    LYTIC LESIONS OF DISTAL RADIUS IN CHILDREN: A RARE TUBERCULAR PRESENTATION

    Hand Surgery01 Jan 2014

    Introduction: We report the presentation, management, and outcome in five children with osteoarticular tuberculosis of distal radius.

    Patients: Patients were recruited in a prospective study. All patients underwent an open biopsy, curettage and diagnosis confirmed by histopathological/microbiological examination. In cavitary lytic lesions, bone grafting was also undertaken. The multidrug anti-tubercular chemotherapy was given for one year.

    Observations: Five patients were included in the study. The average follow-up post-completion chemotherapy was 34.8 months. Bony lesions presented as a poorly defined radiolucent lytic area in metaphysis, cavitary lytic lesions with or without sequestrum or spanned the physeal plate. At final follow-up, except for one case, a full pain free range of movements was achieved in all cases. Fibular graft was used in two cases with cavitary lesions and incorporated well in both cases.

    Conclusions: Tuberculosis can involve the adjacent physis and can be multifocal. The presentation is usually lytic with minimal sclerosis. For smaller ill defined lesions, curettage and multidrug anti-tubercular chemotherapy results in excellent outcome. Cavitary lytic lesions should be bone grafted as there is a risk of pathological fractures.

    Osteosynthesis of Postosteomyelitic Forearm Defects in Children Using a Modified Bone Grafting Technique: The Fibular Intramedullary Bridging Bone and Additional Grafting (FIBBAG)

    Background: There are many options to treat post osteomyelitic gaps in forearm bones. We report a pediatric series with postosteomyelitic forearm segmental defects reconstructed with fibular only graft: the non vascular fibular intramedullary bridging bone and additional grafting (FIBBAG) and the results thereof.

    Methods: Outcomes in 8 patients treated with fibular strut and overlay matchstick grafts were retrospectively assessed. The clinical results were expressed as forearm shortening, range of motion at elbow and wrist joint. The radiological evaluation included time to union, presence of fractures and recurrence of infection, if any.

    Results: The average patient age was 6 years (range, 3–12 years). The radius was involved in 6 and ulna in 2. Union occurred in all patients. The average intraoperative gap to be spanned was 5.86 cm (range, 3–14 cm). The average time for union was 6.63 months (range, 2–14 months). Two patients required additional bone grafting procedures. No graft fatigues/fractures were noted in available follow up. There was no recurrence of infection in any case. A positive ulnar variance was seen in 3 patients at follow up. Forearm shortening was a major cosmetic limitation following the procedure.

    Conclusions: Fibular strut and additional bone grafting (FIBBAG) is one of the viable options for reconstruction of post osteomyelitic forearm defects in children with low procedural complication rate.

    Finger Rescue Using the Induced Membrane Technique for Osteomyelitis of the Hand

    Background: The induced membrane technique is now commonly used for large diaphyseal bone defects. Recently, several papers reported using the induced membrane technique for hand surgery. We applied this technique with some modifications to treat osteomyelitis of the phalanges.

    Methods: This study included six men and one woman with a mean age of 56 years. The causes of osteomyelitis included animal bite (n = 3), trauma (n = 3), and an indwelling needle (n = 1). Two-staged surgeries were performed, including an initial stage with radical debridement of the infected tissue and placement of a cement spacer into the bone defect. Four weeks after the first stage, a bone graft was performed. A bone block with cortex was harvested from the iliac crest or radius, and costal cartilage was used for proximal interphalangeal (PIP) joint arthroplasty in two cases. Grafted bones were fixed with a mini screw or an external fixator.

    Results: In all cases, the infection subsided, and bone union was obtained within two to three months. No absorption of the grafted bone was observed. In the two cases with PIP joint defect, joint motion without pain was preserved at 56° and 26°.

    Conclusions: A short interval between the two surgical stages of the induced membrane technique could be advantageous for patients in terms of time and financial burden and early rehabilitation of movement. Cortico-cancellous bone grafts were able to maintain bone length and stability with screw fixation. In the cases with PIP joint defects, instead of arthrodesis, we performed PIP arthroplasty using costal cartilage, eventually obtained some motion without pain. The induced membrane technique was useful and technically feasible for treating osteomyelitis in the hand, and secondary joint reconstruction was possible to obtain some motion.

    Finger Amputation after Pinning of the Distal Interphalangeal Joint for Acute Closed Tendinous Mallet Finger: A Rare but Devastating Complication

    The best treatment for mallet fingers is still a matter of debate. Numerous splints with different designs to keep the distal interphalangeal (DIP) joint in extension have been described in literature. The outcomes of splint treatment are generally good with occasional reports of minor skin complications. Percutaneous Kirschner-wire pinning of the DIP joint for closed tendinous mallet finger represents a alternative treatment modality that reliably immobilises the joint and does not need much patient compliance or use of an external splint. We report a rare but devastating complication of percutaneous pinning of the DIP joint for closed tendinous mallet finger.

    Diagnostic Challenges of Metacarpal Tuberculosis in Paediatrics: A Case Report

    Metacarpal tuberculosis is rare even in endemic areas. This is a report of a 12-year-old girl with gradual, painless swelling of the dorsal aspect of the right hand over a 2-year period. She developed a discharging sinus over the mass after a traumatic incident. The radiographs showed a well-defined, expansile osteolytic lesion. Blood test, fine needle aspiration biopsy and smears were not diagnostic. A second histologic examination with phenotypic test was required for diagnosis and to begin appropriate chemotherapy. Establishing the diagnosis was not straightforward, even though we suspected tuberculosis.
