Early or delayed limb lengthening after acute shortening in the treatment of traumatic below-knee amputations and Gustilo and Anderson type IIIC open tibial fractures: THE RESULTS OF A CASE SERIES

We present the results of 13 patients who suffered severe injuries to the lower leg. Five sustained a traumatic amputation and eight a Gustilo-Anderson type IIIC open fracture. All were treated with debridement, acute shortening and stabilisation of the fracture and vascular reconstruction. Further treatment involved restoration of tibial length by callus distraction through the distal or proximal metaphysis, which was commenced soon after the soft tissues had healed (n = 8) or delayed until union of the fracture (n = 5). All patients were male with a mean age of 28.4 years (17 to 44), and had sustained injury to the leg only. Chen grade II functional status was achieved in all patients. Although the number of patients treated with each strategy was limited, there was no obvious disadvantage in the early lengthening programme, which was completed more quickly.

Lengthening of a thumb distal phalanx replanted to its metacarpus because of loss of the proximal phalanx: case report.

We report a successful thumb replantation by resecting the remnants of the crushed proximal phalanx and uniting the distal phalanx with the thumb metacarpal. The procedure resulted in extreme shortening, which we managed by distraction lengthening and deepening of the first webspace.

Treatment of osteonecrosis of the femoral head with free vascularized fibular grafting: Results of 7.6-year follow-up

Objectives The aim of this study was to determine long term follow up of the patients who had femoral head osteonecrosis and had been treated with free vascularized fibular grafting. Patients and methods We retrospectively reviewed 28 hips of 21 patients who had undergone free vascularized fibular grafting for the treatment of osteonecrosis of femoral head. There were 16 male and 5 female patients. The mean age of the patients at the time of surgery was 30.7 years (between 15 and 53 years). The mean follow-up time was 7.6 years (between 5 years and 9.2 years). Results During follow-up, one patient died because of leukemia, and one patient was lost. The remaining 26 hips of 19 patients were evaluated. According to the Ficat classification, at the time of surgery, 17 hips were in grade 2 and 9 hips were in grade 3. The post-operative Harris hip scores in grade II disease were excellent in 12 patients, good in 3 patients, and fair in 1 patient. In grade III disease, 1 patient was excellent, 5 patients were good, and 1 patient was fair. There was a significant increase in HHS scores (61 ± 9.7 vs 84 ± 17.8, p < 0.001). Conclusion Free vascularized fibular grafting yields extremely good results, particularly in pre-collapse stages of disease in young patients. The operation time does not mark increased if the surgical team is “familiar” with the procedure, and the residual fibular defect of the donor site does not impair the functions of daily living.

The Reconstruction of Foot Soft Tissue Defects by Tangential Debulking of the Latissimus Dorsi Flap

Reconstruction of foot soft tissue is challenging particularly in the presence of a large defect involving both dorsal and plantar surfaces. In large defects, use of a latissimus dorsi muscle (LDM) flap is the preferred coverage method, yet LDM flaps are bulky. Despite undergoing multiple debulking procedures, patients whose feet are repaired with LDM flaps must wear oversized custom-made shoes. We developed an approach to allow patients to wear regular shoes. In six patients, we used a debulking procedure that was based on tangential trimming of the flap to the level of thickness required for normal foot contour. All patients underwent debulking 3 months after initial LDM flap coverage. The mean duration of follow-up care was 21 months (range, 8 to 32 months). All flaps survived a secondary debulking procedure. One patient developed an ulcer at the weight-bearing area of a sole. All six patients were able to wear regular shoes without difficulty.

Neglected lunate dislocation presenting as carpal tunnel syndrome

Abstract Most of carpal tunnel syndrome cases are idiopathic, and secondary causes are so rare that can be easily missed. We present a patient with neglected undiagnosed lunate dislocation compressing on median nerve causing its signs and symptoms.

Trigger finger at the carpal tunnel level: three case reports.

Although trigger finger occurs mostly due to a problem at the A1 pulley various other causes have also been reported. We present three patients with different tumors at the carpal tunnel as a cause of triggering. All patients were treated with local excision.

Massive subcutaneous emphysema and pneumomediastineum after finger subtotal amputation with barotrauma.

BACKGROUND Advancement of pressurized air through subcutaneous tissue after barotraumas involving skin laceration has been documented in the literature. The type and anatomic location of injury, amount of pressure, and time elapsed all play a role in determining the destination of the air advancing through tissues. OBJECTIVES To report a case demonstrating the vascular system as the anatomic pathway for subcutaneous pressurized air resulting from an industrial accident. CASE REPORT We present the case of a 28-year-old laborer wounded by an air valve blast. An enormous accumulation of air was released through a subtotal fingertip amputation. The clinical appearance of massive subcutaneous emphysema around the upper extremity, neck, and chest suggested chest trauma to the clinicians, despite the absence of signs of respiratory distress. X-ray studies revealed pneumomediastinum. After confirmation that the respiratory system was undamaged, microsurgical repair of the injured finger was performed. Resolution of subcutaneous emphysema and pneumomediastinum was complete at the end of follow-up. CONCLUSION Compressed air injuries constitute a well-known form of industrial accident. Although most result in localized subcutaneous emphysema, the risk of pneumomediastinum should not be overlooked due to the anatomic structure of the vascular system. The clinician should consider the pressure of compressed air, and must be alert for potential complications.

Distraction lengthening of the proximal phalanx in distal thumb amputations.

OBJECTIVE Thumb amputation is a major cause of hand dysfunction, and the treatment for distal thumb amputations remains controversial. Although finger reconstruction methods using distraction lengthening are known to restore finger length and function, we found no reports in the literature regarding phalangeal lengthening in thumb amputations. We aimed to evaluate proximal phalangeal lengthening in thumb amputations at or near the interphalangeal (IP) joint. METHODS We retrospectively evaluated patients who had undergone distraction lengthening of the proximal phalanx of the thumb. All patients underwent osteotomy, either during the initial procedure or as a second-stage procedure. Distraction began 10 days after osteotomy with the use of an external fixator that remained in place until ossification of the gap occurred without bone grafting. Patients were evaluated using the QuickDASH score. RESULTS Fourteen patients with a mean age of 27 years and a mean follow-up period of 7 years were enrolled. The mean phalangeal lengthening achieved was 20 mm. Ossification occurred at all distraction sites, and the fixators were maintained for a mean of 85 days. The mean healing index was 42.5 days/cm. All 14 patients achieved the desired amount of phalangeal lengthening without major complications such as nonunion, premature union, or gross infection. CONCLUSION For reconstruction in cases of distal thumb amputations, distraction lengthening of the proximal phalanx can be used to improve absolute length, web space, and grip distance. The technique is safe and effective, improves functionality/cosmesis, and offers a low complication risk.

Acute emergency tibialization of the fibula: reconstruction of a massive tibial defect in a type IIIC open fracture

Gustilo type IIIC open fractures of the tibia are high-energy injuries necessitating long treatment periods and usually multiple surgical procedures and eventually resulting in high morbidity rates and even amputations. We present here a case involving a type IIIC open tibial fracture with massive loss of the entire tibial diaphysis, which we treated by performing acute tibialization of the fibula after revascularization of the posterior tibial artery in a single-stage emergency operation.

Lateral Antebrachial Cutaneous Nerve as a Donor Source for Digital Nerve Grafting: A Concept Revisited

Objective: The main objective of this study is to evaluate the availability of lateral antebrachial cutaneous nerve (LACN) autograft for acute or delayed repair of segmented digital nerve injuries. Patients and Methods: 13 digital nerve defects of 11 patients; treated with interposition of LACN graft that harvested from ipsilateral extremity were included in the study. Mean follow up period was 35, 7 months. The mean time from injury to grafting is 53, 3 days. The results of the mean 2PDT and SWMT values of injured /uninjured finger at the end of follow up period were evaluated with Paired T test. The correlation between the defect length and the difference of 2PDT, SWMT values between the uninjured and injured finger at the end of follow up period; were evaluated with Pearson - correlation analysis. Results: The mean value of our 2PDT and SWMT results are ~5,923, ~3, 52, respectively in which can be interpreted between the normal and diminished light touch. The defect length and difference percentage of SWMT values is positively and significantly correlated statistically. Mean length of interposed nerve grafts was 18.5 mm. The age of the patient and the mean values of 2PDT and SWMT with the difference % of 2PDT and % of SWMT are not statistically correlated. Conclusion: Based on results regarding sensory regaining at recipient side and negligible sensory deficit at harvesting side, we suggest that lateral antebrachial cutaneous nerve might be a valuable graft option for digital nerve defects.
