Extra-osseous tenosynovial chondromatosis is rare and has a high rate of local recurrence. We report a 23-year-old man who presented with a 6-month history of pain and swelling of the right middle finger and painful limitation of the ring finger flexion secondary to this condition. Surgical exploration revealed multiple loose bodies of varying size arising from the flexor tendon sheath. Histopathological examination revealed mature chondroid tissue and focal calcification. After 2 years of follow-up, the patient had achieved an excellent functional recovery and showed no evidence of recurrence.

Background:Charcot's neuroarthropathy of ankle leads to instability, destruction of the joint with significant morbidity that may require an amputation. Aim of surgical treatment is to achieve painless stable plantigrade foot through arthrodesis. Achieving surgical arthrodesis in Charcot's neuroarthropathy has a high failure rate. This is a retrospective nonrandomized comparative study assessing the outcomes of tibio-talar arthrodesis for Charcot's neuroarthropathy treated by uniplanar external fixation assisted by external immobilization or retrograde intramedullary interlocked nailing.Materials and Methods:Records of the authors′ institution were reviewed to identify those patients who had undergone ankle fusion for diabetic neuroarthropathy from January 1998 to December 2008. A total of11 patients (six males and five females) with a mean age of 56 year and diabetes of a mean duration of 15.4 years with ankle tibio-talar arthrodesis using retrograde nailing or external fixator for Charcot's neuroarthropathy were enrolled for the analysis. Neuropathy was clinically diagnosed, documented and substantiated using the monofilament test. All procedures were performed in Eichenholz stage II/III.Six patients were treated with uniplanar external fixator, while the remaining five underwent retrograde intramedullary interlocking nail. The outcomes were measured for union radiologically, development of complications and clinical follow-up, according to digital archiving systems and old case notes.Results:All five (100%) patients treated by intramedullary nailing achieved radiological union on an average follow-up of 16 weeks. The external fixation group had significantly higher rate of complications with one amputation, four non unions (66.7%) and a delayed union which went on to full osseous union.Conclusion:The retrograde intramedullary nailing for tibio-talar arthrodesis in Charcot's neuroarthropathy yielded significantly better outcomes as compared to the use of uniplanar external fixator.

Background:The study aims at providing Incidence rates with the use of posterior approach and the role of gender in development of HO after total hip arthroplasty in an Indian scenario. Methods: 401 patients who had underwent total hip arthroplasty using posterior approach were studied retrospectively with the help of X-rays after a stipulated period of 12 weeks from the hospital database. The X-rays which were studied for any evidence of Hetertopic ossification and if present HO was classified using Brookers classification. The incidence rates were thus calculated along with incidence of each of the subtypes of HO with the use of posterior approach. The predisposition of sex for development of HO were noted. Results: Evidence of HO was found in 32.9 percent of cases (132/401) with the incidence of type 1 -24.4 % (98/401), type 2 -6.4% (26/401), type 3 -1.9% (8/401), type 4-Nil. The male to female ratio of total hip arthroplasty was found to be 65.08 % percent (261/401) males as compared to 34.92 percent females (140/401). Among males 35.63 % (93/261) percent of patients developed HO and among females 27.85 percent (39/140) of patients developed HO. Also out of the 401 hips replaced 370 were uncemented THRs and 31 were cemented THRS. 36.67 % (136/370) developed HO in uncemented implants and 29.03 % (9/31) developed HO in cemented implants. Conclusion:The study demonstrated an incidence of 32.9% HO after primary THA in Indian population after using posterior approach with its incidence being higher in males.
