influence the development of lumbar spondylolysis and may be a risk factor for the development of lumbar spondylolysis.

Free Medial Femoral Condyle Flap for Reconstruction of Scaphoid Nonunion: A Systematic Review

Background The free medial femoral condyle (MFC) bone flap is an attractive option for reconstruction of scaphoid nonunion utilizing vascularized bone to augment bony healing, especially in cases of failed prior treatment or osteonecrosis. This review aims to determine the role and reliability of the free MFC flap for treatment of scaphoid nonunion. Methods A search of electronic databases was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Articles examining free MFC bone flaps for treatment of scaphoid nonunion were included for analysis. Outcomes of interest included flap failure, postoperative union rate, time to union, carpal indices, functional outcomes, and complications. Results Twelve articles met the inclusion criteria. A total of 262 patients underwent free MFC flaps for treatment of scaphoid nonunion. The most common site of nonunion was the proximal pole of the scaphoid with 47% of patients receiving prior attempts at operative management. Overall bony union rate was 93.4% with a mean time to union of 15.6 weeks. There were no flap failures reported. Improvements in carpal indices including scapholunate (p < 0.0004), radiolunate (p < 0.004), lateral interscaphoid angles (p < 0.035), and revised carpal ratio height (p < 0.024) were seen postoperatively. Visual analog scale improved postoperatively from 6.5 to 2.3 (p < 0.015). Postoperative complications were observed in 69 cases (26.3%), with 27 patients (10.3%) requiring further operative intervention. However, no major donor or recipient site morbidity was appreciated. Conclusion MFC flaps provide a highly versatile and reliable option for reconstruction of scaphoid nonunion with excellent bony union rates and acceptable complication rates. The present literature suggests that MFC reconstruction of scaphoid nonunion restores radiocarpal anatomy and improves wrist function without causing significant donor or recipient site morbidity.

Evaluation of functional outcome of metacarpal fractures managed by operative techniques: a hospital based study

Background: Metacarpal fractures comprise approximately 35.5% of cases in daily emergencies, mostly due to road traffic accidents, fall, and assault. The main goal of treatment is to achieve the strong bony union without any functional disability. Aim of the study was evaluation of functional outcome of metacarpal fractures managed by operative techniques and to compare the efficacy of different operative techniques.Methods: A total of 50 patients managed by various operative techniques by using k-wires, screws and plates. Functional outcome was assessed by using total active movement (TAM) and disabilities of the arm, shoulder and hand (DASH) scoring system at 6th week, 3rd month and at 6th month.Results: A total 47 fractures united and three fractures mal-united at the time of final assessment. Overall excellent and good results were achieved in 94% cases.Conclusions: Our finding suggests that open reduction and internal fixation with k-wire is most preferable method among all other operative techniques.

Ankle arthrodesis using computer assisted external fixator in patients with end-stage ankle arthrosis

Objective. Ankle arthrosis is an end stage disease for the ankle that happens because of posttraumatic arthropathies or inflammatory diseases. Ankle arthrodesis is the gold standard for ankle arthritis. We present the functional outcome for a mid-term follow up study of the patients who underwent trans fibular ankle arthrodesis fixated with hexapod type external fixator through a distal fibular grafting technique. Materials and Methods. A number of 18 patients with trans fibular ankle arthrodesis were included in this study, out of which 6 were female and 12 were male. The mean age at surgery was 57.6 (ranging from 45 to 73). All the patients underwent follow up for a mean follow up period of 27.5 months (ranging from 24 to 35 months). One of the patients had undergone ankle-related surgery for 9 times. The others had undergone 4 or more ankle-related surgeries. Results. Ankle fusions resulted in bony union within postoperative 4.1 months (ranging from 3 to 6 months). None of our patients had superficial or deep infection, soft tissue problems or problems about the external fixator. The mean preoperative AOFAS score was 52.4, and the postoperative AOFAS score was 78.2. We had 7 excellent (38.8%), and 11 (61.1%) good results. We had two cm shortening in 2 patients, 1.5 cm shortening in 1 patient and 1 cm in 5 patients. Conclusions. We have found this method to be useful to be applied to patients, especially to those who undergo lots of surgeries and for whom amputation is a last option.

Here we present two cases in older adult patients with highly destructive changes in ankle joints (Larsen Grade IV) and who underwent retrograde intramedullary nail fixation with fins. In both patients, bony union was achieved, full weight-bearing was attained 3 months after surgery and good functional outcome was acquired.

Open Posterior Glenoid Reconstruction Using a Distal Tibial Allograft

Background: Posterior instability is less common than anterior instability but can be seen in contact athletes and posttraumatically. Distal tibial allograft reconstruction for glenoid bone loss was first described by Provencher and colleagues in 2009 and an arthroscopic technique for posterior glenoid reconstruction using a distal tibial allograft was later described by Gupta et al in 2013. Indications: The primary indications for posterior distal tibial allograft include the failure of conservative management, recurrent instability after an arthroscopic stabilization, or glenoid bone loss > 20% to 25%. Technique Description: The patient is positioned in lateral decubitus, and examination under anesthesia is performed. Following arthroscopic evaluation, an incision is made medial to the posterolateral aspect of the acromion at the glenohumeral joint level. Electrocautery is carried to the deltoid, which is split in line with its fibers. A split between the infraspinatus and teres minor is performed. Vertical capsulotomy is performed, and deep retractors are placed. Attention is turned to the back table for graft preparation. The graft is measured, marked on the lateral aspect of the articular surface, and cut accordingly. Two 3.5-mm holes are drilled 1 cm apart, and the graft is thoroughly irrigated before being placed into the wound. A 2.5-mm drill is used in the 3.5-mm holes, and two 3.5-mm solid fully threaded screws are placed under power and tightened by hand. The wound is closed in the traditional fashion. Results: Graft nonunion and/or resorption are the primary concerns following posterior distal tibial allograft. Amar et al found no cases of nonunion or partial unions on 6-month computerized tomography (CT) scan, most patients having no or <50% resorption. Millet et al also found bony union by CT scan and improved patient-reported outcome measures. A case series by Gilat et al found 90% of patients reported restoration of stability. Discussion/Conclusion: Posterior distal tibial allograft is a successful surgical intervention for patients with recurrent posterior shoulder instability with glenoid bone loss.

Feasibility of lateral mass screw insertion in patients with the risky triad of C1: evaluation of the over-the-arch technique

OBJECTIVE The objective of this study was to evaluate the feasibility and complications of the over-the-arch (OTA) technique for screw insertion into the C1 lateral mass in patients in whom conventional techniques (i.e., posterior arch [PA] and inferior lateral mass [ILM]) are not feasible due to 1) PA with a very small height (< 3.5 mm), 2) a caudally tilted PA blocking the inferior part of the C1 lateral mass, or 3) loss of height at the ILM (< 3.5 mm). METHODS The authors reviewed the medical records of 60 patients who underwent C1 screw fixation with the OTA technique (13 screws) and the PA/ILM technique (107 screws) between 2011 and 2019. Vertebral artery (VA) injuries, screw malposition, and bony union were radiologically assessed. Clinical outcome measures, including Neck Disability Index (NDI), Japanese Orthopaedic Association (JOA) scale score, and occipital neuralgia, were recorded. RESULTS Thirteen OTA screws were successfully inserted without any major complications. NDI and JOA scale scores did not show significant differences between the two groups at final follow-up. No VA injuries were recognized during screw insertion. There was no evidence of ischemic damage to the VA or bony erosion in the occiput or atlas. Medial wall violation was observed in 1 screw (7.7%); however, no C0–1, C1–2, or lateral wall violations were observed. No patients developed new-onset neuralgia postoperatively after C1 fixation with the OTA technique. CONCLUSIONS The OTA technique was safe and useful for C1 screw fixation in patients in whom conventional techniques could not be employed.
