The presence of anterior hip dislocation along with contralateral posterior hip dislocation in the absence of other major traumas is a distinctly rare injury pattern. We report such a case, along with a review of previous cases. A 40-year-old male patient after motorcycle skidding had posterior dislocation of the left hip and anterior dislocation of the right one without other associated injuries. The patient underwent successful closed reduction of both hips. The clinical course and follow-up assessment of the patient was uneventful.

A 28-yr-old woman presented with both hip pain that started sequentially during the peripartum period. Diagnosis of transient osteoporosis of the hip (TOH) was made based on typical findings of plain radiographs and magnetic resonance images. The subchondral trabeculae of the femoral head were evaluated on serially taken coronal multiplanar reformation computerized tomogram images. At 4 weeks after pain onset, marked decrease in the sclerotic density with irregular discontinuation was observed in the primary compression trabeculae. At 12 weeks, a focal area of irregular thickening of trabeculae was observed. At 20 weeks, sclerotic density of trabeculae recovered markedly and the focal area of irregular trabecular thickening disappeared. At 1 yr, subchondral trabeculae recovered almost completely. The evidence of subchondral trabecular injury was observed in the femoral heads of TOH.

Femoral head fractures without dislocation or subluxation are extremely rare injuries. We report a neglected case of isolated comminuted fracture of femoral head without hip dislocation or subluxation of one year duration in a 36-year-old patient who sustained a high energy trauma due to road traffic accident. He presented with painful right hip and inability to bear full weight on right lower limb with Harris hip score of 39. He received cementless total hip replacement. At latest follow-up of 2.3 years, functional outcome was excellent with Harris hip score of 95. Such isolated injuries have been described only once in the literature and have not been classified till now. The purpose of this report is to highlight the extreme rarity, possible mechanism involved and a novel classification system to classify such injuries.

Unstable posterior acetabular fractures resulting from high energy trauma present major challenges to any orthopedic surgeon especially if the treatment has been delayed.
OBJECTIVE: The purpose of this paper is to describe the early results of delayed treatment of a series of patients with posterior acetabular fractures with concomitant hip dislocations, surgically approached using the Kocher-Langenbeck with a trochanteric flip osteotomy.
METHODS: Five (5) male patients (mean age 35.6 years, range 23-58 years) who sustained unstable posterior acetabular fractures, underwent surgical treatment using the Kocher-Langenbeck approach with the trochanteric flip osteotomy, during the period of May 2014 to October 2015. Clinical and radiographic evaluations of each patient were performed, while complications were documented.
RESULTS: Mean follow-up was 8 weeks (range 2-12 weeks). There was adequate exposure of the posterior and superior acetabulum in all patients. Post-operative radiographs in four of five patients were graded "anatomic" while hip range of motion of these four patients averaged 78.7% of the uninjured hip. One patient with "poor" reduction underwent a second operation to reserve a failure of the initial fixation using the same surgical approach. No other complications were reported.
CONCLUSION: This modified approach provides adequate exposure of both posterior and superior acetabulum and also allows inspection of the articular surfaces of both acetabulum and femoral head, which are limited in the standard Kocher-Lagenbeck approach. With excellent exposure, congruent reduction can readily be achieved while permitting early hip range of motion post-surgery.

We describe the case of a healthy young man with a femoral head fracture by low-energy trauma that occurred without evidence of hip dislocation. While plain radiographs showed no definite fracture or dislocation, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a femoral head fracture with a wedge-shaped cortical depression at the superomedial aspect of the femoral head. Our patient reported feeling that the right hip had been displaced from its joint for a moment. This probably represented subluxation with spontaneous relocation. The characteristic findings and possible mechanisms of this fracture were postulated on the basis of the sequential 3 dimensional-CT and MRI. The clinical results of conservative treatment were better than those of previously reported indentation fractures.

A subchondral insufficiency fracture (SIF) of the femoral head is a recently proposed concept, which needs to be differentiated from osteonecrosis. Clinically, SIF has generally been observed in the osteoporotic elderly women or renal transplant recipients. Radiographical changes are not obvious in its early phase, however, some cases undergo subchondral collapse (crescent sign). On the T1-weighted magnetic resonance images, a low intensity band is one of the characteristic imaging appearances, which corresponds histologically to the fracture line and associated fracture repair tissue. Therefore, the shape of the low intensity band generally tends to be irregular, disconnected, and convex to the articular surface. The prognosis of SIF is not clearly established. Some cases show resolution of the symptoms by the conservative treatments, while other cases show rapid progression of the collapse such as rapidly progressive arthrosis of the hip.

Anterior traumatic dislocations of the hip are much less common than posterior dislocations. To date, 14 cases of open anterior dislocation of the hip associated with such injuries, acetabular and femoral head fractures and femoral vascular and nerve damage have been reported. We present a case of a 23-year-old male who sustained open anterior dislocation of the hip with ipsilateral fracture of the greater trochanter after an accident on the public highway. Additional lesions included an iliac wing fracture and a perineal wound. We report this case because of the rarity and seriousness of this injury due to its progressive complications and difficulties related to its management, which are typical to a developing country like ours.

PURPOSETo investigate the mid-term curative effects of the treatment of Pipkin type IV femoral head fractures using a reconstruction plate and bioabsorbable screws and provide the evidence for clinical practice.

METHODSFrom February 2010 to September 2014, 21 patients with Pipkin type IV femoral head fractures were treated surgically. There were 13 males and 8 females with an average age of 41.1 years (range, 20-65 years). The causes of the fractures included traffic accidents (13 cases), falls from a height (four cases), heavy lifting injuries (three cases), and sport injury (one case). All patients were followed up with radiography and three-dimensional reconstruction computed tomography and other checks and any complications were actively managed. Closed reduction of fracture-dislocation of the hip was attempted under general anesthesia using the Kocher-Langenbeck approach. Femoral head fractures were treated with internal fixation or excision based on the size of the fracture fragments, whereas acetabular fractures were fixed with a reconstruction plate and screws following anatomic reduction.

RESULTSThe incisions healed by primary intention in all patients after surgery, without any infection, deep venous thrombosis, or other complications. All 21 patients were followed up for 36-76 months, with an average follow-up duration of 49 months. Postoperative imaging data showed that all dislocations and fractures were anatomically reduced, and bony union of the fractures was achieved. Heterotopic ossification was found in four patients, post-traumatic osteoarthritis in three, and avascular necrosis of the femoral head in two. At the final follow-up, the assessment of hip joint function according to the Thompson-Epstein scoring scale was excellent in 10 cases, good in six cases, fair in three cases, and poor in two cases. The rate of excellent and good functional outcomes was 76.1%.

CONCLUSIONThe mid-term curative effects of a reconstruction plate and bioabsorbable screws in the treatment of Pipkin type IV femoral head fractures is significant, and such the treatment can significantly improve the patient's joint function and quality of life.

OBJECTIVETo observe the application effect of minimally invasive decompression, bone graft implantation and metal trabecular bone reconstruction system for early stage osteonecrosis of femoral head and discuss the treatment of hip-salvage operation in early stage osteonecrosis of femoral head;

METHODSFrom January 2010 to June 2011, 50 patients (62 hips) Which were osteonecrosis of femoral head of early stake,were treated with minimally invasive decompression, bone graft implantation and metal trabecular bone reconstruction system, including 31 males (40 hips), 19 females (22 hip) with an average age of 36.2 years old ranging from 22 to 54 years old. The course of disease was from 6 to 15 months (averaged 10.5 months). Among them, 19 cases (23 hips) were steroid-induced, 25 cases (33 hips) were alcohol-induced, 6 cases (6 hips) were idiopathic; According to ARCO stage, 28 hips were at stage I, 34 hips were at stage II. All of them were diagnosed as femoral head necrosis by imaging examination before operation. Then each patient was followed to assess by Harris hip score, curative effect, and conduct the femoral head survival analysis during the postoperation.

RESULTSAll patients had finished operation, the operation time was between 30 and 85 min, intraoperative blood loss was 50 to 220 ml, and 47 cases (58 hips) were follow-up from 24 to 46 months with an average of 34.05 months. As compared with preoperative, the Harris hip score at the last follow-up was improved, the difference was statistically significant (P<0.01). The Harris hip score, curative effect and survival time of femoral head in ARCO stage I was superior to these in ARCO Stage II, the difference was statistically significant (P< 0.05).

CONCLUSIONEffect of minimally invasive decompression,bone graft implantation combine with the metal trabecular bone reconstruction system for early stage osteonecrosis of femoral head was good,it could significantly improve the Harris hip score, increase the femoral head survival time, delay the hip replacement, and performance better in ARCO stage I.
