Malignant transformation in chronic osteomyelitis

Diogo Lino Moura; Rui Ferreira; António Garruço

Introduction Carcinomatous degeneration is a rare and late complication developing decades after the diagnosis of chronic osteomyelitis. Objectives To present the results from a retrospective study of six cases of squamous cell carcinoma arising from chronic osteomyelitis. Methods Six cases of chronic osteomyelitis related to cutaneous squamous cell carcinoma were identified. The cause and characteristics of the osteomyelitis were analyzed, as well as time up to malignancy, the suspicion signs for malignancy, the localization and histological type of the cancer, and the type and result of the treatment. Results The mean time between osteomyelitis onset and the diagnosis of malignant degeneration was 49.17 years (range: 32–65). The carcinoma resulted from tibia osteomyelitis in five cases and from femur osteomyelitis in one. The pathological examination indicated cutaneous squamous cell carcinoma in all cases. All the patients were staged as N0M0, except for one, whose lomboaortic lymph nodes were affected. The treatment consisted of amputation proximal to the tumor in all patients. No patient presented signs of local recurrence and only one had carcinoma metastasis. Conclusion Early diagnosis and proximal amputation are essential for prognosis and final results in carcinomatous degeneration secondary to chronic osteomyelitis.

Diogo Lino Moura; Filipe Alves; Rúben Fonseca; João Freitas; José Casanova

Objective  This was a retrospective observational study in patients submitted to intramedullary nail fixation after established or impeding pathological humerus-shaft tumoral fracture in the context of disseminated tumoral disease along 22 years of experience at the same institution. Methods  Sample with 82 patients and 86 humeral fixations with unreamed rigid interlocking static intramedullary nail by the antegrade or retrograde approaches. Results  The most prevalent primary tumors were breast carcinoma (30.49%), multiple myeloma (24.39%), lung adenocarcinoma (8.54%), and renal cell carcinoma (6.10%). The average surgical time was 90.16 ± 42.98 minutes (40-135 minutes). All of the patients reported improvement in arm pain and the mean Musculoskeletal Tumor Society (MSTS) score rose from 26% in the preoperative period to 72.6% in the evaluation performed in patients still alive 3 months after the surgery. The overall survival was 69.50% 3 months after the surgery, 56.10% at 6 months, 26.70% at 1 year, and 11.90% at 2 years. No death was related to the surgery or its complications. There were only 4 surgery-related complications, 1 intraoperative and 3 late, corresponding to a 4.65% complication risk. Conclusion  Closed unreamed static interlocking intramedullary nailing (both in the antegrade or retrograde approaches) of the humerus is a fast, safe, effective, and low morbidity procedure to treat pathological fractures of the humerus shaft, assuring a stable arm fixation and consequently improving function and quality of life in these patients during their short life expectation.

Diogo Lino Moura; Augusto Reis e Reis; João Ferreira; Manuel Capelão; José Braz Cardoso

Objective This study aims to describe the surgical approach to such injuries and to present the clinical and functional outcomes obtained in a cohort of patients. Methods This is an observational retrospective study that included 153 patients with acute acromioclavicular joint dislocation, operated between 1999 and 2015. Clinical evaluation included the following outcomes: Constant functional scale, development of complications, time to return to previous work/sport activities, and satisfaction index. The contra-lateral (uninjured) shoulder was used as control in subjective outcomes. Radiological evaluation was performed in order to monitor signs of loss of reduction, degenerative joint changes, and coracoclavicular calcifications. Results The mean age was 29.20 ± 9.53 (16–71), with a large male predominance (91.5%). Follow-up lasted 55.41 ± 24.87 (12–108) months. The mean Constant score attained was 96.45 ± 4.00 (84–100) on operated shoulders and 98.28 ± 1.81 (93–100) on contralateral ones. Almost all patients (98.69%) were satisfied with the surgical results. Worse outcomes were observed in acromioclavicular joint dislocations of increasing grade (from type III to V, but worse for type IV), both concerning the Constant score and return to work or sport. The overall incidence of complications was considered low, with the most prevalent being Kirschner wire failure and isolated coracoclavicular ligament calcifications. Conclusion The surgical technique described is an excellent option in the treatment of acute acromioclavicular joint dislocations of Rockwood grades III to V. This is corroborated by the excellent clinical and functional outcomes and the low rate of complications.

High congenital hip dislocation in adults - arthroplasty and functional results

Diogo Lino Moura; António Figueiredo

Objective Retrospective case–control study on the authors’ experience regarding arthroplasty in high congenital dislocations of the hip in adults. Methods Sample with 11 high congenital hip dislocations (Hartofilakidis type C) that occurred in seven patients, who were submitted to hip arthroplasty by the same surgeon and with the same surgical technique. Mean follow-up period was 4.32 ± 2.67 years (minimum one year) and all patients were evaluated by the same examiner. Results All the arthroplasties had cementless fixation, with application of screwed acetabular cups, conical femoral stems, and a metal-polyethylene articular pars. In every patient, shortening femoral osteotomies were performed at subtrochanteric or supracondylar locations. The mean Harris Hip Score at the last evaluation was 88.55 ± 4.50 (range 81–94). The mean time with high dislocation of the hip (42.91 ± 14.59 years, range 19–68) showed a significant inverse correlation with Harris Hip Score (r = 0.80; p = 0.003). All patients reported important relief of pain complaints and are capable of ambulation without any external support. In the unilateral dislocations, leg length discrepancies were fully corrected; in the bilateral cases, isometric limbs were achieved in all patients. All osteotomies consolidated, with a mean interval of 3.27 ± 0.47 months. There were complications in 18.18% of the sample: one iatrogenic intraoperative fracture of the greater trochanter and a transitory sciatic neurapraxia. Conclusion Despite being a demanding surgery with a reportedly high complication rate, total hip arthroplasty in high congenital dislocations, when properly indicated and technically correctly performed, allows an improvement in function and quality of life.

Diogo Lino Moura; Augusto Reis e Reis; João Ferreira; Manuel Capelão; José Braz Cardoso

Objective Retrospective case–control study of authors experience in the modified Bristow-Latarjet procedure for treatment of recurrent traumatic anterior glenohumeral dislocation with glenoid bone injury. Methods Sample with 102 recurrent glenohumeral dislocation cases submitted to modified Bristow-Latarjet procedure. Indications included situations of recurrent traumatic anterior glenohumeral instability with more than two dislocation episodes and with glenoid bone attritional or fragmentary injuries, without possibility of reconstruction. Mean follow-up time was 5.33 ± 2.74 years (minimum 1; range 1–13). Results The mean Walch-Duplay Score at the last evaluation was 91.23 ± 11.46 (range 15–100). The functional score of patients with glenoid bone loss greater than 20% did not show a significant difference in comparison with patients with glenoid bone loss lower than 20% (90 vs. 92, respectively). The functional score also did not show a significant difference between sports practice categories and between recreational and competitive practice, being excellent (greater than 90) in every category. There were no dislocation recurrences and the only complications were a case of persistent instability and a screw revision. Mild glenohumeral osteoarthrosis imaging signs were identified in 7.84% of the patients; however, their functional scores were not significantly different in comparison to other patients. Conclusion The modified Bristow-Latarjet procedure is a very effective procedure with few complications in the medium-term, showing very satisfactory functional outcomes in the treatment of recurrent traumatic anterior glenohumeral dislocation associated with glenoid bone injury.

Desartrodese de anca – relato de três casos

Diogo Lino Moura; António Figueiredo

Hip desarthrodesis, which is the conversion of an arthrodesis or of a surgical bone fusion into a hip replacement arthroplasty, is a difficult and challenging operation because of the need of a joint reconstruction in cases with bone fusion and an often long-term immobilization between the femur and the acetabulum, with important anatomic changes, retractions of adjacent soft tissues, and an associated limb shortening. Hip arthrodesis is an operation performed less and less; consequently, its desarthrodesis is even rarer. The present report details three rare cases of patients with long-term hip arthrodesis who were submitted to hip replacement conversion arthroplasty; it describes the applied surgical techniques and their clinical and functional outcomes.

Laceração da artéria ilíaca externa por migração de prótese da anca

Diogo Lino Moura; Mário Moreira; Luís Antunes; Alfredo Gil Agostinho; Manuel Fonseca; António Albuquerque

Hip arthroplasty is a common and safe intervention in orthopedic surgery. However, the proximity of this joint to large vessels makes the occurrence of vascular injury a rare but serious and possibly lethal complication of this surgical technique. Acute vascular injuries in the context of a hip arthroplasty have variable etiologies and clinical presentations, and are more common in revision surgeries and in situations of medial intrapelvic migration and of chronic infection of the hip prosthesis. In the present article, the authors present a case of acute and late major vascular complication in the context of hip arthroplasty revision. The patient developed an acute laceration of the external iliac artery caused by chronic and progressive medial intrapelvic acetabular migration of the hip prosthesis associated with chronic infection.

Diogo Lino Moura; José Pedro Marques; Pedro Matos; Luís Antunes; Óscar Gonçalves; António Albuquerque

Tibiofemoral unilateral knee dislocations are uncommon, making bilateral dislocations even rarer injuries. Knee dislocation is considered one of the most serious injuries that can affect this joint. Associated complications such as popliteal artery injury are responsible for the important morbidity in these patients. The authors report the case of a 52-year-old man with a traumatic bilateral knee dislocation with associated bilateral popliteal arterial injury. His clinical presentation along with radiographic and angiographic findings are described. Surgical and non-surgical treatment and functional outcomes are also reported.

Hip disarticulation - case series analysis and literature review

Diogo Lino Moura; António Garruço

Objective To present a retrospective study of 16 patients submitted to hip disarticulation. Methods During the period of 16 years, 16 patients who underwent hip disarticulation were identified. All of them were studied based on clinical records regarding the gender, age at surgery, disarticulation cause, postoperative complications, mortality rates and functional status after hip disarticulation. Results Hip disarticulation was performed electively in most cases and urgently in only three cases. The indications had the following origins: infection (n = 6), tumor (n = 6), trauma (n = 3), and ischemia (n = 2). The mean post-surgery survival was 200.5 days. The survival rates were 6875% after six months, 5625% after one year, and 50% after three years. The mortality rates were higher in disarticulations with traumatic (66.7%) and tumoral (60%) causes. Regarding the eight patients who survived, half of them ambulate with crutches and without prosthesis, 25% walk with limb prosthesis, and 25% are bedridden. Complications and mortality were higher in the cases of urgent surgery, and in those with traumatic and tumoral causes. Conclusion Hip disarticulation is a major ablative surgery with obvious implications for limb functionality, as well as high rates of complications and mortality. However, when performed at the correct time and with proper indication, this procedure can be life-saving and can ensure the return to the home environment with a certain degree of quality of life.
